问题 When I sort the name column of a model in ActiveAdmin , I get output such as the following: Apples Icicles Zebras iMacs iPhones where the uppercase and lowercase letters appear to be sorted separately. I prefer to display sorted columns in the following manner: Apples Icicles iMacs iPhones Zebras with no unnatural case sensitivity. I tried using the line column :name, sortable: 'my_model.name.downcase' to mitigate the issue, but this throws an ActiveRecord::StatementInvalid error. How can I

问题 I need a table whos name is Campus. But rails interprets that as plural, messing everything up. So I did a little research and they suggest to add an inflection like this: ActiveSupport::Inflector.inflections do |inflect| inflect.singular /^(campus)(es)?$/i, '\1' inflect.plural /^(campus)$/i, '\1es' end I have added this in the initializers/inflection.rb file. I created a new migration to drop the table and create a new one again called Campus, expecting to have the problem solved, but now I

问题 In short, is it possible to build an Amazon clone without substantial modification to Spree? 回答1: it is indeed possible. If you do, don't use spree as an engine, just use the whole sourcecode as itself. If you use it as an engine, you'll end up overriding so much features of spree that you will be lost totally! Also use and extend the tests that come with spree. You will however loose the ability to update spree, because you will have to change a lot of stuff in the core. 来源： https:/

So what is the scope of this Ruby code if it doesn't have
