Missing foreign key on subform record

[Costa]

Good morning everyone.
I have a problem with a subform because the two files of the form and the subform are regularly transcribed to the database but the foreign key field does not show the ID of the form record but rather the word "autoid".
If I manually modify this field by inserting the relevant form record number, I am shown the form and subform with all the data.
The nubuilder log reports no errors. I'm working with Maria Db 10 and PHP 7.4.

Thanks for any help you can give me.

Hi,

Could you show a screenshot of your subform settings and the db schema of the subform table?

Hi kev1n,

First of all thanks for your replay.
Here the Db subforn table structure:

As you can see from the second record, the last field shows "autoid" while in the previous record I modified it by inserting the value "14" to see if the foreign key worked.

The settings of the subform object are in the attached screenshots.

Thanks for the help to understand...

Could this be the problem?

viewtopic.php?p=29521#p29521

[Costa]

Yes, it seems like it is.
I hadn't previously tried to retype the subform data once the form had been saved but having done so I see that the two files are linked via foreign key. I noticed from the post you suggested the solution to insert the string

Code: Select all

if(nuIsNewRecord()){nuActionSave();
}

but I didn't understand where.
Thanks for your help

[kev1n]

This would go in the form's Custom Code (Edit Form)

[Costa]

I thought it should be put there but it doesn't work for me, same problem

[kev1n]

I haven't suggested/tested this workaround and suggest you use nuBuilder's UID primary key instead of an auto increment when dealing with subforms.

[Costa]

I reworked the database to use the nuBuilder uUID primary key and now everything seems to work.
Thanks for your time spent helping me
