Django's databrowse is very different from the rest of django in that the docs literally don't exist. Has anyone tried to do more that databrowse.site.register on a model? Any code examples?
In particular, I've got a model that has a ForeignKey to an auth.Group and I want databrowse to use this queryset instead of .all():
qs = Model.objects.filter(group__in=request.user.groups.all())
Bonus points for making it possible to have a button that does stuff with the current object (edit/delete/clone/etc). I basically need a simple way to browse and edit rows without giving users access to the admin.
It'd be even better if there was a way to do that on the admin, but I don't want to give users the staff privilege.
There's no way to do this through databrowse. You could try writing a custom Manager for your Model and return the required query set by default.

I am new to Django.
I am going to build simple register and login fullstack application by using React and Django.
My problem is when I received register request with form data.
Is it ok to create custom table for users?
I am going to create another table related to user table.
So in that case, there must be id in the users.
That's why I am going to create custom table.
Please help me it is good practice.
You can abstract from AbstractBaseUser and then you can customise the user model and to specify it in your settings file.
Please see the django documentation here:
https://docs.djangoproject.com/en/4.1/topics/auth/customizing/#substituting-a-custom-user-model
In Django you can link between multiple table by different relationships depends on what you want like:
OneToOne
ForeignKey
ManyToMany
And by default when you create a model django create a pk field it is ID for table, you can make another field as a primary key for model
When you use one of those relationships django by default use model id to link between them
and you can also create a custom user model to use it
Good luck
is there any way to create views like the ones shown on Admin Panel without any effort, I mean, generic views that display all the fields and have the ability to add foreign key items and such, just like admin panel?
I've tried using
django.views.generic.edit.FormView
django.views.generic.edit.CreateView
django.views.generic.edit.UpdateView
django.views.generic.edit.DeleteView
But I am forced to specify fields, and I have quite a lot. It also doesn't allow me to create objects for the foreignkey fields if there's any.
Thanks in advance.
I have created an application that uses django-rest-framework. The problem is that in production with lots of data, the rendering of HTML pages will timeout. This is caused, I believe, by the select fields that represent ForeignKey of the model that take too long to render when all the production data is available. What is the most approriate way to prevent this?
As far as I understand, the problem is with the selectbox loaded with tons of items. The solution that is being used in django admins is to use "raw_id_fields" for the choicefields (or foreign keys) that have lots of items.
Unfortunately, DRF doesn't support Raw ID fields for now. However, you can implement a similar approach by using autocomplete fields. Right now there isn't built-in support, but you can use some external packages as described in DRF's official documentation: http://www.django-rest-framework.org/topics/browsable-api/#autocomplete
You should use select_related()/prefetch_related queryset methods to fetch the associated objects, which fill your selects. Post your models, serializer and a queryset so we can make a real example.
I am using django admin site to let people manage database easier.
For some reason, I want to hide some data from some user.
Let's say I have a model named Book and there are a lot of books in database. I want different user has the different scope of books he can view.
How would I do that?
I am thinking about permission. Is that possible to set the permission to filter the data?
I know how to create permission according to a specified model. However, after that, how do I suppose to use that permission? I believe I may need to override part of "changelist_view" method under BookAdmin class, right?
Any help would works.
Thanks in advance
Use the queryset method on your admin model. Something like:
class BookAdmin(admin.ModelAdmin):
def queryset(self, request):
return super(BookAdmin, self).queryset(request).filter(owner=request.user)
Obviously the filter will vary depending on your book model, but this is the general idea.
I am trying to make an overview page for one of my models I have read through all of http://www.djangobook.com/en/1.0/.chapter17/ and understand how I can add my own custom views for a model to the django admin.
What I am currently trying to do is add multiple filtered change lists (presenting some child models) onto my "overview" page for the model. In these I would like to be able to make use of some of the admin features such as editable fields or actions.
Does anyone have some pointers on how I can best get started with this.

He created a proxy model for the original model to avoid the conflict. You can create a new model admin or inherit the old ModelAdmin(as shown in the link)
