Subject: Rails questions

Spent some time this weekend working on a Rails application.  It's great
stuff, coming from a php/mysql "hack it together" background.  But I have a
couple questions...

1)
I have a controller called "houses".  In that, there's an action called
"modify".  modify's view (modify.rhtml) has a form with an action
"save_house".  When the user hits submit, modify gets called with id
save_house (i.e. /houses/modify/save_house).  What I want to have happen is
the action "save_house" called.  I have another action "new", and new.rhtml
has a form with action "create_house", and when the user hits submit, the
action "create_house" is called, which is what I want to have happen.  I'm
not sure why that's not the case with modify.

2)
has_and_belongs_to_many question:  I have a model "House" that
has_and_belongs_to_many "Amenity".  Is there a "Best Way(tm)" to display
this relationship in the controller/view?  The way it works currently:

houses_controller#new:
    @amenities=Amenities.find_all

new.rhtml:
    (loops through @amenities, spits out checkboxes.)

house_controller#create:
    @house = House.new(@params["house"].save
    @house.amenities.clear
    @params["amenities"].each do |amenity|
        # @params["amenities"] is an array of amenity id's that the user
selected
        temp_amenity = Amenities.new
        temp_amenity.id = amenity
        @house.amenities << amenity
    end

This seems pretty clumsy to me.


Thanks for any input!
