Re: and keyword arguments '{u'student_id': None, u'school_id': 1}' not found.
I found it. Inside {%%} shoud use variable. Inthis case is
form.instance.id instead of {{form.instance.id}}

Re: and keyword arguments '{u'student_id': None, u'school_id': 1}' not found.
If I pass in a variable to the template like
return render_to_response("grading_school_form.html",
RequestContext(request, { "formset": formset, "pk":school_id, "spk":1}))
then in the template
{% for form in formset %}
{{ spk }}
{{ form.first_name }}
{{ form.last_name}}
{{ form.schoolName }}
Enter Student Score
{% endfor %}
It does work.
But i need to dynamicly assign the form ID to the student id like
student_id= form.instanse.pk
then it complain
like
everse for 'gradingstudent' with arguments '()' and keyword arguments
'{u'student_id': None, u'school_id': 1}' not found.
when i try to assign spk = form.instanse.pk
like
{% with form.instance.id.to_int as spk%}
{{ spk }}
{{ form.first_name }}
{{ form.last_name}}
{{ form.schoolName }}
Enter Student Score
{% endwith %}

Formset from inlineformset_factory for the model who has multiple foreign key?
I got this Error when I hit the submit from
'ManagementForm data is missing or has been tampered with']
class Course(models.Model):
course = models.CharField(max_length=30)
course_name = models.CharField(max_length=30)
class Student(models.Model):
first_name = models.CharField(max_length=30)
last_name = models.CharField(max_length=30)
grade = models.CharField(max_length=2,
choices=YEAR_IN_SCHOOL_CHOICES
class ContestScore(models.Model):
student = models.ForeignKey(Student)
course = models.ForeignKey(Course)
score = models.FloatField()
def __unicode__(self):
return u"%s - %s - %s" % (self.student, self.course, self.score)
In the view
def grading_student(request, school_id=1, student_id=1):
student = Student.objects.get(pk=student_id)
ContestInlineFormSet = inlineformset_factory(Student, Score, extra =0)
if request.method == "POST":
formset = ContestInlineFormSet(request.POST, instance=student)
# Do something. Should generally end with a redirect. For
example:
return HttpResponseRedirect(reverse ('contest:gradings',
args=(school_id),))
else:
formset = ContestInlineFormSet(instance=student)
return render_to_response("grading_student_form.html",
RequestContext(request, { "formset": formset}))
the formset = ContestInlineFormSet(instance=student) render the page good.
But when I click submit to post data
the formset = ContestInlineFormSet(request.POST, instance=student) give me
the error
ManagementForm data is missing or has been tampered with']
Please help! What I am doing wrong here?
If the model has only one foreign key it work fine.
Thanks.
