<span class="sd"> The permissions system provides a way to assign permissions to specific</span>
<span class="sd"> users and groups of users.</span>
<span class="sd"> The permission system is used by the Django admin site, but may also be</span>
<span class="sd"> useful in your own code. The Django admin site uses permissions as follows:</span>
<span class="sd"> - The &quot;add&quot; permission limits the user&#39;s ability to view the &quot;add&quot; form</span>
<span class="sd"> and add an object.</span>
<span class="sd"> - The &quot;change&quot; permission limits a user&#39;s ability to view the change</span>
<span class="sd"> list, view the &quot;change&quot; form and change an object.</span>
<span class="sd"> - The &quot;delete&quot; permission limits the ability to delete an object.</span>
<span class="sd"> - The &quot;view&quot; permission limits the ability to view an object.</span>
<span class="sd"> Permissions are set globally per type of object, not per specific object</span>
<span class="sd"> instance. It is possible to say &quot;Mary may change news stories,&quot; but it&#39;s</span>
<span class="sd"> not currently possible to say &quot;Mary may change news stories, but only the</span>
<span class="sd"> ones she created herself&quot; or &quot;Mary may only change news stories that have a</span>
<span class="sd"> certain status or publication date.&quot;</span>
<span class="sd"> The permissions listed above are automatically created for each model.</span>

<span class="sd"> Groups are a generic way of categorizing users to apply permissions, or</span>
<span class="sd"> some other label, to those users. A user can belong to any number of</span>
<span class="sd"> groups.</span>
<span class="sd"> A user in a group automatically has all the permissions granted to that</span>
<span class="sd"> group. For example, if the group &#39;Site editors&#39; has the permission</span>
<span class="sd"> can_edit_home_page, any user in that group will have that permission.</span>
<span class="sd"> Beyond permissions, groups are a convenient way to categorize users to</span>
<span class="sd"> apply some label, or extended functionality, to them. For example, you</span>
<span class="sd"> could create a group &#39;Special users&#39;, and you could write code that would</span>
<span class="sd"> do special things to those users -- such as giving them access to a</span>
<span class="sd"> members-only portion of your site, or sending them members-only email</span>
<span class="sd"> messages.</span>
