Your Perfect Guide to Integrate Bootstrap 4 with Rails 5

When it comes to web development, bootstrap is one of the most recommended frameworks to be used since it brings a lot of advantages that cannot be found from another framework. Bootstrap is now making a big impact on web developers and it is now unstoppable. There are a lot of reasons why people should use bootstrap for web development.

Reasons why Bootstrap is Used

Developers are using bootstrap because development can be done real quickly. Applications and websites are easily done because codes are already provided which makes it easier and you can modify it according to your needs. Also, bootstrap is being used because it is responsive because it can be done in any devices with different screen sizes.

In addition, customization is also one of the reasons why people tend to use bootstrap as their framework for web development. You can choose your preferred needs and features and you will be given your desired bootstrap that you can use for your web development.

These are just some of the reasons why people mostly choose bootstrap as their framework when web development is the concern.

On the other hand, bootstrap will not only give you the websites that you have always desired to produce but its bootstrap 4 can be integrated with rails 5.

How to Integrate Bootstrap 4 with Rails 5

If you want to know how to make the integration between the Bootstrap 4 with Rails 5 possible, here are the guides to follow which will help you achieve it successfully.

  • Include the bootstrap gem to the Gemfile.
  • Guarantee that the sprockets-rails are v2.3.2.
  • Then, bundle install and start the server again for the files be accessible in the pipeline.
  • After that, you can import the bootstrap styles in the app/assets/stylesheets/application.sccs. Remember, the variables must have an extension such as .sass or .scss.
  • Once you have imported the styles, you can now eliminate the *=require and *=require_tree that are found on the files with Sass extension.
  • After eliminating, you can now use the @import in order for you to import the Sass file.
  • When you have a Sass file, do not utilize the *=require because you may not be able to have an entry on the variables of Bootstrap.
  • Then, you can now have the bootstrap JavaScript.
  • If you want to have a quick compilation, it is best to use the concatenated bootstrap.
  • Then, add the tether to the gemfile that you have.
  • After you have entered everything, you can now run the bundle and start the server, and necessitate the tether just before the bootstrap.

Following these guides, you will be able to integrate the bootstrap 4 with rails 5 successfully. Doing so, you will be able to find a big difference between the two and will not give you any problem when you are integrating the bootstrap 4 with rails 5 since all the needed codes are provided and the only thing you have to do is to enter the right code to let the result happen.

 

How to set up a simple Rails development environment with Docker

When setting up is the concern, nothing is easy especially if the one that you will have to setup is framework filled with codes. Docker is a container that is known to be an application and packed with dependencies which will be running in the host operating system. Docker can run in a variety of infrastructures like Microsoft Windows, Linux distros and Mac OS. The container is packed with runtime, codes, libraries, and system tools that can be easily installed on computers and will run no matter what platform is used.

Docker is now being used to rails development environment. When your rails do not use any container, the tendency would be is that the development may be difficult due to the needed specifications of the platform used.  However, if you make your rails application Dockerized, there is a big tendency that the inconsistencies will be eliminated because the application is being packed together with Docker’s dependencies and configurations. Because of this, programmers are having lighter jobs since the tools needed for applications are complete.

What do you need?

In order for you to set up a simple rail development environment with the help of Docker, prerequisites are present which will help you achieve the impossible. The things that you need are of course the Docker toolbox and the docker-sync.

How to setup?

  • The first thing that you need to do is make a Dockerfile which will serve as the starting point in the myapp-dev-box- which is empty.
  • Then, dependencies will now be installed which will be used for the web application. The dependencies will only run by a sole command because the Docker can easily catch the condition of a container. It is best if you re-run the whole step and you must include the apt-get update which will guarantee that the dependencies are up to date.
  • After, you can now make a folder where you can keep the SSH keys and the app. SSH keys should be present since it is the one that will point out the private sources that will be used in the bundle install.
  • Then, let the bundle install run.
  • Use the Docker toolbox which has the docker-compose that will help in establishing and will be associated with the containers for the app run.
  • Once everything is done, you can now use the docker-sync which will sync the bundle and files for a web project. When syncing, always keep in mind that per project synced, it has its own unique ports.

Now, the setup is complete and you are able to create a rail development environment with the help of Docker.

If you want your rails applications run on different platforms or even be free from inconsistencies, using the Docker is the best option. It is the best option that you can find if you are up for a simple rail development environment since the setup is not difficult and can be done easily if you have the proper tools needed.

