I'd expect to get an error (I know I've gotten them) if the
double-underscore syntax were incorrect or if you were specifying
non-existent fields, etc.  ForeignKey spanning search such as this does work
-- I just tried adding some to my DB (using both forward and backwards
relationships) and they worked correctly, even when more than five were
listed in a single search_fields list.

So I have no idea what is going wrong in your case.  I'd try simplifying
search fields to a single one that is not currently working.  If you specify
that one, does it work?  If not, check the SQL generated by the admin
(either turn on query logging at the database or use something like the
debug toolbar) for clues as to why the search isn't working.  If the one
field does work, add fields one at at time until it breaks, and see what
sort of clues you get then, and from the SQL generated then, etc.

First thing you need to do is figure out where the slowness
originates.  Is it from DB access? XML generation?

If it's from DB access, include the code you're using to fetch data.
If XML generation, likewise.

On the surface, that look like it should work. Which makes me suspect
some important detail has been lost in the simplification.

What does the my_data dictionary look like just before you execute the
"form = ..." line (print it out)?

Also, how is form_class specified? Finally, what is the exact error
Django gives you? Print out form._errors, for example.

Maybe somewhere in there the answer will jump out. Admittedly, all the
clues may already be there and I'm just missing the obvious, but I can't
see it right now.

On a related note, is there any particular reason you need to have
site_id in the form class at all? Even if it's a model form, you could
exclude it, and add it into the model object later, couldn't you? You
might be going about this slightly backwards by trying to force in
site_id when it's not something that actually needs to be validated or
form-processed.

Malcolm

Why do you have this field included in the form at all?  Not only do you not
want it to be required, but you do not even want to display it? So why it is
there?  Putting it there and then trying to fake out as though valid data
had been posted for it just seems like a backwards approach to whatever real
problem you are trying to solve.

Setting Bound Fields Programmatically

[Keyton Weissinger]

I have a form with the following fields (all required):
- first_name
- last_name
- site_id

I'd like to use a template to display only the FIRST two items to the
user for him to fill out:


{{ form.first_name }} 
{{ form.last_name }} 



Then when it gets posted back to me I'd like to set the site_id based
on a session variable or whatever like this (from my view):

if request.method == 'POST':
my_data = {'site_id':1234}
my_data.update(request.POST)
form = form_class(data=my_data, files=request.FILES)
if form.is_valid():
 process form here...


My problem is that I cannot get the form to validate. It keeps telling
me that site_id is not set.

How can I programmatically set this one form field's value and have
the user set the others without sending through a hidden field yada
yada.

Please help!

Thank you.

You can't really do that at the moment. You're talking about what we
call the "application" name, and that's taken from the Python name.

You could write a custom template for the admin interface that
hard-codes what you're after. Copying the existing template and putting
in an "if" template tag to test if the name's the one you want to
override. So it's not necessarily impossible and I've seen it done, but
you have to really want to do it.

Malcolm

Re: what type of data structure should I use?

[backdoc]

Thanks for the link.  I like that.  I'm going to see if I can use it.
I'd like to be able to do one query, then bring it into this plugin,
sort it 3 or 4 different ways on the client side.

I haven't really had any time today to look at it.  But, I also
thought about trying some kind of session object to hold the data.  I
could possibly use it to work with the jQuery plugin.

The function is called get_profile, not get_or_create_profile.

Some people would like it to create automatically, others prefer it to
be explicit. I'm in the latter camp: if a user should have a profile, I
should create it properly when creating the user (e.g. using a signal),
not have some magical transparency happen behind the curtain that hides
the bug of me forgetting to do so. After all, if you're creating a
profile, you might well need to initialise it in some particular default
way. So now get_profile() needs to be like get_or_create() and accept a
bunch of default arguments. Much more complicated.

It's a moot point, though. Changing it would introduce the sort of
backwards incompatibility we try to avoid.

Malcolm

Thanks for your help.  I finally found the problem after hours of 
banging my head against the wall.  It was simply the fastcgi script was 
always running.  I have to kill the fastcgi script after making changes 
to the .fcgi file or else the changes will never take effect.

The obvious guess would be permission problems. You have different
access permissions to the webserver. Does the webserver (the user that
is executing the fastcgi script) have permission to read the file? And
the directories leading down to the file (the latter will need "execute"
permission set for the "other" section on Unix-like systems).

Re: Returning large files from a view

Ultimately what they really need is:

from:

At least then it will be optimal for WSGI case.

Not, that's a NULL value. Blank has absolutely no technical meaning at
the database level and certainly not any kind of ambiguous one. That's
just confusing the issue.

You're correct that Django uses it as a data-entry-level term meaning
that the field was left blank, but wishing/hoping that it also
substitutes as NULL isn't making things any clearer.

