How do I make the developer1 column to have id data like this.
The purpose of this is, I want to import CSV with the id data. like this. So after I import, the developer1 column gets related to developers table using id column
the Identification Column is not for identifying unique records in a table. This is a purely visual representation of a related object in the parent table - so that instead of a “1: 1 relation” you can choose a column whose value will be shown in it, e.g. developer’s name.
Just rename the id column in your CSV to objectId, and it will be overridden.
