Exception mapping view results to Object derived from schema.Document about couchdb-python HOT 3 CLOSED

From [email protected] on January 03, 2009 09:40:36

The referenced line of code:

++ data = row.value
++ data['_id'] = row.id

suggests that row.value should be a dict or an object with dict-like properties.

The corresponding view docstring seems out of synch ...

print Person.by_name.map_fun
function(doc) {
emit(doc.name, doc.age);
}

Elsewhere, examples show

emit(doc.name, null);

and indeed, the raw _view output correspondingly shows value=None.

I had some success using a dict as a workaround, along the lines of the following, when defining a view:

function(doc) {
emit(doc.name, {'age':doc.age, 'name':doc.name} );
}

It's hardly a 'map back into the object' but it does avoid the Exception condition. I haven't investigated any
deeper than that simplistic change.

After a little more investigation ... the view in the OP's attached script doesn't support the usage in the code.
If the emit function is changed to:

emit(doc.name, doc);

then the OP's attached script executes without causing an Exception and the retrieved results do indeed
behave as User objects, e.g.

print elem.name

Looks like this isn't a couchdb-python problem.
