Coffeescript error "undefined is not a function" in hubot

Question

I'm making call to my django app that returns a JSON object and I'm using the following code to do so:

robot.hear /lunch for today/i, (res) ->
    robot.http("http://my_ip_address/show")
        .header('Accept', 'application/json')
        .get() (err, res, body) ->
            data = JSON.parse body
            res.send data.food

but it returns ERROR TypeError: undefined is not a function in the console. What's wrong with this?

Answer 1

is should look like this:

module.exports= (robot) ->
  robot.hear /lunch for today/i, (msg) ->
    robot.http("http://my_ip_address/show")
      .header('Accept', 'application/json')
      .get() (err, res, body) ->
        console.log res.statusCode
        data = JSON.parse body
        msg.send data.food

I believe the reason it is failing is because you are using res in the place of msg and then res again in the context of the function .get()
