python - How to use AND condtion in mongokit when a key has multiple values -


i have key in document named "tag". has structure this: 

"tag": [     {       "schemename": "http:\/\/somesite.com\/categoryscheme2",       "name": "test tag2",       "value": 1,       "slug": "test_tag2"     },     {       "schemaname": "http:\/\/somesite.com\/categoryscheme3",       "name": "test tag3",       "value": 1,       "slug": "test_tag3"     }   ],

the values of tag can passed ',' separated. how can use values in , condition saying return enrty having tag = test_tag3&test_tag2

itried : conditions['tag.slug'] = { '$and': tags } tags array of tags got :

pymongo.errors.operationfailure  operationfailure: database error: invalid operator: $and

use $in instead of $and:

conditions['tag.slug'] = { '$in': tags }
