Hello, I'm trying to connect with a db in my app, but when I go on config/database.yml the default db is sqlite3, how can I put the mysql as default ?
# SQLite version 3.x # gem install sqlite3
`rails new --help`

Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time 'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the defaults values shown above in this help message.
Example: rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog. See the README in the newly created application to get going. felipe@Felipe:~/rails_projects$

No need to post the results -- they're the same for everybody 
Ok, but how I can make the mysql be default ?
Uh, well -- the reason I suggested running that command is that the
answer is in the output.
To make mysql the default when you run rails new you would have to modify the rails code somewhere (If you cannot figure out where on your own you should not try to modify it). To change the database driver used on this particular instance modify config/database.yml. Run rails new xx -d mysql to see what the values in that file should be.
In 3.2 you can define .railsrc with custom command line options that will always apply to rails new
Wow, that’s great
$ cat ~/.railsrc –skip-bundle
-T -d postgresql
$ time rails new test_3_2 Using --skip-bundle -T -d postgresql from /home/peterv/.railsrc create …

Ok, I create a new project with rails new new_project -d mysql, but it create as default database mysql2.. is correct ?
# MySQL. Versions 4.1 and 5.0 are recommended.
Yep. You need to use mysql2 gem in a rails 3 project to avoid encoding problems!
thx
