You can use

<pre><code>bundle exec rails runner "eval(File.read 'your_script.rb')"
</code></pre>

UPDATE:

What we also have been using a lot lately is to load the rails environment from within the script itself. Consider <code>doit.rb</code>:

<pre><code>#!/usr/bin/env ruby

require "/path/to/rails_app/config/environment"

# ... do your stuff
</code></pre>

This also works if the script or the current working directory are not within the rails app's directory.

blocks|key|1942310|text|在前面提到的这些方法中，没有一种看起来像您期望运行的独立脚本那样干净和理想(而不是通过<重定向获得评估或管道)，但最后这对我来说是完美的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1942311|(对于Rails+3)|1942312|在脚本的顶部插入：|1942313|#!/usr/bin/env+ruby

Of these approaches mentioned earlier, none seemed clean and ideal like you would expect a standalone script to run (not get eval-ed or piped via &lt; redirection), but finally this works perfect for me:

(for Rails 3)

Insert at the top of your script:

<pre><code>#!/usr/bin/env ruby

APP_PATH = File.expand_path(appdir = '/srv/staging/strat/fundmgr/config/application', __FILE__)
require File.expand_path(appdir + '/../boot', __FILE__)
require APP_PATH
# set Rails.env here if desired
Rails.application.require_environment!

# your code here...
</code></pre>

Of course, set your own Rails app path in the APP_PATH line.

That way, I can avoid having to enter any interactive <code>irb</code> or <code>rails c</code> and can test my script.rb from the shell prompt, before eg. scheduling it in crontab.

It smoothly supports command-line parameters, too, and minimizes the levels of wrappers before getting to your code.

Here's the hack I'm using:

<pre><code>rr() {
 rails_root="$(bundle exec rails runner "puts Rails.root")"
 rp="$(relpath "$1" "$rails_root")"
 bundle exec rails runner "eval(File.read '$rp')"
}
relpath() {python -c "import os.path; print os.path.relpath('$1','${2:-$PWD}')";}
</code></pre>

Example:

<pre><code>cd ~/rails_project/app/helpers
rr my_script.rb
</code></pre>

Based on @moritz's answer here. I changed it, since the working directory for <code>File.read</code> is the Rails project root.

I know this is some serious heresy, using python to help a ruby script. But I couldn't find a <code>relpath</code> method built into ruby.

Consider creating a rake task.
For code that I need to create records or support migrations, for example, I often create a rake task like that from <a href="https://stackoverflow.com/a/42498691/1038034">this answer</a>. For example:
In <code>lib/tasks/example.rake</code>:
<pre><code>namespace :example do
 desc &quot;Sample description you'd see if you ran: 'rake --tasks' in the terminal&quot;
 task create_user: :environment do
 User.create! first_name: &quot;Foo&quot;, last_name: &quot;Bar&quot;
 end
end
</code></pre>
And then in the terminal run:
<pre><code>rake example:create_user
</code></pre>

Is there a way to pass ruby file, foo.rb to rails console. Expected results would be after console starts rails environment to run file. 

Or any other way which would allow me to execute file in rails environment, triggered from command prompt.

Pass ruby script file to rails console

有没有办法把ruby文件，foo.rb传到rails控制台？预期的结果是在控制台启动rails环境来运行文件之后。或者任何其他允许我在rails环境中执行文件的方式，从命令提示符触发。
