will_paginate undefined method `total_pages'

Question

What am I missing here? I am using the haml_scaffold generator and the pages work fine with will_paginate. When I start tinkering I end up with this \'total_pages\' error an

Answer 1

@locations = Location.paginate(:all, :conditions => 'city = springfield')

@locations must be an object

in your example @locations is an Array

array cant have total_pages method

Answer 2

If anyone else is having this problem. In my case I did not call the pagination in my controller method last.

Example Before:

@foo = Foo.paginate(:page => params[:page], :per_page => 15)
@foo = Foo.do something

Example After: I called the pagination last within my method since rails reads from top to bottom and it seemed to fix my error.

@foo = Foo.do something
@foo = Foo.paginate(:page => params[:page], :per_page => 15)

Answer 3

include

require 'will_paginate/array' 

before loading that code will solve your problem.

Answer 4

I was encountering a similar a error undefined method 'total_pages' for ActiveRecord_AssociationRelation.

It turns out that renaming my variable solved the issue.

Here was my code:

@reviews = @user.reviews.paginate(page: params[:page], per_page: 5).order('created_at DESC')

I changed it to this:

@user_reviews = @user.reviews.paginate(page: params[:page], per_page: 5).order('created_at DESC')

And it solved the issue. It's very bizarre but it there may have been some kind of conflict.

Since I spent a few hours researching, I thought it might help someone one day as well!

Answer 5

try to change

@locations.paginate(:page => 1, :per_page => 2)

to

@locations = @locations.paginate(:page => 1, :per_page => 2)

hope this helps
