6,734 PointsHow does :body link back to the text stored in the body?
I see that for the form.label if I change :body to :name or any other name it changes the name of the html text but for form.text_area if I change the name from body it wont load the text.
Do :body have two different meanings for form.label and form.text_area?
Can someone explain what the :title or :body represents?

Usually, when you have a form, each area is labeled as to what you need to enter...like name, email or password so that you know what info to put in which area. The form.text_area :body is referring to what info that particular table (Posts) is requiring in the database...so for the video example a Post contains a :title and a :body (which would be the text body of the post).

Treehouse TeacherTo expand on this: every Rails model has accessor methods for its attributes (the data it holds). So the Post
model has a title
method that's used to retrieve its title, and a body
method that's used to retrieve its body. The symbols that you pass to the form object's label
, text_area
, etc. methods should match the name of one of those attribute accessor methods.
So if you're presenting an edit form, form.text_field :title
will access the title
method of the Post
object, and pre-populate a form field with the title
method's return value. It will also cause the form to include a title
parameter in the submitted form data (which gets passed to the title=
method of the Post
model to set the updated title).

19,323 PointsHiya David! Can you post the whole code in order for me to understand what actually your :body or :name represents? OR atleast post your view file/partial containing these symbols? (:
