运行Rails db:Seed后，Rails 6.0 Seed.rb文件未保存到sqlite3数据库

Question

Rails 6.0(初级(运行rails db:seed --trace后，我的种子文件没有保存到我的数据库中

我得到以下输出：

** Invoke db:seed (first_time)
** Invoke db:load_config (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:load_config
** Execute db:seed
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke db:load_config 
** Execute db:abort_if_pending_migrations

因为它声明如果挂起迁移则中止。为了安全起见，我运行了rails-db:migrate，但它们都是最新的，所以什么都没做。

load_config中有什么我需要做的吗？

注意：在这个过程中，我在这个表中创建了两个条目，同时试图让它发挥作用。表中先前的条目会阻止种子工作吗？

下方的种子文件

def time_rand from = 0.0, to = Time.now
Time.at(from + rand * (to.to_f - from.to_f))
end
event_list = [
["My headline", 
"this is a very long description of text", 
"Physical Location", 
"Locations url", 
time_rand, 
"this is a shorter description of words", 
"https://www.ticketmaster.com/", 
"google maps url",
"123 Fake Street", 
"Brooklyn", 
"11123", 
"NY", 
"USA" ]
]
event_list.each do |headline, d_long, location_name, location_url, image_url, time, d_short, tickets_url, map_url, location_street, location_city, location_zip, location_state, location_country|
temp = Event.create(
headline: headline, 
description_long: d_long, 
location_name: location_name, 
location_url: location_url, 
time: time, 
description_short: d_short, 
tickets_url: tickets_url, 
map_url: map_url, 
location_street: location_street,
location_city: location_city,
location_zip: location_zip,
location_state: location_state,
location_country: location_country
)
temp.save
end

编辑：感谢Sebastian调用模型验证。尽管我认为我仍在完成验证，但这里的模型文件是：

class Event < ApplicationRecord
validates :headline, presence: true, length: { minimum: 3 }
validates :description_short, presence: true, length: { minimum: 3 }
validates :location_name, presence: true
validates :time, presence: true
end

多亏了Sebastian Palma建议使用byebug，我明白了：-我错过了params的计数，所以时间被赋予了一个字符串。-我在测试时间前也得到了零分，因此被验证拒绝了。我最终只是在某个时间值中进行了硬编码，以确保它最终通过。

经验教训：计算您的参数&使用byebug