As far as I'm concerned, this issue kind of died when somebody pointed
out the binary field case. That's a minimally valid example of why the
separation makes sense still.

Malcolm

I don't think this is the problem you think it is. URL pattern matching
in Django doesn't look at the hostname portion of the URL or the query
string (everything after the "?"). So those two URLs should look exactly
the same to Django. When you have DEBUG=True in your settings file, do
you really get the 404 screen saying it couldn't match any URL patterns?
If so, what pattern does it say it was trying to match?

It looks like something is going wrong in the runserver case, by the
way. Your form is submitted using a GET action, which means the
submitted URL should look like the second case (although the hostname
portion might well be different). It's not clear why you're using GET
and not POST there, by the way -- better to use normal form processing
practice -- which means action="post", not action="get" --  when you're
starting out so that the differences don't make things any harder than
they already are.

Malcolm

Use auxillary functions. Model fields carry no implicit "display"

the presentation.

Write some model methods that return the appropriate string format of
the given field. Or write some filters that accept a model object as the
input value and format it appropriately. Using template filters for
presentation changes always feels pretty natural to me. Model methods
work, but, as noted above, my inclination is always to use models as the
presentation-agnostic data object and set things up so that I can
control presentation indepedently of the data itself.

Malcolm

We'll need a bit more information here, since the devil's always in the
details. At a minimum, what is the output of

groupmembers.query.as_sql()

There may be a problem with exclude and nested querysets. I just
realised I haven't explicitly tested those.

Also, which database are you using? There are lots of SQL variations
between databases (for example, nested queries don't work with Oracle at
the moment for an unusual reason that I'll fix later today).

Re: what type of data structure should I use?

[Ozan Onay]

There's no need to keep selecting from the DB and refreshing the page.
You can re-sort the list client-side on AJAX response (with jQuery,
for instance). The tablesorter plugin (http://tablesorter.com/docs/)
is not exactly what you're looking for but will give you an idea of
how to sort client-side, if you're not sure.

That result is going to be database server specific and possibly also
dependent upon whether you specified the table or database as accepting
UTF-8 encoded strings or just plain ASCII. So which database are you
using?

[...]

A URLfield is just a character field and since you also create a
character field of the same length without an index and it worked, that
would seem to rule out this possibility.

NewBie Question about ForeignKey relationships

[Mark Jones]

Ok, here is some simple code:

class Maker(models.Model):
name = CharField(max_length=20)

class Auto(models.Model):
name = CharField(max_length)
maker = ForeignKey(Maker)


maker = Maker.objects.get(pk=1)

How do I get all the Autos made by this maker

I don't see a maker.autos (railsish)
All I have been able to figure out for this is:

Auto.objects.filter(maker=maker.id)# this works
Auto.objects.filter(maker=maker)# this works too

Is that all there is, or is there some maker.autos abstraction that I
just don't see.  The last method 2 methods both work, but it seems
awkward to use them given the fact that I have a Maker, and the
relationship between Maker and Auto is known in the models but via the
Manager interface requires restatement in (maker=maker.id) or

Re: Import models from CSV files?

[Victor Hooi]

heya,

The sample code request was just me being lazy =). Hmm, so you think
the csv parsing code should be in the upload processing? This would
just be a form with two boxes for the user to select the .csv files,
and an upload button. Better putting it here than in the model?

In terms of processing, well, there's only a little bit. One of the
files is a dump from a Lotus Notes view. It looks a little like this

Firstly, there were dropdowns (e.g. for Date, and Region) - those date
and regions apply to the rows below them - annoying, but easy to deal
with.

Also, the time is given as a start time and duration - I converted
this into a start_time and end_time.

Finally, the Sites and For columns can each contain multiple entries.
After parsing, I'm storing it as a list of users, each with a list of
access periods granted (containing the start_time, end_time and site -
and a few other things). So you go through, and create entries for
each user, for each of the sites, per line. Not too bad.

Heck, I'll just post the code (I'm halfway through working on it - may
not compile cleanly right now, but you get the idea).

http://dl.getdropbox.com/u/281283/access_requests.py

I guess the important thing is just the users being able to upload
the .csv files themselves, and dealing with weirdness in the input.

Cheers,
Victor

Shouldn't get_profile() create the profile object?

[Alvaro Mouriño]

I find myself checking for the existence of the profile object for the
user everytime I call the get_profile function or making sure that it
gets created with every user.

Is there a reason for this? Shouldn't the framework assure me that I
will get a profile whenever I call get_profile()? Even if it means
creating one?

Thanks!

