[reportlab-users] Newbie - Basic BaseDocTemplate

[Riaan Bekker]

I can not get my BaseDocTemplate example to work.

 

If I move the BaseDocTemplate.__init__(self,name) after my variable
declaration, it never gets executed, if I move it before my variable
declaration, it never executes my variable declares. I am newbie to this, so
still struggling with it.

 

I also did not get the self.canv variable before, but I hope with this kind
of sub-classing that I can get hold of it and creaty my frames. Am I on the
right track here ? I just want to do a page with 3 columns and the top and a
detail section below that 2 columns, that is why I used 3 frames at the top,
and 1 frame for the body. The body will contain some kind of grid to display
row data, the top 3 frames will display data from static tables, but still
needs to be populated from the database. Where will be the best to populate
the tables and grid? I am connecting to a postgre-sql DB and also to
Microsoft GP.
