لدي مشكلة مع أكتيفادمين باستخدام روبي روبي 1.9.2 ص 290 وروبي على القضبان 3.2.1.
لقد استخدمت صفحة الويكي هذه لإعداد المورد للمشرفين الذي يعمل بشكل مثالي: مورد المشرف الأول الخاص بك:المشرف
بعد ذلك أردت إنشاء المورد لنموذج مشروعي.تبدو عمليات الترحيل لذلك كما يلي:
class CreateProjects < ActiveRecord::Migration
def change
create_table :projects do |t|
t.string :name
t.text :description
t.boolean :isactive
t.timestamps
end
end
end
class AddSlugToProjects < ActiveRecord::Migration
def change
add_column :projects, :slug, :string
add_index :projects, :slug
end
end
نموذج مشروعي:
class Project < ActiveRecord::Base
scope :isactive, :conditions => ["isactive = ?",true]
extend FriendlyId
friendly_id :name, use: [:slugged, :history]
attr_accessible :name, :description, :isactive
end
وهذا هو وحدة التحكم في المشروع:
class ProjectsController < ApplicationController
def index
#
# @projects gets filled in application_controller to be always
# available for the twitter bootstrap navbar
# @projects = Project.isactive.find(:all, :order => 'LOWER(name) asc')
#
end
def show
@project = Project.isactive.find(params[:id])
if request.path != project_path(@project)
redirect_to @project, :status => :moved_permanently
end
end
end
المشرف / المشاريع.رب حاليا'فارغة'
ActiveAdmin.register Project do
end
وبعد كل ذلك ، كل ما أحصل عليه هو الخطأ التالي:

وليس لدي أي فكرة ما هي المشكلة...
المحلول
آه ، لقد وجدت الحل. لا أعرف بالضبط سبب حدوث الخطأ ولكن اضطررت إلى تغيير application_controller.
في application_controller ، قمت بجلب جميع المشاريع إلىprojects:
Genacodicetagpreكان ذلك محيرًا لـ ActiveAdmin.بعد أن غيرت ذلك إلى Genacodicetagpre
وعمل مؤشر project_controller على Genacodicetagpre
كل شيء سار بشكل جيد ؛)
نصائح أخرى
الحل الأسهل هو تخطي عامل التصفية في وحدة تحكم المشرف النشطة المحددة: Genacodicetagpre
المشرف النشط جعل معالجة خاصة من @resource المتغيرات.أين resource يتم تمرير اسم الفئة المقابل إلى طريقة التسجيل.لذلك بالنسبة للرمز:
ActiveAdmin.register Project do
end
اسم المتغير هو
`@project`
يجب ألا نخصص قيمة للمتغير بهذا الاسم.أيضا قد تكون هذه فاريبلز كائن من أكتيفريكورد:: فئة العلاقة.وكيف @ أوليفر كتابة اسم مثل @ بروجيكتس_ال هو خيار جيد.استخدام تخطي قبل التصفية هو حل المشكلة أيضا.
شيء واحد ماكرة تحتاج إلى التحقق.قد لا تحتوي وحدة التحكم في المورد على أي عوامل تصفية.قد لا توجد وحدة تحكم المورد على الإطلاق.ما هو اسم المرشح الذي يجب وضعه في التخطي قبل التصفية?وأين هي هذه المرشحات?يتم استخدام وحدة تحكم التطبيق الافتراضية على أي حال.قد يتم تثبيت المرشح في وحدة تحكم التطبيق الرئيسية.رسالة الخطأ لهذه المشكلة ليست مفيدة على الإطلاق.لذلك تحتاج إلى التحقق من وحدة تحكم التطبيق للمرشحات المثبتة أيضا.
