How to dynamically set 'DJANGO_SETTINGS_MODULE' in celery.py , Based on different django settings
Anshu
Anshu
video_url = models.URLField(blank=True)
is_video = models.BooleanField(default=False)
is there any way to create depended model. means if video_url field is empty so is_video is store False or if there any value so the value is True
This method fires immediately after the model save event
That's when u can make the Boolean field as true
Harsh
what is that
In your model class
Override the default save model and call the superclass's save method at the end.
Lemme send you an example

Look at the Django CookieCutter project, it is an extremely well made boilerplate, you'll find how they manage that

Why not use class based view with permission mixins

CBVs allow you group related logic, it also help maintain the Django DRY principle. You can create an abstract CBV with permission mixins as your want, name each CBV a permission mixin similar to the group, then reuse it anywhere you want.

Check out ccbv.co.uk for structural details of CBV and how you can explore them to suite your need

You can also check out permission mixin on Django official docs.

For FBV, you may want to use permission based decorators but the code can clog up quickly when you start stacking decorators. So CBV may be a cleaner way to address your need.
I hope this helps.

I saw some examples with cbv and fbv but one could not able to get it in both the cases how to use it with 5 groups , the example are available only with 1 group
Ex for fbv
Def somegroup(user)
If user:
Return user.group.filter(name='student').count() == 0
What if user belongs with 2 groups at the same time or it refers to some other group ... It is confusing me up.
Nayan
The decorator we use here is
@user_passes_test(some group)

Paint a clear scenario of what you want to do. Sure someone where can proffer a solution. Right now you're being conveniently vague.
Nayan
Sure will do it .

@boiyelove sorry, mistake in spam protection, i'll look into it

@boiyelove sorry, mistake in spam protection, i'll look into it
Thanks. Sadly I lost all the info I typed in response to Nayan detailing how to help solve his problem.
Thanks again for the unban
Inuk
Sure will do it .
this is what @boiyelove said:
https://docs.djangoproject.com/en/3.2/topics/auth/default/#permissions-and-authorization
Use custom logic for texting user has the right perm
https://docs.djangoproject.com/en/3.2/topics/auth/default/#django.contrib.auth.mixins.UserPassesTestMixin
This is the permission required decorator for FBV;
https://docs.djangoproject.com/en/3.2/topics/auth/default/#the-permission-required-decorator
This is the mixin for CBV
https://docs.djangoproject.com/en/3.2/topics/auth/default/#the-permissionrequiredmixin-mixin
If you're worried your user belongs to multiple groups (although I'm unsure why this is a problem), you can
1. create group such that permission 1 belongs to group a but not group b
OR
2. Do your permission checks based on "permissions" directly and not based on groups.

Great. Glad you were about to recover it.
Nayan please read this for context.
Yes let me figure it out tomorrow if it did not work i will represent what i am trying to do .

You can create a permissions.py file to create custom permission classes based on the groups.
William
While implementing on views you need to import the permission classes and use it permission_classes list

Use prefetch_related on the group users field.

Can you please write the code
GroupChat.objects.prefetch_related(Prefetch('groupusers', queryset=User.objects.filter()))
