I wanted to add uploaded files to the survey response model defined by the Surveyor gem. I’d gotten most of the changes right, and the filenames were showing up in the model, but Paperclip wasn’t saving the files to the filesystem. As it turns out, Paperclip requires that your attributes (ex: :file_value> for my file column) be tagged with
attr_accessible, not just
Once you define one
attr_accessible item, you need to define all the ones you need, or mass-assigning attributes with
update_attributes will fail. This meant adding a whole bunch of attributes to my
attr_accessor list, too.
If you’re using
accepts_nested_attributes_for, you will also need to use
attr_accessible there, too.
Sharing the note here just in case anyone else runs into it. Props to Tam on StackOverflow for the tip!
