ruby on rails - wrong return value from service object -


i have controller use connection class (i made code simpler illustrate problem):

class invoicescontroller < applicationcontroller   def connect     @flow = flow.new(year: 2010, month: 10, day: 5)       @con = connection.new(@flow)         @con.connect     flash.now[:error] = "#{@con.connect}"    end   end   class connection   def initialize(obj)         @obj = obj       end    def connect         @result = [1].each |x|               case                  when (@obj.year > 1) && (@obj.day != 5)           break "result case1: #{@obj.day}"         when (@obj.year > 1) && (@obj.day == 5)           @obj.update_attributes(day: 6)           break "result case2 #{@obj.day}"                     end       end         return "#{@result}"   end end

the @flow object matches case 2 (day: 5), flash shows:

result case1: 6

when test connection class in console, return value correct.

maybe miss basic concept, thanks.

you're modifying object first time call connect (update_attributes(day: 6)), other case second time call it. if want call once, save return value in new variable , send flash.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
