Switch select box parameter using radio button.

[Florent Barra]

Hello, 

I'm trying to display a select box depending on the option chosen (2 options with 2 select box, if we select option 1 we display the first select box).

I'm trying to do this choice using radio button or html link but in both case, it doesn't work.

here my code :

#---------------------------------------------------------------------------------------------------------------------------

from __future__ import with_statement

from nagare import editor, presentation, component, validator

class Option:

def __init__(self):

self.option2 = 'opt1'

self.option_result = ''

class OptionEditor(editor.Editor):

def __init__(self, option):

self.list1 = ['a', 'b', 'c']

self.list2 = ['1', '2', '3']

self.option = 'opt1'

super(OptionEditor, self).__init__(option, ('option_result', 'option2'))

def test(self, opt):

self.option = opt

def commit(self):

super(OptionEditor, self).commit(('option_result'))

@presentation.render_for(OptionEditor)

def render(self, h, comp, *args):

with h.form:

h << 'option1 '  << h.input(type='radio', name='option').action(self.test('opt1')).selected(self.option == 'opt1') << h.br #<< h.a('X').action(self.test('opt1')) << h.br

h << 'option2 '  << h.input(type='radio', name='option').action(self.test('opt2')).selected(self.option == 'opt2') << h.br #<< h.a('X').action(self.test('opt2')) << h.br

with h.select(multiple='multiple').action(self.option_result):

if self.option == 'opt1':

with h.optgroup(label='Option 1'):

for i in self.list1 :

h << h.option(i, value=i).selected(self.option_result())

else :

with h.optgroup(label='Option 2'):

for i in self.list2 :

h << h.option(i, value=i).selected(self.option_result())

return h.root

class App:

    def __init__(self):

        self.option = Option()

        editor = OptionEditor(self.option)

        self.editor_component = component.Component(editor)

@presentation.render_for(App)

def render(self, h, *args):

h << self.editor_component

return h.root

app = App

#---------------------------------------------------------------------------------------------------------------------------

Despite the choice made, 'option' is always equal to 'opt2', and i don't understand why.

Hi Florent,

Here you're always  calling `self.test('op1')` and then `self.test('opt2')` when the view is rendered. That's why `option` is set to 'opt2'. What you want instead is to register callbacks because you want `self.test('op1')` or `self.test('op2')` to be called later, when the user will submit the form. So, just change your actions registration code by `...action(lambda: self.test('op1'))` and `...action(lambda: self.test('opt2')`
