如何在Odoo环境中将所有缓存写入数据库？

Question

I'm doing a test where I need to imitate the onchange behavior, so:

with self.env.do_in_onchange():
    self.onefield = "blahblah"

But when one exits the with block, that data is not written to DB. I'm looking for some kind of self.env.cache.write_to_db() . Do you know of any?

I found the solution.

To write a record's cache:

self.write(self._convert_to_write(self._cache))

To write all the environment's cache:

models = dict()
for field, cache in self.env.cache.iteritems():
    for id_, value in cache.iteritems():
        models.setdefault(field.model_name, list())
        models[field.model_name].append(id_)

for name, ids in models.iteritems():
    for record in self.env[name].browse(ids):
        record.write(record._convert_to_write(record._cache))
