- loaddata migration south
- 0 (after 0 ratings)
A very simple way of automatically loading data on model creation.
As I am using South I wanted an automatic way of loading initial data only when a new model is create during a migration. Django provides almost everything out of the box by providing the post_syncdb signal (triggered also by South migrate command) and the loaddata command.
The code will simply look for a an existing fixture named
<model>_initial.* and invoke the loaddata command to try to load it
Note: beware post_syncdb signal is deprecated since version 1.7: it has been replaced by post_migrate.
