如何将种子图像数据传递到Rails视图中？

Question

I seeded my Rails db with the following for Posts: title, description, body, and image. For image I used data in the assets. So for example in the seed file I have:

post_image: '/images/main.image.jpg'

I'm able to hit all the other data in the views doing the typical:

<%= post.title %>

How do I pull in the image? I've tried the following to no avail:

• <%= asset_path('post.post_image')%>. Nothing appears
• <%= asset_url('post.post_image')%>. I get http://localhost:3000/post.main.image.jpg
• <%= image_tag('post.post_image')%>. I get a small icon with Post next to it but not a full image.
• <%= image_tag @post_image%>. I get a small icon but not a full image.
• <%= image_alt(post.post_image) %>. I get at main.image.jpg present

Did I seed incorrectly or am I just using the wrong helper to get the image?

Answer 1

Yeah I seeded incorrectly. Image_tag will hit images under the asset pipeline. Did a db:reset after I fixed the seed file to just be: post_image: 'main.image.jpg'. Correct code is:

<%= image_tag post.post_image %>
