How do I install Ninja Content?

Ninja Content and all it’s dependencies is installed in the same way as all other Joomla! extensions. Simply log in to the administrator panel and install in the usual manner.

How do I restrict what users can do?

Ninja Content works on a permissions set per usergroup basis, in order to restrict the actions a particular group has access to you need to edit the permission set for that group or alternatively add a new permission set for that group, if one does not already exist.

[ Joomla! Admin >> Components >> Ninja Content >> Permissions ]

The permission edit screen has a variety of options for restricting what a usergroup can do, these options are out of the scope of this FAQ. Don’t fear however, it comes with helpful tooltips that explain what each option does, simply hover over the options label for the tooltip to popup.

Note: Super Administrators cannot be restricted in anyway. They quite rightly have access to do everything.

How do I add/edit permission sets?

Adding and Editing new permission sets couldn’t be easier. Simply navigate to the permissions screen in the Ninja Content backend and hit the [Add] button or select the permission set you wish to edit and hit the [Edit] button. Once you have finished setting up your permissions, hit the [Save] button and your permission set is saved

[ Joomla! Admin >> Components >> Ninja Content >> Permissions ]

Can I have different permissions on a per menu item basis?

Yes you can and its very easy to accomplish. First of all you should make sure that you have set up default permission sets for all the usergroups who need access to Ninja Content.

Next simply create a menu item for Ninja Content in your chosen menu as you would normally.

[ Joomla! Admin >> Menus >> Chosen Menu >> New >> NinjaContent ]

You will notice on the right hand side of the screen a list of permission parameters that you can override. First select the permission sets that you wish to override. Next change any of the settings you wish to override for these usergroups.

Simply leave the options as “Use Default” if you want that permission to be handled by the usergroups permissions set.

Finally just save the menu item and your overrides will be activated for that menu only.

Frequently Asked Questions

Why don't my changes to permissions show on the frontend?
There can be a number of reasons that permissions appear not to be working on the frontend. Please check the following:

  • That you have selected the correct usergroup in the permission set.
  • That the permission set is published (unpublished permissions will not work).
  • That you do not have permission overrides in the menu item.
  • That you do not have more than one permission set for the usergroup.
  • That you are not logged in as a ‘Super Administrator’, this usergroup cannot be restricted.
Does Ninja Content have a Content Versioning (Revisions) feature?

Early versions of Ninja Content did indeed have revisions, but this was removed in version 1.5.
Revisions may make a comeback in future versions of Ninja Content, but there are no immediate plans to re-implement the feature.

If you need versioning, you can use Simple Content Versioning, which works well with Ninja Content.

Can I manage modules and menus with Ninja Content?

Unfortunately not; Ninja Content only allows you to manage your Joomla articles.

Can I customize the article submission settings per user?

Ninja Content doesn't allow you to assign permissions and settings to individual users, so this is not possible to do "out of the box". However, there is a workaround that might work for you.

Ninja Content only allows you to assign settings/permissions to User Groups, so the workaround is to create a new group for each user and give that the group the custom settings/permissions you want the user to have.

To do that, you need to use an extension that allows you to create groups. We've gotten feedback suggesting that the following extensions work fine with Ninja Content, but other User Group extensions may also do the job.

When installing Ninja Content the installation hangs on 'Please wait, checking for additional packages...'
Ninja Content uses javascript in its installation script, there are 2 known 3rd Party extensions that can cause the installer to break:

  • Jomsocial System plugin
  • Javascript SDK System plugin

Please temporarily unpublish the system plugin and try the installation again. When the installation has completed you can re-publish the system plugin.

If you are not using any of the above extensions, or this solution does not resolve the problem, please post in our forums for help.
