Comments

Overview

Comments support voting, ranking, threading, images, URL previews, mentions and notifications.

Adding Comments

// Adding a comment to an activity
let comment = try await feed.addComment(

Reading Comments

You’ll also want to show/return these comments. The most important is when reading the feed.

try await feed.getOrCreate()
print(feed.state.activities[0].comments)
// or
let activity = client.activity(
    for: "activity_123",
    in: FeedId(group: "user", id: "john")
)
try await activity.get()
print(activity.state.comments)

feed.getOrCreate()
feed.state.activities.collect { it.first().comments }
// or
val activity = client.activity(
    activityId = "activity_123",
    fid = FeedId(group = "user", id = "john")
)
activity.get()
activity.state.comments

await feed.getOrCreate();

const activity = feed.state.getLatestValue().activities?.[0]!;
// Supported values for sort: first, last, top, controversial, best
// Loads the activity comments (first or next page) and stores them in feed state
await feed.loadNextPageActivityComments(activity, { sort: 'best' });

// To read comments without storing them in feed state
const response = client.getComments({
  object_type: "activity",
  object_id: "123",
  limit: 10,
  sort: "best",
});

await feed.getOrCreate();
print(feed.state.activities[0].comments);
// or
final activity = client.activity(
  fid: const FeedId(group: 'user', id: 'john'),
  activityId: 'activity_123',
);
await activity.get();
print(activity.state.comments);

const response = feed.getOrCreate({
  user_id: "<user id>",
});

console.log(response.activities[0].comments);

// Or using the getComments endpoint
const comments = await client.feeds.getComments({
  object_type: "activity",
  object_id: "123",
  limit: 10,
  sort: "best",
});

feed := client.Feeds().Feed("user", "john")
feedResponse, err := feed.GetOrCreate(context.Background(), &getstream.GetOrCreateFeedRequest{
  UserID: getstream.PtrTo("john"),
})
if err != nil {
  log.Fatal(err)
}

// Access comments from the first activity
activity := feedResponse.Data.Activities[0]
comments := activity.Comments

// Or using the getComments endpoint
commentsResponse, err := client.Feeds().GetComments(context.Background(), &getstream.GetCommentsRequest{
  ObjectType: "activity",
  ObjectID:   "123",
  Limit:      getstream.PtrTo(10),
  Sort:       getstream.PtrTo("best"),
})
if err != nil {
  log.Fatal(err)
}

commentsFromEndpoint := commentsResponse.Data.Comments

DeleteCommentRequest deleteRequest = DeleteCommentRequest.builder().build();
DeleteCommentResponse response =
    feeds.deleteComment(commentId, deleteRequest).execute().getData();

$response = $this->feedsV3Client->deleteComment($commentId, false); // soft delete

var response = await _feedsV3Client.DeleteCommentAsync(
    commentId,
    new { user_id = _testUserId }
);

response = self.client.feeds.delete_comment(
    comment_id, hard_delete=False
)  # soft delete

Querying Comments

You can also query the comments so you can show all comments for a given activity or user:

// Search in comment texts
let list1 = client.commentList(
    for: .init(
        filter: .query(.commentText, "oat")
    )
)
let comments1 = try await list1.get()

// Comments from an user
let list2 = client.commentList(
    for: .init(
        filter: .equal(.userId, "jane")
    )
)
let comments2 = try await list2.get()

// Search in comment texts
val list1 = client.commentList(
    query = CommentsQuery(
        filter = Filters.query("comment_text", "oat")
    )
)
val comments1: Result<List<CommentData>> = list1.get()

// Comments from a user
val list2 = client.commentList(
    query = CommentsQuery(
        filter = Filters.equal("user_id", "jane")
    )
)
val comments2: Result<List<CommentData>> = list2.get()

// Search in comment texts
await client.queryComments({
  filter: { comment_text: { $q: "oat" } },
});

// Comments of a user
await client.queryComments({
  filter: {
    user_id: jane.id,
  },
  limit: 20,
});

// Search in comment texts
final list1 = client.commentList(
  const CommentsQuery(
    filter: Filter.query(CommentsFilterField.commentText, 'oat'),
  ),
);
final comments1 = await list1.get();

// Comments from an user
final list2 = client.commentList(
  const CommentsQuery(
    filter: Filter.equal(CommentsFilterField.userId, 'jane'),
  ),
);
final comments2 = await list2.get();

// Search in comment texts
await client.feeds.queryComments({
  filter: { comment_text: { $q: "oat" } },
});

// Comments of a user
await client.feeds.queryComments({
  filter: {
    user_id: jane.id,
  },
  limit: 20,
});

// Search in comment texts
_, err = client.Feeds().QueryComments(context.Background(), &getstream.QueryCommentsRequest{

    "user_id": "jane",
  },
  Limit: getstream.PtrTo(20),
})
if err != nil {
  log.Printf("Error querying user comments: %v", err)
}

Map<String, Object> filter = new HashMap<>();
filter.put("object_id", activityId);

QueryCommentsRequest queryRequest =
    QueryCommentsRequest.builder().filter(filter).limit(10).build();

QueryCommentsResponse response = feeds.queryComments(queryRequest).execute().getData();

$response = $this->feedsV3Client->queryComments(
    new GeneratedModels\QueryCommentsRequest(
        filter: (object)['object_id' => $activityId],
        limit: 10
    )
);

var response = await _feedsV3Client.QueryCommentsAsync(
    new QueryCommentsRequest
    {
        Filter = new Dictionary<string, object> { ["object_id"] = activityId },
        Limit = 10
    }
);

response = self.client.feeds.query_comments(
    filter={"object_id": activity_id}, limit=10
)
