ActiveRecord: List columns in table from console

Question

I know that you can ask ActiveRecord to list tables in console using:

ActiveRecord::Base.connection.tables

Is there a command that would li

Answer 1

• To list the columns in a table I usually go with this:
  Model.column_names.sort.
  i.e. Orders.column_names.sort

  Sorting the column names makes it easy to find what you are looking for.

• For more information on each of the columns use this:
  Model.columns.map{|column| [column.name, column.sql_type]}.to_h.

This will provide a nice hash. for example:

{
   id => int(4),
   created_at => datetime
}
