Appels AJAX dans Ruby: erreur 404

Question

Je suis nouveau du développement de ruby ​​et de Web, j'ai cherché beaucoup pour ce problème mais je n'ai pas encore compris.

J'ai un bouton :

<button type="button" class="btn btn-primary" onclick="add()">Add</button> 

qui appellent une fonction AJAX :

<script> 

function add() { 
    $.ajax({ 
     type : "get", 
     url : "civil_defence_alerts/checkError", 
     data: null, 
     success: function (data) { 
      alert(data); 
     } 

     } 

    ) 
} 
</script> 

Dans mon "civil_defence_alerts_controller" i défini une méthode nommée check_error:

def check_error 

    #Some code... 

end 

Maintenant, quand je clique sur le bouton l'appel ajax échoue parce que ne peut pas trouver la méthode check_error (erreur 404), j'ai essayé différentes configurations routes.rb ... Il me rend fou!

Merci les gars, et désolé pour mon anglais: D

EDIT, mon routes.rb:

MyApp::Application.routes.draw do 

    mount Ckeditor::Engine => '/ckeditor' 
    get 'site/index' 

    apipie 
    mount Browserlog::Engine => '/logs'

Answer 1

Ajouter l'itinéraire correspondant à votre méthode check_error:

resources :civil_defence_alerts do 
    collection do 
    ... 
    get 'check_error' 
    end 
end 

Et dans votre requête, vous devez passer l'URI d'itinéraire correspondant (comme vous l'avez défini dans l'option url de votre fonction ajax), quelque chose li ke:

function add() { 
    $.ajax({ 
    url: 'civil_defence_alerts/check_error', 
    success: function (data) { 
     alert(data) 
    } 
    }) 
} 

Notez que si la requête est GET, vous n'avez pas besoin de la spécifier.
