how to add a column to my table Users.

because I ran the migration, I have to do something like:

rails generate migration AddShowmsgColumnToUsers show_msg:boolean

and then: 

rake db:migrate

but I’m not sure about “AddShowmsgColumnToUsers“. how can I know how it suppose to be? why not: AddShow_msgColumnToUsers? if the problem was pluralization and singularization, I can run the rails console and check that, but how can I know about the uppercase letter: ShowMsg/Show_msg/Show_Msg/Showmsg? is there a command that helps me to check it?

    In answer to your first question, it doesn’t matter, as long as the table name is correct – Rails uses the arguments you specify for the columns rather than the name of the migration.

    Also, you should only really be asking one question at a time… 😉
