I am not able to make migrations to the following file?

Time:03-08

I am trying to create the migration of the following models.py code but the following error is occuring ???(I am learning Web-Devlopment from CS50-Web Devlopment Courese) Can Anyone help me solve the error is I have very little knowledge about django, sqlite and as well as Web-devlopment.

    from django.db import models
    class Flight(models.Model):
        origin = models.CharField(max_length=64)
        destination = models.CharField(max_length=64)
        duration = models.IntegerField()

The error is as follows:

CodePudding user response:

You are importing include from wrong module.Probably from xml.etree.ElementInclude

So change

from xml.etree.ElementInclude import include

to

from django.urls import include

in your airline/urls.py file.
