Hey I am making a photo website for a class and I am stuck i need to  
have a text\_area pick up a variable and put it in my controller to  
change the number of thumbnails that show up on my view page. I can not  
figure out how to create this and make a text\_area and button to submit  
it and have the page refresh with the new number of thumbnails on it.  
Here are some snippits of my code.

photos\_controller.rb

def list  
@photo\_pages, @photos = paginate :photos, :per\_page =\>  
((@params[:pagesize]) || 12)  
end

## def update\_list @pagesize = pagesize.new(params[:pagesize]) @pagesize.save @pagesize = pagesize.find(params[:pagesize]) #auto\_complete\_for :pagesize @photo\_pages, @photos = paginate :photos, :per\_page =\> pagesize.find(params[:pagesize]) end

list.rhtml

\<%= form\_tag({:action=\>'create'}, :multipart =\> true)%\>

Title  
\<%= text\_area 'pagesize', 'size' %\>

 \<%= submit\_tag "Submit" %\> \<%= end\_form\_tag %\>

\<% #render :action =\> ‘pagesize’ == @params[:pagesize] %\>
