ActiveRecord 'Column' class doc?

Rails
1

Can’t seem to find the Column class API documentation. For example,
content_columns
returns a list of Column objects, but where is the doc for this Column
class?

Thanks in advance,
Don McClean

I think its this:
http://api.rubyonrails.com/classes/ActiveRecord/ConnectionAdapters/Column.html

In irb prompt try:

SomeModel.content_columns.first.class

and see what you get.

Don’t know if this will help, but I had a similar situation recently and
someone suggested I use script\console to find out what I wanted to
know.
In my case I wanted to know what methods were valid on a field in my
Actors
table. So after starting script\console…

require ‘Actor’
Actor.columns.methods

returns the methods on all the fields.

Actor.columns_hash[‘field_name’].methods

returns the methods on the specified field

Actor.columns_hash[‘field_name’].limit # using one method as an example

returns the size of the specified field.

etc.

HTH,
Bill
