Property has many lists. List has many properties. Users can add properties to a list , here user must be owner of those properties which he want to add.
Here is my code:
class List < ActiveRecord::Base has_many : propertyships has_many :properties, :through => :propertyships end class Propertyship < ActiveRecord::Base belongs_to : list belongs_to :property end class Property < ActiveRecord::Base has_many : propertyships has_many :lists, :through => :propertyships end
<%= simple_form_for(@list, url: add_property_list_path, :method => :put) do |f| %> <%= f.collection_check_boxes(:property_ids, @user_all_properties, :id, :street_address) %> <%= f.submit "Add Property" %> <% end %>
resources :lists do member do put 'add_property' end end
def add_property @list = List.find(params[:id]) @list.update_attributes(list_params) end private def list_params params.require(:list).permit(:name, :user_id, property_ids: ) end
when I checked properties and I click “Add property” button as other user , its add checked properties but remove old properties that I have in that particular list. what a I doing wrong??
