I Fixed a Silent Bug in an Open Source Project - Here's What I Learned

The bug looked small. An email input in a footer. But it was completely broken. I was exploring the wagtail/news-template codebase as part of my Google Summer of Code (GSoC) application. I found the newsletter signup in the footer. You could type your email. You could click "Sign up". Nothing happened. Why it broke The "Sign up" button was an <a> tag. It linked to an external URL. It had no connection to the input field. The input also had no name attribute. In HTML, form fields without a name are never submitted. Even if a form existed, the value would be lost. The fix I wrapped the input and button in a <form> element. I set the action to the external signup URL. I used method="get" so the email becomes part of the URL as a query parameter. I also added name="email" and required to the input. <form action= "{{ signup_url }}" method= "get" > <input type= "email" name= "email" required placeholder= "Enter your email" > <button type= "submit" > Sign up </button> </form> Three lines chan
