In this episode, we worked on a weekly view for the Django app. We made navigation that would let users click from one week to the next, then fixed up the view to pull time from that particular week. The first thing that I did was focus on the UI required to navigate to a new weekly view in the app. We mocked out the UI and talked briefly about the flexbox layout that is available to modern browsers.

In this episode, we added content to a template and talked about the N+1 query bug. I also worked tricky logic involving date handling. The first change was to update a course page to include a new icon for any course task that should be graded. After adding this, we hit an N+1 query bug, which is a performance bug that happens when code queries a database in a loop. We talked about why this happens and how to fix it.

In this episode, we worked on an edit view. We used Django’s generic UpdateView to aid the process and test drove the creation of the view to verify things every step of the way. We worked on a view to make it possible to edit the CourseTask model that are the actions that a student must complete for a course. To complete the form quickly, I took advantage of Django’s ModelForm views.

In this episode, we worked on the template styles of a tabular view. We also made some context data adjustments to include header rows and column highlighting. I started by showing the template that I already created. It was rough. Before changing anything, I took the time to explain the modeling in use for this project and the context passed to the view. The models mostly form a tree in the a hierarchy.

In this episode, I added a CSS framework, Tailwind CSS. After working through some issues with the log out feature, we started to style the base template of the site. To stay true to my “make the minimum possible thing that will work,” I added Tailwind CSS from a CDN, content delivery network. <link href="https://unpkg.com/tailwindcss@^1.0/dist/tailwind.min.css" rel="stylesheet"> I described how Tailwind’s utility-first approach makes designing sites a breeze because of …

In the last article in the Understand Django series, we saw how a user’s browser request goes from their browser to Django’s “front door.” Now it’s time to look at how Django processes those requests. An HTTP request coming from a browser includes a URL describing which resource Django should produce. Since URLs can come in many forms, we must instruct Django on the kinds of URLs that our web application can handle.

In this episode, we added django-allauth to create accounts that default to email instead of using usernames. We added the package, configured some templates, and created tests. We continued to look at Will Vincent’s django-allauth post on creating user accounts with email and passwords. django-allauth let’s us swap out username and email so that users won’t need to create a username, which is the behavior that I want for this service.
