attr_accessor and uploaded files

rubyonrails-talk

Hello everyone,

I was having an issue accessing the uploaded file in my model when I passed it with the params hash like:

  def create     @user = User.new(params[:user])     if @user.save       redirect_to( @user )     else       @title = "Sign up"       render 'new'     end   end

I thought it would work because it worked for :password and :password confirmation in my model with:

  attr_accessor :password, :password_confirmation

Which as I understand gives you setters and getters for the symbols that are passed. So I added:

  attr_accessor :password, :password_confirmation, :uploaded_file

And I got errors saying uploaded_file was a nil class

I got it to work by simply creating a function in my model:

  def pass_upload( upload )     @profile_picture = upload   end

And then in my controller:

  def create     @user = User.new(params[:user])     @user.pass_upload(params[:user][:profile_picture])     if @user.save       redirect_to( @user )     else       @title = "Sign up"       render 'new'     end   end

But this does not seem like the best methods I was wondering if any one knew why attr_accessor wouldn't allow easy access to the upload_file class like it did with the more simple variables :password and :password_confirmation.

Thank you

What gem/library are you using to handle uploaded files?

File uploading isn’t built in to rails, so you’ll need to use something like the paperclip gem, if you aren’t already.
