Question

我正在构建一个RoR搜索表单。（代码提取看起来很长但非常简单。）

这是内容 app / views / layouts / application.html.erb 文件

<!DOCTYPE html>
<html>
<head>
  <title><%= controller.action_name %></title>
  <%= stylesheet_link_tag    "application", media: "all", "data-turbolinks-track" => true %>
  <%= javascript_include_tag "application", "data-turbolinks-track" => true %>
  <%= csrf_meta_tags %>
</head>
<body>
        <span style="text-align: right">
                <% form_tag "/client_workouts/find" do %>
                        <%= text_field_tag :search_string %>
                        <%= submit_tag "Search" %>
                <% end %>
        </span>

        <p style="color: green"><%= flash[:notice] %></p>

        <%= yield %>

</body>
</html>

这是 app / views / client_workouts / index.html.erb 文件的内容

<h1>Listing client_workouts</h1>

<table>
  <thead>
    <tr>
      <th>Client name</th>
      <th>Trainer</th>
      <th>Duration mins</th>
      <th>Date of workout</th>
      <th>Paid amount</th>
      <th></th>
      <th></th>
      <th></th>
    </tr>
  </thead>

  <tbody>
    <% @client_workouts.each do |client_workout| %>
      <tr>
        <td><%= client_workout.client_name %></td>
        <td><%= client_workout.trainer %></td>
        <td><%= client_workout.duration_mins %></td>
        <td><%= client_workout.date_of_workout %></td>
        <td><%= client_workout.paid_amount %></td>
        <td><%= link_to 'Show', client_workout %></td>
        <td><%= link_to 'Edit', edit_client_workout_path(client_workout) %></td>
        <td><%= link_to 'Destroy', client_workout, method: :delete, data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>
  </tbody>
</table>

<br>

<%= link_to 'New Client workout', new_client_workout_path %>

这是浏览器页面的输出http://rubyonrails/client_workouts：

查看正文标记下方的范围标记，没有搜索表单。

你知道我在这里缺少什么吗？

Answer 1

您需要<%= form_tag ... %>而不是<% form_tag %>。 =是告诉rails输出表单的内容。

RoR 4 - 搜索表单未显示
