ruby on rails - ActionMailer -- NoMethodError: undefined method X for MyMailer:Class -


question: why method undefined if it's there?

details:

i have simple mailer class:

class productmailer < applicationmailer   def sample_email     mail(to: "me@example.com") # hardcode own email test   end end

and simple call productscontroller:

def sample_email   productmailer.sample_email().deliver_later   redirect_to @product, notice: 'email queued.' end

the email fails sent. using sidekiq process emails in background. sidekiq web ui shows failed jobs in tries page , can see why failed:

nomethoderror: undefined method `sample_email' productmailer:class

i tried rename method , restart server rails server none of removes error. not using namespaces.

question: why method undefined if it's there?

note: found out chance method is found if name notifybut maybe that's because i'm overwriting method actionmailer base class, don't know.

answer: restart sidekiq

i created mailer class before starting sidekiq, renamed sample_email method while sidekiq running, seems sidekiq doesn't recognize new methods on-the-fly.

i renamed method because used development environment, can change on fly...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
