'Rake db:seed' command returning http error 500 in heroku

Question

I'm having a problem while deploying an api in Rails on Heroku. In the development environment it works perfectly and my data placed through db:seed is in the database. After doing the deploy on heroku, I ran the db:migrate command and my bank is empty and when running db:seed, the server returns http 500 error. Am I doing any wrong process? is there a possibility to use db: seed in heroku?

Product.destroy_all
   ProductCategory.destroy_all
   Restaurant.destroy_all
   Category.destroy_all


   path_image = 'public/images/categories/mexican.jpg'
   c = Category.create(id: 1, title: 'mexican')
   c.image.attach(io: File.open(path_image), filename: 'mexican.jpg')

   path_image = 'public/images/categories/italian.jpeg'
   c = Category.create(id: 2, title: 'italian')
   c.image.attach(io: File.open(path_image), filename: 'italian.jpeg')

   path_image = 'public/images/categories/japonese.jpeg'
   c = Category.create(id: 3, title: 'japanese')
   c.image.attach(io: File.open(path_image), filename: 'japanese.jpeg')

   path_image = 'public/images/categories/vegan.jpeg'
   c = Category.create(id: 4, title: 'vegan')
   c.image.attach(io: File.open(path_image), filename: 'vegan.jpeg')

Answer 1

尝试，heroku运行rails db：seed

Answer 2

first make sure you do heroku rails db:migrate then do heroku rails db:seed .

If you are writing directly on heroku terminal you don't need the "heroku" just rails db:migrate and rails db:seed
