Question

当我尝试在表单上运行以下代码时，我收到以下错误消息：

<%= simple_form_for(@store) do |f| %>
    <%= f.error_notification %>
    <%= f.error_notification message: f.object.errors[:base].to_sentence
        if f.object.errors[:base].present? %>

    <div class="form-inputs">
        <%= f.input :location, required: true %>
        <%= f.input :branch_manager, required: true %>
        <%= f.input :store_ID, required: true %>
    </div>

    <div class="form-actions">
        <%= f.button :submit %>
    </div>
<% end %>

我检查了模型，控制器和模式，但store_ID与其他工作参数一致。我如何首先“定义”它？

schema.rb

以下是我的create_table "stores", options: "ENGINE=InnoDB DEFAULT CHARSET=utf8", force: :cascade do |t| t.string "location" t.string "branch_manager" t.integer "store_ID" t.datetime "created_at", null: false t.datetime "updated_at", null: false end

import UIKit

class CustomDisclosureIndicator: UIView {
    @IBInspectable
    public var color: UIColor = UIColor.darkGray {
        didSet {
            setNeedsDisplay()
        }
    }

    override func draw(_ rect: CGRect) {
        let context = UIGraphicsGetCurrentContext()

        let x = self.bounds.maxX - 3
        let y = self.bounds.midY
        let R = CGFloat(4.5)

        context?.move(to: CGPoint(x: x-R, y: y-R))
        context?.addLine(to: CGPoint(x: x, y: y))
        context?.addLine(to: CGPoint(x: x-R, y: y+R))
        context?.setLineCap(.square)
        context?.setLineJoin(.miter)
        context?.setLineWidth(2)
        color.setStroke()
        context?.strokePath()
    }
}

我认为你没有按照你说的那样进行迁移

＆＃34;我在生成所有内容后添加了ID字段，因此我不知道这是否会产生差异＆＃34;

有了这个，你应该解决：

rails db:migrate
