elixir - Phoenix : Requiring IEx in only :dev and :test for entire project

Question

我是 Elixir/Phoenix 的新手，我想知道是否有办法基本上 require IEx用于 IEx.pry以与在 Ruby/Rails 中相同的方式，您可以添加类似

group :test, :development do
  gem 'pry', require: 'pry'
end

这将允许您 binding.pry基本上在任何文件中，而无需包含 require 'pry'
我发现必须 require IEx在任何 Controller 、模型、 View 等上，我想调试很乏味。

Answer 1

您可以使用 web/web.ex文件。

A module that keeps using definitions for controllers, views and so on.

This can be used in your application as:

use App.Web, :controller
use App.Web, :view

The definitions below will be executed for every view, controller, etc, so keep them short and clean, focused on imports, uses and aliases.

就放 require IEx当您需要它用于 Controller 、模型等时。

defmodule App.Web do
  def model do
    quote do
      ...
      require IEx
    end
  end
  def controller do
    quote do
      ...
      require IEx
    end
  end
end
