Basic usage ----------- Subclasses can simply define a number of _columns as fields.boolean objects. The keys (column 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'): ['project_mrp'], } will install both ``sale_crm`` and ``project_mrp`` 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 ``res_config_installer.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.
