[Django]-Django – prevent duplicates for users

✅

  1. Pass user to form – add him to form kwargs by adding this method to view:

    def get_form_kwargs(self, *args, **kwargs):
    kwargs = super(Create, self).get_form_kwargs(*args, **kwargs)
    kwargs['user'] = self.request.user
    return kwargs

  2. Get user in form and check:

    def __init__(self,*args, **kwargs):
    self.user = kwargs.pop('user') # this line added
    super(AlbumCreateForm, self).__init__(*args, **kwargs)
    self.fields['name'].widget = forms.TextInput(
       attrs={'placeholder': 'name'})

def clean(self):
    if Album.objects.filter(user=self.user).exists():
        raise forms.ValidationError('Error description')
