Re: Displaying attribute from foreign key in admin
> I also get an error when I try 'parent.name'.
Try just 'parent'. It will display whatever is coming out of your
model by default (in the __str__() or __unicode__() method). That will
probably do it for you, but you can access the other information if
you write a method for it:
class Child(model.models):
parent = ForeignKey(Parent)
def parent_name(self):
return str(self.parent.name)
class admin:
list_display('id', 'parent_name')

It sounds like you want 'unique_together'. That specifies tuples of
columns that are unique as a tuple amongst all the rows in the table. So
if
unique_together = [('first', 'second', 'third')]
Then for each tuple formed from the attributes ('first', 'second',
'third'), there can only be one occurrence in the table.
There is no default way in Django's ORM notation to say that 'first'
must be unique amongst itself and amongst the 'second' values, etc. That
would require adding a constraint using raw SQL.

Malcolm

two column unique index?
I have two columns in my database that must be, as a pair, unique throughout all the rows. Googling tells me I want a two column unique index. From the docs it looks like unique_together is what I want, but that looks like it makes the two columns unique from each other within the row. Is there a way to do what I want?

Thinking about the data constraints, it's really a many-to-many relation where each column in the intermediate table is unique. That is, a Person model is joined to itself with a many-to-many key via an intermediate database table that stores the pairs of ids of the related models. Each id is only allowed to appear once in that table. There's an extra constraint that anything appearing in the first column cannot appear in the second column (so you can't add John->Jane and Jane->John). Out of the box, you can't do this in Django. However, you can get very close and then add the additional database constraint manually using raw SQL. For example, you could create the many-to-many key manually, using the standard technique in [1]. Or you could wait for #6095 to land in trunk and use that eventually (which is mostly just syntactic sugar for the technique in [1], so don't let that block your development). You can then specify the unique constraint on the intermediate fields, but you will have to add the check constraint to enforce uniqueness between the columns manually.

No, I said the ordering of the tables, not the ordering of the columns. The order that Django creates the tables isn't necessarily going to be the order they are output by pg_dump. Also, if you add a new table to a database, is it possible the order of the tables as output by pg_dump will change? What I'm trying to get at here is that I think that a general solution needs to be much more aware of things than just the output. It needs to actually understand the output and known how to relate like things to like. For all the database backends it supports, and that's why it's harder than it looks.

Re: django searching/checking for user
Gotcha, sorry about that, didn't quite get what was being asked. You can do a full text search in your database or implement some external software for search. Also if you have a field that you want items to be alike for you can always bounce off the database for items like that. I have implemented various forms of search and am right now of the opinion that my sites won't have too many hits to justify bouncing my searches off of google or yahoo. Those might be too generic for you, you might need to look into writing some custom code, but searching through the text of one model to find something similar should be fairly easy especially if you don't mind using some database power. I can't say I know anything speficially Django to accomplish this, so you are probably going to have to look for something else. Anyone else have any ideas?

You can also just import the model itself from the other app and use
it directly. This works just fine as long as you don't need cross
references, i.e. app A importing app B importing app A.

Re: mod_python or fcgi

That mod_python can be a memory hog is a bit of a myth. Yes it does have a base level memory consumption which is a bit more than necessary, but complaints about mod_python being really fat actually stem mostly from having a Python installation that didn't provide a shared library for Python. Lack of a shared library results in Python static library being incorporated in mod_python Apache module. When that was then loaded, because address relocations had to be performed, it became process local memory, thus adding a few MB to size of process. If shared library for Python is correctly used, this doesn't occur. As a result, the per process memory requirements of mod_python and fastcgi aren't that much different when looked at in the greater scheme of things, in as much as your actual Django application is chewing up 40-60MB of memory where as mod_python and fastcgi will be a lot less than that. In other words, be more worried about how much memory your Django application is chewing up rather than the hosting mechanism. That all said, mod_wsgi is possibly a better choice than both. This is because in its mode where it works like mod_python it has less base level memory overhead than mod_python. On top of that it also supports a mode which gives similar properties to fastcgi. Thus mod_wsgi can do what both of these other systems do in the one package. The mod_wsgi package also has less performance overheads, although like with memory, the real bottleneck is your Django application, plus any database accesses. Other things you need to consider are whether you use Apache prefork or worker MPM. With prefork you will have a lot more instances of your fat Django application, thus overall memory usage is more. You should therefore look at whether your application is multithread safe and use worker MPM instead, or use mod_wsgi daemon mode with a single or small number of multithread processes.

