Missing template blogs/index on Ruby on Rails project

Question

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

ActionView::MissingTemplate: Missing template blogs/index with {:handlers=>[:rx

Answer 1

I did this: In my controller, I put a before filter:

def acceptable_mime_type
  unless request.accepts.detect{|a| a == :json || a == :html} || request.accepts.include?(nil)
    if request.accepts.detect{|a| a.to_s().include?("*/*")}
      ActionDispatch::Request.ignore_accept_header = true
    else
      render text: "Unacceptable", status: 406
      false
    end
  end
end

It checks for my supported types (e.g. json, html) and nil (nil renders default html), then if those mime types aren't supported, it checks for "/" in the header. If it finds it, I force rails to render the default mime type by ignoring the accept header.

To test this in rspec, I had to do this:

describe 'bad header' do
  describe 'accept' do
    let(:mimeTypes) { ["application/text, application/octet-stream"] }

    it 'should return a 406 status code' do
      request.accept = mimeTypes
      get 'index'
      expect(response.response_code).to eq 406
    end

    describe 'with */* included' do
      it 'should return a 200 status code' do
        request.accept = ["*/*"] + mimeTypes
        get 'index'
        expect(response.response_code).to eq 200
      end
    end
  end
end

For some reason, I was getting problems trying to send accept headers properly in rspec using the methods described here, but I found if I set request.accept to an Array, both my tests passed. Weird, I know, but I'm moving on to the next issue for now.
