Combination with cocoon gem: Upload of base64 string works for creating a nested object, but not for updating it about carrierwave-base64 HOT 6 CLOSED

I have added model specs, and in the specs, the update works as expected.

jmuheim/test-carrierwave-base64-update@bd6a409

So it seems it's not a problem on the model's level.

I will try to add feature specs, showing the problem...

from carrierwave-base64.

I added feature specs which I hoped would show the problem, but somehow it seems to work in the specs, but not in the "live" browser, see here:

https://github.com/jmuheim/test-carrierwave-base64-update/blob/master/spec/features/users_spec.rb#L48

As @nathanvda, the creator of the cocoon gem, helpfully pointed out: it seems that when only setting the base64 string to a new string and no other attribute of the nested object, no update happens. But when in addition to the base64 string another attribute of the nested object is changed, then the update happens as expected, even for the base64 string:

nathanvda/cocoon#311 (comment)

So it seems to be some problem with ActiveRecord not being notified of an attribute change when only the base64 string was changed. You can reproduce this behaviour easily in the browser:

• Create a user with an attachment
• Edit the user:
  • When you only set the base64 string to a new one, it won't be saved as a new image
  • When you set the base64 string to a new one and also set a new name, the name and the base64 string are saved

I have no idea why in the specs it works but not in the "live" browser. Any help fixing this problem is highly appreciated. Thanks.

I'll be on holidays the next week. It would be very nice to see some progress here until then, as our application heavily depends on your gem in combination with nested attributes and cocoon.

If I can be of any help afterwards, please ask. Thank you.

I will take a look in a couple of days, had no time yet

It's great to hear that you're planning to take care of it. I'm very eager to know where exactly the problem lies. Be sure to take also a look at the corresponding ticket at cocoon's side:

nathanvda/cocoon#311

Best wishes.

The problem was that the attribute was not marked as updated by the carrierwave gem. Your test app works as expected with the new version of carrierwave-base64.

Sorry that it took a while for me to fix it, i was on vacation the last week.
