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 %}
<tr>
<td>{{ spk }}</td>
<td>{{ form.first_name }}</td>
<td>{{ form.last_name}}</td>
<td>{{ form.schoolName }}</td>
<td><a href="{% url 'contest:gradingstudent' school_id=pk
student_id=spk %}"> Enter Student Score </a></td><tr>
{% 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%}
<tr>
<td>{{ spk }}</td>
<td>{{ form.first_name }}</td>
<td>{{ form.last_name}}</td>
<td>{{ form.schoolName }}</td>
<td><a href="{% url 'contest:gradingstudent' school_id=pk
student_id=form.instance.id %}"> Enter Student Score </a></td><tr>
{% endwith %}
