for a single-table inheritance in rails, how do I know the 'type' when creating a record?
- by Angela
I have several models which are very similar: Contact_Emails, Contact_Letters, Contact_Calls -- and I think life could be easier making them into a Single Table Inheritance called Contact_Event.
However, the way I have it set up now is when something is created for a Contact_Email, I have a dedicated controller that I call and know that I am passing the arguments that are approrpriate. For example, new_contact_email(contact, email).
I then have:
Emails.find(email.contact_id), etcera, all very specific to that Model.
I'm not sure how I extract the class/models to use.
For example, I currently have the following because I have separate controllers for each model:
def do_event(contact, call_or_email_or_letter)
model_name = call_or_email_or_letter.class.name.tableize.singularize
link_to( "#{model_name.camelize}", send("new_contact_#{model_name}_path",
:contact => contact,
:status => 'done',
:"#{model_name}" => call_or_email_or_letter ) )
end
What I really want is to:
link_to("#model_name.camelize}", send("new_contact_event_path(contact,call_or_email_or_letter)"
