Missing helper: "foreach" after adding custom tag page

akoznov · November 25, 2020, 8:13am

Hello!

I am trying to add a custom tags page to Ghost blog using this instruction: https://blog.many-monkeys.com/adding-a-tags-page-to-ghost-blog/

After adding page-tags.hbs, tag-card.hbs and restarting Ghost I’ve got only message in browser:

# Oops, seems there is an error in the error template.

Encountered the error:

[error.hbs] Missing helper: "foreach"

whilst trying to render an error page for the error:

undefined

[error.hbs] Missing helper: "foreach"

Hi,
I hope I can help you. Can you show me your page-tags.hbs code so I can check the code.

It may have some coding mistakes. Let me check.

Thanks

Hello Enamul,
I’m using alto theme from Ghost repo.
Here is page-tags.hbs:

{{!< default}}
{{!-- The tag above means - insert everything in this file into the {body} of the default.hbs template --}}

{{!-- The big featured header, it uses blog cover image as a BG if available --}}
{{#post}}
<header class="site-header outer {{#if feature_image}}" style="background-image: url({{feature_image}}){{else}}no-cover{{/if}}">
    <div class="inner">
        {{> "site-nav"}}
        <div class="site-header-content">
            <h1 class="site-title">{{title}}</h1>
        </div>
    </div>
</header>

{{!-- The main content area --}}
<main id="site-main" class="site-main outer">
    <style scoped>
    .inner-page-tags {
        margin-top: inherit;
    }

    @media (min-width: 900px) {
      .inner-page-tags {
        margin-top: -8vw;
      }
    }
    </style>
    <div class="inner inner-page-tags">
        <div class="post-feed">
            {{#get 'tags' limit='all' include='count.posts' order='count.posts desc'}}
            {{#foreach tags}}
                {{!-- The tag below includes the markup for each tag - partials/tag-card.hbs --}}
                {{> "tag-card"}}
            {{/foreach}}
            {{/get}}
        </div>
    </div>
</main>
{{/post}}

This is the error that matters, it’s the first one shown in the logs:

Do you have the file partials/site-nav.hbs in your theme?

akoznov · November 25, 2020, 2:35pm

No, there is no site-nav.hbs in theme. There is only files in folder partilas in theme alto:
root@vmadmin:/var/www/ghost/content/themes/Alto-master/partials$ ls
author.hbs featured.hbs header.hbs loop.hbs pagination.hbs post-header.hbs post-navigation.hbs share.hbs
comment.hbs footer.hbs logo.hbs navigation.hbs post-footer.hbs post-media.hbs related.hbs

akoznov · November 25, 2020, 2:42pm

I will try to replace site-nav to navigation and restart Ghost. Will provide feedback after that.

akoznov · November 25, 2020, 3:06pm

Changed, the site started, but Tags pages have a strange view:

Will try to make some experiments with settings in page-tags.hbs …

Hello!

I’ve made some changes on site and moved to scheme with custom-tags.hbs :

{{!< default}}

<div class="content-area">
    <main class="site-main">
        {{#get 'tags' limit='all' include='count.posts' order='count.posts desc'}}
            {{#foreach tags}}
                {{!-- The tag below includes the markup for each tag - partials/tag-card.hbs --}}
                {{> "tag-card"}}
            {{/foreach}}
        {{/get}}
    </main>
</div>

tag-card.hbs contains:

<article class="post-card {{post_class}}{{#unless feature_image}} no-image{{/unless}}">
    {{#if feature_image}}
        <a class="post-card-image-link" href="{{url}}">
            <div class="post-card-image" style="background-image: url({{feature_image}})"></div>
        </a>
    {{/if}}

<div class="post-card-content">
    <a class="post-card-content-link" href="{{url}}">
            <header class="post-card-header">
                <h2 class="post-card-title">{{name}}</h2>
            </header>
            <section class="post-card-excerpt">
                <p>{{description}}</p>
                <p>A collection of {{plural count.posts empty='posts' singular='% post' plural='% posts'}}</p>
            </section>
    </a>
</div>

Now page is showing, but there is no images in card of tag:

Maybe someone can tell me what I’m missing?

Tamer_Salama · February 1, 2021, 1:42am

I found that the issue was related to the ‘site-nav’ (partial?)

Removing the whole header block (below) worked fine for my theme

<header class="site-header">
  <div class="outer site-nav-main">
    <div class="inner">
      {{> "site-nav"}}
    </div>
  </div>
</header>
