Django:访问表单中的请求。py清洁功能

Hi * people,

嗨*人,

In my clean function in forms.py, I would like to save automatically some information in a session variable. However, I do not seem to get access to the request variable.

在我干净的功能中。py，我想在一个会话变量中自动保存一些信息。但是，我似乎无法访问request变量。

All examples for handing over the request variable are based on function based views, but here I am using a class based view.

所有提交请求变量的例子都基于基于基于函数的视图，但是这里我使用的是基于类的视图。

My forms.py:

我的forms.py:

from django import forms
from item.models import Item

class CreateItemForm(forms.ModelForm):
    class Meta:
        model = Item
        fields = ('name', 'description')

    def __init__(self, request, *args, **kwargs):
        self.request = request
        super(CreateItemForm, self).__init__(*args, **kwargs)

    def clean(self):
        cleaned_data = super(CreateItemForm, self).clean()
        if cleaned_data.get("address"):
            self.request.session['name'] = cleaned_data.get("name") 
        else:
            raise forms.ValidationError(_('Oops, can\'t find location.'))
        return self.cleaned_data

My views.py:

我的views.py:

from django.views.generic.edit import FormView
from item.forms import CreateItemForm

class ItemCreate(FormView):
    form_class = CreateItemForm 
    template_name = 'item/item_create.html' 
    success_url = 'http://www.google.com'

What is the best way to hand over the request variable from the views.py to forms.py?

从视图中提交请求变量的最佳方式是什么?py forms.py吗?

Thank you for your answer.

谢谢你的回答。

You can overwrite the FormMixin's get_form_kwargs method to add the request for to the form's init parameters:

您可以改写FormMixin的get_form_kwargs方法，将请求添加到表单的init参数中:

class ItemCreate(FormView):
     def get_form_kwargs(self):
         kwargs = super(ItemCreate, self).get_form_kwargs()
         kwargs.update({
             'request' : self.request
         })
         return kwargs

Overriding the form.get_initial() works for me

重写form.get_initial()对我来说是可行的

class ItemCreate(FormView):
    def get_initial(self):
        init = super(ItemCreate, self).get_initial()
        init.update({'request':self.request})
        return init

And in the clean we can access it with form.initial dict

在清洁中我们可以用表格来访问它。最初的东西

class sampleForm(forms.Form):
    ...
    ...
    def clean(self):
    user_request = self.initial['request']

By the way, we don't need to pop the extra args like suggested above.

顺便说一下，我们不需要像上面建议的那样弹出额外的args。
