Hey All,
I was walking through the tutorial part 1 on polls. When i executed "*python
manage.py sql polls*" i got this stack trace
*

*django.db.utils.DatabaseError: (1046, 'No database selected')*
I've been googling and everyone says that i don't have access to the mysql
database for "polls" but i was able to access the database when i entered
*mysql
-u root -h localhost polls*
This is how my settings.py looks like for database:
*DATABASES = {*
*'default': {*
*'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2',
'mysql', 'sqlite3' or 'oracle'.*
*'NAME': '', # Or path to database file if
using sqlite3.*
*'USER': 'root', # Not used with sqlite3.*
*'PASSWORD': '', # Not used with sqlite3.*
*'HOST': 'localhost', # Set to empty string
for localhost. Not used with sqlite3.*
*'PORT': '', # Set to empty string for
default. Not used with sqlite3.*
*}*
*}*
Also, here is to show that i actually selected the database
*mysql> use test*
*Database changed*
*mysql> GRANT ALL ON test.* TO 'testuser'@'localhost';*
*Query OK, 0 rows affected (0.08 sec)*
*
*
*mysql> quit*
*Bye*
my mac has been finicky with databases on RoR and so i am trying to switch
to django. Does anyone know where the problem is?
