Another NEWBIE question... I have a REST API that can update a record using PUT. The server is written in Node.JS + Express + MongoDB.
Clint side is using JQuery and EasyUI.
I am only a beginner and have just learnt that HTML forms cannot do anything but a POST or GET. Therefore how should I develop my UI for an update dialog without using a form ?
Pointers to a sample would be great...

In case there is no answer to this.. I discovered I can work around this relatively easily by simply inventing a new pat on the server that is specifically for updating the record I am interested in and using POST for that one also. That means that Create and Update record can both use POST but to different URLs.

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.
So I'm working as a software apprentice and I have to re-build a website.
Basically what the website does is: post different things (events,news,etc.) and all these posts have like a preview and then when you click on it, it takes you to the post.
The way thay it works is: in the code it has a template for the design of every post. But if you want to make a new post, you need to do it from WordPress.
So know I'm looking the way to do that, I think that the first developer used json to "call" the data from the database in WordPress (I guess).
So I hope that someone can help me with a different or a easier option to do that.
Thanks
There are various gems that integrate with the wordpress api. And you could always write your own api wrapper.

Im trying to understand the best method for creating a basic Rails app that is only interfaced with via GET values in the url. Im attempting to understand how to go about starting to write logic for this as well as generally where i would want to start coding. Would this main interface code be considered a helper? or should i migrate the code to the model?
An example of how i'd like to use this app is something like the following.
http://www.railsapp.com/?order_number=123&print_label=true
With this example url i hope to grab the order_number get some information from it, determine if print_label is true/false and output something to the user.
Im not looking for someone to write it all for me, i'm simply needing some guidance on the best structure on writing a rails app that is only interfaced with via a URL as well as the easiest method for gather GET values.
Between the 3 comments on the first post i am going to looking into Restful routing and by that gather my params to interact with them.
I´m mainly a coder but for a project I've got to do some more with RoR. I've been working with RoR for some projects but mainly on the front-end side. I understand it a basic level, but for this project I have to dive in the deep.
What I want to create is an app where a user can search for movies and add them to their account. I want to use theMovieDb api for this, but I can't find a screencast or tutorial that shows the beginning of how to connect your app with someone else's api. So I was hoping the StackOverflow people could point me in the right direction.
This is kind of a big question, but it seems you have two parts here. First is how to make a request from inside your application. The second is how to interact with an API.
I've set up somethings similar where I had to make API requests from inside a controller using Net::HTTP. The answer to this question helped a lot. From inside the controller, I processed the request response as needed, i.e. putting it into a relational database, or displaying it to the user.
How make a HTTP request using Ruby on Rails?
The second part about interacting with the database. The movie database API is described at
http://docs.themoviedb.apiary.io/reference
You need to reference this API documenation. The first thing, for instance, = is they require you to get an API key for instance. You will also need to be aware that they limit the rate at which you can make requests. Without knowing more specifics its hard to give more detail about how to construct the queries.
Hope this helps.
Basically I'm wondering if it's possible to have a form on a site outside of mail Rails app to POST to a form in my Rails app. For example (not what I'm going to be doing) a contact form on a Wordpress site, when submitted would POST the values to my Rails app. What would my steps be to make that possible? Or any references that are already out there?
OR if it's possible to load a form from my Rails to an outside site using Ajax or something. Eh that's probably a long shot but don't know what would be more secure and slim on code.
Thanks so much!
If you do it with AJAX you may have to handle XSS issues. Maybe you need to write an easy API for your application that could be consumed from that other application. That's not difficult from Rails and you can get help from some good controller abstractions like inherited_resources.
At some point that external application will send a form to itself using AJAX and will handle it and send it to your rails application using JSON or XML... or whatever format you want.
Yes, you can do it. Be aware that you'll have issues with the form authenticity token, so it might be easier to turn the token off.
