Paperclip files not being attached to actionmailer. No such file or directory

Question

I am trying to attach a paperclip avatar image to an email, however it doesn't seem to realize it is an image that I am attaching, but when I place the url in my browser it finds the image. I am not sure if it is because of the random numbers that paperclip has at the end or not.

In my Usermailer

attachments.inline['avatar.jpg'] = File.read("localhost:3000#{@user.avatar.url(:medium)}")

In my email

<%= image_tag attachments['avatar.jpg'].url %>

The url it spits out is(The picture is a random stock photo for testing)

localhost:3000/system/users/avatars/000/000/026/medium/Maximus_Minimus_food_truck_Seattle_Washington.JPG?1397942965

Answer 1

You can use the Asset pipeline to attached the actual file path. Have not tested.

"#{Rails.root}/#{<YourAppName>::Application.assets.find_asset('avatar.jpg').pathname}"

You can find the answer here

Answer 2

Here's my model looks like

class Petition < ApplicationRecord
  has_attached_file :contract
end

In mailer, I attached this contract file like this. Hope this helps.

def send_invitation(petition)
  attachments[petition.contract_file_name] = File.read(petition.contract.path)
  mail(
    to:       @petition.email,
    subject: t('mailer.send_invitation')) do |format|
    format.html { render 'send_invitation' }
end

Answer 3

I think you are supposed to use

attachments.inline['avatar.jpg'] = @user.avatar.data
