django-mindscape
- (todo: gentle introduction)
- (todo: add information about use case)
features
- collecting information about dependencies of models (model -> parent)
- collecting information about reverse dependencies of models (model -> [children])
- listing model with dependencies-considered order.
(dependencies-considered order means, when i < j, models[i] doesn't depends on models[j])
