odoo 12.0 track_visibility = 'always' 无效

• 原因

  • odoo12.0 对属性track_visibility 只做了非False判断, 也就是说track_visibility 属性不写False, 或者不定义这个属性,其他都为onchange
    • if getattr(field, 'track_visibility', False):

• 解决方法修改addons/mail/models/mail_thread.py的_message_track方法为

def _message_track(self, tracked_fields, initial):
    """ For a given record, fields to check (tuple column name, column info)
    and initial values, return a structure that is a tuple containing :

        - a set of updated column names
        - a list of changes (initial value, new value, column name, column info) """
    self.ensure_one()
    changes = set()  # contains always and onchange tracked fields that changed
    displays = set()  # contains always tracked field that did not change but displayed for information
    tracking_value_ids = []
    display_values_ids = []

    # generate tracked_values data structure: {'col_name': {col_info, new_value, old_value}}
    for col_name, col_info in tracked_fields.items():
        track_visibility = getattr(self._fields[col_name], 'track_visibility', 'onchange')
        initial_value = initial[col_name]
        new_value = getattr(self, col_name)

        if new_value != initial_value and (new_value or initial_value):  # because browse null != False
            track_sequence = getattr(self._fields[col_name], 'track_sequence', 100)
            tracking = self.env['mail.tracking.value'].create_tracking_values(initial_value, new_value, col_name,
                                                                                col_info, track_sequence)
            if tracking:
                tracking_value_ids.append([0, 0, tracking])

            if col_name in tracked_fields:
                changes.add(col_name)
        # 'always' tracked fields in separate variable; added if other changes
        elif new_value == initial_value and track_visibility == 'always' and col_name in tracked_fields:
            track_sequence = getattr(self._fields[col_name], 'track_sequence', 100)
            tracking = self.env['mail.tracking.value'].create_tracking_values(initial_value, new_value, col_name,
                                                                                col_info, track_sequence)
            if tracking:
                display_values_ids.append([0, 0, tracking])
                displays.add(col_name)

    if changes and displays:
        tracking_value_ids = display_values_ids + tracking_value_ids

    return changes, tracking_value_ids

• 不过

  • 我发现, 这个always和我想的用法不太一样, 他是只有在修改track_visibility为onchange的字段的值时才会记录, 也就是说, 当你修改没有设定track_visibility 的字段时, 不会记录always对应字段的值

• 啰啰嗦嗦

  • 看源码发现问题后
  • 就google了下odoo addon mail mail_thread.py "always"
  • 找到了不知啥版本的odoo
    • https://gitlab.merchise.org/merchise/odoo/blob/01b1830219ba617079561fce6b958e271a0df355/addons/mail/models/mail_thread.py
  • 看了看,美滋滋, 对always做了判断
  • 直接替换, 哪报错改哪, 完美
