I have a custom template file that resides in a non-standard (for RoR) location. I wish to use this template for text format messages generated by a stand-alone script. I also wish to incorporate it into a new RoR app that is related to the existing script. The mailer and templates reside in this directory structure:
lib ├── hll_action_mailer │ ├── hll_action_mailer.rb │ ├── hll_th_forex_mailer │ │ ├── hll_th_forex_cacb_update_notice.rb │ │ ├── hll_th_forex_mailer.rb │ │ └── views │ │ ├── hll_th_forex_cacb_update_notice.text.erb │ │ └── hll_th_forex_commercial_rates_notice.text.erb

I have discovered that passing a do block after the call to the mail method discards any template_path and template_name keys passed in the argument list. See: ActionMailer::Base#mail should allow overriding template_name for default template rendering when a block is passed by betesh · Pull Request #18412 · rails/rails · GitHub. However I cannot seem to discover any way at all to use my custom template path and name with a do block.
I have tried this:
this_template_name = "hll_th_forex_commercial_rates_notice.text.erb"
this_template = File.join( "/", File.dirname( __FILE__ ),
"/views",
this_template_name )
mail( :to => recipients,
:from => fm_address,
:subject => subject,
) \
do |format|
format.text do
render( this_template )
end
end
``
But this causes this error:
Missing template home/byrnejb/Projects/Software/theHeart/code/hll_th_main/lib/hll_action_mailer/hll_th_forex_mailer/views/hll_th_forex_commercial_rates_notice.text.erb with {:locale=>[:en], :formats=>[:text], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in:
* "/home/byrnejb/Projects/Software/theHeart/code/hll_th_main/lib/hll_action_mailer/hll_th_forex_mailer"
* "/home/byrnejb/Projects/Software/theHeart/code/hll_th_main/app/views"
I considered the lack of a leading / on the reported path as the source of the problem but an inspection of the contents of this_template immediately before the call to render shows this:
do |format|
format.text do
puts( this_template.inspect ) render( this_template ) end end
``
which gives:
“/home/byrnejb/Projects/Software/theHeart/code/hll_th_main/lib/hll_action_mailer/hll_th_forex_mailer/views/hll_th_forex_commercial_rates_notice.text.erb”
So what is happening inside render? How do I specify a mailer template in a non-standard location in render or is that not possible and I must set an explicit default? well that does not work either:
class HllThForexMailer < ActionMailer::Base default( :template_path => Pathname.new( File.join( File.dirname( FILE ), “views” ) ).realpath.to_s ) . . . mail( :to => recipients, :from => fm_address, :subject => subject, :template_name => “hll_th_forex_commercial_rates_notice.text.erb” )
``
gives this:
Missing template /home/byrnejb/Projects/Software/theHeart/code/hll_th_main/lib/hll_action_mailer/hll_th_forex_mailer/views/hll_th_forex_commercial_rates_notice.text.erb with "mailer". Searched in:
* "/home/byrnejb/Projects/Software/theHeart/code/hll_th_main/lib/hll_action_mailer/hll_th_forex_mailer/views"
Which is at least what I expected. However the message says that it cannot find the template file. Yet when I do this using the exact path string copied from the ‘Missing template message’ I see this:
ls -l /home/byrnejb/Projects/Software/theHeart/code/hll_th_main/lib/hll_action_mailer/hll_th_forex_mailer/views/hll_th_forex_commercial_rates_notice.text.erb

So something is seriously screwed up with either what action-mailer is doing or with the error message it is reporting since the template file is exactly where AM says it could not find it.
How do I get this to work?
