[Solved] Attempted relative import beyond toplevel package in django

Try this in your models:

#Remove the import statement: from blog.models import sighinmodel
#Then, inside your model
user = models.ForeignKey('blog.sighinmodel' , on_delete = None)

Also, I would like to point out that this is not the correct way of importing other modules in your models.py .

You should do like this:

from appname.models import ModelName
#for importing from another module's models.

There is no need for relative path names in import statements in Django. from appname.module import function/class works fine for nearly all the cases until cyclic redundancy occurs, in which you have to take one among many methods. One is the way I mentioned above:

Method 1: Simply put this inside the ModelClass. Don’t import anything.

user = models.ForeignKey('blog.sighinmodel' , on_delete = None)

Method 2(when cyclic import condition is not arising)

from blog.models import sighinmodel
class SomeModel(models.Model): 
    user = models.ForeignKey(sighinmodel , on_delete = None)

NOTE: The above will work only if a cyclic import isn’t occurring. In case the cyclic import condition is occurring, switch back to the first method of declaration.

Hope this helps. Thanks.
