一、创建数据表

创建模型

php artisan make:model Question -m

修改生成数据迁移文件 questions_table.php

public function up()
{
   Schema::create('questions', function (Blueprint $table) {
       $table->increments('id');
       $table->string('title');
       $table->text('content');
       $table->integer('user_id')->unsigned();
       $table->integer('comments_count')->default(0);
       $table->integer('followers_count')->default(1);
       $table->integer('answers_count')->default(0);
       $table->string('close_comment', 8)->default('F');
       $table->string('is_hidden', 8)->default('F');
       $table->timestamps();

{
   return [
       'title' => 'required|min:3|max:196',
       'content' => 'required|min:20'
   ];
}

创建控制器

php artisan make:controller QuestionsController --resource

use Auth;
use App\Question;

public function __construct()
{
   $this->middleware('auth')->except(['index','show']);
}

   return view('questions.create');
}

public function store(StoreQuestionRequest $request)
{
   $data = [
       'title' => $request->get('title'),
       'content' => $request->get('content'),
       'user_id' => Auth::id()
   ];
   $question = Question::create($data);
   return redirect()->route('questions.show',[$question->id]);
}

public function show($id)
{
   $question = Question::find($id);
   return view('questions.show', compact('question'));
}

注册路由:routes/web.php
