Results as dict/array of dict?

See original GitHub issue

It would be grand if one could do something like this:

    >>> m = Model()
    >>> print
    [{'id':1, 'name':'foo'},{'id':2, 'name':'bar'}]

i.e., returning each row as a dict. This would be especially handy for returning JSON result sets, and could probably be done using iter to return self._data for the model.

This issue was 8 years old when it was brought to my attention again. Here are the methods you would want to use:

query =
for row in query:  # Each row is a dict.

The information further down is no longer correct.

See comment:

I’m not sure why this should be a part of peewee itself, unless for performance reasons you’re concerned about the overhead of class creation. You can see in flask-peewee some helpers already exist:

You can save by not creating model instances by iterating over the cursor:

db = SqliteDatabase(...)

query =
cursor = db.execute(query)

ncols = len(cursor.description)
colnames = [cursor.description[i][0] for i in range(ncols)]
results = []

for row in cursor.fetchall():
    res = {}
    for i in range(ncols):
        res[colnames[i]] = row[i]

If you want to get even more low-level, you can take the sql generated by peewee and use a row factory:

Though as @coleifer pointed out that this is a 8 years old post, but as this github issue is among the top finds of search engines regarding this topic and I didn’t find a good example code for usage of the pretty useful dicts() method (thank to @coleifer of course), I decided to post one for future readers:

query =

for row in query:


<class 'dict'>
