使用Space迁移Rails G的语法

Question

hello.

I'm trying to add a column called product_size to my order_items table in my schema.

Do I do this by:

$ rails g migration add_product_size_to_order_items

or

$ rails g migration add_product_size_to_OrderItem

or otherwise?

Thanks!

Answer 1

You should use

rails g migration add_product_size_to_order_items

then add also this line product_size:data_type

sample:

rails g migration add_product_size_to_order_items product_size:decimal
