Detect if a trigger is being ignored for a model

[dablak]

Hi, in some situations, I need to check if a trigger is ignored.

For example:

with pgtrigger.ignore("app.Book:book_trigger"):
    is_trigger_ignored_for_model(book_trigger, book)  # True

with pgtrigger.ignore():
    is_trigger_ignored_for_model(book_trigger, book)  # True

is_trigger_ignored_for_model(book_trigger, book)  # False

I believe that I can check if a trigger is being ignored like this:

def is_trigger_ignored_for_model(trigger: pgtrigger.Trigger, model: models.Model) -> bool:
    ignored_uris = getattr(pgtrigger.runtime._ignore, "value", set())
    model_trigger_uri = trigger.get_pgid(model)
    return model_trigger_uri in ignored_uris

But pgtrigger.runtime._ignore is a private variable.

Would it be reasonable to add for example a method to the pgtrigger.Trigger class, like:

class Trigger:

    def is_ignored_for_model(self, model: models.Model) -> bool:
        ignored_uris = getattr(runtime._ignore, "value", set())
        model_trigger_uri = self.get_pgid(model)
        return model_trigger_uri in ignored_uris

I could create a PR if that sounds like a good idea.

Thanks!

@dablak I like this suggestion, although would prefer it being on the main interface too:

i.e.

if pgtrigger.is_ignored("trigger_uri")

Similar to pgtrigger.ignore(), I assume it'd raise an error on an invalid trigger URI

I believe this would be a pretty fast PR and would welcome it.
