Rails nicht Flash-Nachrichtenschlüssel nach Aktion zerstört

Question

Ich benutze Rails 4 und haben vier Methoden an meinem application_controller.rb zur Einstellung Flash-Mitteilungen in Rails

def exclusion_info_for model_name 
    flash[:notice] = "#{model_name.to_s.capitalize} has been deleted." 
end 

def creation_notice_for model_name 
    flash[:notice] = "#{model_name.to_s.capitalize} has been created." 
end 

def update_notice_for model_name 
    flash[:notice] = "#{model_name.to_s.capitalize} has been updated." 
end 

def error_notice 
    flash[:error] = "An unexpected error has it occurred" 
end 

Aber die flash Einstellung bei exclusion_notice_for verloren, nachdem der Umleitung bestehen bleiben die Aktion destroy. Die anderen Methoden funktionieren normal.

Der Regler

class CustomersController < ApplicationController 
    respond_to :html 

    def new 
    respond_with @customer = customer 
    end 

    def create 
    if @customer = Customer.create(customer_attrs) 
     creation_notice_for :customer 
    else 
     error_notice 
    end 
    respond_with @customer, location: "/" 
    end 

    def show 
    respond_with @customer = customer 
    end 

    def index 
    respond_with @customers = Customer.all 
    end 

    def edit 
    respond_with @customer = customer 
    end 

    def update 
    if @customer = customer.update(customer_attrs) 
     update_notice_for :customer 
    else 
     error_notice 
    end 
    respond_with @customer, location: "/" 
    end 

    def destroy 
    if @customer = customer.destroy() 
     exclusion_info_for :customer 
    else 
     error_notice 
    end 
    respond_with @customer, location: "/" 
    end 

    private 

    def customer 
    id ? Customer.find(id) : Customer.new 
    end 

    def customer_attrs 
    params.require(:customer).permit(:name) 
    end 

end

Dies ist die application.rb Datei

class ApplicationController < ActionController::Base 
    # Prevent CSRF attacks by raising an exception. 
    # For APIs, you may want to use :null_session instead. 
    protect_from_forgery with: :null_session

    def error_notice

    end 

end

Flashing Methode werden alle Ihre Aktionen arbeiten einfach hinzufügen 'created' oder 'updated' String wie in der Destroy-Methode.

Sie haben Fehler Can't verify CSRF token authenticity

Sie diese Methode in application.rb Datei setzen kann, um alles zu reparieren.

protect_from_forgery with: :exception, if: Proc.new { |c| c.request.format != 'application/json' } 
protect_from_forgery with: :null_session, if: Proc.new { |c| c.request.format == 'application/json' } 

protected 

def info_flashed (model_name, action) 
    flash[:notice] = "#{model_name.to_s.capitalize} has been #{action}." 
end 

Kontroller

def destroy 
    if @customer = customer.destroy 
     info_flashed (@customer, 'deleted') 
    else 
     error_notice 
    end 
    respond_with @customer, location: "/" # you need to redirect correct path. 
    end
