django-qbe

It is a data query tool for data stored in Django objects.

django-qbe is a Django implementantion for Query By Example (QBE) by IBM.

It is intended to remove the limitations of Django QuerySets objects and to use the whole expresive power of the subjacent SQL.

Features:

• Multi-database support.
• View and autodiscover relations among the models in a visual way (ForeignKey fields are green and ManyToMany ones are red).
• Tabular creation of queries with fields to show, criterias, lookups and order (only AND conditions by now).
• Auto addition of right fields when ForeignKey or ManyToMany fields are selected.
• No models in the project, so you can add django-qbe whenever you want with no syncdb.
• Pagination of results.
• Bookmarklet to save and share the queries.
• Export results to .csv, .odt and .xls, but it's extensible by the user.
• Access restricted to users through a customizable function.
• Links to admin views (if available) in the results objects.
