In my Django application I have Guest user accounts that are created for all

  • 0

In my Django application I have Guest user accounts that are created for all unregistered users (they all have email=’guest@mysite.com’). At the same time I create some demo objects related to the Guest account.
These objects live in the same table (have the same model) as objects for registered users. And I have more that one type (model) of these objects like:

class Object1(models.Model):
    user = ForeignKey(...)
    ...

class Object2(models.Model):
    user = ForeignKey(...)
    ...

And what I would like to achieve is to filter out all objects related to guest accounts when I view them in django admin.

Right now I subclass django.contrib.admin.views.main.ChangeList and override get_query_set method to do the required exclude, and I redefine get_changelist method of django’s ModelAdmin class at runtime:

class FilteredChangeList(ChangeList):
    def get_query_set(self):
        qs = super(FilteredChangeList, self).get_query_set()
        if is_related_to(self.model, Profile):
            qs = qs.exclude(user__email='guest@mysite.com')
        return qs

def my_getchangelist(self, request, **kwargs):
    return FilteredChangeList

ModelAdmin.get_changelist = my_getchangelist

I suppose redefining django’s methods at runtime is a bad practice, so is there any correct solution for the problem?

    Guess you are doing a lot more work than necessary. You could also create your own ModelAdmin class and overwrite its queryset method, no need to construct your own ChangeList class:

    class MyFilteredAdmin(admin.ModelAdmin):
    def queryset(self, request):
        qs = super(MyFilteredAdmin, self).queryset(request)
        if is_related_to(self.model, Profile):
            qs = qs.exclude(user__email='guest@mysite.com')
        return qs

    You could then either register your models directly with this new admin class – admin.site.register(Model, MyFilteredAdmin) – or create subclasses that inherit from MyFilteredAdmin instead from django’s ModelAdmin.
