runserver at the same ip address and port number doesn't report error

[fyaqq]

I tried to start the development server with the same ip address and
port number twice.
I supposed to see the second one fail with an error message like port
number already in use.
But I didn't see it and there is no error message.

Can someone tell me what's the reason behind this?

Thanks a lot.

model name ending with an 's'

hi,

I have a model named 'Services'. I added it to the admin page and an extra
's' was appended to the name (see attached file).
I grep'd through my project directory and I'm pretty sure that there are no
text that matches 'Servicess'.
So, is django the one altering the model name? If so, is there a way to

thanks.

Re: Decouple URLs and get_absolute_url issue

[grant neale]

Answering myself.

I knew it was something pathetic and I found it:

This is what I was doing wrong
(r'^weblog/'$, include('coltrane.urls.entries')),

This is what I should have been doing right
(r'^weblog/', include('coltrane.urls.entries')),

The dollar sign cuts of anything that I was including in the "entries"  
file.

Hope that may help some other bastd like me.

Re: looking for a clean, easy way to force user to change password on first login

[Shawn Milochik]

This isn't ideal, but it should work (or prompt someone to propose  
something better).

Add a one-to-one table for the user, with a field containing the  
initial password (encrypted, of course, so it looks like the password  
in the auth_user table).

When the user logs in, have the login page check to see if the  
passwords match. If they do, redirect to the password change page  
instead of the normal redirect page.

I think you still have to pass the user, but you can tell if the item

Re: how to alter (add/del cols) the tables from the existing models

[Shawn Milochik]

Look at south or evolution. I use south, personally. It does exactly  
this very easily.

http://south.aeracode.org/wiki/Tutorial1

To add a column to the database with south, you add it to the model,  
then:

./manage.py startmigration appname migration_name --add-field  
model.field

So, if your app was named awesome, and you added field thumb to model  
Hand, it would look like this:

./manage.py startmigration awesome added_thumb --add-field Hand.thumb

then:

./manage.py migrate

Of course, check out the tutorial.

There is probably a way to do this if you dig deep enough into the  
Django code, but the admin wasn't meant for this. According to the  
second edition of "The Definitive Guide," the admin was meant to be an  
easier-to-use and less-powerful replacement for the command-line  
interface to your database. If you are developing in an environment  
where the content creators are trusted to have this kind of access,  
then it's an added convenience.

Creating forms and modelforms is simple, and have the added benefit of  
being much easier to control layout.

Your views could get the request.user.country and use that as an  
automatic filter.

The short answer to part one is "yes," because you can customize  
everything in Django. However, I don't know if it's trivial to modify  
the admin in that way, and that's really not the kind of thing the  
admin was intended for. You should probably just make a form for this  
functionality. It would take about a minute, and the view wouldn't  
take much longer.

For the second part, certainly. Just override the save function of the  
model. If the object already has a primary key, then don't save those  
fields. There may be a more elegant way to check whether it's already  
been saved than checking the instance.id, so maybe someone else will  
chime in.

I must have been unclear: The two questions are unrelated. I want to
know how to access the verbose_name for a model within the Python
code, not the template.

I have a function that takes in a model, and I want to get that
model's verbose_name (or plural, or some other Meta property). Is
there a way to do this other than model._meta.verbose_name?

Yes. In fact, I only discovered that this was a problem when I
switched to the subversion from 1.02 recently and had the site fail to
work. It has been working fine on Webfaction's 1.02 for more than a
month with me accessing a protected variable (double underscore, I
believe).

Hmm...Tried it for another object, and it isn't working as well with
1.02. I'm 100% sure it worked for something else I was doing - but I
don't want to go through the trouble of duplicating it because I
changed quite a bit of the system to get it working with subversion
and it's probably not worth the bother. Probably an obscure bug.

Oh what the heck. Looked through my logs and managed to duplicate:

You're right, stuff like {{ object.__str__ }} doesn't work in either.
However, in 1.02, the following works:

{% ifequal object.__str__  some_string %}
Look ma! It works!
{% endifequal %}

whereas I get an exception in subversion. I don't know if that's just
for ifequal or whether it'll occur with {% if %} and others, as well.

(And I don't recall whether the match actually worked or not - but
that's another story).

Since it fails under SVN, I'm assuming it was caught and fixed. I
haven't looked at the Incompatibility list to see if it's there.

