"@claudiomg would you be so kind to tell me where did you find the "custom code" part?" Check the image below
"I understand the code can be changed manually and it gets overwritten when doing a Publish... and i know you can exclude a file to be re-generated... but then the code will not be updated if you change something in the GUI editor is not that right?" Yes, you are right. If you uncheck a file, this file will not be re-generated. If you need to update the GUI in the editor, you will need to change the file manually. Because of that, I suggest that you use the custom code field. This way, you don't need to uncheck the file. The file will be always regenerated and your modifications in the custom code field will be preserved.
"Is there any way of adding some INCLUDE/REQUIRE statement in the GUI so the file can be regenerated and you can keep your code?" I don't know if it is possible to do that.
I was able to create a new button without the need to change the view. I just copy the 'delete' button code and use its code on with a field, I was able to use the code in the 'CustomCode' property
But I need to create a special function in the page's controller. I just use one of the functions that are already created, then I copy and modify the code to fit my needs. Every time I made a change, the project is published, my special function controller is overwritten (erased it), but after that, I find out that is possible to uncheck the controller in the Publish option, this way the controller code is not overwritten anymore.
@claudiomg please check the where the window and you will see a sample code at the top, double-clicking and it will be added to the text area, you can then edit it the way you want to use it.
I want to create a sql query using the USER_ID (Active User ID that is logged in)
Check the image below
I write the number 2, but I want to use the USER_ID, if I change the number 2 to USER_ID or $USER_ID, the query fails, how can I use correctly the USER_ID in a query?
