Question

I am trying to set up a Ruby on Rails project by following the instructions on their website. I am using MySQL database. When I try to create a project using the rails -d mysql demo command. I just get the default usage: instructions. Something like below…

-d, [--database=DATABASE]   # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db)
                            # Default: sqlite3

I am not sure what is the correct syntax based on --database?

I am using the instructions on this site, is it something related to version? I am using Rails 3.0.3

Answer 1

I suggest doing the following.

$ sudo gem install rails mysql
$ rails demo
$ cd demo
$ edit database.yml
# change database type from sqlite3 to mysql
$ rails server -p 4000
# open a web browser to localhost:4000 and see if you see some, else look at the error log in the terminal
