Hi,
This weekend I did some work on python scripts and found some things which
suprised me, can someone enlighten me on this why these 'strange' things are
needed? :
1. When calling a method from a python script you've to do this :
(assume x is the value to pass and name is a parameter of mymethod)
context.mymethod(name=x)
The following doesn't works :
context.mymethod(x) (this gives an error)
Why????
2. Assume you've an sqlmethod which expects 2 parametes, but one is optional
:
eg
select *
from invoice
<dtml-sqlgroup where required>
<dtml-sqlgroup>
<dtml-sqltest customersid column=customers_id op=eq
type=int>
<dtml-and>
<dtml-sqltest productsid column=products_id op=eq type=int
optional>
</dtml-sqlgroup>
</dtml-sqlgroup>
So, you could run this sql with or without the productsid
No, calling from python script doesn't works since it
expects: context.mymethod(customerid=..., productsid=...)
while context.mymethod(customerid=...) doesn't work..
Now, this implies that I've to write 2 sqlmethods (one with 2 parameters and
one with 1),
which is pretty stupid, since sqlmethods perfect allow to ignore a parameter
when not passed...
Can somebody tell me more on this? Why this is the case and perhaps a
solution for (2)
Thanks in advance,
