尝试使用模式进行用户创建时出现意外的 tIVAR
unexpected tIVAR while attempting to use modal for user create
我正在构建用于创建用户的模式（只有管理员可以创建用户。）我收到了意外的 tVAR 错误。我已经多次检查我的代码，但似乎无法找出我哪里出错了。
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，如果不成功则重定向到应用程序 root_path（只构建了显示页面，我将在稍后构建索引。（我觉得这可能是我出错的地方。）
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
我的 routes.rb 用于自定义路径 - 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 -->
模态框已放在 application.html.erb 页面上——这也可能是问题所在？但是，我不确定该把它放在哪里..
最后，我的模式 link（在导航栏中找到）：
<%= link_to "Create New User", "#userCreate", "data-toggle" => "modal" %>
如有任何帮助，我们将不胜感激！如果您需要任何进一步的信息，请告诉我。

您缺少右括号：
<%= form_for(@user, :url => admins_create_user_path do |f| %>
应该是：
<%= form_for(@user, :url => admins_create_user_path) do |f| %>
您的 form_for(@user, :url => admins_create_user_path 没有右括号。