(sorry, hit the send button to soon)

Else, you could eventually just pass the file object itself to
HttpResponse:

http://docs.djangoproject.com/en/dev/ref/request-response/#passing-iterators

... but I don't know if you will gain that much from doing so (wild
guess: this probably depends on how you deploy your django instance).
Also, this may (or not) cause problem with ressource (the file)
deallocation (but this can eventually be solved using some 'lazy'
proxy instead of the file object itself).

The files do not reside under our site's document root, because my  
boss does not want them there (for reasons that aren't entirely clear  
to me). Also, we want to do some extra processing before the file is  
served, e.g. increment an integer representing the number of  
downloads. Thirdly, we want to be able to force the browser to  
download the file instead of displaying it (in the case of PDFs, for  
example).

Re: Redirect parent from within iframe without losing session

I am getting a very similar problem when simply going between views
(all within the same domain), so it may be nothing to do with iframes.
I have put in a trace and can see that in some cases you enter the
view with all session variables set and when the session is next saved
all the variables have been  cleared.

Returning large files from a view

I would like to return a binary file from a view, and so far I have  
something like this:

def my_file(request):
 file_data = open("/path/to/file", "rb").read()
 response =  HttpResponse(file_data, mimetype="application/ 
whatever")
 response['Content-Disposition'] = 'attachment; filename=my_file'
 return response

Is there a better way to do this, especially for very large (> 10MB)  
files?

Re: How to impose a permission-based filter in admin?

[ZebZiggle]

Upon further research ... I'm suspecting I need to create a Manager
and override get_query_set(), but since I don't have a request object,
I can't get the currently logged in user.

Is there a recommended approach to this for the dev stream?

my apologies, i mis-read your terse questioning.

a 'blank' value is essentially undefined in database terms and may be
interpreted in various ways.  in a mysql database (and other relational
databases i know of) a 'blank integer' would generally be null.
however the value could also trigger a database condition that would
assign it a specific value which could in fact be defined as a custom
data type or enumerated value.  essentially, your question holds
limitless answers, none of which you could actually 'see' (unless you
wish to see an arbitary mnemonic or binary code).

in django 'blank' does not define the data type, or even a property
of the data it simply asserts that an empty (or blank) field submission
should be considered valid, or more accurately, not be considered
invalid within the admin interface.  i think of this as a common
override case in the standard validation code (which is most useful
for a text field).

Display of foreignkey relations

[Patricia P.]

Hello everybody, I need your help. I have the following data model:

class Contract (models.Model):
:

class Project (models.Model):
::
contract= models.ForeignKey( "Contract")

and would need to modify the administration interface that
automatically generates Django, in order to view in edit page contract
of admin the list for each of their projects. But I do not want to
edit them in the contract.
You should get something like:

Contract 1

  List of project
   Project A
   Project B

I hope your answers. Thanks in advance

Re: Your IDE of choice

[joeygartin]

Textmate with Python/Django bundles is very visually nice, but without
code completion (and a few other tools) is just a pretty screen.
Eclipse/PyDev would be nice, but it does seem to have a lot of little
issues that are annoying.  I have used IntelliJ for Java (and a couple
of Rails projects) for the last few years and am looking into the
Python/Django support for it.  If they bring this up to speed then it
should be the best IDE out there.

Posting the relevant code and the full traceback would have help...
Without this, my only guess is that there's something wrong in your
code that makes the decorator confusing your class __call__ method
with the request object.

One thing worth bearing in mind is that Django supports different
database backends.  Potentially, or ideally, it might even support
non-SQL databases, like hierarchical databases, or XML-based databases.

Revise "search code" in Django Book

[Bob]

Hello,

I am using the search code from the Django Book to search a
publication table (model).  The results are placed on the search.html
page.  I want to drill down and send more detail from the link that
now surrounds each of the search results.  I would like that detail
information to go to another page search_detail.html.  The ID from the
first search is associated with each publication link and that ID
should be able to retrieve the same information as the original
search, but let me expand on the info for one publication on a new
page.   I need assistance on either revising the original search
function in the view or fixing the  search_detail function instead.
The code is here:  http://dpaste.com/106510/.Can anyone help?

Thanks,

Bob

Re: Traceback in the ``runserver`` console

Hi Russ,

As I thank you for your quick reply I apologise for my lack thereof.

These approaches seem well suited (and surprisingly clean) for
achieving the desired functionality.  I think it will make sense to
suggest an improvement to the  `--traceback` switch, perhaps making a
patch if I have a brave moment sometime soon, and I appreciate the
encouragement.

Using cache_page decorator with callable cllasses

[Elton Okada]

Hello, I wish to use a callable class to anwser this URL:

urlpatterns = patterns('voduBBB.servicos.views',
(r'^participantes/$', ParticipanteView()),
)

It is OK.

