Using an existing database of another Rails application in a new Rails application
I'm new to Rails. I had created a Rails application earlier and also collected a few data records in the development database. Suppose, I create a new Rails application and I prefer to use the existing development database of the 1st Rails application in my newly created Rails application, how do I do that?
No correct solution
Just change the file config/database.yml and set the database name.
your database.yml should look like this:
development: host: localhost adapter: mysql database: your_database_name [just the name, not the path] username: your_username password: your_password test: ... production: ...
You need to change the database name in the database.yml file. The seconnd problem you run into is migrations.
I would copy the migrations form your previous application over so that you maintain migration integrity with version numbers and rolling back if that is needed.
Also, if you are seeing development.locs - that locs refers to the table_name, which in restful context is usually also coincidentally the name of the controller.
