I’m thinking that for some reason Rails isn’t seeing a content\_type so  
is falling back to .erb rather than using .html.erb, but I can’t  
figure out how this would happen or why it’s not able to find the  
correct file. I encountered this when changing this view from \<%=  
render @gigs %\>, which finds gigs/\_gig.html.erb just fine. I can post  
the contents of \_gig\_big.html.erb if necessary, but for the most part  
it’s just a copy of \_gig.html.erb (for now).

View:

 \<%= render :partial =\> 'gig\_big', :collection =\> @gigs %\>

Error:  
ActionView::TemplateError (Missing template gigs/\_gig\_big.erb in view  
path app/views) on line #9 of app/views/gigs/index.html.erb:  
6: \<% end %\>  
7:   
8:

  
9: \<%= render :partial =\> ‘gig\_big’, :collection =\> @gigs %\>  
10: 

  
11: \<% end %\>

Partial:  
…/app/views/gigs/\_gig\_big.html.erb exists

Of course it was the one thing I didn’t check and was not in the  
error: a leading space in the partial’s filename. A twitchy typo, and  
a proportional font didn’t help either.
