Run actions with socket.io about django-rasa-sockets

[vkresch]

Ok I solved it :). Your bot.py file has to look like this:

from rasa_core.agent import Agent
from rasa_core.channels.socketio import SocketIOInput
from rasa_core.interpreter import RasaNLUInterpreter
from rasa_core.utils import EndpointConfig

# load your trained agent
interpreter = RasaNLUInterpreter("models/nlu/default/bot/")
MODEL_PATH = "models/dialogue"
action_endpoint = EndpointConfig(url="http://127.0.0.1:5055/webhook")
agent = Agent.load(MODEL_PATH, interpreter=interpreter,
                   action_endpoint=action_endpoint)

input_channel = SocketIOInput(
	# event name for messages sent from the user
	user_message_evt="user_uttered",
	# event name for messages sent from the bot
	bot_message_evt="bot_uttered",
	# socket.io namespace to use for the messages
	namespace=None
)

# set serve_forever=False if you want to keep the server running
s = agent.handle_channels([input_channel], 5500, serve_forever=True)

Put your actions folder in rasachat and don't forget to start the action server:
python -m rasa_core_sdk.endpoint --actions actions
That's all :)

Nice @Alexmhack even better! Thanks!

Nicely done, @Blind0ne. Working with custom actions needs one more command prompt or terminal in linux which makes three in total, one for django server, second for rasa socket server and the third for custom actions.

Instead of using bot.py file you can simply run the below command also

python -m rasa_core.run -d models/dialogue -u models/current/nlu --port 5500 --credentials credentials.yml

And credentials.yml should be the same as the rasachat/credentials.yml

Reopen or create another issue anytime.

Hey, @vkresch I needed some help with this repo. There seems to be some problem with the socket.io client-side code, each request is getting a 400 BAD REQUEST error in the browser console, can you take a look by running the code and see if it's working for you.

@Alexmhack Hello, it's same situation with me. It gives always 400 when I tried to connect and chat with bot

Have a look at this issue and what do you think is the problem that is causing this unexpected error.

We have tried,

1. Changing code for client-side socket.io in static/js/chat.js but nothing seems to work.
2. Adding corsheaders to the Django backend and allowing the rasa endpoint for CORS.
