[web2py] Re: SQLFORM.smartgrid selectable return string or list
You both are righ:
What's work now (also should worke before):
selectable=[('change price 100', lambda ids: modify_price(ids,100) ), ]
and the function in the same controller:
def modify_price(ids,inc):
print request.vars.records
print ids
print inc
Both request.vars.records and ids are lists also with only one selected
Thanks for help

Why do a redirect rather than simply doing the work in the same function?
Also, this redirect puts the ids in the URL query string, resulting in the
ultimate update being a GET request rather than a POST -- this is
undesirable because a refresh of that page will result in the entire
operation being repeated, which you don't want.

It's not that the function never gets called but that the function is not
written to work this way. The function expects to find ids in
request.vars.id, but that is actually None in the case where you call it
this way (the real values are in request.vars.records). Is modify_price a
controller action that needs to be accessible separately from this
particular operation? If not, just make it a helper function that accepts
an "ids" argument, and set selectable=modify_price.

[web2py] Re: SQLFORM.smartgrid selectable return string or list
Hi Icodk
I would see exactly what is being submitted by the browser. Open the 'web
developer' section in your browser and look at the 'network' traffic. When
you click your submit button, see what variables etc are being sent.
If your function is really being called, then try some print statements to
see what is being received by the function (you seem to be doing that).
Or, I guess you can also call your function directly from the lambda.
...
selectable= (lambda ids: modify_price(ids, 100)),
...
def modify_price(ids, incr):
#print ids, incr
db(db.product.id.belongs(ids)).update(
product_price=db.product.product_price + incr)

[web2py] Re: SQLFORM.smartgrid selectable return string or list
Hi Antony
My selectable looks like :
selectable = [('Add 100 to price',lambda ids: redirect(URL('product',
'modify_price', args=request.args, vars=dict(id=ids, inc=100,
and my function in the product controller looks like this:
def modify_price():
if type(request.vars.id) is str:
id_list = request.vars.id.split(',') #convertint to list
else:
id_list = request.vars.id
db(db.product.id.belongs(id_list)).update(product_price=db.product.product_price+request.vars.inc)
Simply following the documentation in the book
I also tried:
selectable= lambda ids: modify_price
But the function neve called
It should be request.vars.records, not request.vars.id.
Also tried with
def modify_rule_end_time():
print request.vars.records
and
def modify_rule_end_time(ids):
print ids
But again no error and the function was not called

[web2py] Re: SQLFORM.smartgrid selectable return string or list
It should be request.vars.records, not request.vars.id. Note, request.vars is processed by the core framework, not by SQLFORM.smartgrid, so it will be a single value if the browser sends only one "records" field in the form data and a list otherwise. The core code that populates request.vars has no way of knowing that a given field containing a single value is supposed to be a list -- that has to be handled elsewhere. SQLFORM.smartgrid itself handles this properly, but if you are going to intercept request.vars and run some custom code outside of the grid, then it is up to you to do the check and convert to a list. Keep in mind, the "selectable" argument to the grid should be a function that takes the list of ids -- presumably you can move your code into that function, in which case, you won't have to worry about this, as the grid will handle the conversion to a list.
