How do I keep paperclip from deleting attachments from an acts_as_paranoid model?

阅读更多关于 How do I keep paperclip from deleting attachments from an acts_as_paranoid model?

问题 I have a model with a couple of different image attachments managed by paperclip. Recently we changed the behavior of the model so it could be soft-deleted and revived using acts_as_paranoid. Everything works great except that when we soft delete the model, paperclip is deleting the attachments as well.

Set content type in S3 when attaching via Paperclip 4?

问题 I'm trying to attach CSV files to a Rails3 model using paperclip 4.1.1, but I'm having trouble getting the content-type as reported by S3 to be text/csv (instead I am getting text/plain ). When I subsequently download the file from S3, the extension is getting changed to match the content-type instead of preserving the original extension (so test.csv is downloaded as test.txt). From what I can see, when you upload a file, the FileAdapter will cache the content-type on creation with whatever

问题 I know that Heroku's dyno gets refreshed each time a deploy is made so is there anyway I can have my files persistent or there's no other way but use services like amazon S3? I use paperclip to handle file upload and most of the files will be in pdf. 回答1: It would be best to use S3 or another service. Ephemeral filesystem Each dyno gets its own ephemeral filesystem, with a fresh copy of the most recently deployed code. During the dyno’s lifetime its running processes can use the filesystem as

阅读更多关于 How to set the size of an image within CKeditor in Ruby On Rails according to the picture model?

问题 This could be a duplicate question but I doubt it. I have the following situation: I have a ruby on rails apllication with two widely used gems: paperclip and ckeditor (which is working with paperclip). I want the size of the image that I upload in the Ckeditor screen to be resized depending on the type of 'post'. Right now there's not a button that can help with that in the Ckeditor or anything, though it does upload the different type of sizes I set in the picture.rb model: class Ckeditor:

Using Delayed Paperclip With S3 Direct Upload

阅读更多关于 Using Delayed Paperclip With S3 Direct Upload

问题 I'm using Delayed Paperclip alongside direct uploads to S3. My model is called Photo and its attachment is image . Images are uploaded to S3 using JavaScript from the Photo form. The file is stored in the location that Paperclip expects the original image to be located, and the file details are saved to hidden fields. When the form is submitted, these attributes are written to the Photo model: image_file_name image_file_size image_content_type Because writing these attributes alone doesn't
