Question

I am new to Django and I getting some difficulties in implementing this model in Django:

Until now I have the model working without the table “Positions”, and looks like this:

from django.db import models
import datetime

class Category(models.Model):
    n_category = models.CharField(max_length=100)

class Directory(models.Model):
    website_name = models.CharField(max_length=200)
    website_url = models.URLField()
    categories = models.ManyToManyField(Category)

My question is, How can I add the table “Positions” to this model?

Please give me a clue.

Best Regards.

Answer 1

Create a the model Position which has ForeignKeys to Categories and Directory and all the other data needed. And then use the through argument for the ManyToManyField. This is described in the Django documentation

Example (which if haven’t tested):

class Position(models.Model):
    website_postiton = models.IntegerField()
    category = models.ForeignKey('Category')
    directory = models.ForeignKey('Directory')

class Category(models.Model):
    n_category = models.CharField(max_length=100)

class Directory(models.Model):
    website_name = models.CharField(max_length=200)
    website_url = models.URLField()
    categories = models.ManyToManyField(Category, through=Position)
