multi document insert using mongoengine into mongodb

Question

In my flask app I am using MongoeEgine. I am trying to insert multiple documents into my places collection in my MongoDB.

My document class is defined as

class places(db.Document):    name = db.StringField(max_length=200, required=True)       loc = db.GeoPointField(required=True)    def __unicode__(self):     return self.name      a=[]     a.append({"name" : 'test' , "loc":[-87,101]})     a.append({"name" : 'test' , "loc":[-88,101]})     x= places(a) 

The last statement fails

x= places(a) TypeError: __init__() takes exactly 1 argument (2 given) 

I also tried to save this to my instance

places.insert(x) places.save(x) 

both fail. Please help.

Places.objects.insert doesn't take a list of dictionaries it has to be Places instances. Normal operations would be to create individual instances of Places and save or insert eg:

Places(name="test", loc=[-87, 101]).save() Places(name="test 2", loc=[-87, 101]).save() 

However if you want to do a bulk insert you can pass a list of Places instances and call insert on the objects queryset eg:

Places.objects.insert([Places(name="test", loc=[-87, 101]),                         Places(name="test 2", loc=[-87, 101])])
