rspec users - Jul 2007 - Accessing content_for html in view specs?

Hi All,

Hope all is going well.

I''ve got a few views that create some content using
''content_for'' blocks

<% content_for :blah do %>
	.....
<% end %>

Has anyone worked out a way to be able to access the html that''s  
generated inside those blocks?

Since they''re not part of the view, have_tag('''')
seems to miss them,
and at the moment I can''t find a way to be able to access the  
generated content?

Any thoughts, ideas appreciated.

Cheers,

Marcus

Since have_tag wraps assert_select, you may want to post this to the
rails mailing lists as well.

It ends up in @content_for_blah, doesn''t it?

I thought it did too, but that''s a nil reference in the spec  
unfortunately.

Well, it''s an instance variable in the view, not your spec. This was  
discussed recently on rspec-users (starts at http://rubyforge.org/ 
pipermail/rspec-users/2007-June/002222.html and continues into July)  
with the general consensus being that you can write a helper or use  
instance_eval if you *really* want to access your view''s instance  
variables, but that you''re almost always better off specifying this  
sort of behaviour by expecting the output to show up in the place  
where it''s meant to show up, e.g. have_tag() on the view that does  
yield :blah in your case, rather than fiddling about with state.
