sourcelabsllc / administrate_exportable Goto Github PK

Add this line to your application's Gemfile:

gem 'administrate_exportable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install administrate_exportable

For each resource you want to be exportable, add the following line to the their respective Administrate controller.

include AdministrateExportable::Exporter

and the following line in the config/routes.rb file, correctly nested on resources

get :export, on: :collection

Example:

namespace :admin do
  resources :organizations do
    get :export, on: :collection
  end
....

By default all the attributes from ATTRIBUTE_TYPES will be exported. If you want to exclude an attribute, you can use the option: export: false.

Example:

class BusinessDashboard < Administrate::BaseDashboard
  ATTRIBUTE_TYPES = {
    id: Field::Number.with_options(export: false),
    name: Field::String,
    description: Field::Text,
...

For the default field types from Administrate, we export the values you got from the partial views/fields/index. And if it is a custom field, we just run field.to_s. But if you want to specify the value to be exported, you can use the option transform_on_export, to pass a Proc that receives the field. Example:

ATTRIBUTE_TYPES = {
 created_at: Field::DateTime.with_options(transform_on_export: -> (field) { field.data.strftime("%F") })

By default the gem adds the Export button to the partial views/admin/application/_index_header.html.erb. But if you have your own Administrate index views or override that partial in your application you can add the link manually:

link_to('Export', [:export, namespace.to_sym, page.resource_name.to_s.pluralize.to_sym, sanitized_order_params(page, :id).to_h.merge(format: :csv)], class: 'button') if valid_action?(:export)

Example:

....
 <div>
    <%= link_to(
      t(
        "administrate.actions.new_resource",
        name: page.resource_name.titleize.downcase
      ),
      [:new, namespace.to_sym, page.resource_path.to_sym],
      class: "button",
    ) if valid_action?(:new) && show_action?(:new, new_resource) %>

    <%= link_to(
      'Export',
      [:export, namespace.to_sym, page.resource_name.to_s.pluralize.to_sym, sanitized_order_params(page, :id).to_h.merge(format: :csv)],
      class: 'button'
    ) if valid_action?(:export) %>
  </div>
....
