I modified web2py_ajax.html (in trunk) so that it now takes a new
response.headers['web2py-component-content']
which can be 'prepend', 'append' or 'hide' and you can do
def index():
return dict(check=LOAD('default','test.load',ajax=True))
@auth.requires_login()
def test(): return "hello world"
def user():
if request.extension=='load' and not auth.user:
response.flash = 'hey! login please'
response.headers['web2py-component-content']='prepend'
return 'oops, you must login'
return dict(form=auth())
Is this acceptable?
