Description (Last modified by russellm)

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.

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.
