    <p><strong>First</strong><br> I love Django, I like it because with just few lines of describing Model I get full CURD web app.<br> Now I am having app that need one-to-many relationship and it is not working as I am expecting.</p> <p>I question is based on: <a href="https://stackoverflow.com/questions/6928692/how-to-express-a-one-to-many-relationship-in-django">How to express a One-To-Many relationship in Django</a></p> <p>So this is my code:</p> <p><strong>models.py</strong></p> <pre><code>from django.db import models class Dude(models.Model): name = models.CharField(blank=False, null=False, max_length=100, unique=True) def __unicode__(self): return u"%s" % self.name class PhoneNumber(models.Model): dude = models.ForeignKey(Dude) number = models.CharField(blank=False, null=False, max_length=100, unique=True) </code></pre> <p><strong>admin.py</strong></p> <pre><code>from django.contrib import admin from TestingDjango.apps.one_to_many.models import Dude, PhoneNumber class DudeAdmin(admin.ModelAdmin): pass list_display = ('name',) class PhoneNumberAdmin(admin.ModelAdmin): pass list_display = ('dude', 'number') admin.site.register(Dude, DudeAdmin) admin.site.register(PhoneNumber, PhoneNumberAdmin) </code></pre> <p>When I operate admin web UI I need to add Dude and after that I need to go to PhoneNumber, and for each number for same dude I need to add new row (and select same dude again and again).</p> <p>What I was expecting was following: - when I am addend new dude, in same page, I will have "+" button where I could add multiple numbers for one dude. And after that click save. When I look at dude I will see all numbers for that dude, now I need to go to PhoneNumber to see all numbers per dude.</p> <p>How to do it ?<br> Is it even possible with just editing admin.py or I need to write my own view for that ?<br> If I need to write my own view for that, please give some guidelines how to do it ? </p>

    1. COYou can use `Inline Models` for this. https://docs.djangoproject.com/en/1.3/ref/contrib/admin/#django.contrib.admin.InlineModelAdmin They are exactly what you need.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