Anyway, though, what's the rationale for not allowing double
underscored properties? I know single underscores are considered poor
practice, but I don't recall that accessing the double underscore
properties as being discouraged. After all, people do it all the time
in Python, and I'm sure Django's source makes heavy use of it...

Just make a forms.ModelForm for your Book model. The class Meta will  
contain 'model = Book.' You don't need any of that inline stuff to  
edit a single instance.

Briefly (assuming your ModelForm is named BookForm):

In your view, you will make an instance of your ModelForm:

book_form = BookForm()

Then do the typical render_to_response bit.

You will also have an if request.POST in your view. If that's hit,  
then you will declare your form like this:

book_form = BookForm(request.POST) #if you're not doing a  
request.POST.copy(), which you probably should.

Then: if book_form.is_valid(), you save it. If not, you let it fall  
out of that if statement into your render_to_response part.

Make sure that if the form doesn't validate, you're not doing the  
"bare" book_form = BookForm() and overwriting your bound version. The  
bare version could be above the if, or in an else clause.

To the best of my knowledge, you have _never_ been able to access
'protected and private' attributes(i.e., attributes starting with _)
in a template. Are you certain you were able to do this in the past?

If this is true, it would be a major backwards incompatibility, and
one that we will need to fix. However, I'm not aware of any changes
that have been made to the template system since v1.0 was released -
certainly none that would make this change.

Can you provide specifics of the Django versions that you believe
allowed this behaviour, and the earliest version in which you are
aware that it was removed?

You're not the first to suggest the idea. There are two (well, three)
obstacles that are standing in the way of this idea:

Firstly - What's the interface to this? Is it just an extension of the
capabilities of select_related? If so - how does the proposed
interface map to SQL? In particular, what happens to the results in A
that are duplicated when you do a select_related() onto B?

Second - How do we constrain the performance implications? For
example, if a table with just 3 rows does a select_related() on a
table that contains 1 rows, how do you prevent an query
accidentally bringing the system to it's knees?

Third - someone needs to actually write the code. However, this is a
non-issue until the first two are resolved.

The reason select_related() has been implemented for the N-1 case, but
not the 1-N case is that the answer to the first two questions is
easy. Since the relationship has cardinality 1, all you're doing is
extending the result line. There's no need to worry about handling of
repeated results; performance problems are limited to concerns of the
depth that select_related will traverse.

If you have any particularly inspired answers to these questions for
the 1-N case, feel free to let us know. We're always interested in
making Django better.

You're correct that there isn't any explicit support for cache
flushing in the Django cache API. However, you can manually flush the
cache - the technique just depends on the cache backend you are using.
In most cases, you will be able to fall back to the capabilities of
the underlying cache implementation. For example, to flush memcache,
you can use the capabilities of the underlying cache object:

from django.core.cache import cache
cache._cache.flush_all()

If you're using locmem, you can just reset the dictionary in the cache object:

from django.core.cache import cache
self._cache = {}

Analogous solutions will exist for the other backends.

Another possibility is to use the dummy cache for testing - that is,
use the cache backend that doesn't actually cache. This will ensure
that you don't get any caching effects in your code. Of course, this
doesn't help if you're actually trying to test the caching behaviour.

However, your original point is valid. Caching is one of those things
that needs to be reset for testing purposes. It makes sense for
Django's cache backend to expose a flushing capability, and Django's
TestCase should be using these facilities. Please open a ticket to
make sure this idea isn't lost. If you take a swing at a patch (and
tests), I'll see about getting it into trunk in the v1.2 timeframe.

The current_app argument was added as part of the fix for reversing
admin URLs. The argument is definitely available to both Context and
RequestContext. If your code is raising errors when you pass
current_app='xxx' to RequestContext, then your Django checkout isn't
completely up to date.

To confirm - line 100 of django/template/context.py is the definition
of RequestContext. It should read:

def __init__(self, request, dict=None, processors=None, current_app=None):
Context.__init__(self, dict, current_app=current_app)

Re: Expert System

[Joshua Russo]

I second that. In my experience they are inherently very context specific,
with very unique databases and code bases. With that said, you
can definitely develop an expert system using django. It's more about
the algorithms you produce than the environment you produce them in.

How can I do per-connection initialization using connection_created?

[gthank]

It's not clear to me how I can execute a statement on the newly
created connection when the sender is the wrapper class, not the
connection I want to initialize. I reopened 
http://code.djangoproject.com/ticket/6064
since the final implementation doesn't seem to address the original
problem, but was told this is a better place.

