How to Increment IntegerField on django on button click from template?

How to Increment IntegerField on django on button click from template? I have two buttons on template one for like and other for dislike.I am using different post requests for both of them but get no increase on likes and dislikes. I hope Information is complete.

Here is the models.py code

    class Post(models.Model):
        Title=models.CharField(max_length=50)
        slug = models.SlugField(unique=True,null=True,blank=True)
        Meta_Tags = models.CharField(max_length=200,null=True)
        Description=models.TextField()
        Category=models.CharField(max_length=50)
        Body=RichTextUploadingField()
        Date=models.DateField(auto_now_add=True)   
        Views=models.IntegerField(default=0,null=True)
        Likes=models.IntegerField(default=0,null=True)
        Dis_Likes=models.IntegerField(default=0,null=True)

        def __str__(self):
            return self.Title + " | " + str(self.Date)

here is the view.py code

    def blogdetail(request,slug):
        post=Post.objects.get(slug=slug)
        post.Views +=1
        if request.POST.get('Like'):
            post.Likes +=1
        if request.POST.get('DisLike'):
            post.Dis_Likes +=1   
        post.save()
        context={
            'post':post
        }
        return render(request,'blogdetail.html',context)

template code is here

            <div class="submit-reaction p-3 mb-5">
            <span class="p-x3 mb-5" style="float:left">
            <form action="" method="post">
            {% csrf_token %}
            <button  type="submit" name="Like"style="border:none;background:none;"><i 
            class="far fa-3x fa-thumbs-up text-secondary"></i></button>
            </form>
            </span>
            <span class="p-x3 mb-5" style="float:right">
            <form action="" method="post">
            {% csrf_token %}
            <button type="submit" name="DisLike"style="border:none;background:none;"> 
           <i class="far fa-3x fa-thumbs-down text-secondary"></i></button>
            </form>
            </span>
            </div>

Use an F() expression for it

from django.db.models import F

reporter = Reporters.objects.get(name='Tintin')
reporter.stories_filed = F('stories_filed') + 1
reporter.save()

See:

https://docs.djangoproject.com/en/3.2/ref/models/expressions/#f-expressions

The Like in your template is through form submit button not from form input value

So change like this.

if 'Like' in request.POST:
    post.Likes +=1
    post.save()
