I can see that mimemagic failed to compile in your screenshot but I do not see why. It could be related to it needing to find freedesktop. I got around this easily on Mac by doing brew install shared-mime-info and it knew where to find the library.

Thanks, that helps a lot. I think we should upgrade our Dockerfile. I'm testing it now. Email Required, but never shown. The Overflow Blog. Podcast Making Agile work for data science. Stack Gives Back Featured on Meta.

This will give you the path where that utility is installed. Then, in your environment config file, let Paperclip know to look there by adding that directory to its path. If you are dealing with pdf uploads or running the test suite, you'll also need to install GhostScript.

If you're on Ubuntu or any Debian base Linux distribution , you'll want to run the following with apt-get:. The Unix file command is required for content-type checking. This utility isn't available in Windows, but comes bundled with Ruby Devkit , so Windows users must make sure that the devkit is installed and added to the system PATH.

To test, you can use the image below:. Either of these methods will give your Rails setup access to the file. If you're trying to use features that don't seem to be in the latest released gem, but are mentioned in this README, then you probably need to specify the master branch if you want to use them.

Or you can use the Rails migration generator: rails generate paperclip user avatar. Paperclip will wrap up to four attributes all prefixed with that attachment's name, so you can have multiple attachments per model if you wish and give them a friendly front end. These attributes are:. NOTE: Post-processing will not even start if the attachment is not valid according to the validations.

Your callbacks and processors will only be called with valid attachments. If you have other validations that depend on assignment order, the recommended course of action is to prevent the assignment of the attachment until afterwards, then assign manually:. You should ensure that you validate files to be only those MIME types you explicitly want to support. Thanks to a report from Egor Homakov we have taken steps to prevent people from spoofing Content-Types and getting data you weren't expecting onto your server.

NOTE: Starting at version 4. Paperclip will raise an error if you do not do this. This keeps Paperclip secure-by-default, and will prevent people trying to mess with your filesystem. NOTE: Also starting at version 4. This validation will prevent content type spoofing. This validation will only add validation errors to the form.

It will not cause errors to be raised. This can sometimes cause false validation errors in applications that use custom file extensions. In these cases you may wish to add your custom extension to the list of file extensions allowed for your MIME type configured by the mime-types gem:. Global defaults for all your Paperclip attachments can be defined by changing the Paperclip::Attachment. These will get merged into Paperclip::Attachment. An example:. Another option is to directly modify the Paperclip::Attachment.

Paperclip defines several migration methods which can be used to create the necessary columns in your model. There are two types of helper methods to aid in this, as follows:. Vintage syntax such as t. If you would like to use Paperclip with another storage, you can install these gems along side with Paperclip:. For example, using that :path , you may have a file at.

NOTE : This is a change from previous versions of Paperclip, but is overall a safer choice for the default file store. You may also choose to store your files using Amazon's S3 service. To do so, include the aws-sdk gem in your Gemfile:. You can find more information about configuring and using S3 storage in the Paperclip::Storage::S3 documentation. Files on the local filesystem and in the Rails app's public directory will be available to the internet at large.

If you require access control, it's possible to place your files in a different location. You will need to change both the :path and :url options in order to make sure the files are unavailable to the public. Both :path and :url allow the same set of interpolated variables. Paperclip supports an extensible selection of post-processors.