The reason I am trying to do this is so I can implement multitenancy
using a schema-per-client solution in Postgres. If there is a better
way to do that than initializing each connection a request creates,
I'd be glad to look into that.

Thanks,

Hank

looking for a clean, easy way to force user to change password on first login

[pjv]

i am working on a project where i need to create a number of users
(standard django User objects who will login to the site using the
vanilla django auth framework) along with random passwords (rather
than allowing the users to sign up and supply their own passwords).
after the site launches, staff will email each user their username and
the generated random password and a link to the site.

ideally, the random password would be a one-time password and when the
user logs in, they would be automatically redirected to the change
password page and required to pick a new password.

i've thought about creating a special link to put into the email that
would hit a view that redirected to the change password view rather
than the usual home page after login, but that seems a little kludgy
and also easy to get around since the user might not use the link from
the email.

i've done a fair amount of googling and struck out. i don't want to
reinvent the wheel here, or write a bunch of code if i don't have to.
anyone have any ideas or pointers to prior art?

Flushing the cache during testing

[Andrew Fong]

I'm playing around with some low-level caching of model instances.
During testing, it's necessary for me to flush out the cache so cached
whatnot from one test doesn't pollute another.

To my knowledge, Django's currently doesn't offer support for
resetting the cache after each testcase in the same way it does for
the test database (via the custom testcase class).

The options I'm looking at:
> Manually (re)starting a separate cache process
> Adding a prefix to my cache keys and changing them for each test case

Ideally, I'd just like to flush the cache but after poking around in
Django's caching code, I haven't seen any explicit support for
flushing. Does anyone have any ideas?

Try fetching the data via Django's shell. What do you get then?

Also, how did you configure MySQL to work with UTF-8? Did you modify

I'm not sure if this will help but try adding {{ block.super}}

Try reverse('admin:index ')

The colon is the new namespaces that were just added to the django
urlresolvers. Pretty exciting, huh?

FYI the admin uses 'admin' as the default app instance. I am not sure what
this will do if you have two apps that are named the same and try to
reverse. It might just be unpredictable as to which URL is going to be
returned or might throw an error. I am not sure. You might want to change
that to something else.

Hope that helps,

I can help you with that - you shouldn't do that.   Instead you should
create a new model for friends and link users to friends with a one-to-many
relation.  Each friend can have a single character field for their name,
which will give you a list of strings (friends) attached to each user.

Does that make sense?

docs. I changed the initialization of my admin site so it doesn't have
a name and what I was trying to do works now. But anyway, if my admin
site was initialized like so site = MyAdminSite('admin') what code is
supposed to give me the url for it's index page?

Re: A question about reverse url lookups for admin site in svn version

[Vasil Vangelovski]

Yes it does work, I've tried this with a brand new project in the same
virtualenv. Reverese resolution of urls for the AdminSite in
django.contrib.admin does work with the latest trunk revision.
Here's simplest situation where I'm having a problem:

I have an app called admin in my project which contains some
templatetags and a subcalss of AdminSite, you can see the relevant
code in this dpaste:
http://dpaste.com/68309/
The shell interaction is here:
http://dpaste.com/68303/
Note in my installed apps I have both my admin application and the
admin app from django.contrib.
The same shell interaction would work without a problem if I try it in
another project where I use just django.contrib.admin.sites.AdminSite
Note that changing the url regex for the admin from empty to
r'^admin/' doesn't change anything, it's like that because the django
project
is just an admin site for a larger project done in Java/Flex.
Thanks.

Re: accessing multiple dbs?

[Richard E. Cooke]

Thanks for the replies!

Happily I have managed to avoid the issue.  We will just make one
Django site per database.  Using a web page to post all the different
sites, thus making it "look" like its accessing multiple dbs..

Cheap shot I know, but I'm very lazy.

Plus I figure by the time I really get forced to deal with this issue,
GSOC will have helped out enough it won't be "hard" or tricky
anymore

By the way,when I was evaluating different packages to choose I was
torn between Django and TurboGears2.  It was the fact Django has GSOC
working on the multi-DB issue that made me choose it.

Well I'll build it for you for $15 million.

Maybe a lot, maybe a little. Depends on the developers the traffic,
licenses you might need. This isn't the right place to ask a question
like this. We take months to write up a detailed proposal of costs.
Given that everyone here is volunteer and working on the same thing, I
doubt they are going to build a business plan for you.

