Models inside tests - Django 1.7 problem

[galgal]

Hi,
I'm trying to port my project to use Django 1.7. Everything is fine except 
1 thing. Models inside tests folders.
Django 1.7 new migrations run *migrate*  command internally. Before *syncdb 
*was ran. That means if a model is not included in migrations - it won't be 
populated to DB (and also to test DB). That's exactly what I'm experiencing 
right now.

What I do is:

   - In my /app/tests/models.py I have dummy model: class TestBaseImage(
   BaseImage): pass
   - All it does is to inherit from an *abstract **BaseImage* model.
   - Then in tests I create instances of that dummy model to test it.
   
The problem is that it doesn't work any more. It's not included in 
migrations (that's obvious as I don't want to keep my test code in 
production DB). Running my tests causes DB error saying that *table does 
not exist*. That makes sense as it's not included in migrations.

Is there any way to make it work with new migrations system? I can't find a 
way to "fix" that.

Mock Django FileSystemStorage location?

[galgal]

I try to mock FileUpload in django view (admin view).

My model looks like that:

class BaseImage(models.Model):
# create path for uploaded images
_storage_path = os.path.abspath(os.path.join(
os.path.dirname(__file__),
'secure_media'))
_image_storage = FileSystemStorage(location=_storage_path)

image = SorlImageField(
verbose_name=_(u'image'),
storage=_image_storage,
upload_to="%Y/%m")

class Meta:
abstract = True

and test:

def test_add_new_as_main(self):
url = reverse('admin:galleries_secureimage_add')

post_data = {
'image': get_temporary_image()
}
response = self.client.post(url, post_data)

This uploads file to directory specified in _storage_path and I want to 
change that in my test.

How can I mock _storage_path to return different path in my tests? I tried 
to use Mock() library but can't make that work.

Can you help me?

Re: How to divide my apps? Good practices?

[galgal]

I've made a quick schema of couple of main tables. As you can see, there 
are many relations, so I think putting it all in one app. There will be a 
couple of additional models. There will be 1 more thing: a play systems. 
Some seasons can have simple table games but others - of example 2 rounds 
of regular matches etc... That will be a special, separated class for that, 
in the same app as rest I think.

What do you think?

Re: How to divide my apps? Good practices?

[galgal]

But I can see now that there will be a massive amount of models. Each player 
should have his own statistics for each games, there will also be a part for 
referees. Referee work will be rated by users so - many models is planned. If I 
put it in one app, I will have at least 15 models in it and I think it will 
increase in some time

Division in my example will clarify it, for example players app with all models 
for players like player base, player in season, player statistics and of course 
all logic in it.

In 1 app there will be a many many lines of code and after some time it will be 
hard to develop I think.

Re: How to divide my apps? Good practices?

[galgal]

@Mayukh Mukherjee yes, I have that in mind. That's why I'm asking about 
it:) I'm confused now and need any advice if that all models should be in 1 
app, or in couple of apps.

I'm rather convinced to make couple of apps

   - teams (models with teams - at least 2 models. team as global in my 
   app, and team in the season (its name, etc))
   - players (the same as above)
   - leagues with different competitions systems
   - etc...

It should be better in future to develop new features.

How to divide my apps? Good practices?

[galgal]

Hi,
I'm starting my new project. It's sport-connected.
The main part of my app will be league, matches, teams and players. There 
will be many relations.

So, how to make apps and models. I plan to make models:

   - Season
   - League (FK to Season)
   - Team
   - Match (FK to League and 2FK to Teams)
   - Players (FK to Team)
   - and many more to present teams history in each season etc.
   
Is it better, to make it all in 1 app, called for example Game, or divide 
it into smaller apps?
Thanks for help.

Get all objects that don't belong to M2M

[galgal]

I have a model with field:

class Product(models.Model):
subproducts = models.ManyToManyField("self", blank=True)

I need to overwrite admin's field queryset, to display only that objects 
that don't belong to any m2m relation. I have no idea how to get them.

So if I have: product1, product2, product3, product4.

product1 contains in subproducts: product2

I need a query that will get, in that situation, product3 and product4

Any idea how to get that?

dynamic form fields in admin?

[galgal]

I want to make some advanced customization of admin form.

While editing an object, I want to show, dynamically, different fields 
depending of 1 obj field (they are not visible while adding the obj.). 
There can be a situation, to validate that extra fields. For example, when 
object has a 'temporary' type, I must show 2 fields with dates, and 
validate them. If object is 'renewable' I need to show 2 different fields 
with different validation.

