Yii2 converts the ID query of some fields into names in the columns of the DynaGrid plug-in, causing the query statement to be executed multiple times.
Yii2 converts the ID query of some fields into names in the columns of the DynaGrid plug-in, causing the query statement to be executed multiple times.
][1]
As shown in the picture above, if written like this, the query statement in value will be executed multiple times, resulting in slower access speed.
What should be done to solve this problem?
That’s what I think, but I don’t know if it’s right.
1. I directly group all the required data in the controller and then transfer it to DynaGrid for output, but this will involve related queries of multiple tables. There may be 6 or 7 tables. Will it cause access speed problems? ? Besides this method, is there any better solution?
2. When doing step 1, there are some fields that are not in the table, such as "company id". How can I transfer them to DynaGrid for output?

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