We can help with specifics, but given that Django itself is free (as
in beer) costs are up to you.

Howto add button to certain field

[zayatzz]

Hello

I have this form with username and other user information. Since user
needs to set his own username and it has to be unique, i was going to
add some button to the form that does some ajax magic and checks if
the username is already in use.

What i wanted to know is that if there is some way to add this buttong
right next to the username field through the way how the form itself
is set up - (widget?). I know that i can of course ditch this :
{% for field in aform %}
{{ field.label_tag }}
{{ field }}
{% endfor %}

And write all that markup without for loop and just add the button
after usename field. What i wanted to know was if it can be done
differently?

Thanks Michael.

Look into the apache log, I see that when the login page is accessed 
again, it returns 304, then the subsequent submit returns 403.

116.22.69.90 - - [17/Jul/2009:23:12:06 +0800] "GET /accounts/login/ 
HTTP/1.0" 304
116.22.69.90 - - [17/Jul/2009:23:12:17 +0800] "POST /accounts/login/ 
HTTP/1.0" 403 159

I guess there are some tags that apache or mod_python omits. But I am 
not sure. I will do more research soon.

pre-fetch one-to-many and many-to-many relationships

[Miriam]

There currently is no way in Django to pre-fetch one-to-many and/or
many-to-many relationships, right?

There's select_related, which will pre-fetch FK or one-to-one, which
is great, but not sufficient.

Suppose I am fetching a list of Blog posts and I want to pre-fetch the
Comments for each of these posts? There's no way to do that in
Django.

I was looking through the tickets at code.djangoproject.com and I
didn't see anything about this.

Does anyone know if this feature is planned for sometime down the
road? Anyone have a work-around or a patch or anything. This is
supremely irritating.

I can confirm they work, but they were only checked in less than 48 hours
ago, so I would first double check and make sure you have the newest version
of the django svn. If you are all updated and it still doesn't work, posting
your admin site, model admin and where the urlreversing is happening, we can
help you.

Also, sometimes you can get a more helpful error message from the shell. The
reverse() function that you can use is available in
django.core.urlresolvers.

Let us know how it is going,

Michael

I have encountered this, but it isn't a problem with the admin, it is a
problem with the browser. These pages are stored for offline use and then
when the user goes to the page, they don't get a new token. You can see here
[1] and here [2] where the views are cached. You can look at your browser
and see that the headers are right as well. You should see something along
these lines in the headers: Cache-Control max-age=0

1]
http://code.djangoproject.com/browser/django/trunk/django/contrib/admin/sites.py#L324
2]
http://code.djangoproject.com/browser/django/trunk/django/contrib/admin/sites.py#L188

I haven't been able to figure out how to fix this behavior in the browser,
but the user only needs to refresh a few times to break that cache.

I would love to hear if anyone else has figured something out to fix this.

Also if you are using the 1.1 branch, make sure you update svn there was a
recent fix put in for caching of all pages[3], but otherwise, the best I can
tell, this is a browser issue, and not something Django can easily fix.

A question about reverse url lookups for admin site in svn version

I'm using svn trunk version of django (rev. #11263). In my project I
have only one admin site registered in the urlconf. This admin site is
a subcalss of django.contrib.admin.sites.AdminSite and is instantiated
with the name 'admin'. I'm trying to use reverse url lookups for the
admin site as described in the docs:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#admin-reverse-urls
But it doesn't work, I always get a NoReverseMatch exception.
Can someone confirm that reverse url lookups for admin sites work as
described in the docs with the latest trunk revision?

Yes, I bumped into the same problem and came to the same conclusion. No
way. Unless you hack out something along the lines of
translation.activate/get_language - using a global dictionary and 
current thread. It works, but is hardly in line with Django spirit.

I think it is a design decision, to keep MVC structure clean. Though it 
might be arguable if it would really seriously breach the MVC principle. 
Maybe it is worthwhile.

never_cache doesn't work for login page

[Ronghui Yu]

Hi, All,

I have a project that have CsrfMiddleware enable, all forms work fine,
but the login form doesn't, for all browsers(IE,Chrome,Firefox,Safari).
Most of the time, it throws 403, which is thrown by CsrfMiddleware.
That's because the browser cache the login page, so each time the login
page is opened, the csrfmiddlearetoken value doesn't get update. If the
browser cache is cleaned before opening the login page, then it works
fine. But this is not what I expect.

