Why does a Python Django developer need to know SQL?

Question

SQL

Why does a Python Django developer need to know the SQL language if Django itself can translate python into sql?
I understand that the question is probably stupid, but I'm just learning, but there's no one to ask, she didn't find a clear answer in Google

Answer 1

1. To write efficient queries that fit well on indexes and execute quickly
2. To avoid stupid mistakes when writing a query that is fundamentally impossible to turn into SQL
3. To avoid ORM pitfalls such as N+1 and (xs as it is called - when ORM unloads all data from the database, and then processes them on the application side)
4. In order not to generate security holes.
5. To write queries without ORM - sometimes it's faster to go to datagrip and enter the query there than to write a one-time script.
ORM, IMHO, is only needed to speed up writing queries and abstract from the syntax of a particular DBMS, but not to replace SQL

Answer 2

For general development. For the same reason, for example, it is desirable for a cultured person to know the trigonometry and valency of hydrogen.

Answer 3

Who said what is needed? If you don't want to, don't teach.

Answer 4
