I am writing an IBM Cloud Function which uses the python SDK to interface with a Cloudant service. I have the Cloudant service up, the databases populated, and service credentials / API key ready. However when I try to instantiate the CloudantV1 service inside my Function I get a runtime error "must provide authenticator".
I looked up the error in their git repos and it seems like it is trying to setup an authenticator object by looking up values from environment variables, which do not exist in the Function. I just want to pass my API key directly, but I have not found a method to do this. I am using basic code from the examples so I think my calls are correct.
I have considered injecting the environment variables inside the Function, but that sounds like a major hack. I must be doing something incorrectly. Please help me understand what it is. Here is basic Function python code which reproduces the error:
from ibmcloudant.cloudant_v1 import CloudantV1
def main(params_dict):
service = CloudantV1.new_instance()
# unreachable
return { "message" : "hello world" }
There is an example for programmatic authentication at https://cloud.ibm.com/apidocs/cloudant?code=python#programmatic-authentication - it basically looks like this:
from ibmcloudant.cloudant_v1 import CloudantV1
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator
authenticator = IAMAuthenticator('yourAPIkey')
service = CloudantV1(authenticator=authenticator)
service.set_service_url('https://yourserviceurl.example')

I am having some issues migrating my Google MY Business API python code.
My original code looks like:
Get my accounts:
service, flags = sample_tools.init(argv, "mybusiness", "v4", __doc__, __file__,
scope="https://www.googleapis.com/auth/business.manage",
discovery_filename=cfg.discovery_doc_old)
output = service.accounts().list().execute()
accounts = output["accounts"]
Get my locations name per account with the following call:
self.service.accounts().locations().list(parent=account['name']).execute()
For each location I get my insights report with the following call:
service.accounts().locations().reportInsights(name=self.account, body=body).execute()
Now since these calls are going to be deprecated, I need to update this code to the new Business APis. So far I managed to reproduce step 1 & 2 of my old code:
Get my accounts (using the my business account management api):
service, flags = sample_tools.init(argv, "mybusinessaccountmanagement", "v1", __doc__, __file__,
scope="https://www.googleapis.com/auth/business.manage",
discovery_filename=cfg.discovery_doc_new)
output = self.service.accounts().list().execute()
accounts = output["accounts"]
Get my location (using my business business information api):
service, flags = sample_tools.init(argv, "mybusinessbusinessinformation", "v1", __doc__, __file__,
scope="https://www.googleapis.com/auth/business.manage",
discovery_filename=cfg.discovery_doc_gmb_info)
output = service.accounts().locations().list(parent=self.accounts[0]['name'],
readMask='name',
).execute()
locations = output['locations']
Now I am missing the equivalent to the old
reportInsights(name=self.account, body=body).execute()
I haven't found anywhere some similar. I thought maybe I need to add it as the readmask, but also could find any documentation. I basically want to get the values of these metrics for each location using one of the new APIs:
https://developers.google.com/my-business/reference/rest/v4/Metric
I already went through this tutorial, even though I prefer using the client libraries:
https://developers.google.com/my-business/content/basic-setup
but it doesn't tell me where to find these metrics.
I have also tried the same structure as in the old API but I get the error message:
AttributeError: 'Resource' object has no attribute 'reportInsights'
Can someone help me with this? I am quite new to the Google APIs and maybe there is something obvious I missing out :/
Thanks a lot,
Rafael
As #devinthemaking has stated correctly, the reportInsights method is not deprecated and does not have a successor method yet.

I've been following along with the testdriven.io tutorial for setting up a FastAPI with Docker. The first test I've written using PyTest errored out with the following message:
TypeError: Settings(environment='dev', testing=True, database_url=AnyUrl('postgres://postgres:postgres#web-db:5432/web_test', scheme='postgres', user='*****', password='*****', host='web-db',host_type='int_domain', port='5432', path='/web_test')) is not a callable object.
