Failed to upload picture with mongoid and carrierwave

[regdog]

I am happy to find this great gem. While I still don't figure out how to upload picture with carrierwave and mongoid. For example, I have a Blog model and field body which user can upload multiple pictures. What is the correct way to upload pictures to a blog entry?

Should I make the blog model and RedactorRails::Picure model as related models?

Class Blog ... has_many :pictures, :class => 'RedactorRails::Picure' accepts_nested_attributes_for :pictures end

Class RedactorRails::Picture < RedactorRails::Asset ... belongs_to :blog end

Then how to handle in the new/edit form and the controller?

Could you have a tutorial wiki to explain it? Thanks!

I figure it out now. The gem creates RedactorRails::Picture model to save the uploaded pictures and the blog entry just need to embed the picture paths in the body text.

But I met a issue when uploading picture as following. I found the same issue reported around the internet http://pastie.org/pastes/4270763 and http://stackoverflow.com/questions/17683481/minimagickerror-failed

I am using rails 3.2.13, devise, carrierwave and carrierwave-mongoid following the installation instruction, no customized devise user model.

I find the reason. Just installing the ImageMagick package on my system will solve the issue.
