I did this in a Form subclass but I later took it out so I don't have the
code. Attach the HTML to a widget attribute or method (I used .before,
meaning before the widget.) Override Form._render_widgets something like
this:
def _render_widgets(self):
r = TemplateIO(html=True)
for widget in self.widgets:
try: # Stanza added.
r += widget.before
except AttributeError:
pass
r += widget.render()
return r.getvalue()
Because each widget puts a <DIV> around itself, your addition will show up
on a separate line. This code works only for regular widgets, not child
(composite) widgets or submit widgets.
Likewise, you can override Form._render_body to add some extra HTML at the
top or bottom of the form. I use this to add a "* means required"
message.
REQUIRED_MESSAGE = htmltext(
'<BR><SPAN CLASS="required">*</SPAN> indicates required field.')
class Form:
def _render_body(self):
"""Add required notice."""
r = TemplateIO(html=True)
if self.has_errors():
r += self._render_error_notice()
r += self._render_required_notice() # Line added.
if self.caption:
r += self.caption
r += '\n'
r += self._render_widgets()
r += self._render_submit_widgets()
return r.getvalue()
def _render_required_notice(self):
for widget in self.widgets:
if widget.is_required():
break
else:
return '' # No required widgets.
return REQUIRED_MESSAGE
