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

问题描述

我创建了一个继承 UpdateView 的类视图.我已经指定了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，那么我想在表单中禁用它.我不知道如何做到这一点.

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/'

推荐答案

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 Form 类 - 因为这是由 UpdateView 处理的.

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

使字段只读:

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

Django 1.9 的注意事项

Django 1.9 内置了 禁用 选项.使用它可以让你跳过额外的 clean 方法.

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)
