Restrict access to images in Rails app

由 旧时模样 提交于 2019-12-18 08:55:45
问题 I have rails project. In my project I load images on server (rails 3 + paperclip + devise + cancan). I want to limit access to files (for example, the original image can be viewed only by the administrator). How should I do it? 回答1: If you are limiting by an attribute in your database then one way would be to serve the image via a controller. It's not the most performant but it is secure. I haven't tried this out, but if you were serving the image from a URL like /images/picture_of_mickey

It looks very simple functionality and i also know that i can do it using code behind (e.g. controlname.visible=false etc.),but since

问题 Does anybody have specifics on how to connect an Android application to MongoDB running on Azure roles? -- Hi, I have MongoDB replica set running on multiple Azure roles in the Cloud Service. I have used the mongo-azure library on GitHub to create the role instances and have them running in Azure.
