Data Imp Porter

Add this line to your application's Gemfile:

gem 'data_imp'

And then execute:

$ bundle

Or install it yourself as:

$ gem install data_imp

The use of this gem requires that you define an 'importer' for your files.

the fields from your data will be available to the importer as if they were local variables.

class SampleImporter < DataImp::Porter
  def import
    User.create_with(
      name: name,
    ).find_or_create_by(
      email: email
    )
  end
end

If you had your users in a csv file like

name,email
George,george@example.com
Fred,fred@example.net

You could then use

DataImp.import 'user.csv'

If you had your users in a yaml file like

---
- name: George
  email: george@example.com
- name: Fred
  email: fred@example.net

You could then use

DataImp.import 'user.yaml'

The same importer would be used for either example.

The importer is looked up by the base name, or provided by the importer: parameter. . 'user' in this case.

Parsing of the file is done by a Parser class and is looked up by the file extension, or the parser: parameter.

Pre defined parsers are located in the lib/data_imp/parsers/ folder

If you need to write your own, define it as 'class ExtParser < DataImp::Parser' to create or override the 'ext' extension parser.
