Question

我已经为学生的markdata输入开发了一个Django项目。不幸的是，条目应针对每个主题和每个问题。每个主题中的问题数量都不同。为了方便进行数据输入，我计划在提交时在html表中放置多个文本框，这些多个文本框的值应该用逗号连接并存储在数据库的单个字段中。

我提供了以下视图，模型和模板代码：

views.py：

def savemark(request):
    if request.POST:
        subject=request.POST.get("subject")
        subdata = Subject.objects.filter(subid=subject)
        course=request.POST.get("course")
        year=request.POST.get("year")
        cohart=request.POST.get("cohart")
        exam=request.POST.get("exam")
        examdata = Exam.objects.filter(examid=exam)
        qddata=Questiondetails.objects.filter(subid=subject,examtype=exam)
        studata=Studentcohart.objects.filter(cohartid=cohart,currentyear=year).values('studentid')
      return render(request,'blog/savemarks.html',{'student':studata,'question':qddata,'subject': subdata,'exam':examdata,'course':course,'year':year,'cohart':cohart})
    else:
        return render(request,'blog/home.html')

models.py

    class Mark(models.Model):
        year = models.CharField(max_length=20)
        mark = models.IntegerField()
        subid = models.ForeignKey('Subject', models.DO_NOTHING, db_column='subID')  # Field name made lowercase.
        studentid = models.ForeignKey('Student', models.DO_NOTHING, db_column='studentID')  # Field name made lowercase.
        examid = models.ForeignKey(Exam, models.DO_NOTHING, db_column='examID')  # Field name made lowercase.

    class Meta:
        managed = False
        db_table = 'Questiondetails'

    def __str__(self):
       return u'%s %s %s %s %s %s %s %s %s %s' % (self.id,self.cohartid,self.year,self.examtype,self.courseid,self.subid,self.totalnoofquestions,self.MCQ,self.SBA,self.SA)

        db_table = 'exam'
    def __str__(self):
       return u'%s %s %s' % (self.examid,self.examname,self.type)

savemarks.html

<html>
<body>
<table>
<form action="/submit/" method="post" >
    <tr>
        <th>studentid</th>
{% for i in "x"|rjust:"30" %}
<th>Q{{forloop.counter}}</th>
{% endfor %}
</th>q{{forloop.counter}}<th> 
    </tr>
{% for sub in student%}
<tr> 
<td>
    {{ sub.studentid}}
</td>
{% for i in "x"|rjust:"30" %}
<td> 
<input type="text" name="mark" /><br />
</td>
{% endfor %}
</tr>
{% endfor %}
<table>
<input type="submit" value="Log In"/> 
</form>

<p><a href="{% url 'logout' %}">Log out</a></p>

</body>
</html>

我不知道如何实现将字段拆分为多个文本框并将数据收集回db。请有人指导我如何实现这一目标。预先感谢

Django：将来自多个文本框的输入组合到单个字段中
