how to sort by lastmod?

[sudoexec]

I want to sort posts by lastmod. So I modify layouts/index.html to:

{{ define "main" }}
    {{ $pages := where .Site.RegularPages "Type" "in" .Site.Params.mainSections }}
    {{ $notHidden := where .Site.RegularPages "Params.hidden" "!=" true }}
    {{ $filtered := ($pages | intersect $notHidden).ByLastmod.Reverse }}
    <pre>{{ jsonify (dict "indent" "  ") $filtered }}</pre>
    {{ $pag := .Paginate ($filtered) }}

    <section class="article-list">
        {{ range $index, $element := $pag.Pages }}
            {{ partial "article-list/default" . }}
        {{ end }}
    </section>

    {{- partial "pagination.html" . -}}
    {{- partial "footer/footer" . -}}
{{ end }}

{{ define "right-sidebar" }}
    {{ partial "sidebar/right.html" (dict "Context" . "Scope" "homepage") }}
{{ end }}

But it doesn't work.
<pre>{{ jsonify (dict "indent" " ") $filtered }}</pre> show the sorting is like expected, but after pagination, the sorting is crashed.

Anyone know what's wrong with than? Thanks.

{{ define "main" }}
    {{ $pages := where .Site.RegularPages "Type" "in" .Site.Params.mainSections }}
    {{ $notHidden := where .Site.RegularPages "Params.hidden" "!=" true }}
-   {{ $filtered := ($pages | intersect $notHidden).ByLastmod.Reverse }}
+   {{ $filtered := ($pages | intersect $notHidden) }}
-   <pre>{{ jsonify (dict "indent" "  ") $filtered }}</pre>
    {{ $pag := .Paginate ($filtered) }}

    <section class="article-list">
-       {{ range $index, $element := $pag.Pages }}
+       {{ range $index, $element := $pag.Pages.ByLastmod.Reverse }}
            {{ partial "article-list/default" . }}
        {{ end }}
    </section>

    {{- partial "pagination.html" . -}}
    {{- partial "footer/footer" . -}}
{{ end }}

{{ define "right-sidebar" }}
    {{ partial "sidebar/right.html" (dict "Context" . "Scope" "homepage") }}
{{ end }}

@rmdhnreza Thanks for your reply! But it doesn't work. It only sorts per page but not all.

You're on the right path, but the file you're modifying is not the correct one. In order to display page x in the title, the initial .paginator was created in partials/data/title.html.

Thanks for your help! It worked.
