Question

我使用Django和通用视图“django.views.generic.create_update.create_object” 我有一个模型表单，我传递给通用视图：

url(r'^add$', create_object, {'template_name':'tpl.html','form_class':MyModelForm,'post_save_redirect':'/'},name = 'add'),

我需要在我的ModelForm.save方法中获取当前用户.. 但我找不到方法，请帮我找到方便的方法？

class MyModelForm(forms.ModelForm):



class Meta:
    model = MyModel


def save(self,*a,**b):
    MyModel.save(user=request.user) #how can i get here request.user?

class Meta: model = MyModel def save(self,*a,**b): MyModel.save(user=request.user) #how can i get here request.user?

通常的问题是 - 如何在传递给通用视图的表单中使用请求参数。

Answer 1

你可能会破解一些东西将请求注入到表单实例化中，但为什么你会烦恼？通用视图仅作为基本要求的快速简便解决方案。一旦你开始需要大规模的自定义，你也可以自己编写实际的视图。毕竟，这不是很多代码。

Answer 2

看那个：

url(r'^add$', create_object_with_request, {'template_name':'tpl.html','form_class':MyModelForm,'post_save_redirect':'/'},name = 'add'),

，

def create_object_with_request(request, *args, **kwargs):
    def inject_request(fun):
        def helper(*args, **kwargs):
            return fun(*args, request=request, **kwargs)
        return helper
    kwargs['form_class'] = inject_request(kwargs['form_class'])
    return create_object(request, *args, **kwargs)

所以你已经将请求传递给了你的类构造函数。或者您可以将其添加为属性：

def create_object_with_request(request, *args, **kwargs):
    def inject_request(fun):
        def helper(*args, **kwargs):
            res = fun(*args, **kwargs)
            res.request = request
            return res
        return helper
    kwargs['form_class'] = inject_request(kwargs['form_class'])
    return create_object(request, *args, **kwargs)

Answer 3

thnx这有帮助）我有一些问题这个语法和_meta attr我完成了这个

def create_object_with_request(request, *args, **kwargs):



def inject_request(fun):

    def helper(*args, **kwargs):
        finst = fun(*args, **kwargs)
        finst.request = request
        return finst

    helper._meta = fun._meta
    return helper
kwargs['form_class'] = inject_request(kwargs['form_class'])
return create_object(request,*args, **kwargs)

def inject_request(fun): def helper(*args, **kwargs): finst = fun(*args, **kwargs) finst.request = request return finst helper._meta = fun._meta return helper kwargs['form_class'] = inject_request(kwargs['form_class']) return create_object(request,*args, **kwargs)

使用Django中的通用视图将请求传递给模型表单
