Access group vars from callback module in ansible-2.0

[tiny...@gmail.com]

Hello,

I'm trying to write callback plugin for ansible.

Below code was working on in ansible-1.9, but it isn't in ansible-2.0

def v2_playbook_on_play_start(self, play):

    self.play = play

    self.playbook = self.play.playbook

    self.inventory = self.playbook.inventory

    self.playbook_name, _ = os.path.splitext(os.path.basename(self.playbook.filename))

    for g in self.inventory.get_groups():

        vars = self.inventory.get_group_vars(g)

        print("... vars for group %s" % g.name)

        for v in vars:

             print("%s = %s" % (v, vars.get(v)))

....

Error:

 [WARNING]: Error when using <bound method CallbackModule.v2_playbook_on_play_start of <......CallbackModule object at 0x7fbf9c8c8c50>>: 'Play' object

has no attribute 'playbook'

How should i access group/host variables from callback module in ansible-2.0?

Thanks in advance.

Did you ever figure this out? I'm running into the same issue.

I'm using below hacky approach (found somewere on the internet ;)

    def __init__(self):

        self.myvar = None

        ....

    def v2_playbook_on_play_start(self, play):

        var_mgr = play.get_variable_manager()

        p_vars = var_mgr.get_vars(loader=play.get_loader())

        self.inventory_name = p_vars.get('inventory_file')

        # initialize

        inv = var_mgr._inventory

        # group vars

        self._display.vvvv('... group vars')

        for g in inv.get_groups():

            self._display.vvvv('... group=' + str(g))

            self._display.vvvv('... value=' + str(inv.get_group_variables(g)))

            g_vars = inv.get_group_variables(g)

            # get vars if not defined already (hopping groups are sorted)

            if self.myvar    is None: self.myvar    = g_vars.get("myvar", None)

        # host vars

        self._display.vvvv('... host vars')

        for h in inv.get_hosts():

            self._display.vvvv('... host =' + str(h))

            self._display.vvvv('... value=' + str(inv.get_host_vars(h)))

            h_vars = inv.get_host_vars(h)

            if self.myvar    is None: self.myvar    = h_vars.get("myvar", None)

        # extra_vars: highest priority

        e_vars = var_mgr.extra_vars

        self.myvar    = e_vars.get("myvar", None)

        ....

This should work with 2.0 - 2.1 (hope ansible will not change it soon, or provide 'official' way).
