I have following subscription creating system, right now when I`m selection
available subscription groups(Marketing, Sales) action Save Subscription
create this two subscriptions:
@subscriptions = current_user.subscriptions
> @apps = App.all
> if request.post?
> if params[:subscription] and params[:subscription][:app_id]
> params[:subscription][:app_id].each do |app_id|
> Subscription.create_unique({user_id: current_user.id, app_id:
> app_id})
> end
> redirect_to root_path
> end
> end
# app_menu.html.erb
<%= form_for :subscription do |f| %> # this form goes to app_menu action
> above
>
<ul>
>
<% @apps.each do |app| %>
>
<li> <%= check_box_tag app.id, current_user.access?(app) %><span>
>
<%= app.name %></span>
>
</li>
>
<% end %>
>
</ul>
>
<%= f.submit %>
>
<% end %>
>
So I can only add new Subscriptions(in this particular example i can only
add Engineering).

How to refactor that action to be able also destroy subscription groups by
uncheck them(ex. I want to unsubscribe from Marketing group) ?
So when I choose Marketing and Enginnering then
params[:subscription][:app_id] will be equal [marketing.id, engineering.id]
Relations:
*App*
> has_many :subscriptions
> has_many :users, through: :subscriptions
> *User*
> belongs_to :app
> has_many :subscriptions, :dependent => :destroy
> *Subscription*
> belongs_to :user
> belongs_to :app
So the issue is how to find which apps has been unchecked? And maybe is a
way how to refactor that action. Pleas help :)
