Coffeescript + Express.js : cannot call method 'sliced' of undefined

Question

I'm making my first app in express.js and coffeescript. The code is at: https://github.com/findjashua/contactlist

When I try to run it, I get the following error:

/Users/jashua/local/lib/node_modules/coffee-script/lib/coffee-script/helpers.js:216
  codeLine = codeLine.slice(0, start) + colorize(codeLine.slice(start, end
                      ^
TypeError: Cannot call method 'slice' of undefined

I'm assuming it's something to do with contacts.coffee, but can't think of anything. Any ideas?

Answer 1

You never close the parens for new ContactModel( .

  exports.addContact = (req, res) ->
contact = new ContactModel(
    name: req.body.name
    phone: req.body.phone
contact.save((err) ->
    if not err
        console.log('created')
        res.send(contact)
    else
        res.send(error)
)

My tip: forget all these parens. Part of the nice thing about coffeescript is you can use indentation and not have big chains of floating closing delimiters like the close parens in your source. Just do:

someFunction (arg1, arg2) ->
  body of nested function
