Django Query by Example (QBE)
|synopsis:||Admin tool in order to get custom reports.|
The objective of django-qbe is provide a assited and interactive way of making complex queries with no technical knowledge (or minimal) to get custom reports from the objects of Django models.
Based on QBE proposal from IBM®, django-qbe is intended to remove the limitations of Django QuerySets objects and to use the whole expresive power of the subjacent SQL.
Using the Python Package Index (PyPI) and easy_install script:
$ easy_install django_qbe
Or through pip:
$ pip install django_qbe
But you also can download the django_qbe directory using git:
$ git clone git://github.com/versae/qbe.git $ cp -r qbe/django_qbe /path/to/your/project
Adding to the project settings:
INSTALLED_APPS = ( # [...] django builtins applications 'django_qbe', # [...] Any other application )
And adding the urlconf in your project urls.py:
# qbe url(r'^qbe/', include('django_qbe.urls')),
You must not forgive link or copy the django_qbe/media/django_qbe directory in your project media directory:
$ ln -s django_qbe/media/django_qbe /path/to/your/project/media/
That's all. Then you can access to http://host:port/qbe However, you can add a link from your admin page changing the admin index template fo your AdminSite:
class AdminSite(admin.AdminSite): index_template = "qbe_index.html"
