Django表单：TimeField验证 [英] Django Forms: TimeField Validation

问题描述

我觉得我在这里缺少一些明显的东西。我有一个Django表单，其中包含一个 TimeField 。我想要允许像10:30 AM这样的时间，但是我无法接受这种输入格式或使用％P格式（它具有一个附注说这是一个专有扩展名，但不说来自哪里。以下是我的表单代码的要点：

  calendar_widget = forms.widgets.DateInput（attrs = {'class'：'date-选择'}，format ='％m /％d /％Y'）
 time_widget = forms.widgets.TimeInput（attrs = {'class'：'time-pick'}）
 valid_time_formats = [ '％P'，'％H：％M％A'，'％H：％M％A'，'％H：％M％a'，'％H：％M％a'] 
 
 class EventForm（forms.ModelForm）：
 start_date = forms.DateField（widget = calendar_widget）
 start_time = forms.TimeField（required = False，widget = time_widget，help_text ='ex：10： 30AM'，input_formats = valid_time_formats）
 end_date = forms.DateField（required = False，widget = calendar_widget）
 end_time = forms.TimeField（required = False，widget = time_widget，help_text ='ex：10： 30AM'，input_formats = valid_time_formats）
 description = forms.CharField（widget = forms.Textarea）
  

任何时候我提交10:30 AM，我得到验证错误。底层模型有两个字段，event_start和event_end，没有时间字段，所以我不认为问题在那里。我错过了什么愚蠢的事情？

解决方案

您需要使用％I来解析指定％p的时间。请参阅这里的指令表中的第一个注释： http：//docs.python。 org / library / time.html＃time.strftime 。

I feel like I'm missing something obvious here. I have a Django form with a TimeField on it. I want to be able to allow times like "10:30AM", but I cannot get it to accept that input format or to use the "%P" format (which has a note attached saying it's a "Proprietary extension", but doesn't say where it comes from). Here's the gist of my form code:

calendar_widget = forms.widgets.DateInput(attrs={'class': 'date-pick'}, format='%m/%d/%Y')
time_widget = forms.widgets.TimeInput(attrs={'class': 'time-pick'})
valid_time_formats = ['%P', '%H:%M%A', '%H:%M %A', '%H:%M%a', '%H:%M %a']

class EventForm(forms.ModelForm):
    start_date = forms.DateField(widget=calendar_widget)
    start_time = forms.TimeField(required=False, widget=time_widget, help_text='ex: 10:30AM', input_formats=valid_time_formats)
    end_date = forms.DateField(required=False, widget=calendar_widget)
    end_time = forms.TimeField(required=False, widget=time_widget, help_text='ex: 10:30AM', input_formats=valid_time_formats)
    description = forms.CharField(widget=forms.Textarea)

Any time I submit "10:30AM", I get a validation error. The underlying model has two fields, event_start and event_end, no time fields, so I don't think the problem is in there. What stupid thing am I missing?

解决方案

You need to use %I to parse the hours when you specify %p. See the first note under the table of directives here: http://docs.python.org/library/time.html#time.strftime.
