" undefined method `[]' for nil:NilClass "

<% 
 @loans.each do |loan_rec| 
  loan=loan_rec.info 
  if loan['_LoanName'].blank?
    loan_name = 'No Loan Title'
  else
    loan_name = loan['_LoanName']
  end
end
%>

I am getting error of undefined method `[]' for nil:NilClass. What is undefined? and when I print loan array in a loop, it gives the following result:

{
  "_LendingCategory"=>"Private Real Estate Loan",
  "Email"=>"[email protected]",
  "FirstName"=>"TestDavid",
  "Id"=>3573,
  "_LoanName"=>"null",
  "LastName"=>"TestGeorge",
  "_DesiredTermLength"=>"3",
  "_TransactionType0"=>"Purchase",
  "_CashContribution"=>100000.0,
  "_NetLoanAmountRequested0"=>8000000.0
}

You need to anticipate that there might not be an info for every loan_rec. I would refactor your code like this:

<% 
  @loans.each do |loan_rec| 
    loan = loan_rec.info 
    loan_name = loan && loan['_LoanName']
    if loan_name.blank?
      loan_name = 'No Loan Title'
    end
  end
%>

In your loan, there is no any info key. So you would have at aleast one info value.

You have at least one Loan for which loan_rec.info is nil. You can try:

loan = loan_rec.info || Loan.new

as a quick fix, but you should also figure figure out how to avoid the nil in the first place.
