Django TextField is always required despite empty = True, Null = True

I'm having problems with a field that seems to always be required, despite my best wishes. The text field "word_search" always asks for input, but I tried to make sure that the parameters allow a space.

my model is as follows. You can see empty = True, options Null = True

class IAV(models.Model):

  z_score = models.DecimalField(max_digits = 4,decimal_places=4)
  screens = models.IntegerField(default=0)
  flu_proteins = models.IntegerField(default = 0)
  Key_word = models.TextField(blank=True,null=True)
  sess = models.ForeignKey(Sess_IAV,default=None)

My opinion is this:

def new_IAV(request):

  if request.method == "POST":
    form = IAVForm(request.POST,request.FILES)
    if form.is_valid():
      sess_ = Sess_IAV.objects.create()
      form.save(
          for_page=sess_,
          z_score = form.cleaned_data("z_score"),
          screens = form.cleaned_data("screens"),
          flu_proteins = form.cleaned_data("flu_proteins"),
          Key_word = form.cleaned_data("key_word"),
          )
      return redirect(sess_)
    else:
      print(form.errors)
  else:
    url=reverse('IAV_home')
    return HttpResponseRedirect(url)

My form is as follows. you can see the required attribute = False.

class IAVForm(forms.models.ModelForm):

  z_score = forms.DecimalField(widget=forms.NumberInput(attrs={'class':'form-control','value':'0.0',}))

  screens = forms.IntegerField(widget=forms.NumberInput(attrs={'class':'form-control','value':'0',}))

  flu_proteins = forms.IntegerField(widget=forms.NumberInput(attrs={'class':'form-control','value':'0',}))

  key_word = forms.CharField(widget=forms.Textarea(attrs={'class':'form-control','rows':1,'cols':10,'placeholder':'keword values','required':'False'}))


  class Meta:
    model=IAV
    fields=('z_score','screens','flu_proteins','key_word')

  def save(self,for_page,z_score,screens,flu_proteins,key_word):
    self.instance.sess = for_page
    self.instance.z_score = z_score
    self.instance.screens = screens
    self.instance.flu_proteins = flu_proteins
    self.instance.key_word = key_word
    return super().save()

I'm not sure how this field cannot be empty, given that the model has options "blank = True, null = True".

The widget also says that it is not required.

This is what shows up
