Request Dynamic Parameters

[dwestness]

I would like to request the ability to define dynamic parameter sets.

For example, Only display parameter #3 if user has selected applicable value first for parameter #2 for instance.

Hi @dwestness, how many dynamic parameters do you have? And are they free-text or list values? You might have a look at:

• https://github.com/bugy/script-server/wiki/Script-config#include
• https://github.com/bugy/script-server/wiki/Script-config#values

Thanks @bugy for pointing me in this direction. I had overlooked the option for dynamic includes here. I was able to get it working for my immediate needs perfectly.

For this use case i have a list parameter in main with options for "Add, Remove, Query" and have another parameter that becomes available whenever either "Add" or "Remove" is chosen and not available when "Query" is selected.

For this I had to create 2 include JSON files to support the ${PARAMETER_NAME} variable (one Add.JSON and one Remove.JSON) for the target. The files are identical in this case. Does that seem like the right way to go about it?

[bugy]

Yes, this seems the only way for now

@dwestness sounds like something I'm trying to achieve as well. Care to share an example?

@dwestness , I am unable to understand how to use this feature. Can you explain me clearly with an example?

[bugy]

@agail @sbalakrishna for the usecase above, script json should config smth like:

{
  "include": "${Parameter name}.json"
}

And then create 2 json files (identical to each other), Add.json and Query.json (according to possible values). Both of these jsons should have body like:

{
  "parameters": [
    {
       "name": "query text"
    }
  ]
}

@bugy I must have a thick skull, all these includes are very confusing to me. I guess it's easy when you know how, but I've been at it for a couple of hours, a small tutorial would be nice.

For example, in UI I wish to have three fields: [device] [action] [node] Device is a list with predefined values; device1 and device2 Action is a list with predefined values; on and off Node should be populated with the values of selected [device]. The field Node newer show up, is that how its supposed to work or am I missing something? Running most recent dev docker image

mockup.json

{
  "name": "Dynamic select",
  "script_path": "bash -x -c \"echo ${@};env\"",
  "include": "${PARAM_DEVICE}.json",
  "parameters": [
    {
      "name": "device",
      "type": "list",
      "values": [
        "device1",
        "device2"
      ]
    },
    {
      "name": "action",
      "type": "list",
      "values": [
        "on",
        "off"
      ]
    }
  ]
}

device1.json

{
  "parameters": [
    {
      "name": "nodes",
      "type": "list",
      "constant": false,
      "values": {
        "script": "scripts/test/mockup.sh device1 list",
        "shell": false
      }
    }
  ]
}

Hi @agail you don't need to use include feature, this is needed when you want to add or remove a parameter dynamically. This is what the ticket's author was asking You just need dynamic values, so remove the include section and the file, and move the node parameter to the main json And then replace "device 1" in values with ${device}. I'm not sure, why you were using PARAM_DEVICE

Thanks for the quick reply @bugy, I'm slowly getting the grasp of it. Since I apparently misunderstood the whole include thing, I thought I had to use the PARAM-variables produced. Without knowing the named PARAM to use, listing them with env at script execution would let med identify them. Completely wrong, obviously ;)

+ env
PYTHONUNBUFFERED=1
HOSTNAME=test-script-srv
[snip]
PARAM_ACTION=on
PARAM_DEVICE=device1

[bugy]

Yeah, parameters are resolved before env variables are available
