I think you are better off handling this converts at the template level using the tag date. For example, I see you pass the date and time variables to the template. Just pass them unconverted and later in the template wherever they appear do this:
{% if condition %}
{{date|date:"DATE_FORMAT"}}
{{value|time:"TIME_FORMAT"}}
{% endif %}
where "TIME_FORMAT" is the actual format that you want the date to be showed and condition is the condition that needs to be met.
If you absolutely need to do this within the view method, then you can use the module django.utils.dateformat like this:
from django.utils.dateformat import DateFormat, TimeFormat
formatted_date = DateFormat(date_variable)
formatted_date.format('Y-m-d') # substitute this format for whatever you need
formatted_time = TimeFormat(time_variable)
formatted_date.format('h') # substitute this format for whatever you need
Use that class wherever you want to format your date_variable and time_variable with the proper format string for them.
Also, about your views' code. You can't just return a string in the middle of a view method like you do:
if request.method == 'POST':
if user.date_format == '0':
date=datetime.datetime.strptime('%m/%d/%Y').strftime('%d/%m/%Y')
return date
That will throw an exception if the request method is POST. Besides, what date are you formatting there? You need to format your report.manual_date. I don't see that anywhere in the code. Apply what I said above to the variable you want to format depending on your settings and pass that variable to the tempalte_context when you return.
I hope it helps!
