I want to create a commenting model with a twist. I want there to be multiple commenting columns like on hunch.com, except that a user can decide how many columns there should be. Also, a user can decide the title for each column.
This is rather dynamic, so how would I set up my tables for this?
Since you cannot really change the attributes of a model, if you want to create dynamic model attributes, you can have 3 models :
Now, you can add as many attributes are you want (Attribute is the static representation of an attribute). Then, a user can have many attributes through user_attributes.
