Rails console - use image_tag method

Question

How can I execute a image_tag method in a Rails console

1. Run the console $ rails c

2. Load helpers

   include ActionView::Helpers

3. Execute the command

   image_tag('test.png')

I got a strange error.

Please help!

OK... I found the solution. The error is showing only in Rails 3 but I fixed it by setting the

  config.action_controller.asset_host = "http://..."
  config.action_mailer.asset_host = "http://..."

in my environemnt file (e.g. development.rb). Unbelievable!

This functionality is now part of a plugin https://github.com/xpepermint/js_erb.

Not sure why you're getting that error. It is strange.

But the Rails Console exposes the helper methods through the helper variable. So this should work:

helper.image_tag('test.png')
