{% for core in corevalues %}
<td colspan="8"><input type="hidden" value="{{core.id}}" name="core">{{core.Description}}</td>
{% endfor %}

{% for corevalues in corevaluesperiod %}
<td colspan="4" style="font-size: 12px"><input type="hidden" value="{{corevalues.id}}" name="coredescription">{{corevalues.Description}}</td>
{% endfor %}

</table>
<input type="submit" value="Insert" id="submit">
</form>
this is what its looks like in web view
this is my code in my views where the data inserted
def studentbehavior(request):
id = request.POST.get('teacher')
teacher = EmployeeUser(id=id)
coreid = request.POST.get('core')
core = CoreValues(id=coreid)
corevalues = []
for corevaluesid in request.POST.getlist('coredescription'):
corevalues.append(corevaluesid)
coreperiodID = request.POST.get('coreperiod')
coreperiod = gradingPeriod(id = coreperiodID)
marking = []
for markingID in request.POST.getlist('marking'):
marking.append(markingID)
print(marking.append(markingID))
for m in request.POST.getlist('marking'):
for student in request.POST.getlist('student'):
students = StudentPeriodSummary(id=student)
#s = marking[m]
for desc in request.POST.getlist('coredescription'):
coredescription = CoreValuesDescription(id=desc)
V_insert_data = StudentsCoreValuesDescription(
Teacher=teacher,
Core_Values=coredescription,
Marking=m,
Students_Enrollment_Records=students,
grading_Period=coreperiod,
)
V_insert_data.save()
return render(request, "Homepage/updatebehavior.html")
this my problem, all markings saved to the datavase even if I select only one in the selection box, (in admin view), looks like the data entering in the database is incorrect.
this is my desire answer
UPDATE
WHEN I try the answer of mr#Saisiva A
for m, student, desc in zip(request.POST.getlist('marking'), request.POST.getlist('student'),
request.POST.getlist('coredescription')):
coredescription = CoreValuesDescription(id=desc)
students = StudentPeriodSummary(id=student)
V_insert_data = StudentsCoreValuesDescription(
Teacher=teacher,
Core_Values=coredescription,
Marking=m,
Students_Enrollment_Records=students,
grading_Period=coreperiod,
)
V_insert_data.save()
this is the data i inputted
this is the result i received in my admin site
Update
I am selecting a mark for every student and every core value then sending all data back to the server
If i want to input like this
the result inserted in my database is like this
UPDATE AGAIN when i try to add this to my views
for markingID in request.POST.getlist('marking'):
marking.append(markingID)
print(marking[m])
the error says
list indices must be integers or slices, not str

Answer 1

try this
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,
# Education_Levels
Students_Enrollment_Records=students,
Grading_Period=coreperiod,
Grading_Behavior=cores,
Marking=s,
)
V_insert_data.save()

Answer 2

Just modify the code in below format
for m, students, desc in zip(request.Post.getlist('marking'), request.Post.getlist('student'), request.Post.getlist('coredescription')):
V_insert_data = StudentsCoreValuesDescription(
Teacher=teacher,
Core_Values=coredescription,
Marking=m,
Students_Enrollment_Records=students,
grading_Period=coreperiod,
)
V_insert_data.save()
return render(request, "Homepage/updatebehavior.html")
