@Marvin how to get deployment_id using prefect library imported
m
✅ thought for 20.0 seconds
Here's how you can get the deployment ID in your code:
Copy code
python
from prefect.runtime.deployment import id as deployment_id

# Access the deployment ID
current_deployment_id = deployment_id
A few important notes: 1. This only works when your flow is running as part of a deployment. It won't work if you're just running a flow locally. 2. The deployment ID is only available during runtime within the deployment's execution context. If you need to get deployment IDs outside of a flow run (e.g., for administrative purposes), you can use the Prefect REST API client:
Copy code
python
from prefect.client import get_client

async def get_deployment_info(deployment_name: str):
    async with get_client() as client:
        deployment = await client.read_deployment_by_name(deployment_name)
        return deployment.id
You can find more details about deployment-related APIs in the Prefect documentation.

Looking at your error and the research, I notice a few potential issues with the automation creation. Here's the correct way to create an automation with an EventTrigger and CancelFlowRun action:
Copy code
python
from prefect.server.schemas.automations import Automation
from prefect.server.schemas.events import EventTrigger
from prefect.server.schemas.actions import CancelFlowRun
from datetime import timedelta

auto_to_create = Automation(
    name="woodchonk",
    description="Cancel flow runs when specific animal events occur",  # Optional but recommended
    enabled=True,  # Optional, defaults to True
    trigger=EventTrigger(
        match_related={  # Use match_related instead of match for object properties
            "genus": "Marmota",
            "species": "monax",
        },
        event_names=["animal.walked"],  # Use event_names instead of expect
        after=None,  # Optional
        within_timedelta=timedelta(seconds=10),  # Use within_timedelta instead of within
        count_within_timedelta=3,  # Use count_within_timedelta instead of threshold
    ),
    actions=[CancelFlowRun()]
)

# Create the automation
created_automation = await auto_to_create.save()  # Note: This needs to be awaited
The key corrections from your original code are: 1. The 
expect
parameter should be 
event_names
and should be a list 2. Use 
match_related
instead of 
match
for object properties 3. 
within
should be 
within_timedelta
4. 
threshold
should be 
count_within_timedelta
5. The 
posture
parameter is not a valid field for EventTrigger 6. The creation method is 
save()
not 
create()
, and it needs to be awaited Also, make sure you're running this code in an async context. If you're running it in a synchronous context, you'll need to wrap it in an async function and use an async runner:
Copy code
python
async def create_automation():
    # ... automation creation code here ...
    return await auto_to_create.save()

# Then run it using:
import asyncio
created_automation = asyncio.run(create_automation())
This should resolve the validation errors you're seeing. The errors occurred because some of the field names and structures have changed in Prefect 3.x compared to earlier versions.
