Hi all,

i have a form and the form is validating correctly. the relevant table  
to this model has a coloum to store a some text(a auto generated text.).  
to store text to this coloum i am not giving it from a normal form.  
instead of that i want to pass a values to this model from a another  
different model so it can save in the table.

pls any one know how to archive this task.

Thank  
Nadeesha

So if I understand you correctly, it sounds like you have two models:  
A and B. Model A has an attribute that allows text to be stored in it,  
and this attribute is populated by model B. So, what you want to do  
is:

class B \< ActiveRecord::Base

# id: the id of the record where the text should be stored

# text: the text to be stored

def populate\_text\_field(id, text)  
if a = A.find(id)  
a.update\_attribute(:text\_field, text)  
end  
end

end

Is this what you are intending?
