How to change the time format in django in a generic class based view

Is there a way to change the format for datetime fields when using CreateView or UpdateView? I am trying to get the form to accept dates in the form of something like "2016-12-29 03:49 PM". I know the format should be '%Y-%m-%d %I:%M %p', and this tests just fine in the shell. I just don't know how to get it working using CreateView or UpdateView, but it seems that it should be able to be done.

You need to update your Form Class to accept other input formats. Your form should look something like this:

class YourForm(ModelForm):
    date_of_birth = DateTimeField(input_formats='%Y-%m-%d %I:%M %p')
    class Meta:
        model = YourModel

However, it's probably better to put all of your acceptable input formats in a variable and call it from your settings.py like this:

settings.py
DATE_INPUT_FORMATS = [
    '%Y-%m-%d %H:%M:%S',
    '%m/%d/%Y %H:%M:%S',
    '%Y-%m-%d %I:%M %p',
]

forms.py
class YourForm(ModelForm):
    date_of_birth = DateTimeField(input_formats=settings.DATE_INPUT_FORMATS)
    class Meta:
        model = YourClass

Lastly, I wouldn't leave it up to the user to type a date in manually anyways (assuming this view is for humans), give them a DateTime widget to select it for them. You can find info about the widgets here: https://docs.djangoproject.com/en/1.10/ref/forms/widgets/

and info about the datetime Form Field here: https://docs.djangoproject.com/en/1.10/ref/forms/fields/#datetimefield
