Django中的隐藏字段不在clean_data中 [英] Hidden field in Django form not in cleaned_data

问题描述

我有这个表单：

  class CollaboratorForm（forms.Form）：
 user = forms.CharField label =Username，max_length = 100）
 canvas = forms.IntegerField（widget = forms.HiddenInput）
 .... 
 def clean_user（self）：
 user = self.cleaned_data ['user'] 
 canvas = self.cleaned_data ['canvas'] 
  

在视图中，我只是调用

 如果form.is_valid（）：
  

我收到错误：

  KeyError at / canvas / 1 / add-collaborator / 
'canvas'
  

根据firebug的价值正在发布，它似乎没有使我的清洁功能。我做错了吗？

编辑：发布数据

 画布1 
 csrfmiddlewaretoken 2cb73be791b32ca9a41566082c804312 
用户名称
  

EDIT2：我也愿意拿一个可以告诉我如何将主键发送到clean_user函数的答案，其中主键是上面的示例url中的/ 1 /。调用的视图中的函数是：

  def canvas_add_collaborator（request，pk）：
  

所以我想将pk发送到clean_user函数，这将解决我的问题，不需要隐藏的字段。

解决方案

您需要将方法名称更改为clean（），而不是clean_user（）。如果您只是验证用户字段，'canvas'不在clean_data中。

I have this form:

class CollaboratorForm(forms.Form):
    user = forms.CharField(label="Username",max_length=100)
    canvas = forms.IntegerField(widget=forms.HiddenInput)
    ....
    def clean_user(self):
        user = self.cleaned_data['user']
        canvas = self.cleaned_data['canvas']

In the view I'm simply calling

if form.is_valid():

I get the error:

KeyError at /canvas/1/add-collaborator/
'canvas'

According to firebug the value is posting, it's just doesn't seem to be making it to my clean function. Am I doing it wrong?

EDIT: Post data

canvas  1
csrfmiddlewaretoken 2cb73be791b32ca9a41566082c804312
user    username

EDIT2: I would also be willing to take an answer that could tell me how to send the primary key to the clean_user function, where the primary key is the /1/ in the example url above. The function in the view that is called is:

def canvas_add_collaborator(request, pk):

So I would want to send the pk to the clean_user function which would solve my problem by not needing the hidden field.

解决方案

You need to change the method name to clean(), not clean_user(). 'canvas' is not in the cleaned_data if you are just validating the user field.