Now I wish to cache the result of ParticipanteView() using this
decorator: @cache_page(60) at the __call__ method of this class.

But is fall in this error:
'ParticipanteView' object has no attribute 'method'

PS:
I have already set the attribute method in this class:
method = ''

"submit" and urls.py fail after moving site from runserver to Apache

[rabbi]

Hi,
I followed the django tutorial and got my site running on runserver +
sqlite3 with no problems

I then moved the site onto apache + mod_python and (after receiving
some help from this group) managed to get the same site semi-running

The admin page, home page, and a few others are working as they were
with runserver... but I now have a strange problem with one of my
pages

I have a submit input on one of my pages and when I run the site on
runserver it still works fine (I just tried it now)
However, when I run the exact same site on Apache the url that is
returned by "submit" is different, and this obviously causes the
pattern matching in urls.py to fail

Here is the html + template script that causes the problem

{% if error_message %}{{ error_message }}{%
endif %}


{% for entry in entry_list %}
{{ 
entry.eng_val }}

{% endfor %}



With runserver it returns the following when I press submit:
  "http://127.0.0.1:8000/swenglish/test/submit/;

With Apache it returns the followingwhen I press submit:
  "http://localhost/swenglish/test/submit/?thank
+you=tack=mycket=han=roligt=hej+da=sno"

Any help would be greatly appreciated!

Re: lighttpd + django on windows

[Eric Simorre]

In fact, I think that the chapter describing the fastcgi deployment in
the django doc is a little ... light :-)

it gives only a description of a typical django.fcgi, and that's all.

I have already deployed django sites with the following configs:

- fastcgi  ona hosting platform
- apache/mod_python
- standalone

and there was no problem.

With lighttpd, I thought (naively ?) that the deployement would be
light and easy and I am just disappointed to note that it is not true.

Could: probably, should: maybe, required to be: no.

By that reasoning it sounds like blank should not be a model field
parameter, since it only controls what is accepted in forms for the model,
not what is stored in the database.

blank simply controls whether the form field is required.  It doesn't say
anything about what's stored in the database, that's what null is for.
They're decoupled, which allows for setting blank=True,null=False and
substituting a non-blank auto-generated value at some point after form
validation but before saving the model.  It may not be an approach you
prefer, but that does not make it incorrect.

Customizing form fields display

[sagi s]

Can anyone suggest a way to customize model field display?

For example if I have a model called Course with fields n_girls and
n_students,

if for a particular record n_girls = 4 and n_students = 10, I want to
display for n_girls: "40% (4)" instead of just "4".

Obviously I can do this in the template but there are multiple fields
I want to customize and the lack of switch/elsif statement in the
templates would make for a deeply nested structure so I'd rather do it
upstream in the model.

Thanks in advance.

Sweet!

I've been looking (and I'm pretty sure it's not only me who's been

Luckily I use OS X at home, which probably means that I can use this

But that is code that could/should belong in the form/validation code.
The models define how things are to be setup and stored in the database
backend.

A blank value in a webpage does not translate to a blank value in the
database, so blank=True is incorrect in this case, as an auto-assigned
value isn't actually blank, because a non-blank value will be stored in
the database.

subquery has too many columns

[timc3]

I updated my django version to revision 9710 today and now I am
getting the following error message on screen:

Caught an exception while rendering: subquery has too many columns

This is the traceback:

ProgrammingError: subquery has too many columns


It seems that this query is creating the problem:

groupmembers = requestedgroup.group_members.exclude
(id__in=groupadmins)

And the model looks like this:

group_members = models.ManyToManyField(User, verbose_name="group
members", related_name="groupofumembers")



And ideas?

Re: Using a model method in ModelAdmin fieldsets

[EagerToUnderstand]

Thanks Karen & Daniel,

I think your overiding approach will work.  Thank you.

Implemented a work around.  I added extra fields (that persist my
method information) to my model that I update and save when I do a
listing.  Price I pay is an extra database update each time the model
is getting listed.
Will see how it influence performance.

Thank you for your replies.

How to impose a permission-based filter in admin?

[ZebZiggle]

Hi,

I have two Model classes:

class Opportunity(models.Model):
rep = models.ForeignKey(User)
 ...

class Deal(models.Model):
opportunity = models.ForeignKey(Opportunity)
 ...


I want to limit the admin UI so that users can only see Opportunities
and the related Deals they own. If they attempt to go into the Deal
table directly, again, they should only see their Deals.

To make it more interesting: Some users (that have a special
permission) should be able to see ALL Opportunities and Deals.

How can I do this?

Thx!

