How can I pass default values in the pipeline and not at runtime. I am using resources. I have defined resources

resources:
  environs:
     config:
       year: 2021

How can I tell dagster that when launching from the dagit UI, if no year config us passed, use 2020. In my Python file, I have the job defined as

@job(resource_defs={"environs": make_values_resource(year=2020)}
def pipeline_job():
   job_a(job_b)

The idea is to pass the default value in the job definition but I am getting errors. However, when I do this, I don't get any errors:

@job(resource_defs={"environs": make_values_resource(year=int)}
def pipeline_job():
   job_a(job_b)

Any help?

Hi Qwame. You can usually provide a

default_value

argument when you define the resource config schema. Can you share the body of

make_values_resource

?

I don't have the body, that's all I got in there

make_values_resource(year=int)

Do I have to define

make_values_resource

elsewhere other than what I have in the code?

make_values_resource

looks like a resource factory function that defines a resource definition using

@resource

. Usually you can provide that definition with a config schema and provide a default value there

Is there an example I can look at as I'm not quite understanding it here

Have you checked out the

Resources

section on our docs site: https://docs.dagster.io/concepts/resources

Will that not mean I have to pass the config to an

op

instead of a

job

?
