在设计页面外更新用户信息

Question

我想为用户添加从 /settings 页面而不是 /users/edit 页面编辑他的电子邮件/密码/图像的选项。所以我把代码复制到设置页面

    <%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put }) do |f| %>
  <%= devise_error_messages! %>
  <div class="field">
    <%= f.label :email %><br />
    <%= f.email_field :email, autofocus: true %>
  </div>

  <% if devise_mapping.confirmable? && resource.pending_reconfirmation? %>
    <div>Currently waiting confirmation for: <%= resource.unconfirmed_email %></div>
  <% end %>

  <div class="form-group">
    <%= f.label :image %>
    <%= f.file_field :image, class: 'form-control'%>
  </div>

  <div class="form-group">
    <%= f.label :cover %>
    <%= f.file_field :cover, class: 'form-control'%>
  </div>

  <div class="field">
    <%= f.label :password %> <i>(leave blank if you don't want to change it)</i><br />
    <%= f.password_field :password, autocomplete: "off" %>
  </div>

  <div class="field">
    <%= f.label :password_confirmation %><br />
    <%= f.password_field :password_confirmation, autocomplete: "off" %>
  </div>

  <div class="field">
    <%= f.label :current_password %> <i>(we need your current password to confirm your changes)</i><br />
    <%= f.password_field :current_password, autocomplete: "off" %>
  </div>

  <div class="actions">
    <%= f.submit "Update" %>
  </div>
<% end %>

<h3>Cancel my account</h3>

<p>Unhappy? <%= button_to "Cancel my account", registration_path(resource_name), data: { confirm: "Are you sure?" }, method: :delete %></p>

<%= link_to "Back", :back %>

但它返回了这个

undefined local variable or method `resource' for #<#<Class:0x007f60245ab9b0>:0x007f6026f58358>

我应该向控制器添加什么？

Answer 1

当您想要执行任何自定义操作时，首先创建一个action in a controller，然后为它创建一个route，然后是view file。

资源对象仅在设计路线中可用。

所以，首先在任何控制器中添加一个名为 settings 的方法，例如：userscontroller。

class UsersController < ApplicationController
    def settings
        @user = current_user
    end
end

然后在 routes.rb 中，添加一个指向这个动作的路由，路由命名为'/settings'

get '/settings' => 'users#settings', as: :settings

现在，在 app/views/users/settings.html.erb

<%= form_for(@user, url: registration_path(@user), html: { method: :put }) do |f| %>
      <%= devise_error_messages! %>
      <div class="field">
        <%= f.label :email %><br />
        <%= f.email_field :email, autofocus: true %>
      </div>

      <% if devise_mapping.confirmable? && resource.pending_reconfirmation? %>
        <div>Currently waiting confirmation for: <%= resource.unconfirmed_email %></div>
      <% end %>

      <div class="form-group">
        <%= f.label :image %>
        <%= f.file_field :image, class: 'form-control'%>
      </div>

      <div class="form-group">
        <%= f.label :cover %>
        <%= f.file_field :cover, class: 'form-control'%>
      </div>

      <div class="field">
        <%= f.label :password %> <i>(leave blank if you don't want to change it)</i><br />
        <%= f.password_field :password, autocomplete: "off" %>
      </div>

      <div class="field">
        <%= f.label :password_confirmation %><br />
        <%= f.password_field :password_confirmation, autocomplete: "off" %>
      </div>

      <div class="field">
        <%= f.label :current_password %> <i>(we need your current password to confirm your changes)</i><br />
        <%= f.password_field :current_password, autocomplete: "off" %>
      </div>

      <div class="actions">
        <%= f.submit "Update" %>
      </div>
    <% end %>

<h3>Cancel my account</h3>

<p>Unhappy? <%= button_to "Cancel my account", registration_path(resource_name), data: { confirm: "Are you sure?" }, method: :delete %></p>

<%= link_to "Back", :back %>

所以，在用户的显示页面中添加一个指向设置页面的链接，

<%= link_to 'Edit', settings_path(user) %>
