Rails: Validating uniqueness without saving
# Had to do this for an importer tool that was being converted to a three-step validation-feedback-persist process
# Rails does not support uniqueness validation for a custom collection of unsaved ActiveRecord models
# Maybe someone finds this useful
def validate_uniqueness
ActiveRecord::Base.transaction do
@unsaved_entities.each do |entity|
entity.object.save # Executes validations/callbacks
entity.successful = entity.object.valid?
end
text_styles = %w(code del em ins sub sup strong)
text_styles.each do |m|
para = app.app.para(app.app.send(m, m, stroke: '#ccc'))
expect(para.text).to eq(m)

Fixing my local jekyll setup (pygments.rb-0.5.0/lib/pygments/popen.rb:358:in `rescue in get_header': Failed to get header. (MentosError))

Jekyll failing with:

Liquid Exception: Failed to get header. in _posts/filename.md/#excerpt
/home/philipp/.rvm/gems/ruby-2.0.0-p247@global/gems/pygments.rb-0.5.0/lib/pygments/popen.rb:358:in `rescue in get_header': Failed to get header. (MentosError)
        from /home/philipp/.rvm/gems/ruby-2.0.0-p247@global/gems/pygments.rb-0.5.0/lib/pygments/popen.rb:338:in `get_header

Tracked it down to mentos.py. Running mentos.py gave me the following error:

$ python mentos.py
