我正在构建一个简单的 wiki 应用程序，并尝试将对象和索引/枚举传递给部分对象，因此当单击按钮时会弹出一个模式，我可以编辑用户。这是我的索引视图代码：
<table class="table table-striped">
<thead>
<th>Name</th>
<th>Email</th>
<th>Role</th>
<th>Action</th>
</thead>
<tbody>
<% @users.each_with_index do |u, index| %>
<tr>
<td><%= u.full_name %></td>
<td><%= u.email %></td>
<td><%= u.role %></td>
<td><%= link_to "Modify", '#edit-user-modal', data: {toggle: "modal", target: "#edit-user-modal#{index}" }, class: 'btn btn-sm btn-success' %></td>
<%= render 'edit_user_modal', u: u, index: index %>
<% end %>
</tr>
</tbody>
</table>
这是我的模态代码：
<div id="edit-user-modal<%= index %>" class="modal fade new-user-modal" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
<div class="modal-dialog modal-sm" 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="mySmallModalLabel">Modify User</h4>
</div>
<div class="modal-body">
<%= form_for(u, url: '/user_admin', method: 'patch') do |f| %>
<div class="form-group">
<%= f.label :full_name, class: 'control-label' %>
<%= f.text_field :full_name, class: "form-control" %>
<%= f.label :email, class: 'control-label' %>
<%= f.text_field :email, class: "form-control" %>
<%= f.label :password, "Enter existing or New Password", class: 'control-label' %>
<%= f.password_field :password, "Enter existing or New Password Confirmation", class: "form-control" %>
<%= f.label :password_confirmation, class: 'control-label' %>
<%= f.password_field :password_confirmation, class: "form-control" %>
<%= f.label :role, class: 'control-label' %>
<%= f.text_field :role, class: "form-control" %>
</div>
<div class="form-group">
<%= f.submit "Create Users", class: "btn btn-primary" %>
</div>
<% end %>
</div>
</div>
</div>
</div>
我以前设置过这样的东西，并且像这样传递当地人没有问题，但在这种特殊情况下，错误会在 wrong number of arguments (given 3, expected 1..2)
我之前使用过相同的策略来部分传递当地人并且没有问题。但由于某种原因，我收到此错误。
注意我使用的是 Rails 5.1 和 Ruby 2.4.0

答案是部分:)
查看下面的行：
<%= f.password_field :password, "Enter existing or New Password Confirmation", class: "form-control" %>第二个参数是标签，似乎是上面一行中的一个简单的复制和粘贴错误。如果您删除该文本，一切都会好起来的。
