Impossible de trouver l'utilisateur avec id = # <ActiveRecord :: Relation :: ActiveRecord_Relation_User: 0x2eb9b58>

Question

Je reçois cette erreur lorsque je clique sur 'modifier':

Couldn't find User with id=#<ActiveRecord::Relation::ActiveRecord_Relation_User:0x2eb9b58> 

ActiveRecord::RecordNotFound in UsersController#edit 

Voici le UsersController:

class UsersController < ApplicationController 
    before_action :set_user, only: [:index, :show, :edit, :create, :update, :destroy] 
    ... 
    def edit 
    @user = User.find(params[:id]) #the error points to this line. 
    end 
    ... 
end

Jetez un coup d'oeil au fichier de vue de la commande d'édition, si edit.html.erb. Vous essayez probablement d'appeler quelque chose sur un modèle de jointure, au lieu de l'objet réel que vous essayez d'afficher.
