Trigger form can be called via URL with fields pre-populated.

What happened?

In Airflow 2.7++ it was possible to directly call the trigger form UI via a URL and with URL parameters also to pre-populate fields.

This feature is missing in Airflow 3 UI - and would be great to add it back again.

What you think should happen instead?

If you call http://localhost:28080/dags/example_params_ui_tutorial you can open the Dag directly.

Target would be to be able to call http://localhost:28080/dags/example_params_ui_tutorial/trigger (or similar) to directly open the trigger form when page is opened. If parameters in for key=value are passed, these are pre-filling the form data.

With this feature restored the documentation cleanup from https://github.com/apache/airflow/pull/54799 could be reversed as well

Hi, I just wanted to mention that it might take me quite a bit of time to complete this issue. Since there’s already a PR opened for it, I fully support that and I think it would be best to move forward with their solution. Please feel free to accept their PR.

Thanks!

@Thanush-03 and @viiccwen as you are both on a PR, both feel a bit stale. Still working on it or should we give somebody else the opportunity to complete?
