Question

For one of my projects I’m getting this exception every now and then:

ActionView::MissingTemplate: Missing template blogs/index with {:handlers=>[:rxml, :erb, :builder, :rjs, :haml, :rhtml], :formats=>[“image/jpeg”, “image/pjpeg”, “image/png”, “image/gif”], :locale=>[:en, :en]} in view paths “/var/www/keeponposting/releases/20110403083651/app/views”

It seems someone is requesting an image from a URL that isn’t an image:

HTTP_ACCEPT “image/jpeg, image/pjpeg, image/png, image/gif”

Any ideas what to do about it? Do I have to implement a handler for one of those and return “” to get rid of this exceptions or is there a better way to handle it?

Now I’m also getting this:

ActionView::MissingTemplate: Missing template blogs/index with {:formats=>[“text/*”], :handlers=>[:rjs, :haml, :rhtml, :erb, :rxml, :builder], :locale=>[:en, :en]} in view paths “/var/www/keeponposting/releases/20110415040109/app/views”

Isn’t there a way to send back HTML no matter what format is requested?

I fixed this issue (a few minutes ago – so far, so good) with this new Rails 3.1 option:

config.action_dispatch.ignore_accept_header = true

As mentioned in this Rails issue. That goes in config/application.rb.

I tested it like so in a RSpec request test (using Capybara):

it "should not break with HTTP_ACCEPT image/*;w=320;h=420 from iPhone" do
  page.driver.header "Accept", "image/*;w=320;h=420"
  visit "/some/path"
  page.should have_content("Some content")
end
