Massimo, {{=BEAUTIFY(response._vars.values()[0])}} is still preferred
in case the controller returns something like {'': ['a', 'b', {'foo':
'bar'}]}
By the way, here is another proposal. Since you agree on at least "let
me think", please also consider change the generic.html into this.
<!-- A more generic generic.html -->
{{extend 'layout.html'}}
{{if len(response._vars)==1 and not response._vars.keys()[0]:}}
{{=BEAUTIFY(response._vars.values()[0])}} {{ # To bypass the silly
colon }}
{{else:}}
{{=BEAUTIFY(response._vars)}}
{{pass}}
The point here is such pattern suits a typical controller action like
this:
def index():
form = SQLFORM(...)
if form.accepts(...):
blah_blah
return { '' : form }
therefore I do NOT need to write many boring views file again and
again like this:
{{extend 'layout.html'}}
{{=form}}
I used such generic.html in all my apps for more than one year. It did
save my numerous time.
