Rails在carrierwave中查找存储文件本地URL

Question

Working on a project that use a gem named OcrSpace to perform ocr on image uploaded by carrierwave .

After a button is clicked, the text in the image would be shown in the website.

Here's the code:

<%= image_tag( @resume.attachment_url) %>
<div id="cool"> </div>


<button onclick="myFunction()">Try it</button>

<% require 'ocr_space' resource = OcrSpace::Resource.new(apikey: "xxxxxxxxx") %>

<% result = resource.clean_convert file: @resume.attachment_url %>

<script>
function myFunction() {
    document.getElementById("cool").innerHTML = <%= result %>;
}
</script>

However, I got this error

No such file or directory @ rb_sysopen - /uploads/resume/attachment/3/_____2018-07-19___9.15.42.jpg

It seems that the file path is incorrect

Can anyone help me, thanks.

Answer 1

use

@resume.attachment.path

instead of @resume.attachment_url

url will not give you a local path to open as a file
