Telega Megaimport

Framework for parsing CSV, XSL, Google Spreadsheets into Django.

Install package with pip install telega_megaimport

Add 'telega_megaimport' to your project's INSTALLED_APPS

To create new parser, use ./manage.py create_parser command Specify --appdir (directory of app, where parser should be created) and --filename (name of parser)

Inside new parser, declare cells as they go in parsed document (exact order matters!)

Every cell has next args:

• required (boolean, if cell is required for row to work correctly)
• default (arbitraty, if cell has some default value) Available cell types:
• EmptyColumn (for cells you want to skip)
• StringColumn (for string-containing cells; use arg 'strip' (boolean) to turn on/off strip on parse)
• IntegerColumn
• FloatColumn
• BooleanColumn (will recognize ['yes', 'y', '+', '1', 'true'] as True, ['no', 'n', '-', '0', 'false'] as False)
• ModelColumn (queryset should be declared, lookup_arg by default = 'pk', but can be changed. Returns model (one and only one!) responding by lookup)
• ModelTypeColumn (app_label should be declared if model is ambigious)
• StatusColumn (list or tuple of parse_ready_statuses shpuld be declared. Row will be parsed only if all StatusColumns are parse-ready)

In newly created parser:

• Override method row(values) to process result of row-parsing
• Override method attr_name_handler to prosess result of single cell parsing

To run new parser, use ./manage.py <parser_name> [way_to_file] Next options are supported: --header - Is there header in file? (default - True) --sheet - specify .xls sheet name. Will use first one if nothing specified --progress - set 'True' to use progressbar. Default - False. If True, progressbar module is required --failfast - set 'True' to stop parsing on first error --dryrun - set 'True' to perform parsing without commiting data into database --savestats - set 'True' to collect after-parse statistics into file --google_spreadsheet - set 'True' if you are parsing google-spreadsheet directly (gspread module required)

Requirements:

• Django >= 1.7
• xlrd (for .xls parse)
• gspread (Optional; for parsing Spreadsheets)
• progressbar (Optional; for ProgressBar generation)

To Be Done:

• Improved test coverage
• Better documentation
