问题 I'm trying to configure Paperclip to provide different missing images based on the instance's category attribute. Every category of the object has its own missing image.

How to set a file upload programmatically using Paperclip

由 一个人想着一个人 提交于 2019-11-27 17:06:14
I have a rake task to seed an application with random data using the faker gem. However, we also have images (like logos) that we want uploaded in this rake task. We already have Paperclip set up, but don't have a way to upload them programmatically in a rake task. Any ideas? theIV What do you mean by programmatically?

In this case,

I'm getting this error when I try to upload using paperclip with my rails blogging app. Not sure what it is referring to when it says "MissingRequiredValidatorError" I thought that by updating post_params and giving it :image it would be fine, as both create and update use post_params Paperclip::Errors::MissingRequiredValidatorError in PostsController#create Paperclip::Errors::MissingRequiredValidatorError Extracted source (around line #30): def create @post = Post.new(post_params) This is my posts_controller.rb def update @post = Post.find(params[:id]) if @post.update(post_params) redirect_to

Simple cropping with Paperclip

由 北战南征 提交于 2019-11-27 09:50:49
问题 I would like to crop images on upload using Paperclip to get square thumbs from the center of the original picture. I find out a method in documentation that seems to do exactly what I want: transformation_to(dst, crop = false) The problem is that I can't figure out where to use this method. It would be great to simply pass something as a parameter here: has_attached_file :picture, :styles => { :medium => "600x600>", :thumb => "something here" } 回答1: You only need to use # instead of > as a

Default_url in Paperclip Broke with Asset Pipeline Upgrade

由 大兔子大兔子 提交于 2019-11-27 07:25:35
I'm using Paperclip and have a default_url option like this for one of my attachments: :default_url => '/images/missing_:style.png' The asset pipeline obviously doesn't like this since the directories moved. What's the best way to handle this? I have two styles for this picture (:mini and :thumb). :default_url => ActionController::Base.helpers.asset_path('missing_:style.png') Then put the default images in app/assets/images/ Tested only on Rails 4. To make it work in production, we have to pass the name of an existing file to the asset_path helper. Passing a string containing a placeholder
