ActionController known Format - ruby-on-rails

Question

I am having an issue with this code. It is for uploading an audio file. When I upload it I get an error saying this:
ActionController::UnknownFormat at /users/1/audios/dfdfdsdsf ============================================================ > ActionController::UnknownFormat app/controllers/audios_controller.rb, line 67 --------------------------------------------- ``` ruby 62 if #audio.errors.empty? && #audio.update_attributes(update_audio_params) 63 respond_to do |format| 64 format.html { redirect_to user_audios_path(#user) } 65 end 66 else > 67 respond_to do |format| 68 format.html { render :edit } 69 format.js { render json: { result: :failed, errors: #audio.errors } } 70 end 71 end 72 end ``` App backtrace ------------- -

It might have to do with the respond_to block. Here is the code of that bellow:
def update
if params[:audio][:attachment].blank? && update_image_params.present?
#audio.update_audio_cover_picture update_image_params["photo"]
end
if #audio.errors.empty? && #audio.update_attributes(update_audio_params)
respond_to do |format|
format.html { redirect_to user_audios_path(#user) }
end
else
respond_to do |format|
format.html { render :edit }
format.js { render json: { result: :failed, errors: #audio.errors } }
end
end
end
This is a copy of the same code I use for my other project. It completely works on that app:
def update
if params[:book][:attachment].blank? && update_image_params.present?
#book.update_book_cover_picture update_image_params["photo"]
end
if #book.errors.empty? && #book.update_attributes(update_book_params)
respond_to do |format|
format.html { redirect_to user_books_path(#user) }
format.json { render json: { result: :success, url: user_books_url(#user) } }
end
else
respond_to do |format|
format.html { render :edit }
format.js { render json: { result: :failed, errors: #book.errors } }
end
end
end

From what your stack tells, it has something to do with the update method on your #audio. You are probably passing in weird parameters, or somehow filtering it incorrectly in your update_audio_params method.
