méthode non définie `write_inheritable_attribute 'pour ContactsController: Classe

Question

J'ai mis à jour ma version de Rails de 3.2.13 à Rails 4.2.6. Dans l'ancienne version, ils ont utilisé map_fields plugins où dans mon contrôleur de contacts:

class ContactsController < ApplicationController 
    require 'map_fields' 
    map_fields :mapper, ['First Name','Last Name', 'Email', 'Notes'], :file_field => :file, :params => [:contact] 

    def create 
    @user = User.find(params[:user_id]) 
    @contact = @user.contacts.create(contact_params) 
    respond_to do |format| 
     if @contact.save 
     format.json { render :json => { :notice => 'Contact was successfully created!',:redirect => user_contacts_url} } 
     format.html { redirect_to(user_contacts_url(@user), :notice => 'Contact was successfully created!', :type => 'success') } 
     else 
     format.json { render :json => {:redirect => false} } 
     format.html { render :action => "edit" } 
     end 
    end 
    end 
    def import 
    @contact = Contact.new 
    end 
    def mapper 
    @contact = Contact.new(params[:contact]) 
    count = 0 

    if fields_mapped? 
     mapped_fields.each do |row| 
     params[:contact] = {"user_id" => @current_user.id, "firstname" => row[0], "lastname" => row[1], "notes" => row[3], "email" => row[2].try(:strip)} 
     contact = Contact.new(params[:contact]) 

     if contact.save 
      count = count + 1 
     end 
     end 

     if count > 0 
     flash[:notice] = "#{count} Contact(s) created" 
     redirect_to :action => :index 
     else 
     flash[:notice] = "No contact was created..." 
     redirect_to :action => :index 
     end 

    else 
     @best_row = @rows[1] 
     render 
    end 

    rescue MapFields::InconsistentStateError 
     flash[:error] = 'Please try again' 
     redirect_to :action => :import 
    rescue MapFields::MissingFileContentsError 
     flash[:error] = 'Please upload a file' 
     redirect_to :action => :import 
    end 

end 

quand je lance le code que je reçois l'erreur

Ceci est mon fichier routes.rb:

J'ai suivi les mêmes étapes que celles que vous avez indiquées dans issue 1, mais j'obtiens cette erreur. S'il vous plaît aider.

Answer 1

J'ai également eu le même problème, je l'ai résolu en supprimant rmagic.

gem uninstall rmagick 
gem cleanup 

pack puis
