Why is a substring added when setting the url from the template?

Question

Django

Greetings. It has this url:

path('author_topik&<int:author_id>', author_topik.author_topikDef, name = 'ved_author_topikDef'),

, respectively, when forming a link of the type in the template, "{% url 'ved_author_topikDef' 2 %}"I can expect that a link will be formed: ... author_topik&2, but it happens that ... author_topik&2. I draw attention to amp;.
Please tell me why and how to work with it.

Answer 1

Because "&" is split for "URL parameters" and django expects path to be just "URL path".
