Example of ORM in Django to find out the data whose content is not empty

How to find out the data whose content is not null when manipulating database in django?

from  import Q
 
class Index(VIew):
 def get(self, request):
 userObj = (~Q(asset_id = '')
 return HttpResponse('yes')

The (~Q(nick = '')) in the above code uses the Q function to find out the data where nick is not null, mainly using ~Q

: (fields.E304) Reverse accessor for ‘' *es with reverse accessor for ‘'.

HINT: Add or change a related_name argument to the definition for ‘' or ‘'.

Reason:

Caused by referencing a foreign key table multiple times in a table and not specifying a unique RELEASED_NAME.

Solution:

Take the foreign key in the same table and add a different released_name.
