In the views, all strings are automatically escaped (unless wrapped in XML()).
web2py HTML helpers are not escaped. However, the above concatenates a T()
object with a helper -- the result of that concatenation is actually a
string (i.e., the concatenation causes the A() helper to be serialized to a
string before being added to "Aggregator for"). If you want to combine
multiple items and still keep them wrapped in a helper so they are not
serialized to a string, but you don't want a surrounding HTML tag, you can
use the CAT() helper:
response.title = CAT(T('Aggregator for'), A('Company', _href=
'http://company.org/'))
Below, you can see that this results in a helper object, not a string, so
it won't be escaped when inserted in the view:
>>> CAT(T('Aggregator for'), A('Company', _href='http://company.org/'))
<gluon.html.CAT object at 0x3356050>
And here's what you get when the view serializes the CAT() helper (notice
no surrounding tag):
>>> CAT(T('Aggregator for'), A('Company', _href='http://company.org/')).xml
()
'Aggregator for<a href="http://company.org/";>Company</a>'