I believe the only way is how you are doing it. now let me ask a
question why you need that? can't this be done in the controller? are
you updating the price total many times per call? why not do it all in
memory and then save ones? if you take all that out of the model and
into the controller (maybe even a function) you could do something
like this.
new_order = Order()
new_order.total = sum(new_order.items.all())
order.save()
or I'm missing something?

'dict' object has no attribute 'autoescape'
Hi,
A year or two ago I created a small web application in django. I've
now brought it out of retirement and am trying to get it up and
running with the latest svn trunk code. I realize there have been
many changes to django in the mean time, however, the error I am
getting just doesn't make sense to me. According to google, there is
a bug ticket which mentions this error message but I don't understand
what it is saying.
I get the following error when I try to go to a django based webpage:
AttributeError at /report/1/
'dict' object has no attribute 'autoescape'
(/report/1/ is a path I have set up with template, etc.)
If any one can make sense of the following errors, please take a look:
Environment:

What is the error? What do I need to start looking at?
If you are looking for an internship in the New York area, as long as
you are comfortable with databases, unix environment, python and
django, email me :) Your first job will be to get this running :)

Re: At what point does a model get its own app? Wigging as I try to adjust to the Django way.
There's nothing wrong with parceling out models across different apps.
And unless you're planning on distributing each app separately, don't
worry about cross-app dependencies.
In this case, I'd encourage you to--since you'll probably want to do
more than just book-related stuff with your people. (The same could be
said about the books.)
Another reason to have 2 apps for these models is overall growth of
models.py. The more code that's there, the harder it becomes to edit.
(I'm in the process of parceling out a bunch of models myself. Don't
give yourself that headache!)

At what point does a model get its own app? Wigging as I try to adjust to the Django way.
I'm working on a project which for the purposes of this conversation
we could say is about authors writing and sharing books.
My tendency is to want to make an app called "people" and an app
called "books," as these are two different models in my mind. A
person has certain attributes which would be defined in the "person"
model, and the book has certain attributes which would be defined in
the "book" model.
For some reason it's weirding me out to put these in the same app. I
think because seeing tables like people_book or books_person doesn't
feel right. I imagine something more like:
books_book
books_genre
people_person
people_group
people_person_contacts
But I need to make the link between the author (person) and the book.
In the django docs I see that you can easily make a foreign key by
referencing the model:
manufacturer = models.ForeignKey('production.Manufacturer')
...but it feels like maybe stepping outside the "django way."
I know there's no definitive answer, but at what point do you
typically decide that something belongs in it's own app? Is it
typical to dump everything into a single app?

Reusing a child block in an inherited template
Hi,
I'm wondering if the following is possible with django templates. I
would like to override a given parent block, while maintaining the
contents of it's child block:
base.html:
{% block firstblock %}
Bla bla bla
{% block secondblock %} ble ble ble {% endblock %}
{% endblock %}
inherited.html:
{% extends "base.html" %}
{% block firstblock %}
this is being overriden
{% block secondblock %} {{ block.super }} {% endblock %}
{% endblock %}
I have a case similar with this one, which is not working as I thought
it would ( {{ block.super }} is outputting nothing, instead of the
value from the parent template). Might I be doing something wrong or
is this the expected behavior?
thanks,
Filipe Correia

I want to incorporate this feature in the existing frontend, is there something in the newforms library that already covers some of this ? If not is it possible to put the ftp upload under the file selection box created by the newforms library. I've never heard of using an http form to handle an ftp file upload. If an http form can do it, you can have your templates spit it out. If you do end up doing ftp upload, django won't be what handles it, as it is run through your http server. are there any snippets around that show how to use the ftp upload from a webapplication ? I haven't even found anything that says how to do it with straight html. Good luck! Jeff Anderson signature.asc Description: OpenPGP digital signature
django searching/checking for user
i was wondering if there is django related solution for searching/ checking if user (django.contrib.auth + profile) exists or to retrieve similar results? so if i have: search_for = request.POST['search_for'] do i split search_for and basically do sql LIKE search through table fields or is there some other/better solution? what about pylucene/lucene or something similar? when to use simple sql search and when some search engine software?

