Python 如何插入每个学生的正确值，为每个核心值选择每个分数

我有一个相关的问题。我只是不知道如何获得正确的数据

就像这张照片一样 （对于每个学生，为每个corevalues选择每个分数（是展示自豪感…））：

这是my views.py：

for i, mark in enumerate(request.POST.getlist('Marking')):
    p = marking[int(mark)]
    s = StudentBehaviorMarking(id=p)
    core = corevalues[i]
    cores = EducationLevelGradingBehavior(id=core)
    print(s, cores)
    for student in  request.POST.getlist('student'):
        students = StudentPeriodSummary(id=student)
        V_insert_data = StudentsBehaviorGrades(
                Teacher=teacher,
                #Education_Levels
                Students_Enrollment_Records = students,
                Grading_Period = coreperiod,
                Grading_Behavior = cores,
                Marking = s,

            )
        V_insert_data.save()

和我的HTML：

{BehaviorPerLevel%中的corevalues为%0}
{{corevalues.Grading_Behavior.GroupName}
{%endfor%}
学名
{BehaviorPerLevel%中的corevalues为%0}
Q{{corevalues.Grading_Period.id}
{%endfor%}
{学生百分比中的学生百分比}
{{学生.学生注册记录.学生注册记录.学生注册记录.学生注册记录.学生用户}
{BehaviorPerLevel%中的corevalues为%0}
{%用于行为%]中的行为
{{行为.标记}
{%endfor%}
{%endfor%}
{%endfor%}

这是my models.py：

class GradingBehavior(models.Model):
    Display_Sequence = models.IntegerField(null=True, blank=True)
    Name = models.CharField(max_length=500, null=True, blank=True)
    Description = models.CharField(max_length=500, null=True, blank=True)
    GroupName = models.CharField(max_length=500, null=True, blank=True)
    GroupDescription = models.CharField(max_length=500, null=True, blank=True)

//this is models corevalues
class EducationLevelGradingBehavior(models.Model):
    Display_Sequence = models.IntegerField(null=True, blank=True)
    GradeLevel = models.ForeignKey(EducationLevel, on_delete=models.CASCADE,
                                   null=True, blank=True)
    Grading_Behavior = models.ForeignKey(GradingBehavior, on_delete=models.CASCADE, null=True, blank=True)
    Grading_Period = models.ForeignKey(gradingPeriod, on_delete=models.CASCADE, null=True, blank=True)

//this is the models where the user selecting the marks for every core values
class StudentBehaviorMarking(models.Model):
    Marking = models.CharField(max_length=500, null=True, blank=True)
    Non_numerical_Rating = models.CharField(max_length=500, null=True, blank=True)

//this is the model where the data saves
class StudentsBehaviorGrades(models.Model):
    Teacher = models.ForeignKey(EmployeeUser, on_delete=models.CASCADE,
                                null=True, blank=True)
    Education_Levels = models.ForeignKey(EducationLevel, on_delete=models.CASCADE, null=True, blank=True)
    Students_Enrollment_Records = models.ForeignKey(StudentPeriodSummary, 
                                                    on_delete=models.CASCADE, null=True)
    Grading_Period = models.ForeignKey(gradingPeriod, on_delete=models.CASCADE, null=True, blank=True)
    Grading_Behavior = models.ForeignKey(EducationLevelGradingBehavior, on_delete=models.CASCADE, null=True, blank=True)
    Marking = models.ForeignKey(StudentBehaviorMarking,
                                on_delete=models.CASCADE, null=True)

当我尝试插入数据时

结果是：

---

如您所见，我插入的数据没有正确匹配，我没有为每个核心值获得每个学生分数的正确值

在您的视图中尝试此选项。py

marking = []
for markingID in request.POST.getlist('Marking'):
    marking.append(markingID)

for i, mark in enumerate(request.POST.getlist('Marking')):
    s = StudentBehaviorMarking(id=mark)
    core = corevalues[i]
    cores = EducationLevelGradingBehavior(id=core)
    print("mark", mark, "per description", core)
    for student in request.POST.getlist('student'):
        students = StudentPeriodSummary(id=student)
        V_insert_data = StudentsBehaviorGrades(
            Teacher=teacher,
            Students_Enrollment_Records=students,
            Grading_Period=coreperiod,
            Grading_Behavior=cores,
            Marking=s,
        )
        V_insert_data.save()

并在html中执行此操作

    {% for student in Students %}
    <tr>
        <td colspan="2"><input type="hidden" value="{{student.id}}" name="student">{{student.Students_Enrollment_Records.Students_Enrollment_Records.Students_Enrollment_Records.Student_Users}}</td>
        {% for corevalues in behaviorperlevels %}
        <td colspan="4">{{corevalues.id}}{{student.id}}
             <select name="Marking">
                 {% for behaviors in behavior %}
                 <option value="{{behaviors.id}}">{{behaviors.id}}-{{behaviors.Marking}}</option>
                 {% endfor %}
             </select>
         </td>
        {% endfor %}
    </tr>
    {% endfor %}

{%用于学生%}
{{学生.学生注册记录.学生注册记录.学生注册记录.学生注册记录.学生用户}
{BehaviorPerLevel%中的corevalues为%0}
{{corevalues.id}{{student.id}}
{%用于行为%]中的行为
{{behaviors.id}-{{behaviors.Marking}
{%endfor%}
{%endfor%}
{%endfor%}

为什么要将

核心描述

和

标记

放在列表中？填写完列表后，您就可以“按原样”使用它们。为什么不直接使用解压后的值呢<代码>标记[int（i）]-不，将值视为键不是一个好主意。这里的关键是列表中某个值的索引。先生，怎么做？请告诉我你的解决方案。你听说过Django表单和表单集吗？@Carlburbaker这和我的问题有关吗，先生？看起来使用模型表单会很有意义。也许我只是不理解你的代码
