Here is another solution:
The following is NOT a solution for multiple reasons the main of which is that
the context is going away and soon you won't be able to use this.
The second is that IData is not for external use but rather internal Nevow
usage.
class Main(rend.Page):
addSlash = True
docFactory = loaders.xmlfile('nestedsequence.xhtml')
def data_control_list(self, ctx, data):
print "data_control_list"
return [('a', 'first'), ('b', 'second')]
def render_control(self, ctx, data):
print 'render_control'
ctx.fillSlots('ctrl_label', data[1])
ctx.fillSlots('ctrl_name', data[0])
option_list = [('1', 'uno'), ('2', 'due')]
ctx.remember(option_list, inevow.IData)
return ctx.tag
def render_option(self, ctx, data):
ctx.fillSlots('opt_label', data[1])
ctx.fillSlots('opt_value', data[0])
return ctx
The template is the same, the only change is
n:render="sequence" instead of
n:render="option_list"
in the <select> element.
However there is a thing the I don't understand:
why render_control is called two times?
In my previous solution, both render_option_list and render_control are
called two times.
I don't remember the template and thus I don't think I can be of any help here.
But this way of coding is called 'being clever' and you'll regret it when
you'll have to maintain that code or understand how the code actually works.
