Fragment cache can't modify frozen object error rails 3

[nazarhussain]

Hi, I faced some issues with fragment caching while using that gem. Please look at the link http://stackoverflow.com/questions/14347602/fragment-cache-cant-modify-frozen-object-error-rails-3/14377501#14377501 for more details.

Please address the issue, is it some bug in your gem or some other issue in AR.

I experienced the exact same issue and removing this gem fixed it for me.

[SamSaffron]

I think I just pulled a PR that fixes this, can you try grabbing latest from github to confirm its fixed?

[quainjn]

Still broken for me. Re-added the gem yesterday, and immediately started getting the same error:
"NoMethodError: undefined method `result' for #<RuntimeError: can't modify frozen object>"

[ryancheung]

Me too! The lasted branch still broke!

[etagwerker]

I'm also running into this issue. I'm trying with master and I'm getting this:

RuntimeError: can't modify frozen object: ROLLBACK

Any ideas? Thanks!

[variousred]

getting the same exact error as @etagwerker
rack-mini-profiler (0.1.31)

[z5h]

Same error rack-mini-profiler (0.1.31)

[rahult]

Same error rack-mini-profiler (0.9.0)

[EverybodyKurts]

I get this error as well. This happens to me in my custom Devise::OmniauthCallbacksController. Removing rack-mini-profiler immediately fixes this problem.

[jamilabreu]

+1 for this error on edge rails (4.1.0.rc1)

[d4rky-pl]

Yep, still a problem.

[manuelmeurer]

Seems like it's fixed in 0.9.1.
