ruby on rails - Deleting an associated record through a remote_form -

i have built ruby on rails app lets users track workouts. user has_many workouts. in addition, user can create box (gym) if gym owner. users can associate box through membership resource.

i create association current_user remote form in /views/boxes/show.html.erb:

<% remote_form_for membership.new |f| %>    <%= f.hidden_field :box_id, :value => @box.id %>   <%= f.hidden_field :user_id, :value => current_user.id %>   <%= submit_tag "i member of box" , :class => '' %> <% end %> 

i want give current_user ability remove association. how structure link/form , should memberships_controller destroy action like?

below list of associations if helps: user

class user < activerecord::base   has_many :boxes   has_many :workouts, :dependent => :destroy end 

workout

class workout < activerecord::base   belongs_to :user   belongs_to :box end 

box

class box < activerecord::base   belongs_to :user   has_many :users, :through => :memberships   has_many :workouts, :through => :users   has_many :memberships end 

membership

class membership < activerecord::base   belongs_to :user   belongs_to :box end 

after have done changes suggested here, , assuming have obtained membership current_user , box using following code,

@membership = current_user.memberships.for_box(box).first 

create link user delete membership follows.

link_to 'delete membership', membership_path(@membership), :method => :delete 

membership controller should have destroy method looks following.

def destroy   @membership = membership.find(params[:id])   @membership.destroy end 

this assuming memberships controller restful , have map.resources :memberships in routes.
