问题 I have a collection of BsonDocuments, for example: MongoCollection<BsonDocument> products; When I do inserts into the collection, I want the member name to always be lowercase. After reading the documentation, it appears that ConventionPack is the way to go. So, I've defined one like this: public class LowerCaseElementNameConvention : IMemberMapConvention { public void Apply(BsonMemberMap memberMap) { memberMap.SetElementName(memberMap.MemberName.ToLower()); } public string Name { get { throw

问题 So I'm working my way though the Getting Mean book from Manning and following the steps in Chapter 5 I'm trying to use a db on Mongolab as an add-on to Heroku.

How to return/edit REST resource with AngularJS & Restangular

ぃ、小莉子 提交于 2019-12-05 20:16:46
Using Restangular for AngularJS, keep getting an object object from Mongolab. I'm sure it has to do with Promise but not sure how to use/implement this coming from old Java OO experience. (Side note, would something like Eloquent Javascript, some book or resource help me understand the 'new' Javascript style?) The small web app is for Disabled Students and is to input/edit the students, update the time they spend after school and then output reports for their parents/caregivers every week. Here's the code that returns undefined when popping up a new form (AngularJS Boostrap UI modal) I

What is the syntax for Dates in MongoDB running on MongoLab?

落花浮王杯 提交于 2019-12-05 11:02:38
Instead of ObjectId('82he921he982he82') its "_id":{"$oid":"82he921he982he82"} for object Ids, but I have no idea how to create a date value in a document on MongoLab :s If you are using one of the drivers, you create a date via that language's Date class. For instance, in Javascript (like Node.js) it would be 'new Date(11,11,11)'. If using the MongoLab REST API or admin UI you represent dates with this syntax: { "$date": "2010-10-28T23:07:11Z" } Also if an item has: "dateAdded": { "$date": "2012-07-30T15:26:15.321Z" } in one of it's entries, then you can find it by searching: { "dateAdded": {

MongoLab vs Azure Table Storage

你离开我真会死。 提交于 2019-12-05 10:43:42
Take a 100gb database for this example: Azure Storage cost: £6.05/m MongoLab on AWS with 1 node cost: £153.18 /m Am I missing something? Calculated something incorrectly? Can someone clear things up for me here? I would much rather use MongoLab as I really like node/mongoDB. But it seems a much more cost effective solution to go with the Table Storage. I know the differences between Key/Value and Document store and I do prefer the latter. You need to consider that Azure Table Storage (ATS) is storage-as-a-service. You don't need to set up any servers to manage the storage and related CRUD
