Passing the article object to the
`form_with`
method will automatically set the URL for
submitting the edited article form. This option tells Rails that we want this
form to be submitted via the
`PATCH`
HTTP method, which is the HTTP method you're
expected to use to
**update**
resources according to the REST protocol.
The arguments to
`form_with`
could be model objects, say,
`model: @article`
which would
cause the helper to fill in the form with the fields of the object. Passing in a
symbol scope (
`scope: :article`
) just creates the fields but without anything filled into them.
Also, passing a model object to
`form_with`
, like
`model: @article`
in the edit
view above, will cause form helpers to fill in form fields with the corresponding
values of the object. Passing in a symbol scope such as
`scope: :article`
, as
was done in the new view, only creates empty form fields.
More details can be found in [form_with documentation]
(http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-form_with).
