使用$ set更新mongo集合

Question

Trying to update a collection and getting invalid syntax from '$'. This script works correctly inside robomongo GUI but not from the terminal..? Probably something simple but I can't seem to figure out why it's giving an error.

    collection.update({'title': "Super excited"},{ $set: {"fb_count": 300}}, {multi: true})

Answer 1

try following code, and I think you can specify multi as argument

collection.update({'title': "Super excited"}, {'$set': {"fb_count": 300}}, multi=True)

pleaser refer to pymongo.collection.Collection.update

Answer 2

你错过了"$set" （和"multi" ）的引号。