When look into django.contrib.auth.views, the login view is decorated by
never_cache, but actually it doesn't work for me. I have no idea what's
wrong with it. Has anybody ever encounted this situation? Or could
anybody give me some hints?

Thanks in advance.

Remember that "manage.py syncdb" only check if the table exits/not
exits, it doesn't check structures. So if all the model is in the
server, syncdb simply do nothing.

I'm pretty new in Django, but i think that you need to make that
change manually in the database server, i mean: change the model
(adding the field) and change the structure of the table (adding the
field with the same characteristics).

Another option is to backup your data, drop all the tables, do
"manage.py syncdb" and recover the backup.

Overriding admin forms

[cornjuliox]

Hi everyone. I'm new to Django, learning things mostly through trial
and error, but this time I can't seem to figure out what went wrong. I
overrode the admin change_form.html for my model so that I could add a
Javascript RTE that I found, but not only does the text area look
broken (it's split in two, on separate lines), the slug field no
longer prepopulates (it did before I changed things). The RTE works as
expected, though. I'm not sure what I'm supposed to be pasting in
order to get an accurate diagnosis, so here's everything I think is
relevant.

This is the model in question:
class Entry(models.Model):
# ALL TITLES MUST BE UNIQUE! The slug is gonna give me problems if
it isn't.
title = models.CharField(max_length=250, unique=True)
slug = models.SlugField(
help_text="This field will be filled in automatically based on
the title field.\
  You don't need to fill this in. Honest."
)
subject = models.CharField(max_length=140)
category = models.ManyToManyField(Category)
author = models.ForeignKey(User)
dateTime = models.DateTimeField(default=datetime.datetime.now)
content = models.TextField()
content_html = models.TextField()

class Meta:
ordering = ['-dateTime']
verbose_name_plural = "Entries"

def __unicode__(self):
return self.title

def get_aboslute_url(self):
return "/%s/%s" % (self.dateTime.strftime("%Y/%b/%d").lower
(),self.slug)

def save(self):
html_data = markdown.markdown(self.content)
super(Entry, self).save()

This is the modeladmin for the model:
class EntryAdmin(admin.ModelAdmin):
fields = ('title', 'subject', 'slug', 'dateTime', 'category',
'content',)
prepopulated_fields = {'slug' : ('title',)}
date_hierarchy = 'dateTime'
list_filter = ('dateTime',)

def save_model(self, request, object, form, change):
if not change:
object.author = request.user
object.save()


And this is the new form:
{% extends "admin/change_form.html" %}
{% block form_top %}
A customized entry form.
{% endblock %}

{% block extrahead %}
http://js.nicedit.com/nicEdit-latest.js"; type="text/
javascript">
bkLib.onDomLoaded
(nicEditors.allTextAreas);
{% endblock %}

I placed this file in my templates dir, in the /admin/(my_app)/Entry
folder. Any help would be greatly appreciated, because I'm really
stuck on this one.

how to alter (add/del cols) the tables from the existing models

[Lokesh]

Hi,

Initially the table created with the following code
Class user_privileges(models.Model):
user_id = models.ForeignKey(User)
is_deleted= models.CharField(null=False, blank=False,
max_length=1)
is_email_active = models.CharField(null=False, blank=False,
max_length=1)

Now I would like to add the one more column to the "user_privileges"
model
is_phone_active = models.CharField(null=False, blank=False,
max_length=1)

The changes are not taken place when I do the "manage.py syncdb" after
adding the new column into the model.

Please guide me how do I modify the models after the initial creation.

I am not supposed to drop the "user_privileges" table because this is
linked to other tables as foreign key.

Thanks in advance.

Accessing Meta properties and a templating question.

[Beetle B.]

Hi,

1. In the Python code, how can I access various Meta properties of a
model (e.g. verbose_name, etc). At the moment, I do it via
model._meta.verbose_name, but I always get chills down my spine when I
access properties beginning with a single underscore. Is there a
"proper" way?

2. Can someone explain the rationale behind not allowing access to
properties of objects that begin with double underscores in the
template? It worked in 1.02, but with SVN I can't access anything like
object.__class__. I'm merely curious as to why this was restricted. In
one or two cases, life was easier for me when I could do it.

Thanks,

Re: How redirect lightweight webserver messages?

