Switch between 2 or more templates with an action in controllers?

Question

I have a default Phoenix application. This app will have a page_controller which will load an index.html.eex file.

The app will know to use the view to access templates/page/index.html.eex.

Now say you have created another html page which is identical to index.html.eex in every way except it is in French.

As we do not want to create a whole new Phoenix application which will have all the same code, with the exception being the French translation of the current page/index.html.eex, is there a way to tell the view or the controller which file needs to be loaded.

Is there a plug which can be placed in the router to alter where render will look for it's templates?

Answer 1

First of all I would suggest you to use Gettext to use labels for French pages.

For example you can all French templates keep in the very same folders (to don't change logic for view), but to name them with suffix eg. "index_fr.html.eex" etc. and then you can write quite simple helper (not necessarily a plug) that will add to all of your templates this suffix.

Still, I would recommend you using Gettext - template's source code is only in place and almost all of the logic Gettext handles for you.
