Hello all…  
I’m new in Ruby on Rails. I’m doing an application which needs to use  
pagination. This is ok. I got to use it and I didn’t find any error. But  
I’ve got to put a city names “research” too. That’s the problem. The  
pagination failed. the variable doesn’t take its value. Below it’s my  
city’s list:

Aracaju Editar Excluir  
Borborema Editar Excluir  
Brasília Editar Excluir  
Campinas Editar Excluir  
Campo Largo Editar Excluir  
Curitiba Editar Excluir  
Curralinho Editar Excluir  
Diadema Editar Excluir  
Florianópolis Editar Excluir  
Fortaleza Editar Excluir

I want to look for all cities with letter “a”. My code find them. But  
when I try to go to 2nd page, there is an error:

You have a nil object when you didn’t expect it!  
You might have expected an instance of ActiveRecord::Base.  
The error occurred while evaluating nil.[]

My variable doesn’t take the “research”. Does anybody know what I can do  
about that? Thanks a lot…

I’m not sure what you mean, but if you need to include the “research”  
variable in your form (eg. for page 2) you can use a hidden field for  
that purpose…

Ok, thanks a lot… I’ll try that. Just to know, my problem is like  
described below:

* * *

How would I redirect a will\_paginate link to a different, nested  
resource?

For example, on the entries page I am paginating entries and it works  
just fine. On the home page, I am also paginating entries, but only the  
first 10 results. If you click next, I would like the user to be sent  
to page 2 of the entries page.

The following does not work, as I am trying to go to  
/journals/:id/entries?page=2

Code : - fold - unfold

1. :params =\> { :controller =\> “journal”, :action =\> “index” }

It instead leads to /entries/index/3?page=2. Basically, I am trying to  
send it:

Code : - fold - unfold

1. :url =\> journal\_entries\_path(@journal)
