Question

我有一个包含复选框，trix编辑器，单选按钮和文本字段的表单。当我在管理界面中编辑记录时，将显示包含所有文本字段的表单。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以及as: :trix_editor应该有效，但是他们没有预先填充已保存的值

这是我的jobposting.rb文件。

任何帮助都将非常感激。

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

，表单如下所示

它没有显示应该有trix编辑器的字段（描述，如何应用）。对于广播（作业类型）和复选框（类别）字段，其显示简单的是和否..其中这些字段的实际值为

这是我views/job_postings/_form.html.erb 如果你检查类别字段，那么它不是来自任何一个有数组的表，而是迭代它。

<%= form_for @job_posting do |f| %>
<% if @job_posting.errors.any? %>
        <div id="errors">
            <h2><%= pluralize(@job_posting.errors.count, "error") %> prevented this post from saving:</h2>
            <ul>
                <% @job_posting.errors.full_messages.each do |msg| %>

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

f.input :categories, as: :check_boxes, collection: f.object.categories似乎与activeadmin不兼容，所以我不确定你是否能够使用它。对于其他人，您需要包含要显示的集合，否则它似乎默认为是/否框。所以像这样：

  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

这应该让主动管理员知道您要使用类别可用的选项来填充复选框。

编辑：

请改为尝试：

  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

甚至：

<preference name="android-targetSdkVersion" value="20"/>

编辑表单复选框，radio和trix编辑器未在ActiveAdmin
