Something is wrong with this:
db.define_table('dogs',
...
Field('vaccination_id', db.vaccinations))
db.define_table('vaccinations',
Field('dog_id', db.dogs),
...
)
there is a circular definition and seems to indicate each dog can have
a single vaccination.
I would go with this:
db.define_table(
'users'
Field('name')
)
db.define_table(
'dogs',
Field('owner_id', db.users),
Field('name'),
)
db.define_table(
'vaccinations',
Field('dog_id'),
Field('vaccination')
)
You can do things like:
form=SQLFORM.factory(db.dogs,db.vaccinations)
but you have to be careful about repeated fields.
If you describe the workflow of what you need to do perhaps we can
help more.
