About About Hi there! So you are just starting with Rails? That's great! And then this place is for you. It summarizes some of the most important information about Ruby on Rails for your reference.

Now we should be able to see what we got so far.
If everything went well, you should see the Rails signature welcome page. Layout Time to code. Where should we start? Well, we can start wherever we want to.
When I build a new website, I like to start by creating some kind of basic visual structure and then build everything else around that. In order to do that, generate a new controller called Pages.
If you are not familiar with Rails controllers, you should skim through the Action Controller to get an idea what the Rails controller is. Run this line in your command prompt to generate a new controller.
The output in the command prompt should look something like this: We are going to use this PagesController to manage our special and static pages. Now open the Collabfield project in a text editor. I use Sublime Text , but you can use whatever you want to. Of course we could define home page in a different controller and in different ways. But usually I like to define the home page inside the PagesController. All our controllers, which we will create, are going to inherit from ApplicationController class.
Which means that all methods defined inside this class are going to be available across all our controllers. Open a routes. Insert this line: Your routes. Just write something inside the file, so we could see the rendered template in the browser. Now we have a very basic starting point. We can start introducing new things to our website.
Add all current changes by running: git add -A Then commit all changes by running: git commit -m "Generate PagesController. In order to use this library we have to install the bootstrap-sass gem. Open the Gemfile in your editor.
As the documentation says, you have to ensure that sass-rails gem is present too. Save the file and run this to install newly added gems: bundle install If you are still running the application, restart the Rails server to make sure that new gems are available. Go to assets to open the application. This is necessary in order to use Bootstrap library in Rails, also it allows us to use Sass features. We want to control the order in which all. The one we'll focus on is PDFKit.
PDFKit gives us a great balance between control and ease of use. You can follow along with the video in the associated Invoicer example application. Foundations To start, we'll quickly review the foundation of this app based on its models and relationships. The job of this application is to produce sales receipts. If we navigate to the root URL, we see that we have an index of invoices and a show page for each invoice already built out.
It's pretty traditional invoice behavior with a very simple data model.
Its job is to allow us to render our PDF template from our Download object. Last updated on Get this book by renowned teacher and author Daniel Kehoe. No other tutorial does a better job of explaining the concepts. Master the basics.
