Tell me how to transfer this code from Html to models - django

Question

There is a code in html {{post.author.posts.count}} that counts the number of posts by the author.
I have such a question, how to transfer it to views.py
def post_detail(request, post_id):
post = get_object_or_404(Post, id=post_id)
context = {
'post': post,
}
return render(request, 'posts/post_detail.html', context)
class model
class Post(models.Model):
text = models.TextField(verbose_name='Текст')
pub_date = models.DateTimeField(
auto_now_add=True,
verbose_name='Дата публикации'
)
group = models.ForeignKey(
Group,
on_delete=models.SET_NULL,
blank=True,
null=True,
related_name='posts',
verbose_name='Группа',
)
author = models.ForeignKey(
User,
on_delete=models.CASCADE,
related_name='posts',
verbose_name='Автор',
)
def __str__(self):
return self.text
I need to find an existing post, find its author and sort all posts by this author and calculate the total number of posts

Answer 1

You can not pass values form HTML to views in Django, but you can create #property to count all posts of the specific author.
you can try like this
models.py
class Post(models.Model):
text = models.TextField(verbose_name='Текст')
pub_date = models.DateTimeField(
auto_now_add=True,
verbose_name='Дата публикации'
)
group = models.ForeignKey(
Group,
on_delete=models.SET_NULL,
blank=True,
null=True,
related_name='posts',
verbose_name='Группа',
)
author = models.ForeignKey(
User,
on_delete=models.CASCADE,
related_name='posts',
verbose_name='Автор',
)
def __str__(self):
return self.text
views.py
def Demoview(request,post_id):
get_post = Post.object.get(id=post_id)
author_of_post = get_post.author
all_post_of_author= Post.object.filter(author__id=get_blog.author.id)
count_all_post_of_author= Post.object.filter(author__id=get_blog.author.id).count()
context = {
'author_of_post':author_of_post,
'all_post_of_author':all_post_of_author,
'count_all_post_of_author':count_all_post_of_author,
}
return render(request,'post.html',context)

Happened. Here is the code that came out.
def post_detail(request, post_id):
post = get_object_or_404(Post, id=post_id)
author = post.author
post_count = Post.objects.filter(author=author).count()
context = {
'author': author,
'post_count': post_count,
'post': post,
}
return render(request, 'posts/post_detail.html', context)
