[web2py] Re: string not recognized

[Anthony]

You could also define the string in the controller and pass it to the view:

def action():
    return dict(mystring=PRE('{{this is a string}}'))

View:
{{=mystring}}

Or if you need to do this frequently in views, you could define a special 
helper:

class BRACE(DIV):
    def xml(self):        
        return '{{' + self._xml()[1] + '}}'

{{=BRACE('this is a string'}}

will output:

{{this is a string}}
