Django UpdateView禁用某些字段 [英] Django UpdateView disable some fields

问题描述

我已经做了一个继承UpdateView的类视图。我已经指定了应该从中构建表单的字段和模型。现在说如果我有一个字段电子邮件，那么我想要禁用它的形式。我没有线索可以做到这一点。

  class UserUpdate（UpdateView）：
 model = Users 
 fields = ['email'，'first_name'，'last_name'，'birth_date'] 
 template_name ='users_update_form.html'
 success_url ='/ index /'
  




解决方案

要隐藏：

  class UserUpdate（UpdateView）：
 model = Users 
 fields = ['first_name'，'last_name'，'birth_date'] 
 template_name ='users_update_form.html'
  

在这种情况下，无需创建单独的表单类 - 由 UpdateView 处理。

b
$ b

  class UserForm（forms.ModelForm）：
 class Meta：
 model = Users 
 fields = ['email'，'first_name'，'last_name'，'birth_dat e'] 
 email = forms.CharField（widget = forms.TextInput（attrs = {'readonly'：'readonly'}））
 
 def clean_email（self）：
 return self.initial ['email'] 
 
 
 class UserUpdate（UpdateView）：
 model = Users 
 form_class = UserForm 
  

Django 1.9的注释

Django 1.9有一个 disabled 选项内置。使用此选项可以跳过其他清洁方法。

  class UserForm（forms.ModelForm）：
 class Meta：
 model = Users 
 fields = ['email'，'first_name'，'last_name'，'birth_date'] 
 email = forms.CharField（disabled = True）
  

I have made a class view inheriting UpdateView. I have specified the fields and models from which the forms should be built. Now say if i have a field email, then I want to disable it in the form. I have no clues as to how it can be done.

class UserUpdate(UpdateView):
    model = Users
    fields = ['email', 'first_name', 'last_name', 'birth_date']
    template_name = 'users_update_form.html'
    success_url = '/index/'

解决方案

To hide it:

class UserUpdate(UpdateView):
    model = Users
    fields = ['first_name', 'last_name', 'birth_date']
    template_name = 'users_update_form.html'

In this case there is no need to create a separate Form class - as this is handled by the UpdateView.

To make the fiel readonly:

class UserForm(forms.ModelForm):
    class Meta:
        model = Users
        fields = ['email', 'first_name', 'last_name', 'birth_date']
    email = forms.CharField(widget=forms.TextInput(attrs={'readonly':'readonly'}))

def clean_email(self):
    return self.initial['email']


class UserUpdate(UpdateView):
    model = Users
    form_class = UserForm

Note for Django 1.9

Django 1.9 has a disabled option built in. Using this allows you to skip the additional clean method.

class UserForm(forms.ModelForm):
    class Meta:
        model = Users
        fields = ['email', 'first_name', 'last_name', 'birth_date']
    email = forms.CharField(disabled=True)
