Two will_paginate objects in single page:

in controller:

@users = User.all.paginate(:page => params[:page], :per_page => 5)

@clients = Client.all.paginate(:page => params[:page], :per_page => 5)

in view:

<%= will_paginate @users %>

<%= will_paginate @clients %>

it will take params[:page] as param so when click on any of pages of client or use..both will navigate to another page.

Insted of that,

@users = User.all.paginate(:page => params[:user_page], :per_page => 5)

@clients = Client.all.paginate(:page => params[:client_page], :per_page => 5)

in view:

<%= will_paginate @users , :param_name => 'user_page'%>

<%= will_paginate @clients, :param_name => 'client_page' %>

Now it will work perfectly...
