尝试查看其他解决方案,但我无法解决此问题。我有一个问题,即django模板将遍历{% for cr in Courses %}
,但只有在一起输出多行时才会这样做。例如。给定一个列表[['3000', '1', '2458'], ['3000', '0', '2821']]
,一个迭代将是整个列表,而不是列表中的两个项目。
在我的django模板中,我有:
<table>
<tr><th>Course</th><th>Payment Status</th><th>Unit</th><th>Action</th></tr>
{% for course in Comp_Course %}
<tr><td>{{ course }}</td><td></td><td></td><td></td></tr>
{% for cr in Courses %}
{% if course == cr.0 %}
<tr>
<td></td>
<td>
{% if cr.1 == "1" %}
Paid
{% else %}
Not Paid
{% endif %}
</td>
<td>
{{ cr.2 }}
</td>
<td>
</td>
</tr>
{% endif %}
{% endfor %}
{% endfor %}
</table>
在我的views.py
中 courses = []
comp_course = []
for payment in transactions:
if payment.payment_type == "1":
unit = Units.objects.get(webducate_id=str(payment.course))
comp_course.append(str(unit.course.webducate_id))
units = Units.objects.filter(course=unit.course)
unit_list = []
for unit in units:
if unit.webducate_id == payment.course and payment.successfull == "1":
unit_list.append([str(unit.course.webducate_id),'1',str(unit.webducate_id)])
else:
unit_list.append([str(unit.course.webducate_id),'0',str(unit.webducate_id)])
courses.append(unit_list)
comp_course = list(set(comp_course))
return render_to_response('student-account.html', {'Courses': courses, 'Comp_Course': comp_course,'Message': "", 'Transactions': transactions}, context_instance=RequestContext(request))
我想我在某个地方有一个小问题,但我正在努力。感谢

IMO课程如下:
[[[a,b,c],[d,e,f]]]
试试这个
courses = []
comp_course = []
for payment in transactions:
if payment.payment_type == "1":
unit = Units.objects.get(webducate_id=str(payment.course))
comp_course.append(str(unit.course.webducate_id))
units = Units.objects.filter(course=unit.course)
unit_list = []
for unit in units:
if unit.webducate_id == payment.course and payment.successfull == "1":
courses.append([str(unit.course.webducate_id),'1',str(unit.webducate_id)])
else:
courses.append([str(unit.course.webducate_id),'0',str(unit.webducate_id)])
comp_course = list(set(comp_course))
return render_to_response('student-account.html', {'Courses': courses, 'Comp_Course': comp_course,'Message': "", 'Transactions': transactions}, context_instance=RequestContext(request))
