class ResConfigInstaller(models.TransientModel, ResConfigModuleInstallationMixin):
""" New-style configuration base specialized for addons selection
and installation.
Basic usage
-----------
Subclasses can simply define a number of boolean fields. The field names
should be the names of the addons to install (when selected). Upon action
execution, selected boolean fields (and those only) will be interpreted as
addons to install, and batch-installed.
Additional addons
-----------------
It is also possible to require the installation of an additional
addon set when a specific preset of addons has been marked for
installation (in the basic usage only, additionals can't depend on
one another).
These additionals are defined through the ``_install_if``
property. This property is a mapping of a collection of addons (by
name) to a collection of addons (by name) [#]_, and if all the *key*
addons are selected for installation, then the *value* ones will
be selected as well. For example::
_install_if = {
('sale','crm'): ['sale_crm'],
}
This will install the ``sale_crm`` addon if and only if both the
``sale`` and ``crm`` addons are selected for installation.
You can define as many additionals as you wish, and additionals
can overlap in key and value. For instance::
_install_if = {
('sale','crm'): ['sale_crm'],
('sale','project'): ['sale_service'],
}
will install both ``sale_crm`` and ``sale_service`` if all of
``sale``, ``crm`` and ``project`` are selected for installation.
Hook methods
------------
Subclasses might also need to express dependencies more complex
than that provided by additionals. In this case, it's possible to
define methods of the form ``_if_%(name)s`` where ``name`` is the
name of a boolean field. If the field is selected, then the
corresponding module will be marked for installation *and* the
hook method will be executed.
Hook methods take the usual set of parameters (cr, uid, ids,
context) and can return a collection of additional addons to
install (if they return anything, otherwise they should not return
anything, though returning any "falsy" value such as None or an
empty collection will have the same effect).
Complete control
----------------
The last hook is to simply overload the ``modules_to_install``
method, which implements all the mechanisms above. This method
takes the usual set of parameters (cr, uid, ids, context) and
returns a ``set`` of addons to install (addons selected by the
above methods minus addons from the *basic* set which are already
installed) [#]_ so an overloader can simply manipulate the ``set``
returned by ``ResConfigInstaller.modules_to_install`` to add or
remove addons.
Skipping the installer
----------------------
Unless it is removed from the view, installers have a *skip*
button which invokes ``action_skip`` (and the ``cancel`` hook from
``res.config``). Hooks and additionals *are not run* when skipping
installation, even for already installed addons.
Again, setup your hooks accordingly.
.. [#] note that since a mapping key needs to be hashable, it's
possible to use a tuple or a frozenset, but not a list or a
regular set
.. [#] because the already-installed modules are only pruned at
the very end of ``modules_to_install``, additionals and
hooks depending on them *are guaranteed to execute*. Setup
your hooks accordingly.

* For a boolean field like 'group_XXX', ``execute`` adds/removes 'implied_group'
to/from the implied groups of 'group', depending on the field's value.
By default 'group' is the group Employee. Groups are given by their xml id.
The attribute 'group' may contain several xml ids, separated by commas.
* For a selection field like 'group_XXX' composed of 2 integers values ('0' and '1'),
``execute`` adds/removes 'implied_group' to/from the implied groups of 'group',
depending on the field's value.
By default 'group' is the group Employee. Groups are given by their xml id.
The attribute 'group' may contain several xml ids, separated by commas.
* For a boolean field like 'module_XXX', ``execute`` triggers the immediate
installation of the module named 'XXX' if the field has value ``True``.
* For a selection field like 'module_XXX' composed of 2 integers values ('0' and '1'),
``execute`` triggers the immediate installation of the module named 'XXX'
if the field has the integer value ``1``.
* For the other fields, the method ``execute`` invokes all methods with a name
that starts with 'set_'; such methods can be defined to implement the effect
of those fields.
The method ``default_get`` retrieves values that reflect the current status of the
fields like 'default_XXX', 'group_XXX' and 'module_XXX'. It also invokes all methods

current values for other fields.
