Checklist

Make sure these boxes are checked before submitting your issue - thank you!

• I have checked the superset logs for python stacktraces and included it here as text if there are any.
• I have reproduced the issue with at least the latest released version of superset.
• I have checked the issue tracker for the same issue and I haven’t found one similar.

Additional context

The slug is cleared on purpose, which is to avoid conflict, see https://github.com/apache/incubator-superset/blob/master/superset/models/dashboard.py#L316. But that behavior is not expected in some cases. If a dashboard is exported to a yaml and imported later, I would expect the same dashboard gets overwritten rather than creating a new dashboard with an empty slug. This is very useful when I want to create/update dashboard automatically without manual intervene. If user wants to avoid conflict, user can manually edit dashboard yaml file and set slug to null instead of hard clear in superset code.

I use a script to create the dashboard.yaml and import into superset. Without the slug, I don’t know how to reference the created dashboard in superset db.

I am having the same problem as @stuarthu. I need to automate dashboard imports but it seems impossible to do this in a consistent way due to this slug clearing.

Anyone knows a way to solve this?

the best solution I’ve foubdn so far (as of version 1.5.1) is to have an import script that roughyl does the following:

• finds target dashboard(s) to import, named by slug
• deletes any existing dashboards with that slug
• import the target dashboards
• then send a PUT to set the slug values on each
