rails admin performance in development with vs. without using model configs/included_models

	app has 68 models of which 34 are included in rails_admin and are configured via a rails_admin block in their respective model.rb files.

	the two logs attached show a 4x difference in request processing time with and without using the config/included_models functionality.

	the first log traces the calls made to rails_admin config as models are loaded (look for ra_config). looks like death by a thousand cuts.

Analyze a .map file and output sizes of each pod, gem, the app itself, RubyMotion, iOS, as well the specific symbol sizes largest to smallest

	#!/usr/bin/env ruby

	# analyze a .map file and output sizes of each pod, gem, the app itself, RubyMotion, iOS
	# also output functions (as per the -n option) sorted by size (high to low)
	#
	# change *_PREFIX constants and/or path_regexes to fit your specifics
	#
	# requires that RubyMotion is patched in order to generate the mapfile:
	# /Library/RubyMotion2.26/lib/motion/project/builder.rb

crosebrugh / simple_form-error-notification-to-flash.rb

Last active August 29, 2015 14:05

Vector simple_form error notification to flash

	# A https://github.com/plataformatec/simple_form puts it's alert box inside of the form instead
	# of using the flash object. This may look clunky depending on how the various backgrounds are set up on the page.

	# E.g. in a view, f.error_notification puts the alert within the form instead of above
	# it where flash info goes as per the layout
	<%= simple_form_for(resource, as: resource_name, url: confirmation_path(resource_name), html: { method: :post }) do \|f\| %>
	<%= f.error_notification %>
	<%= f.full_error :confirmation_token %>

	<div class="form-inputs">
