我是编码和stackoverflow的新手，所以我希望我要问的问题不会太愚蠢 我正在尝试做的是在标题中：用户登录（电子邮件，密码）后，他们将被重定向到新表单，可以在其中填写姓名，个人简历和图片。 一切按计划进行，直到他们点击提交并遇到两个问题：

1 /不考虑新数据 2 /重定向错误

注册后，用户将被重定向到“ profiles /：id / edit”。提交表单后，它将重定向到“ user /：id”，该名称不存在。

它不应该重定向到控制器中的profile＃update吗？

这是我的不同代码：

1 /路线

Rails.application.routes.draw do
  devise_for :users
  root to: "pages#home"
  # For details on the DSL available within this file,see http://guides.rubyonrails.org/routing.html
  resources :jam_sessions,only: [:show,:index,:new,:create] do
    resources :spots,:create,:new]
    resources :messages,only: [:create]
  end
  resources :participations,only: [:create,:update]

  resources :profiles,:edit,:update]
  resources :dashboards,only: [:index,:show]


  resources :reviews,only: [:create]


  mount actionCable.server => "/cable"

  get 'users/:id',:to => 'profiles#edit',:as => :user

  patch 'profiles#edit',:to => 'profiles#update'
end 

2 / profiles_controller

class ProfilesController < ApplicationController
  def show

    @user = User.find(params[:id])
    @reviews = Review.where(receiver_id: @user.id)
    @instruments = UserInstrument.where(user_id: @user.id)
    @participations = Participation.where(user_id: @user.id)
    date = Time.now

    if @participations != nil
      @jam_sessions = []

      @participations. each do |participation|
        spot = Spot.find_by(id: participation.spot_id)
        @jam_sessions << JamSession.find_by(id: spot.jam_session_id)

      end
      @future_jam_sessions = []
      @past_jam_sessions = []
      @jam_sessions.each do |jam_session|
        if jam_session.starts_at > date
          @future_jam_sessions << jam_session
        else
          @past_jam_sessions << jam_session
        end
      end
    else
      puts "no jam"
    end
  end

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

  def update
    @user = User.find(params[:id])
    @user.update(user_params)
    raise
    if @user.save
      redirect_to profiles_path(@user)
    else
      render "new"
    end
  end
  private

    def user_params
      params.require(:user).permit(:first_name,:last_name,:bio)
    end
end

3 / application_controller

class ApplicationController < actionController::Base
  before_action :authenticate_user!,except: [:home,:show]

  before_action :configure_permitted_parameters,if: :devise_controller?
  def configure_permitted_parameters
    # For additional fields in app/views/devise/registrations/new.html.erb
    devise_parameter_sanitizer.permit(:sign_up,keys: [:first_name,:bio])
    # For additional in app/views/devise/registrations/edit.html.erb
    devise_parameter_sanitizer.permit(:account_update,keys: [:username])
  end

  def default_url_options
    { host: ENV["DOMAIN"] || "localhost:3000" }
  end

end

4 /用户模型

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable,:lockable,:timeoutable,:trackable and :omniauthable
  devise :database_authenticatable,:registerable,:recoverable,:rememberable,:validatable
  has_many :user_instruments,dependent: :destroy
  has_many :instruments,through: :user_instruments
  has_many :messages,dependent: :destroy
  has_one_attached :photo,dependent: :destroy
  has_many :reviews_written,class_name: "Review",foreign_key: :writer_id
  has_many :reviews_received,foreign_key: :receiver_id
  has_many :jam_sessions,dependent: :destroy

  def profile_picture
    if photo.attached?
      photo.key
    else
      "avatar-unknown.png"
    end
  end

  def full_name
    "#{first_name} #{last_name}"
  end
end

5 /编辑视图

<%= simple_form_for(@user) do |f| %>
  <%= f.input :first_name %>
  <%= f.input :last_name %>
  <%= f.input :bio %>
  <%= f.input :photo,as: :file %>
    <%= f.submit 'Update profile' %>
<% end %>

谢谢！ 奥利维尔
