Does validates_presence_of work for foreign keys?
I have a Service model the belongs to Agent I then have validates_presence_of :title, :locator, :agent_id, :user_id in my model.
But I can create Services with out choosing an agent and it saves and validates just find. Why??? Why doesn't the validates_presence_of prohibit the service from being created without an agent?
Here is my relevant create code: unless params[:agent]||params[:agent] == "-- Select an Agent --" # check if an agent was choosing agent = Agent.find(params[:agent]) #find the agent @service.agent_id = agent.id #assign the agent to the service end if @service.save #do stuff
How do I make sure that the service has an agent before it is created?
Thanks in advance, K