Looking at the picture, you'll notice that the Settings object has a strange form; in particular, its database_url parameter seems to be wrapping a bunch of other parameters like password, port, and path. However, as shown below my Settings class takes a different form.
From config.py:
# ...imports
class Settings(BaseSettings):
environment: str = os.getenv("ENVIRONMENT", "dev")
testing: bool = os.getenv("TESTING", 0)
database_url: AnyUrl = os.environ.get("DATABASE_URL")
#lru_cache()
def get_settings() -> BaseSettings:
log.info("Loading config settings from the environment...")
return Settings()
Then, in the conftest.py module, I've overridden the settings above with the following:
import os
import pytest
from fastapi.testclient import TestClient
from app.main import create_application
from app.config import get_settings, Settings
def get_settings_override():
return Settings(testing=1, database_url=os.environ.get("DATABASE_TEST_URL"))
#pytest.fixture(scope="module")
def test_app():
app = create_application()
app.dependency_overrides[get_settings] = get_settings_override()
with TestClient(app) as test_client:
yield test_client
As for the offending test itself, that looks like the following:
def test_ping(test_app):
response = test_app.get("/ping")
assert response.status_code == 200
assert response.json() == {"environment": "dev", "ping": "pong", "testing": True}
The container is successfully running on my localhost without issue; this leads me to believe that the issue is wholly related to how I've set up the test and its associated config. However, the structure of the error and how database_url is wrapping up all these key-value pairs from docker-compose.yml gives me the sense that my syntax error could be elsewhere.
At this juncture, I'm not sure if the issue has something to do with how I set up test_ping.py, my construction of the settings_override, with the format of my docker-compose.yml file, or something else altogether.
So far, I've tried to fix this issue by reading up on the use of dependency overrides in FastApi, noodling with my indentation in the docker-compose, changing the TestClient from one provided by starlette to that provided by FastAPI, and manually entering testing mode.
Something I noticed when attempting to manually go into testing mode was that the container doesn't want to follow suit. I've tried setting testing to 1 in docker-compose.yml, and testing: bool = True in config.Settings.
I'm new to all of the relevant tech here and bamboozled. What is causing this discrepancy with my test? Any and all insight would be greatly appreciated. If you need to see any other files, or are interested in the package structure, just let me know. Many thanks.
Any dependency override through app.dependency_overrides should provide the function being overridden as the key and the function that should be used instead. In your case you're assigning the correct override, but you're assigning the result of the function as the override, and not the override itself:
app.dependency_overrides[get_settings] = get_settings_override()
.. this should be:
app.dependency_overrides[get_settings] = get_settings_override
The error message shows that FastAPI tried to call your dictionary as a function, something that hints to it expecting a function instead.
I am trying to use the attributeService.getEntityAttributes function to obtain some server attributes of my device. I was using the .getEntityAttributesValues function when working with the 2.x version of Thingsboard and it was working fine. With the current version I am using the following code:
var conf = {
ignoreLoading: false,
ignoreErrors: true,
resendRequest: true
};
var myattr = attributeService.getEntityAttributes(entityID,'SERVER_SCOPE',["myattribute"],conf);
But I get no data or error back. I was using the .getEntityAttributesValues with .then() method but it doesn't seem to work anymore. It says ".then is not a function".
What am I doing wrong? Please help and tell me how to use the new function properly. I am using TB v.3.1.1 CE.
Thingsboard 2.x UI was made with AngularJS.
Thingsboard 3.x UI now uses Angular.
One of the key differences between these frameworks in regards of your problem is the move from Promise based services, to Observable based services.
Let's look at the source of the getEntityAttributes function:
https://github.com/thingsboard/thingsboard/blob/2488154d275bd8e6883baabba5519be78d6b088d/ui-ngx/src/app/core/http/attribute.service.ts
It's mostly a thin wrapper around a network call made with the http.get method from Angular.
