问题
I checked out the questions that have already been asked on this subject, "There are many", but I do not find a solution.
I have a fairly large task and the files name is 'sample_employee_data.rake'... so here goes:
namespace :db do
desc "Fill database with sample Employee data"
task populate: :environment do
@gender = ["Male", "Female"]
@role = ["Staff", "Support", "Team_Leader", "Manager", "Director"]
@marital_status = ["Single", "Married"]
@primary_position = ["Household", "Job Developer", "Job Coach",
"Job Support", "Personal Care"]
@trained_position = ["Household", "Job Developer", "Job Coach",
"Job Support", "Personal Care"]
@emer_contact_relationship = ["Friend", "Brother", "Sister", "Aunt",
"Uncle", "Cousin", "Nephew", "Father",
"Mother", "Spouse"]
def randomDate(params={})
years_back = params[:year_range] || 5
latest_year = params[:year_latest] || 0
year = (rand * (years_back)).ceil +
(Time.now.year - latest_year - years_back)
month = (rand * 12).ceil
day = (rand * 31).ceil
series = [date = Time.local(year, month, day)]
if params[:series]
params[:series].each do |some_time_after|
series << series.last + (rand * some_time_after).ceil
end
return series
end
date
end

I ran:
rake sample_employee_data.rake
and I got this flag:
rake aborted!
Don't know how to build task 'sample_employee_data.rake'
home/me/.rvm/gems/ruby-1.9.3-p385@rails3212/bin/ruby_noexec_wrapper:14:in 'eval'
home/me/.rvm/gems/ruby-1.9.3-p385@rails3212/bin/ruby_noexec_wrapper:14:in '<main>'
Can anyone spot the problem ... my apologies for such a long file.
Thanks.
回答1:
There's a couple things going on here.
When you run $ rake sample_employee_data.rake you're asking rake to rake your file - but rake responds to tasks:
$ rake some_namespace:some_task_in_that_namespace
You're also using a custom .rake file rather than the conventional Rakefile - which is fine, but this means you need to tell rake explicitly that you're not using its default Rakefile.
$ rake --rakefile your_custom_rake_file.rake some_task
So in your case, you need to issue a rake command like so:
$ rake --rakefile sample_employee_data.rake db:populate
