I've got a Rails3 mailer layout that include images.
This ones are used like :
image_tag("emails/top.gif", :width => "700", :height => "10", :alt => "")
As of Rails 2, this images included the host and produced the expected result. However, since Rails3 the config.action_mailer.default_url_options seems to be ignored.
Is there anything I'm missing?
Update
my config/environment/development.rb include:
config.action_mailer.default_url_options = { :host => 'mydomain.tld' }
Needs to use config.action_mailer.asset_host = 'http://mysite.com' in your environment config file

I'm getting an error when attempting to change the :filename of my paperclip attachment to equal an attribute on the class I'm attaching the paperclip file to.
When I use "#{self.company_name}" it errors out. Apparently in this scope, "self" is not Company. When I wrote this line I assumed that self is the instance of Company that I'm uploading this attachment to. Any idea how I can fix this? The Paperclip docs say to use ":filename" but I'd like to use the value of Company.company_name instead.
class Company < ActiveRecord::Base
include AliasAttrs
has_attached_file :company_logo, {
:storage => :ftp,
:path => "/logos/#{self.company_name}",
:url => FTP_CONFIG[:access_host]+"logos/:filename",
:ftp_servers => [
{
:host => FTP_CONFIG[:host],
:user => FTP_CONFIG[:user],
:password => FTP_CONFIG[:pass],
:port => 21 # optional, 21 by default
}
]
}
end
Update
I tried using the advice found in this post: https://robots.thoughtbot.com/paperclip-tips-and-updates
But now I am getting the following error when starting my server:
undefined method `interpolations' for Paperclip::Attachment:Class (NoMethodError)
It looks like the syntax for interpolations has changed. Updated it and it worked. Add the following to your model or create a paperclip.rb file in config/initializers
Paperclip.interpolates :company_name do |attachment, style|
attachment.instance.company_name
end
I had successfully integrated comfortable mexican sofa CMS into an existing rails 4.1.2 application.
Now I want to upload images to heroku from s3 bucket.
Can anyone please tell the steps for that?
Sofa is using paperclip for attachments. So first, take a look here: http://www.rubydoc.info/gems/paperclip/Paperclip/Storage/S3
Then in initializers/comfortable_mexican_sofa.rb you'll find config.upload_file_options. This is how you'll override defaults.
config.upload_file_options = {
:storage => :s3,
:s3_credentials => ...
}
config.upload_file_options = {
:whiny => false,
:storage => :s3,
:s3_credentials => {"access_key_id" => ENV["S3_ACCESS_KEY_ID"], "secret_access_key" => ENV["S3_SECRET_ACCESS_KEY"]},
:bucket => ENV["S3_BUCKET_NAME"],
:s3_host_name => 's3 HOST NAME',
:path => "uploaded_files/:basename.:extension",
:styles => {:thumb => "850x850>" }
}
Give styles inside the config.upload_file_options which will take exact size of an image.
Which make more sense in uploading image else image pixels may vary.
The available configuration parameters are defined in paperclip, not comfy, and more information about there meaning can be found at:
http://www.rubydoc.info/github/thoughtbot/paperclip/Paperclip/Storage/S3
Just a note: Comfy has switched from Paperclip to ActiveStorage in 2017, so the answers are somewhat outdated.
I'm getting this error while generating pdf using wkhtmltopdf
undefined method `pdf_from_string' for #<WickedPdf:0x7f4b82a369c8>
my wicked_pdf.rb
WickedPdf.config = {
:wkhtmltopdf => '/usr/local/bin/wkhtmltopdf',
:layout => "pdf.html",
:margin => { :top=> 40,
:bottom => 20,
:left=> 30,
:right => 30},
:header => {:html => { :template=> 'layouts/pdf_header.html'}},
:footer => {:html => { :template=> 'layouts/pdf_footer.html'}}
# :exe_path => '/usr/bin/wkhtmltopdf'}
on command line
wkhtmltopdf google.com google.pdf
is working fine.
"pdf_from_string" means, that it makes pdf from STRING.
So to make this method work it should recieve string.
<WickedPdf:0x7f4b82a369c8> - it is an object.
It should look like this:
pdf_from_string("<p>some html code</p>")
You will get this message when calling pdf_from_string on the class itself, instead of an instance.
WickedPdf.pdf_from_string('<p>some html code</p>')
Will not work, however:
WickedPdf.new.pdf_from_string('<p>some html code</>')
will, because new returns an instance, which you could then call pdf_from_string on.
