Define importers that load tabular data from spreadsheets or CSV files into any ActiveRecord-like ORM.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install active_importer
Define classes that you instruct on how to import data into data models.
class EmployeeImporter < ::
column 'First name', :first_name
column 'Last name', :last_name
column 'Department', :department do |department_name|
The importer defines what data model it imports data into, and how columns in the data source map to fields in the model. Also, by providing a block, the source value can be processed before being stored, as shown with the 'Department' column in the example above.
Once defined, importers can be invoked to import a given data file.
The data file is expected to contain columns with titles corresponding to the columns declared. Any extra columns are ignored. Any errors while processing the data file does not interrupt the whole process. Instead, errors are notified via some callbacks defined in the importer (see below).
