Django HttpResponseRedirect either crashes the site or shows a blank page-CodePudding

I have this issues with Django forms where on each refresh the form would resubmit the last input into the database I tried working with "HttpResponseRedirect" but it would either crash the site or show a blank page.

Heres the code of views.py:

def page(request) : 
    employe = Employe.objects.all()
    if request.method =='POST' :
      form = EmployeForm(request.POST)
      if form.is_valid():
         form.save()
         return HttpResponseRedirect("")
    else :
      form = EmployeForm()
    return render(request,'hello.html',{'employe':employe,'form':form,})

Form template:

              <form method="POST">
                {% csrf_token %}
                {{ form }}
                <button type="submit" >Ajouter</button>
              </form>

Forms.py:

from django import forms 
from .models import Employe

class EmployeForm(forms.ModelForm):
    class Meta:
        model = Employe
        fields = '__all__'

CodePudding user response：

You should provide some success url inside HttpResponseRedirect as:

return HttpResponseRedirect("/success/")

Or you can call the name of view as:

return HttpResponseRedirect(reverse("some_path_name"))

To redirect on the same page use:

return HttpResponseRedirect(request.path_info)
