在为我的工作人员活动记录设置表单时遇到一些问题.我有一个用户 has_many 工人关系，并且有工人的嵌套路由.我的表单代码在视图的 workers 目录中的 new.html.erb 文件中.
<h1>设置一个工人</h1><p>输入以下信息，将您的工作人员连接到我们的服务.</p><div class="row"><div class="span6 offset3"><%= form_for(@worker) 做 |w|％＞<%=w.label :ip_address, "worker的IP地址" %><%=w.text_field :ip_address %><%= w.submit "Create Worker", class: "btn btn-medium btn-primary" %><%结束%>在我的工人控制器中，我有这个
class WorkersController 但是当我尝试加载该页面时出现此错误
Workers 中的 NoMethodError#new它指向这条线
<%= form_for(@worker) do |w|％＞感谢您的帮助.
解决方案 <%= form_for[@user, @worker] do |w|％＞<%=w.label :ip_address, "worker的IP地址" %><%=w.text_field :ip_address %><%= w.submit "Create Worker", class: "btn btn-medium btn-primary" %><%结束%>定义新@worker = Worker.new@user = User.find(params[:id]) 或其他加载用户的方式结尾Having some issues setting up a form for my worker active record. I have a user has_many workers relationship and had nested routes for the workers. my form code is below in my new.html.erb file in the workers directory of the view.
<h1>Setup a Worker</h1>
<p>
Enter in the information below to connect your worker to our service.
</p>
<div class="row">
<div class="span6 offset3">
<%= form_for(@worker) do |w| %>
<%= w.label :name %>
<%= w.text_field :name %>
<%=w.label :ip_address, "Ip address of the worker" %>
<%=w.text_field :ip_address %>
<%= w.submit "Create Worker", class: "btn btn-medium btn-primary" %>
<% end %>
</div>
</div>
In my workers controller I have this
class WorkersController < ApplicationController
def new
@worker = Worker.new
end
def show
end
end
But when I try and load that Page I get this error
NoMethodError in Workers#new
and it points to this line
<%= form_for(@worker) do |w| %>
Thanks for the help.
解决方案 <%= form_for[@user, @worker] do |w| %>
<%= w.label :name %>
<%= w.text_field :name %>
<%=w.label :ip_address, "Ip address of the worker" %>
<%=w.text_field :ip_address %>
<%= w.submit "Create Worker", class: "btn btn-medium btn-primary" %>
<% end %>
def new
@worker = Worker.new
@user = User.find(params[:id]) or some other way to load the user
end
