django print循环值只有一次 [英] django print loop value only once

问题描述

  def HospitalAppointmentView（request，pk，用户名，hdpk）：
 todays_appointments = DoctorAppointment.objects.filter（hospital__id = pk，doctor__id = hdpk，appointment_date = today）.order_by（ - 约定日期）[：5] 
 
返回render_to_response（'doctor_appointment_list.html'，{todays_appointments：todays_appointments}，context_instance = RequestContext（request））
  

在我的模板中：

  {％todays_appointments％} 
< h3> {{约会。 doctor.username}}< H3> 
< tr> 
< td> {{约会/任务日期}}< / td> 
< td> {{约会最初的名字}}& nbsp; {{约会的中间名}}& nbsp; {{appointment.last_name}}< / TD> 
< td> {{约会用户}}< / td>< / tr> 
< a href ={％urlall_appointmentsappointment.hospital.id appointment.doctor.id％}> 
查看全部< / a> 
 
 {％endfor％} 
  

它显示正确的5个约会，查看全部重复5次，我想以医生的用户名作为标题，并将其打印5次。

当我点击查看全部我想重定向到可以看到所有约会的页面。喜欢：

  def HospitalAppointmentView（request，pk，username，hdpk）：
 todays_appointments = DoctorAppointment.objects.filter $ _ 
 $ b返回render_to_response（'all_appointment.html'，{todays_appointments：todays_appointments}，context_instance = RequestContext（请求（request_id = pk，doctor__id = hdpk，约会日期=今天） ））
  

如果我在for循环之外写See All，我无法访问hospital.id doctor.id和里面的循环我得到查看全部5次，同样的{{约会.doctor.username}}。

如果不打印5次，并且打印一次{{约会.doctor.username}}所需的所有信息，我如何重定向？

解决方案

您可以使用 {{forloop.first}} 第一次迭代
喜欢...

  {％在约会在todays_appointments％} 
 
 {％如果forloop.first％} 
< h3> {{约会.doctor.username}}< h3> 
 {％endif％} 
 
 ... 
 {％endfor％} 
  

I have a view where I am getting the list of appointments with limit..

def HospitalAppointmentView(request, pk, username, hdpk):
todays_appointments = DoctorAppointment.objects.filter(hospital__id=pk, doctor__id=hdpk, appointment_date=today).order_by("-appointment_date")[:5]

return render_to_response('doctor_appointment_list.html', {"todays_appointments": todays_appointments}, context_instance=RequestContext(request))

In my template:

{% for appointment in todays_appointments %}
    <h3>{{appointment.doctor.username}}<h3>
    <tr>
    <td>{{appointment.appointment_date}}</td>
    <td>{{appointment.first_name}} &nbsp;{{appointment.middle_name}} &nbsp; {{appointment.last_name}}</td>
    <td>{{appointment.user}}</td></tr>
    <a href="{% url "all_appointments" appointment.hospital.id appointment.doctor.id%}">
    See All</a>

{% endfor %}

Its showing the 5 appointments correctly except "See All" is repeated 5 times and I want to make doctor's username as title and its also being printed 5 times.

When I click "See All" I want to redirect to the page where all appointments can be seen. Like:

def HospitalAppointmentView(request, pk, username, hdpk):
todays_appointments = DoctorAppointment.objects.filter(hospital__id=pk, doctor__id=hdpk, appointment_date=today).order_by("-appointment_date")

return render_to_response('all_appointment.html', {"todays_appointments": todays_appointments}, context_instance=RequestContext(request))

If I write "See All" outside the for loop I cant access the hospital.id and doctor.id and inside the loop I m getting "See All " 5 times and same goes with {{appointment.doctor.username}}.

How can I redirect without being printed 5 times with all information needed in the url and {{appointment.doctor.username}} being printed once?

解决方案

You can use {{forloop.first}} for, it will be true for 1st iteration. Like ...

{% for appointment in todays_appointments %}

    {% if forloop.first %}
        <h3>{{appointment.doctor.username}}<h3>
    {%endif%}

    ...
{%endfor%}
