how filter works?

[ghost]

Could you please provide example of how plumbum filter works? I wasn't able to figure out how it work and receiving errors all the time.

Traceback (most recent call last):

Can you provide the command/usage you employed that generated this output?

@paul-krohn Hi, this is the command that I executed. :) Thank you for the quick response.

vagrant@vagrant:~$ plumbum -r us-west-1 -f internal --toke elb.name='internal.us-west-1.elb.amazonaws.com' cloudwatch-to-graphite/sample_templates/elb.yml.j2 AWS/ELB

[paul-krohn]

There are a few problems here.

• your filter has to take the form of key=value; this is not clear in the docs
• filtering on objects that have a name (ie ELBs), as opposed to an ID (ie EC2 instances), is limited to the attributes in the AWS API; tags are not supported and this is not clear in the docs.
• filtering is broken! This happened because there are no tests for it.

Can I interest you in perhaps fixing any of these things? It would be great to have another maintainer on board.

There were a number of changes recently. Any idea where / when the filtering broke?

[paul-krohn]

I've never used the filtering, so I've no idea when it worked. :(

[tmclaugh]

@jasonatfleepio what version of the package? See #37 which is in release 0.9.2.

The template and namespace argument were swapped in a recent PR. I reverted it back.

[ghost]

uh, I'm in 0.9.0.

vagrant@vagrant:~$ plumbum --version
0.9.0

[tmclaugh]

Try 0.9.2 and your issue should go away.

@tmclaugh How can I install 0.9.2 with pip? I was installed with pip upgrading to 0.9.2, but still showing me 0.9.0

We'll need a push of tags 0.9.4 and 0.9.5 to PyPi before @jasonatfleepio can validate recent changes address his issue.
