[Zope] newbie DTML namespace

2000-07-27 Thread Brad Moulton 

Hi all,

as a newbie to both python and zope i am struggling with understanding the
howto and the syntax of accessing stuff in namespace

eg

I would like to build a table depending on some tests peformed on stuff
returned form a Z SQL method

1. I have a form with a name="spam" value="egs"
this value is passed onto next dtml document
-
table
tr
tddtml-var spam td// displays 'eggs'  to test spam is OK
/tr
dtml-var sqlstuff // this does a join of two tables 
dtml-in sqlstuff
dtml-if {CAN'T WORK OUT SYNTAX TO ACCESS  spam to compare with lets say
sqlstuff.spam}
trtddtml-var sqlstuff.column/tdetc
/dtml-if
/dtml-in  
--
I have read DTML  Reference but dtml-if says "a valid python expression"
Can I still access spam inside the dtml-in if so how dtml-var spam, spam
'spam', ['spam']
and then how do i refer to a table column name returned in the SQL
query  to make the comparison 

TIA
brad

Your problem is solved by renaming.

You can either rename your DTML var or your SQL column result name:

DTML var:

  dtml-let myspam=spam !-- you can now access "spam" as "myspam"--
dtml-in sqlstuff
   
   dtml-if "myspam == spam"/dtml-if
   
/dtml-in
  /dtml-let

SQL column result name:

  select spam as sqlspam ...

You now access the "spam" column under the name "sqlspam".


I, regularly, use SQL column renaming.
