Do I need separate fields in models to use iframe?

Question

Django

Need the ability to embed YouTube videos into articles on the site, do iframes need a separate field in the table? If yes, then what?

Answer 1

If your article consists of html markup (usually test editors for web forms are assembled in this format), then a separate field is not needed. It is enough to insert the collected text as normal html.
If vue is used, then it will be.
In your case, I think it would be better to use a ready-made solution for text formatting. For example https://quilljs.com/ or ckeditor which can be embedded in the django admin.
They support video display as you need out of the box.
