One final question if I may (well I hope its the last).
In my standard report generating view I need to use Arial font (for
example).
I have studied the reportlab docs (Paragraphs chapter) for hours and
tried all sorts of guesses as to how to do it. Nothing I have tried
works. My fault. Now
In my report generating view I have this (snip):
if tablename == 'Area':
areas = Area.objects.all()
data.append(['Code','Name','Description'])
for area in areas:
data.append([
Paragraph(area.area, normalstyle, bulletText=None),
