# Version History
|
|
|
|
Superset can record the history of a chart or dashboard as you edit it, and let
|
|
you look at, restore, or branch from any earlier version.
|
|
|
|
The panel lists each saved version with its author, timestamp, and a plain
|
|
description of what changed — "Chart renamed to Q3 Revenue", "Added filter on
|
|
'Region'" — rather than a raw diff. You can search the history and filter it
|
|
down to changes on the entity itself or on the things it depends on.
|
|
|
|
## Enabling and disabling it
|
|
|
|
| Setting | Type | Effect |
|
|
| --- | --- | --- |
|
|
| `VERSION_HISTORY` | Feature flag | Shows the version history UI |
|
|
| `ENABLE_VERSIONING_CAPTURE` | Config value | Records versions as entities are saved |
|
|
|
|
Both default to on. To turn the feature off:
|
|
|
|
```python
|
|
# superset_config.py
|
|
FEATURE_FLAGS = {"VERSION_HISTORY": False}
|
|
ENABLE_VERSIONING_CAPTURE = False
|
|
```
|
|
|
|
Restart Superset and its workers for the capture change to take effect. Existing
|
|
history remains readable while capture is off, but **Restore** is unavailable
|
|
(404).
|
|
|
|
Disable them together: capture off with the UI left on gives a panel that
|
|
stops filling — an empty or stale history misrepresents the entity as
|
|
unchanged. History only accrues while capture is on; edits made while it was
|
|
off are not reconstructed.
|
|
|
|
## Viewing history
|
|
|
|
On a chart, open **… (actions) → View version history** in Explore. A dashboard
|
|
uses the same entry in its own **… (actions)** menu.
|
|
|
|
The entry appears for users who may edit the entity — the same rule the server
|
|
applies to overwriting it: administrators, plus anyone whose subjects are among
|
|
the entity's editors. Users who cannot edit do not see the panel.
|
|
|
|
## Previewing a version
|
|
|
|
Selecting a version loads it into the page so you can see it before deciding
|
|
anything. While a preview is active:
|
|
|
|
- A banner across the top marks the page as historical and names the version.
|
|
- The dashboard or chart itself is inert — filters, controls, and chart
|
|
interactions are disabled, so nothing you click can be mistaken for editing
|
|
the live entity. You can still scroll, and still move between tabs.
|
|
- Saving is unavailable. Preview never writes.
|
|
|
|
Close the preview to return to the live version, along with whatever filter
|
|
selections you had before you opened it.
|
|
|
|
A dashboard preview reconstructs the layout as it was, including charts that
|
|
have since been removed from the dashboard. A chart that has been deleted
|
|
outright cannot be reconstructed; its slot shows a placeholder instead.
|
|
|
|
Preview is a close approximation of the version, not a pixel-faithful replay.
|
|
The dashboard's own saved properties — title, CSS, metadata, description,
|
|
slug, certification, draft or published state, and theme — are shown as they
|
|
were. Charts, though, render with their current definitions rather than the
|
|
definitions they had at that version, and a dashboard's chart membership is
|
|
reconstructed from the saved layout, so charts that belonged to the dashboard
|
|
without appearing in the layout are not represented. Restore applies the full
|
|
captured state, so a restored dashboard can differ from its preview in these
|
|
respects.
|
|
|
|
## Restoring a version
|
|
|
|
**Restore** rewrites the entity back to the selected version. Two things are
|
|
worth knowing:
|
|
|
|
- **History stays append-only.** A restore is itself recorded as a new version,
|
|
so restoring never destroys the states you moved away from — you can always
|
|
restore forward again.
|
|
- **A dashboard restore may be partial.** If the version referenced charts that
|
|
have since been deleted, the layout is restored without them and Superset
|
|
tells you how many were not reattached.
|
|
|
|
Restoring is offered to the same users who may edit the entity, and is withheld
|
|
from externally managed entities, whose source of truth lives outside Superset
|
|
and would overwrite the restore on the next sync.
|
|
|
|
## Opening a version as something new
|
|
|
|
**Open as new** creates a brand-new chart or dashboard from the selected
|
|
version and leaves the original untouched. This is the safer option when you
|
|
want an old state back but are not certain you want to give up the current one.
|
|
|
|
How much of the version comes across differs by entity, because the two copy
|
|
paths do. A new chart is built from the version itself: its name,
|
|
visualization type, dataset, controls, query context, description, and cache
|
|
timeout. A new dashboard is a copy of the *live* dashboard with the version's
|
|
title, CSS, metadata, and layout applied over it — the copy endpoint accepts
|
|
only those fields, so properties such as description, slug, certification, and
|
|
theme come from the dashboard as it stands today, not from the version.
|
|
|
|
## What gets recorded
|
|
|
|
Versions capture the entity's own saved state — a chart's name, visualization
|
|
type, and controls; a dashboard's title, layout, filters, and properties.
|
|
|
|
The timeline also shows **related** activity: changes to things the entity
|
|
depends on, such as the dataset behind a chart. These are shown for context and
|
|
cannot be restored from the entity's own history — restore acts on the entity
|
|
you are looking at.
|
|
|
|
Changes made outside a save, such as ownership or permission edits, are not part
|
|
of version history.
