To avoid complications with how Google Auth works, when enabling organization
multi-tenancy on a single instance, each organization becomes a "sub folder"
instead of a sub-domain.
This is one huge change for the permissions system and related:
* (Backward incompatible:) Remove the table based permissions in favour of the new model.
* Manage permission to view or query datasources based on groups.
* Add the concept of Organization. It's irrelevant for most deployments, but allows for
multi-tenant support in re:dash.
* Replace ActivityLog with Event based rows (old data in activity_log table is retained).
* Enforce permissions on the server-side. There were some permissions that were only enforced
on the client side. This is no more. All permissions are enforced by the server.
* Added new permission: 'super-admin' to access the status and Flask-Admin interface.
* Make sure that html is never cached by the browser - this is to make sure that the browser
will always ask for the new Javascript/CSS resources (if such are available).
1. Load all date/datetime values with moment.utc() which doesn't apply
current timezone to them.
2. Don't use toLocaleString to format strings (which was converting them
to current timezone as well).
Ref #411.
* Web interface to add and delete data sources, without the need to ssh
into the server.
* Ability to safely delete datasources -- query results from this data sources
are deleted, while queries get assigned null datasource.
* Updated the BigQuery datasource to use the JSON key file from Google Developer
console. Also both BigQuery and the Google Spreadsheets datasource no longer store
their key on the filesystem, but rather in the DB.
* Minor updates to the Flask Admin.
This is basic implementation for alerts feature, where you can
define a simple rule on the last query result to send an alert.
As part of the implementation added Flask-Mail to the project,
to send emails. Should be useful to make re:dash more "self aware"
(notify users about potential issues, when queries done executing
and more).
- Improved error handling to show the real error (including indentation and syntax errors - it should show the right row number)
- Added support for "print" statements which becomes log messages show in a single query window (where you edit). It's on by default. To remove it simply called 'disable_print_log()'
