我的驗證正在工作，但消息不是

Question

我有一個類Ticket，如下所示。驗證工作，但消息說「Customer can't be blank」和「Builder can't be blank。另外，在創建時，url表示localhost/tickets。不應該是localhost/tickets/new？:customer和:builder用於從現有的構建器列表中進行選擇，或者輸入新的建設者，它的工作原理。我也取在誤差塊的Customer是清單，因爲我想不出還有什麼地方把它。

class Ticket < ActiveRecord::Base 
    belongs_to :installer, class_name: "Customer", foreign_key: :builder_id 

    validates :customer, presence: { message: "test" } 
    validates :builder, presence: { message: "test" } 

end 

和控制器。

class TicketsController < ApplicationController 
    # GET /tickets/new 
    def new 
    @ticket = Ticket.new 
    @builders = Customer.all 
    end 

    before_action :set_ticket, only: [:show, :edit, :update, :destroy, :remove] 

    def create 
    @ticket = Ticket.new(ticket_params) 

    # New Builder 
    if builder = params[:ticket][:builder] 
     @ticket.customer = builder 
     c = Customer.create(name: builder, color: params[:ticket][:color]) 
     @ticket.builder_id = c.id 
    elsif builder = params[:ticket][:customer] # Existing "Customer" 
     @ticket.builder_id = Customer.find_by_name(builder).id 
    end 

    if not params[:ticket][:color] # Existing Customer 
     color = Customer.find_by_name(builder).color 
     @ticket.color = color 
    end 
    calendar_date = Date.new(params[:ticket]["calendar_date(1i)"].to_i, 
          params[:ticket]["calendar_date(2i)"].to_i, 
          params[:ticket]["calendar_date(3i)"].to_i) 

    @ticket.calendar_order = Ticket.where(calendar_date: calendar_date).size 


    respond_to do |format| 
     if @ticket.save 
     format.html { redirect_to @ticket, notice: 'Job was successfully created.' } 
     format.json { render :show, status: :created, location: @ticket } 
     else 
     @builders = Customer.all 
     format.html { render :new } 
     format.json { render json: @ticket.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

    # .. 

    private 

    # Use callbacks to share common setup or constraints between actions. 
    def set_ticket 
     @ticket = Ticket.find(params[:id]) 
    end 

    # Never trust parameters from the scary internet, only allow the white list through. 
    def ticket_params 

     params.require(:ticket).permit(:customer, 
             :builder, 
             ...) 
    end 
end

試試這個方法

class Ticket < ActiveRecord::Base 
    belongs_to :installer, class_name: "Customer", foreign_key: :builder_id 

    validates :customer, presence: { presence: true, message: 'test' } 
    validates :builder, presence: { presence: true, message: 'test' } 

end
