composer rest server - How to get the block chain models into the custom models (common/models)

umrb2010@...
 

We are customizing the composer rest server.
For this we added few custom models to common/models. From this custom model trying to get the Block Chain model
The block chain models are empty in custom model. However the block chain models are coming into boot.js.

Is there any way that  we can retrieve the block chain models into common/models?

server/root/boot.js - 
-------------------------
module.exports = function(app) {
 //console.log(app);
  var modelNames = Object.keys(app.models);
  var models = [];
  modelNames.forEach(function(m) {
    var modelName = app.models[m].modelName;
    if (models.indexOf(modelName) === -1) {
      models.push(modelName);
    }
  });

common/models/
---------------------------
var loopback = require('loopback');
var app = loopback(); //getting app object
  var modelNames = Object.keys(app.models);
  var models = [];
  modelNames.forEach(function(m) {
    var modelName = app.models[m].modelName;
    if (models.indexOf(modelName) === -1) {
      models.push(modelName);
    }
  });
 
Thank you!

Re: Composer asset usage

Bob <dillbob@...>
 

In composer, you would identify an item of type Array. This allows you to let it hold any number of items. You can do the same thing by identifying Item as a string and then putting an arbitrarily long JSON string in it holding all of the items.

or is there any alternatives ways when handling transactions like sales orders in the block chain via composer ? Many transactions have a lot of items (items) to be sold. Thereby how to record in the ledger ?

Is there any PoC for EKYC and Wallets on top of Hypeledger Composer?

hassan@...
 

Dear All,

My name is Hassan, and I'm building the first BaaS provider in Egypt. I would love to use the Hyperledger network to build 2 solutions related to Identity Management (Electronic Know Your Customer) EKYC, and Building Digital Wallets for different purposes, and wanted to know if there's any PoC that's already built regarding any of those 2 use cases?


Thank you!

Re: Regarding Implement Hyperledger blockchain in our project.

Alberto Venturini <aventurini@...>
 

Hi Nilesh,

I would just start with the Composer tutorials (https://hyperledger.github.io/composer/latest/tutorials/tutorials.html). I used these tutorials a few months ago when starting off with Composer, and I have found them quite helpful.

Also, be aware that Hyperledger Composer has been put on hold a few months ago (see e.g. https://hackernoon.com/hyperledger-composer-has-been-put-on-pause-what-are-your-options-now-dfc3a97a6308.)

If you are new to blockchain and Hyperledger, my advice would be to have a look at Composer, and perhaps build a proof of concept or a first project iteration with it. Composer does hide away some of the complexities of Fabric, so it should be easier to start with. But I'd refrain from building a production system with Composer.


Also, if you use Composer, sooner or later you will also need to learn how Fabric works - especially when you want to deploy your Composer project onto a non-trivial Fabric network. In order to learn about Fabric, I would start with one of the whitepapers, e.g. https://arxiv.org/pdf/1801.10228.pdf.

Error getting the participant registry when running tests

aventurini@...
 

Hi all,

I am setting up some unit tests for my Composer business network and I am running into an error. I'm pretty much following the same test setup as the sample networks (https://github.com/hyperledger/composer-sample-networks/blob/master/packages/vehicle-manufacture-network/test/script.js)

I'm trying to get the participant registry in the beforeEach function:

const participantRegistry = await businessNetworkDefinition.getParticipantRegistry(namespace);

and running into the following error message:

Error: Object with ID 'Participant:<my namespace>' in collection with ID '$sysregistries' does not exist

Does anyone have a clue as to why I would be getting this error?

The reason I am trying to get the participant registry is that I have some assets which hold a reference to participant objects, and I would like to test that my transaction creates assets that have appropriate participant references.

Thank you,
Alberto
