Experimental type-filters-flow visualization

[tcompa]

Backend branch: 2194-prepare-a-view-of-the-flow-of-type-filters-within-a-workflow
PR: https://github.com/fractal-analytics-platform/fractal-server/pull/2197/files

Known: project_id and workflow_id

Dropdown menus for

• dataset (optional)
• first task index (optional)
• last task index (optional)

Endpoint:

GET http://localhost:8000/api/v2/project/1/workflow/1/type-filters-flow/

with

• optional query parameters: dataset_id, first_task_index, `last_task_index

Response schema

class TypeFiltersFlow(BaseModel):
    dataset_filters: list[dict[str, bool]]
    input_filters: list[dict[str, bool]]
    output_filters: list[dict[str, bool]]

where I/O filters lists have length N=(number of tasks) and dataset_filters has length N+1.

Where to show this new information: a new "Type filters flow" (TBD) modal, accessible from the workflow page.

Basic option for how to display: a five-columns table

• workflowtask.task.name
• dataset_filters[ind]
• input_filters[ind]
• output_filters[ind]
• dataset_filters[ind+1]

Here are some examples based on another workflow.

When planning to run for the first time

When planning to re-run the whole workflow (note that this would not be a good workflow to re-run, as it would restart from conversion)

When planning to re-run only a part of the workflow

When planning to run on a different (fake) dataset

1. Let's keep the modal, and hide the button for non-superuser users
2. Let's add a "type" dropdown menu, populated with all types that enter the data. Selecting e.g. is_3D means that only this type filters are considered.
3. Let's move to three columns: Task, Pre, Post (names TBD)

This goes in the direction of what we discussed this afternoon (i.e. showing transitions, rather than state), but it's still to be considered preliminary because not all rows may have values set. More iterations on this page will come in future versions, after we test this visualization on some realistic workflows.

Re: single-type-filter selection
Great, thanks.

Re: columns
Sorry for backtracking, but this looks a bit different from what I expected.. I'd say let's switch back to four columns (Pre/Input/Output/Post). At least we'll have a complete view (even though it's not immediately transparent), and we'll build from there.
