Question

自从我使用Rails做了很多工作已经有几年了，而且我没有Rails 5.1.6的经验。虽然我能够通过种子文件和Rails控制台保存数据，但我无法从HTML表单中保存。在提交时，我看到身份验证令牌和params出现在浏览器的URL栏中并重新呈现表单，而不是保存。

唯一不寻常的是我在Docker容器中开发，但是我在5.1.4中编写的最后一个应用程序使用相同的Dockerfile和Docker-Compose文件，它正常运行。

我的控制器：

class UsersController < ApplicationController
  before_action :find_user, only: [:show, :edit, :update]

  def index
  end

  def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    if @user.save
      redirect_to @user
    else
      render :new
    end
  end

  def show
  end

  def edit
  end

  def update
    if @user.update_attributes(user_params)
      redirect_to users_url
    else
      render :edit
    end
  end

  private
    def user_params
      params.require(:user).permit(:last_name, :first_name, :category, :phone_number, :email, :password, :password_confirmation)
    end

    def find_user
      @user = User.find(params[:id])
    end
end

观点：

<%= form_with model: (@user) do |f| %>
      <%= f.label :first_name %>
      <%= f.text_field :first_name %>

      <%= f.label :last_name %>
      <%= f.text_field :last_name %>

      <%= f.label :email %>
      <%= f.text_field :email %>

      <%= f.label :phone_number %>
      <%= f.text_field :phone_number %>

      <%= f.submit "Create user" %>
<% end %>

模特：

class User < ApplicationRecord
  belongs_to :account
end

“提交”后的网址：

我之前见过这种情况，但可能已经过了三年了，我不记得我是如何修理它的。任何想法都将不胜感激。

检查this 变化

<%= form_with model: (@user) do |f| %>

要

<%= form_with model: @user, local: true do |f| %>

Rails 5.1.6 params没有保存
