问题 We're developing a SaaS accounting product that uses the Loopback REST framework and allows authenticated end users to create new tables in their own database instance (MySQL or PostgreSQL). QUESTION : How can we create a new root level Looback REST endpoint in code (on the fly) to access the new table? For example if the user adds a new table named 'cars' we need to expose a new root level REST endpoint in code called '/api/cars' that uses the persisted model to provide full CRUD capability

Try upgrading and making sure the user model is attached to a data source. Below are the steps to do this. // # Verify version // Ω slc version // slc v2.1.1 (node v0.10.9) // # upgrade with `npm install strong

问题 I am trying to use Loopback as a mobile backend. I am also following this example: http://docs.strongloop.com/display/public/LB/Introducing+the+Coffee+Shop+Reviews+app After I login on my iOS device, I receive an access token. All good. Now I want to call an endpoint that requires authentication. Just calling the endpoint gets me the message "AUTHENTICATION REQUIRED". So I try to attach the access token to the request parameters as {"access_token":"1241341234513..."}. However, nothing happens

问题 In this loopback tutorial we can see how own can create model relationships http://docs.strongloop.com/display/public/LB/Tutorial%3A+model+relations#Tutorial:modelrelations-Createmodelrelations Is the same possible in StrongLoop Arc?

问题 My App has this Events Models. If I create another Model: Dates... so an Event can have multiple Dates, should I use Events EmbedsMany Dates? or is better to use Events hasMany Dates and Dates belongsTo Event? What's the difference? New Dates to the event might be added later after the Event been created. I might be using a MySQL database, don't know if that has something to do. 回答1: Query on model which has EmbedsMany relation will include instance(s) of related detail model in the result.
