要获得12小时时间格式，您将使用以下内容：

输入（这是格式列表Django用于验证）：

  field = TimeField（input_formats =（'％I：％M％p'，... ，...））
 

输出（这是Django将用于显示时间值的格式） ：

  field = TimeField（widget = TimeInput（format ='％I：％M％p'））
 ％I表示12小时时钟格式，而％H表示24小时时钟格式。

$ b

此外，input_formats的默认列表可以在每个语言环境formats.py文件中找到。 Django将input_formats列表中的第一个格式用作时间字段的默认输出格式。

i want to allow users to be able to choose between am and pm with my django timefield

Currently if I enter:

11:00 AM

, i get a form error: "Enter a valid time."

If I enter:

11:00

the form validates with no problem.

I also tried:

class RemindersForm(forms.ModelForm):

    remdinder = forms.TimeField(input_formats='%H:%M %p',)

    class Meta:
        model = NotificationPreference
        fields = (
                  'reminder', 
                  )

This changes the input format to:

11:00:00

and still gives me the above validation error.

What am I doing wrong?

To get a 12hr time format you would use the following:

For input (This is the list of formats Django uses in validation):

field = TimeField(input_formats=('%I:%M %p',...,...))

For output (This is the format Django will use to display time values):

field = TimeField(widget=TimeInput(format='%I:%M %p'))

The %I indicates a 12 hour clock format whereas the %H indicates a 24 hour clock format.

Additionally, the default list of input_formats can be found in each locales formats.py file. Django uses the first format in the input_formats list as the default output format for time fields.
