odoo每次启动的时候都会加载模块加载模块的过程就是调用load_modules 函数
在函数位于 odoo\modules\loading.py
代码中注释也写的很清楚共分了9个步骤其实是8个步骤。
这个函数的作用是为一个新创建的注册表对象加载模块这是Registry.new()的一部分不应该用在其他地方。

0、初始化数据库
这里判断数据库有没有被初始化如果没有就安装base模块 initialize_sys_path()force []if force_demo:force.append(demo)models_to_check set()with registry.cursor() as cr:# prevent endless wait for locks on schema changes (during online# installs) if a concurrent transaction has accessed the table;# connection settings are automatically reset when the connection is# borrowed from the poolcr.execute(SET SESSION lock_timeout 15s)if not odoo.modules.db.is_initialized(cr):if not update_module:_logger.error(Database %s not initialized, you can force it with -i base, cr.dbname)return_logger.info(init db)odoo.modules.db.initialize(cr)update_module True # process auto-installed modulestools.config[init][all] 1if not tools.config[without_demo]:tools.config[demo][all] 1if base in tools.config[update] or all in tools.config[update]:cr.execute(update ir_module_module set state%s where name%s and state%s, (to upgrade, base, installed))
step 1、加载base模块
第一步就是加载base模块 最后还加载了其他模块的语言包
SELECT model || . || name FROM ir_model_fields WHERE translate IS TRUE #原来pg使用|| 来拼接字符串的。registry._database_translated_fields {row[0] for row in cr.fetchall()} # 这个写法也很有意思简洁# STEP 1: LOAD BASE (must be done before module dependencies can be computed for later steps)graph odoo.modules.graph.Graph()graph.add_module(cr, base, force)if not graph:_logger.critical(module base cannot be loaded! (hint: verify addons-path))raise ImportError(Module base cannot be loaded! (hint: verify addons-path))if update_module and odoo.tools.table_exists(cr, ir_model_fields):# determine the fields which are currently translated in the databasecr.execute(SELECT model || . || name FROM ir_model_fields WHERE translate IS TRUE)registry._database_translated_fields {row[0] for row in cr.fetchall()} # processed_modules: for cleanup step after install# loaded_modules: to avoid double loadingreport registry._assertion_reportloaded_modules, processed_modules load_module_graph(cr, graph, status, perform_checksupdate_module,reportreport, models_to_checkmodels_to_check)load_lang tools.config.pop(load_language)if load_lang or update_module:# some base models are used below, so make sure they are set upregistry.setup_models(cr)if load_lang:for lang in load_lang.split(,):tools.load_language(cr, lang)控制台输出

step 3、加载除了base之外的其他模块
1、分两个步骤完成第一步加载所有已经安装的或者部分安装需要升级为第二步提供一个一致性的系统。第二步是安装新的模块。
我们在第一步中考虑了to_remove 的模块因为他们是“已安装”模块的一部分 他们将在step 6 去处理。
2、这里不得不循环处理因为要处理模块之间的依赖关系

step 4、完成并且清理安装过程
基本就是一些善后过程正常情况下不会执行

step 5、卸载相关模块
SELECT name, id FROM ir_module_module WHERE state%s, (to remove,)如果配置了uninstall_hook要在这里执行。 然后调用module_uninstall方法来卸载
Module.browse(modules_to_remove.values()).module_uninstall()卸载完成之后刷新注册表。
5.5 是要处理一些模型之间的依赖关系。
# STEP 5: Uninstall modules to removeif update_module:# Remove records referenced from ir_model_data for modules to be# removed (and removed the references from ir_model_data).cr.execute(SELECT name, id FROM ir_module_module WHERE state%s, (to remove,))modules_to_remove dict(cr.fetchall())if modules_to_remove:env api.Environment(cr, SUPERUSER_ID, {})pkgs reversed([p for p in graph if p.name in modules_to_remove])for pkg in pkgs:uninstall_hook pkg.info.get(uninstall_hook)if uninstall_hook:py_module sys.modules[odoo.addons.%s % (pkg.name,)]getattr(py_module, uninstall_hook)(cr, registry)env.flush_all()Module env[ir.module.module]Module.browse(modules_to_remove.values()).module_uninstall()# Recursive reload, should only happen once, because there should be no# modules to remove next timecr.commit()_logger.info(Reloading registry once more after uninstalling modules)registry odoo.modules.registry.Registry.new(cr.dbname, force_demo, status, update_module)cr.reset()registry.check_tables_exist(cr)cr.commit()return registry# STEP 5.5: Verify extended fields on every model# This will fix the schema of all models in a situation such as:# - module A is loaded and defines model M;# - module B is installed/upgraded and extends model M;# - module C is loaded and extends model M;# - module B and C depend on A but not on each other;# The changes introduced by module C are not taken into account by the upgrade of B.if models_to_check:registry.init_models(cr, list(models_to_check), {models_to_check: True})step 6、确认每个模型相关的视图 # STEP 6: verify custom views on every modelif update_module:env api.Environment(cr, SUPERUSER_ID, {})env[res.groups]._update_user_groups_view()View env[ir.ui.view]for model in registry:try:View._validate_custom_views(model)except Exception as e:_logger.warning(invalid custom view(s) for model %s: %s, model, tools.ustr(e))if report.wasSuccessful():_logger.info(Modules loaded.)else:_logger.error(At least one test failed when loading the modules.)控制台输出

可以在模块加载完之后动态修改模型的一些属性值。
比如修改_rec_name
def _register_hook(self):setattr(type(self),_rec_name, myname)安装模块的时候也会执行load_modules函数重新加载所有的模块如果你希望你的逻辑只有在启动的时候执行而不是安装模块的时候执行在context中有个变量可以区分。
哪个变量
