[Zope] Content Management

[Ria Marinussen]

Hi Don,

I've read the responses on your question so far and don't want to argue
about whether you should use DTML or PythonScript or whatever. 

I think however that your problem is in the ZSQL method. The variable names
in your database contain capitals. I think for entering (and updating) you
need to put the variable names in quotes when you use capitals, otherwise
Postgress or Zope (I don't know which one) assumes they are all small caps.

So I think it should be:
--
UPDATE A1
SET=
"A1_Title"= <dtml-sqlvar a1_Title type= "string">,
"A1_Author"= <dtml-sqlvar a1_Author type= "string">,
"A1_Body"= <dtml-sqlvar a1_Body type= "string">,
"A1_Pix1"= <dtml-sqlvar a1_Pix1 type= "string">,
"A1_Pix2"= <dtml-sqlvar a1_Pix2 type= "string">,
"A1_Date"= <dtml-sqlvar a1_Date type= "string">,
"Ai1"= <dtml-sqlvar ai1 type= "string">,
"Ai2"= <dtml-sqlvar ai2 type= "string">,
"Ai3"= <dtml-sqlvar ai3 type= "string">,
"Ai4"= <dtml-sqlvar ai4 type= "string">,
"Ai5"= <dtml-sqlvar ai5 type= "string">,
"Ai6"= <dtml-sqlvar ai6 type= "string">,
"Ai8"= <dtml-sqlvar ai8 type= "string">,
"Ai9"= <dtml-sqlvar ai9 type= "string">,
"Ai10"= <dtml-sqlvar ai10 type= "string">,
"A1_Publish"= <dtml-sqlvar a1_Publish type= "string">
WHERE
"A1_IDNum"= <dtml-sqlvar a1_IDNum type= "string">
--
 
Hope this helps.