The change view pretty much focuses on displaying in a form only what you
can change in a model (non-editable fields are not displayed at all, for
example).  Since you can't edit/change something that is the result of a
model method, I don't believe there are any hooks for showing these thing on
the change page.  If I were to try to do this (which I haven't, so no
guarantees that this is even the right approach) I'd probably start by
looking at overriding/extending the template used for the change view for
that model:

If nobody responds with a pointer to a tutorial, you might want to provide a
few more details on what exactly you've done to set it up (versions,
commands run, whatever) and what "does not work" looks like, exactly.  I
know nothing of this particular setup, but without such details you are not
likely to get many helpful responses, even from people who have some
experience trying the same setup you are attempting.

That is, blank is not actually stored in the DB but rather the lack of a
user-provided value triggers creation of an auto-assigned value.

Re: Using a model method in ModelAdmin fieldsets

[EagerToUnderstand]

What I try to achieve:
I have a couple of model methods that exposes real time information.
(Retrieved when method is called.)  This is information I want to
display not only in the list_display, but also within the change view.
(Where the fieldsets come into play).

Since the list_display option support methods call I was wondering how
I can expose this information within the change view without too much
changing the default code.  I think the problem is that the change
view builds up a form from the model and method calls can not be
updated.  The reason why not included in the form object ..and
therefor not visible to the fieldsets field?

Still clear as mud?

Adding link to Django book Search code

[Bob]

Hello,

I would like to change the view so that the link retrieves more of the
detailed information from the same model publication, but I haven't
figured out how to change the view to respond either to a new search
and/or to more detailed information about the item found.  The link
can go to a new page or refresh on the current search.html page.  See
http://dpaste.com/106410/  for the html and the view.

The URL is:
urlpatterns = patterns('mysite.fsafety.views.',
(r'^$', 'index'),
(r'^search/$', 'search'),
)

Thank you for any help.

Bob

I'm interested in how a blank integer looks in a MySQL database. Can you
provide an example?

Not at all sure what you're hoping to achieve here. Fieldsets are for
groups of fields on the model edit page. How does a model method fit
into this? Can you show us some code?

As Karen says, logic in the class declaration is only executed once,
when the form is first imported. Authorlist and articletypelist are
much better implemented as class methods on the relevant models:

class Author(models.Model):
...
@classmethod
def get_authorlist(cls):
return [('choice%s' % a.id, '%s %s' % (a.first_name,
a.last_name))
 for a in cls.objects.all().order_by('last_name')]

Then in your view or template you can do Author.get_authorlist() to
return the up-to-date list.

However, a much better solution is to use ModelChoiceField for the
Articletype and Author fields. These populate the list dynamically
from a queryset:

class NewArticle(forms.Form):
...
Author = forms.ModelChoiceField(queryset=Author.objects.order_by
('last_name'))

Using a model method in ModelAdmin fieldsets

[EagerToUnderstand]

I am referencing a self defined model method in list_display option of
ModelAdmin.  I would like to do the same in the fiedsets option of
ModelAdmin, but I get an error saying my method is missing from the
form when the page is rendered.  It seems to me I can only render
model methods with list_display and not the fiedsets.

Any tips to get this working?

I agree with this. I use null=False, blank=True for some ImageFields
and integers. In both cases, I am generated the this content for the
database, but it is not entered. In the case of the ImageField, an
image is uploaded (an original), then I generate a thumbnail, and a
viewable (a standard sized image).  Technically at this point I don't
need blank=True here because users only upload the original image, but
at some point I can allow them to upload an optional thumbnail and
then use that if supplied or generate it if not.

In the case of an integer, I use it for order of the images. So if a
number is given for an image, it is used, otherwise auto assign the
order number.

I thought this was a common use case with Django.  So that is a -1 for
me.

Thanks,
John

Specified key was too long; max key length is 767 bytes

[Rama]

i have a model as below (please follow the red color lines)

  class NewsEntry(models.Model) :
  url = models.URLField(max_length=1024,db_index=True)
  title = models.CharField(max_length=1024)

-
  thereafter i ran
 python manage.py syncdb

   i am getting the following error
  Failed to install index for pystories.NewsEntry model: Specified key
was too long; max key length is 767 bytes

 
i understood that the problem is with max_length of the URL.
if i change it 255 everthing was going on fine.

 

But As per the requirement URL should  be of length 1024
so  what did is ?
1) kept the length to 1024
2) Executed the following command on database
CREATE  INDEX urlindex  ON  pystories_newsentry(url(255));


   Can i specify  the same thing  (i.e) creation of index on URL(255)
instead of 1024 in model class NewsEntry itself instead of going
   to database and running the command (CREATE  INDEX urlindex  ON
pystories_newsentry(url(255));) ?

