Hi Massimo and all pals,
This post is about a tiny trick. Hopefully you will like it and
include it in the next version of web2py.
I used to do this in controller:
def foo():
# do something
return dict(partA=some_words_in_a_table, partB=major_part_as_a_form)
so I need to write a foolish foo.html just to show contents BUT bypass
the display of "partA" and "partB" themselves:
{{extend 'layout.html'}}
{{= partA}}
{{= partB}}
This is boring.
Finally, I got an idea and change the generic.html in this way:
{{extend 'layout.html'}}
{{ # Bypass the _vars key name when there is only one object to be
rendered. }}
{{content = response._vars.values()[0] if len(response._vars)==1
else response._vars}}
{{=BEAUTIFY(content)}}
So, in above example, I can write the controller like:
def bar():
# do something
return dict( this_key_name_is_invisible = DIV(
some_words_in_a_table, major_part_as_a_form ) )
And I don't need the foolish foo.html anymore!
Hope the above explanation is clear and helpful to some of you. Thanks.
