选择最适合你的:

1

is_private = request.POST.get('is_private', False);

如果请求中存在is_private key。POST is_private变量将等于它，如果不是，那么它将等于False。

2

if 'is_private' in request.POST:
    is_private = request.POST['is_private']
else:
    is_private = False

3

from django.utils.datastructures import MultiValueDictKeyError
try:
    is_private = request.POST['is_private']
except MultiValueDictKeyError:
    is_private = False

First check if the request object have the 'is_private' key parameter. Most of the case's this MultiValueDictKeyError occurred for missing key in the dictionary-like request object. Because dictionary is an unordered key, value pair “associative memories” or “associative arrays” In another word. request.GET or request.POST is a dictionary-like object containing all request parameters. This is specific to Django. The method get() returns a value for the given key if key is in the dictionary. If key is not available then returns default value None.

你可以这样处理这个错误:

is_private = request.POST.get('is_private', False);

is_private = request.POST.get('is_private', False);

try:
    is_private = request.POST['is_private']
except MultiValueDictKeyError:
    is_private = False

我得到了'MultiValueDictKeyError'错误，而使用ajax与Django。只是因为在选择元素时没有输入“#”。像这样。

data:{ name : $('id_name').val(),},

然后我把'#'与id和问题解决了。

data:{ name : $('#id_name').val(),},

为什么不尝试在模型中定义is_private为default=False?

class Foo(models.Models):
    is_private = models.BooleanField(default=False)

你得到这个是因为你试图从字典中获取一个键，而它并不在那里。你需要先测试它是否在那里。

try:

is_private = 'is_private' in request.POST

or

is_private = 'is_private' in request.POST and request.POST['is_private']

这取决于你所使用的值。
