Fetch D3.js Array From A Url

This is the kind of data that I have { '_id' : ObjectId('kdahfa'), 'minTime' : ISODate('2016-04-02T00:00:00.000+0000'), 'maxTime' : ISODate('2016-04-02T00:11:00.000+0000'), 'Time

Solution 1:

a = dbcoll.find_one({},{'_id':False})

In this line, you are only querying for one entry in your database, that is why the result returned is a single object instead of an array (probably you also need to change the first parameter {} to [] or something to denote array but I am not familiar with dbcoll.

You need to change find_one into find or something, and you will get an array.

Then the post-processing, you needs to iterate through the array of a:

a = a.map(function(b){
     b['minTime'] = str(b['minTime'])
     b['maxTime'] = str(b['maxTime'])
     return b;
}

In MongoDB there is a method find: https://docs.mongodb.com/manual/reference/method/db.collection.find/
