If you are actively using Rails for developing your projects, then it’s likely that in at least one of your projects you are using PostgreSQL as the database technology. You have already added the pg in your Gemfile and have already started to use it. Then your client asks you about the version of PostgreSQL that you are using, and you may be confused for a bit about it, as you aren’t sure.

ActiveAdmin gem is really helpful, as it gives you the opportunity to get admin dashboards in just a few minutes, without having to do everything manually on your own.

You will most probably need to have at least one particular case where you need to store configuration values for your Rails application. Saving these types of values in the environment is one of the principles of a twelve-factor app. It is thus recommended to use a separate file and use environment variables inside your code so that you do not have to change the same value in multiple places. This, however, is not something that you can do really easily unless you use something really helpful like dotenv.
If you are sometimes feeling bored and want to entertain yourself, then rather than aimlessly scrolling in a social media, you can try to learn something new.

You do not want to even think about the possibility for a data loss of the project that you are working it. Luckily, there is a really beneficial feature that is not that much known from Rails developers is a quick tool that you can use to test out some code without changing any data in your real database.
It is really hard to think about a real world project in which you are not going to have strings. As a result, having pre-existing methods for manipulating strings is really productive, as it saves you time. In today’s article, I want to emphasize a particular method in Ruby on Rails, that’s surprisingly not that much well known, which helps you with the whitespaces. Continue reading

There are many programming languages and frameworks out there, which are prepared to be used to solve problems.

This way, we have design patterns that are abstractions of some of the best ways to deal with certain situations. Continue reading

You may need attributes in your views or in your JSON response which may not be part of your models. In these situations, you may use virtual attributes that you may only use in your particular cases, and not bother to add many new attributes in your database table that are not that much relevant for that model.
