一个取决于ActiveAdmin形式的其他输入字段的输入

发布于 2025-02-12 19:47:35 字数 381 浏览 0 评论 0 原文

假设我有一个模型：

class User
 has_many :books
end

class Book
 belongs_to :user
end

现在在Active Admin中，我需要选择任何用户时。该表格将仅显示由该用户创建的书籍。

forms do |f|
 f.inputs do
  f.input :user, as: :select, collection: User.all
  f.input :books, as: :select,  collection: Book.all
 end
 f.actions
end

什么是替换 book.all 的查询？

原文

Let's say I have a model:

class User
 has_many :books
end

class Book
 belongs_to :user
end

Now in active admin, I want when I select any user. The form will only display books created by that user.

forms do |f|
 f.inputs do
  f.input :user, as: :select, collection: User.all
  f.input :books, as: :select,  collection: Book.all
 end
 f.actions
end

What is the query to replace Book.all?

我对Rails 6.0.4

模型

class Organization < ApplicationRecord 
 belongs_to :sector
 belongs_to :sub_sectors
end

class Sector < ApplicationRecord 
 has_many :sub_sectors
end

class SubSector < ApplicationRecord 
 belongs_to :sector
end

主动admin表单上的依赖性“选择”的这项工作

ActiveAdmin.register Organization do
  form do |f|
    f.inputs "Details" do
        f.input :sector, as: :select, collection: Sector.all
        f.input :sub_sector_id, as: :select, collection: ([]) # The input is initialized without values
    end
    f.actions
  end
end

您必须执行以下操作：

创建一个控制器，以返回子行业。

  class costorsController＆lt; ApplicationController

  def sub_sectors_filter
    如果参数[：sector_id]
      sector = sector.find（params [：sector_id]）
      @sub_sectors = sector.sub_sectors
    别的
      @sub_sectors = []
    结尾
    渲染：json =＆gt; @sub_sectors.collect {| sub_sector | {：id =＆gt; sub_sector.id，：name =＆gt; sub_sector.name}}
   结尾

结尾

在 doutes.rb 文件中添加路由。

 获取'sub_sectors_filter/'=＆gt; 'sub_sectors＃sub_sectors_filter'

使用您的Web浏览器控制您的选择您的选择，并使用CSS选择器为Select创建jQuery对象，例如：
```
  $（'＃andurand_sector_id'）
 
```

在文件/app/app/asps/javascripts/active_admin中添加此代码块。 JS ，负责调用生成的控制器，并添加其返回的选项。

  // =需要Active_admin/base
$（function（）{
  美元
    $（'＃andurans_sub_sector_id选项'）。remove（）; //删除All＆lt;选项＆gt;子标签。
    $ .getJSON（`/sub_sectors_filter`，{sector_id：$（$（this）.val（）}，function（result）{// getjson上的文档：http://api.jquery.com/jquery.com/jquery.com/jquery.getjson/
      $。each（结果，函数（i，item）{//通过集合进行迭代
        美元
            价值：item.id，
            文字：item.Name 
        }））;
      }）;
    }）;
  }））
}））

无法在我的依赖选择下拉admin上找到错误（Rails 3.2，Active Admin 1.0）

This work for me on dependend "select" on Rails 6.0.4

Models

class Organization < ApplicationRecord 
 belongs_to :sector
 belongs_to :sub_sectors
end

class Sector < ApplicationRecord 
 has_many :sub_sectors
end

class SubSector < ApplicationRecord 
 belongs_to :sector
end

Active admin form

ActiveAdmin.register Organization do
  form do |f|
    f.inputs "Details" do
        f.input :sector, as: :select, collection: Sector.all
        f.input :sub_sector_id, as: :select, collection: ([]) # The input is initialized without values
    end
    f.actions
  end
end

You must do the following:

Create a controller, that returns the subsectors.

class SubSectorsController < ApplicationController

  def sub_sectors_filter
    if params[:sector_id]
      sector = Sector.find(params[:sector_id])
      @sub_sectors = sector.sub_sectors
    else
      @sub_sectors = []
    end
    render :json => @sub_sectors.collect {|sub_sector| {:id => sub_sector.id, :name => sub_sector.name} }
   end

end

Add the route in the routes.rb file.

get 'sub_sectors_filter/' => 'sub_sectors#sub_sectors_filter'

Inspect with your web browser console your selects, and use a CSS selector to create a jQuery object for the sector select, something like:
```
$('#organization_sector_id')
```

Add this block of code in the file /app/assets/javascripts/active_admin.js, which is responsible for making the call to the generated controller, and adding the options that it returns.

//= require active_admin/base
$(function () {
  $('#organization_sector_id').on('change', function () {
    $('#organization_sub_sector_id option').remove(); // Remove all <option> child tags.
    $.getJSON(`/sub_sectors_filter`, {sector_id: $(this).val()}, function(result){ // Documentation on getJSON: http://api.jquery.com/jQuery.getJSON/
      $.each(result, function (i, item) { // Iterates through a collection
        $('#organization_sub_sector_id').append($('<option>', { // Append an object to the inside of the select box
            value: item.id,
            text : item.name 
        }));
      });
    });
  })
})

AS sampat 在评论中提到您可以使用activeadmin 嵌套选择插件。

安装 activeadmin_addons GEM后，您可以使用：

  forms do |f|
    f.inputs do
      f.input :user_id, as: :nested_select,
                        level_1: { attribute: :user_id, collection: User.all },
                        level_2: { attribute: :book_id, collection: Book.all }
    end
    f.actions
  end

As Sampat mentioned in the comment you can use ActiveAdmin nested select addon.

After installing activeadmin_addons gem, you can use:

  forms do |f|
    f.inputs do
      f.input :user_id, as: :nested_select,
                        level_1: { attribute: :user_id, collection: User.all },
                        level_2: { attribute: :book_id, collection: Book.all }
    end
    f.actions
  end