This is the same as this:
pdf_generator = WickedPdf.new
pdf = pdf_generator.pdf_from_string('<p>some html code</p>')
I'm trying to use ActionMailer without Rails in a project, and I want to use Haml for the HTML email templates. Anyone have any luck getting this configured and initialized so that the templates will be found and rendered? I'm currently getting errors like:
ActionView::MissingTemplate: Missing template new_reg/daily_stats/full with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html], :locale=>[:en]} in view paths "/home/petersen/new_reg/lib/new_reg/mailers/views"
To clarify, this is ActionMailer 3.0.4
Looks like the issue is that without the full Rails stack, Haml doesn't completely load, specifically the Haml::Plugin class. Adding require 'haml/template/plugin' after the normal require 'haml' line seems to solve the problems.
require 'haml/template/plugin' in the "configure do" block together with ActionMailer::Base.view_paths = "./views/" did it for me (Sinatra)
Not necessary in Rails -- but since you're using ActionMailer without Rails -- did you specify ActionMailer::Base.register_template_extension('haml')?
I'm seeing a similar issue and am using ActionMailer 3.0.3. register_template_extension does not exist in ActionMailer 3.
I'm using Sinatra. I've got mailer.rb (below) in APP_ROOT/lib and the views are located in APP_ROOT/views/mailer. This sends an email with a subject, the body is blank though.
require 'action_mailer'
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.view_paths = File.dirname(__FILE__)+"/../views/"
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'exmaple.com',
:user_name => 'user#exmaple.com',
:password => 'password',
:authentication => 'plain',
:enable_starttls_auto => true }
class Mailer < ActionMailer::Base
def new_comment_notifier(post,comment)
#post = post
#comment = comment
mail(:to => "user#example.com",
:subject => "new comment on: #{post.title}")
end
end
I'm writing a small Ruby program that will pull records from a database and send an HTML email daily. I'm attempting to use ActionMailer 3.0.3 for this, but I'm running in to issues. All the searching I've done so far on using ActionMailer outside of Rails applies to versions prior to version 3. Could someone point me in the right direction of where to find resources on how to do this? Here's where I am so far on my mailer file:
# lib/bug_mailer.rb
require 'action_mailer'
ActionMailer::Base.delivery_method = :file
class BugMailer < ActionMailer::Base
def daily_email
mail(
:to => "example#mail.com",
:from => "example#mail.com",
:subject => "testing mail"
)
end
end
BugMailer.daily_email.deliver
I'm definitely stuck on where to put my views. Every attempt I've made to tell ActionMailer where my templates are has failed.
I guess I should also ask if there's a different way to go about accomplishing this program. Basically, I'm doing everything from scratch at this point. Obviously what makes Rails awesome is it's convention, so is trying to use parts of Rails on their own a waste of time? Is there a way to get the Rails-like environment without creating a full-blown Rails app?
After some serious debugging, I found how to configure it.
file mailer.rb
require 'action_mailer'
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => "domain.com.ar",
:authentication => :plain,
:user_name => "test#domain.com.ar",
:password => "passw0rd",
:enable_starttls_auto => true
}
ActionMailer::Base.view_paths= File.dirname(__FILE__)
class Mailer < ActionMailer::Base
def daily_email
#var = "var"
mail( :to => "myemail#gmail.com",
:from => "test#domain.com.ar",
:subject => "testing mail") do |format|
format.text
format.html
end
end
end
email = Mailer.daily_email
puts email
email.deliver
file mailer/daily_email.html.erb
<p>this is an html email</p>
<p> and this is a variable <%= #var %> </p>
file mailer/daily_email.text.erb
this is a text email
and this is a variable <%= #var %>
Nice question! It helped me to understand a bit more how Rails 3 works :)
It took me a while to get this to work in (non-)Rails 4. I suspect it's just because I have ':require => false' all over my Gemfile, but I needed to add the following to make it work:
require 'action_view/record_identifier'
require 'action_view/helpers'
require 'action_mailer'
Without the above code, I kept getting a NoMethodError with undefined method 'assign_controller'.
After that, I configured ActionMailer as follows:
ActionMailer::Base.smtp_settings = {
address: 'localhost', port: '25', authentication: :plain
}
ActionMailer::Base.default from: 'noreply#example.com'
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.logger = Logger.new(STDOUT)
ActionMailer::Base.logger.level = Logger::DEBUG
ActionMailer::Base.view_paths = [
File.join(File.expand_path("../../", __FILE__), 'views', 'mailers')
# Note that this is an Array
]
The templates go in lib/<GEM_NAME>/views/mailers/<MAILER_CLASS_NAME>/<MAILER_ACTION_NAME>.erb (MAILER_ACTION_NAME is the public instance method of your mailer class that you call to send the email).
Lastly, don't forget to put this in your spec_helper:
ActionMailer::Base.delivery_method = :test
