[hooks/security] provide attribute "add" permission
As of today, the update permission on attributes is checked at entity
*creation* time. This forbids using update permissions the proper way.
We set it to be checked at entity update time only.
We introduce a specific 'add' permission rule for attributes.
For backward compatibility, its default value will be the same as the
current 'update' permission.
Notes:
* needs a new yams version (ticket #149216)
* introduces two new 'add_permissions' rdefs (attribute - group|rqlexpr)
* if the update permission was () and the bw compat kicks in, the rule
is not enforced, to avoid un-creatable entity types -- this
restriction will be lifted when the bw compat is gone
* small internal refactoring on check_entity_attributes
* one small pre 3.6.1 bw compat snippet must be removed from schemaserial
Closes #2965518.
Once you have read the `RQL tutorial`_ and you know the application'`schema`_,
you're ready to define your own views. Just type the RQL query retreiving data
you're interested in in the search field. If the view used to display them
doesn't fit your need, choose another one in the possible views box (this box
isn't displayed by default, but you can activate it in your `user
preferences`_). Once you're satified, add a `bookmark`_ if you want to reuse
this view later.
.. _`RQL tutorial`: doc/tut_rql
.. _`schema`: schema
.. _`user preferences`: myprefs
.. _`bookmark`: doc/bookmarks
Below are some example of what can be acheived...
