自定义路线参数和form_with不使用参数

如何解决自定义路线参数和form_with不使用参数

我正在尝试为地址分配一个自定义ID，因此不容易猜测记录（对于想要添加和更改其他人地址的人）。出于某种原因，尽管我可以使用正确的路径创建记录，但是form_with的编辑路径似乎没有使用自定义资源参数。

routes.rb

resources :deladdresses,param: :delid

_form.html.erb

<%= form_with model: deladdress,class: "mt-4" do |f| %>
  <%= render "shared/error_messages",resource: f.object %>

  .. lots removed for clarity ...

  <%= f.hidden_field :country,value: "Australia" %>
  <%= f.hidden_field :ordernum,name: :ordernum,value: @order %>
  <%= link_to order_path(@order.ordernum) do %>
    <button class="btn btn-secondary">Back</button>
  <% end %>
  <%= f.button "Save",id: 'submit',class: "btn btn-primary" %>
<% end %>

谁来自我的new.html.erb和edit.html.erb：

<%= render "form",deladdress: @deladdress %>

deladdress.rb

class Deladdress < ApplicationRecord

  before_save :add_del_id

  belongs_to :user
  has_many :orders

  def add_del_id
    randchars = ("a".."z").to_a.sample(8).join
    time = DateTime.Now.strftime("%H%M%s")
    self.delid = "#{time}-#{randchars.upcase}"
  end

end

deladdress_controller.rb

class DeladdressesController < ApplicationController
  before_action :find_my_order

  def show
    # Collect the delivery address for the order
    # Do we want to collect and store these per customer?
  end

  def new
    if current_user
      @savedaddresses = Deladdress.where(user: current_user)
    end
    @deladdress = Deladdress.new
  end

  def edit
    @deladdress = Deladdress.where(delid: params[:delid]).first
  end

  def create
    @deladdress = Deladdress.create(deladdress_params)
    @deladdress.user = current_user
    if @deladdress
      @order&.update(deladdress: @deladdress)
      redirect_to order_path(@order.ordernum),notice: "Address added"
    else
      render :new
    end
  end

  def update
    @deladdress = Deladdress.where(delid: params[:delid]).first
    if @deladdress.update(deladdress_params)
      @order.update(deladdress: @deladdress)
      redirect_to order_path(@order.ordernum),notice: t(".updated")
    else
      render :edit
    end
  end

  private

  def deladdress_params
    attributes = [:first_name,:last_name,:address,:apartment,:city,:state,:country,:postcode,:ordernum,:delid]
    params.require(:deladdress).permit(*attributes)
  end

  def find_my_order
    @order = find_order
  end

end

当我转到下面的URL http://localhost:5000/deladdresses/112750-UBTYOJGK/edit时，我看到那里有delid。但是，当我查看将要尝试提交的表格时，会看到以下内容。 ID为5，而不是112750-UBTYOJGK。

<form class="mt-4" action="/deladdresses/5" accept-charset="UTF-8" data-remote="true" method="post">
  <input type="hidden" name="_method" value="patch">
  <input type="hidden" name="authenticity_token" value="XXXXXXXXXXXX">
  <button name="button" type="submit" id="submit" class="btn btn-primary">Save</button>
</form>

我显然缺少了一些东西，但是我真的不知道什么。

在此先感谢您可能提供的任何帮助。

解决方法

您可以将表单的网址传递给表单助手，如下所示：

1. 调用编辑表单的位置：

<%= render "form",deladdress: @deladdress,url: deladress_path(@deladress.delid) %>

1. 在哪里调用新表单：

<%= render "form",url: deladresses_path %>

，然后以表单本身的形式：

<%= form_with model: deladdress,url: url,class: "mt-4" do |f| %>
...
