No id and uid creates a new dashboard/folder.
No id and uid, with an existing title in folder allows overwrite
of dashboard.
Id without uid, allows update of existing dashboard/folder without
overwrite.
Uid without id allows update of existing dashboard/folder without
overwrite.
Id without uid, with an existing title in folder allows overwrite
of dashboard/folder and updated will have the uid of overwritten.
Uid without id, with an existing title in folder allows overwrite
of dashboard/folder and new will have the same uid as provided.
Trying to change an existing folder to a dashboard yields error.

* dashboards: include folder id when confirmed to save with overwrite
* dashboards: fixes due to new url structure
Return importedUrl property in response to importing dashboards and
getting plugin dashboards and use this for redirects/links in the
frontend.
Since we're already have possibility to get a dashboard by slug
it makes little sense to have a separate endpoint in api for
retrieving uid by slug.
#7883
Introduces new url in api /dashboards/<uid> for fetching dashboard by unique id
Leave the old dashboard by slug url /dashboards/db/<slug> for backward
compatibility and for supporting fallback
WIP for #7883
Instead of returning all folders a user has some sort of access to,
this change creates a new end point that returns folders the user
has write access to. This new endpoint is used in the folder picker
Breaks some stuff like selected dash in the search result.
In dashboard search, if the user is not searching then the result is
returned as a tree structure. No ACL's or user group ux yet.
A simple version control system for dashboards. Closes#1504.
Goals
1. To create a new dashboard version every time a dashboard is saved.
2. To allow users to view all versions of a given dashboard.
3. To allow users to rollback to a previous version of a dashboard.
4. To allow users to compare two versions of a dashboard.
Usage
Navigate to a dashboard, and click the settings cog. From there, click
the "Changelog" button to be brought to the Changelog view. In this
view, a table containing each version of a dashboard can be seen. Each
entry in the table represents a dashboard version. A selectable
checkbox, the version number, date created, name of the user who created
that version, and commit message is shown in the table, along with a
button that allows a user to restore to a previous version of that
dashboard. If a user wants to restore to a previous version of their
dashboard, they can do so by clicking the previously mentioned button.
If a user wants to compare two different versions of a dashboard, they
can do so by clicking the checkbox of two different dashboard versions,
then clicking the "Compare versions" button located below the dashboard.
From there, the user is brought to a view showing a summary of the
dashboard differences. Each summarized change contains a link that can
be clicked to take the user a JSON diff highlighting the changes line by
line.
Overview of Changes
Backend Changes
- A `dashboard_version` table was created to store each dashboard
version, along with a dashboard version model and structs to represent
the queries and commands necessary for the dashboard version API
methods.
- API endpoints were created to support working with dashboard
versions.
- Methods were added to create, update, read, and destroy dashboard
versions in the database.
- Logic was added to compute the diff between two versions, and
display it to the user.
- The dashboard migration logic was updated to save a "Version
1" of each existing dashboard in the database.
Frontend Changes
- New views
- Methods to pull JSON and HTML from endpoints
New API Endpoints
Each endpoint requires the authorization header to be sent in
the format,
```
Authorization: Bearer <jwt>
```
where `<jwt>` is a JSON web token obtained from the Grafana
admin panel.
`GET "/api/dashboards/db/:dashboardId/versions?orderBy=<string>&limit=<int>&start=<int>"`
Get all dashboard versions for the given dashboard ID. Accepts
three URL parameters:
- `orderBy` String to order the results by. Possible values
are `version`, `created`, `created_by`, `message`. Default
is `versions`. Ordering is always in descending order.
- `limit` Maximum number of results to return
- `start` Position in results to start from
`GET "/api/dashboards/db/:dashboardId/versions/:id"`
Get an individual dashboard version by ID, for the given
dashboard ID.
`POST "/api/dashboards/db/:dashboardId/restore"`
Restore to the given dashboard version. Post body is of
content-type `application/json`, and must contain.
```json
{
"dashboardId": <int>,
"version": <int>
}
```
`GET "/api/dashboards/db/:dashboardId/compare/:versionA...:versionB"`
Compare two dashboard versions by ID for the given
dashboard ID, returning a JSON delta formatted
representation of the diff. The URL format follows
what GitHub does. For example, visiting
[/api/dashboards/db/18/compare/22...33](http://ec2-54-80-139-44.compute-1.amazonaws.com:3000/api/dashboards/db/18/compare/22...33)
will return the diff between versions 22 and 33 for
the dashboard ID 18.
Dependencies Added
- The Go package [gojsondiff](https://github.com/yudai/gojsondiff)
was added and vendored.
