问题 I am trying to do group my data on the basis of Year, Month and a Column Value.

I asked around in the #django room on freenode and the consensus was that this was probably due to the recent caching changes made in 1.3 Does anyone have any idea on how I can wipe out the cache entry for a model

问题 I'm working on a project using Python(3.7) and Django(2.2) in which I have implemented models for multiple types of users by extending the base User model. Now I need to implement a way to allow the admin user to edit a user ( can't use the default Django admin). So, I have utilized the MultiModelForm to combine multiple forms on a single template, on the get request the form is loading properly with data populated. Here's what I have done so far: From models.py : class User(AbstractBaseUser,

问题 In my API, I have two models Question and Option as shown below class Question(models.Model): body = models.TextField() class Options(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) option = models.CharField(max_length=100) is_correct = models.SmallIntegerField() While creating a question it would be nicer the options can be created at the same time.

问题 Hello and thank you in advance, I am very much a Django/Python noobie. I just need guidance, not necessarily answers. I have read all the pertinent documentation and I can't seem to find a concise example of what I am trying to do. I have two views, one is a form and the other is a view that lists data contained in a database table.

问题 I'm trying to show user group permissions in Django and show them in a "Drupal" style like a matrix. It works, but it takes too long to make the query and paint it in the template. Is there some way to improve my code? view img up(accomplished),down(views and template.html) views : def GroupPermissionsView(request): title = "Groups Permissions" groups = Group.objects.all() permissions = Permission.objects.all() context = Context({ 'title': title, 'groups': groups, 'permissions': permissions,