Therefore, if we have a look at the official documentation: https://angular.io/guide/http#requesting-data-from-a-server, it is mentioned that we must subscribe to the observable in order to handle the response. So something along the lines of:
attributeService.getEntityAttributes(entityID,'SERVER_SCOPE',["myattribute"],conf).subscribe((attributes) => {…})
I have a situation where I want to import my graph data to database.I am having janusgraph(latest version) running with cassandra(version 3) and elasticsearch(version 6.6.0) using Docker.I have been suggested to use gryo format.So I have tried this command
graph.io(IoCore.gryo()).reader().create().readGraph(ToInputStream.from("my_graph.kryo"), graph);
but ended up with an error
No such property: ToInputStream for class: Script4
The documentation I am following is here.Please take a look and put me in a right procedure. Thanks in advance!
ToInputStream is not a function of Gremlin or JanusGraph. I believe that it is only a function of IBM Compose so unless you are running JanusGraph on that specific platform, this command will not work.
Versions of JanusGraph that utilize TinkerPop 3.4.x will support the io() step and this is the preferred manner in which to load gryo (as well as graphson and graphml) files.
Graph graph = ... // setup JanusGraph instance
GraphTraversalSource g = traversal().withGraph(graph); // might use withRemote() here instead depending on how you are connecting I suppose
g.io("graph.kryo").read().iterate()
Note that if you are connecting remotely - it seems you are sending scripts to the Docker instance given your error - then be sure that that "graph.kryo" file path is accessible to Docker. That's what's nice about ToInputStream from Compose as it allows you to access remote sources.
I'm trying to develop a stand-alone client app that uses web services in a Glassfish container (Metro). About all I have to work from is a wsdl for the wervices I'm trying to use. The wsdl is rife with all kinds of 'wsp:Policy' tags. Looks like IssuedToken, Trust13, ecryption are all utilized.
So I generated some code from netbeans and JAX-WS. Everything went well, but when trying to run the client I get:
'WST0029:STS location could not be obtained from either IssuedToken or from client configuration for accessing the service http://localhost:8080/ ....'
That's when it occured to me that I know nothing about WSS. It doesn't look like any code was generated to deal with security. So, I'll have to go from scratch.
So where to start? Books? Tutorials?
TIA
Metro applies the policy in runtime from either the WSDL or the wsit-client.xml config file. That's why no code is generated related to policies. According to this post it is not possible at the moment to do programatically.
This tutorial explains pretty well some of the things you can do with WSS, and though everything do probably not apply in this case it's still a good read.
The simplest way I've found of generating a client with WSS support is by using the wsimport script from Metro:
cd metro/bin/
mkdir src target
./wsimport.sh -s src -d target -extension -Xendorsed -verbose YourService.wsdl
Then install Metro into your application server (copy the libs to the correct places or run the ant script):
ant -f metro-on-glassfish.xml
Then put your local WSDL file in your classpath (e.g. your resource folder), so Metro can get it at runtime to apply the policies from your generated YourService class:
private final static URL YOURSERVICE_WSDL_LOCATION;
// This is enough, you don't need the wsdlLocation attribute
// on the #WebServiceClient annotation if you have this.
static {
YOURSERVICE_WSDL_LOCATION =
CustomerService.class.getClassLoader().getResource("YourService.wsdl");
}
public YourService() {
super(YOURSERVICE_WSDL_LOCATION,
new QName("http://tempuri.org/", "YourService"));
}
And if you want WS-Addressing you might need to add the feature manually to your binding method (Metro has never generated it for me, so I always have to add it myself).
#WebEndpoint(name = "WSHttpBinding_IYourService")
public IYourService getWSHttpBindingIYourService() {
WebServiceFeature wsAddressing = new AddressingFeature(true);
IYourService service =
super.getPort(new QName("http://xmlns.example.com/services/Your",
"WSHttpBinding_IYourService"), IYourService.class,
wsAddressing);
return service;
}
