carrierwave

问题 I have a document model that consists of PDF files. Because I don't need to manipulate the PDFs in any way, I'm attempting to use CarrierWaveDirect without its processing step, which I believe is downloading and re-uploading the files.

问题 How do I apply a drop shadow to my images saved with carrierwave? I can't find any examples on how to do this. Update: Example for adding a shadow to images with CSS. You can remove the padding and margin if you don't like the white 1px border around the image. It looks nice though... .dropSmallShadow { box-shadow: 0 1px 5px rgba(0, 0, 0, 0.255); margin-left: 1px; padding: 1px; } Best regards Asbjørn Morell 回答1: My recommendation is to not add the border/dropshadow in the image (since you may

问题 I'm trying to upload to amazon s3 an existing image on facebook or twitter from an user that has just signed up in my application, but some validation don't let me save the user object, throws: Image is invalid. I thought that was for my extension_white_list but I removed it and it's keeping saying Image is invalid.

问题 My app is hosted on Heroku and I am wondering if its possible to upload a file not to the public/ folder on Heroku but directly to - say - Linode My app uses both Heroku and Linode. The two talk to each other via web-service requests.

问题 I'm using CarrierWave and Cloudinary to upload multiple pictures to my blogposts. I upload them from my browser. This happens with the use of a file field in the post form. <%=file_field_tag "images[]", type: :file, multiple: true %> When the form is being submitted, a picture instance is created for each one of the images and the image is being uploaded to Cloudinary. def create @post = Post.new(post_params) if @post.save if params[:images] params[:images].each do |image| @post.pictures
