编辑表单复选框，收音机和trix编辑器没有得到预填充ActiveAdmin

Question

我有一个窗体，有复选框，trix编辑器，单选按钮和文本字段。当我在管理界面中编辑记录时，窗体将显示所有文本字段。我无法看到trix编辑器，复选框和单选按钮。

我知道as: :radio和as: :check_boxes和as: :trix_editor应该工作，但他们没有得到预先填充已保存的值

这是我jobposting.rb文件。

任何帮助将非常感激。

form do |f| 
    f.inputs "New Job Posting" do 
     f.input :title 
     f.input :description, as: :trix_editor 
     f.input :how_to_apply, as: :trix_editor 
     f.input :job_type, as: :radio 
     f.input :city 
     f.input :user_id 
     f.input :categories, as: :check_boxes 

     f.input :publish 


    end 
    f.actions 
    end 

和形式出现这样

它没有显示的字段（说明，如何申请），它应该有TRIX编辑器。对于电台（作业类型）和复选框（分类）字段显示其简单的是和no..where作为这些字段的实际值是这些

解决

ActiveAdmin.register JobPosting do 

# See permitted parameters documentation: 
# https://github.com/activeadmin/activeadmin/blob/master/docs/2-resource-customization.md#setting-up-strong-parameters 
# 
permit_params :title, :description,:how_to_apply, :job_type ,:city,:user_id,{ categories: []}, :publish 
# 
# or 
# 
# permit_params do 
# permitted = [:permitted, :attributes] 
# permitted << :other if params[:action] == 'create' && current_user.admin? 
# permitted 
# end 


form do |f| 
    inputs "New Job Posting" do 

     input :title 
     input :description 
     input :how_to_apply 
     input :job_type, as: :radio, collection: [ 'FullTime', 'Contract', 'PartTime', 'Freelance', 'Intern'] 
     input :city 
     input :user, member_label: :email 
     input :categories, as: :check_boxes, collection: ['Front End','Back End','Others'].map { |e| [e, e,{checked: f.object.categories.include?(e)}] } 

     input :publish 


    end 
    actions 
    end 


end 

Answer 2

这样看来，trix_editor不与activeadmin兼容，所以我不知道，如果你将能够使用，在所有。对于其他人，您需要包括一个集合才能显示，否则它会默认显示为“是/否”框。所以这样的事情：

f.input :categories, as: :check_boxes, collection: f.object.categories 

这应该让主动管理员知道你想使用可用的选项来填充复选框。

编辑：

试试这个：

form do |f| 
    inputs "New Job Posting" do 
     input :title 
     input :description 
     input :how_to_apply 
     input :job_type, as: :radio 
     input :city 
     input :user_id 
     input :categories, as: :check_boxes, collection: f.object.categories 
     input :publish 
    end 
    actions 
    end 

甚至：

form do |f| 
    inputs "New Job Posting" do 
     input :title 
     input :description 
     input :how_to_apply 
     input :job_type, as: :radio 
     input :city 
     input :user_id 
     input :categories, as: :check_boxes, collection: JobPosting.categories 
     input :publish 
    end 
    actions 
    end
