node.js - MongoDB _id is convert to ObjectID automatically, but sometime it is not. -

-

I am using a ring that is called to access mongoDB. Mongoscin is a simple wrapper around the Mongo DB Javascript API.

But when I write to mongodibi, sometimes _id is converted to object id, for some time it is not so. Due to different behavior causes many problems when I have to compare _id. For example:

In the company archive, the following document, "Manufacturer" has not been converted to ObjectID, but in "Client" the item is automatically converted into an object.

& gt; ("53d4b452f5b25900005cb999"), ObjectId ("53d4b452f5b25900005cb99a")]} "" {"_ Id": ObjectId ("53d4b452f5b25900005cb999"), "name": "Customer company for 777 - update", "manufacturer": "53d4b452f5b25900005cb998", "SSN": "12-123-1234"}

This is the nodejose code that I specified _id for the "creator" 

  clientCompany.creator = req.session.user.company_id;

This is NodesJS code that I specified _id for "client" 

  var updateObj = {$ addToSet: {clients: resultClient._id} }; // update creator company.clients creatorCompany.update (updateObj, function (error, result) {...}

When I call console.log "req.session.user.company_id" and "Resultclient._id", they both look like a string type. How does a MongoDB end in ObjectID form? If there is an automatic conversion, how can I treat this behavior?

Thank you!

I'm feeling resultClient the result of a query And req .session.user.company_id from your web application In case of tring, you need to create an ObjectId from the string:

clientCompany.creator = mongoskin.ObjectID (request.ession.user.company_id);

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
