`@active_record/relation' is not allowed as an instance variable name

[Bob Sleys]

Came into work this morning and fired up the app I've been working on and received the error message

`@active_record/relation' is not allowed as an instance variable name

I believe I did a bundle update last time I was working on the project and might not have restarted the server.  I get this error upon hitting the first hobo_controler

To try to figure out what was going on I created a fresh rvm gemset, installed hobo --pre and created a new test project.  It fired up fine so I add a resource 'hobo g resource organization'.  Once I went to /organizations I got the error again.  I tried adding something besides time stamps to the model fields, ie name :string, ran a migration and still get the error.

Did something change in hobo --pre last week that could be causing this?  or is it some other gem?

Sorry ignore this...it has to do with the will_paginate pre4 problem already reported...should have looked that one over more closely.

Hi,

I also ran into this exact problem, however I've been unable to drop down to will_paginate 2.3.15 (which is installed) due to a dependency error when running bundle install:

Bundler could not find compatible versions for gem "will_paginate":

  In Gemfile:

    will_paginate (= 2.3.15)

    hobo (= 1.3.0.RC1) depends on

      will_paginate (3.0.pre4)

Did you get it to work?

Thanks in advance,

Ja

In my case I had 2 version of will_paginate installed so I just uninstalled the higher level one and updated my bundle.  Simply uninstalling the currently used gem doesn't update bundle so you need to have it update after you remove the bad version and had a hard coded version to your gemfile so bundler sticks to that version and doesn't try to install the higher version again.

i have install

rails 3.0.9
hobo 1.3.0.RC
---------

$Hobo new simo

$hobo g resource objetivo_global objetivo_global:string
$hobo g migrate

$rails s

then view next error:

NameError in ObjetivoGlobalsController#index

`@active_record/relation' is not allowed as an instance variable name

thanks

When you do the install of hobo it pulls in the latest version of will_paginate as a dependency.  The problem is the latest version is causing your problem. Add the following line to your gemfile.

gem "will_paginate", "3.0.pre2"

Then do a bundle install and check your installed versions of gems, gem list. You will probably see 2 version of will_paginate installed.  Do a gem uninstall will_paginate and select the one that isn't 3.0.pre2.  After that you should be good to go.

By adding the line above to the gemfile you are telling bundler to use that specific version. bundler install will install that version and set it in the gemfile.lock file. Once that is done it's safe to remove the version causing all your problems.

Good follow the instructions:

$ bundle install

Fetching source index for http://rubygems.org/

You have requested:

  will_paginate = 3.0.pre2

The bundle currently has will_paginate locked at 3.0.pre4.

Try running `bundle update will_paginate`

$ bundle update will_paginate

Fetching source index for http://rubygems.org/

.

Installing will_paginate (3.0.pre2) 

.

$ gem uninstall will_paginate

Select gem to uninstall:

 1. will_paginate-3.0.pre2

 2. will_paginate-3.0.pre4

 3. All versions

> 2

run mi app normally

 miapp$ rails s

Thas Ok! its Works

I tried several times but was still receiving errors. As a last resort I imploded rvm and started over.

works now :)

Thanks

Glad you got it working.
