Seirie - thanks for the response! Matt - you are right about the typos - featureable_type in Features would be referring to "property" rather than "property.id" and Feature_Data should have a field "value." The ERD is correct. I set this up as polymorphic since at least two more models will have Features: Units and Rooms.
I broke out Features into two models (Features and Feature_Data) for two reasons: I wanted to normalize the feature titles and wanted to have data_type which could record whether the data is an integer, boolean, string, etc. (since I assume I will have to store everything in Feature_Data as a string and convert back using rails) - a real pain! Thinking through it again, since I would have an "unlimited" number of features available through a polymorphic association, maybe I should make all the data boolean and rework as such: (is there a more graceful way?) Properties id yadda yadda Properties_Features property_id feature_id Features id featurable_type (polymorphic - property, unit, or room) title value (boolean, always true?) -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
