Editing a status update
Similar to the add feature, the edit feature will use a route in the
App
as well as a function in
graphstory.js
,
which are
edit
and
edit_content
, respectively. The edit content route passes in the content object, with its content
id, and then calls the
edit_content
method in Content class, which is shown in Listing 10-33.
