i18n in deformdemo dysfunctional

[Hans-Peter Jansen]

Hi,

I've used a good part of the day for getting i18n fixed in deformdemo,
but failed so far. :(

While all debug instrumentation show green lights, the translation
strings aren't picked up for some reason:

I've uploaded it here: https://github.com/frispete/deformdemo

Could somebody more familiar with the pyramid translation machinery be
so kind to have a look into this?

Thanks in advance,
Pete

The issue is *usually* that the TranslationString instance hasn't been run through `request.localizer.translate(..)`. Now, why not? I haven't dug in to try and figure that out yet.

I noticed that the renderer is not being used. The `deform.Form.set_default_renderer(render)` is commented out. Uncommenting it doesn't solve the problem but it's definitely an issue as the zpt_renderer isn't actually being used as a result.

I got the renderer working via the following diff. Unfortunately the translator is still not invoked which leads me to believe that there is something wrong with the i18n tags in the chameleon templates, but I don't know enough about chameleon to dive in there. Hopefully this was helpful though.

Hi Michael,

I will look into this right now.

Thanks for your care. Much appreciated.

Cheers,
Pete

Thank you for that.

 

I found the culprit! The call to:

 

deform.renderer.configure_zpt_renderer()

 

intercepts the translation handling by replacing the carefully constructed

zpt_renderer with a default one, that omits any translators.

 

Hrmpf. I'm preparing fixes for deformdemo at the moment, and will report this

issue to the deform project.

 

While at it, what is the purpose of these hidden schema nodes:

 

_LOCALE_ = colander.SchemaNode(

colander.String(),

widget=deform.widget.HiddenWidget(),

default=locale_name)

 

Cheers,

Pete
