Rails中的will_paginate错误

Question

Excuse me I have a problem with will_paginate plugin.

In localhost, in my controller, I use person.operations.descend_by_date.paginate :page => params[:page] || 1 person.operations.descend_by_date.paginate :page => params[:page] || 1 . However in production the method show error. I think that the problem is thye parameter page. Because person.operation.descend_by_date return a collection i try passing only params[:page] || 1 passing only params[:page] || 1 .

However in localhost show error. The rare subject is:

If I evaluate the method once => Show error IF i evaluate the method twice or more times => works ok

Rails show this message error: hash parameters expected

Why could be the error?

Answer 1

First i convert the will_paginate object to array and then i use the method for arrays of will_paginate

person.operations.descend_by_date.to_a.paginate params[:page] || 1

Thanks
