WIX.com Primary key to be used as reference - velo

Question

I'm new to the WIX web development platform.
I need to use the Primary Key of Table 1 to be used as a reference of Table 2, but I cannot use the ID of table 1 for this purpose.
I wonder if the best way is to "copy" this ID in the Title field (Primary Key) of this table 1. How I do that? Is this the best method?
Thank you,
Arturo

Arturo:
Have you tried doing this without using wix code?
Check out this post to see if it is possible.
Now in code the only way to add a reference field from another data collection is to use the ID. But note that ID is the field name used in the data collection for dashboard and Editor view. When accessing the ID value in code you need to use the field key which is _id.
So in your Table2 you need a column (field) that is of type reference and give it a field name like "Table1 Reference". The editor will generate a field key for you that will look like table1Reference.
Now if you have a record from Table1 that you want to link to Table2 you do something like this:
wixData.query('Table1')
.eq('title', 'uniqueTitle')
.find()
.then((results) => {
if (results.totalCount !== 1) {
throw Error('We didn't get a record from Table1');
}
// Success add this in a new record in Table2
let table1Item = results.items[0];
let table2Data = {
table1Reference:table1Item._id,
anotherTable2Field:"Some info for table2"
};
return wixData.save('Table2', table2Data)
.then((savedRecord) => {
// Successful save!
// Do something here....
});
})
.catch((error) => {
console.log(error);
});
Good luck!
