loopbackjs

问题 I'm trying out Loopback for an API that will talk to Ember. Ember requires JSON to be contained in 'keys', e.g. for an account: { account: { domain: 'domain.com', subdomain: 'test', title: 'test.domain.com', id: 1 } } I've found some advice on the Google group about how to alter the response so that Ember will receive it, using afterRemote hooks. E.g. in my models/account.js: module.exports = function(Account) { Account.afterRemote('**', function (ctx, account, next) { if(ctx.result) { if

问题 Is there a remote method in Loopback data-juggler or any other loopback component which will let me log the query that is executed by the datasource. Eg: If i'm using MySQL connector, then when MODEL_NAME.findById() is called, i should be able to get SELECT * from DATABASE_NAME.MODEL_TABLE where id = WHATEVER_ID Similarly for MongoDB, it should return equivalent mongo query It'd be great if i am able to log query.explain() of mongo here itself I've tried running my app as DEBUG=loopback

问题 I'm using Loopback from Strongloop as a REST framework and ORM. I want to use TypeScript for my business logic. However, Loopback requires JavaScript with a specific shape to support their framework. For example: module.exports = function(Person){ Person.greet = function(msg, cb) { cb(null, 'Greetings... ' + msg); } Person.remoteMethod( 'greet', { accepts: {arg: 'msg', type: 'string'}, returns: {arg: 'greeting', type: 'string'} } ); }; What is the TypeScript code that will generate the above

问题 How to create a permanent access token for a StrongLoop API. Now for every user login it creates an access token. And unnecessary entry in my db I can increase the validity of access token(ttl) as mentioned here. But still it will generate for new login. 回答1: You are mixing up 2 different things. The AccessToken entry creation and the ttl value for the AccessToken. When a user logs in a new AccessToken is created. If the user logs out the AccessToken is removed. If the user logs in 2 times,

问题 I'm trying to add a new REST API method to the loopback-component-storage for downloading all photos from a Container. (see Strongloop loopback-storage-service: how to use StorageService.downloadStream() to download a ZIP of all photos in container?) The following code seems to work, but I'd like to know how to load the storage-handler, handler , and filesystem provider, factory , correctly within the strongloop framework. Also, I shouldn't have to copy the data in datasources.json Any

问题 I am trying to set up a many to many relationship in LoopBack 2.1.2 http://docs.strongloop.com/display/LB/HasManyThrough+relations I tried to POST /api/patients/:patientId/physicians to create a new physician which links the patientId to the new physician, but does not set the appointmentDate in the appointment model. Is there one API call to create this in one transaction? What is the best way to add a new physician to a patient and setting the appointmentDate? Do I have to create my own

问题 I'm using loopback-component-storage with the filesystem provider to upload photos. It works great. But now I have a request to 'export/download' photos to a zip archive. I've put together some code to add another method, downloadContainer() to Container from the file-storage example. It uses the Archiver module, everything seems to work fine, but the browser crashes after I call zip.finalize() I'm expecting to get a save file dialog box instead... Here is my code so far: Container

问题 I'm trying to load an object on a node.js Loopback server and I want to load multiple related objects in the same query. These related objects are on different depths. This is the query: /api/MyUsers/114?filter[include][institutes]=institute&filter[include]=departments&filter[include]=profiles Notice that [institutes]=institute have two levels and departments and profiles only one. This returns me an error: 500 Internal server error. Error: Relation "0" is not defined for User model. On node
