Getting an error from saving an entry

display_error.rb

# Validations may cause errors
# since if an object is required to have certain values
# and saved without them it will not be saved to the database.

# Here I am creating a method that will accept an object and attempt to save it
# it will also display the relevant errors

def check_for_errors(obj)
  if (obj.save)
    puts "save was successful"
  else
    puts "Save failed"
    obj.errors.messages.each { |e| puts e }
  end

end

# Let's say this is a completely valid entry, and it will save properly
new_entry = Object.new(:name => "I'm an object" :description => "I will go to the database")

# Now we pass the object to the method to save and check for errors
check_for_errors(new_entry)

# The expected output will be
##########################################
# save was successful


# Now i'm just going to create an object with just a name
# and lets assume that it needs both name and description
invalid_entry = Object.new(:name => "I am an invalid object")

# Now we passed the invalid entry to the method
check_for_errors(invalid_entry)

# The expected output will be
##########################################
# save failed
# description
# can't be blank
