Hello,
I don't understand why I have to redefine my compute field function...
I have a compute field like this one :
# model
db.define_table('mytable',
Field('f1', 'string'),
Field('review', 'boolean'),
Field('record_review_status', compute=lambda record:
return_computed(record, request.args(0)))
# contoller
def fun():
form = SQLFORM.factory(Field(...))
session.rows = db(db[request.args(0)].review == False).select()
table = SQLTABLE(session.rows...)
form.process().accepted:
for r in session.rows:
row = db[request.args(0)](r.id)
row.update_record(review='TRUE')
db.commit()
row = db[request.args(0)](r.id)
*row.record_review_status = return_record_review_status(row,
request.args(0)) # here I need to redefine my record_review_status compute
field or it not get computed*
row.update_record()
db.commit()
...
Note : It is pseudo code, so it may seems dumb or not working, I just try
to make an example of what going on in my app...
In the book it is said that if we try to update record without passing,
web2py tries to compute compute field base on orther field value...
http://web2py.com/books/default/chapter/29/06?search=compute#Computed-fields
By the way, this part of the book is not pretty clear... For instance do I
have to leave update() of update_record() blank in order to get my compute
field to be computed.
Also, it is not exactly clear to me why my compute field not get compute on
row.update_record(review='TRUE')... What I understand is that I need to
explicitly update my compute field, but the way to do it seems to passing
not paramaters to update() or update_record().
In my case, it seems that my compute function can't get the 'TRUE' for
review only once the update(review='TRUE') is committed... I try to remove
the line in bold, because it already in my model, but it is not working, my
compute field never get updated it status.
Thanks to clarify this to me.
Richard
