如何批量将多行代码粘贴到Rails控制台？寻求高效替代方案

Ugh, I feel your pain—pasting long scripts line by line into the Rails console is such a drag. Luckily, there are a few easy ways to skip that hassle:

• Load a script file right in the console
  Save your full script (like that Article class you wrote) into a .rb file, say article_setup.rb. Then hop into the Rails console and run:

  load 'article_setup.rb'
  

  (If the file isn't in your project root, just use the full path to it.) This will execute the entire file in the Rails environment, just as if you'd typed every line yourself.

• Run it directly with rails runner
  If you don't need to mess around in the console after running the script, skip opening the console entirely. From your terminal, run:

  rails runner 'article_setup.rb'
  

  This runs the script in the full Rails context without launching the interactive console—perfect for quick, one-off runs.

• Paste safely with multi-line mode
  If you really have to paste directly into the console, try triggering multi-line mode first. Type the first line of your script (like class Article) and hit enter—the console will show > prompts, letting you paste the rest of the code without it executing line by line. Or wrap your whole script in a begin...end block before pasting; the console will wait for the closing end before running anything.

Any of these methods should save you from the tedious line-by-line grind.
