Re: Advice please.

[Chucky Mada Madamombe]

Hi,

You have 2 options:

1. You can use choices
2. You can store data in a model, and then link with a foreign key.

First option is suitable for that data which wont change regularly e.g
gender..For data that changes or need to be updated regularly,  then use
second option.

You can use generic class based views and an html template.

Re: django doughts

[Chucky Mada Madamombe]

Hi,

In your mysite.urls, you must include the polls app urls as well. The error
is basically telling you that there is no url you are trying to request.

Re: best practice: using only url.py from the main project

[Chucky Mada Madamombe]

Hi yes it's bad practice.this is why:

The best point is to be able to reuse applications in different projects.
There will be problem if you are saving all your URLs in the
“projecturl.py” file. So best practice is to create an “url.py” per
application and to include it in your main projects url.py file.

Re: 404 error

[Chucky Mada Madamombe]

Hi,

404 error means Django searched your urls.py file and cannot find the
requested page. Take screen shot of your urls.py and views.py and
traceback. That may help us to figure out the problem.
