Example how to write seeds

[pycckuu]

Hello,

could you please provide a minimal example of how to populate the database, assuming the table and the fields exist. Usual rails example doesn't work.

country_list = [
  [ "Germany", 81831000 ],
  [ "France", 65447374 ],
  [ "Belgium", 10839905 ],
  [ "Netherlands", 16680000 ]
]

country_list.each do |name, population|
  Country.create!( name: name, population: population )
end

Thank you

I had to add the code inside a class extending ActiveRecord so for example your code would be:

class Country < ActiveRecord::Base
   # ...
  Country.create!( name: name, population: population )
end
