before applying json method I was using this {{filt.body|striptags|safe|slice:":250" }} in my html template for escape all special character. Now my data loading from json and how to apply above method in my html template.

models.py

class Blog(models.Model):
       body = RichTextUploadingField()

views.py

class PostJsonListView(View):
    def get(self, *args, **kwargs):

        posts = list(Blog.objects.all().filter(is_published='published') )
        data = list()
        for i in posts:
            data.append({'body':i.body})
            
          
       
        return JsonResponse({'data':data},safe=False)

CodePudding user response：

You can do it in your view like this:

from django.utils.safestring import SafeString
from django.utils.html import strip_tags

for i in posts:
   body = strip_tags(SafeString(i.body))[:250]
   data.append({'body':  body})
