Remove objects from associated models in Django template

[Rossere]

I'm doing your Django transmission program.

models

class TVChannel(models.Model):
"""TV канал"""
   title = models.CharField("Название TV канала", max_length=50, unique=True)
   logo = models.ImageField(upload_to='channels/logo/', blank=True, null=True)
   description = models.TextField("Описание TV канала", max_length=3000, blank=True, null=True)
   slug = models.SlugField(max_length=50, unique=True)
def str(self):

return f"{self.title}"
class Meta:

verbose_name = "TV канал"

verbose_name_plural = "TV каналы"
class Region(models.Model):

"""Регион вещания"""

title = models.CharField("Регион вещания", max_length=100, unique=True)

description = models.TextField("Описание страницы региона", max_length=1000, blank=True, null=True)

slug = models.SlugField(max_length=100, unique=True)
def str(self):

return f"{self.title}"
def get_absolute_url(self):

return reverse('slug', kwargs={'slug': self.slug})
class Meta:

verbose_name = "Регион вещания"

verbose_name_plural = "Регионы вещания"
class TVShow(models.Model):

"""Телевизионная программа"""

title = models.CharField("Название передачи", max_length=150)

date = models.DateField("Дата трасляции")

time = models.TimeField("Время трасляции")

channel = models.ForeignKey(TVChannel, on_delete=models.CASCADE, verbose_name="TV канал", related_name='channel_rn')

region = models.ForeignKey(Region, on_delete=models.CASCADE, verbose_name="Регион вещания", related_name='region_rn')
def str(self):

return f"{self.title}"
class Meta:

verbose_name = "TV передача"

verbose_name_plural = "TV передачи"

views

class RegionTodayView(DetailView):

"""ТВ передачи региона"""

today = tvProgramToday()

model = Region

slug_field = 'slug'

template_name = 'tvprogram/region_today_detail.html'

def get_context_data(self, **kwargs):

context = super(RegionTodayView, self).get_context_data(**kwargs)

context['tvshow'] = TVShow.objects.filter(region=self.get_object()).filter(date=self.today).order_by('time')

context['tvchannel'] = TVChannel.objects.order_by('id')

return context

template

{% for channel in tvchannel %}

<div class="col-12 col-md-6 col-lg-4">

<div class="channel">

<div class="channel__item channel__item--first"><span>{{ channel.title }}</span></div>

{% for item_tvshow in tvshow %}

<div class="price__item"><span>{{ item_tvshow.time }}</span><span>{{ item_tvshow.title }}</span></div>

{% endfor %}

</div>

</div>

{% endfor %}

In this form, every channel is displayed by all your show:

Can you tell me, please, how do you write in a box so that each canal gets a show connected only to this channel?

I don't know why you're going to be alone. views Total context tvshow. T.K. model TVShow related to the model TVChannel

context['tvshow'] = TVShow.objects.filter(region=self.get_object()).filter(date=self.today).order_by('time')

But something like that should work.

{% for channel in tvchannel %}
<div class="col-12 col-md-6 col-lg-4">
     <div class="channel">
         <div class="channel__item channel__item--first"><span>{{ channel.title }}</span></div>
         {% for item_tvshow in channel.channel_rn.all%}
         <div class="price__item"><span>{{ item_tvshow.time }}</span><span>{{ item_tvshow.title }}</span></div>
         {% endfor %}
     </div>
 </div>
{% endfor %}

related models are used related_name♪
