I have a model with a virtual field:
db.define_table("tt",
Field("f"),
Field("gg"),
Field.Virtual("ff", lambda r:r.tt.f)
)
And a grid:
def t():
form = SQLFORM.grid(
db.tt,
)
return dict(form=form)
Works fine.
But with the *field argument* I get an error:
def t():
form = SQLFORM.grid(
db.tt,
*fields=[**db.tt.ff]*
)
return dict(form=form)
