158 """ New-style configuration base specialized for addons selection
164 Subclasses can simply define a number of _columns as
165 fields.boolean objects. The keys (column names) should be the
166 names of the addons to install (when selected). Upon action
167 execution, selected boolean fields (and those only) will be
168 interpreted as addons to install, and batch-installed.
173 It is also possible to require the installation of an additional
174 addon set when a specific preset of addons has been marked for
175 installation (in the basic usage only, additionals can't depend on
178 These additionals are defined through the ``_install_if``
179 property. This property is a mapping of a collection of addons (by
180 name) to a collection of addons (by name) [#]_, and if all the *key*
181 addons are selected for installation, then the *value* ones will
182 be selected as well. For example::
185 ('sale','crm'): ['sale_crm'],
188 This will install the ``sale_crm`` addon if and only if both the
189 ``sale`` and ``crm`` addons are selected for installation.
191 You can define as many additionals as you wish, and additionals
192 can overlap in key and value. For instance::
195 ('sale','crm'): ['sale_crm'],
196 ('sale','project'): ['project_mrp'],
199 will install both ``sale_crm`` and ``project_mrp`` if all of
200 ``sale``, ``crm`` and ``project`` are selected for installation.
205 Subclasses might also need to express dependencies more complex
206 than that provided by additionals. In this case, it's possible to
207 define methods of the form ``_if_%(name)s`` where ``name`` is the
208 name of a boolean field. If the field is selected, then the
209 corresponding module will be marked for installation *and* the
210 hook method will be executed.
212 Hook methods take the usual set of parameters (cr, uid, ids,
213 context) and can return a collection of additional addons to
214 install (if they return anything, otherwise they should not return
215 anything, though returning any "falsy" value such as None or an
216 empty collection will have the same effect).
221 The last hook is to simply overload the ``modules_to_install``
222 method, which implements all the mechanisms above. This method
223 takes the usual set of parameters (cr, uid, ids, context) and
224 returns a ``set`` of addons to install (addons selected by the
225 above methods minus addons from the *basic* set which are already
226 installed) [#]_ so an overloader can simply manipulate the ``set``
227 returned by ``res_config_installer.modules_to_install`` to add or
230 Skipping the installer
231 ----------------------
233 Unless it is removed from the view, installers have a *skip*
234 button which invokes ``action_skip`` (and the ``cancel`` hook from
235 ``res.config``). Hooks and additionals *are not run* when skipping
236 installation, even for already installed addons.
238 Again, setup your hooks accordingly.
240 .. [#] note that since a mapping key needs to be hashable, it's
241 possible to use a tuple or a frozenset, but not a list or a
244 .. [#] because the already-installed modules are only pruned at
245 the very end of ``modules_to_install``, additionals and
246 hooks depending on them *are guaranteed to execute*. Setup
247 your hooks accordingly.
