python - 在 Django Admin 中使用带有自定义 __init__ 的表单

Question

我使用下面的代码在 Django Admin 中添加自定义表单:

class MyAdmin(admin.ModelAdmin):
    form = MyForm

但是，表单有一个重写的构造函数:

def __init__(self, author, *args, **kwargs):
    super(MyForm, self).__init__(*args, **kwargs)
    self.author = author

如何将 Admin 当前用户传递给表单构造函数？

Answer 1

像这样更改您的 MyAdmin 类:

class MyAdmin(admin.ModelAdmin):
    form = MyForm

    def get_form(self, request, **kwargs):
        form = super(MyAdmin, self).get_form(request, **kwargs)
        form.current_user = request.user
        return form

您现在可以通过访问 self.current_user 来访问 forms.ModelForm 中的当前用户。

def __init__(self, author, *args, **kwargs):
    super(MyForm, self).__init__(*args, **kwargs)
    self.author = author
    # access to current user by self.current_user
