    <p>I am using carrier-wave to upload images. On upload I am creating thumbnails for the image which is done using Rmagick method, resize_to_fill like below.</p> <pre><code>version :thumb do process :resize_to_fill=&gt; [150, 150] end </code></pre> <p>Here is output of all the RMagick methods carrierwave <a href="http://carrierwave.rubyforge.org/rdoc/" rel="nofollow noreferrer">supports</a> (none of which I want):</p> <ol> <li><code>:resize_to_fill =&gt; [150,150]</code></li> </ol> <p><strong>This works fine on larger images but my smaller images are enlarged to 150 x 150.</strong> <img src="https://i.stack.imgur.com/R9oHc.png" alt=":resize_to_fill =&gt; [150,150]"></p> <ol start="2"> <li><code>:resize_to_fit =&gt; [150,150]</code></li> </ol> <p><strong>Again it was resized, I want it left alone!</strong></p> <p><img src="https://i.stack.imgur.com/0JHLn.png" alt=":resize_to_fit =&gt; [150,150]"></p> <ol start="3"> <li><code>:resize_to_limit =&gt; [150,150]</code></li> </ol> <p><strong>This one leaves it as is, but larger images are not cropped. They are resized to keep the aspect ratio.</strong></p> <p><img src="https://i.stack.imgur.com/7RdTn.png" alt="enter image description here"></p> <p><img src="https://i.stack.imgur.com/uQ45t.jpg" alt="enter image description here"></p> <p><strong>Here is the result I want and how my small and larger images should look.</strong></p> <p><img src="https://i.stack.imgur.com/gAiIC.jpg" alt="enter image description here"> <img src="https://i.stack.imgur.com/7RdTn.png" alt="enter image description here"></p> <p>How do this? I want smaller images to be left alone and crop only larger images to 150 x 150. Is there another method or options I can pass to resize_to_fill?</p>

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.
