I am trying to get a particular object from Django... When I use filter it returns more than one and I need just one and I don't want to my fields unique... Is there a way I can get object by id since id will be the only unique field by default in Django Sqlite

CodePudding user response：

You can use two methods get() or more better get_object_or_404() as it calls get() on a given model manager, but it raises Http404 instead of the model’s DoesNotExist exception.

Implementation of get():

SomeModelName.objects.get(id=id)

Implementation of get_object_or_404():

from django.shortcuts import get_object_or_404

get_object_or_404(SomeModelName,id=id)

CodePudding user response：

You can choose one of these methods to get the object related to id you entered:

get_object_or_404() function:

from django.shortcuts import get_object_or_404

model_object = get_object_or_404(ModelName, id=id)

.get_or_create() method:

model_object, created = ModelName.objects.get_or_create(id=id)

.filter() and .first() methods:

model_object = ModelName.objects.filter(id=id).first()

CodePudding user response：

Yourtablename.object.get(pk=id)

Or use filter
