Hi everyone…

Thanks for letting me joining this forum…

I’ve bought grocery crud enterprise, and for basic needs, it suits me well and help me alot. Problem arise when i want to use some custom query and use set model. Despite of the table show up sucessfully, the search and the pagination didnt work. it only show 10, 20 or 50 first data (depend on the setting per page). I am using the code example as show on github here

i am inserting code that i use here…i am appreciate for the help… and sorry for my bad english.

Hello @sam210388 and welcome to our forums :hugs: ,

You are right! There was an issue at the documentation for the limitation that I’ve never thought about. I’ve updated also the documentation for customModel. Below you can find the diff that I’ve updated so it can also include the limitation bug that you are referring to.
