Issues Attaching Files to Statuses

I've been following the Advanced Social Features in Ruby on Rails series and I'm currently stuck on the Displaying Files video. Every time I try to post a new status with a file attachment, I get this error:

Paperclip::Error in StatusesController#create Document model missing required attr_accessor for 'attachment_file_name'

I've already searched the Treehouse Forums thoroughly for all related posts. After implementing the suggested solutions, I end up with this error instead:

undefined method `attachment_content_type' for #<Document:0x007fdb9b049858>

app/controllers/statuses_controller.rb:43:in `create'

Now I'm stuck and I'm not sure what went wrong. Any help would be greatly appreciated, thanks!

Here's my document model:

class Document < ActiveRecord::Base
    attr_accessible :attachment
    has_attached_file :attachment

    attr_accessor :attachment_file_name

    validates_attachment_content_type :attachment, :content_type => %w(image/jpeg image/jpg image/png image/gif)
end

What's in your statuses_controller, this error here:

app/controllers/statuses_controller.rb:43:in `create'

In fact, please paste your entire create method under statuses_controller.

def create
    @status = current_user.statuses.new(params[:status])
    respond_to do |format|
      if @status.save
        format.html { redirect_to @status, notice: 'Status was successfully created.' }
        format.json { render json: @status, status: :created, location: @status }
      else
        format.html { render action: "new" }
        format.json { render json: @status.errors, status: :unprocessable_entity }
      end
    end
  end

I changed my document model to this, and I no longer get an error. However, the file still doesn't attach to the status...

class Document < ActiveRecord::Base
    attr_accessible :attachment
    has_attached_file :attachment
    do_not_validate_attachment_file_type :attachment
    attr_accessor :attachment_file_name
end

Thanks!

See above.

Karina Mio What does your log say when you attach an attachment? Can you possibly post a link to your code so we can take a look?

Nevermind, I got it.
