Question

我想在数据库中为用户的帖子创建一个条目，而无需重新加载页面。但在触摸时没有找到路线。

let_controller.rb

class LetController < ApplicationController
  respond_to :html, :js

  def index
  end

  def contacts
    @contacts = Question.new
  end


  def language
    session[:language] = params[:language][0..1]
    set_language
    redirect_to root_path
  end

  def new
    @contacts = Question.new
  end

  def create
    @contacts = Question.new(question_params)
    @contacts.request = request
  end

  private

  def question_params

    params.require(:questions).permit(:name, :e_mail, :phone, :text_q )

  end
end

contacts.html.erb

<div id="main-block">

    <%= render 'contact_form' %>
</div>

_contact_form.html.erb

 <ul class="errors"></ul>
   <%= form_for @contacts , :remote => true  do |f| %>
        <%= f.text_field :name , placeholder: "Имя" %> <br>
        <%= f.text_field :e_mail, placeholder: "e-mail" %><br>
        <%= f.text_field :phone, placeholder: "Телефон" %><br>
        <%= f.text_area :text_q, placeholder: "Сообщение" %><br>
     <%= f.submit "Задать вопрос", class: "btn btn-primary"%>
    <% end %>

save.js.erb

$("ul.errors").html("")
<% if @contacts.errors.any? %>
<% @contacts.errors.full_messages.each do |message| %>
$("ul.errors").append($("<li />").html("<%= message.html_safe %>"))
<% end %>
<% else %>
$("#main-block").empty()
$("#main-block").html("Сообщение отправлено!")
<% end %>

create.js.erb

<%= render 'save' %>

new.js.erb

$("#main-block").html("<%= escape_javascript(render 'contact_form') %>")

的routes.rb

 resources :let

  root 'let#index'
  match '/index', to: 'let#index', via: 'get'
  match '/contacts', to: 'let#contacts', via: 'get'
  post '/let/contacts', as: 'contacts'

终端加载页面

Answer 1

您可以将路线重构为

resources :let do
  collection do
    get 'contacts', to 'let#contacts'
    post 'contacts', to 'let#create', as: :create_contacts
  end
end

root 'let#index'

并更改表单中的网址

<%= form_for @contacts, url: { action: :create }, remote: true  do |f| %>

无需重新加载页面即可进入数据库 - 没有路由匹配[POST]＆＃34; / contacts＆＃34;
