如何在django中将变量的值从视图发送到表单？

from django import forms

class MyForm(forms.Form):
    my_variable = forms.CharField(label='My Variable')

from django.shortcuts import render
from .forms import MyForm

def my_view(request):
    my_variable = 'Hello, World!'
    form = MyForm(initial={'my_variable': my_variable})
    return render(request, 'my_template.html', {'form': form})

<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Submit</button>
</form>
