self.new(name, default, sql_type = nil, null = true)

Instantiates a new column in the table.

name is the column’s name, such as supplier_id in supplier_id int(11). default is the type-casted default value, such as new in sales_stage varchar(20) default 'new'. sql_type is only used to extract the column’s length, if necessary. For example 60 in company_name varchar(60). null determines if this column allows NULL values.

Parameters

default req
sql_type opt = nil
null opt = true
