Hello

I want to extend the `ChannelMessage` struct.  
How can I do this?

I searched a lot but didn’t find any solution for this. This bothered me a lot.

Thank you for helping me.

Hello @Bahman.Binary,

Can you please elaborate on what you’re trying to achieve by extending the struct?

@sesposito  
well, I want to add some props to the channel message for my own customization but I don’t know how to do this. I found out that there is some limitation in Golang struct extending and I don’t know how to get around this limitation.

The message format is defined in the server protobuf definitions.

Can you elaborate on what you’re trying to add? The message content is a json payload, you can add custom data there if needed.

Best.

I specially want to add a property named `KickerId` that actualy is `caller` variable’s UUID in function of `KickGroupUsers` of `core_group.go` file.

@sesposito Actually I want to detect who kicks another user in group.  
If you have a better idea to do this, I welcome it.

Extending the message doesn’t seem to be the best approach here, we’ve created an internal ticket to add support for the `kickerId` to be added to the content of the message in a future release.

Best.
