[web2py] pass a arbitrary html attributes with helpers (bootstrap data-toggle with A() for example)

[Richard]

Hello,

I would generate programmatically a bunch of links with A() helper from controller, but I fall on syntax error because of data-toggle custom bootstrap attribute (new with html5). 

Ex.: UL([ LI(A(l.upper(), _href='#tab1', _data-toggle='tab')) for l in list_of_letters_required ], _class='nav nav-tabs')

Can I pass a arbitrary argument with helpers or should I alter the helper??

Also, since this new html5 feature mean a lot of new attribute all the time what's the plan about that, we can stay behind waiting for new _Attribute get implement all the time...

Thanks.

Please put the attribute with the hyphen in a dictionary:

UL([ LI(A(l.upper(), _href='#tab1', **{'_data-toggle':'tab'})) for l in list_of_letters_required ], _class='nav nav-tabs')

From web2py book http://web2py.com/books/default/chapter/29/5#HTML-helpers:

 

Instead of a set of unnamed arguments, a helper can also take a single list or tuple as its set of components using the * notation and it can take a single dictionary as its set of attributes using the **

UL([ LI(A(l.upper(), _href='#tab'+str(i), **{'_data-toggle':'tab'})) for i, l in enumerate(list_of_letters_required) ], _class='nav nav-tabs')

Only one pairs of curly brackets and the attribute needs to be quoted since it is a key dict finally...

Thanks!
