Question

我是RoR的初学者，我想在林管理中为导入数据（csv）实现自定义操作。 http://doc.forestadmin.com/developers-guide/#triggering-an-action-from-the-collection

我有我的actions_controller（controllers / forest / actions_controller.rb）：

class Forest::ActionsController < ForestLiana::ApplicationController
  require 'data_uri'
  def bulk_import
    uri = URI::Data.new(params.dig('data', 'attributes', 'values', 'file'))
    uri.data.force_encoding('utf-8')
    CSV.parse(uri.data).each do |row|
      Geo.create!({
        :departement=> row[0],
        :slug => row[1],
        :nom => row[2],
        :nom_simple => row[3],
     })
    end
    render json: { success: 'Data successfuly imported!' }
  end
end

我的收藏（lib / forest_liana / collections / geo.rb）：

class Forest::Geo
  include ForestLiana::Collection
  collection :geos
  action 'bulk_import', global: true,
  fields: [{
    field: 'importer csv', type: 'File', isRequired: true, description: "Personal description",
  }]
end

我添加了我的路线：

namespace :forest do
  post '/actions/bulk_import' => 'actions#bulk_import'
end

这不起作用......：/

Answer 1

在您的配置中，该字段名为importer csv，因此该字段名称将在请求中发送。

在 lib / forest_liana / collections / geo.rb

中

class Forest::Geo
  include ForestLiana::Collection
  collection :geos
  action 'bulk_import', global: true,
  fields: [{
    field: 'importer csv', type: 'File', isRequired: true, description: "Personal description",
  }]
end

在您的控制器中，您应该：

uri = URI::Data.new(params.dig('data', 'attributes', 'values', 'importer csv'))

而不是：

uri = URI::Data.new(params.dig('data', 'attributes', 'values', 'file'))

看起来importer csv应该是操作的名称，而不是字段。

如果你想这样命名你的行动，这是合适的配置：

class Forest::Geo
  include ForestLiana::Collection
  collection :geos
  action 'Importer CSV', global: true,
  fields: [{
    field: 'importer csv', type: 'File', isRequired: true, description: "Personal description",
  }]
end

快速建议在类名上面写require 'data_uri'。
