Railsowe "link_to" wywoływane z funkcji JS ...and Datatables.net

BSorbus · January 22, 2015, 5:56pm

przepraszam za zamieszanie #insurance-groups …i #companies…
Bo mam kilka takich.

BSorbus · January 22, 2015, 6:15pm

Aby możliwe było żonglowanie w definicji ajax: {…}
type GET/POST koniecznie musiałem ustawić: ServerSide znowu na true, gdyż w przeciwnym wypadku w WEBricku widzidziałem cały czas GET/ …

Dla wywołania jak zaproponowałeś pojawia się:

rozumiem, że jest to związane z:

class CompaniesController < ApplicationController
before_action :authenticate_user!

def index
respond_to do |format|
format.html
format.json{ render json: CompaniesDatatable.new(view_context, { only_for_current_user_id: @current_user.id }) }
end
end
…
end

jest jeszcze setting:

"sServerMethod": "POST"

Kalaf · January 22, 2015, 6:19pm

So close! Wystarczy teraz żeby Twój index odpowiadał na POST a nie GET,

resources :companies, except: [:index, :create] do
  post 'index', on: :collection
end

coś takiego w routes.rb

BSorbus · January 22, 2015, 6:20pm

A to jest wewnątrz definicji ajax: { …}, czy poza nią?

BSorbus · January 22, 2015, 6:24pm

routes czy resources ?

Kalaf · January 22, 2015, 6:24pm

resources oczywiście ;p

Kalaf · January 22, 2015, 6:26pm

A, tylko zmień na insurance, w AJAX’ie też, bo widzę, że edytowałeś posta wcześniej

BSorbus · January 22, 2015, 6:29pm

jest jeszcze setting:

“sServerMethod”: “POST”

A to jest wewnątrz definicji ajax: { …}, czy poza nią?

Kalaf · January 22, 2015, 6:32pm

Duuude, już masz POST, popatrz w logi, wystarczy tylko żeby wywoływało odpowiednią akcję w odpowiednim kontrolerze. Musisz wywalić POST /costam matchujący do akcij create i dodać POST /costam matchujący do index

BSorbus · January 22, 2015, 6:41pm

no /cośtam tak średnio działa

Coś chyba w tym route.rb namieszaliśmy

Kalaf · January 22, 2015, 6:42pm

Po kolei - do jakiego kontrolera ma się odnosić Twoja tabela? CompaniesController czy coś z insurance?

BSorbus · January 22, 2015, 6:50pm

Zostanmy przy Company

  resources :companies, except: [:index, :create] do
    post 'index', on: :collection
  end

companies_url POST /companies/index(.:format) companies#index
new_company_url GET /companies/new(.:format) companies#new
edit_company_url GET /companies/:id/edit(.:format) companies#edit
company_url GET /companies/:id(.:format) companies#show
PATCH /companies/:id(.:format) companies#update
PUT /companies/:id(.:format) companies#update
DELETE /companies/:id(.:format) companies#destroy

I teraz wywołanie:

http://127.0.0.1:3000/companies/ nic nie daje. zgłasza błąd

Kalaf · January 22, 2015, 6:51pm

A, przepraszam:

resources :companies, except: [:index, :create] do
  post :index, on: :collection
end

rake routes | grep compa
companies POST   /companies(.:format)             companies#index

BSorbus · January 22, 2015, 6:54pm

                companies POST   /companies/index(.:format)                                              companies#index
              new_company GET    /companies/new(.:format)                                                companies#new
             edit_company GET    /companies/:id/edit(.:format)                                           companies#edit
                  company GET    /companies/:id(.:format)                                                companies#show
                          PATCH  /companies/:id(.:format)                                                companies#update
                          PUT    /companies/:id(.:format)                                                companies#update
                          DELETE /companies/:id(.:format)                                                companies#destroy

Kalaf · January 22, 2015, 6:55pm

Zamień 'index' na :index, najwidoczniej symbole są inaczej traktowane jak pasują do standardowych railsowych akcji

BSorbus · January 22, 2015, 7:01pm

po zmianie:

                companies POST   /companies(.:format)                                                    companies#index
              new_company GET    /companies/new(.:format)                                                companies#new
             edit_company GET    /companies/:id/edit(.:format)                                           companies#edit
                  company GET    /companies/:id(.:format)                                                companies#show
                          PATCH  /companies/:id(.:format)                                                companies#update
                          PUT    /companies/:id(.:format)                                                companies#update
                          DELETE /companies/:id(.:format)                                                companies#destroy

i

a dla http://127.0.0.1:3000/companies

WEBric:

ActionController::RoutingError (No route matches [GET] “/companies”):

.i pojawia się znany ekran:
Routing Error
No route matches [GET] “/companies”

Zacznijmy może od tego, że wybierając link w menu wybieram:
companies_path … a to jest chyba domyślnie metoda GET

Kalaf · January 22, 2015, 7:06pm

Pewnie polegaleś wcześniej na GET /companies żeby wejść na stronę. Tak na szybko:

  resources :companies do
    post 'datatables_index', on: :collection
  end

data-source="<%= datatables_index_companies_path(format: :json) %>"

Kontroler

def datatables_index
  respond_to do |format|
    format.json{ render json: CompaniesDatatable.new(view_context, { only_for_current_user_id: @current_user.id }) }
  end
end

Ależ przeszkód

BSorbus · January 22, 2015, 7:09pm

… i na koniec i tak nie zadziała

…daj chwilkę na wprowadzenie zmiany

BSorbus · January 22, 2015, 7:10pm
