Question

In Django I have form that is using the SplitDateTimeField which is set to have an initial value as shown below. When try view the template containing the form I get ValueError: “strftime format ends with raw %.”

# forms.py

class DiscountForm(Form):
    title = CharField(widget=TextInput(), required=True)
    description = CharField(widget=Textarea(), required=True)
    fineprint = CharField(widget=Textarea(), required=True)
    start = SplitDateTimeField(
        input_date_formats='%m/%d/%Y',
        input_time_formats='%I:%M %p',
        initial= lambda: dt.datetime.now(),
        required=True
    )
    end = SplitDateTimeField(
        input_date_formats='%m/%d/%Y',
        input_time_formats='%I:%M %p',
        initial= lambda: dt.datetime.now() + dt.timedelta(days=30),
        required=True
    )
    limit = IntegerField(min_value=0, initial=0, required=True)

# relevant in settings.py 

USE_I18N = False
USE_L10N = False
USE_TZ = True

DATETIME_INPUT_FORMATS = ('%m/%d/%Y %I:%M %p')
DATE_INPUT_FORMATS = ('%m/%d/%Y')
TIME_INPUT_FORMATS = ('%I:%M %p')

Here is my traceback: http://dpaste.org/y55eV/

Any guidance is greatly appreciated. Thank you

The arguments input_date_formats and input_time_formats need to be lists or tuples, not strings (see SplitDateTimeField in documentation). The error may be caused that it is now iterating over characters instead of multiple input formats.

Try changing the code to the following:

start = SplitDateTimeField(
    input_date_formats=('%m/%d/%Y',),
    input_time_formats=('%I:%M %p',),
    initial= lambda: dt.datetime.now(),
    required=True
)
end = SplitDateTimeField(
    input_date_formats=('%m/%d/%Y',),
    input_time_formats=('%I:%M %p',),
    initial= lambda: dt.datetime.now() + dt.timedelta(days=30),
    required=True
)
