Как исправить проблему с данными в django

Question

С начала я создал модели

class Theme(models.Model):
    theme_name = models.CharField(max_lenght = 20, unique = True)
    
class Info(models.Model):
    theme = models.ForeignKey(Theme, on_delete = models.CASCADE)
    info_theme = models.CharField(max_lenght = 20, unique = True)
    info_desc = models.TextField(default = "Leage of Leagend information")
    publish_date = models.DateTimeField(auto_now = True)

class Comment(models.Model):
    info = models.ForeignKey(Info, on_delete = models.CASCADE)
    author_name = models.CharField(max_length = 20, unique = True)
    comment_text = models.TextField(default = "comennt")
    publish_date = models.DateTimeField(auto_now = True)

Затем я почти полностью изменил models.py, сделал миграции и когда во views.py пытаюсь написать

ivent = Ivent.objects.all()oreder_by('publish_date')

И в ivents.html

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>

<p>{{ivent.ivent_theme}}</p>

</body>
</html>

Ничего не выводиться. Вот новые models.py и еще кое какие файлы которые могут пригодиться:

from django.db import models

class Theme(models.Model):
    theme_name = models.CharField(max_length = 20, unique = True)

    def __str__ (self):
        return self.theme_name

    class Meta:
        verbose_name = "Тема"
        verbose_name_plural = "Темы"

class Ivent(models.Model):
    theme = models.ForeignKey(Theme, on_delete = models.CASCADE)
    ivent_theme = models.CharField(max_length = 20, unique = True)
    ivent_info = models.TextField(default = "Leage of Leagends information")
    publish_date = models.DateTimeField(auto_now = True)

    def __str__(self):
        return self.ivent_theme

    class Meta:
        verbose_name = "Ивент"
        verbose_name_plural = "Ивенты"

class Patch(models.Model):
    theme = models.ForeignKey(Theme, on_delete = models.CASCADE)
    patch_theme = models.CharField(max_length = 20, unique = True)
    patch_info = models.TextField(default = "Leage of Leagends information")
    publish_date = models.DateTimeField(auto_now = True)

    def __str__(self):
        return self.patch_theme

    class Meta:
        verbose_name = "Патч"
        verbose_name_plural = "Патчи"

class Ivent_comment(models.Model):
    info = models.ForeignKey(Ivent, on_delete = models.CASCADE)
    author_name = models.CharField(max_length = 20, unique = True)
    comment_text = models.TextField(default = "comennt")
    publish_date = models.DateTimeField(auto_now = True)

    def __str__(self):
        return self.author_name

    class Meta:
        verbose_name = "Комментарий"
        verbose_name_plural = "Комментарии"

class Patch_comment(models.Model):
    info = models.ForeignKey(Patch, on_delete = models.CASCADE)
    author_name = models.CharField(max_length = 20, unique = True)
    comment_text = models.TextField(default = "comennt")
    publish_date = models.DateTimeField(auto_now = True)

    def __str__(self):
        return self.author_name

    class Meta:
        verbose_name = "Комментарий"
        verbose_name_plural = "Комментарии"

Если понадобятся какие-то файлы, я добавлю.

Answer 1

Во первых, правильно будет не Ivent а Event.

Во вторых, вы неправильно делаете order_by:

ivent = Ivent.objects.all()oreder_by('publish_date')

а надо:

ivent = Ivent.objects.all().order_by("publish_date")

В третьих, вы вообще во вьюхе все правильно передаете? Плюс Iventы будут переданы как массив, поэтому в темплейте нужно их через for loop рисовать.
