Django的1.6.5 - 「無效的字面INT（）與基地10」 regirstration形式

Question

我想實現一個登記表，但我得到了以下錯誤：

invalid literal for int() with base 10:'alex'

我之前實現它，它運作良好！但現在不行！我的表單包含'ImageField'，我遵循this和this文檔和教程。我刪除了Imagefield，但錯誤仍然存​​在！我在SO上看過類似的問題，但他們沒有解決問題。

該錯誤發生在username字段中。

感謝您的任何意見。

我form.py是：

class RegisterationForm(ModelForm): 
    # user name 
    user_name = forms.CharField(max_length=32, label="Username account") 
    # password 
    password = forms.CharField(label='Password', widget=forms.PasswordInput(render_value=False)) 
    re_password = forms.CharField(label='Repeat Password', widget=forms.PasswordInput(render_value=False)) 
    # email 
    email = forms.EmailField(label='Email Address') 

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

    def clean_user_name(self): 
     user_name = self.cleaned_data['user_name'] 
     try: 
      User.objects.get(username=user_name) 
     except User.DoesNotExist: 
      return user_name 
     raise forms.ValidationError(u'UserName Error') 


    def clean(self): 
     password = self.cleaned_data['password'] 
     password1 = self.cleaned_data['re_password'] 
     if password != password1: 
      raise forms.ValidationError(u'Passwords are not equal') 
     return self.cleaned_data 

和我view.py負責我register.html：

def register_view(request): 
    if request.user.is_authenticated(): 
     return HttpResponseRedirect('/profile/') 
    if request.method == 'POST': 
     form = RegisterationForm(request.POST, request.FILES) 
     if form.is_valid(): 
      user = User.objects.create_user(username=form.cleaned_data['user_name'], 
              password=form.cleaned_data['password'], 
              email=form.cleaned_data['email']) 
      user.save() 

      return HttpResponseRedirect('/profile/') 
     else: 
      return render_to_response('register.html', {'form': form}, context_instance=RequestContext(request)) 
    else: 
     form = RegisterationForm() 
     context = {'form': form} 
     return render_to_response('register.html', context, context_instance=RequestContext(request)) 

最後我register.html：

{% extends 'bases/home_base.html' %} 
{% block content %} 
    <form method="POST" action=""> 
     {% csrf_token %} 
     {% if form.errors %} 
      <p> 
       Fix the errors! 
      </p> 
     {% endif %} 
     <div id="register_div">  
      {% comment %} User Name {% endcomment %} 
      {% if form.user_name.errors %}<p>{{ form.user_name.error_messages }}</p>{% endif %} 
      <p><label for="user_name">User Name:</label></p> 

      <p>{{ form.user_name }}</p> 


      {% comment %} password {% endcomment %} 
      {% if form.password.errors %}<p>{{ form.password.error_messages }}</p>{% endif %} 
      <p><label for="password">password:</label></p> 

      <p>{{ form.password }}</p> 

      {% comment %} re_password {% endcomment %} 
      {% if form.re_password.errors %}<p>{{ form.re_password.error_messages }}</p>{% endif %} 
      <p><label for="re_password">re_password:</label></p> 

      <p>{{ form.re_password }}</p> 

      {% comment %} email {% endcomment %} 
      {% if form.email.errors %}<p>{{ form.email.error_messages }}</p>{% endif %} 
      <p><label for="email">email:</label></p> 

      <p>{{ form.email }}</p> 
     </div> 
     <input type="submit"/> 
    </form> 

{% endblock %} 

UPDATE

我model.py：

class WebsiteUser(models.Model): 
    # username 
    user_name = models.OneToOneField(User, max_length=32) 
    # birth day 
    birth_day = models.DateField() 
    # email address 
    email = models.EmailField(max_length=50) 
    # watched movies 
    watched_movies = models.ManyToManyField(Movie, related_name='watched', blank=True, null=True) 
    # rated movies 
    rated_movies = models.ManyToManyField(Movie, related_name='rated', blank=True, null=True) 
    # recent movies 
    recent_movies = [] 

    def __unicode__(self): 
     return " ".join([self.first_name, self.last_name])

Answer 1

WebsiteUser.user_name是OneToOneField，從而它存儲相關對象的主關鍵字的值。你試圖在那裏存儲用戶名，這是行不通的。
