javascript - Backbone js - Clean up data using regex on collection(models) before passing to view -


i'm using backbone populate dropdown list. changes api have resulted in data (option labels) coming unwanted data e.g "option foo - 00011222" instead of "option foo"

i'm planning use regex can show first characters before '-'

what best approach sanitizing data on collection before rendering view.

should done on view or on collection

if additional data can safely discarded, can use model.parse modify data receive:

parse model.parse(response, options)
parse called whenever model's data returned server, in fetch, , save. function passed raw response object, , should return attributes hash set on model.

for example, if want replace label field:

var data = [     {label: 'option foo - 00011222'},     {label: 'option foo2 - 00011222'} ];  var m = backbone.model.extend({     parse: function(data) {         data.label = data.label.replace(m.regexp, '');         return data;     } }, {     regexp: /\s*-.*$/ });  var c = backbone.collection.extend({     model: m });  var c = new c(data, {parse: true}); console.log(c.pluck('label'));

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
