I have upgraded to the latest Ruby on a Padrino application and I am having errors with active record when creating a new object. It's validating a number (an ISBN) as 4 bytes. The error is:
9781407005416 is out of range for ActiveRecord::Type::Integer with limit 4
How do I tell a Ruby active record class to use 8 byte limit?
I am not talking about running a migration, the table is already bigint(20).
I thought the following would work:
class Book < ActiveRecord::Base
attribute :isbn, :integer, :limit => 8
end
I then get errors on find_by and as_json for the ISBN field:
#<NoMethodError: undefined method 'type_cast_for_database' for :integer:Symbol
I turned the 'isbn' method into a new instance variable instead of changing the column of the attribute created by the active record adapter.
I know the column has a limit, but not sure how to access the type of the column to update it.
Falling a solution to the type setting is there a way to skip the validation that is now happening in the active record ensure_in_range.
Is there a way to change the built in DEFAULT_LIMIT = 4 of class Integer < Value from my app? This is related to the following changes in Ruby but I have no access to changing the Padrino source.
How do I tell a Ruby active record class to use 8 byte limit? AFAIK, AR should figure this out directly from the database metadata.
First, restart the app if not done already - column types are cached. Next, I would verify that AR actually sees the column as you expect. Try this to make sure it is doing what you think:
p Book.columns.select{ |col| col.name == 'isbn'}
Look at the @range and @limit under @cast_type.

Does this mean that you overrode the isbn getter? If so, what exactly does that code look like?
