This gem exports model data into different formats, such as CSV. To achieve so, it uses an export model that handles how the data will be shown.
Example:

class ExampleExportModel
  def initialize(example)
    @example = example
  end

  def export_header
    ['Code', 'Name', 'Random Number', 'Created At', 'Updated At']
  end

  def export
    [code, name, random_number, created_at, updated_at]
  end

  private

  def code
    @example.code
  end

  def name
    @example.name
  end

  def random_number
    @example.random_number
  end

  def created_at
    @example.created_at
  end

  def updated_at
    @example.updated_at
  end
end

Exporting the data:

DataExporter::Exporter.new(example, :csv).export

Exporting the data to a tempfile:

DataExporter::Exporter.new(example, :csv).export_to_tempfile

0.1.0: Initial version, only CSV is supported
0.1.1: Change format in initializer to symbol instead of string