What is the best approach to do that?

   - Make separate Form for each object type and set form attrib of 
   ModelAdmin? If yes, in whichModelAdmin method do that (change_view()?)?
   - Dynamically update 
fields
in get_form() method?

What is the best approach to do that?

Relations to unknown models?

[galgal]

Hi.
I'm looking for a solution to make site-wide comments that can be connected 
with different models via FK.
I want to make 1 global model Comments. I want to make a relation to 
Articles, Relations and Solutions models. I the future I plan to add 
additional models. Now, Comments model should allow me to make relations to 
any of that models via FK. What is important, I need to have 1 and only 1 
Comments model, and it won't be abstract model.
On site I want to display stats showing how many comments were added to 
each model.

Any suggestions?

sorl-thumbnail or easy-thumbnail

[galgal]

What image engine to choose sorl-thumbnail or easy-thumbnail? I saw on 
github, that easy-thumbanil is still updates, and sorl last update is about 
5 months ago.
I use sorl for a while but want to try something else. Does easy-thumbnail 
work in admin when image are displayed? sorl has a special admin class - i

admin - user related modules in admin

I use extended user profile (class name: UserProfile). I made an app for 
this, named account. In settings I have set:AUTH_PROFILE_MODULE =

But I made another model in that app named RestrictedUsername. I want to 
put there usernames, that will be reserved and not available in register 
process. I don't know why, but it doesn't appear in admin panel. I 
registered it:
>
> from django.contrib import admin
> from apps.account.models import RestrictedUsername
> class RestrictedUsernameAdmin(admin.ModelAdmin):
> list_display = ('username',)
> search_fields = ('username',)
> admin.site.register(RestrictedUsername, RestrictedUsernameAdmin)

cache problem but query is OK

[galgal]

I try to make a very simple cache usage:
myquery = 
UserProfile.objects.select_related('user').filter(status__exact=1).values_list('user__username',
 
'q_points').order_by('-q_points')[:50]
cache.set('test_cache', myquery, 3600)
print cache.get('test_cache')
I get an error:
UserProfile has no field named 'username'
The thing is query is OK and returns valid results.

Debug Toolbar shows that cache value:
([(u'admin', 2L), (user1', 0L), (testuser', 0L)], 3600)

I have no idea what is wrong :/

CSRF with AJAX problem

[galgal]

I have a problem/bug found? in AJAX with CSRF. I don't use {% csrf_token %}

case - https://docs.djangoproject.com/en/1.3/ref/contrib/csrf/#ajax is 
useless :(
I can use get_token to generate it, but I have to put it in all my sites so 
it has no sense.

Admin - delete with removing FK objects

[galgal]

I have 2 models

class Article(models.Model):

title = models.CharField(max_length=150)

class ArticleGallery(models.Model):

article = models.ForeignKey(Article)

image = 
models.ImageField(upload_to=settings.ARTICLE_GALLERY_IMG_UPLOAD_TO)



def delete(self, *args, **kwargs):

self.image.delete()

super(ArticleGallery, self).delete(*args, **kwargs)


But when i click delete in Article and submit it, elements are removed from 
database but ArticleGallery.delete() isn't fired up.
I need the delete method to be run when deleting Article. Any clues?

JavaScript translation problem

[galgal]

Hi I have a problem with JS translation in Django. I did everything like is 
said in documentation, so: I made .po then .mo files (django.mo, 
djangojs.mo). Translated files are in path: *myapp/locale/pl/LC_MESSAGES/* 
and *myapp/locale/en/LC_MESSAGES/* *Translations in .html and .py files work 
OK.* The only problem is that JS translation always displays original 
phrase, not translated. main urls.py:

urlpatterns += patterns('', (r'^jsi18n/$', 
'django.views.i18n.javascript_catalog',{}), )

template file in header (as first JS part):



All my js files are in path /myapp/site_media/js/ and the only .mo files are 
in path which I wrote before. I use gettext() in JS strings.

What did I do wrong?

admin - delete_selected problem

[galgal]

In admin.py file i paste:admin.site.disable_action('delete_selected')



And get an error:


KeyError at /

'delete_selected'

Django Version: 1.3 Exception Type: KeyError Exception Value:

'delete_selected'

Exception Location: 
c:\Python27\lib\site-packages\django-1.3-py2.7.egg\django\contrib\admin\sites.py
 
in disable_action, line 127

Any idea why it occurs? In my previous websites I haven't that error and it 
is strange for me.

