Update attributes from slightly different params

In the update action of my controller, I have this kind of code :

@loan.update_attributes(loan_params)
@loan.update_attributes(confirm: nil)

I want to make the same with only one request to the database. Do you know how to do it ?

I think this can help you Probably loan_params will be a hash generated as loan => {:key => :val}

SO the confirm attribute will be merge to the the loan hash for updating the @loan 

loan_params['loan'].merge!(confirm : nil)
@loan.update_attributes(loan_params)

Try this one :

loan_params.merge!(:confirm => nil)
@loan.update_attributes(loan_params)

or 

loan_params.merge!(confirm: nil)
@loan.update_attributes(loan_params)

Thanks
