Question

Suppose I have a model Person which has a one to many relationship with itself (i.e. Parent -> Child). When show.html.erb is rendered on a given @person I would like it to also include the result of rendering of show.html.erb for the parent.

Essentially I would like the correct syntax for

<%= render @person.person %>

I actually tried manually doing

<%= render :file => "/persons/1.html.erb" %>

and it didn’t work. Can someone help me understand the syntax of render? Thanks.

(Note that I actually have a more complicated model and I am rendering SVG files, not html.)

Answer 1

Put most of the content of show.html.erb in a file called _person.html.erb and then in show.html.erb have this:

<%= render :partial => 'person', :locals => {:person => @person} %>

Use person instead of @person in _person.html.erb

(Note that the file name starts with an underscore.)
