Re: Introducing myself and my first question

[Ariel E. Isidro]

Hi Martin,

I myself am new in Django, here's one tutorial I believe is worth visiting
when setting up your environment:

Good luck

After git, pythonanywhere is a simple way to deploy and publish.

What if you define your views to use only the fields that you need?

Re: moving from sqlite3 to mysql

[Ariel E. Isidro]

1. before exiting mysql, you should grant permission to a user,i.e.
grant all privileges on django_1.* to username@'localhost' identified by
'userpassword'
replace username, userpassword with your own
2. exit mysql console
3. modify settings.py to add your username, password, host (localhost), and
port (3306)
4. run python manage.py syncdb

Re: moving from sqlite3 to mysql

[Ariel E. Isidro]

"Or can I create the database, (presumably directly in the shell), and then
empty it, as these instructions say, and that will take care of it? I
frankly didn't understand why I would need to 'empty' a new and empty
database, but that's what it says. "

With sql lite, everything will be created for you.
While with MySQL,  you should create the database directly in the shell,
and this should give you an empty database.  The Django tables will be
created after configuring your settings, and running  syncdb.
