Djangoでユーザ固有のオブジェクトを作成する

Question

ユーザがいるdjangoプロジェクトを作成しようとしていて、作成した書籍のタイトルを追加できます。ユーザーだけが自分の書籍のタイトルを閲覧することができます。私はmodels.py、forms.py、& views.pyでどのようにしてクラスを作成し、ユーザとその書籍のタイトルを結びつけるのだろうかと思っていました。ここまで私がこれまで持っていたことがあります。

models.py

from django.db import models 
from django.contrib.auth.models import User 

class Scripter(models.Model): 
    user = models.OneToOneField(User) 
    name = models.CharField(max_length=30) 

    def __unicode__(self): 
     return self.name 

class Title(models.Model): 
    author = models.ForeignKey(Scripter) 

    def __unicode__(self): 
     return self.script_title 

forms.py

from django import forms 
from django.contrib.auth.models import User 
from django.forms import ModelForm 
from scripters.models import Scripter, Title 

class RegistrationForm(ModelForm): 
    username = forms.CharField(label=(u'User Name')) 
    email = forms.EmailField(label=(u'Email Address')) 
    password = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False)) 
    password1 = forms.CharField(label=(u'Verify Password'), widget=forms.PasswordInput(render_value=False)) 

    class Meta: 
     model = Scripter 
     exclude = ('user',) 

    def clean_username(self): 
     username = self.cleaned_data['username'] 
     try: 
      User.objects.get(username=username) 
     except User.DoesNotExist: 
      return username 
     raise forms.ValidationError("User Name has been taken!") 

    def clean(self): 
     if self.cleaned_data['password'] != self.cleaned_data['password1']: 
     raise forms.ValidationError("The passwords did not match") 
     else: 
      return self.cleaned_data 

class LoginForm(forms.Form): 
    username = forms.CharField(label=(u'Username')) 
    password = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False)) 

class CreateScript(ModelForm): 
    title = forms.CharField(label=(u'Script Title')) 

    class Meta: 
     model = Title 

    def clean_title(self): 
     title = self.cleaned_data['title'] 
     return title 

views.py

       email = form.cleaned_data['email'], 
       password = form.cleaned_data['password'] 
      ) 
      user.save() 
      scripter = Scripter(user=user, name=form.cleaned_data['name'])

      ) 
      title.save() 
      script = Title(script_title=title_form.cleaned_data['title']) 
      script.save() 

      return HttpResponseRedirect('/edit/') 
     else:

    else: 
     title_form = CreateScript() 
     context = {'title_form': title_form} 
     return render_to_response('NewScript.html', context, context_instance=RequestContext(request)) 

Answer 1

私が何を求めていることは、私はタイトルのリストを得るのですかだと思います特定のユーザーが所有しています。

これは逆の関係を使用してかなり簡単です：

scripter.title_set.all() 

はあなたのスクリプターのインスタンスが所有するすべての書籍を取得します。
