submit.coffee

Codes you should look at:

Just some simple module require!

users = require "../lib/users"

Over here we try to make the call to the createOrUpdateUser() function with the raw data from the POST request. If there is an error, we'll need to return the error to the client side.

Note that we are returning different formats of result based on the call type. If it's a XHR request (req.xhr) then we will return a JSON style result with the res.send call. If not, we're returning a normal HTTP page, which we create through a res.render call.

module.exports = (req, res, next) ->
  
  error = ""

  users.createOrUpdateUser req.body, (err) ->
    if err
      if req.xhr 
        res.send 400, 
          meta: 
            status: 400
            msg: err
      else
        res.render "index",
          title: "Oops!"
          error: err
    else
      if req.xhr
        res.send 200,
          meta:
            status: 200
            msg: "ok"
      else
        res.render "complete",
          title: "Hello #{req.body.name}!"
          error: ""
          user: req.body
