columns- Returns an array of
Columnobjects. columns_hash- Similar to the
columnsmethod but returns aHashusing column names as keys andColumnobjects as values. column_names- Returns a simple array of column names for the model.
The Column objects returned by columns and columns_hash can then be used to get information such as the data type and default values, for example:
User.columns_hash['email'].type
=> :string
User.columns_hash['email'].default
=> nil
User.columns_hash['email'].sql_type
=> "varchar(255)"
