django-tablib is a helper library for Django that allows Django models to be used to generate tablib datasets with introspection of the fields on the models if no headers are provided. If headers are provided they can reference any attribute, fields, properties, or methods on the model.

django-tablib: tablib for Django

django-tablib is a helper library for Django that allows tablib datasets to be generated from Django models.

Overview

django_tablib.ModelDataset()
A wrapper around tablib.Dataset that handles the conversion of Django QuerySets to a format that tablib can work with in the model of Django's ModelForm and ModelAdmin.

Usage

The below examples are all based on this model:

from django.db import models

class MyModel(models.Model):
    myfield1 = models.TextField()
    myfield2 = models.TextField()

Create a tablib Dataset from a Django model, automatically introspecting all fields from the model:

from django_tablib import ModelDataset
from myapp.models import MyModel

class MyModelDataset(ModelDataset):
    class Meta:
        model = MyModel

# This dataset will have the fields 'id', 'myfield1' and 'myfield2'.
data = MyModelDataset()

Create a tablib Dataset from a Django model, including only certain, desired fields:

from django_tablib import ModelDataset
from myapp.models import MyModel

class MyModelDataset(ModelDataset):
    class Meta:
        model = MyModel
        fields = ['id', 'myfield1']

# This dataset will have the fields 'id', and 'myfield1'.
data = MyModelDataset()

Create a tablib Dataset from a Django model, excluding certain, undesired fields:

from django_tablib import ModelDataset
from myapp.models import MyModel

class MyModelDataset(ModelDataset):
    class Meta:
        model = MyModel
        exclude = ['myfield2']

# This dataset will have the fields 'id', and 'myfield1'.
data = MyModelDataset()

Create a tablib Dataset from a Django model declaratively specifying the fields to be used:

from django_tablib import ModelDataset, Field
from myapp.models import MyModel

class MyModelDataset(ModelDataset):
    myfield1 = Field()
    myfield2 = Field()

    class Meta:
        model = MyModel

# This dataset will have the fields 'id', 'myfield1' and 'myfield2'.
data = MyModelDataset()

Create a tablib Dataset from a Django QuerySet:

from django_tablib import ModelDataset
from myapp.models import MyModel

class MyModelDataset(ModelDataset):
    class Meta:
        queryset = MyModel.objects.filter(is_awesome=True)

# This dataset will have the fields 'id', 'myfield1' and 'myfield2'.
data = MyModelDataset()

Create a tablib Dataset from a Django model declaratively specifying fields and their headers:

from django_tablib import ModelDataset, Field
from myapp.models import MyModel

class MyModelDataset(ModelDataset):
    myfield1 = Field(header='No More Boring Field Names!')

    class Meta:
        model = MyModel

# This dataset will have the fields 'id',
# 'No More Boring Field Names' and 'myfield2'.
data = MyModelDataset()

Add a new row:

>>> data.append(MyModel(**values))

Add a new column:

>>> data.append(col=['header', 'value1', 'value2' ... 'valuen'])

Delete a row:

>>> del data[1]

For everything else see the tablib documentation!

Django Integration

django_tablib.views.export

django_tablib provides a generic Django view to automatically export your querysets to an Excel spreadsheet. In your urls.py:

(r'^export/$', 'django_tablib.views.export', {
    'model': MyModel,
})
django_tablib.views.generic_export
If you have many models to export you may prefer use the generic export view:
  1. Add the view to urlpatterns in urls.py:

    url(r'export/(?P<model_name>[^/]+)/$', "django_tablib.views.generic_export"),
    
  2. Create the settings.TABLIB_MODELS dictionary using lower-case model names in "app.model" format as keys and the permitted field lookups or None as values:

    TABLIB_MODELS = {
        'myapp.simple': None,
        'myapp.related': {'simple__title': ('exact', 'iexact')},
    }
    
  3. Open /export/myapp.simple or /export/myapp.related/?simple__title__iexact=test

django_tablib.admin.TablibAdmin

For easy exporting of your models directly from the Django admin, django_tablib now provides a ModelAdmin subclass giving you a button to export to Excel straight from the change list:

from django.contrib import admin
from django_tablib.admin import TablibAdmin
from myapp.models import MyModel

class MyModelAdmin(TablibAdmin):
    formats = ['xls', 'json', 'yaml', 'csv', 'html',]

admin.site.register(MyModel, MyModelAdmin)

You can also customize which fields from MyModel are used by supplying a headers list:

from django.contrib import admin
from django_tablib.admin import TablibAdmin
from myapp.models import MyModel

class MyModelAdmin(TablibAdmin):
    formats = ['xls', 'json', 'yaml', 'csv', 'html',]
    headers = ['field_one', 'field_two',]

admin.site.register(MyModel, MyModelAdmin)

That's it!

Compatibility

django-tablib has been tested with Django 1.4. On Django 1.5 it does throw a deprecation warning (see issue #25).