Yes and also on windows. I use tee in order to have print on stdout and also
on a log file. The problem is that I don't see django web server messages on

checking
Django source. Server log message are send to stderr (stdout is set as a

but tee logs only stdout.

Using AVG

[The Danny Bos]

Heya,

If I wanted to get the Average of all ratings (in a Rating table) for
a single record.
Would I use something like this:

ratings_avg = Rating.objects.aggregate(Avg('rating'))

And where does this live? In models.py or views.py and how is it
called.
I've been reading a lot about it, but some things seem implied which
I'm having trouble wrapping my head around.

Re: How redirect lightweight webserver messages?

That would depend on the OS you use.

If you use linux:  "python manage.py runserver >> example.log"
That will save the output in a file, instead of showing it on screen,
allowing you to have another webserver serve it.

Amazon Product Advertising API

[Luke Seelenbinder]

I'm working on a django project right now that uses the Amazon Product
Advertising API. I was using pyaws, but it is quite outdated and won't
be useful for the changes coming in the next month.

My first question is whether you know of any other python library for
it.
Second question, is there anybody willing to help me develop a new
python abstraction for the api.

I'm going to get started today with a new python api, if there is
anybody willing to help, drop me an email (lukeqsee at gmail), or just
reply to this message.

Thanks,

order = models.IntegerField(blank = True, null = True)
photo_item = models.ForeignKey('Photo', related_name='photoitem')
photo_item_name = str(photo_item.img)

how can i relate to 'img' attribute of 'Photo' class in
'PhotoSetPhotoItem' class?

why is this not working?
photo_item_name = str(photo_item.img)

tnx!

Doctests for custom template tags

[A Khodyrev]

  Hello

I'm writing a library of helper classes/functions to ease creation of
custom template tags. So a natural doctest (or an example in the
documentation) goes like this: define a compiler function and Node
class with my helpers, register them with a tag library, define a
bunch of template strings with these tags, then render these templates
and check whether the output is ok. However, there is a problem. For
this to work, I need to somehow tell my templates where to find the
tags. I can not use the {% load %} tag (because the tags being tested
are not in a module), so I need to somehow tell the Template object
where to look. I looked through django.template and there seems to be
no way to do that (libraries are added to the template's Parser object
which is deeply incapsulated).

So, my question is: how do people test such things?

Limiting administration based on user settings

[Rune Bromer]

Hello.

For a small webshop I have the following models: Product, Category,
Country and UserProfile. Each user have a country set with a FK, and
should only be allowed to see content in the administration assigned
to the same Country. The Product and Category have FKs to the Country
model so I can ensure this by writing a "formfield_for_foreignkey" on
the ModelAdmin. So far so good, as I can also filter the admin list
view by overwriting the queryset() model on the ModelAdmin.

The problem now is that I can assign several categories to each
Product. But I only want to allow people to see the Categories for the
same Country as the product. How is that possible. Apparently the
options for the m2m field is not filtered by the queryset and I can't
see there is a formfield_for_manytomanyfield?

When you create a relationship from model A (GameClaim) to model B
(User), Django automatically adds to model B isntances Python attribute
(the ' accessors'  above) that allow you to in case you have one B instance,
to get all the A instances related to it (in your example, using the claimer FK,
it would allow you to, starting from an given user, obtain all the
games she/he claimed).

The name of such an accessor is, by default, determined by a simple
rule: the A name lowercased and suffixed with '_set' (gameclaim_set).

The problem in your case is a typical one and the model validation error
messages you are getting are pointing you in the right direction: you have
two FKs between A and B and then the default names for the accessors
Django is trying to add clash.

Is In those cases when the related_name parameter of the ForeignKey
field is useful because it allows you to override the default accessor
name 'gameclaim_set'.

Read the relevant documentation for more details:

http://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey
http://docs.djangoproject.com/en/dev/topics/db/queries/#backwards-related-objects

Accessor for field clashes with related field

[Oleg Oltar]

Hi!


I want to create an object that contains 2 links to users. For example

class GameClaim(models.Model):
target = models.ForeignKey(User)
claimer = models.ForeignKey(User)
isAccepted = models.BooleanField()

but I am getting an error when running server:

Accessor for field 'target' clashes with related field 'User.gameclaim_set'.
Add a related_name argument to the definition for 'target'.
Accessor for field 'claimer' clashes with related field
'User.gameclaim_set'. Add a related_name argument to the definition for
'claimer'.

Please explain why I am getting the error and how to fix it?

