Paperclip: How to store a picture in a Rails console?

Question

I tried storing a local image in a rails console.

Because I have many pictures in my local storage (I use crawler to download tons of pictures), I want to store them into a database, with the benefit of paperclip to do some image job, like thumbnail etc. If I use a webpage to save new pictures to database one by one, it will cost a lot of time. So I want to find a way in rails console (some code) that can batch save-picture-into-database.

I recommend taking more time with your question, including what you've tried and why you want to use "console" to store a local image... you'll get a higher chance of a reply by taking more time yourself. – Northwesterly

Answer 1

To further clarify @andrea's answer:

YourPaperclippedModelHere.new(:your_paperclip_field => File.new(path, "r"))

So if your model is called Image and your paperclip field is data:

Image.new(:data => File.new(path_to_your_file, "r"))

Answer 2

If this is the model:

class User < ActiveRecord::Base
  has_attached_file :avatar
end

then the following should work from the console:

>> User.create(:avatar => File.open('/path/to/image.jpg', 'rb'))

For those that are curious, 'rb' and 'r' in the File.open parameter are interchangable, as per: https://mcmap.net/q/410680/-file-opening-mode-in-ruby – Gigahertz

Answer 3

I dont know if it is what you want ... but to save an paperclip asset from console You could simple use a File instance . a.e.

Image.new :data=>File.new("/path/to/image.jpg","r")

ruby-1.9.2-p0 > Image.new NameError: uninitialized constant Image from (irb):2 from /home/mlzboy/.rvm/gems/ruby-1.9.2-p0/gems/railties-3.0.1/lib/rails/commands/console.rb:44:in start' from /home/mlzboy/.rvm/gems/ruby-1.9.2-p0/gems/railties-3.0.1/lib/rails/commands/console.rb:8:in start' from /home/mlzboy/.rvm/gems/ruby-1.9.2-p0/gems/railties-3.0.1/lib/rails/commands.rb:23:in <top (required)>' from script/rails:6:in require' from script/rails:6:in `<main>' – Trip

i tried use Image.new in rails console but it raise errors like above – Trip

In this case the File.new doesn't work, instead you shoult try this Image.create(:data => File.open('/path/to/image.jpg', 'r')) – Rapprochement

For future readers: Image is not built into Ruby or Rails; it is a model which would have to be defined just like User or Post in the app. Image here is being used as an example of an ActiveRecord model. – Mekka

Late Answer but hopefully it will work for others. You need to include.

File.new("#{Rails.root}/public/images/default_avatar.png", "r")
