Disable Rails SQL logging in console

How to Disable Rails SQL Logging in Console 🚫💾

Are you tired of scrolling through pages of SQL query logs when trying to debug in the Rails console? Look no further! In this post, we'll explore an easy solution to disable SQL query logging so you can focus on what really matters - your debugging process. Let's dive right in! 🏊‍♂️🔍

The Problem at Hand 🤔❓

Have you ever found yourself in this situation? You're working in the Rails console, trying to debug an issue, and all you see are endless lines of SQL queries mixed with your "puts" output. It's like finding a needle in a haystack! 😫

The Ideal Solution 💡✨

The ideal solution would be to have a simple command to disable and re-enable SQL query logging directly in the console. This would allow you to focus on your debugging process without being distracted by the noisy SQL logs. 🎯🙌

The Solution 👌🔧

After some digging, I've found two reliable solutions to disable SQL logging in the Rails console. Let's check them out! 🕵️‍♀️💡

Solution 1: Setting the Logger to Nil 🙅‍♂️📜

One way to turn off SQL query logging is by setting the logger to nil. It's as simple as a one-liner in your console. Just execute the following command:

ActiveRecord::Base.logger = nil

Voila! 🎉 SQL query logging is now disabled, and you can focus on your debugging process. However, please note that this solution might raise an error if something other than your code tries to call logger.warn.

Edit:

I have found another solution that tackles the error mentioned earlier. Instead of setting the logger to nil, simply set the logger level to 1 (or Logger::INFO). This is achieved by running:

ActiveRecord::Base.logger.level = 1

This will effectively disable SQL query logging while ensuring the logger remains functional for other purposes. 🙌✨

Solution 2: Using the Rails Database URL 🔌🔗

Alternatively, you can disable SQL query logging through your Rails database URL. This method involves appending ?pool=0 to your URL. Here's an example:

DATABASE_URL="postgres://localhost/my_database?pool=0"

Keep in mind that this solution disables pooling, which may have performance implications. Therefore, it is recommended to use this solution only in development or when debugging specific issues.
