Hello Tom,

I am looking at this page for a refresher

http://apostrophenow.org/tutorials/snippets/advanced-server-side-1.html

This is my module in app.js

’supper-map':{
  extend: 'apostrophe-snippets',
  name: ‘supperMap',
  label: 'Maps',
  instance: ‘supperMap',
  instanceLabel: 'Maps',
  menuName:’superMapMenu’
}

This is my index.js

module.exports = superMap;

function superMap(options, callback) {
  return new superMap.Map(options, callback);
}

superMap.Map = function(options, callback) {
  var self = this;

  module.exports.Super.call(this, options, null);


  if (callback) {
    process.nextTick(function() {
      return callback(null);
    });
  }

};

I get the following error

/usr/src/app/lib/modules/supper-map/index.js:10

  module.exports.Super.call(this, options, null);

                      ^

TypeError: Cannot read property 'call' of undefined

Any ideas?

PS - To be honest I wanted to override the apostrophe-map module, but since I can’t get it to work I fell back to the documentation, and I see that the problem is the same when trying to override a snippet.

Hello Again,

Ok, I figured out that I was not using the “plural” instance name in my factory constructor and this seems to make a difference.

So this works

module.exports = superMaps;

function superMaps(options, callback) {
  return new superMaps.SuperMap(options, callback);
}

superMaps.SuperMap = function(options, callback) {

  var self = this;

  module.exports.Super.call(this, options, null);


  if (callback) {
    process.nextTick(function() {
      return callback(null);
    });
  }

};

Can this be possible?

There's a lot of inconsistency (supper vs. super, singular vs. plural, name and instance the same?) in what you've sent here. I think you have some things to iron out there.

Hello Tom,

I really made an effort of forking the boilerplate to replicate the problem. The spellings mistakes you see here is because I didn’t copy paste the code, but rather overrode the names given that my client name was used as a prefix.

Anywho…

For anyone ever stumbling here, the actual problem was the fact ( and I am very ashamed of this ) that I hadn’t installed ‘apostrophe-snippets’. I know … I know…

It is something I noticed I was doing instinctively trying to replicate the error, to show you, and that is how I noticed.

So, make sure you have in your package.json the module you are trying to extend.

Cheers,

FP
