覆盖基于Django通用类的视图小部件 [英] Override a Django generic class-based view widget
问题描述
说我有一个基本的CreateView表单,允许新用户在网站上注册:
来自django .contrib.auth从django导入get_user_model
.http从django.views.generic导入HttpResponse
CreateView
User = get_user_model()
类Signup(CreateView):
模型=用户
字段= ['first_name','last_name','email','password']
$我刚刚尝试了一下,发现密码字段是用纯文本呈现的;我将如何覆盖视图,以便使用Forms.PasswordInput()代替? (我知道手动定义表单可能是最简单的方法,但是我很好奇您的操作方式。)解决方案您可以覆盖 get_form()
,然后修改表单以更改密码字段上的小部件:
从Django导入表单
类Signup(CreateView):
模型=用户
字段= ['first_name','last_name' ,电子邮件,密码]
def get_form(self,form_class):
form = super(Signup,self).get_form(form_class)
form.fields [ 'password']。widget = form.PasswordInput()
返回表格
但是偶数更好的方法是只创建一个自定义表单类。在自定义类中,只需在 Meta
类上设置 widgets
。像这样:
从Django导入表单
类SignupForm(forms.ModelForm):
类Meta:
模型=用户
字段= ['first_name','last_name','email','password']
小部件= {
'password':表格.PasswordInput()
}
class Signup(CreateView):
form_class = SignupForm
模型=用户
通常,您还将自定义表单类也放在forms.py文件中。
Say I have a basic CreateView form, like this, to allow new users to register on a site:
from django.contrib.auth import get_user_model
from django.http import HttpResponse
from django.views.generic import CreateView
User = get_user_model()
class Signup(CreateView):
model = User
fields = ['first_name', 'last_name', 'email', 'password']
I just tried this, and found that the password field is rendered in plain text; how would I go about overriding the view so that it uses forms.PasswordInput() instead? (I realise it's probably easiest to just define the form by hand, but I'm just curious about how you'd do that.)
解决方案 You could override get_form()
, and modify the form to change the widget on the password field:
from django import forms
class Signup(CreateView):
model = User
fields = ['first_name', 'last_name', 'email', 'password']
def get_form(self, form_class):
form = super(Signup, self).get_form(form_class)
form.fields['password'].widget = forms.PasswordInput()
return form
But an even better way would be to just create a custom form class. In the custom class just set widgets
on the Meta
class. Like this:
from django import forms
class SignupForm(forms.ModelForm):
class Meta:
model = User
fields = ['first_name', 'last_name', 'email', 'password']
widgets = {
'password': forms.PasswordInput()
}
class Signup(CreateView):
form_class = SignupForm
model = User
Usually you would put the custom form class in a forms.py file as well.
