rails whenver gem , running a command only if certain condition passes. - ruby-on-rails

Question

We are using whenever gem with rails on our project. I understand that we can schedule a command using whenever gem like this.
every 1.day, :at => '6:00 am' do
command "echo 'hello'"
end
but my problem is that i want to execute this command only when some condition is met. something like this.
every 1.day, :at => '6:00 am' do
if User.any_new_user?
command "echo 'hello'"
end
end
how can we achieve this with the whenever and rails?
One possible solution i can think of is that i create a runner for this and check that condition there.Something like:
every 1.day, :at => '6:00 am' do
runner "User.say_conditional_hello"
end
and inside my user model:
def self.say_conditional_hello
`echo "Hello"`
end
Any suggestions on this approach or any new approach will be really helpful.
Thanks in advance!.

if you want to only schedule the task if the condition is true then I don't think its possible you can schedule a task then when its time for running the task, the code can decide if it should be run or not, depending on your conditions

Yes this is one way of handeling this, however IMO the best behavior when using whenever is creating a rake task that checks for conditions then executes your code or perform your job
Something like:
Rake Task
namespace :user do
desc "description"
task check_for_new: :environment do
if User.any_new_user?
# code
end
end
end
in your schedule.rb file
every 1.day, :at => '6:00 am' do
rake "user:check_for_new"
end
