[Ruby on Rails] I want to get the URL of the image saved in Active Storage

Task

If I thought that I could easily get the URL of the image saved in ActiveStorage, I unexpectedly used it, so make a note.

`image_Erb using tag`


<%= image_tag recipe.image.variant(resize: '200x200').processed %>

`Actual html`


<img src=\"http://localhost:3000/rails/active_storage/representations/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBCZz09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--d3fb1fe3b017a6060dd908f2463551e10cfbacb0/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaDdCam9MY21WemFYcGxTU0lNTWpBd2VESXdNQVk2QmtWVSIsImV4cCI6bnVsbCwicHVyIjoidmFyaWF0aW9uIn19--306915654d885f72af9e428f63f831384a058376/01.png\" />

I just want the URL without using image_tag.

Conclusion

I got it by using rails_representation_url.

`Validate on console`


irb(main):001:0> Rails.application.routes.url_helpers.rails_representation_url(recipe.image.variant(resize: "200x200").processed, only_path: true)
=> "/rails/active_storage/representations/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBCZz09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--d3fb1fe3b017a6060dd908f2463551e10cfbacb0/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaDdCam9MY21WemFYcGxTU0lNTWpBd2VESXdNQVk2QmtWVSIsImV4cCI6bnVsbCwicHVyIjoidmFyaWF0aW9uIn19--306915654d885f72af9e428f63f831384a058376/01.png "
