如何从views.py中的Django模板获取变量的值？

Question

I am working in django and want to pass the value in views.py my code is

template

     {% for doctor in doctor_list %}
       {% if citysearch == doctor.city %}
         <h1>Name of doctor is </h1>
          <form class="form" method="POST">
                  {% csrf_token %}
             <input type="submit", class="btn view", name="{{doctor.contactNumber}}" value="View Profile">
          </form>
        {% endif %}
        {% endfor %}

view

    if request.method == 'POST':
        selectdocnum = request.POST.get["doctor.contactNumber"]
        print(selectdocnum)
        return redirect('patientPannel')

This is not returning the value of doctor.contactNumber, and error is method object is not subscriptable

Answer 1

doctor.contactNumber is a value , not a key that you should be using to lookup a value or as a name for a input field. give the input field a better name and use that instead. You're also using the wrong input type, either use hidden if you don't expect it to be edited, or something like text if it can be.

<input type="hidden" name="contactNumber" value="{{doctor.contactNumber}}">

request.POST.get("contactNumber")

Answer 2

this is wrong,

<input type="submit", class="btn view", name="{{doctor.contactNumber}}" value="View Profile">

i think you have to do this

 {% for doctor in doctor_list %}
   {% if citysearch == doctor.city %}
     <h1>Name of doctor is </h1>
      <form class="form" method="POST">
              {% csrf_token %}
         <input type="text" value="{{doctor.contactNumber}}" name="doctorcontactnumber">
         <input type="submit" class="btn view" value="View Profile">
      </form>
    {% endif %}
    {% endfor %}

your views

    if request.method == 'POST':
    selectdocnum = request.POST.get["doctorcontactnumber"]
    print(selectdocnum)
    return redirect('patientPannel')

Answer 3

It's normal, request.POST.get is a method. Use parenthesis.The right call is:

selectdocnum = request.POST.get("doctorcontactnumber")

For your input, you have jumbled name and value . Do this instead:

<input type="hidden" name="doctorcontactnumber" value="{{doctor.contactNumber}}">

Answer 4

<input type="submit", class="btn view", name="number" value="{{doctor.contactNumber}}">
if request.method == 'POST':
    selectdocnum = request.POST.get("number")
    print(selectdocnum)
    return redirect('patientPannel')

in place of value you have to use the {{doctor.contactNumber}} and you have to get the data using the name(request.POST.get("number")) then it will get the data
