NoMethodError - I'm stuck, please help

[Levi Rosol]

I've spent a ton of time on this bug, and am looking for any help I can get. Last week I started seeing an issue where my site started throwing NoMethod errors on a particular controller. The odd thing is that I only see this error in production. In development everything works exactly as expected.

Looking at my logs I can see specifically when the error started showing, but there were no code changes prior to that date.

The error is when I view any of my group pages. index, edit, and show all error on the first method they try to call. They each point to a different method that I have confirmed is in my groups.rb file.

The site is hosted on webbynode.

Because everything works fine in dev, I was leaning toward it being a db issue. So, i created a new db, pointed my prod site to it, ran the migrations, but still saw the exact same error.

Does anyone have some suggestions as to what I should look at? could it be a config setting?

I can post some of the logs tonight, but i really don't think they will help.

pretty sure that's not the case, but it's worth a second look.

Looks like some kind of code reloading problem. Can you post a stack trace?

Thanks,

Bruno

[Levi Rosol]

I can (tonight when i get home), but depending on the view you go to, you get a different error. All of them being NoMethod errors, but each point to the first method that the view is trying to call.

It's almost as if it cannot find the model.

btw, I do fully expect this to result in "forehead smack" type issue. It has to be something silly.

so going off of the posts in the other somewhat related thread, i started looking into some code that was recently added by another dev. I found a situation where there was a new control, team.rb, that was overriding the group controller. This was what was causing me error.

It's important to note that the only way i could reproduce it in dev is to set
config.cache_classes = true
in the development.rb. With it set to false, everything ran just fine.

I seem to remember a thread from many months back where people (myself included) were having similar errors, but only in dev, related to the aws-s3 logic.

hope this helps someone down the road.

Referring to the "In Production, the Strange Error 'undefined method
`controller_name' for nil:NilClass' is Back" thread of the past day or
so, did you have a cache_sweeper directive in the overridden
controller?

I had a similar bug, with a similar hack-fix, namely setting
config.action_controller.perform_caching to false.

I had cache_sweeper directives in both the CE and overridden
controllers. Eliminating it from the overridden controller was the
fix.

[Levi Rosol]

nope, the only thing the overridden model had in it was:

  has_many :home_games,     :class_name => "Game", :foreign_key => :home_team_id
  has_many :visitors_games, :class_name => "Game", :foreign_key => :visiting_team_id

Is there any overridden controller logic?

[Audrey A Lee]

I too have bumped into this nil:NilClass (NoMethodError)

Everything works fine in development.

But script/server coughs up an error when I
export RAILS_ENV=production

I've overridden these controllers:

application_controller.rb
posts_controller.rb
users_controller.rb

More info which I got from my development environment since
script/about will not run on production:

[Audrey A Lee]

ok,

I was able to easily work-around this bug.

I can now run my site under RAILS_ENV=production

All I did was move my controllers out of RR/app/controllers/ down
inside of vendor/plugins/community_engine/app/controllers/

Now RR/app/controllers/ is empty.

This appeals to me.

I dont like have controllers in two places.

[Bruno Bornsztein]

Sorry, that's really not the best approach. This has been discussed in many threads before (and it's fixed in edge), but the right way to work around this is to use an initializer:

http://gist.github.com/216991

Moving all the CE controllers to your app directory is not the correct way to solve this problem.

Thanks,
Bruno

Bruno,

thanks for your help with this.

I appreciate your efforts.

I moved my controllers back to RR/app/controllers.

I replaced vendor/plugins/community_engine with edge.

I now see this:
