I use delayed job to carry out background tasks in my app. It does some stuff and then sends a mail. This is an example of the code block preformed as a delayed job.
def task
# do stuff
AppMailer.post.some_template(#variable)
end
This has been working fine, I have a template in the correct directory some_template.text.plain.erb. I have started seeing this raise a MissingTemplate exception and this stops the delayed job and tries again after a given time (as expected when exceptions are raised in delayed job). Some cases this will fail 2 or 3 times and then deliver successfully, other cases there will be no exception raised. How can a template not exist then be found successfully upon the next attempt?
The error is looking for a template .erb is the plain.text.erb causing this problem. Any ideas why this is causing an intermittent problem? I have tried wrapping the sending of the mail in a rescue block as I would rather not send the mail than raise an exception.
def task
# do stuff
begin
AppMailer.post.some_template(#variable)
rescue ActionView::MissingTemplate => e
# do stuff
end
end
But the exception is still raised. Does delayed job do anything that might stop this rescue block working?
Here is the stack trace

I know there are a couple of problems here but any advice would be appreciated.
It's hard to say from just what you've posted but with Delayed Job Mailer errors I would typically check for two things:
That your workers are being restarted when you deploy new code, so that they are using the latest version of your app.
Are the arguments you're passing to the Mailer method used to retrieve records? If so be careful that records don't change or disappear between the job being created and the job being worked. Consider passing in exactly the attributes you need to build the mail if this is the case.

In my Ruby on Rails application I have model that looks like this:
class Schema < ActiveRecord::Base
has_many :schema_items
def self.from_cache(schema_id)
schema = Rails.cache.read("schema_#{schema_id}")
unless schema
schema = Schema.where(id: schema_id).includes(:schema_items).first
Rails.cache.write("schema_#{schema_id}", schema) if schema
end
schema
end
end
I'm using this class method in other class which is called by Sidekiq worker. From time to time it returns the following error:
NotImplementedError
Using google I found this issue in redis_store gem: https://github.com/redis-store/redis-store/issues/74
But they fix this bug. My app is hosted on Heroku and I'm using the RedisCloud. Any ideas how can I solve this?

A couple options without being able to go into the Pro code:
Error you found is redis-store related, try memcached
Try moving the cache to memcached, it should be a simple and non-disruptive action, cost-free on simple plans, and see if the problem goes away, or changes, could be useful for hunting the core bug down
memcache is a better caching service anyway for simple key-value stuff,
The worker you linked is not a part of the stack trace
You showed the ResponseCreatorWorker, but that does not appear in the stack trace. What appears is ResponseProcessorWorker, maybe link that worker instead?
Are you sure you are running the code you are running?
Mike Perham says that the Sidekiq backtrace doesn't match the version you have given him, and the wrong worker is in the stack trace? Are you really sure the server is updating? Review the deployment log and log in to the worker with heroku run bash and inspect a couple of key files, make sure nothing is off with the platform.
Can you rescue it? :D
It should be pretty safe to put in a rescue that catches NotImplementedError, tries once again, and logs a record of it into the logs. Update gems when appropriate and when warnings disappear open a whiskey and celebrate.
Put something like this in your model:
def wrap_me_scotty
yield
rescue NotImplementedError => e
warn "#{e} :-("
yield # try once more, let it explode if no joy
end
and then wrap Rails.cache calls
def self.from_cache(schema_id)
schema = wrap_me_scotty{ Rails.cache.read("schema_#{schema_id}") }
unless schema
schema = Schema.where(id: schema_id).includes(:schema_items).first
wrap_me_scotty{ Rails.cache.write("schema_#{schema_id}", schema) } if schema
end
schema
end
I was running tests using spork with no problem, however, occasionally I have to restart the spork server to get it to recognize newly added routes. On this occasion, I restarted the spork server, and I am now getting the following error message whenever I run any tests:

Additional restarts of the spork server have not changed anything. Any thoughts on what may be causing this/how to fix it? Thanks
EDIT: Added code from spec_helper.rb
Spork.each_run do
ActiveSupport::Dependencies.clear
ActiveRecord::Base.instantiate_observers <--- This is line 56
load "#{Rails.root}/config/routes.rb"
Dir["#{Rails.root}/app/**/*.rb"].each { |f| load f }
end if Spork.using_spork?
This block was added so that I would no longer need to reset the spork server to get it to recognize changes to routes, however, I made this change earlier today and have successfully run many tests since then.
Observers were removed from Rails 4. Attempting to instantiate them will just not work. The code example you have is probably from Rails 3.
Remove that line. Nothing bad will happen.
As part of my rails project, we are going to use a daemon as a message queue listener to execute commands coming from a Rails RESTful webservice front end.
For ease of prototyping, we are using the Daemons gem to create a very simple daemon. Right now, it's super simple. Here is the code:
require 'rubygems'
require 'daemons'
require File.expand_path('../../config/environment', __FILE__)
Daemons.run_proc('aeon_server') do
loop do
empires = Empire.all
sleep(5)
end
end
Basically, it requires the things for daemons, then requires my Ruby environment, then launches in to the daemon. The daemon simply attempts to query everything from the Empires table. Then it sleeps and does it again.
When it goes to execute 'all', I get the following exception:

Any idea why ActiveSupport is throwing this exception? Are there additional steps I need to "bootstrap" my rails environment in to the daemon, beyond just requiring the environment?
There're some intricacies with regard to file descriptors when the process is forked/spawned/whatever-it-is-called-on-windows.
Try to reinstantiate a logger after you do Daemons.run_proc('aeon_server') with Rails.logger = ActiveSupport::BufferedLogger.new('/path/to/log')
I am using ruby 1.8.7 and rails 2.3.5 and I am getting this weird message "Can't dup NilClass" when I try to run the code below
rr = Node.find(params[:id])
puts rr.inspect
rr.destroy
The application prints out the correct information about the node, when I try to do the exact same thing in script/console it works fine!!! I have no clue what is going on ..
I upgraded my application to rails 2.3.8 but no luck what so ever :(
Please help,

Is it possibly somehow confusing your Node class with this one?
http://apidock.com/ruby/REXML/Node
I'm having problems with my functional tests involving paperclip and attachments. I'm using the fixture_file_upload method to fake the attachment uploads.
My tests intermittently give me the error below (or one similar to it), generated by a factory_girl call to create the object containing the attachment, which is in my setup block.
#asset = Factory(:asset, :item => fixture_file_upload('test.png','image/png'))
However, even though the setup block is run for every test in the final, this error isn't generated for every test. Running a single test in the file (which calls the setup block and the above method) runs fine. It's just with multiple tests that I get the error (and it's not always the same depending on how many tests are run.) So there's some sort of conflict with multiple calls to fixture_file_upload.
Anyone have any ideas of how to get around this problem? Thank you.

Looks like this issue: https://github.com/thoughtbot/paperclip/issues/270. There is a possible workaround in the article.
