python - Django : Maintaining option selected in HTML template

Question

当我在 html 模板中使用 django if 函数来设置对所选选项标签的更改时，但它一直选择 --SELECT-- 选项

 <form  method="post">

<select name="name">
<option >--SELECT--</option>
  {% for job in all_pekerjaan%}
  <option value="{{job.id}}"
         {% if job.id == current_name %}selected="selected"{% endif %}>
         {{job.name}}
     </option>
    {% endfor %}
</select>
{% csrf_token %}

  <input type="submit" class="btn btn-success" value="submit" >
</form>

这是我的views.py

from django.http import HttpResponse
from .models import daftartabel, Pekerjaan
from .forms import form1, form2
from django.template import loader
from django.shortcuts import render

def index(request):

    if request.method == 'POST':
        #print(request.POST['name'])
        current_name=request.POST['name']
        all_datas = daftartabel.objects.filter(pekerjaan_id=request.POST['name'])
    else:
        all_datas = daftartabel.objects.all()
    all_pekerjaan = Pekerjaan.objects.all()
    template = loader.get_template('tabel/index.html')
    #print(all_datas)
    #print(all_pekerjaan)
    context = {
        'all_datas' : all_datas,
        'all_pekerjaan' : all_pekerjaan,
        'current_name' : request.POST['name'],
    }
    #print (context)
    print(type(context['current_name']))

    return HttpResponse(template.render(context, request))

我的forms.py 类

class form2(forms.Form):
    name = forms.CharField(max_length=100)

有人知道如何解决这个问题吗？

问题已解决，将“current_name”更改为整数会有所帮助。

if request.method == 'POST':
        context = {
            'all_datas' : all_datas,
            'all_pekerjaan' : all_pekerjaan,
            'current_name' : int(request.POST['name']),
            }
    else:
                context = {
                    'all_datas' : all_datas,
                    'all_pekerjaan' : all_pekerjaan,
                    }
