Sorry, this is (part of) my db.py:
db.define_table('contenido', \
Field('titulo'), \
Field('slug'), \
Field('fecha_hora', 'datetime'), \
Field('detalle', 'text'), \
Field('cuerpo', 'text'), \
Field('autor'), \
Field('meta_description'))
db.define_table('galeria_contenido', \
Field('contenido', db.contenido, ondelete='NO ACTION'), \
Field('orden', 'integer'), \
Field('titulo'), \
Field('detalle', 'text'))
On the other hand, a controller with a function that tries to delete a
"noticia" (spanish for "news"):
def _eliminar_borrador():
noticia = db.contenido[request.post_vars.noticia]
noticia.galeria_contenido.delete()
db(db.contenido.id==noticia.id).delete()
return response.json({'success':True})
The line that throws the error is this:
noticia.galeria_contenido.delete()
Here I post again the traceback:
Traceback (most recent call last):

File "/home/gonguinguen/medios/gluon/packages/dal/pydal/helpers/classes.py",
line 348, in __getattr__
raise AttributeError
AttributeError
That sentence is executed without errors if I write it this way:
db(db.galeria_contenido.contenido==noticia.id).delete()
I think both sentences are valid. The first one only fails with web2py
2.11.2, but works ok with 2.10.3.
