How to build task 'db:populate'
Solution 1
Try renaming the file to sample_data.rake.
I was able to get your example working (replacing the internals of the task with a p statement) by putting your code in a file called testomatic.rake in lib/tasks.
Solution 2
I also had this problem. In Finder, the file name was sample_data.rake, but upon clicking "Get Info" for the file, I discovered the full file name was sample_data.rake.erb -- ensure that's not your problem.
Solution 3
Noobie with the same problem here - my branch was named differently than what I thought when I merged branches, so it reverted back to the old files before I had created my lib/tasks/sample_data.rake
file.
Simply going back and re-running git merge
with the correct name and push
ing to Heroku got it to work.
