when I’m trying to let user select queue name from drop-down widget aka “select”, I’m not able to do it with the default attribute `bc_queue`.

Example:

`/etc/ood/config/apps/bc_desktop/(redacted).yml`:

when using custom attribute (`bc_queue1`) - works as expected - I can see the “select” widget and select “cpu” or “gpu” partition:

```auto
attributes:
    bc_account: ''
    bc_email_on_started: 0
    bc_num_slots: 1
    desktop: xfce
    bc_queue1:
      label: Slurm partition
      widget: "select"
      value: "cpu"
      options:
        - ["normal","cpu"]
        - ["GPU","gpu"]
cluster: (redacted)
title: Cluster Desktop
form:
  - bc_queue1

```

when I’m using default attribute name (bc\_queue instead of bc\_queue1 above ):

```auto
attributes:
    bc_account: ''
    bc_email_on_started: 0
    bc_num_slots: 1
    desktop: xfce
    bc_queue:
      label: Slurm partition
      widget: "select"
      value: "cpu"
      options:
        - ["normal","cpu"]
        - ["GPU","gpu"]
cluster: (redacted)
title: Cluster Desktop
form:
  - bc_queue

```

i see just standard textbox and the `select` widget is ignored.

Is there any good reason for that?  
Isn’t that bug?

Indeed I’d prefer to use default attribute name because otherwise I’d be forced to use patched bc\_desktop. This is indeed not un-doable but I like to be aligned with upstream and not letting every `dnf update` break my setup.

cheers from Prague.

ok, the solution was to create custom attribute of required type.  
So to modify bc\_desktop config `/etc/ood/config/apps/bc_desktop/(redacted).yml`:

```auto
attributes:
    bc_account: ''
    bc_email_on_started: 0
    bc_num_slots: 1
    bc_queue: null
    desktop: xfce
    slurm_partition:
      label: Slurm partition
      widget: "select"
      value: "cpu"
      options:
        - ["normal","cpu"]
        - ["GPU","gpu"]
cluster: (redacted)
title: Cluster Desktop
form:
  - slurm_partition
  - bc_vnc_idle
  - desktop
  - bc_account
  - bc_num_hours
  - bc_num_slots
  - node_type
  - bc_queue
  - bc_vnc_resolution
  - bc_email_on_started

submit: "submit/my_submit.yml.erb"

```

and create `/etc/ood/config/apps/bc_desktop/submit/my_submit.yml.erb` containing:

```auto
---
script:
  queue_name: <%= slurm_partition %>
  native:
   - "-N"
   - "<%= bc_num_slots.blank? ? 1 : bc_num_slots.to_i %>"

```

works. 🙂

`bc_queue` is hard coded to be just a text field. We can change that so that you can override it (we just did it with `bc_account` because it was hard coded too).

That said - we’re also looking into auto populating partition information. Do you only have those 2 partitions?

See here for more info on that.

I have more partitions at my cluster(s), but to bc\_desktop users, only ‘gpu’ and ‘cpu’ partititions are relevant - other partitions are just defining different (_worse_) QoS.

Thanks, the trick there presented by @Micket with `apps/dashboard/initializers/ood.rb` is really nice.

It could be really useful to us to present eg. available Lmod/Easybuild software modules / conda environments, etc. to user in OOD gui. I have already one open request to implement `conda`/`venv` “bring-your-own” jupyterlab environment (conda+venv) so this can help me avoid hardcoding things into our Ansible.

This is coming in 2.1. You can the features currently in nightly: [Features Currently in 3.1 Nightly · Issue #1780 · OSC/ondemand · GitHub](https://github.com/OSC/ondemand/issues/1780)

Ah, sorry for possibly unclear wording.  
I meant request of my user at my system, so it’s up to me to fix that and thanks to your hint above, I know how!
