How to get datasource list and datasource form from another datasource?

Hi!
Sorry, I do not speak English very well.

I want to write a data source plugin, which proxy the request to another data source and apply transformations on the result (at first step WMA or EMA).
Is there a way to get the list of data sources from QueryController and show another data source query form as a part of my data source query?

Yes. You can inject backendSrv and fetch a list of datasources like this (and then filter on name or type):

github.com

grafana/kubernetes-app/blob/ddf616e74c2146e72529316f4fb0348b787e38f4/src/components/clusters/clusters.ts#L29


  document.title = 'Grafana Kubernetes App';
  this.clusters = {};
  this.pageReady = false;
  this.getClusters().then(() => {
    self.pageReady = true;
  });
}


getClusters() {
  var self = this;
  return this.backendSrv.get('/api/datasources')
  .then((result) => {
    self.clusters = _.filter(result, {"type": "grafana-kubernetes-datasource"});
  });
}


confirmDelete(id) {
  this.backendSrv.delete('/api/datasources/' + id).then(() => {
    this.getClusters();
  });
}

Thanks. It works.
And I found how to show the query editor from another data source as part of my datasource query - similarly to https://github.com/grafana/grafana/blob/master/public/app/features/plugins/plugin_loader.ts .
