  destroy(@model || instance_context(id))
end

#get(id = nil, action = nil) ⇒ Object

  • If id and action are provided, call the method action (if implemented).

  • If only id is provided, load the show_context and call show.

  • Otherwise, load the new context and call list

# File 'lib/airbed.rb', line 38

def get(id=nil,action=nil)

  # we have id and action ... call arbitrary action
  if !id.blank? and !action.blank?
    model = instance_context(id)
    
    # special case
    action = (action == 'new' ? 'new_action' : action)
    send(action,model)

  elsif !id.blank?
    model = show_context(id)
    show(model)

  else
    list = list_context
    list(list)
  end
end

#post(id = nil) ⇒ Object

Maps from POST requests to restful actions. Also supports “exotic” methods PUT and DESTROY (via the _verb parameter).

  1. POST with an id is undefined

  2. POST with no id loads new_context and calls create.

  3. _verb == ‘put’ + id delegates to put the handler

  4. _verb == ‘destroy’ + id deletgates to the destroy handler

    end

  end
