[Toaster] question about "build.target_set"

[Lerner, Dave]

See https://docs.djangoproject.com/en/1.5/topics/db/queries/#backwards-related-objects

" 
Following relationships "backward"
----------------------------------
If a model has a ForeignKey, instances of the foreign-key model will have access to a Manager that returns all instances of the first model. By default, this Manager is named FOO_set, where FOO is the source model name, lowercased. This Manager returns QuerySets, which can be filtered and manipulated as described in the "Retrieving objects" section above.
"

and https://docs.djangoproject.com/en/1.5/topics/db/queries/#field-lookups-intro

" Django also creates API accessors for the "other" side of the relationship - the link from the related model to the model that defines the relationship. For example, a Blog object b has access to a list of all related Entry objects via the entry_set attribute: b.entry_set.all()"


So for B=build.objects.get(id=1)
b.target_set.all() returns all targets related to the build object b.
