Create a set column with database migration in rails

Question

I need to add a new column to my users table in the database. I want the type of the column to be set. The column represents the users gender. There should be two options to the set. One form Male "m" and the other for Female "f".

But I haven't found any documentation for adding a column with the set type.

How can I do this?

Answer 1

What db is used? mysql? If you're want to use SET datatype, you'll have to do it manually, as rails doesn't support it. However, I'd do just

t.string :gender, :limit => 1

for the sake of convenience.