Search with Stemming, Accents and Entities
I am implementing an academic publications database, and am looking for a search solution. I need at the very least Stemming and Accented Characters support (i.e.: searching for "alvarez" returns "álvarez" and v.v.). Some of the fields have a tinymce editor, so the data is stored with html entities. It would be very nice to be able to also search in these fields (i.e.: searching for 'alvarez' returns a record that contains 'lvarez'). Recommendations for apps or 3rd party engines or personal experience implementing something like this is very welcome.

Re: Best practices for sending bulk (+4000) mail in Django / Python
I haven't send near 8000 messages yet, but what I did was a
combination of what Malcom suggested. I setup a model to queue the
messages (pickled email.MIMEMultipart) with a priority, and a cron
that runs occasionally to dump N messages per mx domain over time so
the mailing trickles out. to the local mailserver that actually does
the sending. Since the connection to the local mailserver is done
once and messages are batched it should eliminate the overhead of
sending one by one.
Then for bounce detection, import from Mailman and let it check the
POP3 account of the sending account.
I was really surprised at how easy it was. Python has all of the mail
stuff build in, and Mailman adds the bounce detection just by
importing its module. My point is don't be afraid to roll your own
solution, its not hard at all. For example the pop3 check/bounce
detection which might seem complicated is just a few lines of code:
def check_pop3_bounces(server,user,password):
messages=[]
s=poplib.POP3(server)
s.user(user)
s.pass_(password)
resp, items, octets = s.list()
bounced=Set()
# items will be a list of 'MSG ID, SIZE'
for item in items:#[:5]:
id,size=item.split()
resp,text,octets = s.retr(id)
text = string.join(text, "\n")
file = StringIO.StringIO(text)
message=email.message_from_file(file)
addr=BouncerAPI.ScanMessages('somename',message)
s.dele(id) # delete it, we'll forward non-junk
if isinstance(addr,BouncerAPI._Stop):
pass # junk message
elif addr:
for a in addr:
bounced.add(a)
else:
valid_messages.append(message)

OK, so my first guess at what's going on is incorrect.
You're calculating distances from one geodetic point to another --
this means that the units for both points are in degrees. Typically,
the `distance` GeoQuerySet method returns values that are in the
coordinate system of the field (e.g., if my field is SRID=32140, then
the values returned are in meters because that is the unit used by the
coordinate system). However, this is undesirable for geodetic
coordinate systems because distances in units of degrees depend on
your location -- for example, take a look at the spacing of longitude
lines on a globe they get closer together at the poles and are
farthest apart at the equator. Having distances returned in degrees
is not optimal for humans who think in units of meters or miles which
stay the same no matter where you're at.
Thus, when using a geodetic coordinate system, such as WGS84 (the
default, aka SRID=4326), a spherical distance calculation method is
used instead which returns _meters_ (i.e., the PostGIS
`distance_spheroid` function is used instead of `distance`). The
large values may be due to the fact that they are large values to
begin with -- it is ~2,029,313 meters from Chicago to Salt Lake City.
At some point I wish the distance values would be `Distance` objects
rather than number values, but at this point it would require a lot of
internal hacking on internal Django ORM components I'll put off to
another day.
Just to be clear, there is only one PointField in the model, right? I
ask because GeoQuerySet methods operate, by default, on the first
geographic field encountered in the model -- if you have more than one
geographic field then you may have to explicitly specify it in the
first parameter (`qs = MyModel.objects.distance('point_field2',
pnt)`).
If you still think you're getting bogus values set up an example model
and data set that exhibit the problem so that I can examine more
closely.
> So now that you know more about my setup, how would I find the
> distance between two users in a model?
from django.contrib.gis.measure import D # `Distance` object.
qs = User.objects.distance(user1.point)
for u in qs:
print u, D(m=u.distance).mi # Printing out distance in miles.

