Why 1? .table is there exactly to allow you to do what you are trying to
do. I would do:
pth = "test.db"exists = os.path.exists(pth)
# migrate_enabled false prevent to create a .tablesdb =
dal.DAL("sqlite://{}".format(pth)) # 1
db.define_table("dynamic_fields", Field("f_name")) # 2, 4if *exists*:
db.dynamic_fields.insert(f_name="dynamic")
base_fields = [Field("attr0")]
other_fields = [Field(r.f_name) for r in
db(db.dynamic_fields).select()]db.define_table("foo",
*(base_fields+other_fields))
