Developing an application with Ruby On Rails is easy, but it would be even easier to use if you follow these simple yet effective tips and tricks. Note this! These 5 useful Ruby On Rails tips and tricks will have you wild in no time!
- Don’t overload the view with logic
By embedding ruby in HTML, ERB allows you to create your views. However, it would be best to be very careful when building your views, as large files are difficult to maintain. There is also a risk of code repetition in this area, which sometimes leads to violations such as DRY. For determinate logic, hire a ruby on rails developer.
Use helpers in views whenever you feel the same code is repeated often, use layouts and partials when the same code is repeated often in views, and use presenters/decorators like Draper to reduce lines of code in your views.
- Avoid too much logic in the controller
MVC is at the heart of Rails. To increase code testability and readability, maintain a lean controller. Sign up for Ruby On Rails online training for a free live demo and learn more about Ruby. In the controller method, always use the second approach when dealing with database queries. The controller has many logics, but these are the best practices we can use.
- Session and cookie management
- Find the right database model for a given operation
- Render result based on request type such as HTML, XML, JSON, etc.
- The logic for collecting parameters and performing operations is based on these parameters.
- Monitor Application Exceptions
This is typical of exceptions, and when they happen, you should be aware of them! Customers don’t have to let you know that a problem has occurred; you should already know this and work on solving it. Rails have exception notifications since 2005. It is possible to receive exception notifications with plugins. Still, some services, like Airbrake Bug Tracker and Get Exceptional, add value to your app.
Exceptions are centrally managed, so you can see how often they occur, in what environment they occur (a specific browser? a certain location?), and what settings were present. By centralizing data, you can see patterns and fix issues faster, which results in a better app and happier users.
- Avoid overly complex logic
The primary responsibility of an Active Record model does not include functions such as generating email notifications or interacting with external services. The main functionality of Active Record is to perform CRUD operations in databases.
In Model, one of the best logics is:
- Relationships (associations) between records
- Update attributes in a database and save them.
- Access wrappers that hide internal model information (for example, full_name methods that combine first and last name in the database).
- Do not use Active Record queries outside of the model.
- With a Ruby On Rails course, you can reach new heights
MVC is all about using as little logic as possible. We could stop at this point and think, where else can we apply all our logic? Did he say anything in Rails about logic? Of course not! However, using logic in MVC is not recommended. Alternatively, all the logic can be placed outside the MVC, which won’t slow down the application, and we can manage it more easily.
- Watch out for gems
It would be great if you always remembered that each gem depends on the others. The size of your Rails application increases when you use a large number of gems. Performance in production environments may suffer. Server memory configuration may also increase. When adding gems to your app, be careful and cross-check.