That's a good link. Sticking with the projected vs. geographic topic,

Thanks, Malcolm. I want some features from queryset_refactor and some from newforms_admin, but none of them urgently (yet), so I think I'll work around the bug and wait. Looks like this is working in *most* cases (see below), and maybe simpler anyway: part1 = InventoryItem.objects.filter(product=self, onhand__gt=0) part2 = InventoryItem.objects.filter(product=self, inventory_date__range=(weekstart, thisdate), planned__gt=0, onhand__exact=0, received__exact=0) return itertools.chain(part1, part2) The itertools.chain works fine in situations where I just iterate thru the items. But in one case, I really need to return a queryset. (Tried turning the chain into a plain list, that did not work.) I'm experimenting (so far without success) with a bunch of ways to try to turn a chain into a queryset.

Not to mention that with that many messages, there are going to be errors -- some permanent, some transient. Django's email system isn't designed to be a mass mailer on that scale. It's a whole other class of problem. > Is there are better way to do mass emailing to our subscribers? One immediate possibility that jumps to mind is to set up some mailing list software. Django sends email to the mailing list address and it then goes out to everybody. You'll need to configure things so that other people cannot post to the list, etc, but that's just a matter of configuration. If you use mailman (written in Python; well tested in production settings), you could fairly easily write some code to synchronise the mailman subscription list with whatever database table you are currently using to store the subscribers, I suspect. Another possibility is to use some sort of queueing system or service so that the emails are inserted into the queue and then sent over an extended period of time.

This sounds like it would be really difficult (complex) to make it work correctly. The output from a database tool is going to include stuff that you don't necessarily care about (e.g. constraints that are auto-created with names in some cases), the table ordering may well be different, models don't necessarily include all the fields in a database table... there's a whole maze of things that could be different. I'm not sure that comparing the output of one tool with the output of an entirely different tool to check for differences is going to be a robust solution. I think your current approach is a lot safer, since you at least understand the expected differences.

Complex Q-object combinations on trunk do have a few problems (bugs). It
turns out to be quite hard to get all the combinations working
correctly. This is one of the areas that development of the
queryset-refactor branch has devoted a lot of time to fixing, so things
will improve in trunk very soon (or you can try out your code on the
branch).
Without spending too much time on it, though, it looks like your
intuition about how Q-objects should work is pretty much correct and the
SQL construction is just not behaving itself.

Malcolm

Re: Language code as part of URL
Panos, Thanks for the links. I checked the conversation and the blog post, by they address issues I've already solved. What I'm really struggling with is the reverse() problem and how to cleanly move the language activation logic from middleware (Django's default mechanism) to the URL resolver. Wrt the language_id/language-code choice, I went for language codes and haven't run into any performance problems. I didn't quite understand when a complex join involving the language code would be needed and how that would make any significant difference in performance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Show diff between fresh and running database schema
Hi, has some one a script to show the difference between the running database and one which get created by syncdb? Up to now, I used the output of sqlall before and after a model change. But it would be better to do the diff of the running database. Up to now I do it like this: pg_dump -s databasename > running.schema ./manage.py test myapp # Hit ctrl-c after test database was created. pg_dump -s test_databasename > test.schema diff test.schema running.schema Maybe something like this be implemented as new management command ...

