Question

我不太了解为什么在URL甚至都没有更改的情况下，单击简单的Rails表单上的Submit按钮就会将页面刷新为“您要查找的页面不存在”。提交具有有效数据的表单似乎也不会在任何数据库中创建这样的条目。任何方向将不胜感激。

下面是/app/views/helps/new.html.erb

html, body {
  margin: 0;
  height: 100%;
  overflow: hidden; 
} 
.container {
   margin-top: 60px;
} 

</style>

<% if logged_in? %>
  <div class= "container">
    <% provide(:title, "Submit Inquiry") %>
    <br><h2><center>Submit Inquiry</center></h2>
    <p></p>
    <div class="row">
      <div class="col-md-6 col-md-offset-3">
      <%= form_for(:helps, url: new_help_path) do |f| %>

          <%= f.label :email %>
          <%= f.email_field :email, class: 'form-control' %>
          <%= f.label :text %>
          <%= f.text_area :text, class: 'form-control' %>
          <p></p>
          <%= f.submit "Submit", class: "btn btn-primary" %>
        <% end %>
      </div>
    </div>
  </div>
<% else %>
  <div class="alert alert-danger"><br>
    <br><%= link_to "Please log in to continue", root_path %>
  </div>
<%end%>

下面是helps_controller

class HelpsController < ApplicationController
  before_action :get_user,         only: [:edit, :update]
  before_action :valid_user,       only: [:edit, :update]

  def new
  end

  def create
      @user= User.find(params[:id])
      if current_user?(@user)
        flash[:success] = "Inquiry submitted."
        redirect_to new_help_path
    else
      flash.now[:danger] = "Only users can submit inquiries."
      redirect_to root_url
    end
  end


  private

    def get_user
      @user = User.find_by(email: params[:email])
    end

    # Confirms a valid user.
    def valid_user
      unless (@user && @user.activated? &&
              @user.authenticated?(:reset, params[:id]))
        redirect_to root_url
      end
    end

end

以下是我的路线。rb

Rails.application.routes.draw do

  root 'sessions#new'
  get '/home', to: 'static_pages#home'
  get '/add/parts', to: 'static_pages#part'
  get '/add/projects', to: 'static_pages#project'
  get '/add/vendors', to: 'static_pages#vendor'
  get '/signup', to: 'users#new'
  post '/signup', to: 'users#create'
  get '/login', to: 'sessions#new'
  post '/login', to: 'sessions#create'


  delete '/logout', to: 'sessions#destroy'

  resources :users
  resources :account_activations, only: [:edit]
  #users can generate new passwords (reset), and change them 
  resources :password_resets, only: [:new, :create, :edit, :update]
  resources :helps,  only: [:new, :create]
end

以下是我_header.html.erb

中的相关代码

<body>
  <header>
    <ul class= "nav">
      <li><a class="active" href="/home">Home</a></li>
      <% if logged_in? %>
        <li><%= link_to "Profile", edit_user_path(current_user.id) %></li>
      <%end%>
      <li id= "options">
        <a href="#">Add</a>
        <ul class= "subnav">
            <li><%= link_to "Part", add_parts_path%></li>
            <li><%= link_to "Project", add_projects_path%></li>
            <li><%= link_to "Vendor", add_vendors_path%></li>
        </ul>
      </li>
      <li><%= link_to "Help", new_help_path, method: :create %></li>
      <li><%= link_to "Log Out", logout_path, method: :delete %></li>
      <li id= "search">
        <form action= "" method= "get">
            <input type="text" name="search_text" id= "search_text" placeholder="Search Page"/>
            <button type="submit"><i class="fa fa-search"></i></button>
        </form>
      </li>
    </ul>
  </header>
  </body>

下面是我的index.html.erb

<p id="notice"><%= notice %></p>

<h1>Posts</h1>

<table>
  <thead>
    <tr>
      <th>Title</th>
      <th>Body</th>
      <th colspan="3"></th>
    </tr>
  </thead>

  <tbody>
    <% @posts.each do |post| %>
      <tr>
        <td><%= post.title %></td>
        <td><%= post.body %></td>
        <td><%= link_to 'Show', post %></td>
        <td><%= link_to 'Edit', edit_post_path(post) %></td>
        <td><%= link_to 'Destroy', post, method: :delete, data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>
    <% @helps.each do |help| %>
      <%= help.email %>
    <% end %>
  </tbody>
</table>

<br>

<%= link_to 'New Post', new_post_path %>

Answer 1

您似乎在create方法中找到了一个用户，然后将其重定向到new_helps_path。
def新 @help = Help.new 结束 def创建 @ user = User.find（params [：id]）＃@help（或任何命名的模型）= Help.new 如果current_user？（@ user） @ help.create（电子邮件：params [：email]） flash [：success] =“已提交查询。” redirect_to new_help_path 其他 flash.now [：danger] =“只有用户可以提交查询。 redirect_to root_url 结束结束

在<%= form_for(@help, url: RAKE ROUTES AND PICK THE PATH WITH ACTION CREATE) do |f| %>中，路径应该是您发布表单的位置，在这种情况下，它是带有POST的create方法

仅：帮助：[：创建，索引，显示，新建]

def index
@helps = Help.all
end

然后在index.html.erb

<% @helps.each do |help| %>
  <%= help.email %>
<% end %>

提交Rails表单会导致页面不存在
