Create new Rails with mysql default on database.yml

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.

No need to post the results -- they're the same for everybody :slight_smile:

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. :slight_smile:

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 :slight_smile:

$ cat ~/.railsrc
–skip-bundle

-T
-d postgresql

$ time rails new test_3_2
Using --skip-bundle -T -d postgresql from /home/peterv/.railsrc
create

real 0m0.134s
user 0m0.108s
sys 0m0.024s

My special thanks to "7039def6 (Guillermo Iguaran " for this :slight_smile:

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
