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

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

On loan create Giving error can not find borrower without an id but on new method’si am getting borrower id prints very well .

def create

@loan = Loan.new(params[:loan])

@borrower = Borrower.find(params[@borrower_id])

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.
