Issue in django sls management commands

[mmoallemi99]

Hi People,

I'm using serverless-wsgi==1.7.6 alongside serverless==2.2.0.

The problem is when I intend to run a management command as stated in the documents I must be executing this:

sls wsgi manage -c "update_containers"

But this raises an exception with this error message:

 
  Error --------------------------------------------------

This command is the same as stated in the repo README.md file, but changing -c to --command fixes the problem!

So am I missing something here or -c is a broken argument?
And I would like to contribute to fix the problem, should I be updating the documents or fix handling -c arg just like --command?

Any guidance would be appreciated <3

[logandk]

Indeed, this is the same issue as #132 - serverless started utilizing the -c argument

I haven't had time to look into it yet, but I think we should consider changing -c to another shorthand for --command. If you can determine which other shorthand would make sense, which is not reserved by the framework already, it should be a simple matter of replacing it in the code, tests and readme

[mmoallemi99]

I guess if we start brainstorming about it we can end up with some valid candidates for the issue.

sls wsgi manage -t "<command_name>"
sls wsgi manage --task "<command_name>"

sls wsgi manage -a "<command_name>"
sls wsgi manage --action "<command_name>"

sls wsgi manage -x "<command_name>"
sls wsgi manage --execute "<command_name>"

And I think that it's better if we just change --command and -c together and deprecate --command in future.

@logandk up

[logandk]

Sorry, I haven't had any time to spare for this project in a while - I like your first proposal (-t/--task) if that flag is available. Not sure if you're still interested, but otherwise I'm leaving this comment for anyone else to pick up.

[mmoallemi99]

Awesome!
Yes I'm still interested, I will take a look at it this weekend and open a PR so we can discuss further.

Cheers

I started to take a look at this, none of the shortcuts were resolving for me until I added

this.hooks = {
	initialize: () => {
		this.options = this.serverless.processedInput.options;
	}

from serverless/serverless#9452

Also nothing I tried could get me past the original error I was seeing, maybe the api for invoke has changed?

ServerlessError: Function "undefined" doesn't exist in this Service

@carlosfunk any ideas on how to solve this?

[himynameisben]

You can use invoke to solve this issue temporarily.
For example,
change from

sls --function {function name} wsgi manage local --command 'check --list-tags'

to

sls invoke --function {function name} -d '{"_serverless-wsgi":{"command":"manage","data":"check --list-tags"}}'

same as others command
change from

sls wsgi exec -c "import math; print((1 + math.sqrt(5)) / 2)"

to:

sls invoke local --function {function name} --data '{"_serverless-wsgi":{"command":"exec","data":"import math; print((1 + math.sqrt(5)) / 2)"}}'

[george-silva]

Exacly what we did @himynameisben !
