Passing parameters in rails redirect_to

Passing Parameters in redirect_to in Rails: A Complete Guide 👨‍💻

Passing parameters in redirect_to can seem tricky at first, but fear not! 🙅‍♂️ In this blog post, we will walk you through the common issues and specific problems, and provide you with easy solutions. So buckle up and let's dive right in! 💪

The Basics 📚

When using redirect_to in Rails, you can pass parameters in the URL itself or through the query string. Let's start with the URL parameters. 🌐

To pass parameters using the URL itself, you can use the following syntax:

redirect_to controller: 'products', action: 'show', id: 1

In this example, we are redirecting to the show action in the products controller with an id parameter set to 1. Easy peasy, right? 😎

Adding Form Data 📝

Now, what if you want to pass additional parameters, like form data, along with the URL? Here comes the 🔑 to unlock this problem: the query string.

To pass form data or any other additional parameters, you can append them to the redirect URL using the query string. Here's an example:

redirect_to controller: 'products', action: 'show', id: 1, category: 'tech', price: 99.99

In this updated example, we have added two additional parameters: category set to 'tech' and price set to 99.99. Feel free to add as many parameters as you need! 🎉

The Beauty of Rails ✨

One awesome thing about Rails is that it takes care of converting the parameters to a valid URL for you. Bye bye, manual URL encoding! 👋

Syntax Update ✅

Important Note: If you are using Ruby 2 or a newer version, there is a slight syntax change you need to be aware of. Instead of using =>, you should use : to define the key-value pairs. An example using the updated syntax:

redirect_to action: 'show', id: 1, category: 'tech', price: 99.99

Keep this in mind if you are working with a more recent version of Ruby. 😉