Yes, the NewArticle form class is only loaded once, and then reused.  This
is standard Python behavior.  If you need to depend on data that may change
between the time the form class is loaded and a form instance is created,
you need to put the logic that retrieves and uses that data into an __init__
function.  The __init__ function will get called each time a NewArticle form
instance is created, rather than just once when the NewArticle code is
imported/loaded.

Re: Django: creating formset is very slow

[Kottiyath]

Hi,
   I was able to solve it.
   The issue was not with formsets, nor database.
   It was slow because request.POST was getting delayed - ranging from
3.5 seconds to 3+ minutes.
   I even tried having an assignment as follows:
x = request.POST
  and even that was taking 3seconds to 3 minutes.
  On going through the depths of wsgi code (yay, opensource), I found
the parsing is much slower in case on multipart messages - and I had
my http content-type and encoding as multipart.
  Since having files was a rare thing in my code, I modified the code
to encode as basic encoding unless files was present.
  Now, the same code - with 500 elements - take 0.7 seconds instead of
the earlier 117 seconds.

  Open source is amazing.

Regards
K

Re: Import models from CSV files?

[Keyton Weissinger]

Hey Victor,

I did the django-batchimport mentioned earlier. I think it will
address your need but is definitely aimed at XLS. However, it does
already handle duplicates (it will either update them or ignore them
based on setting). You can also specify a subset of model fields to
use to determine whether a given row represents a duplicate. This
allows for "batch update" too.

If you get into it and have any problems, drop me a note.

Problems with locale of dates queryset

[Stefan Tunsch]

Hi!

I'm trying to display a list of possible months in a queryset. I do so 
like this:

premonths = MyModel.objects.dates('date_published', 'month')
months = [m.strftime('%B') for m in premonths]

The problem is that months get displayed in english instead of spanish, 
which is what I want.

I have the following setting in my settings file, but it does not seem 
to do what I want:

LANGUAGE_CODE = 'es-ES'


I can indeed work out a solution doing something like this:

premonths = MyModel.objects.dates('date_published', 'month')
import locale
locale.setlocale(locale.LC_TIME, "sp")
months = [m.strftime('%B') for m in premonths]


But I guess I'm missing something here...


BTW, the problem of the wrong locale of dates is everywhere I use dates 
on my site, not only in this snippet.

Re: I just tried GEdit and failed

[alex.gay...@gmail.com]

Right now I use Gedit as my text editor(I don't use the terminal
plugin, I just keep a seperate terminal up), that being said here are
the plugins I use:

 * class browser
 * code comment
 * file browser pane
 * indent lines
 * Python indentation
 * smart spaces
 * snippets


depending on what your looking for I believe that there is a current
in development plugin to add auto completion.

A common way to check if an object is getting saved for the first time  
or not is to check if it has a pk. A newly created object won't have a  
pk until you call the super save() method, so you can put whatever  
operations you want to conduct inside an "if not obj.pk:" block. See  
if that does what you want...

I just tried GEdit and failed

I just tried GEdit on the basis of this thread to replace a very good
but slow Komodo.  GEdit is not good, or should I say, the plugins that
let it be a python dev environment are not good.  Perhaps I've
selected and incompatible set of plugins, because they started off
working somewhat decently, then syntax coloring was wrong for some
files as though it was detecting the wrong language and the class
browser turned blank,

A lot of the plugins don't look like they've been touched in a few
years so maybe they're unmaintained.

Could someone post a list of of GEdit plugins that create a good
django environment?

Check out the save_model() method that you can override in your
ModelAdmin class. You can add custom logic there.

Process file after upload

[dmishe]

Hey.

I have FielField in my model for user to upload ZIP-archives. I want
to unpack that zip, place some files in some dirs and delete it just
after user uploaded it in admin.

How can i do this? Model's save won't work because it gets called
everytime model is saved regardless of were the file uploaded again or
not. Custom storage/upload handler seems too complicated for this.

Re: Your IDE of choice

[Adam Stein]

I have omnicomplete working (haven't used it too much yet).  I have this
in my $HOME/.vimrc file:

--.vimrc--
if has("autocmd")
autocmd BufRead *.py set smartindent
\ cinwords=if,elif,else,for,while,try,except,finally,def,class

autocmd FileType python set omnifunc=pythoncomplete#Complete
autocmd FileType javascript set
omnifunc=javascriptcomplete#CompleteJS
autocmd FileType html set omnifunc=htmlcomplete#CompleteTags
autocmd FileType css set omnifunc=csscomplete#CompleteCSS
endif

" Allow  to be used instead of  like other IDE's do
" for auto-completion
inoremap  
--.vimrc--

All 'autocmd' lines should be single lines.

