Sidebar with Custom Template Tags - Building a web app with Django - Part 17

[@ajudmeister]

🐞Bug Alert!! The first Comment for a Post doesn't show up!! - In Part 12 I implemented an if statement to hide the tabs on the Post page: kzbin.info/www/bejne/imatl5WVgdCijJIsi=nJfUCHD-hekaBpr2&t=1118 - this does not work together with htmx! I give an explanation and solution here: kzbin.info/www/bejne/onTdqqKefquobKcsi=BJL604HbNfUSpMIE&t=1835.

loved your content. as a django developer i really hate switching to frontend framework. this seemed to be the perfect solution. keep this coming. love from nepal

[@ajudmeister]

Thanks a lot! Yea Django gives you already such a good frontend system with the templates, and if you use htmx you don't need to add an additional highly complex framework on top of it anymore to achieve interactivity.

You are amazing mate

[@TomislavMiletic]

This approach is great, but can you please explain how does it differ from using context_processors?

[@ajudmeister]

To be honest I haven't worked with context processors yet, but both of those approaches work. Template tags are specific to a template, so in my case I want to show the sidebar only with one specific layout (the a layout), in this case template tags work better in my opinion. Context processors attach data to all the requests, so it's available globally. They make sense when this data is used across multiple templates and views. They also require adding additional settings to the settings.py file, which I want to avoid in order to keep the file focused on the most critical configurations.

Hi, I love your work here. Can you tell me how you can limit number of posts/comments displayed in the sidebar?

[@ajudmeister]

Hi, just add [:5] to the end of query if you want to display just 5 posts. Full line: top_posts = Post.objects.annotate(num_likes=Count('likes')).filter(num_likes__gt=0).order_by('-num_likes')[:5]

Hey Andreas. I got a question. We made a rule that no authorized users can not comment, right? So there is no need to put in top comments a new if to write no author, isn't there?

[@ajudmeister]

That's right you need to be authenticated to comment, but I put it in for the case that the author deletes his account, in this case the comment will not be delete because in our Comment Model we have on_delete=models.SET_NULL on the author property. So the comment will have no author assigned to it.

[@icezzzWZ]

Perfect! You'd thought in all details. Thanks for the explanation.@@ajudmeister
