Akeneo category tree UI locale override

I have an Akeneo 2.3 running with 10 locales. 1 of the locales is our customised one called ab_AB.

When viewing the category tree in Settings -> Categories UI or when assigning product to categories UI, the category's label is displayed according to the locale of the logged-in user.

I would like to display the category's label value from ab_AB locale instead of the logged-in user's locale.

I have looked into /vendor/akeneo/pim-community-dev/src/Pim/Bundle/EnrichBundle/Resources/views/CategoryTree for hints of what to extend/override but not quite sure what to make of it.

Solution

To sum up what happens: the tree is generated by calling CategoryTreeController::childrenAction. The rendered twig view will format the categories using the Twig function children_response, defined in the CategoryExtension.

To set your own locale, you need to override this extension in your project (extend the class and redefine the class parameter pim_enrich.twig.category_extension.class) and override the protected method getLabel as follows:

protected function getLabel(
    CategoryInterface $category,
    $withCount = false,
    $includeSub = false,
    $relatedEntity = 'product'
) {
    $category->setLocale('ab_AB');

    return parent::getLabel($category, $withCount, $includeSub, $relatedEntity);
}

I successfully tested it with locale fr_FR while my PIM was in English. Category labels were then in French, both in the Settings → Categories menu and the category filter of the product grid.
