django-batchimport

Allows for batch import of django model data via uploaded Microsoft Excel files, saved as XLS files (Excel Binary file format). Of course, you can also use OpenOffice or CSV files, but you will have to convert them to the XLS format beforehand.

Some screenshots of SynCoor used in a document management application are available here.

This experimental forks uses "class-based views" to provide more flexibility

object_id : Database ID of the object created/updated

error_messages is made of a list of dicts with the following keys :

name : Name of the error

Session data

django-batchimport uses the following session variables to store data between its views n:

batchimport_file_name (set by ImportUploadView)
batchimport_model (set by ImportUploadView)
batchimport_options (set by ImportOptionsView)
batchimport_info (set by ImportOptionsView)

These variables are erased at the end of the import operation (in ImportRunView.run_import())

WARNING: Because the batchimport_info is a ModelImportInfo object (django-batchimport specific class), and ModelImportInfo is not JSON-serializable, it is not possible to use JSON serialization to store your session data.

Installation

pip install git+git://github.com/pstch/django-batchimport.git

Or clone http://github.com/pstch/django-batchimport.git and install package yourself using setup.py.

Configuration

Add batchimport to INSTALLED_APPS in settings.py

Generic URL config

If you want to use django-batchimport's own URL config :

Add the following URL pattern in urls.py : (r'^batchimport/', include('batchimport.urls')),

Subclassing django-batchimport views

But you can also subclass the three views ImportUploadView, ImportOptionsView and ImportRunView in order to set your own settings and also your own URL patterns.

Just remember that whenever you change a URL pattern's name, you have to change it accordingly in the upload_url and options_url view attributes, and in the templates.
