The first one is, I was going to publish a talk, and then I added the pictures in the order of 123, but after I published, the order of the pictures changed to 231 or 132 or 321 (the order is messed up anyway), please tell me How to solve this problem.
The second one is that I need to create a like and comment effect. The database has been built, but the back-end API and front-end have no ideas yet, and I don’t know how to start.

Now that the database is built, how can we still have no ideas?
Isn’t your database built according to the logic you need?
I always think that we should first think about how to implement this function, and then build the database according to the functions that need to be implemented.
