Django

Django, templatetags, python

I share my implementation of built-in tags to form breadcrumbs with support for schema.org markup, as well as support for bootstrap css.

Wrote these tags to speed up site development speed. Now the work moves much faster, because the code has become more compact, and correcting errors in the breadcrumbs markup has become much easier, since now you only need to correct the code in one place.

Django

templatetags, template, Django

In Django - Lesson 035. Different templates for rendering different types of content in search results it was shown how to render different templates depending on what type of content drawn in the search results on the site. In this case, the key point was that it was not necessary to make the verification conditions for the selection of the template. The information about the balbalon was stored in the variable TEMPLATE_PREVIEW, through which the template was inserted into the include tag in the Django template.

{% include object.TEMPLATE_PREVIEW %}

In this method there is one big drawback. The fact is that the include tag with each of its calls is looking for a template. With a large load on the site - this can significantly increase the duration of the response from the server. To solve this problem, you need to somehow cache the pattern. Since different types of content use different templates, to do this using inclusion_tag is quite problematic.

This problem was solved by caching the template at the class level as a class variable.

Django

Django, templatetags, Python, список популярных статей

The site already had an article about the withdrawal the list of popular articles in the last 7 days . But in the variant that is used in this article shows how to draw a conclusion on the Articles page. But there was a question as to quickly implement a list of popular articles on any page of the site.

I have solved this problem by using its own tag , which can be used in a Django template. That is, instead of each View on the site to register the same code to obtain a list articles or the use of the same function in this View, I just did a single template with a finished layout for a list of popular articles, which uses my custom tag, which I take a list of these articles. Thus, you only need to implement this pattern in the right place in the page template using the include tag.
