PyMongo and Flask's Jsonify contains escape slashes

Question

I\'m trying to make a response using Flask from a Mongodb collection:

@app.route(\'/stories\', methods = [\'GET\'])
def get_stories():
    stories = db.stor         


        

Answer 1

You are encoding twice:

json_docs = [json.dumps(doc, default=json_util.default) for doc in stories]

resp = jsonify(data=json_docs)

Now each entry in json_docs is a string representing a JSON object.

Remove the json.dumps() call:

resp = jsonify(data=stories)

or use flask.json.dump() with a Response():

resp = Response(json.dumps({'data': stories}, default=json_util.default),
                mimetype='application/json')

This lets you use your json_util.default handler on the cursor objects still.
