If the issue is in the create action please provide the corresponding  
code. Model code would be helpful too.

Compare this line to the equivalent line in the new action. What is the  
@  
doing inside the []? I don’t know whether it should be borrower\_id or  
not,  
that depends on what params are being passed. Look in the log to see  
what  
the params are when you click on create.

I have two modelds

1. loan model belongs\_to :borrower
2. borrower model has\_many:loans  
In my borrower Show method i wrote  
\<%= link\_to ‘Request New Loan’, :controller =\> ‘loans’, :action =\>  
‘new’, :id =\> @borrower.id %\>

my loans\_controller have this  
def new  
@borrower = Borrower.find(params[:id])  
@loan = Loan.new

respond\_to do |format|  
format.html # new.html.erb  
format.xml { render :xml =\> @loan }  
end  
end

def create

@loan = Loan.new(params[:loan])  
@borrower = Borrower.find(params[@borrower\_id])  
respond\_to do |format|  
if @loan.save  
format.html { redirect\_to(@loan, :notice =\> ‘Loan was  
successfully created.’) }  
format.xml { render :xml =\> @loan, :status =\> :created,  
:location =\> @loan }  
else  
format.html { render :action =\> “new” }  
format.xml { render :xml =\> @loan.errors, :status =\>  
:unprocessable\_entity }  
end  
end  
end

new method’si am getting borrower id prints very well .
