kandi X-RAY | awsarn Summary
awsarn is an ARN parser. More specifically, this is a Go (golang) library for validating, parsing, and comparing AWS ARN resource identifier strings. This package also provides the capability of determining if one ARN is a superset of another. This is useful for safely eliminating redundant ARNs from a set. Created by Jay Taylor and used by Gigawatt.

QUESTION
I feel like I'm chasing my tail here and so I've come to your fine folks to help me understand where I've screwed up and why my thinking on this must be flawed in some way.
I'm writing an API in DRF and while it doesn't have a lot of tables in the DB, there are many to many relationships in the DB which makes it feel complicated, or at least it makes it difficult to just view the db tables and intuitively understand what's related.
First my model. I'm getting this when attempting to POST a new object to the jobs
model. I'm needing to validate that the requesting worker has the permission to create a job
with the related target
and workergroup
ANSWER
Answered 2020-May-21 at 00:00I'm not 100% sure I'm on the right track here, but it seems you might have a problem of duplicate/multiple results. You should try and use .distinct()
on the Queryset
in WorkerGroupPKSerializer
(also, see Django docs). You used a ForeignKey
on the customer
property of the Worker
model, so that makes it possible to have multiple Worker
's belonging to the same WorkerGroup
matching the filter query, thus returning the same WorkerGroup
twice. So when the id
of that WorkerGroup
is POST
ed, the get()
will match two results, throwing that error.
Commenting out seems to clear the error, and this would be because of the fact that you're also commenting out many=False
, thus, .get()
is not called anymore. But as mentioned in the question, this would disable the custom queryset used to filter on.
QUESTION
I am trying to load a YAML file in python, modify it and dump it back. The YAML looks like this:
...ANSWER
Answered 2019-Jun-25 at 13:49You can try to do this with PyYAML, but you'll need to load the block style literal scalar
(that is what such a multi-line construct indicated by |
is called) in
a subclass of string, make sure you can modify it, then on dumping use a special representer
for that subclass that again dumps as a literal scalar.
The easy way to accomplish this is upgrading from PyYAML to
ruamel.yaml
(disclaimer: I am the author of that package), not only does it preserve
the literal block it also supports the more up-to-date YAML 1.2 spec (issued 2009),
preserves comments and tags, integer and float formats, and (optionally) superfluous quotes:
