I have been struggling for quite sometime with this. Is there any way to configure the Model to store user defined value in the inheritance_column instead of the default value (which is class_name) The problem I have is like this: I have a User model and there are different models which inherit from this like Admin, Premium, Professional, etc. Each of these inherited models are identified by a field named role_id in the users table and it c...

...ation from an existing database. The database has a "job" table that contains a "type" column. I''ve successfully overridden the names of the table and the name of the inheritance column by adding def self.table_name() ''job'' end Job.inheritance_column =''ruby_type'' to the job model, but then I''m unable to access the type field using the same "<td><%= job.type %></td>" construct that works for all the other fields in the .rhtml file. This always yields a value of "Job". I have to...

I''ve made a inheritance rework some weeks ago that would possible fix it since it only loads the inheritance support in the class that''ll use it. In STI case, it would load only if the class that descends directly from AR has been inherited and the column specified in the inheritance_column is available. People here told me to wait until next release so we can dig into this, but if you''ve interesting in testing it out send me a message and i''ll send you the patch. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscr...

Hi! I have a legacy table that has a column named "type" and need to remove this automatic subclassing by ActiveRecord. The api pages are vague about this, and I tried self.inheritance_column = "xtype" which seemed to get me half-way. In the validate_on_create method, the value of self.type was my model Class name. How would you disable this feature? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message b...

Hey, I have been looking at ActiveRecord''s serialization code, and noticed that ActiveRecord::XmlSerializer#serializable_attributes purposely excludes the STI inheritance column per ``options[:except] = Array(options[:except]) | Array(@record.class.inheritance_column).'''' Is there a particular reason for this? Would anyone be opposed to my writing a patch to have this attribute be included?

So by default to get STI, I would have something like: create_table :items do |t| t.column "type", :string t.column "title", :string end But if I want to store those type values in a separate table, such that I have ... create_table :items do |t| t.column "item_type_id", :string t.column "title", :string
