Mislav-will_paginate(will_paginate)

Rails

mislav-will_paginate(will_paginate) doesn’t work after search.

servers_controller.rb
def index
@servers = Server.paginate(:page => params[:page], :per_page => 20,
:order => ‘device_id ASC’)
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @servers }
end
end

def search
@servers = Server.paginate(:page => params[:page], :per_page =>
20, :order => ‘device_id ASC’, :conditions => [“hostname like ?”,
“%”+params[:keyword]+"%"])
render :action => ‘index’
end

index.html.erb
<%= will_paginate @servers %>

paginate works fine for index, but after search, only first page is
showed,
when I click “next” or “2”, the error appears.
ActiveRecord::RecordNotFound (Couldn’t find Server with ID=search):
app/controllers/servers_controller.rb:26:in `show’

It seems like paginate doesn’t know, params[:keyword],
I haven’t done anything for “def show” in servers_controller.rb.

def show
@server = Server.find(params[:id])

respond_to do |format|
  format.html # show.html.erb
  format.xml  { render :xml => @server }
end

end

How can I resolve this issue?

Check your routing and URLs. I suspect they don’t match for search.

I added it to routes.rb
map.search ‘/search’, :controller => ‘servers’, :action => ‘search’
But I receive different error at this time,
TypeError in ServersController#search
can’t convert nil into String

It seems like paginate doesn’t no what keyword has been used for search
on next page,
so I changed view from <%= will_paginate @servers %> to
<%= will_paginate @servers, :params => {:keyword =>params[:keyword]} %>

“:params => {:keyword =>params[:keyword]}” this part is hand the
parameter to the next page.

What I have done is created search.html.erb instead of using
index.html.erb,
the only difference between search and index is
“:params => {:keyword =>params[:keyword]}”

and added routes.rb, and modified “def search” in servers_controller.rb
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @servers }
end

instead of
render :action => ‘index’

It works fine now.
Thank you Jeffrey.
