Question

我正在创建用户个人资料，并且试图在选择div中显示TITRE_ANNONCE，但出现错误：

试图获取非对象的属性

这是我的表格：

<div class="col-lg-4">
    <select class="contact_input" name="NOM_ARTICLE">
        @foreach($user as $annonce)
        <option> {{$annonce->TITRE_ANNONCE}}</option>
        @endforeach
    </select>
</div>

使用我的控制器：

public function voirprofile($id) {

    $user = DB::table('users')->
        join('article', 'article.id', '=', 'users.id')->
        join('annonce', 'annonce.ID_ARTICLE', '=', 'article.ID_ARTICLE')->
        where('users.id', $id)->
        get();

    return view('voirprofile') - > with('user', $user);
}

$ user包含他发布的所有“ nononce”的用户信息。这就是$ user返回的内容：

   }
]

这是我数据库中的正确数据。

当我在循环之后添加{{dd($annonce)}}时：

Answer 1

尝试

step=0
a_list=["A","B","C"]
for s in a_list:
    cursor = tweepy.Cursor(api1.user_timeline, id = s, tweet_mode='extended').items(3189)

    for tweet in cursor: 
        tw_text.append(tweet.full_text)
        created_at.append(tweet.created_at)
        rtws.append(tweet.retweet_count)
        favs.append(tweet.favorite_count)
        for h in tweet.entities['hashtags']:
            hashlist.append(h['text'])
        for u in tweet.entities['urls']:
            linklist.append(u['expanded_url'])
        try:
            medialist.append(media['media_url'] for media in tweet.entities['media'])
        except:
            pass 
        step+=1
        print('step {} completed'.format(step))

#preparing all the data for .executemany()               
    g = [(s,tw,crea,rt,fv,ha,li,me) for s in ['GameOfThrones'] for tw in tw_text for crea in created_at for rt in rtws for fv in favs for ha in hashlist for li in linklist for me in medialist] 
    cur.executemany("INSERT INTO series_data VALUES (?,?,?,?,?,?,?,?)", (g))
    con.commit()
    print('db updated')

Answer 2

使用可选助手

<div class="col-lg-4">
    <select class="contact_input"  name="NOM_ARTICLE" >
        @foreach($user as $annonce)
           <option> {{optional($annonce)->TITRE_ANNONCE}}</option> 
         @endforeach
    </select>
</div>

更改
{{$ annonce-> TITRE_ANNONCE}}
致
{{optional（$ annonce）-> TITRE_ANNONCE}}

为什么在显示数据时尝试获取非对象的属性？
