Importing csv into Ruby on Rails application error -


i trying able import csv of courses consist of course name , professor. i'm having error i've been trying fix research, i'm coming blank. appreciate if take , me see doing incorrectly.

in routes.rb

get 'import/index' post 'import/index'  resources :courses   collection { post :import } end

in course.rb:

def self.import(file)     csv_text = file.read(file.path)     csv = csv.parse(csv_text, headers: true)      csv.each |row|         course.create!(row.to_hash)     end  end

in courses_controller.rb

def import   course.import(params[:file])   redirect_to course_path, notice: "courses imported!" rescue    redirect_to 'index', notice: "invalid file format" end

in import index view:

<p>import course csv:</p> <%= form_tag import_courses_path, multipart: true %>   <%= file_field_tag :file %>   <%= submit_tag "import courses" %> <% end %>

my rake routes:

controller#action         import_index    /import/index(.:format)                     import#index                      post   /import/index(.:format)                     import#index       import_courses post   /courses/import(.:format)                   courses#import              courses    /courses(.:format)                          courses#index                      post   /courses(.:format)                          courses#create           new_course    /courses/new(.:format)                      courses#new          edit_course    /courses/:id/edit(.:format)                 courses#edit               course    /courses/:id(.:format)                      courses#show                      patch  /courses/:id(.:format)                      courses#update                      put    /courses/:id(.:format)                      courses#update                      delete /courses/:id(.:format)                      courses#destroy

i generated import controller views. in retrospect, not best way - should have made view in course instead. getting no data received "err_empty_response" because redirecting /courses/import, doesn't have view. want route courses page instead. i'm confused , feel might have convoluted situation. if can see why csv import not working correctly, please let me know! thank you.

edit: here error i'm getting log:

course_path -> should path single, specific course - aren't passing course show... or should courses_path
