Compiled Sass files not found by Django-pipeline
I'm having trouble with running django-pipeline because I keep receiving errors similar to: ValueError: The file 'css/main.b7ade0b8392c.css' could not be found with <pipeline.storage.PipelineCachedStorage object at 0x7f66c22ef550>. When I perform an ls operation in my css folder, the css file that is present is called main.c2b6ea9fa0e1.css, which is different from the file that django-pipline is looking for. My django-pipeline configuration looks like this: PIPELINE = { 'PIPELINE_ENABLED': True, 'STYLESHEETS': { 'main': { 'source_filenames': ( 'css/main.scss', ), 'output_filename': 'css/main.css' }, 'COMPILERS': ( 'pipeline.compilers.sass.SASSCompiler', ), 'CSS_COMPRESSOR': 'pipeline.compressors.NoopCompressor', 'JS_COMPRESSOR': 'pipeline.compressors.NoopCompressor' } This problem only seems to be happening when I have DEBUG=False. I try to perform python manage.py collectserver before restarting the Apache server, but to no avail. I'm using Apache, Django 1.9.9, Python 2.7. -

Django: Storing Images Database

Django admin search for multi-word phrase with ^ and = operators
Assume a model admin has: search_fields = ("^name", "=kind") If name is "Leonardo Da Vinci", it can be found using the query Leon or Leonardo, but not Leonardo Da or Leonardo Da Vinci. If kind is e.g. "polymath genius", such a value cannot be found with any query. Ideally, one would be able to post "multiple words" "Leonardo Da" and get this record; but given how Django splits the query, it doesn't do what one might expect. This problem was apparently raised 9 years ago in this ticket, and solved. Then Django got rewritten and apparently this got dropped somewhere. Does anyone have an idea if this is possible? I'm probably thinking I'd need to override ModelAdmin.get_search_results... Anything more elegant? -
Need help in understand Django-Facebook API and the Post extraction form a profile suing Python2
I am working on my machine learning project where I am in a great need to access the textual posts of the people from Facebook, of course with permission, and then process it to find the best personality traits. I am struggling to find a way to merge my application with something that can give me the post of the people from their profiles. Hence, I found something in the documentation of the Django-Facebook API. Here is the link for the documentation: http://django-facebook.readthedocs.io/en/latest/installation.html Here what I am not able to understand is how I can use this for extracting the post of the people? Can anyone give a small example that can be helpful in understanding what I can do to extract the text from the people profile and use it in my application. -
GAE: ImportError while using google-auth
I am using google-auth to allow firebase authentication in my GAE project. Everything works fine when I run the code locally using dev_appserver.py or when I deploy it to google app engine. But I get this ImportError exceptions when I try to use Django's manage.py script to create/run migrations. ```ImportError: Could not import 'firebase.authentication.FirebaseAuthentication' for API setting 'DEFAULT_AUTHENTICATION_CLASSES'. ImportError: No module named auth.transport.requests. The google-auth module is installed under lib directory and has this structure: - lib - google - auth - oauth2 These import cause the ImportErrors: import google.auth.transport.requests from google.oauth2 import id_token My guess is that there might be naming conflicts as other imports work fine. Please help! -

Django template tags filter by slug
I have a many-to-one relationship between organizations and events. One organization can have many events. I have a template for showing all events that everybody can see filtered by city. But I want the organization detail view to show events belonging only to a specific organization. models.py class Organization(models.Model): name = models.Charfield(max_length=27) slug = models.SlugField(max_length=25, null=True, blank=True) [...] def __unicode__(self): return self.name class Events(models.Model): org = models.ForeignKey(Organization, on_delete=models.CASCADE, default=1) time = models.DateTimeField(null=True, blank=True) city = models.CharField( max_length=25, choices = CITY_CHOICES, default = 'NY' ) [...] def __unicode__(self): return '%s %s' % (self.org, self.time) I use this template tag to filter events by city (NY for this one): @register.inclusion_tag('mysite/event_list.html') def event_ny_tag(event): return {'events': Events.objects.filter(linn='NY')} url.py urlpatterns = [ url(r'^$', HomePageView.as_view(), name='home'), url(r'^organizations/$', OrganizationList.as_view(), name='organizations'), url(r'^events/$', EventList.as_view(), name='events'), url(r'^(?P<slug>[-\w]+)/$', OrgDetailView.as_view(), name='org_detail'), ] But how can I filter events only by one specific organization? There are only two cities but 20 organizations. How to do it without hardcoding it? With a slug? This is not a copy paste. Just a sample code similar to mine. -

Multiple versions of web API. Separate models for each version?

Django Security issue
So I have just completed my site, it is a basic social network. Each user has a profile and can edit their profile.

How do I stop that?? -

How to setup a DJANGO REST that requires information from a POST request?
I am trying to construct a class based Django REST API that takes in data from the POST request and outputs the relevent data. I have a list of buildings in the DB State Building California Golden Gate Bridge New York Empire State California TransAmerica New York Brooklyn Bridge The POST request will specify the state, and the API should output the appropriate building. I guess I'm just having a hard time understand how the class is taking in the request.data ['state_id']. Should I use APIView? So many questions! So far I have this in my view.py class BuildingViewSet(viewsets.ModelViewSet): queryset = BuildingRule.objects.values('building_name').distinct() serializer_class = BuildingSerializer def post(self, request, *args, **kwargs): queryset = BuildingRule.objects.filter(state_name=request.data['state_id']) return Response(queryset.values_list('building_name', flat=True)) This is in my serializer.py class BuildingSerializer(serializers.ModelSerializer): class Meta: model = BuildingRule fields = ('building_name',) This is my url.py: router.register(r'buildings', views.BuildingsViewSet, base_name='Building') -
Accessing user object when creating a user in Django
I'm using Django 1.10.6 and I'm working on a user registration form. During the validation process in my forms.py I'm trying to call the UserAttributeSimilarityValidator from within the clean method, but I'm having some trouble figuring out what the user object argument is that it requires.

How to keep form data when post fails and redirect with an error messages in Django?
I have been trying to look around but most answers are outdated. I have simple form and I am using python/django in my backend. index.html <form action="/add_blog" method="post"> <label for="title">Title</label> <input type="text" name="title" value=""> <label for="blog">Blog</label> <input type="text" name="blog" value=""> </form> There are more field there that when the form gets submitted and fails my backend validation, it will redirect back to 'index.html' and display some error messages. The question is, how can I preserve inputs so that when the post fails validation, the user won't lose their inputs and gives them time to edit their mistake. I have tried doing this: <form action="/add_blog" method="post"> <label for="title">Title</label> <input type="text" name="title" value="{{title}}"> <label for="blog">Blog</label> <input type="text" name="blog" value="{{blog}}"> </form> but it I need to pass a context on a redirect somehow. Is there a better and clean way to do this? Thanks a lot! -
