呈现不在控制器中的第二种方法

Question

我正在实现一个电话和SIM卡检查器，它由用户首先输入一个电话号码组成。如果输入的电话号码在数据库中，则此表单将消失，并显示另一个表单以检查用户SIM卡号码是否在数据库中。 我目前遇到的问题是第一种方法（def phonechecker）呈现phone-found.js.erb，phone-not-found.js.erb和error.js.erb没问题。但是，我得到一个模板错误：

Missing template phones/phone-not-found, application/phone-not-found with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :axlsx, :haml]}. 

，当我尝试呈现相同的模板/ S又在已sumbitted他们SIM_NUMBER，运行simchecker方法时会出现此错误。

下面的代码：

应用程序/控制器/ phones_controller.rb

class PhonesController < ApplicationController 
    protect_from_forgery with: :null_session 
    def checkphone 
    @phone_number = Phone.where('phone_number = ?', params[:phone][:phone_number]) 
    if @phone_number.exists? 
     render 'phone-found' 

    elsif @phone_number.blank? 
     render 'phone-not-found' 

    else 
     render 'errors' 
    end 
    end 

    def checksim 
    @sim_number = Phone.where('sim_number = ?', params[:sim][:sim_number]) 
    if @sim_number.exists? 
     render 'phone-found' 

    elsif @sim_number.blank? 
     render 'phone-not-found' 

    else 
     render 'errors' 
    end 
    end 

    private 

    def phone_params 
    params.require(:phone).permit(
     :phone_number 
    ) 
    end 

    def sim_params 
    params.require(:sim).permit(
     :sim_number 
    ) 
    end 
end 

应用程序/视图/手机/电话found.js.erb

$('#phone-number-found').append("<%= j render(partial: 'sim') %>") 
$('#phone-number-not-found').html(''); 
$('#phone-number-error').html(''); 
$('#phone_phone_number').hide(); 

应用程序/视图/手机/phone-not-found.js.erb

$('#phone-number-found').html(''); 
$('#phone-number-not-found').html('Working!'); 
$('#phone-number-error').html(''); 

应用程序/视图/手机/ error.js.erb

$('#phone-number-found').html(''); 
$('#phone-number-not-found').html(''); 
$('#phone-number-error').html('Working!'); 

应用程序/视图/手机/ _sim.html.erb

<%= form_for :sim, :url => url_for(:action => 'checksim', :controller => 'phones'), remote: true, :authenticity_token => false, html: { id: 'sim-number-form'} do |f| %> 
    <div id="phone-number-found"></div> 
    <div id="phone-number-not-found"></div> 
    <div id="phone-number-error"></div> 
    <%= f.text_field :sim_number %> 
    <%= submit_tag("Check") %> 
<% end %> 

应用程序/视图/手机/ index.html.erb

<%= form_for :phone, :url => url_for(:action => 'checkphone', :controller => 'phones'), remote: true, :authenticity_token => false, html: { id: 'phone-number-form'} do |f| %> 
    <div id="phone-number-found"></div> 
    <div id="phone-number-not-found"></div> 
    <div id="phone-number-error"></div> 
    <%= f.text_field :phone_number %> 
    <%= submit_tag("Check") %> 
<% end %> 

配置/ routes.rb中

post "/checkphone" => "phones#checkphone" 
    post "/checksim" => "phones#checksim" 

    resources :phones, path: '4g-promo' 

如果有人能解决我的问题，将不胜感激。谢谢！

在错误中，您可以看到它正在寻找html :formats=>[:html]或其中一个变体：:erb, :builder, :raw, :ruby, :coffee, :axlsx, :haml。但你想要它寻找.js.erb。你需要像控制器方法中添加的respond_to方法：

def checksim 
    @sim_number = Phone.where('sim_number = ?', params[:sim][:sim_number]) 

    respond_to do |format| 
    if @sim_number.exists? 
     format.js {render 'phone-found'} 
    elsif @sim_number.blank? 
     format.js {render 'phone-not-found'} 
    else 
     format.js {render 'errors'} 
    end 
    end 
end
