@Marvin how do you access a functions parameters from the a task decorator
m
To access a function's parameters from the task decorator in Prefect, you generally need to define the function normally and then apply the
@task
decorator from Prefect to it. The parameters of the function are then accessible within the function body as usual. Here's an example of how to define a task with parameters:
Copy code
python
from prefect import task

@task
def my_task(param1, param2):
    # You can now access param1 and param2 within this task
    print(f"The parameters are {param1} and {param2}")
When you call
my_task
with arguments, Prefect will handle those parameters:
Copy code
python
my_task_run = my_task.bind(param1="value1", param2="value2")
If you need to customize task definition, you can use optional keyword arguments provided by the
@task
decorator according to the Prefect documentation on tasks. Some of these arguments are: - `name`: An optional name for the task. - `tags`: An optional set of tags to be associated with runs of this task. - `cache_key_fn`: An optional callable that generates a string key for task caching. - `max_retries`: An optional number of times to retry on task run failure. - `retry_delay`: An optional number of seconds to wait before retrying the task after failure. Please visit the provided link to the documentation for more details on customizing your tasks.

i think you're looking for something like this?
Copy code
@task(task_run_name="Process {foo}")
def process(foo: str):
  pass
s
yes. though not a string, a bool like this:
@task(value={foo})
def do_something(foo: bool):
pass
n
can you explain what you're trying to do?
value
is not a valid kwarg there
s
sorry... my bad - I'm trying to set refresh_cache on the task depending on params passed to the function.
similarly I'm trying to set the cache_expiration_time
n
ahh you want
with_options
Copy code
@task
def foo():
  pass

new_foo = foo.with_options(refresh_cache=True if condition else False, ...)
new_foo()
s
ok. I'm looking at that documentation now. Awesome, looks exactly like what I need.
Thanks!!
