Django pass an url to template for reusable code
My question is if it's possible to pass a named url from the view to the template for reusing template code, something like this, but it's passed as raw string. class PersonCreateView(CreateView): ... def get_context_data(self, **kwargs): context = super(PersonCreateView, self).get_context_data(**kwargs) context['myurl'] = "{% url 'people:person-index' %}" return context And in the template: <a class="btn btn-default pull-right" href="{{ myurl }}" role="button"> Thanks! -

using __import__ on a module in a different directory python. django
I am attempting to import a model from another app in django. The following attempts fail fails: from venueadmin.models import VenuePermissions fails how: Python is not able to located VenuePermissions, i guess circular reference? from django.apps import apps suitscity = apps.get_model('suitsandtablesadmin', 'City') fails how: raise AppRegistryNotReady("Models aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet. so then I tried importing using __import__ suitscity = __import__('suitsandtablesadmin.models') suitscity = getattr(suitscity, 'City') and suitscity = __import__('suitsandtablesadmin/models') suitscity = getattr(suitscity, 'City') all of which did not work because City is in a different directory suitsandtablesadmin how can I make any one of these work -

The request's session was deleted before the request completed. The user may have logged out in a concurrent request, for example
I have a Python/Django app which sometimes has more than 100 users logged in. One day, I found this in Django error log: The request's session was deleted before the request completed. The user may have logged out in a concurrent request, for example. Although the message is written in quite understandable English, I have no idea what actually happened why it happened whether I need to worry about it if yes, how can I prevent this from happening again I found a question with almost same title but the difference is that I do not have anything about caching in my settings. If you need any pieces of code, just please let me know in the comments. Thanks for your time! -
Django - remove duplicates records from DB
I want to set 'unique_together' on my DB (postgres). The problem is that I may already have duplicates on DB, so migration would probably not work. So as I see it - before the deployment I need to run some script to remove all duplications (leave only one of each). I prefer doing it with Django Custom Command. The table 'mapping' looks something like - Id, user_id, user_role, project_id, user_type. I want to set 'unique_together' for all of them. And the script I use to retrieve duplicated rows is- duplicates = (Mapping.objects.values('project_id', 'user_id', 'user_type', 'user_role').annotate( count=Count('id')).values('project_id', 'user_id', 'user_type', 'user_role').order_by(). filter(count__gt=1)) It returns list of objects that contains the duplicated attributes. for example: QuerySet [{'user_id': '2222', 'user_type': '1', 'user_role': '1', 'project_id': UUID('c02bda0e-5488-4519-8f34-96b7f3d36fd6')}, {'user_id': '44444', 'user_type': '1', 'user_role': '1', 'project_id': UUID('8c088f57-ad0c-411b-bc2f-398972872324')}]> Is there a way to retrieve the Ids directly? Is there a better way? -
django - allauth and rest-auth facebook login token does not work with JWT authentication
I've followed the both packages documentations and using example from rest-auth doc. I've followed all the steps and I can successfully use this API to register/login user with facebook. API returns me token and user object but this token is not working with JWT authentication. But if I set this user's username in the db and then post the facebook login request again then returned token works fine. What does this social authentication process has to do with username? Is there something I need to do to properly configure it? I am using custom user model and have both username and email for authenticating users. Please let me know if any further info is needed for figuring out the problem. -

dynamically importing models in django throws models not ready
in my venues app model file I am dynamically adding models I need to do work. from django.apps import apps state = apps.get_model('suitsandtablesadmin', 'State') suitscity = apps.get_model('suitsandtablesadmin','City') suitsneighboorhood = apps.get_model('suitsandtablesadmin', 'Neighborhood') venuetypes = apps.get_model('suitsandtablesadmin', 'VenueTypes') venueseatingtypes = apps.get_model('venueadmin', 'SeatingTypes') costofvenue = apps.get_model('venueadmin', 'VenueCost') venuecusines = apps.get_model('venueadmin', 'Cusines') roomprivacy = apps.get_model('venueadmin', 'Roomprivacy') roomamenities = apps.get_model('suitsandtablesadmin', 'Amenities') I am doing this because a regular import statement will not work. Python says it can find the model, I am guessing because of circular importing. I see from this stackoverflow answer that it may be best to import the entire app into the file but how will that help?

Django OneToOneField on foreign table
I'm trying to setup a new server with foreign tables (using postgres_fdw) that weren't foreign tables previously, and I have some OneToOneFields pointing to these tables. This doesn't work out of the box - OneToOneFields use foreign keys, and postgres_fdw does not support foreign keys for foreign tables. The foreign tables are in a read-only database on the same server. Is there an easy way to get this working? -
