本文介绍了Laravel 5违反完整性约束的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我遵循了 laracast系列,并停留在某个位置. /p>
通过尝试提交博客帖子,我收到以下错误消息:
奇怪的是,已提交的文章存储在数据库中,并且也出现在我的文章视图中.
ArticlesController:
public function store(ArticleRequest $request) {
Auth::user()->articles()->save(new article($request->all()));
Article::create($request->all());
return redirect('articles');
}
商品型号:
public function user() {
$this->belongsTo('App\User'); //user_id
}
模式:
public function up()
{
Schema::create('articles', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id')->unsigned();
$table->string('title');
$table->text('body');
$table->timestamp('created_at');
$table->timestamp('published_at');
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
});
}
你知道例外的原因是什么吗?
解决方案
您可以尝试省略此行
Article::create($request->all());
因为您已经将文章保存为
Auth::user()->articles()->save(new Article($request->all()));
I followed a laracast series and stuck at some point.
I got the following error message by trying to submit a blog post:
The strange thing is, that the submitted article is stored to the DB and also appears in my articles view.
ArticlesController:
public function store(ArticleRequest $request) {
Auth::user()->articles()->save(new article($request->all()));
Article::create($request->all());
return redirect('articles');
}
Article Model:
public function user() {
$this->belongsTo('App\User'); //user_id
}
Schema:
public function up()
{
Schema::create('articles', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id')->unsigned();
$table->string('title');
$table->text('body');
$table->timestamp('created_at');
$table->timestamp('published_at');
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
});
}
Any idea what's the reason for the exception?
解决方案
You can try to leave out this line
Article::create($request->all());
since you are already saving the article with
Auth::user()->articles()->save(new Article($request->all()));
