Django ChoiceField saves None value after editing?

I have a Model as follows,

gender = (
    ('Male', 'Male'),
    ('Female', 'Female'),
    )

class UserProfile(models.Model):
    profile_id = models.CharField(max_length=60, blank=True,default='',)
    gender = models.CharField(max_length=60, blank=True, default='',
                              choices=gender,verbose_name="gender")

I have a modelform as follows for that model,

 class UserProfileForm(forms.ModelForm):

def __init__(self, *args, **kargs):
    super(UserProfileForm, self).__init__(*args, **kargs)
   class Meta:
       model = UserProfile
       fields = '__all__'

And views for editing form,

  def userprofile_edit(request, pk):
       userprofile = UserProfile.objects.get(pk=pk)
       form = UserProfileForm(request.POST or None,instance=userprofile)

       if request.method == "POST":
          form = UserProfileForm(request.POST or None,instance=userprofile)
         if form.is_valid():
            post = form.save(commit=False)
            post.save()
            return redirect('userprofile')
         else:
           form = UserProfileForm(instance=userprofile)
      else:
          form = UserProfileForm(request.POST or None,instance=userprofile)
      return render(request,'userprofiles/user_edit.html', {'form':form,'userprofile': userprofile})

And Template for Edit userprofile form,

    <div class="col-md-3">
       <div class="form-group">
             <label>Gender <star>*</star></label>
             <select name="gender" required class="selectpicker" value="{{ userprofile.gender }}"  data-title="{{ userprofile.gender }}" data-style="btn-default btn-block" data-menu-style="dropdown-blue">
{% for Male,Female in form.fields.gender.choices %}
   <option value="{{ Male }}"{% if form.fields.gender.value == Male %} selected{% endif %}>{{ Female }}</option>
{% endfor %}
</select>

The Problem is only while editing the userprofile form,when I click the submit button for this form, it raises "This field is required". When I click the choicefield and select an option, it works. But if I didn't select an option it saves a None.I wanted to know how to pass values to selectfield. Please help?

You have declare gender default as "" empty string. So in your form just put the empty string if user doesn't select any...

<option selected="selected" value=""></option>

Since you are using a model form, there is no need to write an HTML for the form, anyways you are returning the form from the view.You can write it as:

<div>
 <form action="your url" method="POST">
 {% csrf_token %}
  {{ form.as_p }}
<butoon type="submit">Update</button>
</form>

The only possibility the choice field is coming as blank, is that it might not be selected.
