inserting items in list in mongodb document

Question

I have a document like this ``` { "_id" : "decfed9a04b997d", "pushed_list" : [ ] } ``` and I want to update/insert "pushed_list" by these sub items stored in a python list ``` lis1 = [ { item : 'item1', desc : 'desc_item1' }, { item : 'item2', desc : 'desc_item2' }, { ........................ } ] ``` I tried this ``` db.monitor.update({'_id' : 'dbjkdd'}, { '$push':{'pushed_list': {'$each':{lis1}}}}) ``` Its giving me an error. ``` Traceback (most recent call last): File "monitor.py", line 13, in <module> db.monitor.update({'_id' : 'dbjfdd'}, { '$push':{'pushed_list': {'$each':{lis1}}}}) TypeError: unhashable type: 'list' ```

Accepted Answer

I found the answer, pretty foolish on my side; just have to remove extra braces `{}`

Instead of this

```
db.monitor.update({'_id' : 'dbjkdd'}, { '$push':{'pushed_list': {'$each':{lis1}}}})
```

Use this

```
db.monitor.update({'_id' : 'dbjkdd'}, { '$push':{'pushed_list': {'$each':lis1}}})
```

i.e remove `'{'`after `'$each'` and its corresponding `'}'`
