无法在 Rails 模型中保存当前时间

Question

每当检查 canned 选项时，我试图节省转换为整数编号的配置文件的时间，但是每当我查看数据库字段时， ban_time nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil。 /p>

def update
    find_user

    if !params[:banned].nil?
        @user.ban_time = Time.now.to_i
        @user.save
    end

    if @user.update(user_params)
        redirect_to @user, notice: "Profil je uspešno ažuriran."
    else
        render "edit"
    end
end

其他所有内容都正确保存。

更新：这里是用户的架构和模型。

架构

  create_table "users", force: :cascade do |t|
    t.string   "username"
    t.string   "email"
    t.string   "password_digest"
    t.datetime "created_at",         null: false
    t.datetime "updated_at",         null: false
    t.string   "location"
    t.date     "birthdate"
    t.string   "rank"
    t.boolean  "banned"
    t.text     "bandesc"
    t.boolean  "vip"
    t.integer  "ban_time"
    t.integer  "ban_remaining_days"
    t.integer  "bug_report_time"
  end

型号

class User < ApplicationRecord

    has_secure_password

    validates :username, presence: true, uniqueness: true, format: { with: /\A[a-zA-Z0-9]+\Z/},
                            length: { maximum: 10, minimum: 4 }
    validates :email, presence: true, uniqueness: true, length: { maximum: 50 }
    validates :password, presence: true, length: { maximum: 50, minimum: 4 }, if: :should_validate_pass?
    validates :password_confirmation, presence: true, if: :should_validate_conf?
    validates :location, presence: true, length: { maximum: 30 }
    validates :banned, presence: true, if: :ban_remaining_days?
    validates :ban_remaining_days, presence: true, numericality: { only_integer: true }, inclusion: { in: 1..365 }, if: :banned?
    validates :bandesc, presence: true, length: { maximum: 200, minimum: 20 }, if: :banned?

    def should_validate_pass?
        new_record? || password.present?
    end

    def should_validate_conf?
        new_record? || password_confirmation.present?
    end

end

    <div class="submit">
        <%= f.submit button_text, class: "btn btn-primary" %>
    </div>

<% end %>

Answer 1

        <%= f.check_box :banned %>

...如果false 将返回“0”，如果true 将返回“1”

没有params[:banned] 是params[:user][:banned] 或user_params[:banned]

所以改变

if !params[:banned].nil?

进入

if user_params[:banned] == '0'
