Just skip the bits in
http://rtfm.modx.com/display/revolution20/Creating+a+Blog+in+MODx+Revolution that you’re not going to use (comments, sections, archives - not sure if you’re going to use tags or not?).
1. Create a BlogPost template (you don’t strictly even need this if you’re not using any of the blog extras), but you might as well. Using the template in the tutorial, strip out anything you’re not using in the class=post-info paragraph tag, and remove the postmeta and post-comments class divs entirely.
2. Create a document under your news folder using that template
3. Create a blogPost chunk (a mini-template) that you want to use on the News index page - a really stripped down version of the one in the tutorial:
<div class="post">
<h2 class="title"><a href="[[~[[+id]]]]">[[+pagetitle]]</a></h2>
<p class="post-info">Posted by [[+createdby:userinfo=`fullname`]]
</p>
<div class="entry">
<p>[[+introtext]]</p>
</div>
<p class="postmeta">
<span class="links">
<a href="[[~[[+id]]]]" class="readmore">Read more</a> | <span class="date">[[+publishedon:strtotime:date=`%b %d, %Y`]]</span>
</span>
</p>
</div>
4. In your News resource (which uses your normal or default template), first make sure that the Rich Text toggle is OFF (at the bottom). Then put this in the Content:
[[!getResourcesTag?
&element=`getResources`
&elementClass=`modSnippet`
&tpl=`blogPost`
&pageVarKey=`page`
&parents=`[[*id]]`
&includeTVs=`1`
&includeContent=`1`
&limit=`10`
]]
[[!+page.nav:notempty=`
<div class="paging">
<ul class="pageList">
[[!+page.nav]]
</ul>
</div>
`]]
You can get rid of the paging stuff if you want. You only need ’includeTVs’ if you are using the tags. If your client publishes a lot of news, you might want to up the &limit number - but if this happens you probably want to introduce some form of sectioning or archiving anyway.
5. And really, that should be more or less that. getResources will automatically sort by the published on field, so your client can either duplicate an existing blog/news entry or create a new one (using the BlogPost template) and publish it, and it will automatically appear in the News page - as long as she creates the news item under ’News’.
Hope this helps.
