Moodle plugin which programatically restores courses to predefined course states. It can be used to provide playground moodle courses which will be cleaned periodically
This plugin requires Moodle 3.2+
Providing sandbox courses to your users makes sense for simplifying live training courses or for letting new Moodle users explore the features of Moodle. However, manually resetting sandbox courses after a live training session or after a certain amount of time is a daunting task.
If you want to get rid of this senseless job of resetting courses periodically manually, this plugin is for you.
Install the plugin like any other plugin to folder /local/sandbox
See http://docs.moodle.org/en/Installing_plugins for details on installing Moodle plugins
After installing the plugin, it does not do anything to Moodle yet.
To configure the plugin and its behaviour, please visit: Site administration -> Courses -> Sandbox.
There, you find three sections:
Moodle core supports a system called "Scheduled tasks". The execution time settings of the sandbox plugin is configured in the "Scheduled tasks" system.
By default, sandbox's scheduled task is disabled in the "Scheduled tasks" system. You have to enable it there to make use of this plugin.
By default, sandbox's scheduled task is set to run every sunday on 1:00 GMT in the "Scheduled tasks" system. Please change this time according to your needs.
In this section, you define the directory where the course backup files to use for course restoring are. local_sandbox takes every file in this directory with a .mbz filename extension, takes the file's name, searches for a existing course with a shortname equal to the file's name and finally, uses the course backup file to restore / reset this course.
Example: The sandbox directory /var/www/files/moodledata/sandbox contains the files foo.bar and mylittlecourse.mbz. local_sandbox looks at the directory and finds two files. File foo.bar is ignored by local_sandbox because it doesn't have the right filename extension. File mylittlecourse.mbz will be considered for restoring a sandbox course. local_sandbox now looks for a existing course with shortname "mylittlecourse". If this course exists, it resets / restores it to the state saved in the mylittlecourse.mbz backup file. If this course doesn't exist, local_sandbox doesn't change anything.
Additionally, in this section, there is an option to set the course start date to today instead of setting it to the date saved in the course backup file. Use this option if you need to provide playground courses in Moodle which pretend to be up-to-date.
As local_sandbox acts automatically, it can inform you when failures or problems occur. In this section, you can define who should be notified and which failures or problems should be reported.
If you have debugging enabled in your Moodle installation, as soon as local_sandbox is configured and working, there might be an email sent to the webserver administrator (the person who gets stdout output from unix cronjobs) telling something like this:
instantiating restore controller 0b3123770cffd351d7c7b890a7a0035c

This output is generated by the restore controller used by local_sandbox and can't be suppressed according to our knowledge. You can simply delete these mails.
The plugin's description states that it restores courses to predefined course states. In reality, this is not exactly true. In fact, the plugin operates by completely deleting a course and creating a new one from the configured backup file.
Normally, this tiny detail is unimportant. However, you should know that each resetted course gets a new course ID. This can produce problems if you have a hardcoded link (from outside or inside of Moodle) pointing to a sandbox course. This link will break with each run of the sandbox plugin. If you want to have a hardcoded link to a sandbox course, please construct the link's URL like https://<YOURMOODLE>/course/view.php?name=<COURSE-SHORTNAME> instead of https://<YOURMOODLE>/course/view.php?id=<COURSE-ID>.
This plugin acts behind the scenes, therefore it should work with all Moodle themes. It has been developed on and tested with Moodle Core's Clean and Boost themes.
This plugin is published and regularly updated in the Moodle plugins repository: http://moodle.org/plugins/view/local_sandbox
The latest development version can be found on Github: https://github.com/moodleuulm/moodle-local_sandbox
This plugin is carefully developed and thoroughly tested, but bugs and problems can always appear.
Please report bugs and problems on Github: https://github.com/moodleuulm/moodle-local_sandbox/issues
We will do our best to solve your problems, but please note that due to limited resources we can't always provide per-case support.
Due to limited resources, the functionality of this plugin is primarily implemented for our own local needs and published as-is to the community. We are aware that members of the community will have other needs and would love to see them solved by this plugin.
Please issue feature proposals on Github: https://github.com/moodleuulm/moodle-local_sandbox/issues
Please create pull requests on Github: https://github.com/moodleuulm/moodle-local_sandbox/pulls
We are always interested to read about your feature proposals or even get a pull request from you, but please accept that we can handle your issues only as feature proposals and not as feature requests.
Due to limited resources, this plugin is only maintained for the most recent major release of Moodle. However, previous versions of this plugin which work in legacy major releases of Moodle are still available as-is without any further updates in the Moodle Plugins repository.
There may be several weeks after a new major release of Moodle has been published until we can do a compatibility check and fix problems if necessary. If you encounter problems with a new major release of Moodle - or can confirm that this plugin still works with a new major relase - please let us know on Github.
If you are running a legacy version of Moodle, but want or need to run the latest version of this plugin, you can get the latest version of the plugin, remove the line starting with $plugin->requires from version.php and use this latest plugin version then on your legacy Moodle. However, please note that you will run this setup completely at your own risk. We can't support this approach in any way and there is a undeniable risk for erratic behavior.
This Moodle plugin is shipped with an english language pack only. All translations into other languages must be managed through AMOS (https://lang.moodle.org) by what they will become part of Moodle's official language pack.
As the plugin creator, we manage the translation into german for our own local needs on AMOS. Please contribute your translation into all other languages in AMOS where they will be reviewed by the official language pack maintainers for Moodle.
This plugin has not been tested with Moodle's support for right-to-left (RTL) languages. If you want to use this plugin with a RTL language and it doesn't work as-is, you are free to send us a pull request on Github with modifications.
Since Moodle 3.0, Moodle core basically supports PHP7. Please note that PHP7 support is on our roadmap for this plugin, but it has not yet been thoroughly tested for PHP7 support and we are still running it in production on PHP5. If you encounter any success or failure with this plugin and PHP7, please let us know.
