无法从我的 Flask CRUD 应用程序从 mysql 表中检索数据，即使它被插入而没有任何错误

如何解决无法从我的 Flask CRUD 应用程序从 mysql 表中检索数据，即使它被插入而没有任何错误

这是python代码片段

@app.route('/oxygenadmin')
@is_logged_in
def oxygenadmin():
    cur=MysqL.connection.cursor()
    cur.execute("SELECT * FROM oxygen")
    data =cur.fetchall()
    cur.close()
    return render_template('oxygenadmin.html',oxygen=data)
    



@app.route('/insert',methods=['POST'])
@is_logged_in
def insert():
    if request.method == 'POST':
        name = request.form['name']
        contact = request.form['contact']
        email = request.form['email']
        place = request.form['place']

        cur = MysqL.connection.cursor()
        cur.execute("INSERT INTO oxygen(name,contact,email,place) VALUES (%s,%s,%s)",(name,place))
        MysqL.connection.commit()
        flash("Data inserted successfully",'success')
        return redirect (url_for('oxygenadmin'))
    return render_template ('oxygenadmin.html')

这是 html 片段

<div class="row">
            <div class="col md-12">
                <h2> Oxygen Details <button type="button" class="btn btn-success pull-right" data-toggle="modal" data-target="#mymodal">Enter New Data</button> </h2>

                <table class="table table-striped">
                    
                    <tr>
                        <th>ID</th>
                        <th>Name</th>
                        <th>Contact No.</th>
                        <th>Email</th>
                        <th>Place</th>
                        <th>Action</th>
                    </tr>
                {% for row in oxygen %}
                
                    <tr>
                        <td>{{row.0}}</td>
                        <td>{{row.1}}</td>
                        <td>{{row.2}}</td>
                        <td>{{row.3}}</td>
                        <td>{{row.4}}</td>
                        <td>
                            <a href="" class="btn btn-warning btn-xs" data-toggle="modal" data-target="#moDaledit">Edit</a>
                            <a href="" class="btn btn-danger btn-xs" onclick="return confirm('Are you sure you want to delete?')">Delete</a>


                        </td>
                    </tr>
                {% endfor %}
                </table>
            </div>
        </div>

还有……

<div id="mymodal" class="modal fade" role="dialog">
            <div class="modal-dialog">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal">&times;</button>
                        <h4 class="modal-title">Please insert data!</h4>
                    </div>
                    <div class="modal-body">
                        <form action="{{url_for('insert')}}" method="POST">
                            <div class="form-group">
                                <label>Name:</label>
                                <input type="text" class="form-control" name="name" required='1'>
                            </div>
                            <div class="form-group">
                                <label>Contact No. :</label>
                                <input type="text" class="form-control" name="contact" required='1'>
                            </div>
                            <div class="form-group">
                                <label>Email</label>
                                <input type="text" class="form-control" name="email">
                            </div>
                            <div class="form-group">
                                <label>Place</label>
                                <input type="text" class="form-control" name="place" required='1'>
                            </div>
                            <div class="form-group">
                                <button class="btn btn-primary" type="submit">Insert Data</button>
                            </div>
                        </form>
                    </div>
                    <div class="modal-footer">
                        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                    </div>
                </div>
            </div>
        </div>

不知何故，我无法让它出现在我的页面上

这是它的样子 in the website itself

但是它被插入到实际的数据库中 Didnt paste the entire picture because there are some personal details

表名是oxygen，我可能认为它对名称本身做了一些事情，我就是不明白

解决方法

改变这个...

{% for row in oxygen %}
                
                    <tr>
                        <td>{{row.0}}</td>
                        <td>{{row.1}}</td>
                        <td>{{row.2}}</td>
                        <td>{{row.3}}</td>
                        <td>{{row.4}}</td>
                        <td>
                            <a href="" class="btn btn-warning btn-xs" data-toggle="modal" data-target="#modaledit">Edit</a>
                            <a href="" class="btn btn-danger btn-xs" onclick="return confirm('Are you sure you want to delete?')">Delete</a>


                        </td>
                    </tr>
                {% endfor %}

到

{% for row in oxygen %}
                
                    <tr>
                        <td>{{row["id"]}}</td>
                        <td>{{row["name"]}}</td>
                        <td>{{row["contact"]}}</td>
                        <td>{{row["email"]}}</td>
                        <td>{{row["place"]}}</td>
                        <td>
                            <a href="" class="btn btn-warning btn-xs" data-toggle="modal" data-target="#modaledit">Edit</a>
                            <a href="" class="btn btn-danger btn-xs" onclick="return confirm('Are you sure you want to delete?')">Delete</a>


                        </td>
                    </tr>
                {% endfor %}
