如何在使用Ruby on Rails在數據庫中搜索值的ajax表單上添加jquery驗證？

Question

因此，我最近實現了電話/ SIM卡檢查器。 第一個表單輸入要求用戶輸入他們的電話號碼。 如果數據庫中存在電話號碼，則呈現“找到電話號碼”消息，否則將電話號碼表單替換為sim號碼表單。 同樣，如果數據庫中存在SIM卡號，則顯示“找到SIM卡號”消息，否則，顯示“ SIM卡未找到”消息。

有誰能向我展示一個示例，說明如何在用戶單擊提交時觸發checkphone / checksim方法之前在用戶輸入上使用jquery驗證？ 我的手機型號（phone.rb）中已設置驗證

下面的代碼：app / controllers / phones_controller.rb

class PhonesController < ApplicationController
  def checkphone
    @phone_number = Phone.where(phone_number: params[:phone][:phone_number])
    respond_to do |format|
      if @phone_number.exists?
        format.js {render 'phone-found'}
      elsif @phone_number.blank?
        format.js {render 'phone-not-found'}
      else
        format.js {render 'errors'}
      end
    end
  end

  def checksim
    @sim_number = Phone.where('sim_number = ?', params[:sim][:sim_number])
    respond_to do |format|
      if @sim_number.exists?
        format.js {render 'sim-found'}
      elsif @sim_number.blank?
        format.js {render 'sim-not-found'}
      else
        format.js {render 'errors'}
      end
    end
  end

  private

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

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

應用程序/模型/ phone.rb

class Phone < ActiveRecord::Base
  validates :phone_number, length: {minimum: 11, maximum: 11}, allow_blank: false
  validates :sim_number, length: {minimum: 12, maximum: 12}, allow_blank: false
end

應用程序/視圖/手機/ index.html.erb

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

應用程序/視圖/手機/電話found.js.erb

$('#phone-number-found').html('Phone Number Found!');
$('#phone-number-not-found').html('');
$('#error').html('');
$('#phone-number-form').hide();

應用程序/視圖/電話/手機 - 不found.js.erb

$('#phone-number-found').append("<%= j render(partial: 'sim') %>")
$('#phone-number-not-found').html('Phone Number Not Found!');
$('#error').html('');
$('#phone-number-form').hide();

應用程序/視圖/手機/ _sim.html.erb

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

應用程序/視圖/手機/ SIM-found.js.erb

$('#phone-number-found').html('Sim Found')
$('#phone-number-not-found').html('');
$('#phone-number-error').html('');

應用程序/視圖/手機/ SIM - 不found.js.erb

$('#phone-number-found').html('');
$('#phone-number-not-found').html('Sim Number Not Found!');
$('#error').html('');

應用程序/視圖/手機/ errors.js.erb

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

配置/ routes.rb中

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

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

如果有人可以向我展示如何在checkphone和checksim方法觸發之前根據我的模型驗證規則應用jquery驗證，將不勝感激。 謝謝！

Answer 1

添加minlength，maxlength和required應該可以解決問題。 然后，sim局部將如下所示：

應用程序/視圖/手機/ _sim.html.erb

<div id="sim-number-found"></div>
<div id="sim-number-not-found"></div>
<div id="error"></div>
<%= form_for :sim, :url => url_for(:action => 'checksim', :controller => 'phones'), remote: true, html: { id: 'sim-number-form'}  do |f| %>
  <%= f.label "Sim Number:" %>
  <%= f.number_field :sim_number, minlength: 12, maxlength: 12, required: true %>
  <%= submit_tag("Check") %>
<% end %>

用戶gem'client_side_validations'也會將服務器端驗證也用於客戶端。
