1、tree field 属性中 为什么获取不到uid
根据之前分析的代码。知道 load_view 里面会解析field属性的
def transfer_node_to_modifiers(node, modifiers, context=None, in_tree_view=False):
if node.get('attrs'):
#If you want, add more conditions here
if ', uid' in node.get('attrs'):
#这里的uid 是自己加的。这样才可以处理
user_id = str(context.get('uid', 1))
user_id = ', ' + user_id
attrs = node.get('attrs')
attrs = attrs.replace(', uid', user_id)
node.set('attrs', attrs)
modifiers.update(eval(node.get('attrs')))
if node.get('states'):
if 'invisible' in modifiers and isinstance(modifiers['invisible'], list):
# TODO combine with AND or OR, use implicit AND for now.
modifiers['invisible'].append(('state', 'not in', node.get('states').split(',')))
else:
modifiers['invisible'] = [('state', 'not in', node.get('states').split(','))]
for a in ('invisible', 'readonly', 'required'):
if node.get(a):
v = bool(eval(node.get(a), {'context': context or {}}))
if in_tree_view and a == 'invisible':
# Invisible in a tree view has a specific meaning, make it a
# new key in the modifiers attribute.
modifiers['tree_invisible'] = v
elif v or (a not in modifiers or not isinstance(modifiers[a], list)):
# Don't set the attribute to False if a dynamic value was
# provided (i.e. a domain from attrs or states).
modifiers[a] = v
因为 attrs 中根本没处理 uid
2、domain_force 为何可以用 user 而 domain中不可以写
因为 domain_force 是rule中的字段。
def _eval_context(self):
"""Returns a dictionary to use as evaluation context for
ir.rule domains."""
# use an empty context for 'user' to make the domain evaluation
# independent from the context
return {'user': self.env.user.with_context({}), 'time': time}
eval_context 就是 {'user':obj} ,作为参数传入,肯定就可以用user了
dom = safe_eval(rule.domain_force, eval_context) if rule.domain_force else []
dom = expression.normalize_domain(dom)
而domain 是用 self.env.context 只有uid 做参数
可不可以 用 什么属性。主要看eval 后面给什么参数
