我正在尝试用Rails圣经做这个教程，我创建了一个新的联系表单，我从书中输入了所有内容：
<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' } %>
以下是我的控制器文件
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
但是我收到语法错误：
SyntaxError in Contact#new

我甚至使用验证器来确保HTML是正确的。我创建了表单以与我放入控制器的新动作相关联。我该如何解决这个错误？
答案 0 :(得分：2)
您缺少一个结束标记
你有
<% form_for :contact, :url => { action => 'create' } do |f|
您缺少%>和操作符号:
<% form_for :contact, :url => { :action => 'create' } do |f| %>
编辑：您可以在sytax错误中看到这一点。如果您在错误中引用的特定行找不到任何错误，您首先应该查看它上面的行。
答案 1 :(得分：0)
您只是错过了%>
将第一行更改为以下内容：
<% form_for :contact, :url => { action => 'create' } do |f| %>
答案 2 :(得分：0)
试试这个： -
<%= form_for :contact, :url => { action => 'create' } do |f| %>
