从特定的Chatter组将帖子（海报名称，照片，正文）获取到VF页面-努力进入VF

Question

I am working off of some code I found on the Internet - I have only been on the ADM 201 course.

What I am doing is attempting to pull the information from a post and then put this into a VF page. I know I can use chatter:feed, but this is getting all of the information and functions, whereas I need only the text body, poster name, and picture (not essential).

What I have so far:

Apex Class:

    public class Test_3 {        //Class is 
public ConnectApi.FeedElementPage feedElementPage{get;set;}
public Test_3() {
    feedElementPage =    ConnectApi.ChatterFeeds.getFeedElementsFromFeed('0F958000000TWvL',   ConnectApi.FeedType.Record, 'showInternalOnly');
    }
    }

VF page:

<apex:page controller="Test_5">
   <div class="posts">
      <div class="row">
      <div class="col-md-6">
        <apex:repeat value="{!feed.elements}" var="feedElement">
            <div class="media">
                <a class="pull-left" href="{!feedElement.parent.id}">
                <img class="media-object" src="{!feedElement.photoUrl}" alt="{!feedElement.actor.name}"/>
                    </a>
                    <div class="media-body">
                        <h4 class="media-heading">{!feedItem.actor.name}</h4>
                        // This creates a heading from the posts that is the poster's name
                        {!feedElement.body.text}
                        // This is the body of the post
                        </div>
                    </div>
       </apex:repeat>
      </div>
 </div>
</div>

Current issues:

• !feedElement.parent.id
• !feedItem.actor.name
• "Error: Unknown property 'ConnectApi.Feed.elements'"

Anyway, I can't work this out. I've been trying to make this for a lovely 5 hours now.

Any help would be much appreciated.

The code was modified from here and then I attempted to update it to Elements from Items.

Thanks

In your Apex class, the variable is called "feedElementPage" but in the Visualforce page, it says "feed". Please update feedElementPage to feed in Apex class or update repeat value="{!feed.elements}" to repeat value="{!feedElementPage.elements}"

In addition, I think you should use FeedItem instead of FeedElement . Please take a look at the document, and let me know if you have any other questions.
