Issue encountered: Unable to add MongoDB object to database

Recently, I have encountered an issue with a script that looks like this:

use first_db;

advertisers = db.agencies.find( 'my query which returns things correctly );

close first_db;
use second_db;

db.advertisers.insert(advertisers);

This error message pops up when I try to run it:

Tue Jun  5 14:15:07 TypeError: advertisers.toJSON is not a function (shell):1

Any ideas on how to resolve this? Should I convert the original result to JSON before inserting it? or do I need to utilize a specific function?

Your insights are much appreciated!

Answer №1

One issue you may be encountering is that the find() method in MongoDB returns a cursor instead of the actual data itself. To access the data, you will need to iterate over the results returned by the cursor and store them in a variable.

You should refer to the following sections in the documentation for more information: find() and cursors.
