Dear Madam/ Sir,

This is my first post, and I am stuck it for many months.

I have below error msg:

NoMethodError (undefined method `paginate' for #<Class:0x640ccc4>): app/controllers/manage_controller.rb:24:in`list’

Here is my code:

def list

```
#@images = Image.paginate :page => params[:page], :per_page => 5
@items = Item.paginate :page => params[:page], :per_page => 5
#@items = Item.paginate(:page => params[:page], :per_page => 10)
#@user_pages, @users = paginate ( :users, :per_page => 5 )
#@babysitters = Babysitter.cached(:list).paginate(:page =>

```

params[:page],:per\_page =\> 10)  
# :per\_page =\> 10, :order =\> ‘created\_at  
DESC’  
#@users = User.paginate(:page =\> params[:page])  
#@items = Item.paginate(:page =\> params[:page])  
#@items = Item.paginate(:page =\> params[:page], :per\_page =\> 5)  
#@careers = Career.paginate :page =\> params[:page], :per\_page =\>  
10

end

I did add require ‘will\_paginate’ after the end of environment.rb,  
what else I can do now?

Thanks and Best Regards,  
Jeff

Don’t do that - use config.gem to load gems (in 2,x that is - look at  
bundler if you are using rails 3)

I write the config.gem ‘will\_paginate’ in the inside of  
environment.rb, but got below error msg:

undefined local variable or method ‘config’ for main Object

How to fix it? Thanks.

You’re probably putting it in the wrong place. What does your  
environment.rb look like

Yes, I put it before the end, then the is passed.

But the undefined method `paginate’ for #Class:0x6782980 is happened  
again.
