Getting Rails to work with an existing database instead of a new one

All of the Rails tutorials I’ve looked at seem to revolve around creating a new database and then making the contents of the database accessible through the web page. The URL http://localhost:3000/users gives you access to the user list after you enter the following commands:

rails generate scaffold User name:string email:string
rake db:create:all
rake db:migrate

But what if you already created the user database with data in it? What is the alternative procedure for providing access to the user database at http://localhost:3000/users ?

that comment will generate controller, model and migration(used to create table), you can generate them separately

3

see this command will not generate the database this will generate the table name user , if you want to change the database go to the database.yml to change the database name.

Just delete the migration file generated, and don't run the rake commands. Alternatively just use generate model and generate controller and write the rest yourself (or just write it all yourself). If you use generate model then again delete the migration generated.

That all assumes the existing table is rails compatible of course.
