How to determine if an array is saved in rails?

Question

In my seed.rb

  puts 'DEFAULT Categories'
  categories = Category.create([{name:'cat1'},{name:'cat2'}, {name: 'cat3'} ])
  if categories.save
    puts "categories saved"
  else
    puts "categories save failed"
  end

I use this to set the default categories but the problem is that I can't if categories.save to see if all category item get saved and hence the seed.rb get passed So, how can I see if an array get saved? (All of its elements) Thanks

Answer 1

if categories.all?(&:save)
  puts "categories saved"
else
  [...]
end

Answer 2

Use create! instead of create. It'll raise an an exception if it fails to save.

Answer 3

.create is creating the record. So, when you get to your if statement nothing happening because the save already happened during the create.

Change your .create to a .new, and you will be able to check if the save happened successfully:

puts 'DEFAULT Categories'
categories = Category.new([{name:'cat1'},{name:'cat2'}, {name: 'cat3'} ])  
if categories.save  
  puts "categories saved"  
else  
  puts "categories save failed"  
end  

Answer 4

if categories.all.each(&:persisted?)
  puts "categories saved"
else
  [...]
end
