Question

我一直在使用link_to删除所有索引文件中的路由时遇到麻烦，无法弄明白。我最近将所有内容命名为：backend。

网址的结构类似于此后端/ membercontacts / 1 / memberlistings /

就像form_for一样，我试图给它一个网址或正确的路径无济于事。这是在命名空间之前所做的工作。

<%= link_to 'Delete',  [memberlisting.membercontact, memberlisting], method: :delete, data: { confirm: 'Are you sure? This will also remove this listing from the online directories.' }, :class => "btn btn-danger btn-sm" %>

补充视图：views / backend / memberlistings / index.html.erb

<div class="card">
    <div class="card-block">
        <h4 class="card-title">Member Listing Index</h4>
        <table class="table table-hover table-striped">
            <thead>
                <tr>
                    <th>Full Name</th>
                    <th>Company Name</th>
                    <th>City</th>
                    <th>Province</th>
                    <th>Phone Number</th>
                    <th>Email</th>
                    <th colspan="3"></th>
                </tr>
            </thead>
            <tbody>
                <% @memberlistings.each do |memberlisting| %>
                    <tr>
                        <td><%= memberlisting.mlcontactname %></td>
                        <td><%= memberlisting.mlcompanyname %></td>
                        <td><%= memberlisting.mlcity %></td>
                        <td><%= memberlisting.mlprovince %></td>
                        <td><%= memberlisting.mlphone %></td>
                        <td><%= memberlisting.mlemail %></td>
                        <td>
                            <div class="btn-group" role="group" aria-label="Member Listings Group">
                <%= link_to 'Details', backend_membercontact_memberlisting_path(memberlisting.membercontact, memberlisting), :class => "btn btn-primary btn-sm" %>
                <%= link_to 'Edit', edit_backend_membercontact_memberlisting_path(memberlisting.membercontact, memberlisting), :class => "btn btn-primary btn-sm" %>
                <%= link_to 'Delete',  [memberlisting.membercontact, memberlisting], method: :delete, data: { confirm: 'Are you sure? This will also remove this listing from the online directories.' }, :class => "btn btn-danger btn-sm" %>
                            </div>
                        </td>
                    </tr>
                <% end %>
            </tbody>
        </table>
    <%= link_to 'New Member Listing', new_backend_membercontact_memberlisting_path, :class => "btn btn-primary btn-sm" %>
    </div>
</div>

在我看来，你似乎错过了那里的backend_membercontact_memberlisting_path ...试试这个：

<%= link_to 'Delete',  backend_membercontact_memberlisting_path(memberlisting.membercontact, memberlisting), method: :delete, data: { confirm: 'Are you sure? This will also remove this listing from the online directories.' }, :class => "btn btn-danger btn-sm" %>
