Configuration values¶

The following are the configuration variables of weblablib:

WebLab-Deusto¶

`WEBLAB_USERNAME`	WebLab-Deusto credentials. It is not the username of the new user: it represents the system itself (e.g., the WebLab-Deusto system calling). Mandatory
`WEBLAB_PASSWORD`	WebLab-Deusto credentials. Read also `WEBLAB_USERNAME`. Mandatory
`WEBLAB_POLL_INTERVAL`	WebLab-Deusto is connecting every few seconds to the laboratory asking if the user is still alive or if he left. By default, 5 seconds. You can regulate it with this configuration variable. Note that if you establish `0`, then WebLab-Deusto will not ask again and will wait until the end of the cycle.

`WEBLAB_CALLBACK_URL`	weblablib creates a set or URLs for receiving methods directly by the user. This methods must be publicly available by the student. It can be `/mylab/callback`.
`WEBLAB_BASE_URL`	If you want to start /weblab/sessions somewhere else (e.g., `/mylab`), you can configure it here.
`WEBLAB_SCHEME`	If set to `https`, forces using `https` in the link sent to the user.

`WEBLAB_REDIS_URL`	Url used for connecting to Redis. By default it’s the database 0 with localhost and standard port, but you can configure it: `redis://localhost:6379/`.
`WEBLAB_REDIS_BASE`	If you use multiple laboratories in the same server, you should give different values to this configuration so there is no conflict in Redis. If one is `lab1` and the other is `lab2`, in Redis values will start by `lab1:` or `lab2:`.

`WEBLAB_SESSION_ID_NAME`	The name that the weblablib session will have in the Flask session object.
`WEBLAB_TIMEOUT`	Value in seconds taken by weblablib to consider a user expired if s/he hasn’t polled in this time.
`WEBLAB_AUTOPOLL`	If `True` (default value), it will make that every call to the server will call `poll`.
`WEBLAB_EXPIRED_USERS_TIMEOUT`	Once the user is expired, the information is kept in Redis for some time. By default, this is `3600` (seconds, which is one hour).
`WEBLAB_UNAUTHORIZED_LINK`	When a user is not logged in (or the session expired -after an hour-, by default finds an `Access forbidden` message. You can put a link here to redirect him to a different URL (such as your WebLab-Deusto system, so the student is forced to log in).
`WEBLAB_UNAUTHORIZED_TEMPLATE`	Same as `WEBLAB_UNAUTHORIZED_LINK`, but instead of redirecting, it renders a template. If you put `forbidden.html`, it will render whatever is in `templates/forbidden.html`.

`WEBLAB_AUTOCLEAN_THREAD`	By default `True`, it states whether there will be a thread by process cleaning sessions of expired users or not.
`WEBLAB_TASK_THREADS_PROCESS`	By default `3`, it is the number of threads in each weblablib process running tasks submitted by user.
`WEBLAB_NO_THREAD`	Equivalent to `WEBLAB_AUTOCLEAN_THREAD=False` and `WEBLAB_TASK_THREADS_PROCESS=0`. If you use it, make sure you run `flask loop`
