rails link path and routing error when model singular and plural name are the same (e.g. equipment, species) - 


<%= link_to t('.new', :default => t("helpers.links.new")), new_equipment_path, :class => 'btn btn-primary' %>

i have above code in view, getting following error when clicking link: no route matches {:action=>"show", :controller=>"equipment"}

my routes file contains:

resources :equipment resources :workouts match ':controller(/:action(/:id))(.:format)'

why trying access show action?

here entries routes:

 equipment_index /equipment(.:format) equipment#index post /equipment(.:format) equipment#create new_equipment /equipment/new(.:format) equipment#new edit_equipment /equipment/:id/edit(.:format) equipment#edit equipment /equipment/:id(.:format) equipment#show put /equipment/:id(.:format) equipment#update delete /equipment/:id(.:format) equipment#destroy

this issue has cropped before , related how rails scaffolding generates new.html.erb file models have names 'equipment' both singular , plural.

if inspect form_for in new.html.erb file you'll see equipment_path in link_to @ bottom. these models singular==plural names refers route show action, hence error message.

the advice along lines of 'avoid model names if can' or involves bit of messing around config/initializers/inflections.rb file force plural version of model name. of course end app odd sounding references models: 'equipments' isn't nice work (and later on 'fix' it, messing things again).

to keep model name grammatically correct, need fix form_for i.e.:

<% form_for(@equipment, :url=> {:action=>'create'}) |f| %>

and link_to:

<%= link_to 'back', equipment_index_path %>

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
