Question

This may take some explanation so do bear with me.

I’m trying to access an image in Rails stored with Paperclip. The images can be accessed perfectly in a for loop, thus:

for a in @issue.articles
  image_tag a.image.url
end

Do note that @issue has no articles method; I’m not sure why that works. It does, however, have article1, article2, and article3; and each of those has the image in question.

If I try to access the image outside the loop with this code it fails, thus:

image_tag @issue.article1.image.url

Any advice would be hugely appreciated.

Answer 1

I believe the correct way is

@issue.articles.first.image.url

or for each of them

@issue.articles[0].image.url
@issue.articles[1].image.url
@issue.articles[2].image.url
