Issue passing select parameters to desktop app

Get Help
1

Hi,
I’l trying to make some changes to the desktop app, by using dynamic forms, but somehow I can’t make the parameters set in the form to be properly passed onto the submit script. We are running version 2.0.27

This is the current form:

attributes:
    bc_num_slots:
        default: '4'
        label: CPUs
        max: '128'
        min: '4'
        widget: number_field

    bc_vnc_idle: 0

    bc_vnc_resolution:
        required: true

    desktop: xfce

    memory:
        default: '16'
        label: Memory (GB)
        max: '500'
        min: '16'
        widget: number_field

    gpu:
        widget: select
        label: "GPU"
        options:
        - ['No', '0', data-hide-partition: true]
        - ['Yes', '1']

    partition:
        label: "Partition"
        widget: select
        options:
        - ["pascal", "pascal"]
        - ["a100", "a100"]

    reservation:
        label: Especial resource reservation granted by sciCORE (optional)
        value: ''
        widget: text_field

cluster: scicore
form:
- bc_vnc_idle
- bc_num_slots
- memory
- bc_vnc_resolution
- bc_num_hours
- gpu
- partition
- desktop
- reservation
submit: submit/submit.yml.erb
title: sciCORE Destkop

And the submit script:

<%-
  case partition
  when "pascal"
    slurm_args = ["--gres=gpu:1", "--partition", "pascal"]
  when "a100"
    slurm_args = ["--gres=gpu:1", "--partition", "a100"]
  else
    slurm_args = ["--partition", "scicore"]
  end

%>

---
batch_connect:
    template: "vnc"

script:
  native:
    - "-n"
    - "<%= bc_num_slots.blank? ? 1 : bc_num_slots.to_i %>"
    <%- if  not reservation.blank? %>
    - "--reservation=<% reservation %>"
    <%- end %>
    <%- if not memory.blank? %>
    - "--mem=<%= memory %>G"
    <%- end %>
    <%- slurm_args.each do |arg| %>
    - "<%= arg %>"
    <%- end %>

The dynamic form works and partition selection only shows when I ask to use a GPU, but then even if in the POST request the partition is sent correctly:

batch_connect_session_context[cluster]	"scicore"
batch_connect_session_context[bc_num_slots]	"4"
batch_connect_session_context[memory]	"16"
batch_connect_session_context[bc_num_hours]	"1"
batch_connect_session_context[gpu]	"1"
batch_connect_session_context[partition]	"pascal"
batch_connect_session_context[reservation]	""
commit	"Launch"

I always end up on the default non GPU partition, and inspecting the user_defined_context.json I see that the partition is not correctly passed: partition "#<Enumerator:0x00007fc7188d7228>"

There is surely some detail that I’m missing but after several iterations and attempts I can’t figure it out…

Any pointers or suggestions?

Thanks!

Rename partition to something different. That comes from a Ruby issue that that object is enumerable and partition has a special meaning to that object.
