I don't get all my db.table fields form define_table fields defined...
A other guy report that... But didn't find exactly why his compute
functions as stop working properly...
To me it's related to the fact tha if I do :
Field('mycomputefield', compute=lambda r: r)
I am not getting all the fields.
For example:
db.define_table('test1',
Field('f1','string'),
Field('f2','integer'),
Field('computefield',compute=lambda r: r))
Will return only field that appear in form, so if I set f1 to
writable=False, it will not be in form so it will not be available to
compute function...
I think it for make compute failed silently if some fields are set to
writable or readable = False... But I would return all the field to compute
with a "None" for empty field instead of not returning any key... I really
don't know if it even possible, if it is a bug or something else...
I work around issue I were having with compute (I would compute a md5 hash
for row so I would have all key/value pairs even if one of those were
empty, but I can't with compute), so I use the new virtual field style
(hope it will stay).
Here the thread I am refering to :
