Rails: Check output of path helper from console

Digging into Rails: Check output of path helper from console 🚀

Are you a Rails developer struggling to keep track of what URL a certain helper function will generate? 🤔 Don't worry, we've got you covered! 😎 In this blog post, we'll explore a common question asked by Rails developers: "Is it possible to see what URL is generated by a named route helper using the Ruby console?"

Understanding the challenge 💡

Rails provides us with magical named routes that generate helper methods for our routes. While these helpers make our lives easier, things can get a bit confusing when dealing with nested routes. It's important to know what URL a particular helper method will generate. For instance, when using the post_path(post) helper, we'd like to see the resulting URL.

The Solution: Console to the rescue! 🦸‍♂️

Thankfully, Rails allows us to easily check the output of a path helper directly from the console. 🚀 Here's how you can do it:

1. Start by opening your Rails application's console by running rails console in your terminal.

2. Next, let's assume you have a post with an ID of 1. To see the generated URL for the post_path helper, enter the following command in the console:

app.post_path(1)

1. Press enter! Voilà! 🎉 The console will display the exact URL that the post_path helper would generate based on the provided arguments.

An Example to illustrate 🌟

Let's take a practical example to solidify our understanding. Imagine we have a blog application with nested routes for posts and comments. We want to check the URL generated by the post_comment_path helper. Here's how we can do it:

1. Open your Rails console.

2. Suppose you have a comment with an ID of 5 belonging to a post with an ID of 10. To see the URL generated by the post_comment_path helper, use the following command:

app.post_comment_path(10, 5)

1. Hit enter, and just like magic, the URL will be displayed in the console. 🪄
