search.html.haml:

.text-center   / no search results announcement/notification   - if @teachers.blank?     %h2 xin lỗi, hệ thống chúng tôi không có thông tin về giảng viên mà bạn muốn tìm.   - else     - @teachers.each |teacher|       %h2= link_to teacher.fullname, school_teacher_path(@school, teacher)       #note         %em           khoa #{teacher.department}, trường #{teacher.school.name} 

teachers_controller.rb:

class teacherscontroller < applicationcontroller   before_action :find_school, except: [:welcome, :search]   before_action :find_teacher, only: [:show, :edit, :update, :destroy]    def welcome   end    def show   end    def search     if params[:search].present?       @teachers = teacher.search(params[:search], fields: [:fullname])     else       @teachers = nil     end   end    def new     @teacher = @school.teachers.build   end    def create     @teacher = @school.teachers.create(teacher_params)     @teacher.save       redirect_to(@school)   end    def edit   end    def update     @teacher.update(teacher_params)     redirect_to(@school)   end    private    def find_school     @school = school.find(params[:school_id])   end    def find_teacher     @teacher = teacher.find(params[:id])   end    def teacher_params     params.require(:teacher).permit(:firstname, :lastname, :middlename, :department, :school_id, :fullname)   end end 

teacher.rb:

class teacher < activerecord::base   belongs_to :school   has_many :ratings    searchkick    def name     "#{lastname} #{middlename} #{firstname}"   end    def to_s     name   end end 

school.rb:

class school < activerecord::base   has_many :teachers, dependent: :destroy    # searchkick end 

routes.rb:

rails.application.routes.draw   devise_for :users    resources :schools     # collection     #   'search'     # end     resources :teachers       collection         'search'       end     end   end    resources :teachers     collection       'search'     end     resources :ratings   end    root 'teachers#welcome' end 

school_teacher_path called @school nil since find_school not used search. want replace @school teacher.school: school_teacher_path(teacher.school, teacher).
