How to implement page creation in django admin?

Question

Django

Icons of sections will be displayed on the main page of the site: cabinets, fittings, materials, etc.
Accordingly, links will lead to pages with this content.
I want to implement the creation of such sections of the site in the admin panel.
There is a main application of the site CORE. It will have a "pages" section.
In the admin panel, you create a new one, write the title, slug (which will be the url address), description, keywords and the actual body of the page. The CORE model is given below.
I display the content of such a page in a separate template, in which the SAFE tag is specified, so that not just text is displayed, but formatted html.
Everything is fine, but tags and variables like {{ page.title }} are not displayed if they are entered in the admin panel.
What is the best way to implement the creation of pages-sections of the site through the admin panel?
After all, there should not just be html tags, but django tags to embed albums, etc.
