teaforthecat / double_nested_fields.html.haml

Created February 13, 2013 16:35

This is an example of a field set using the nested_form gem along with the twitter bootstrap style framework. It enables very efficient editing of data and relationships since three objects can be edited at once. Instead of being directed to another form and having to go back, ajax is used to create a dynamic form.

	%li.reference_group
	.container-fluid
	.row-fluid
	.span1.move
	%i.icon-move
	.span4
	= f.input_field :label_markdown, placeholder: '<markdown enabled>'

teaforthecat / catalog_entry.rb

Last active December 13, 2015 17:08

Custom html parser. This was used to convert html files which were exported from an older Adobe InDesign file into markdown. The html was inconsistent and varied but this handled 90 percent of the files. The remaining cases were edited by hand in a form with a markdown enabled text area.

	# renders markdown with footnotes matching Pandoc's syntax,
	# but renders html with custom formatting in the class methods link_to_text_replace, link_to_fn_replace
	class CatalogEntry

teaforthecat / initializers_dragonfly.rb

Last active December 11, 2015 06:09

Store the processed image on the datastore before being served by dragonfly (pre-caching). The url needs to be accesses programatically, like in a background job.

	# store the job before it has a chance to be served by dragonfly
	images.configure do \|c\|
	c.define_url do \|app, job, opts\|
	thumb = ThumbTracker.where(job: job.serialize).first
	unless thumb
	uid = job.store
	thumb = ThumbTracker.create!(
	:uid => uid,
	:job => job.serialize
	)

	class TileProcessor
	def tile temp_object,tile_size=256
	geom = "#{tile_size}x#{tile_size}"
	temf = Tempfile.open('o.ptif')
	`convert #{temp_object.path} -define tiff:tile-geometry=#{geom} -compress jpeg 'ptif:#{temf.path}'`
	temf
	end
	end
	tiled_images.processor.register(TileProcessor)
