Creating User Specific Participation Pages in Rails 4 -

i have 3 models; examinations, participation , user. connected has many through relationship - , participation model joint model.

i can list participations or show specific participation (see controller below) - goal create page named "my participations" - users can see participations. participation model has "user_id" field purpose don't know how create kind of page or method in controller.

thanks in advance.

here model structure:

examination.rb =>

class examination < activerecord::base   has_many :participations   has_many :users, :through => :participations    has_many :bookings   has_many :exam_centers, :through => :bookings end 

participation.rb =>

class participation < activerecord::base   belongs_to :user   belongs_to :examination end 

user.rb =>

class user < activerecord::base   has_many :participations   has_many :examinations, :through => :participations end 

as can see i'm having "participation" join model between examination , user models. have has many through rich relationship.

participations_controller.rb =>

#encoding: utf-8  class participationscontroller < applicationcontroller    before_filter :authenticate_user!   before_action :set_participation, only: [:show, :edit, :update, :destroy]   before_filter :get_examination    def get_examination     @examination = examination.find(params[:examination_id])   end    def index     @participations = @examination.participations     respond_to |format|       format.html       format.csv { send_data @participations.to_csv }       format.xls # { send_data @examinations.to_csv(col_sep: "\t") }     end   end    def show     @participation = @examination.participations.find(params[:id])   end    def new     @participation = participation.new   end    def edit   end    def create     @participation = @examination.participations.new(participation_params)     @participation.user = current_user      respond_to |format|       if @participation.save         format.html { redirect_to [@examination, @participation], notice: 'başvuru işleminiz başarıyla tamamlandı! lütfen başvurunuzu kontrol ediniz ve onaylayınız. onaylanmamış başvurular geçersiz sayılacaktır!' }         format.json { render action: 'show', status: :created, location: [@examination, @participation] }       else         render 'new'         format.html { render action: 'new' }         format.json { render json: @participation.errors, status: :unprocessable_entity }       end     end   end    def update     respond_to |format|       if @participation.update(participation_params)         format.html { redirect_to [@examination, @participation], notice: 'başvurunuz başarıyla güncellendi! lütfen başvurunuzu kontrol ediniz ve onaylayınız. onaylanmamış başvurular geçersiz sayılacaktır!' }         format.json { head :no_content }       else         format.html { render action: 'edit' }         format.json { render json: participation.errors, status: :unprocessable_entity }       end     end   end    def destroy     @participation.destroy     respond_to |format|       format.html { redirect_to examination_participations_path }       format.json { head :no_content }     end   end    def approve_application     @participation = @examination.participations.find(params[:id])     @participation.is_approved = true     @participation.save     redirect_to examination_participation_path, notice: 'kaydınızı onayladınız! tebrikler!'   end    private     # use callbacks share common setup or constraints between actions.     def set_participation       @participation = participation.find(params[:id])     end      # never trust parameters scary internet, allow white list through.     def participation_params       params.require(:participation).permit(:user_id, :examination_id, :payment_status, :language_preference, :exam_center_preference, :disability)     end end 

schema structure =>

  create_table "examinations", force: true |t|     t.string   "name"     t.string   "shortname"     t.datetime "exam_date"   end    create_table "participations", force: true |t|     t.integer  "user_id"     t.integer  "examination_id"     t.boolean  "payment_status"     t.string   "language_preference"     t.string   "exam_center_preference"   end    create_table "users", force: true |t|     t.string   "email",                  default: "", null: false     t.string   "first_name",             default: "", null: false     t.string   "last_name",              default: "", null: false     t.string   "id_number"   end 

routes =>

devise_for :users  resources :examinations   resources :participations     member       :update_profile_information       :approve_application     end   end end 

you can create new controller, myparticipationscontroller example, , create index action display participations current user.

app/controllers/my_participations_controller.rb

class myparticipationscontroller < applicationcontroller   before_filter :authenticate_user!    def index     @participations = current_user.participations   end end 

config/routes.rb

resources :my_participations, only: [:index] 

you may remove index action in participationscontroller if needed.
