Ruby, Rake, Mysql - creating database

How to do? I tried something like:

RAILS_ENV=production rake db:create db:load

in file /lib/tasks/load_tasks.rake and this file I tried in terminal as rake db:migrate, but I am getting errors about syntax etc.

I entered into terminal this command (I saw it in tutorial):

rails generate scaffold Account user_name:string description:text premium:boolean \
   开发者_如何学Python   income:integer ranking:float fee:decimal birthday:date login_time:time

And this made me file 20110518181941_create_accounts.rb

How can I create database table - I thought the command above will create me database in mysql... I am now a bit confusing, what to do?

Which rule is playing here rake db:migrate?

I think you are getting this error because your syntax is wrong, please put && between sentences:

RAILS_ENV=production rake db:create && db:schema:load

or do it in separated lines

RAILS_ENV=production rake db:create
RAILS_ENV=production rake db:schema:load

the first command will create the database, the second command will Load the db/schema.rb file into the database

And finally you need to run your migration:

RAILS_ENV=production rake db:migrate

to create your Accounts table.

BTW if you run:

rake -T

you can see the list of rake tasks and their descriptions.

Hope this helps.
