我创建了一个表单来更新用户的配置文件，但是当我运行它时，没有任何错误，但是当我尝试打开页面时，表头出现，但没有出现UpdateBioForm。其次，我想知道如何创建一个大型文本框来存储某人的传记。Django - Modelform not rendering

Models.py

class UserProfile(models.Model): 
    user = models.OneToOneField(User) 
    biography = models.CharField(max_length = 255, default = '') 
    city = models.CharField(max_length=100, default = '') 
    website = models.URLField(default='') 
    image = models.ImageField(upload_to='profile_image', blank=True) 
    def setdefault(self, default_path='/profile_image/Default.jpg'): 
     if self.image: 
      return self.image 
     return default_path 
    def __str__(self): 
     return self.user.username

Forms.Py

class UpdateBioForm(forms.ModelForm): 
    class Meta: 
     model = UserProfile 
     fields = (
      'biography', 
      'city', 
      'website' 
     ) 
    def save(self, commit=True): 
     savedBio = super(UpdateBioForm, self).save(commit=False) 
     savedBio.biography = self.cleaned_data['biography'] 
     savedBio.city = self.cleaned_data['city'] 
     savedBio.website = self.cleaned_data['website'] 
     if commit: 
      savedBio.save() 
     return savedBio

Views.py

def update_bio(request): 
    if request.method == 'POST': 
     form = UpdateBioForm(request.POST, instance=request.user) 
     if form.is_valid(): 
      form.save() 
      return redirect('/') 
    else: 
     form = UpdateBioForm(instance=request.user) 
    args = {'form':form} 
    return render(request, 'accounts/update_bio.html')

urls.py

url(r'^profile/updatebio/$',views.update_bio, name='update_bio'),

update_bio.html

{% extends 'base.html' %} 
{% block body %} 
<div class="container"> 
    <h1>Update Biography</h1> 
    <form method="post"> 
     {% csrf_token %} 
     {{ form.as_p }} 
     <button type="submit">Submit</button> 
    </form> 
</div> 
{% endblock %}

回答：

您没有传递任何情况下你render()方法 - 定义args但不要做与该变量什么。将其更改为：

args = {'form':form} 
return render(request, 'accounts/update_bio.html', context=args) # <-- You're missing context
