[Rails] Re: Re: null values...

You have to show us the code in your view that has the form to make a
comment.

From your description, params[:body] is obviously not being set to
anything because you don't have a textarea or input box with the name
"body". If the name of the textarea or input is named "comment[body]"
then to access this value it would be params[:comment][:body].

Also if you have an association between users and comments, such as user
has_many :comments, you can just do

@blogcomment = @user.blogcomments.create(:id => params[:body])