Also, I have vim starting automatically importing the Django db.  I have
a little script (below) that will automatically find my settings.py file
and start vim.  I do this by starting at the location of the file on the
vim command line and working upwards in the directory structure until I
find it:

--dvim--
#!/packages/bin/python

"""
Start vim for Django files
"""

import os
import sys

args = sys.argv

# Get our starting directory to look for the settings file.  If no
# filename is given, start in the current directory
if len(args) > 1:
# If multiple filenames are given on the command line, we assume
# the same Django settings apply to all
dir = os.path.realpath(os.path.dirname(args[1]))
else:
dir = os.path.realpath(".")

# Start looking for the settings file, going up one directory if we
# don't find it until we hit the top of the filesystem

while not os.path.exists(dir + "/settings.py"):
if dir == "/":
# We are as far as we can go and didn't find anything
dir = None
break

# Go up one directory
dir = os.path.dirname(dir)

if dir != None:
# Found the settings file
os.putenv("PYTHONPATH", os.path.dirname(dir))
os.putenv("DJANGO_SETTINGS_MODULE", os.path.basename(dir) +
".settings")

os.system("/packages/bin/vim '+python from django import db' " + \
  " ".join(args[1:]))
else:
raise IOError("Django settings file not found")

sys.exit(0)
--dvim--

I'm sure some lines are probably getting wrapped.

I only use Django on Unix/Linux so I'm guessing it would need some
tweaking for Windows.

Drop down list not seeing newly added record

[jeffhg58]

I have a 2 forms. One to add a new author and then another form for
Articles which has a drop down list to reference the authors. The
behavior I am seeing is that when I add a new author and then go to
the New Article form which references the author it does not display
the new record. Also, I put in some print statements in the New
Article form class and those statements are only executed when I go to
my home page.

Here are my code snippets

def welcome(request):

print 'in welcome'

if request.GET:
if request.GET.has_key( 'newarticle'):

print 'going to new article'

return HttpResponseRedirect( '/melsite/newarticle')
if request.GET.has_key( 'newauthor'):
print 'going to new author'

return HttpResponseRedirect( '/melsite/newauthor')
else:

print 'retrieving articles'

articles = Article.objects.filter
(type_index__type='Poem').order_by('title')

return render_to_response('stories/welcome.html', {'title':
'Poems', 'articles': articles})

def newarticle( request):

print 'in new article request'
from storyforms import NewArticle


if request.method == 'POST':
print 'in new article post'
new_data = request.POST.copy()
articleform = NewArticle(new_data)
if form.is_valid():
form.save( new_data)
articles = Article.objects.filter
(type_index__type='Poem').order_by('title')

return render_to_response('stories/welcome.html',
{'title': 'Poems', 'articles': articles})
else:
print 'in setting up new article'
#from storyforms import NewArticle
articleform = NewArticle()
print 'after setting up new article'
print 'rendering article'
return render_to_response('stories/add_story.html', {'form':
articleform})

class NewArticle( forms.Form):

articletypelist=[]
authorlist = []

print 'in new article class'

articletypes = ArticleType.objects.all().order_by( 'type')
articletypelist.append( selecttuple)
for articletype in articletypes:
choicestr = "choice%s" % str( articletype.id)
typetuple = choicestr, articletype.type
articletypelist.append( typetuple)
authors = Author.objects.all().order_by( 'last_name')
print 'authors in new article are ', authors
authorlist.append( selecttuple)
for author in authors:
choicestr = "choice%s" % str( author.id)
authorname = author.first_name + ' ' + author.last_name
authortuple = choicestr, authorname
authorlist.append( authortuple)

ArticleType = forms.ChoiceField( choices=articletypelist)
Author = forms.ChoiceField( choices=authorlist)
Title = forms.CharField()
Content = forms.CharField( widget=forms.Textarea)
print 'end of new article def'

Jeff

no chance of sample code but i would put the code in the upload
processing and simply instantiate objects with something like

if request.method == 'POST' :
while more_data() :
x = myModel()
( x.a, x.b, x.c, x.n ) = read_tuple()
x.save()

obviously there's a lot more code required there but it should give
an idea of one simple way to populate the DB from posted data.  i
believe valts also suggested doing it in batches (i.e. don't 'save()'
every object) to improve the performance.

personally, i wouldn't even use django for this, i'd just import the
CSV into a database, perform my processing (i.e. eliminate duplicates,
tidy the data, etc) and migrate the validated data to the django system
for reporting or management or whatever.

answer is yes for any field type that accepts an empty string as having
a meaning.  i currently use this for a couple of custom fields that
are autogenerated but can be set manually, if desired.  it could also
happen for innumerate other reasons.

or put more simply '-1' for me.

as i stated previously it seems unwise to speculate what may be needed,
particularly because the current distinction is clear and valid,
however, i would still be in favour of a change in conventions that
will hide this issue/oddity from most implementations.

