Question

in rails, we can generate the model like this

rails generate model post title:string body:text published:boolean

And the command has following syntax as per the rails guide

$ rails generate model
Usage: rails generate model NAME [field:type field:type] [options]

I am wondering if its possible to specify limit/length for each field as part of [options]? Further, what is the use of [options] parameter?

Answer 1

You can provide the limit with braces:

rails g model Session session_id:string{40} user_agent:string{200}
