txng.collection(col).insert(row, return_new=True) does not return a new row about python-arango HOT 5 CLOSED

So it looks like you might be able to do something like this in your query:

txn = db.transaction(write=col_name)
result = txn.execute(
    command='''
    function (params) {{
        var db = require('internal').db;
        var a = db.{col}.save({{ '_key': '1', 'val': params.one }});
        var b = db.{col}.save({{ '_key': '2', 'val': params.two }});
        return [a,b];
    }}'''.format(col=col_name),
    params={'one': 3, 'two': 4}
)

And that should return the meta information including the _key on each object.

ok, this behavior is documented.

Let me rephrase: how can you obtain the _key of all inserted documents during a transaction?

from python-arango.

It looks like this could be handled in a relatively straightforward manner by maintaining a javascript map of outputs to return. However, I think the following code should be moved to transaction.py handle_request (from 104, collections/standard.py insert)

if self._conn.type != 'transaction':
            command = None
        else:
            command = 'db.{}.insert({},{})'.format(
                self._name,
                dumps(document),
                dumps(params)
            )

I'll probably submit a request to do this tonight.

@joowani take a look, but I think I addressed this in #pr66

@zopyx In python-arango version 4.0.0, transactions return job objects allowing result retrieval after commit. You can read more about it here. Please note that 4.0.0 is not backward compatible and you may need to significantly change your code. Cheers.
