<h1>Overrides</h1>
|
|
|
|
<p>
|
|
Overrides are specific permissions designed to override a
|
|
role in a specific context, allowing you to "tweak" your
|
|
permissions as required.
|
|
</p>
|
|
|
|
<p>
|
|
For example, if users with the role Student in your course
|
|
can usually start new discussions in forums, but there is
|
|
one particular forum for which you want to restrict that
|
|
capability, then you can set an override that PREVENTS
|
|
the capability for Students to "Start new discussions".
|
|
</p>
|
|
|
|
<p>
|
|
Overrides can also be used to "open up" areas of your
|
|
site and courses to give users extra permissions where
|
|
it makes sense. For example, you may want to experiment
|
|
giving Students the ability to grade some assignments.
|
|
</p>
|
|
|
|

|
|
The interface is similar to the one for defining roles,
|
|
except sometimes only relevant capabilities are shown,
|
|
and you will also see some capabilities highlighted to
|
|
show you what the permission for that role would be
|
|
WITHOUT any override active (ie when your override is
|
|
set to INHERIT).