Andrew, Thanks for your thoughts! > If the content is ultimately the same and you're simply offering > translations you don't want to put the language code before the > resource in the URL. Ie you don't want /fi/second/example/ because the > hierarchy implies that for a different country it's actually a > different object. My preferred approach for translations is /second/ > example,fi/ (comma seperated as outlined > inhttp://tools.ietf.org/html/rfc3986#page-23). > This says to users that they're viewing the same resource but in a > different language. I've previously read and understood the reasoning behind the comma approach. At that time I still chose the language code as URL prefix, mainly because I felt it offers better usability and clearer URLs. For my eyes the ,fi suffix resembles the annoying .php? foo=bar=123672436 cruft still seen on many sites. But I acknowledge that there's a problem in the hierarchy logic. Anyway, the comma suffix approach doesn't fit well with Django's stock language handling, either. Django assumes the language is set and stored in the session in a separate view, which redirects back to actual content. When the language code is part of the URL, no redirection is done and the language is set as part of URL parsing. It could be done in a middleware, but I don't like that approach since middleware is unaware of the URL hierarchy and differences in language code handling between parts of the hierarchy. I'll take a look at the discussion Panos pointed out and see if any silver bullets are presented there. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Largest django sites?
I think the key here is the fact that Django is very scalable. When something starts going wrong with your system, Django has the tools available to figure out where the bottle necks are and it is quite simple. In the past I have hit bottlenecks with mod_python. That was easy to fix by switching to Wsgi and optimizing my sites with memcached. I have also had issues with databases, which is easy enough to figure out what calls are the heaviest, cache them better and possibly replicate my databases when I have to. If you anticipate to build sites as large as the Washington Post and Pownce then you know that Django's code is very usable, modular when you need to customize and verbose when you need to debug. Right now there are a lot of options for frameworks, personally I have found nothing that matches the stability, features and customizable as Django. Also nothing beats python IMHO. The key is here, everyone doesn't have the same needs so you need to be prepared to optimize your own settings. The core Django code is sleek, simple and unassumptious and rightly so. The contrib apps you might find you'll need to customize a lot and Django makes that real easy to do. That isn't always the case with frameworks...

Re: Q query question
Replying to myself with more clues:
I see the problem:
For this filter statement:
items = InventoryItem.objects.filter(
Q(inventory_date__range=(weekstart, thisdate), received__exact=0)
|
Q(onhand__gt=0))
,,, the SQL generated looks like this:
SELECT
"orders_inventoryitem"."id","orders_inventoryitem"."producer_id","orders_inventoryitem"."product_id","orders_inventoryitem"."inventory_date","orders_inventoryitem"."planned","orders_inventoryitem"."received","orders_inventoryitem"."onhand"
FROM "orders_inventoryitem" WHERE
(("orders_inventoryitem"."inventory_date" BETWEEN 2008-04-21 AND
2008-04-23 OR "orders_inventoryitem"."received" = 0.00 OR
"orders_inventoryitem"."onhand" > 0.00)) ORDER BY
"orders_inventoryitem"."product_id" ASC,
"orders_inventoryitem"."producer_id" ASC,
"orders_inventoryitem"."inventory_date" ASC'}
So the SQL ORs all of the Q clauses, and does not separate the Q
clause that I thought should have been ANDed.
On the other hand, this single Q query properly generates ANDed
clauses:
items = InventoryItem.objects.filter(
Q(inventory_date__range=(weekstart, thisdate),
received__exact=0))
The SQL:
SELECT
"orders_inventoryitem"."id","orders_inventoryitem"."producer_id","orders_inventoryitem"."product_id","orders_inventoryitem"."inventory_date","orders_inventoryitem"."planned","orders_inventoryitem"."received","orders_inventoryitem"."onhand"
FROM "orders_inventoryitem" WHERE
("orders_inventoryitem"."inventory_date" BETWEEN 2008-04-21 AND
2008-04-23 AND "orders_inventoryitem"."received" = 0.00) ORDER BY
"orders_inventoryitem"."product_id" ASC,
"orders_inventoryitem"."producer_id" ASC,
"orders_inventoryitem"."inventory_date" ASC'}
So is the first generated SQL a bug? Or am I still missing
something?
(And still hunting for a better (or any clean) way to accomplish my
goal...)

Re: No module named views, Django tutorial

Quoted from the Django Tutorial: If your background is in PHP, you’re probably used to putting code under the Web server’s document root (in a place such as /var/www). With Django, you don’t do that. It’s not a good idea to put any of this Python code within your Web server’s document root, because it risks the possibility that people may be able to view your code over the Web. That’s not good for security.

