Maybe this is a dumb question or even a common asked question (or just a lousy searcher). I want to start a new web application project using Ruby on Rails. On the other hand, I really like Angular JS with Angular Material for the form design. The have everything already implemented like an autocomplete, different types of buttons, etc.
Now the question is, how to combine those two? I want to use Ruby on Rails's routing, controller, models, resource etc. but Angular Material more for the Frontend Design and catch user's actions in events.
You could place all of the AngularJS files in /app/assets.
Another good way is to create a repos with only the front-end part.

I'm about to start a new project and I am unsure if using AngularJS for my front end would be a good idea not. I've read about people saying this isn't the smartest way of doing a project. And even if I did, Is there a way to get AngularJS to interact with the controllers? This question may be redundant but I am actually curious of how to effectively do this without it being a waste of time.
I've never completely done it, but I believe the way to go is to build a Rails api and then have a separate Angular project use said api. The api could also be used to build a mobile app. I think the Angular project would still need to be served from a Node.js server in production, but I don't think that would be a big deal.
This is what I used to learn how to build a Rails api: http://apionrails.icalialabs.com/book/chapter_one
You can do it within an existing project and share the models from it.
There are several different approaches to accomplish that. I tried about 5 different guides out there, the best I found (and I finally sticked to) was https://thinkster.io/angular-rails - This guide should help you build a basic CRUD app with angular connected to rails.
You use Rails as an JSON RESTful API which responds to Ajax-Requests (Get, Post, Put, Delete). Angular will handle the frontend stuff - sending those Ajax requests to the routes/methods defined in your rails controllers. So yes, of course your AngularJS app can interact with your rails controllers.
This also helped me to understand the setup in the beginning: Instead of the Rails View, you will be using AngularJS as your view:
I really love using angular with rails, because setting up the JSON responses (especially with Active Model Serializer Gem) is very easy and quickly done. i deffinitely can recommend it, and I have not encountered any unsolvable problems - so far.
Just go trough this guide I linked and you will see if this setup fits your needs.
The short answer is that your Rails application will have to present some kind of a public API for your AngularJS application to consume. Angular (and it's brethren, like React and Ember) runs client-side, on the browser, and it needs "something" to make AJAX calls against. That "something", i.e. your backend, can be Firebase, Parse, AWS Lambdas, Rails API, etc. Since you already have a Rails application, it probably makes the most sense to add some RESTful API endpoints that use the existing models (and possibly controllers) to consume/produce JSON payloads from/for the client.
There are tons of tutorials out there for creating single page applications using Rails and Angular. They usually pass all the routing to Angular and leave Rails for the activerecord stuff. I find this frustrating because there are times when I just want a plain HTML page with minimal client side bells and whistles.
What is the best practice for a multi-page application, where I can use both Rails routes and Angular UI-router?
I would use the Angular router so all of your routes are in one place. The best part about angular is you can add as much or as little as you want. So you can have static pages handled by the angular router.
I have a existing project in Ruby on Rails.
What is the best way to use AngularJS in Ruby on Rails app?
I want to use AngularJs for only specified modules, not for create SPA. This is good way?
What I have seen colleagues do in order to achieve this sort of integration with an existing rails app is:
Include angular.js and relevant dependencies in the specific app pages that are to be 'angularized'
Interpolate whatever data is needed to bootstrap the angular controller into the html template which contains the angular app. This might include data about the resource being operated on. I've seen this done by rendering a RABL template inside of a haml/erb template.
Using that interpolated data, call whatever API methods you need to get additional data on the fly. This is usually just a matter of implementing json handlers for routes you've already created.
I can't say whether this is best practice, but its an easy way to get started fast.
Best of luck, angular is a very enjoyable tool to work with once you get used to it.
I need some guidance to figure out how to incorporate Angular inside rails.
Reason for choosing Rails : I like their opionated approach to do things right. Also migrations, gems are really cool.
Reason for angular : I was researching and looking for framework best suited for SPA. Backbone seem too abstract. I had choice to make between Angular & Ember. I started reading Angular first and it made sense to me. So i never went to read about ember.
Reason for Angular & Rails: I researched and tried using small scale framework like grape, slim ( Yes i use php too ). But i feel need to stick to rails for long term scope of project. And personally i like doing things rails way.
So here is where i need help,
I have rails project in Rails 4.
Sign-in , sign-up everything is created as followed in Michael Hartl tutorial. Have tweaked stuff based on my requirement.
So post-sign-in or post-sign-up steps a view from show action of users controller is rendered.
I figured i'll need different layout files so i created same for outer pages and inner pages, respectively.
I don't know how to proceed i want to make use of the angular templates and routes for my single page app ( which resides post sign-in ). I am flexible if there is another way. I just need a guide how to use angular seemlessly with rails making use of rails controller to handle my rest request and using routing provided by angular to navigate around in SPA.
Hope i am clear. Feel free to edit this.
here is a great railscasts from ryan bates: http://railscasts.com/episodes/405-angularjs
also here is the source for that railscasts you can get ideas from there:
https://github.com/railscasts/405-angularjs
I'm not familiar with SPA, but I have been working on a tutorial for integrating rails and angularjs, which I'm refining over time. It may provide some answers here - in particular I am using the angular routing to provide a single-page app as you describe: http://technpol.wordpress.com/2013/09/03/angularjs-and-rails-tutorial-index/
I would suggest you to not mix angular into your rails app. Keep both of them separate.
So you could either place the whole of your angular app in the public folder of your rails app or keep it completely away from the rails app. This is more like a service oriented architecture, where your rails app serves as a back end serving as an api and the front end(Angular app) consuming that api.
There are many many nice articles the covers how to handle the authentication/authorization
in angularjs with REST APIs.Authentication with AngularJS and a Node.js REST api
Coming to the rails side for building REST API, Grape is a nice choice. Here is a nice series explaining some best practices about grape.
HTH!
I'd suggest taking a look at this tutorial: How to Wire Up Ruby on Rails and AngularJS as a Single-Page Application. I have used it for a few personal projects, so I am sure that it is up to date as of late 2014. If you want to view it in action you can head to http://goodmatches.herokuapp.com, and you can view the repo.
Try half-pipe gem which makes using bower for managing javascripts assets much easier.
Most of the resources/example about rails and angular on the internet just put them together. AngularJS goes inside of rails under app/assets. This feels reeeaaaly dirty to me. Is it a good idea? What if we decide at some time we won't be using rails and we move to, I don't know, sinatra? How hard would it be to port?
What would be pros/cons of everthing in a single rails app and what would be pros/cons for two seperated apps?
Thank you!
Even when placing Angular (or any other client-side MV* framework) inside your Rails app, you are pretty much keeping the separation of concerns intact. That is, you have a Rails API serving JSON (or similar) data, and a separate Javascript framework using that data to render appropriate views. If you ever wanted to use a different server-side API, you can do so, and still utilize your entire Javascript directory as is.
Placing the client side framework in Rails is simply a matter of convenience. It comes with an organized directory structure and the ability to serve your HTML, which is essentially all you're using it for when it comes to your views. But again, these views aren't really tied to Rails, as they're just HTML and Javascript, so you can easily move them to a different platform when necessary.
