    <p><strong>The code:</strong> I got the following piece of code in some HAML file.</p> <pre><code>= image_tag "https://s3.amazonaws.com/my_bucket/my_image.jpg" </code></pre> <p>It sends a request to s3 and loads the image in the browser. I got the following CORS configuration on the bucket:</p> <pre><code>&lt;CORSConfiguration&gt; &lt;CORSRule&gt; &lt;AllowedOrigin&gt;https://www.my_site.com&lt;/AllowedOrigin&gt; &lt;AllowedMethod&gt;GET&lt;/AllowedMethod&gt; &lt;/CORSRule&gt; &lt;/CORSConfiguration&gt; </code></pre> <p><strong>The problerm:</strong> In order to be able to manipulate the images on client side, the images are supposed to be served with the following headers:</p> <pre><code> Access-Control-Allow-Origin: https://www.my_site.com Access-Control-Allow-Methods: GET </code></pre> <p>but this does not happen.</p> <p><strong>The cause:</strong> My browser does not send 'Origin' request header, and therefore s3 does not respond with the desired headers.</p> <p><strong>Why I think that missing "Origin" header is the cause:</strong> Because the response of:</p> <pre><code>wget --server-response --header "Origin:https://www.my_site.com" "https://s3.amazonaws.com/my_bucket/my_image.jpg" </code></pre> <p>is the following:</p> <pre><code> HTTP/1.1 200 OK x-amz-id-2: kQV8HEChV1...QHmHC1Gt/ x-amz-request-id: A626...4A2 Date: Wed, 03 Jul 2013 10:10:38 GMT Access-Control-Allow-Origin: https://www.my_site.com Access-Control-Allow-Methods: GET Access-Control-Allow-Credentials: true Vary: Origin, Access-Control-Request-Headers, Access-Control-Request-Method ... </code></pre> <p>i.e. the 'Access-Control-Allow-Origin' and 'Access-Control-Allow-Methods' are present.</p> <p><strong>The supposed solution:</strong></p> <p>Is there a way to add manually the desired headers to the image_tag in the HAML file? Something like:</p> <pre><code>= image_tag "https://s3.amazonaws.com/my_bucket/my_image.jpg", :headers=&gt;["Origin"] </code></pre>

    1. COI'm having the exactly same issue. How did you manage that? Any solution? By the way, mine is working in Firefox but not in Chrome.

    2. COUnfortunately there is no explicit way to request certain headers. I've tried to load the images via javascript, but the browser does not allow to set that particular header ('Origin'), because of obvious security issues. We solved that problem with some server-side script, but I wasn't the person with the solution, so I got no implementation details (I can check the codebase, if you insist).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
