Question

我试图在检查禁止选项时尝试将配置文件更新的时间保存转换为整数，但每当我查看数据库字段时， ban_time 为nil

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

其他所有内容都已正确保存。

更新：以下是用户的架构和模型。

模式

  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

模型

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

表格

<%= form_for @user do |f| %>
    <% if @user.errors.any? %>
        <div class="alert alert-danger">
            <ul>
                <% @user.errors.full_messages.each do |m| %>
                    <li><%= m %></li>
                <% end %>
            </ul>
        </div>
    <% end %>

    <div class="field">
        <%= f.label "Korisničko ime:" %>
        <%= f.text_field :username, class: "form-control" %>
    </div>

    <div class="field">

    <div class="field">
        <%= f.label "Potvrda lozinke:" %>
        <%= f.password_field :password_confirmation, class: "form-control" %>
    </div>

        <h3>Administratorska podešavanja</h3>

        <div class="field">
            <%= f.label "Rank:" %>
            <%= f.text_field :rank, class: "form-control" %>
        </div>

        <div class="field">
            <%= f.label "VIP:" %>
            <%= f.check_box :vip %>
        </div>

        <div class="field">
            <%= f.label "Banovanje člana:" %>
            <%= f.check_box :banned %>
        </div>

        <div class="field">
            <%= f.label "Razlog:" %>
            <%= f.text_area :bandesc, class: "form-control" %>
        </div>

        <div class="field">
            <%= f.label "Vremenski period (dana):" %>
            <%= f.text_field :ban_remaining_days, class: "form-control" %>
        </div>

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

<% end %>

Answer 1

        <%= f.check_box :banned %>

...将返回＆＃39; 0＆＃39;如果false或＆＃39; 1＆＃39;如果true

并且没有params[:banned] params[:user][:banned]或user_params[:banned]

所以改变

if !params[:banned].nil?

进入

if user_params[:banned] == '0'

无法在Rails模型中节省当前时间
