Hi all.
Cannot resolve keyword 'published_date_lte' into field. Choices are: author,
author_id, comments, create_date, id, published_date, text, title
this are models:
from django.db import models
from django.utils import timezone
from django.urls import reverse
# Create your models here.
class Post(models.Model):
author = models.ForeignKey('auth.User', on_delete=models.CASCADE,)
title = models.CharField(max_length=200)
text = models.TextField()
create_date = models.DateTimeField(default=timezone.now())
published_date = models.DateTimeField(blank=True, null=True)
def publish(self):
self.published_date = timezone.now()
self.save()
#def approve_comments(self):
#return self.comments.filter(approved_comments=True)
def approved_comments(self):
return self.comments.filter(approved_comment=True)
#def get_absolute_url(self):
#return reverse("post_detail", kwargs={"pk": self.pk})
def __str__self():
return self.title
class Comment(models.Model):
post = models.ForeignKey('blog.post',related_name='comments'
, on_delete=models.CASCADE,)
title = models.CharField(max_length=200)
text = models.TextField()
create_date = models.DateTimeField(default=timezone.now())
published_date = models.DateTimeField(blank=True, null=True)
approved_comment = models.BooleanField(default=False)
def approve(self):
self.approved_comment = True
self.save()
def get_absolute_url(self):
return reverse('post_list')
def __str__(self):
return self.text
And views:

# Create your views here.
class Aboutview(TemplateView):
template_name = 'about.html'
class PostListView(ListView):
model = Post
def get_queryset(self):
return
Post.objects.filter(published_date_lte=timezone.now()).order_by(
'-published_date')

redirect_field_name = 'blog/post_list.html'
model = Post
def get__queryset(self):
return Post.objects.filter(published_date_isnull=True).order_by(
