列出rails应用程序中的可用生成器

Question

如何在generators应用中获取可用Rails的列表，包括来自devise等内容的宝石？ （类似于rake -T列表rake tasks）

Answer 1

我明白了。命令是

rails generate

输出是这样的：

Usage: rails generate GENERATOR [args] [options]
General options:
  -h, [--help]     # Print generator's options and usage
  -p, [--pretend]  # Run but do not make any changes
  -f, [--force]    # Overwrite files that already exist
  -s, [--skip]     # Skip files that already exist
  -q, [--quiet]    # Suppress status output

Please choose a generator below.

  assets
  controller

  inherited_resources_controller
  integration_test
  mailer
  migration
  model
  observer
  performance_test
