How do I define an ARRAY column in a Sequel Postgr

问题:

I am creating a Sequel migration to create a new table in my PostgreSQL database. I want to define a String array column, which PostgreSQL supports.

My migration looks like this:

create_table :venues do
  primary_key :id

  String      :reference                                , :null => false
  String      :name                                     , :null => false
  String      :description                              , :null => false
  String[]    :type                                     , :null => false

  DateTime    :created_at                               , :null => false
  DateTime    :updated_at                               , :null => false
end

How can I define something like text[] in my migration?

回答1:

You just use the column method and specify the type as a string: column :type, "text[]"