Django internal tests and url reverse lookup

[aeby]

Hi all,

If I run manage.py test form my project, Django internal test are
executed as well.
If such a internal test uses a RequestContext, all template context
processors defined in settings.TEMPLATE_CONTEXT_PROCESSORS are loaded
by django.template.context.get_standard_processors().

If one of this (custom) template context processors uses
"django.core.urlresolvers.reverse()" for a reverse URL matching, there
will be no match for project specific URLs as this URL definitions
aren't loaded for Django internal tests.

How can this be fixed? Shouldn't load the test environment all the
project URL definitions?

Thanks and regards,
/Aeby

Looks like the problem is trying to access the m2m property before the
instance is saved
for the 1st time - no id means ManyToMany relations will fail. In
`save` you're
trying to access `parent` (should be called `parents` IMO, plural)
which is m2m
and trigger the error.

* You'll need to check if you have an id, if not, save it once to get
it. After that, calculate and
  save again (blah).

* You can't access `parent` like that, m2m behaves like a list,  so
you'll have to check members
  of that list - which is not clear how is going to be achieved. If
different parents have different levels
  which one will you use ?

* Another problem: If parent's level is changed, the children won't be
updated, potential mess

* Last thing: Treading this path might lead to recursion (item with
parents which have the
  item in their parent, or up the tree, as well), you might wanna
rethink this setup.

Indeed. It is assumed that the reader knows at least a couple things
about the web, programming, HTML, and the HTTP protocol !-)

Go to the project's home page. The first line of text contains the
brand (and main menu). The fifth line - which is the first _effective_
content of the page - says :
"Django is a high-level Python Web framework"

I may be a bit biased here, but as far as I'm concerned, this is
obvious enough.

Still on the project's home page:
"""
Template system

Use Django's powerful, extensible and designer-friendly template
language to separate design, content and Python code.
"""

Note that you have two strong hints there:
1/ python code
2/ separate

If that's not enough, following the 'template language' link, you land
on a documentation page that makes the whole point very clear:

"""
If you have a background in programming, or if you’re used to
languages like PHP which mix programming code directly into HTML,
you’ll want to bear in mind that the Django template system is not
simply Python embedded into HTML. This is by design: the template
system is meant to express presentation, not program logic.

The Django template system provides tags which function similarly to
some programming constructs – an if tag for boolean tests, a for tag
for looping, etc. – but these are not simply executed as the
corresponding Python code, and the template system will not execute
arbitrary Python expressions
"""


(snip other already documented things).

Now I don't mean there's no room for improvement, but what, you just
can't stack everything on the home page, can you ?-)

Obviously, yes !-)

That's just like asking if a working knowledge of Java is essential
for Strut, or if a working knowledge of PHP is essential for the Zend
Framework, or if a working knowledge of Ruby is essential for Ruby On
Rails (etc, insert your favorite language/web framework pair here...).

Then why don't you just use the reverse relationship ?
   related_listing_list = result_category.listing_set.all()

which you can as well call directly from within the template, so you
don't even need to code for it in the view...

Indeed. id(obj) is a builtin python function that returns the OID of
an object. Where do you thing this 'id' name came from ?

You're getting the exact result you asked for : a listing instance
which primary key has the value category_id.

> i do not know how may i access corresponding records from two tables.

That's explained in whole details in the online documentation. Go to
djangoproject.com, click the "documentation" link, then follow the
"models : accessing related objects" link.


If i was one of Django's doc writer, I'd probably start to despair.
Why spending so much _volunteer_ time writing a pretty good *and* well-
organized documentation when no one seems to bother reading it ?

Re: strip_tags in django admin issues

[ChrisL]

Alex - you are a legend. That's functioning perfectly. I've moved the
import line to the start of the file, but other than that used your
code and it's working a treat.

Thanks for the swift help Alex, and also Karen: together you've
clarified Django very clearly for me.

Re: Import models from CSV files?

[Valts Mazurs]

Hello,
If the file handling job is not too hard I would put the functionality in
model. Actually it depends on complexity, use cases and taste.
You can try writing the sample code by yourself :)

Re: wondering how to do something similar to save_model for inline.

[Timboy]

Good call on the ModelAdmin spot. (user contacted me by email to see
if I had a solution yet.)

I got the formset.save() from here:
http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#the-save-method
saying: "If your formset contains a ManyToManyField, you'll also need
to call formset.save_m2m() to ensure the many-to-many relationships
are saved properly."

Works now just had it in the wrong spot. thx!
