ActiveAdminImportable

CSV imports for Active Admin with one line of code.

My fork includes:

fixed active_admin dependency issue
added a possibility to specify options for CSV.parse (example below)
AR transaction wrapping (you may need to raise ActiveRecord::Rollback by yourself in your save code though)
very basic error handling
you can now pass additional hash of options for rendering custom partials, like:

active_admin_importable({:col_sep => ";"}, {:form => "path/partial", :bottom => "path/partial"}) do |model, hash|
    #stuff
end

Installation

Add this line to your application's Gemfile:

gem 'active_admin_importable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_admin_importable

Usage

Add the following line into your active admin resource:

active_admin_importable

The Import button should now appear. Click it and upload a CSV file with a header row corresponding to your model attributes. Press submit. Profit.

Custom Import Behavior

Need to do something special with the import? active_admin_importable accepts an optional block that will be called on each row, replacing the default functionality ( calling create! on the associated model). The associated model and a hash of the current row will get passed into the block. For example:

ActiveAdmin.register Product do
   active_admin_importable do |model, hash|
      store = Store.find_by_name(hash[:store_name])
      hash[:store_id] = store.id
      hash.delete(:store_name)
      model.create!(hash)
   end
end

Parsing Options

ActiveAdminImportable uses CSV.parse to parse your uploaded CSV. You can pass in any standard options via the optional param to active_admin_importable:

ActiveAdmin.register Product do
  active_admin_importable(
    col_sep: ':',
    quote_char: "'",
    header_converters: ->(h) { h.underscore.to_sym }
  )
end
