hi, i try to use rufus in rails 5 ,but there have a problem:

$scheduler.at st.sc_time do
somemethod()

Hello,

what is the complete error message?

Please give me something like:

NoMethodError: undefined method `[]' for nil:NilClass
./lib/fugit/nat.rb:41:in `parse'
./spec/nat_spec.rb:27:in `block (4 levels) in <top (required)>'
/Users/jmettraux/.gem/ruby/2.2.5/gems/bundler-1.13.5/lib/bundler/cli/exec.rb:74:in `load'
/Users/jmettraux/.gem/ruby/2.2.5/gems/bundler-1.13.5/lib/bundler/cli/exec.rb:74:in `kernel_load'
/Users/jmettraux/.gem/ruby/2.2.5/gems/bundler-1.13.5/lib/bundler/cli/exec.rb:27:in `run'
/Users/jmettraux/.gem/ruby/2.2.5/gems/bundler-1.13.5/lib/bundler/cli.rb:332:in `exec'

Also, what version of Ruby? What operating system? What version of rufus-scheduler?

Thanks in advance.

Also, you are talking about Rails 5. Are you implying it works with Rails 4 or 3 ?

[jmettraux]

Also, what do you mean by "it's blocked here"? The whole application is blocked?

hi, ruby version 2.2
this is code

          puts "-----------------------"
          puts runtime
          puts st.sc_time
          puts "-----------------------"
          if st.sc_time>runtime then
            $scheduler.at st.sc_time do
              puts '=================='
              puts 'startjob...'
              files=AutoUploadfile.where(:xmid=>session[:pr_id],:ntype=>0)
              puts files.count
              puts '=================='
            end
          end
       end
       $scheduler.join

and there is no error message , just no reponse：

Other question: what Ruby server are you running your Rails 5 on top of? Passenger? Unicorn? Puma? Webrick?

[lovingyu]

Puma

[jmettraux]

JRuby or MRI Ruby? What version?

[lovingyu]

ruby 2.2.4p230 (2015-12-16 revision 53155) [x64-mingw32]
windows 10

files=AutoUploadfile.where(:xmid=>session[:pr_id],:ntype=>0)
this worked fine in other program, but in here it doesn't work ,i wanna kown why .

[jmettraux]

Remove the

$scheduler.join

line and try again. This line is only for standalone scripts, not for schedulers running inside of the Rails application.

Please tell me what happens (or not) then.

[lovingyu]

it's worked ! thanks a lot .

You're welcome. Have a nice day!
