How to set image field as optional? - django

Question

How to set image field as optional? I am trying to set image field as optional(None or selected). Image field is None its throwing "MultiValueDictKeyError" when submit the form. I want to make this image field as None.
models.py
class Profile(models.Model):
first_name = models.CharField(max_length=255, blank=True, null=True)
last_name = models.CharField(max_length=255, blank=True, null=True)
image = models.ImageField(upload_to='images', blank=True, null=True)
forms.py
class Meta:
model = Profile
fields = '__all__'
views.py
def profile(request):
if request.method == 'POST':
form = ProfileForm(request.POST)
if form.is_valid:
first_name = request.POST.get('first_name')
last_name = request.POST.get('last_name')
image = request.FILES['images']
file_storage = FileSystemStorage()
obj = Profile(first_name=first_name, last_name=last_name, image=file_storage.save(image.name, image))
return render(request, 'index.html',{})
return render(request, 'index.html',{})
return render(request, 'index.html',{})
index.html
<form action="#" method="post" enctype="multipart/form-data">
{% csrf_token %}
<input type="text" name="first_name" class="form-control form-control" id="fname">
<input type="text" name="last_name" class="form-control form-control" id="lname">
<input type="file" name="images" class="form-control" id="image">
<button type="submit" class="btn btn-primary mt-5 mb-5">Save</button>
</form>

use the same method you're using in the other fields:
image = request.FILES.get('images')
this will make image = None if it doesn't exist in the request. then:
image_saved = None
if image is not None:
image_saved = FileSystemStorage().save(image.name, image)
obj = Profile(first_name=first_name, last_name=last_name, image=image_saved)
