[LRUG] [JOBS] Help with AngularJS + Rails

[Stephen Masters]

Agustin,

I just wanted to say well done on including services in your example as an equivalent to Rails models. I find it a much better way of thinking of them compared to pretty much every other explanation of AngularJS services out there.

I have spent quite a bit of time over the past week or so going through online AngularJS materials, and pretty much everything (including the main tutorial) seems to treat services as an afterthought. The Green & Seshadri book from O’Reilly is a particularly bad example of this. I would have experienced far less pain if those materials had shown the use of services early on.

I’m guessing that it’s easier in tiny demo examples to just dump everything inside a controller, as it involves less code, but an application doesn’t need to be big at all (mine is currently barely 200 lines of JavaScript) before it will benefit from refactoring large chunks out into one or more services. The trouble is that because there are so many examples of using controllers to store models and view state in $scope, noobs such as myself assume that it’s the "AngularJS Way” of doing things. And looking at StackOverflow questions and apps linked from angularjs.org, that can to lead to some unfortunate design decisions, such as storing variables in $rootScope in order to make them available across multiple controllers.

So thank you again for attempting to demonstrate a well structured AngularJS application, rather than showing how awesome interactivity can be implemented on a web page with 10 lines of code or less. :)

Cheers,

Steve

In this case my approach is try to avoid massive changes in my rails code and do ir all I can to divide my Rails app and my AngularJS app.