Thanks,

Decouple URLs and get_absolute_url issue

[grant neale]

Hi,

I'm going through James Bennet's Practical Django projects.

When I de-couple the urls to "urls folder" + "url category"  I  
get_absolute_url doesn't work.
If I put the urls back into the main urls.py file get_absolute_urls  
works again.

I must be missing something very basic, but I'm pretty much stuck.

Thoughts ?

Grant

[ANN] django-nav 0.1

[Dj Gilcrease]

Examples and code can be found at http://code.google.com/p/django-nav/


Goals:
Create a extensible, non intrusive, fast system for generation
navigation groupings.


Reason:
While there are several systems already out there for crating
navigation menus, tabs, etc, they all (That I have found) fail at one
or more of my goals.

I want to create a system that any django app can use so that it's
default navigation appears or disappears in an existing site based
only on having the application in INSTALLED_APPS or not.


Implementation:
To meet the goal of non intrusive, and auto adding/removing the
navigation groupings I looked to djangos own admin autodiscover
feature and implemented a similar system that looks though all of your
sites INSTALLED_APPS to see if they have a nav.py file, if they do it
processes it.

... Further implementation details on the site



Over the weekend I plan on adding example nav.py files for many common
applications to help new users and future developers get a jump start
on their own sites and apps

You need ugettext_lazy instead of ugettext when declaring forms:
from django.utils.translation import ugettext_lazy as _

Read about it here:

Re: How do you unit test forms

[Rodrigue]

Hi Joshua,

whenever I override some of the Form methods, I make sure I have tests
that cover the code I wrote. In particular, when I override the save()
method on a ModelForm, I make sure that
  - the Model save() gets called from the Form save() if the form is
valid
  - my Form save() returns the object (a classic oversight for me).

I also try to make sure required fields are indeed required, and that
validation does validate/fail as expected.

I also like having good unit tests for my forms because then my view
unit tests can stop at the form level. What I mean is that if a view
uses a form, I can just test that
the correct type of form is instantiated and passed into the template
context, and that if I feed valid data to the view, the form save() is
called. This checks that the view makes correct use of the form, and I
trust the form to behave, because it has its own tests.

Cached forms when changing language- Is this a bug?

[Adrián Ribao]

Hello everybody,

I have an multi language site with a form in the home. If I change the
language of the site everything changes but the form takes a few
minutes before I see it in the right language.

If I reload the server the form is visualized ok, but this is not the
right behaviour.

The code of the form is somethin like:
from django.utils.translation import ugettext as _
class RuedaForm(forms.Form):
puntuacion_hogar = forms.ChoiceField(label=_(u'Value'), choices=
[('', '')] + [(i, i) for i in range(11)], help_text=_(u'help text'),
required=False)

I've noticed that if you change a form in the fly, the changes don't
appear in the site inmediatly, For example when I hidde form fields
depending of the permissions of the users.

We are really worried with the behaviour of the forms when changing
the language, something is wrong with it.

You can have a look at: http://autocoaching.info/

We really need help with this issue.

Thank you very much,

Adrian

Thanks. I'm guess I need to take a closer look at the forms
functionality. I don't think I'm using it properly. This is my first
Django project and I guess I don't always know enough of what I'm
asking about to ask a full question.

Thanks for the input.

Getting a dynamic model form

[~Young Devil]

I've a generic model to save the user preference with a key and value
However the view would change depending upon the key.

Example,
key : newsletter
view : radio button, yes and no

key : template type
value: drop down box [blue, white, brown]


Is anything like this possible in Django, I am kinda new to this
framework I did google it but couldn't get a good solution.

Thanks in Advance.

building directory path with user table

[neri...@gmail.com]

Hello,

I'm trying to build a photo upload path which corresponds to the
selected user i.e., when the user is selected from the drop down the
username gets appended to the file upload path dynamically. If you
have any ideas I would like to hear them:

class Listing(models.Model):
user = models.ForeignKey(User, unique=True)
user_directory_path = os.path.join(settings.MEDIA_ROOT, 'listings',
user)
user_directory = models.FilePathField(path=user_directory_path,
recursive=True)
photo = models.ImageField(upload_to=user_directory)
name = models.CharField(max_length=50)
order = models.ForeignKey('Order')

def __unicode__(self):
return self.name

I keep getting this error:

AttributeError: 'ForeignKey' object has no attribute 'startswith'
