Import/Export data between Excel/CSV and Rails/Ruby applications.
Bulk attach multiple files easily to Paperclip models.
Comprehensive Wiki here : https://github.com/autotelik/datashift/wiki
Add gem 'datashift' to your Gemfile/bundle or use
Win OLE and MS Excel are NOT required.
To use the Thor command line applications, pull in the tasks.
Create or add to a high level .thor file in your lib/tasks or root directory
Edit the file and add the following to pull in the datashift thor commands :
require 'thor' require 'datashift' DataShift::load_commands
To keep the availability to only development mode use
To check the available tasks run
bundle exec thor list datashift
To get usage information use thor help , for example
bundle exec thor help datashift:generate:excel
Use CSV or Excel/OpenOffice/LibraOffice etc (.xls) files to Import or Export your database (ActiveRecord) models
Bulk import tools from filesystem, for Paperclip attachments, takes folder of attachments such as images/mp3s/files and use the file name to find and attach to DB models. For example look up a product, by it's '''SKU''', based on the SKU being present the image filename, and attache that image to the product's '''images''' association
Supports export of all association types, in either hash or json formats.
Association types to include/exclude can be set in configuration as well as speciifc columsn to exclude.
Rails standard columns such as id, created_at etc can also be easily excluded via Configuration.
Set default values, substitutions and transformations per column for Imports.
Generate sample templates, with only headers.
Export template and populate with model data.
Please use thor list and thor help to get latest command lines, for example
'''ruby bundle exec thor datashift:import:csv --model BlogPost --input BlogPostImport.csv '''
Imports are based on column headings with Semi-Smart Name Lookup
On import, a dictionary of all possible attributes and associations is created for the AR class.
This enables lookup, of a user supplied name (column heading), managing white space, pluralisation etc .
Example usage, load from a file or spreadsheet where the column names are only an approximation of the actual associations, so given 'Product Properties' heading, finds real association 'product_properties' to send or call on the AR object
Can import 'belongs_to, 'has_many' and 'has_one' associations, including assignment of multiple objects via either multiple columns, or via single column containing multiple entries in json/HASH format.
See Wiki for more details on DSL syntax.
You can now configure datashift with a standard initialisation block
To generate a configuration file template, for import see
thor help datashift:generate:config:import
Specs run against a rails sandbox app, so have own Gemfile, so you can specify versions of active record that you want specs to run against : Edit
Then run :
cd spec bundle install
A sandbox will be generated in spec/sandbox if no such directory exists. **N.B Manual Step** When changing versions you probably need to **delete this whole directory** spec/sandbox. Next time you run spree specs it will be auto generated using latest Rails versions The database are created in sqlite3 and are stored in spec/fixtures. When switching versions, of say Spree, you will probably want to and to clear out old versions and retrigger the migrations rm spec/fixtures/*.sqlite You will probably also want to remove lock file : rm spec/Gemfile.lock First time the sandbox is regenerated, alot of tests may fail,perhaps not everything loads correctly during regeneration process. Invariably the next run, the specs pass, so a fix is low priority.
Run the Tests
** N.B You should run the specs from within the specs directory. **
bundle exec rspec -c .
A datashift **log **will be written within **spec/logs**, which hooks into the standard active record logger /log/datashift.log spec/logs/datashift_spec.log
