request.POST ['time']必须为datefield（）

Question

I'm very new to django, maybe I'm asking something very elemental.

I have the following code :

crush.time = request.POST['time']

this 'time' post value is a timefield and I need to process as a time value, but all I got is that crush.time is a string, and then I got the following error when I try to process:

'unicode' object has no attribute 'hour'

Answer 1

The POST multidictionary contains strings - it does not know about python data types. You have to parse it into a datetime object. look at the datetime documentation.

Answer 2

Assuming your ' time ' field is in the form H:M:S or H:M, then you could create a django form to do the parsing work for you (keep in mind you don't necessarily need to output the form):

In your forms.py:

from django import forms

class BasicTimeForm(forms.Form):
    time = forms.TimeField()

In your view:

if request.method == 'POST': 
    form = forms.BasicTimeForm(request.POST)
    if form.is_valid():
        crush.time = form.cleaned_data['time']

After a post, crush.time should now contain a datetime.time.

只需使用Python datetime库将其转换为时间对象即可：

datetime.datetime.strptime(request.POST['time'], '%H:%M:%S').time()
