Dears I’m trying to get a form working in my application however I get  
the stack error for this in return.  
I allready found out that it’s situated in the def new declaration but  
have no clue how to solve this  
this is my controller

```auto
require "player"
class SpelersController < ApplicationController

  def index
    @speler = Speler.find(:all, :order => 'RAND()')
  end

  def all_sorted
  @heren=Speler.heren
  @dames=Speler.dames
  end

  def score_sn
  @senior=Speler.sr
  end

  def score_jr
    @junior=Speler.junior
  end

  def score_p
    @pupil =Speler.pupil
  end

 def score_top
   @man =Speler.topm
  @vrouw=Speler.topv
  end
def new
  @new = Speler.new
end
end
```

and this is my model

```auto
require
"C:/paul/ruby/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record"
class Speler < ActiveRecord::Base
 @@ploegen={ 'P' => 'pupil', 'J' => 'junior', 'SR' => 'senior'}

# def initialize(naam, achternaam, geslacht, score, ploeg='SR')
# @naam = naam
# @achternaam = achternaam
# @geslacht = geslacht if geslacht == 'V' || geslacht == 'M'
# if @@ploegen.has_key?(ploeg)
# @ploeg = ploeg
# else
# @ploeg = 'SR'
# end
# @score = score
# end
  ActiveRecord::Base.establish_connection(
  :adapter => "mysql",
  :host => "localhost",
  :username => "root",
  :password => "",
  :database => "vspw"
  )
class CreateSpelers < ActiveRecord::Migration
    def self.up
      create_table :spelers do |t|
        t.column :naam,:string
        t.column :achternaam,:string
        t.column :score,:integer
        t.column :ploeg,:string
        t.column :geslacht,:string

      end
      # TODO: Hiervoor heb ik een speler.make (of iets dergelijks)
aangemaakt. Deze zorgt ervoor dat
      # oa de ploeg correct wordt opgevuld
      Speler.create :naam => "jan",:achternaam => "Janssens",:score

    end
    def self.down
      drop_table :Spelers
    end
    #CreateSpelers.down
    #CreateSpelers.up
  end
  def self.iedereen()
  Speler.find(:all )
end

  def to_s
sprintf(" #{naam} #{achternaam} - #{score} ")
end
def self.heren
  Speler.find(:all, :conditions =>{:geslacht =>"M"})
end
def self.dames
  Speler.find(:all, :conditions =>{:geslacht =>"V"})
end
def ploeg
  @@ploegen = :ploeg
end
def self.sr
 @senior = Speler.find_by_sql("select naam,achternaam, score,ploeg from
spelers WHERE ploeg = 'SR' OR ploeg =''")
end
 def self.pupil
  Speler.find(:all, :conditions =>{:ploeg =>"P"})
end
def self.junior
  Speler.find(:all, :conditions =>{:ploeg =>"J"})
end
def self.topm
  @man = Speler.find_by_sql("select naam,achternaam, score ,ploeg from
spelers where geslacht ='M' ORDER BY score DESC").first(3)
end
def self.topv
  @vrouw = Speler.find_by_sql("select naam,achternaam, score ,ploeg from
spelers where geslacht ='V' ORDER BY score DESC").first(3)
end
#select naam,ploeg from Spelers where ploeg ="SR" OR ploeg = "";
#puts "Alle senioren :"
def speler
  @speler= :speler
end

end
```

my form looks like this

# Een nieuw lid toevoegen
\<%= error\_messages\_for 'Speler' %\>
# Nieuwe speler

\<%= error\_messages\_for :speler %\>

\<% form\_for(@new) do |f| %\>

name:  
\<%= f.text\_field :naam %\>

achternaam:  
\<%= f.text\_field :achternaam %\>

Score:  
\<%= f.text\_field :score %\>

score:  
\<%= f.text\_field :ploeg %\>

 \<%= f.submit "Create" %\> \<% end %\>

[/code]  
I know the create part is not mentioned in the controller but since I  
first would like to solve the stack error I left this out.  
this is the stack error

SystemStackError in SpelersController#new

stack level too deep
