如何以django形式获取列表发布数据？(How to get list post data in django forms?)

我的表单序列化如下：

server_ids=6&server_ids=9

并且在使用getlist的视图中可以获得列表数据成功：

request.POST.getlist('server_ids')

但是如何在django.forms类中定义 'server_ids'？

例如，在我的表单类中：

class MyForm(forms.Form): server_ids = forms.MultiValueField()

我尝试过models.MultipleChoiceField，TypedMultipleChoiceField，MultiValueField ......但是表单有效获取错误。

my form serialize like this:

server_ids=6&server_ids=9

and in views using getlist can get list data successful:

request.POST.getlist('server_ids')

but How can I define 'server_ids' in django.forms class?

For example, in my forms class:

class MyForm(forms.Form): server_ids = forms.MultiValueField()

I tried models.MultipleChoiceField, TypedMultipleChoiceField, MultiValueField...But the form valid get error.

最满意答案

我想你的意思是：

self.data.getlist('server_ids')

您可以在表单类中调用它。 例如，用clean方法

以下是您的其他问题的示例：

SERVER_CHOICES = ( ('1', '1'), ('2', '2'), ('3', '3'), ) server_ids = forms.MultipleChoiceField( widget=forms.SelectMultiple, choices=SERVER_CHOICES)

如果您查看有关Django小部件和表单的文档，这也很有帮助

I suppose you mean that:

self.data.getlist('server_ids')

You can call it in a form class. e.g. in a clean method

Here is an example for your other question:

SERVER_CHOICES = ( ('1', '1'), ('2', '2'), ('3', '3'), ) server_ids = forms.MultipleChoiceField( widget=forms.SelectMultiple, choices=SERVER_CHOICES)

It is also helpful if you take a look at the documentations about Django widgets and forms
