Question

我是新手！！我有一项任务是根据从下拉菜单中选择的选项填充字段值。

Forms.py

from django import forms
from .models import MainPage
import datetime
from datetime import date

techlist = (
    ('DateOfDrive', 'DateOfDrive'),
    ('NameOfDrive', 'NameOfDrive'),
    ('Status', 'Status'),
    ('Marks_Scored', 'Marks_Scored'),
    ('First_Round_Interviewer_Name', 'First_Round_Interviewer_Name'),
    ('Second_Round_Interviewer_Name', 'Second_Round_Interviewer_Name'),
    ('Third_Round_Interviewer_Name', 'Third_Round_Interviewer_Name'),
    ('Management_Round_Interviewer_Name', 'Management_Round_Interviewer_Name'),
    ('HR_Round_Interviewer_Name', 'HR_Round_Interviewer_Name')
)


class analysisForm(forms.Form):

    GroupBy = forms.ChoiceField(choices=techlist)
    where = forms.CharField()
    datefrom = forms.DateField(initial="2019-01-01")
    dateto = forms.DateField(initial=date.today())

views.py

class analysis(FormView):
    template_name = 'analysis.html'
# View for the analysis page

    def get(self, request):
        form = analysisForm()
        return render(request, self.template_name, {'form': form})

    def post(self, request):
        form = analysisForm(request.POST)
        if form.is_valid():
            groupbyf = form.cleaned_data['GroupBy']     # Getting the groupby otpion from the user
            wheref = form.cleaned_data['where']  # Getting the search element from the user
            datetof = form.cleaned_data['dateto']       # Getting the end date from the user
            datefromf = form.cleaned_data['datefrom']   # Getting the from date from the user

            # Loading the excel to data frame
            query = str(Summary.objects.all().query)
            df_view_summary = pd.read_sql_query(query, connection)
            print(df_view_summary)

            # Extracting the month number from the complete date
            df_view_summary['Month'] = pd.DatetimeIndex(df_view_summary['DateOfDrive']).month

analysis.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

    <form action=""  method="post">

        {% csrf_token %}

        <table>
            {{ form.as_p }}
        </table>

          <input type="submit">
        </form>
            # Loading the excel to data frame
            query = str(Summary.objects.all().query)
            df_view_summary = pd.read_sql_query(query, connection)
            print(df_view_summary)

            # Extracting the month number from the complete date
            df_view_summary['Month'] = pd.DatetimeIndex(df_view_summary['DateOfDrive']).month

</body>
</html>

我现在应该根据从表单中下拉groupby字段中选择的值，在django中填充where字段，我该怎么做。在下拉列表中选择一个值后，立即在where字段中填充将由视图发送的值。如何在没有Ajax / Javascript的情况下执行此操作。

根据从Django表单的下拉列表中选择的值显示字段值
