Setting up the clients

1. Create a new realm, not recommended to use master realm

2. Setup the clients

Each service uses a client

• Backend:
  1. Create a client for the back-end
  2. Set your access type to confidential
  3. Standard Flow Enabled: On
  4. Service Account Enabled: On
  5. Service Account Roles --> Client Roles --> realm-management (user related roles)
• Frontend:
  1. Create a client for the front-end
  2. Access Type: public
  3. Standard Flow Enabled: on
  4. Direct Access Grants Enabled: On

Environment Variables

OIDC_RP_CLIENT_ID and OIDC_RP_CLIENT_SECRET refers to backend client credentials

<KEYCLOAK-SERVER-URL> could be https://<your-keycloak-host>/ or https://your-keycloak-host/auth/ depending on the keycloak version

You can get the OIDC_RP_* variables at: https://your-keycloak-host/realms/<realm-name>/.well-known/openid-configuration

Ex for keycloak 16.1: http://127.0.0.1:8080/auth/realms/engine_realm/.well-known/openid-configuration

engine_realm as realm name

Running

Install docker

Create an .env file in the project root and add the above environment variables

For authentication, we use Keycloak, you need to run it locally:

• Documentation

Execute docker-compose build to build application

Execute docker-compose up to up the server

Very good, your application is running 🚀

weni-engine's Issues

Unnecessary template message ViewSet

The file: connect/api/v1/wpp_templates/views.py has a seemingly unnecessary ViewSet.

1. The views.py file is not called anywhere;
2. The view's queryset is using a model that does not exist in the project;
3. the get_last_template_sync method does not use the get_object method so it makes no sense to use a ViewSet, since the queryset is not used;
4. This endpoint does not need to exist, as the project is not instantiated at any time. This endpoint can be called directly from Integrations.

Need for improvement of README file

The readme file is missing important information such as:

• Deployment instructions of the project
• Need more development/getting started instruction
• Travis link is broken

Env Variables for Dev Env

I would like to contribute to weni and trying to set up a dev env on my laptop
Is there some example I can follow about how to do that? I guess even an example .env file would be enough to get me started

Channel delete method duplicated in Flows client

Are these methods duplicated?

https://github.com/weni-ai/weni-engine/blob/main/connect/api/v1/internal/flows/flows_rest_client.py#L266
https://github.com/weni-ai/weni-engine/blob/main/connect/api/v1/internal/flows/flows_rest_client.py#L293

`template_flow` method should be outside the client

Ideally, the FlowsRESTClient class should have a clear responsibility: contain flow clients

The template_flow method appears to be out of place among the clients. Furthermore, the name is not very suggestive either
https://github.com/weni-ai/weni-engine/blob/main/connect/api/v1/internal/flows/flows_rest_client.py#L341
