Ruby Forum Ruby on Rails > Problems creating emails using ActionMailer

Hi Guys,

I am having some issues with ActionMailer in a new project I am
working on.
I am getting the following message:
"Due to changes in ActionMailer you need to provide the mailer_name as
well as the template name"
That seemed simple enough, but it doesn't work.

The problem I see is similar to this:
http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/517ff90aa97a11a2/b89fef43b89c3e51?lnk=gst&q=render_message#b89fef43b89c3e51

I am also using Acts_As_Authenticated.
I have tried commenting out the rails_gem_version as suggested in the
above post.

When I create an email using
body "some text goes here"
I get the email fine.

So I tried to render the email using:
render "user_notifier/signup_notification"
I get the following error
can't convert Symbol into String

I'm not even sure where to look to solve this one.  If any further
info is needed (code etc) please let me know.  I didn't want to make
the post too massive.

Your help is much appreciated.

render in ActionMailer isn't quite like in a controller, you have to
pass in a hash of options. It's also private so you shouldn't be
calling really.
If you want to change the template rendered stick

template 'some_other_template'

in your mailer method. if you need to change the directory in which it
looks then I believe you need to use mailer_name ie

class SomeMailer < ActionMailer::Base
   mailer_name 'foo_mailer'
   def something
     template 'bar'
   end
end
will render foo_mailer/bar

Fred

Thanks for the feedback Fred,

Just to clarify, I am not trying to render a template in a different
folder (everything is in the "as expected" folders).  When I don't
have a render specified, I get the "need to specify the mailer_name"
error.
So In Summary:
views/user_notifier/signup_notification.erb is the render file
models/user_notifier.rb is the ActionMailer class (Class UserNotifier)

In regards to your suggestions the code is now as follows (for the
mailer class):

class UserNotifier < ActionMailer::Base
  mailer_name "user_notifier"
  def signup_notification(user)
    setup_email(user)
    template "signup_notification"
  end
  <snip>
end

Any Thoughts?
Thanks
~Ben

Gah! I forgot to paste the error message.

It is:
wrong number of arguments (1 for 0)

app/models/user_notifier.rb:5:in `mailer_name'
app/models/user_notifier.rb:5
app/models/user_observer.rb:5:in `after_create'

Hi All,

I tried setting the mailer_name using:
mailer_name="user_notifier"

I now am back to the start - getting the error
"Due to changes in ActionMailer, you need to provide the mailer_name
along with the template name"

Any Ideas?
Thanks
~Ben

I am getting the same error.  I tried to change the directory to
another invalid one.. sure enough it raised an error saying the
template could not be found.  But I cannot get past the "can't dup
NilClass " error

here's my model code

class BalUserNotify < ActionMailer::Base
  mailer_name='bal_user_notify'
  def change_password(bal_user, password, url=nil)
    setup_email(bal_user)

    # Email header info
    @subject += "Changed password notification"

    # Email body substitutions

    body[:name] = "#{bal_user.firstname} #{bal_user.lastname}"
    body[:login] = bal_user.login
    body[:password] = password
    body[:url] = url || BalUserSystem::CONFIG[:app_url].to_s
    body[:app_name] = BalUserSystem::CONFIG[:app_name].to_s

    render :file => 'bal_user_notify/change_password'
  end
....

  def setup_email(bal_user)
    @recipients = "#{bal_user.email}"
    @from       = BalUserSystem::CONFIG[:email_from].to_s
    @subject    = "[#{BalUserSystem::CONFIG[:app_name]}] "
    @sent_on    = Time.now
    @headers['Content-Type'] = "text/plain;
charset=#{BalUserSystem::CONFIG[:mail_charset]}; format=flowed"
  end
end

has anybody successfully upgraded to rails 2.0 and succeeded with
converting the mailer models/views?

here's the stack errors too

In actionmailer render is private. Don't call it (besides, you're
rendering the default so it's completely superfluous)

when i remove that line i am back to this line

Due to changes in ActionMailer, you need to provide the mailer_name
along with the template name.

  render "user_mailer/signup"
  render :file => "user_mailer/signup"

If you are rendering a subtemplate, you must now use controller-like
partial syntax:

  render :partial => 'signup' # no mailer_name necessary

your mailer_name =  should be self.mailer_name = 'foo' or mailer_name
'foo' (mailer_name = 'foo' just creates a local variable)

If you are going to call render yourself, you need to give it a body
option (the set of assigns, eg :body => {:name => 'Bob'}, or in your
case :body => body since you have built that.)

Ok, i have changed the mailer_name = "foo" to self.mailer_name =
"bal_user_notify"

and the class/function to
class BalUserNotify < ActionMailer::Base
  self.mailer_name='bal_user_notify'

def change_password(bal_user, password, url=nil)
    setup_email(bal_user)

    # Email body substitutions

    body[:name] = "#{bal_user.firstname} #{bal_user.lastname}"
    body[:login] = bal_user.login
    body[:password] = password
    body[:url] = url || BalUserSystem::CONFIG[:app_url].to_s
    body[:app_name] = BalUserSystem::CONFIG[:app_name].to_s

    render :file => 'bal_user_notify/change_password', :body=>body
  end
end

I am still getting this error.

This isn't making much sense - that error is only raised if there is
no / in the file you are trying to render (which there is). and if
everything is in the default place you shouldn't need to do anything
(i've got several mailers like that - no setting mailer_name, no calls
to render). Might you have a plugin which is messing things up?

i found out that it was an issue with some localization functions that 
were
a part of the SaltedLoginGenerator.

I removed the localization files from being included and hard-coded the
wording in the forms (since i am a 1-language site for now) and that
worked.

self.mailer_name="foo" and then no render lines in the methods

thanks for your help!

Hi Ethan,

I am also running the salted login generator.
Could you take me through what you did to remove the localization files?

Your help would be much appreciated.

~Ben

One thing when i had them set up was in my environment.rb file there 
were 2
lines
#require 'localization'
#Localization::load_localized_strings
as you can see i commented them out.

When you do this, your forms and logins will all work still but the 
issue
now will be the localization strings in your forms will now show a 
variable
name instead of the value.  What I did was find all of these tags and
replace them.

form_helper
input_helper
message_helper
title_helper

basically doing a find of all *_helper in the .rhtml files and replacing
with the wording/text I preferred.  Since i am an english language only 
site
it wasnt a big deal to me to have them hard coded.  Hopefully it wont be 
too
tedious for you.

I hope that works for you.  Let me know if you run into problems.

Ethan

Hi,

I got problem in extracting email header like

From: hhhh@hotmail.com
To:   gggg@hotmail.com
Subject: jjjjjjj

Actually i already fetch a the received mail using fectmail to a
ForActionMailer.txt file. But the text is contain plain text and
attachment. I already extracting out the attachment which is lmx file.
Currently i want to extract out the header from ForActionMailer.txt file
and append to the lmx file.

Is it possible to do so. Because in forum, people keep talking 
aboutsending email but nevermention about receiving email.

Thanks

Thanks for pointing me in this direction Ethan!

Changing all my localizations to hard-coded strings would have been a 
lot of work for me so I edited the lib/localization.rb and commented out 
these lines:

ActionMailer::Base.module_eval <<-EOL
  private
  def render_message(method_name, body)
    initialize_template_class(body).render_file(method_name + 
"_#{CONFIG[:default_language]}")
  end
EOL

and that did the trick for me.
