Rails 5:陷入编辑操作,更新无效

我已经遇到了一些简单的事情,我已经尝试了很多不能工作的事情。这就是我所拥有的。 在我的应用中,current_user需要更新属于current_user公司的用户的角色。我可以进入编辑操作,在适当的位置显示特定用户角色,但我无法执行更新操作 - 它始终保留在编辑操作

这就是我在 /models/role.rb 中所拥有的:

class Role < ApplicationRecord
belongs_to :user, optional: true, inverse_of: :roles
accepts_nested_attributes_for :user

enum general: { seller: 1, buyer: 2, seller_buyer: 3}, _suffix: true
enum dashboard: { denied: 0, viewer: 1, editer: 2, creater: 3, deleter: 4}, _suffix: true
# other columns for roles follow #

/models/user.rb 如下所示:

#User has roles
  has_many :roles
  has_many :company_user_roles, through: :companies, source: :user_roles
  accepts_nested_attributes_for :roles, reject_if: proc { |attributes| attributes[:name].blank? }

# User has many companies
  has_many :accounts, dependent: :destroy
  has_many :companies, through: :accounts

/controllers/common/roles_controller.rb 中我有:

class Common::RolesController < ApplicationController

def edit
@role = Role.find(params[:id])
end

def update
@role = Role.find(params[:id])
if @role.update_attributes(role_params)
  flash[:success] = "Role updated!"
  redirect_to dashboard_path
else
  render 'edit'
end

private

def role_params #at the end ID of user to whom belongs role is stored
  params.require(:role).permit(:general, :dashboard, //..other role table columns..// , :user_id)
end

/views/common/roles/edit.html.erb 中我有:

<%= form_for ([:common, @role]) do |f| %>
  <%= f.select :general, Role.generals.map { |key, value| [key.humanize, key] } %>
  <%= f.select :dashboard, Role.dashboards.map { |key, value| [key.humanize, key] } %>
  <%= f.submit "Save changes" %>
<% end %>

当我打开 / common / roles / 1 / edit 时,我看到了:

Started GET "/common/roles/1/edit" for 194.8.16.19 at 2016-10-17 13:08:17 +0000
Processing by Common::RolesController#edit as HTML
Parameters: {"id"=>"1"}
User Load (0.2ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = ? LIMIT ?  [["id", 1], ["LIMIT", 1]]
Role Load (0.5ms)  SELECT  "roles".* FROM "roles" WHERE "roles"."id" = ? LIMIT ?  [["id", 1], ["LIMIT", 1]]

当我按下&#34;保存更改&#34;按钮,我看到了:

Started GET "/common/roles/1/edit?utf8=%E2%9C%93&_method=patch&authenticity_token=QoCCvXkM2%2B77ZyO0npTBKv1PKTQdkFjkLLbIgmdSXN8uli1ElLBfwHD6GXVTA%2Fa65cQPVPCqJNSkF0d8l5SSgw%3D%3D&general=seller_buyer&dashboard=editer&rights=editer&commit=Save+changes" for 194.8.16.19 at 2016-10-17 13:10:54 +0000
Processing by Common::RolesController#edit as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"QoCCvXkM2+77ZyO0npTBKv1PKTQdkFjkLLbIgmdSXN8uli1ElLBfwHD6GXVTA/a65cQPVPCqJNSkF0d8l5SSgw==", "general"=>"seller_buyer", "dashboard"=>"editer", "rights"=>"editer", "commit"=>"Save changes", "id"=>"1"}
User Load (0.5ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = ? LIMIT ?  [["id", 1], ["LIMIT", 1]]
Role Load (0.4ms)  SELECT  "roles".* FROM "roles" WHERE "roles"."id" = ? LIMIT ?  [["id", 1], ["LIMIT", 1]]

或者像这样:

--- !ruby/object:ActionController::Parameters
parameters: !ruby/hash:ActiveSupport::HashWithIndifferentAccess
  utf8: "✓"
  _method: patch
  authenticity_token: QoCCvXkM2+77ZyO0npTBKv1PKTQdkFjkLLbIgmdSXN8uli1ElLBfwHD6GXVTA/a65cQPVPCqJNSkF0d8l5SSgw==
  general: seller_buyer
  dashboard: editer
  rights: editer
  commit: Save changes
  controller: common/roles
  action: edit
  id: '1'
permitted: false

看起来没有传递&#34;角色&#34; =&gt; {... 并且在令牌之后它显示我尝试更新的参数。据我所知,这可能是为什么更新没有发生。

role routes.rb 如下所示:

 namespace :common do
   resources :companies
   resources :roles
 end

角色的索引和编辑操作起作用,所有操作(包括更新)都适用于公司。

我对这个错误有点绝望,因为我尝试了很多东西,但是没有任何作用。 如何解决此问题以使更新操作正常工作?感谢您提供潜在错误的任何提示。

更新 我可以在控制台中手动更新角色,没有问题 - 按ID查找角色并更新任何列。表单上仍然没有运气 - 在f.submit之后保留在编辑操作中。

似乎所有路线都很好:

                     common_roles GET    /common/roles(.:format)                          common/roles#index
                                  POST   /common/roles(.:format)                          common/roles#create
                  new_common_role GET    /common/roles/new(.:format)                      common/roles#new
                 edit_common_role GET    /common/roles/:id/edit(.:format)                 common/roles#edit
                      common_role GET    /common/roles/:id(.:format)                      common/roles#show
                                  PATCH  /common/roles/:id(.:format)                      common/roles#update
                                  PUT    /common/roles/:id(.:format)                      common/roles#update
                                  DELETE /common/roles/:id(.:format)                      common/roles#destroy

到目前为止还不知道为什么错误仍在发生......据我所知,这不是因为错误的路线。

好的,我已经想通了,为什么编辑动作卡住了 - 因为我认为form_for<form class>标记之前或之后无关紧要。似乎我必须把它放在<form class>标签之前。所以现在没有我在screent上发现主要错误:param is missing or the value is empty: role 任何想法为什么?

更新4

好的,现在我已经找到了主要问题。基本上Enums根本没有更新。由于我的表单仅由枚举组成,因此不会传递也不会更新。现在我必须找出,我必须如何正确保存/更新枚举。欢迎任何提示!

form_for ([:common, @role], :html => { method: 'POST' })应该有效