Q query question
I'm trying to retrieve all Inventory Items whose onhand quantity is greater than zero, OR (whose date is within a specified range AND whose received quantity is zero). InventoryItems have three relevant fields for this query: onhand, inventory_date, and received. I currently have only 2 inventory items, only one of which matches the desired criteria. If I specify the following two separate queries, I get the correct results from each query: 1. items = InventoryItem.objects.filter(Q(onhand__gt=0) ) ...correctly returns an empty list (currenly no items have onhand quantities). 2. items = InventoryItem.objects.filter( Q(inventory_date__range=(weekstart, thisdate), received__exact=0)) ...correctly returns a list containing one item. If I put the clauses together like this: items = InventoryItem.objects.filter( Q(onhand__gt=0) | Q(inventory_date__range=(weekstart, thisdate), received__exact=0)) ...I do not get the expected result (one item), but rather 2 items, including one that violates both clauses. But if I put these clauses together like this (omitting the date range): items = InventoryItem.objects.filter( Q(onhand__gt=0) | Q(received__exact=0)) ...I get the correct result. So I assume I do not understand something about either this clause: Q(inventory_date__range=(weekstart, thisdate), received__exact=0) or how to combine it into a larger set of filter clauses with an OR. I thought it was ANDing the first part with the last part, and that is how it seems to act on its own. But it behaves differently when combined in a larger filter with an OR. So what am I missing? Or, is there a better way to accomplish my goal? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

FTP upload of files threw django
Hello All, I've been working on a quality control portal that uses some features of django. The application is now completely running but the upload of large data files is quit slow. I've been looking around how to speed things up and the only thing i saw was using ftp upload instead of the http file upload. I want to incorporate this feature in the existing frontend, is there something in the newforms library that already covers some of this ? If not is it possible to put the ftp upload under the file selection box created by the newforms library. are there any snippets around that show how to use the ftp upload from a webapplication ? Any help or pointers in the right direction would be greatly appreciated.

Firstly, that type of information is often commercially confidential. Secondly (and more importantly for your case), "large" isn't a well-defined term. Performance depends on things like database size (the number of records that are accessed to produce the pages), number of different sorts of pages (which affects cachability), number of page views, number of active users (if you're doing per-user customisation) and probably a bunch of other things I can't think of off the top of my head. There are known examples of sites doing thousands of page views per minute, other sites with users in the hundreds of thousands and possibly more and yet other sites querying many gigabytes of data. At those levels, you have to put some effort into performance, no matter what you are using, but no problem is insurmountable. Keep an eye on performance as you are developing, don't prematurely optimise, since many decisions require the functionality to be known first, but do be prepared to try out a few alternatives in various situations. If you have concrete performance problems, feel free to post a description of the type of problem here. Best to have some measurements to hand first, though, since optimisation is rarely productive when you have to guess as to the significance of any particular feature.

Avoiding the ThreadLocals hack - anything new in NewForms-Admin?
I was reading this page http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser and was wondering how the advice on avoiding the hack applied to my own use case. I am using the ThreadLocals hack to get the current user in a model when overriding the save() method. Therefore I can't pass in the user as I can't control how save() is called. On a higher level my goal is to limit the Admin changelist to only show the objects associated with the current user. I am using NewForms-Admin so was hoping that there are new ways to achieve this but after a bit of head scratching and source-code reading nothing has leapt out at me. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Largest django sites?
May you enumerate the largest django sites (apart from WSJ)? Do you know traffic stats of these sites? I'm building a big site, with potentially lots of traffic and I'm a bit afraid what I can expect...

filtering in ModelChoices not working
hi,
this is my code snippet:
class Ingredientrecform(forms.ModelForm):
"""
Form to add Ingredients.
"""
def __init__(self,pageid, *args, **kwargs):
super(Ingredientrecform, self).__init__(*args, **kwargs)
self.pageid = pageid
ingredient = forms.ModelChoiceField
(queryset=Ingredient.objects.extra(
where=["""id not in (select ingredient_id from
web_recipeingredient\
where recipe_id = %s)""" % self.pageid]))
class Meta:
model = Recipeingredient
exclude = ('rank','recipe')
the problem is that all the ingredients get displayed in the choice
dropdown and not only the ingredients that pass the test in the
queryset. Where am I going wrong?
