I would like to have an array saving fields to display for an object  
that is used for it’s form on multiple pages.

I have declared the array in each of the controller methods that would  
use it. for example,

def new  
@echantillon = Echantillon.new

@new\_ech\_columns = Array.new

@new\_ech\_columns = [  
[“Brut”,“brut”],  
[“Disponibilite”,“availability”],  
[“numero d’inventaire de l’oeuvre”,“inv”],  
[“denomination”,“name”],  
[“numero du laboratoire”,“oeuvre\_work\_number”],  
[“type d’echantillon”,"echantillont

```
etc....

```

and also in

def edit

@new\_ech\_columns = Array.new

@new\_ech\_columns = [  
[“Brut”,“brut”],  
[“Disponibilite”,“availability”],  
[“numero d’inventaire de l’oeuvre”,“inv”],  
[“denomination”,“name”],  
[“numero du laboratoire”,“oeuvre\_work\_number”],  
[“type d’echantillon”,"echantillon

etc…

and in other methods. Where can I put the array so that I only have  
to define it once and then use it repeatedly on different pages?
