【问题描述】：
我正在构建一个用于创建用户的模式（只有管理员可以创建用户。）我收到了一个意外的 tVAR 错误。我现在已经多次查看我的代码，但似乎无法找到我出错的地方。
错误是（rails 服务器输出：）
SyntaxError - syntax error, unexpected tIVAR, expecting ')'
@output_buffer.safe_append=' <...
^:
我创建了第二个“AdminsController” - 如下所列。 （我的目标是在成功保存时重定向到 user_show_page 或如果不成功则重定向到应用程序 root_path （仅构建了显示页面，我将在以后构建索引。（我感觉这可能是我错了。）
class AdminsController < ApplicationController
before_action :authenticate_user!
def new_user
authorize! :manage, User
@user = User.new
end
def create_user
@user = User.new(permitted_params.user)
authorize! :manage, User
if @user.save
format.html { redirect_to root_path, notice: 'User has been successfully created.' }
else
format.html { redirect_to root_path, notice: 'There was a problem creating this user, please try again.' }
end
end
end
自定义路径的我的 routes.rb - 下面
as :user do
get "admins/new_user" => "admins#new_user", as: :admins_new_user
post "admins/create_user/:id" => "admins#create_user", as: :admins_create_user
end
我的模态形式 - 如下：
<!-- Start - Modles -->
<!-- Start - New User Creation -->
<%= form_for(@user, :url => admins_create_user_path do |f| %>
<div class="modal fade" id="userCreate" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Create New System User</h4>
</div>
<div class="modal-body">
Form Fields HERE....
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<%= f.submit "Create User", :class => 'btn btn-primary' %>
</div>
</div>
</div>
</div>
<% end %>
<!-- End - New User Creation -->
<!-- End - Modles -->
模态框已放置在 application.html.erb 页面上——这也可能是问题所在？不过我不知道还能把它放在哪里..
最后，我的模态链接（在导航栏中找到）：
<%= link_to "Create New User", "#userCreate", "data-toggle" => "modal" %>
任何帮助将不胜感激！如果您需要任何进一步的信息，请告诉我。

【问题讨论】：
-
你能添加回溯吗？
-
肯定是有问题的更新
-
您的
form_for(@user, :url => admins_create_user_path没有右括号。 -
尼克，添加为答案并错误地奖励最佳......我的愚蠢错误。
-
不介意我这样做:)
