Refresh and invalidate cache question

[ju5t]

I can't seem to figure out how to refresh or invalidate the cache of a property in a model. We're caching API calls as follows:

class ABC(models.Model):
    @ecached_property('manufacturer:{self.id}', 86400)
    def manufacturer(self):
        return 'API'

Reading the documentation I assumed that to invalidate this entry I would do

item = ABC.object.get(id=1)
ABC.manufacturer.invalidate_cache_by_key(item)

This returns an error:

ValueError: Parameter "'self'" is required for "manufacturer:{self.id}"

Would you mind pointing me in the right direction?

Hi, thank you for reporting the issue, it looks like a bug.
Until I fix it, you can use the following approach:

from easy_cache import invalidate_cache_key, create_cache_key

invalidate_cache_key(create_cache_key('manufacturer', item.id))

Thanks for the update and workaround (and pretty awesome package!).

@ju5t Hi! Could you please install new version easy-cache==1.1.0 and let me know if the problem is fixed or not. Thank you!

[ju5t]

Unfortunately the error was still there. I've implemented the workaround for now which works perfectly.

Hi!
This error didn't reproduce with 1.1.0 version, the issue is done

@amokryshev Thank you for the validation!

[ju5t]

@amokryshev we need the workaround for it to work so I am curious what you're doing differently. Could you explain this?

@ju5t Hi! actually i've done nothing, Oleg proposed me to fix the bug, but it coudn't reproduced, all works fine.

I've publish my environment, take a look at the test_issue_8/tests.py https://github.com/amokryshev/easy-cache-issue-8
