sub menu doesn't show localized items

[Alexander Smolensky]

I've created custom flat menu using Replacing both the FlatMenu and FlatMenuItem models

The problem is, that if menu has submenus, items there from link_page, and not from link_page_fr or so. Same is for link_text.

As a result, I have:

home_en
- page_en_one
- page_en_two

in another language I have:

home_fr
- page_en_one
- page_en_two

but I need:

home_fr
- page_fr_one
- page_fr_two

class TranslatedPageField(object):
    def __init__(self, en_field, fr_field):
        self.en_field = en_field
        self.fr_field = fr_field

    def __get__(self, instance, owner):
        active_language = translation.get_language()
        if active_language == 'fr':
            return getattr(instance, self.fr_field)
        return getattr(instance, self.en_field)

class TranslatedFlatMenuItem(AbstractFlatMenuItem):
    menu = ParentalKey(
        TranslatedFlatMenu, # we can use the model from above
        on_delete=models.CASCADE,
        related_name=settings.FLAT_MENU_ITEMS_RELATED_NAME,
    )
    link_page_fr = models.ForeignKey(
        Page,
        verbose_name=_('Link to an internal page (Frenc)'),
        blank=True,
        null=True,
        on_delete=models.CASCADE,
        related_name='link_page_ru',
    )
    link_url_fr = models.CharField(
        verbose_name=_('Link to a custom URL (French)'),
        max_length=255,
        blank=True,
        null=True,
    )
    link_text_ru = models.CharField(
        verbose_name=_("Link text (Russian)"),
        max_length=255,
        blank=True,
    )
    translated_link_text = TranslatedField('link_text', 'link_text_fr')
    translated_link_url = TranslatedField('link_url', 'link_url_fr')
    translated_link_page = TranslatedPageField('link_page', 'link_page_fr')

    def translated_page(self):
        return self.translated_link_page

    @property
    def menu_text(self):
        """Use `translated_link_text` instead of just `link_text`"""
        return self.translated_link_text or getattr(
            self.translated_link_page,
            settings.PAGE_FIELD_FOR_MENU_ITEM_TEXT,
            self.translated_link_page.title
        )

    def relative_url(self, site=None, request=None):
        if self.translated_link_page:
            try:
                page_url = self.translated_link_page.get_url(
                    request=request, current_site=site)
                return page_url + self.url_append
            except TypeError:
                return ''
        elif self.translated_link_url:
            return self.translated_link_url + self.url_append
        return self.link_url + self.url_append

Any suggestions of what kind of information I need to add? Have I missed something or did wrong?

Good day. Maybe this will help you: #242 .

@noparamos, yes, I've read that issue and some solutions, but no success with AbstractFlatMenuItem. Adding localized do nothing. It shows submenu for page in link_page but when I active another language and want to get submenu for link_page_fr I got nothing.

@AlexDeltax you will want to look at (and override) the methods on the menu model that gather the pages needed for generation, like the developer in the linked PR is doing.

It looks like you're using a completely different approach to translation than they are, so the code will not work like-for-like - you will need to figure out how to use your menu model's language-specific foreign key values.

Am closing this issue, as it isn't a bug with this software - more a support request
