Receiving "You are already signed in" flash[:error]

[sethtrain]

After setting up devise and devise_masquerade all standard install from the documentation I get the flash[:error] result of "You are already signed in". I am running version 4.7.1 of devise and 1.2.0 of devise_masquerade.

If you look at the development log you will see Filter chain halted as :require_no_authentication rendered or redirected

Below is the log file in hopes that it helps with the issue:

On redirect to HomeController there are some things that happen because I am able to successfully see a button that will reverse the masquerade so user_masquerade? seems to be working successfully. The back_masquerade_path also works as you would expect.

On the views the current_user isn't the user I expect it to be as it is the user logged in before masquerading.

Hi @sethtrain .

Could you give a try and set Devise.masquerade_bypass_warden_callback=true?

Thank you!

[sethtrain]

Hi @oivoodoo

Unfortunately, this setting doesn't seem to fix the issue.

[sethtrain]

After doing some debugging on this in RubyMine I am seeing find_by_masquerade_key(params[Devise.masquerade_param]) in find_resource to be the problem. I don't know just yet why but that is the piece that seems to be returning and empty recordset.

[oivoodoo]

@sethtrain could you verify you expires_in settings? Now token has only 1.minute by default to click Login As from UI

[sethtrain]

@oivoodoo Yes, it is 1.minute

[oivoodoo]

@sethtrain need to run away for one hour. come back to give a try to review the code again. I would suggest for now to add pry inside of masquerade! and show action if you have time to debug otherwise I will review it. thank you!

[sethtrain]

@oivoodoo Sure thing, I'm deep in the debugger at the moment so I will let you know what I find. Thank you for your help.

[sethtrain]

@oivoodoo I figured it out. I was running in development mode with config.action_controller.perform_caching = false and config.cache_store = :null_store. So the fix was to touch tmp/caching-dev.txt which would then allow for memory caching to work and all of the masquerade token stuff to store correctly.

[oivoodoo]

@sethtrain oh. it sounds great! thank you that you resolved the issue.

[sethtrain]

@oivoodoo Thanks for sticking with me while I debugged it. I will now close the issue.

[garymh]

I'm actually getting this too... Is there a way to fix it without enabling caching?

[sethtrain]

@garymh I didn't find a way to do it without enabling caching.

[leastbad]

@oivoodoo I love this library, and it's 99% of the way to "it just works" status.

Can you please add instruction in your README.md for devs to make sure development mode is being cached? I lost so much time debugging this issue and while I'm thrilled it was such an easy solve, the actual solution is anything but obvious and if people don't find this thread, it's basically impossible to achieve successful integration in development.

Developers can run rails dev:cache one time during project bootstrapping and never have to worry about this behaviour.

Hey @pjforde1978 . I am a bit busy the last days, if you have some time I would really appreaciate to have the pull request to update README.md. Thank you!
