Hi,

I am getting the below error:

```nohighlight
AttributeError: 'tuple' object has no attribute 'field_id'

```

This line is complaining on the below code snippet:

```nohighlight
        field_list = []
        for f in source_rows:
            field_list.append(f.field_id)

```

Where source\_rows returns multiple rows of data, an field\_list being a list should append multiple valules. Some help appreciated in figuring out where I'm messing up.

Thanks,  
Aman

I hope I'm in the correct forum for Python questions.

Nevermind, I figured out the issue, it was with not using the library

```nohighlight
import psycopg2.extras

```

Where I was supposed to handle the tuples correctly with:

```nohighlight
psycopg2.extras.NamedTupleCursor

```
