Showing Subcategories on the Mainpage with 0.9.3

Technical Support
  • S

    Hello everyone,

    I modified the Persona Theme so that Subcategories are shown on the Mainpage and not only on the Category-Page. That worked well so far in 0.8.3; I just modified the templates/categories.tpl by adding basically this:

    [...]
    <!-- BEGIN categories -->
    <!-- IMPORT partials/categories/item.tpl -->
    <!-- IF categories.children.length -->
    <!-- BEGIN children -->
    // HTML Representation of a Subcategory
    <!-- END children -->
    <!-- ENDIF categories.children.length -->
    <!-- END categories -->
    [...]

    That gave me a Overview like this:

    After upgrading to 0.9.3, I dont get this to work anymore. If I use my old code above, NodeBB logs following Stacktrace:

    error: RangeError: Maximum call stack size exceeded

    and restarts everytime he tries to load the theme, so nodebb is only working if I switch themes. I'm running NodeJs 4.2.3 (with 0.10 it didnt work either and the error was undefined undefined).

    I played around a bit and found out that it dies when I try to call <!-- BEGIN children -->. I also tried to call <!-- BEGIN categories.children --> (wont work) and tried to move the inclusion to templates/partials/categories/item.tpl as

    <!-- IF ../children -->
    <!-- BEGIN children -->

    <!-- END children -->
    <!-- ENDIF ../children -->

    This gives me the same Exception with a slightly different stacktrace

    Has anyone an idea why this isn't working anymore/where my mistake is? What is causing this error? I would really like my subcategories back at my mainpage.

    Thanks for your help!

    @Saari templates.js had a bug. update templates.js to v0.3.2

    npm i [email protected]

    you will have to update package.json and change templates.js version to 0.3.2 otherwise NodeBB won't start/restart

    after the upgrade try this...

    <!-- BEGIN categories -->
	<!-- IMPORT partials/categories/item.tpl -->
		<!-- BEGIN children -->
			//your subcategory code... use categories.children.key syntax here
		<!-- END children -->
	<!-- END categories -->

    you don't have to check for children length... <!-- BEGIN children --> won't do anything if children is empty

    Just to butt in here, is this the same method this forum (NodeBB) uses to add sub categories to the categories listing, or is it done another way?

    @charles thank you! It's not showing up as requiring an update in the ACP, hence my confusion. It is on NPM though, i'll pull it from there.

    Only option is to pull from git. When will it be available on ACP?

    @Danny-McWilliams You will need the master branch of NodeBB or latest from v1.x.x branch for that to work.

    Thanks @pichalite I'm currently on v1.0.0. It'd be nice to have, but I think I should just get my forum online again before looking at cosmetic alterations!
