Django - create instance of model with user_id
I have two models, player and game. The model player is an extended Django Auth User Model. I am trying to create an instance of game with the User ID and not the player ID which is automatically created. Is it possible to do that in a single query? Django Version: 1.11. new_game = Game(active=False, ### user_id=request.user.id, display_every=display_every, lead_to_win=lead_to_win, p1_coins=num_of_coins, p2_coins=num_of_coins, created=django.utils.timezone.now()) new_game.save() This command creates the instance. Its the user_id which is not working and it only works with player_id which I have to fetch with another query.

@shared_task decorator doesn't work
The problem: @shared_task decorator doesn't work, when I import data from custom files. I mean, when I start celery, all tasks under @shared_task doesn't appear in list of tasks.

Design of web application
I'm building a web application(django) that provides interface to call some data analytic APIs. The APIs are developed together as part of the web application. However, I plan to use Ajax to invoke these web services(expensive task) since i do not want the UI to be blocked. Currently while i was researching i came across this tool celery and I'm not sure how it fits into the picture or if I'll even need it since I'll be invoking the web services via Ajax. -

(django) create static variable stored in database and accessible through admin
I have a blog that should publish articles in a weekly rythm. I ordered these articles with a number attribute which is a PositiveIntegerField that's not editable through admin. (And it's 1-based) Now I want to get the pub_date. (Which is simply the day the article becomes published. It should be a value in the normal date-formate.) There is always the day, I start the blog (I don't want to hard-code this because I'm still in beta, and it didn't worked when I tried it) and every week one article should be published. Let's call the day I start the ZERODAY. pub_date is now ZERODAY + timedelta(days=7*(self.number-1)). (Remember, self.number is 1-based.) Because I can do that simple math I don't want pub_date becoming a database field. (It would mean trouble because at least the two are the same information and it would mean to have more db fields than needed.) So I think I should create a static variable ZERODAY (a models.DateField) that I can acces and change through admin. -

Django Foreign Key err 150
I have an article app article/models.py looks like: class Person(models.Model): PersonID = models.BigAutoField(primary_key = True) # Some other fields. class Blog(models.Model): BlogID = models.BigAutoField(primary_key = True) person_blog = models.ForeignKey(Person) When I migrate it using: python manage.py makemigrations article python manage.py migrate I am using Django 1.10 and MariaDB. I ran python manage.py sqlmigrate article 0002 to check out the SQL commands being executed. I found that the error was due to mismatch in datatypes of person_blog field and PersonID field. PersonID is BigInt whereas person_blog is Int(11). The problem is that Foreign key field conversion to SQL code is a 3 step process: Create a field Create an INDEX Alter Table and add constraint for foreign key. There is no way in django migration to create an normal INDEX. How can I create foreign key manually using django migrations. -
How to pass a view function with arguments in a decorator to another decorator in django
I have been trying to find a solution for this for hours. I have already gone through many SO posts like this, this and this. I am using django-guardian to implement object level permissions in my django app. I am trying to implement permission_required decorator dynamically. The idea is to create another decorator which can switch between permission required decorators and then pass view function to respective permission_required decorator. urls.py urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^$', Test.as_view()), url(r'(?P<handle>[-\w]+)/(?P<method>[-\w]+)/(?P<id>[-\w]+)/$', Test.as_view(), name='handler'), ] Views.py class Test(View): @decorator_switch def get(self, request, *args, **kwargs): return HttpResponse('Test View') decorator_switch from api.mappings.permission_mappings import perm_mappings def decorator_switch(func): def wrapper(instance, request, *args, **kwargs): print(kwargs) permission_decorator = \ perm_mappings.get('handles').get(kwargs.get('handle')).get('actions').get(kwargs.get('method')) return permission_decorator(func)(request)(args)(kwargs) return wrapper permission_mappings from django.contrib.auth.decorators import permission_required as django_perm_req from api.decorators.guardian_perm_req import permission_required as guardian_perm_req from pyteam.models import Team perm_mappings = { 'handles': { 'team': { 'actions': { 'get': guardian_perm_req('pyteam.retrieve_team', (Team, 'id', 'id')), 'create': django_perm_req('pyteams.add_team', raise_exception=True), 'update': guardian_perm_req('pyteam.change_team', (Team, 'id', 'id')), 'delete': guardian_perm_req('pyteam.delete_team', (Team, 'id', 'id')) } } } } After this I opened url http://localhost:8000/team/get/1/ But I got an exception GuardianError at /team/get/1/ Argument id was not passed into view function I checked in kwargs of views as well as kwargs of decorator of decorator switch for … -
PHP vs Python for web application development [on hold]
I am starting out to build an application for university students as my last semester project. A lot of online research tells me that Python has an edge over PHP in the long run, and I'm quite keen on choosing Python along with Django based on that feedback. I would really like some more insight from experienced programmers on this. P.S. I have worked on building a web application with JSP and some front end previously, and have some basic HTML, CSS, JavaScript, jQuery and Ajax knowledge. (None with Bootstrap, angularJS or Node.js). I have some basic Python knowledge as well, and absolutely none in PHP. I have about a month to finish this project, so as much as I want to learn from this, I also want to deliver it by the deadline. -
