在为用户设置了designgem之后，我如何才能在rails上创建帖子

Question

我正试图在RubyonRails上构建一个基本的User/Post应用程序，一切都很顺利，但后来我添加了设计宝石来为我创建登录/注册，现在我无法创建帖子。一旦用户登录，他们将被重定向到http://localhost:3000/posts.在那里他们可以点击"；添加新植物"；(关于植物的帖子(，并将它们带到http://localhost:3000/posts/new页在这里，表单已经启动并运行，用户可以填写标题和描述，然后点击创建帖子按钮，但它只是停留在这个页面上，什么也没发生。帖子甚至都没有保存。如果有人能告诉我如何解决这个问题，我将不胜感激！在我添加带有设计的用户表之前，这些帖子是正常创建的。

这就是当我点击创建帖子按钮时显示的内容。这是我的模式：

ActiveRecord::Schema.define(version: 2020_07_26_023022) do
create_table "posts", force: :cascade do |t|
t.string "title"
t.text "description"
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.integer "user_id"
end
create_table "users", force: :cascade do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["email"], name: "index_users_on_email", unique: true
t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
end
end

这是我的帖子控制器：

class PostsController < ApplicationController
before_action :find_post, only: [:show, :edit, :update, :destroy]
def index
@posts = Post.all.order("created_at DESC")
end
def show
end
def new 
@post = Post.new
end
def create 
@post = Post.new(post_params)
if @post.save
redirect_to @post 
else
render 'new'
end
end
def edit 
end
def update 
if @post.update(post_params)
redirect_to @post
else 
rend 'new'
end
end
def destroy 
@post.destroy
redirect_to posts_path
end
private 
def find_post
@post = Post.find(params[:id])
end
def post_params
params.require(:post).permit(:title, :description, :user_id)
end
end 

Answer 1

也许这可以帮助您…：

控制器内：

def create 
@post = Post.new(post_params)
@post.user = current_user # here You setting the user
if @post.save
redirect_to @post 
else
puts @post.errors # this should print errors to the console  
render 'new'
end
end

在型号中

module User
has_many :posts
...
end

module Post
belongs_to :user
...
end

Answer 2

似乎对Post的某些验证失败了。我建议在你的控制器上做这样的事情：

def create 
@post = current_user.posts.build(post_params)
if @post.save!
redirect_to @post 
else
render 'new'
end
end

如果问题确实在验证中，save!将立即失败，并且您可以进一步调试它。

我在日志中看到请求已完成。有可能帖子真的被创建了？你检查数据库了吗？
