ruby-on-rails - 视图文件中的语法错误

Question

我正在尝试从 Rails 圣经中完成本教程，我创建了一个新的联系表格，并输入了书中的所有内容：

    <h1>Create New Contact</h1>
<% form_for :contact, :url => { action => 'create' } do |f|
  <p><label for="contact_first_name">First Name:</label>
  <%= f.text_field 'contact', 'first_name' %></p>

  <p><label for="contact_last_name">Last Name:</label>
  <%= f.text_field 'contact', 'last_name' %></p>

  <p><label for="contact_address">Address:</label>
  <%= f.text_field 'contact', 'address' %></p>

  <p><label for="contact_city">City:</label>
  <%= f.text_field 'contact', 'City' %></p>

  <p><label for="contact_state">State:</label>
  <%= f.text_field 'contact', 'state' %></p>

  <p><label for="contact_country">Country:</label>
  <%= f.text_field 'contact', 'country' %></p>

  <p><label for="contact_phone">Phone:</label>
  <%= f.text_field 'contact', 'phone' %></p>

  <p><label for="contact_email">Email:</label>
  <%= f.text_field 'contact', 'email' %></p>

  <%= f.submit "Create" %>
<% end %>  

<p><%= link_to 'Back', { :action => 'index' } %>

下面是我的控制器文件

    class ContactController < ApplicationController

  def index
    @contacts = Contact.find(:all)
  end

  def show
  end

  def new
    @contact = Contact.new
  end
  def create
  end

  def update
  end
end

但我得到一个语法错误：

SyntaxError in Contact#new

我什至使用验证器来确保 HTML 是正确的。我创建了与我放入控制器中的新操作相关联的表单。我该如何解决这个错误？

您缺少一个结束 rails 标记

你有

<% form_for :contact, :url => { action => 'create' } do |f|

您缺少%>和动作符号:

<% form_for :contact, :url => { :action => 'create' } do |f| %>

编辑：您可以在语法错误中看到这一点。如果您找不到错误中引用的特定行有任何问题，您首先想到的应该是查看它上面的行。

你只是缺少一个%>

将第一行更改为以下内容：

<% form_for :contact, :url => { action => 'create' } do |f| %>

试试这个： -

<%= form_for :contact, :url => { action => 'create' } do |f| %>
