What is Tagging in Ruby on Rails?
Ruby on Rails’ tagging is a flexible feature that lets you link keywords or labels to different types of data, like products, blog posts, or articles. This enables efficient organization, categorization, and search functionality within your application.

Senior Level Ruby on Rails Interview Questions
Here is a list of a few senior level Ruby coding interview questions and answers. We hope this list of Ruby on Rails interview questions will help you get the job at the company you want. Let’s begin!.
Answer. A great many Rails apps use Strong Params or Strong Parameters that help make the data that is sent through forms safer. This feature facilitates developers in deciding which parameters are accepted and then used in the controller.
Only the expected params are allowed and any potentially hazardous or superfluous params are filtered out. This feature comes in handy when the developer is using Active Model bulk assignments.
Answer. When an object is created in Rails, a callback method can be called at certain points in its life cycle. These moments include events like creation, deletion, updation, or validation of an object.
Even though Rails Observers are a lot like Callback, they are used when the method is not directly connected to the object lifecycle. These tend to live longer and can be attached or detached as per the requirement.
Answer. Garbage collection has an integral role to play in ROR.
- It makes it easier to get rid of the pointer values that are left over when the program is done running.
- It gets rid of objects that can’t be reached from memory, which makes room for other processes.
- It frees the programmer from having to keep track of the object that is being created dynamically at runtime.
Answer. Both Redirect and Render are methods. The first one sends an error message if the page can’t be found or isn’t sent to the browser. It sends a message to the browser to process the case and issue a new request. The latter is used for making the content. This method works best when the controller and the variables are set up properly.
Answer. Associations are used to create a connection between different models in an application. The three main types of associations are –.
- One-to-one: one object is linked to just one other object
- One-to-many: where one object needs to be able to connect to many other objects
- many-to-many: where a lot of one kind of objects can connect to a lot of another kind of objects
Answer. There are quite a lot of aspects on which Ruby on Rails differs from Python. Here they are –.
- Popularity: Python is more well-known than Ruby. more new programmers are inclined towards Python.
- Community: Python has a bigger community.
- Website Builders: Python is a programming language, and ROR is a website builder.
- Learning Curve: It takes a little longer to learn Ruby than Python.
- Use: ROR is better at making web apps that work, unlike other frameworks. Python is better for apps in the academic research or scientific field, on the other hand.
- Applications: Ruby is better for making apps that will handle a lot of traffic.
- Ruby only supports single inheritance, but Python can handle multiple inheritance.
Answer. In fact, Ruby is a very flexible language because users can change any part of it as they see fit. Ruby has done a good job at ensuring it does not restrict the coder. Any essential Ruby’s part can be redefined or even removed as per the user’s will.
Answer. Some key features of Ruby are –
- Object-oriented: In Ruby, every value is an object with a class and a super-class.
- Flexible: It’s easy for the coder to add, remove, or change parts that are already there.
- Dynamic Typing: Ruby programs are not compiled. Instead, the coder builds all of the method, module, and class definitions when it is run.
- Case Sensitive: Capital and small letters are clearly different from each other.
- Statement Separators: A semicolon is used to split up several statements on the same line. It’s not necessary to use it at the end of the line, though.
Answer. In Ruby, a class library is made up of many domains, such as different domains, data types, thread programming, and so on. Over a higher level of abstraction, these classes provide coders with the tools they need to make powerful scripts that can be used in a variety of problem areas. Domains with relevant class libraries include –.
- Network programming
- Text processing
- GUI programming
- CGI programming
Answer. Text and string fields both hold information that can be freely written in. The major difference between String and Text lies in how many characters can be put in each.
The character limit of a string field is 255. Thus, it is best suited for storing data like name, address, etc.
The character limit of a text field is 30,000. Thus, it is best suited for storing data such as a comment box on a form.
