How to add or remove discussion/post properties

dotronglong

I want to modify some fields/properties of discussion/post before rendering (JSON) to the response. I tried to look inside the code, however, I don't see any possible event to do that. Is there anyone already encountered this problem before, I am appreciated if you could share your solution.

Additionally, I looked into these methods:

flarum/core/src/Api/Controller/ShowDiscussionController.php#data
flarum/core/src/Forum/Content/Discussion.php#__invoke

dotronglong You can do this by listening to the Serializing event through the Flarum root extend.php (same folder as config.php) or through an extension (still listening to that event).

To use this event, you'll have to check for the serializer. See the second codeblock under the Relationships heading @ https://flarum.org/docs/extend/data.html#serializers for an example.