How to achieve parallelism with Ruby MRI with I/O bound threads

Language is not only used by people but even websites are using it. The language is one of the main problems that programmers are facing especially when Ruby’s is the matter. The performance that Ruby’s gives can be one of the reasons why programmers would not want to use the language. Because of the complaints about the performance about Ruby’s, it only shows that the framework is getting behind from other frameworks that are used by programmers today. Even though those issues have happened because of Ruby’s, it is easy to use.

The question will always be, how can you reach parallelism with Ruby’s?

To answer, the best solution is to have the 1/0 bound threads. The threads can influence the parallelism that is seen in the processors today. The Ruby MRI is known to be a non-supporter of parallelism. Even though you have lots of threads, with Ruby MRI, only one thread will continuously run and it is because of GIL.

There are statements found that Ruby MRI will not help in reaching parallelism and it is all because of GIL, that is responsible for imposing restrictions on threads. Because of this, people think the Ruby is useless and is a not a good help in reaching parallelism. These statements may be true enough if you are using the CPU-bound operations. Why? When you use the CPU-bound operations, a great performance will never be evident and will always have low performance and it is all because the thread scheduling is handled by the user space and GIL plays a big role since it is the one that limits the threads.

In contrary to these statements, the I/O bound threads are the ones that help in letting Ruby MRI reach parallelism. The I/O bound threads’ speed is limited by the I/O found in computers. The one that handles the I/O bound threads is the Ruby interpreter which is found in the kernel space. Because the Ruby interpreter is located externally, the I/O bound threads can run freely since restrictions are not present and will be able to run in parallel because the GIL is not present. The kernel space is the one responsible for scheduling the I/O bound threads which will let them run continuously on numerous hubs.

If you want your threads to run and reach parallelism without any restrictions, the Ruby MRI with I/O bound threads is the best option. Unlike using the CPU-bound operations, you can likely encounter a lot of restrictions in your thread because GIL is present. No matter how a great number of threads that you, if the GIL exists, only one thread can run simultaneously. Nevertheless, if you use the Ruby MRI with I/O bound threads, your performance can improve and will definitely reach parallelism. Also, if you are working on an I/O bound task, the Ruby MRI with I/O bound threads is the for you because it can run in parallelism and will not stop you from having multiple threads.  Just remember that your threads should be safe at all times.

A Guide on Converting a Hash to a Struct in Ruby

Before we get deeper in to the conversion process, let us all first identify the difference between the two – the hash and the struct. This will let us help answer the question why some prefer using the struct than hash in Ruby.
Differentiating Hash from Struct

Hash is the collection of the key-value pairs and it’s the same to the Array, except the fact that the indexing was made through the arbitrary keys of any types of objects (not the integer index). An order in which are traversing a hash by value or key may seem arbitrary – and generally may not be in the intersection order. On the other hand, struct is the more convenient type of way to bundle the numbers of attributes together. This is by the access methods without needing to write explicit classes.

Struct will allow an instance to be generated with set of accessors and this looks powerful and convenient for the user. Even though hash can do similar thing, it is coup with some pitfalls, which you may don’t like. Struct is easier to understand, which will lead the users to a more maintainable coding. Furthermore, it is worth noting that struct outperforms hash when it comes data retrieval speed, which will let you know that struct can be a better choice compared to the hash for the configuration needing to be accessed in a repeated manner at the runtime.

Converting Hash to Struct in Ruby

With the fact we know about the two, many will perhaps prefer using struct rather than hash. But what we want to focus here is that behind the low performance given by hash, they still can become advantageous. If you can’t use it on its own little way, then convert it into struct so better usability can be achieved.
If you have already defined the struct and you wanted to initiate converting hash to struct, we can help you by using the following methods in a given example below. If you wanted to convert has to a struct in Ruby, let us say for example we have a given of:

h = { :a => 1, :b => 2 }
and want to have a struct such as:
s.a == 1
s.b == 2
To convert, you can do any of these methods:
Conversion Method 1:
On this method, the result will appear to be OpenStruct and not specifically as struct:
pry(main)> require ‘ostruct’
pry(main)> s = OpenStruct.new(h)
=> #
pry(main)> puts s.a, s.b
1
2

Conversion Method 2:
If you have struct defined already and want to start something with a hash, you can follow this:
Person = Struct.new(:first_name, :last_name, :age)

person_hash = { first_name: “Foo”, last_name: “Bar”, age: 29 }

person = Person.new(*person_hash.values_at(*Person.members))

=> #

Conversion Method 3:
Since the hash key order was guaranteed in the Ruby 1.9+, you can follow this:
s = Struct.new(*(k = h.keys)).new(*h.values_at(*k))

The hash to struct conversion example we provided can help, but if you want a more extensive idea, come to professionals for formal assistance.
