Custom Object__Feed

Represents the feed, specifically posts and feed-tracked changes, on a custom object.

A custom object feed shows posts and changes to the object’s tracked fields. The object name is variable and uses Custom Object__Feed syntax, where Custom Object is the name of the custom object. For example, Textile__Feed represents a feed on the custom object Textile__c.

Supported Calls

delete(), describeSObjects(), getDeleted(), getUpdated(), query(), retrieve()

Special Access Rules

In the internal org, users can delete all feed items they created. This rule varies in communities where threaded discussions and delete-blocking are enabled. Community members can delete all feed items they created, provided the feed items don’t have content nested under them—like a comment, answer, or reply. Where the feed item has nested content, only feed moderators and users with the Modify All Data permission can delete threads.

To delete feed items they didn’t create, users must have one of these permissions:
  • Modify All Data
  • Modify All on the parent object, like Textile__c.
  • Moderate Chatter

    Users with the Moderate Chatter permission can delete only the feed items and comments they can see.

    Note

    Only users with this permission can delete items in unlisted groups.

Fields

Field Details
BestCommentId
Type
reference
Properties
Filter, Group, Nillable, Sort
Description
The ID of the comment marked as best answer on a question post. This field is available in API version 44.0 and later.
Body
Type
textarea
Properties
Nillable, Sort
Description
The body of the post. Required when Type is TextPost. Optional when Type is ContentPost or LinkPost.
CommentCount
Type
int
Properties
Filter, Group, Sort
Description
The number of comments associated with this feed item.

In a feed that supports pre-moderation, CommentCount isn’t updated until a comment is published. For example, say that you comment on a post that already has one published comment and your comment triggers moderation. Now there are two comments on the post, but the count says there's only one. In a moderated feed, comments aren’t counted until approved by an admin or someone with Can Approve Feed Post and Comment or Modify All Data.

Feed moderation has implications on how you retrieve feed comments. In a moderated feed, rather than retrieving comments by looping through CommentCount, go through pagination until the end of comments is returned.

Description
Indicates whether the feed item Body contains rich text. Set IsRichText to true if you post a rich text feed item via SOAP API. Otherwise, the post is rendered as plain text.

Rich text supports the following HTML tags:

  • <p>

    Though the <br> tag isn’t supported, you can use <p>&nbsp;</p> to create lines.

    Tip

  • <a>
  • <b>
  • <code>
  • <i>
  • <u>
  • <s>
  • <ul>
  • <ol>
  • <li>
  • <img>

    The <img> tag is accessible only via the API and must reference files in Salesforce similar to this example: <img src="sfdc://069B0000000omjh"></img>

In API version 35.0 and later, the system replaces special characters in rich text with escaped HTML. In API version 34.0 and prior, all rich text appears as a plain-text representation.

Usage

A feed for a custom object is automatically created when a user enables feed tracking for the custom object. Use feeds to track changes to the custom objects they serve. For example, Textile__Feed tracks changes to a Textile__c object. Use feed objects to retrieve the content of feed fields, such as type of feed or feed ID.

Note the following SOQL restrictions. No SOQL limit if logged-in user has View All Data permission. If not, specify a LIMIT clause of 1,000 records or fewer. SOQL ORDER BY on fields using relationships is not available. Use ORDER BY on fields on the root object in the SOQL query.