Admin - change ForeignKey display text

[galgal]

How can I change the display text in select while selecting a field which is 
as ForeignKey? I need to display not only the name of FK, but also name of 
it's parent.

Anybody can give a clue?

Method call when deleting FK in admin

[galgal]

My models:class Spectacle(models.Model):

title = models.CharField(max_length=100)
slug = models.SlugField(max_length=100 unique=False)
description = models.TextField()
class SpectacleGallery(models.Model):
spectacle = models.ForeignKey(Spectacle)
image = models.ImageField(upload_to=upload_path_handler, max_length=255, 
help_text=_(u'tylko pliki z rozszerzeniem .jpg'))
image_thumb = models.CharField(max_length=255, editable=False, blank=True, 
null=True)
def delete(self, *args, **kwargs):

image_thumb_abs = settings.MEDIA_ROOT + str(self.image_thumb)

# try to delete thumb and image

try:

remove(image_thumb_abs)

except Exception:

pass

try:

self.image.delete()

except Exception:

pass

super(SpectacleGallery, self).delete(*args, **kwargs) # Call the "real" 
delete() method.

#try to delete dir

try:

removedirs(settings.SPECTACLE_GALLERY_UPLOAD_PATH + str(self.spectacle_id))

except:

pass


Now in admin, when I delete from SpectacleGallery file is being deleted from 
disk and DB properly. The problem is when I want to delete Spectacle. 
Deletion page is asking if i'm sure to delete Spectacle and all related 
images. I confirm and: all records from database are deleted. Unfortunately 
files from SpectacleGallery are not deleted.I paste print into delete() 
method in SpectacleGallery. Nothing shows so my question is: Why delete 
method is not called when deleting it in that way?

How to disable specific field validaton in form?

[galgal]

I need to disable field validation in ModelForm. I want this validation not 
to validate some field. I have some situations (AJAX rendering form) when I 
want to return more complex form with additional fields. I pass POST to the 
form and render new one with post fields saved. Some new fields are added 
and they can't be validated. I pass flag to form and recognize when it 
happens. Should I make it in some clean functions?

Why? File is a proper image. Does that file in save methos is not a good

How to use 2 different cache backends

'LOCATION': 'c:/foo/bar',
},
'inmem': {
'BACKEND': 'django.core.cache.backends.dummy.DummyCache',

}
dummy is temporary.
Docs says:
cache.set('my_key', 'hello, world!', 30)
cache.get('my_key')
OK, but how can I now set and get cache only for 'inmem' cache backend (in 
future memcached)? Documentation doesn't mention how to do that.

Djando admin - custom error when deleting

I would like to use validating fields connections, but ONLY when delete

via admin, chech them and if something is wrong - display errors in admin. I 
use custom ModelForm as admin form, but have no idea how to check in it's

how to change form field in admin?

[galgal]

Is there any way to change type of 1 specific field? I want to change 1 
field from CharField to TextField. I know I can make a modelform and pass it 
to admin class, but is there any other way?
For example - can I somehow use formfield_for_dbfield?

Re: AW: MEDIA_URL not treated like static

[galgal]

I forgot to tell I'm using Django 1.3. In that case - how to make it work 
with separate dirs? Or it can't be done on dev server?

MEDIA_URL not treated like static

[galgal]

I have that dirs structure:
site_media/
|
---> static/
|
---> uploads/

static dir is set as STATIC_URL = '/site_media/static/'
uploads dir is set as MEDIA_URL = '/site_media/uploads/'

In that case on dev server (localhost:8000) media_url is not accessible via 
browser as static file, and whe I try to access it I get 404 error. How can 
i set it up to be seen as static?
In uploads dir are all files uploaded by users. static dir includes all my 
js/css/images

url - hot to set properly?

[galgal]

I need to make some settings in urls. I want admin site enabled and 1 view 
method to catch rest of the request parts.
So if someone's url is :/admin - ADMIN panel is show, also if someone pass: 
/admin/ (/ <- is important)
If someone pass: /, /contact, gallery,. my custom method is activated.
The problem i have is / on the end.

My urls:

from django.conf.urls.defaults import patterns, include, url
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
(r'^', include('apps.textcontent.urls')),
)


My app url:

from django.conf.urls.defaults import *
urlpatterns = patterns('apps.textcontent.views',
url(r'^(?P.*)$', 'index', name='index'),
) 


when i pass: /admin/ all is ok, but when I pass /admin - 
 apps.textcontent.urls are executed, but why?
