What are some effective debugging tips for Ruby on Rails?

Here are some effective debugging tips for Ruby on Rails:

1. Use the built-in debugger by adding binding.pry in your code.
2. Check the Rails logs for error messages and stack traces.
3. Utilize the rails console to test code snippets in real-time.
4. Use byebug for step-by-step debugging.
5. Write tests to catch bugs early.

Can you explain how to use binding.pry?

Sure! To use binding.pry, first, you need to add the pry gem to your Gemfile. Then, insert binding.pry in your code where you want to pause execution. When the code runs, it will stop at that line, allowing you to inspect variables and execute Ruby commands in the console.

What should I do if I encounter a 500 error?

A 500 error indicates a server issue. Check your Rails logs for detailed error messages. Look for stack traces that can point you to the source of the problem. Common causes include syntax errors, missing files, or issues with database connections.

Are there any tools that can help with debugging?

Yes, there are several tools that can help with debugging in Ruby on Rails, such as:

• Pry: for interactive debugging.
• Byebug: for step-through debugging.
• Better Errors: for enhanced error pages with stack traces.
