How do I post a message to a specific room?

[nambrot]

I want to build an anonymous messaging handler that lets you message lita which in turn will message a channel or user anonymously. It is not obvious to me how I would message that is not a direct response?

[jeremy-albinet]

You may create a fake Source. Something like :

target = Source.new(room: '#myroot')
robot.send_message(target, "Message")

[nambrot]

That's what I thought, but it didnt work for me, it just does nothing. I'm using the slack adapter.

[9] pry(#<Lita::Handlers::Anonymous>)> target = Source.new(room: '#litatest')
=> #<Lita::Source:0x007f941a8b9150 @private_message=false, @room="#litatest", @room_object=#<Lita::Room:0x007f941a8b9100 @id="#litatest", @metadata={}, @name="#litatest">, @user=nil>
[10] pry(#<Lita::Handlers::Anonymous>)> robot.send_message(target, "Message")
=> ["Message"]

Would that be an adapter problem then?

[jimmycuadra]

The value for the :room argument needs to be the room's ID. Either of these should work:

Source.new(room: Room.find_by_name('litatest').id)
Source.new(room_object: Room.find_by_name('litatest'))

Edit: See my other comment below, the second version I show here is wrong.

[nambrot]

I'm sorry if I'm missing something very obvious but neither

[12] pry(#<Lita::Handlers::Anonymous>)> target = Source.new(room: Lita::Room.find_by_name('litatest').id)
=> #<Lita::Source:0x007fb7abd6dde0
 @private_message=false,
 @room="C0FV0E1AM",
 @room_object=#<Lita::Room:0x007fb7abd6dd90 @id="C0FV0E1AM", @metadata={}, @name="C0FV0E1AM">,
 @user=nil>
[13] pry(#<Lita::Handlers::Anonymous>)> robot.send_message(target, "Message")
=> ["Message"]

nor

[14] pry(#<Lita::Handlers::Anonymous>)> target = Source.new(room_object: Lita::Room.find_by_name('litatest'))
ArgumentError: unknown keyword: room_object

In the first case, no message gets sent, in the last case, I cant seem to create the fake source

[jimmycuadra]

What version of Lita are you using?

[jimmycuadra]

Also, I'm gonna leave this issue open because this needs to be added to the documentation website. It should be easier for folks to figure out how to do this.

[jimmycuadra]

Oh, I was remembering wrong. The keyword argument to the Source constructor is just :room, but you can pass it either a string ID or a Room object.

The first example you show in Pry looks like it worked, though, no?

[nambrot]

@jimmycuadra Thanks for re-opening.

Lita version:

➜  wellframe-lita git:(master) ✗ bundle show lita
/Users/nambrot/.rvm/gems/ruby-2.2.3/gems/lita-4.6.1

The first example didn't throw any errors, but I didn't see anything get posted in the channel and I am unsure about how I would further debug it.

[nambrot]

@jimmycuadra Do you have any other ideas of what I should try?

[jimmycuadra]

Is Lita present in the room you're attempting to send the message to? I'm not sure how Slack behaves if it's not.

[nambrot]

Yes, I did invite Lita to the room

[jimmycuadra]

The code you showed in Pry where you create the source object manually looks completely correct to me. I don't have another immediate suggestion, unfortunately—this looks like it will require some interactive debugging.

[nambrot]

Do you have any idea where to put my focus on during the debugging? Somewhere in lita or somewhere in lita-slack?

[jimmycuadra]

I'd start in the Slack adapter.

[nambrot]

I figured it out. The problem was that I set a breakpoint inside the adapter, causing any issues of messages to be queued as lita-slack is using EM. I'm not sure why they wouldnt eventually bubble through, but it works now. Adding the handler was a breeze from there! https://github.com/nambrot/lita-anonymous
