Question

I have a Controller with the function getAccounts where I look for certain accounts. My idea is to first show the number of results and then send the result array to the next function called showAccounts which generates the view. First of all I declared the result array as an instance variable. Then I tried to send with a form tag. It does not work … Has anyone an idea?

  def getAccounts
filter = '(uid='+params[:id]+')'
attrs = ['*']
@accounts=Array.new

conn = LDAP::Conn.new($HOST, $PORT)
conn.bind('cn=admin, dc=cippool-mb, dc=rwth-aachen, dc=de','DLPins!')
conn.perror("bind")

begin
  conn.search($base, $scope, filter, attrs) { |entry|
    setAttributes(entry)
  }
 rescue LDAP::ResultError
   conn.perror("search")
   exit

 end
 conn.perror("search")
 conn.unbind


end

def showAccounts

end

The view where I send the data.

Es wurden <%= @accounts.size %> Accounts gefunden.  

<%= form_tag :action => "showAccounts" do %>
  <%= hidden_field_tag "accounts", @accounts %>
<%= submit_tag "Anzeigen" %>

<% end %>

I can also paste the view where I need this array, but I dont’t think it’s relevant for this question. I use Rails 3.2.7 and Ruby 1.9.2p0

If you want to pass some large amount of data between separate requests I would suggest using session, it’s designed for such things.
