Description (last modified by Russell Keith-Magee)

Django needs to provide the ability to evolve database schema - i.e., to update the database representation of project to reflect changes in the model definitions.

The design issues have been discussed here:

http://code.djangoproject.com/wiki/SchemaEvolution

A previous attempt at this feature exists in the form of the schema-evolution branch. This implementation is discussed here:

http://code.djangoproject.com/wiki/SchemaEvolutionDocumentation

However, this design has been rejected by the core developers.

Patch doesn't work against HEAD revision. Current trunk does not have management.py file.

For the benefit of anyone interested in this feature; the schema-evolution branch will *not* be merged as it currently stands. The design implemented by this branch has been discussed and rejected by the core developers. Feel free to use the patch and/or branch if you find it useful, but it will *not* become the official Django schema evolution implementation.

However, the underlying feature - providing a mechanism for evolving schema - *is* of interest. I've changed the subject, description and status of this ticket to reflect this.

See #5934 -- it rounds up the existing options, and is a nice placeholder until we can get a best-of-breed merged in.
