How to deduce relationships with Foreign Key from the model?

Question

Django

There is a model

lass Cruski(models.Model):
    name = models.CharField(max_length=40)
    description = models.TextField(default='Описание кружка')
    price = models.IntegerField(default=0)
    def __str__(self):
        return self.name

class Vospitately(models.Model):
    fio = models.CharField(max_length=40)
    dolshnost = models.CharField(max_length=80, default='Должность..')
    image = models.ImageField()
    vospet_crushek = models.ForeignKey(Cruski)
    def __str__(self):
        return self.fio

views.py

def kruzhki(request):
    q = Cruski.objects.all()
    p = Vospitately.objects.filter(vospet_crushek_id=?)
    return render(request,'krushki.html',{'kruzki':q, 'vospitately':p})

sample

{% block kruzhki %}
{% for krug in kruzki %}
<p><b>{{ krug.name }}</b></p>
{% for vospet in vospitately %}
<p> {{ vospet.fio }}</p>
{% endfor %}
<p>{{ krug.description }}</p>
<p>{{ krug.price }}</p>
{% endfor %}

How can I link in the model view so that infa is displayed from one and the other model by id?

Answer 1

Snachala nado opredelit related_name dlya Vospitately.vospet_crushek

class Vospitately(models.Model):
    fio = models.CharField(max_length=40)
    dolshnost = models.CharField(max_length=80, default='Должность..')
    image = models.ImageField()
    vospet_crushek = models.ForeignKey(Cruski', related_name='vospitately')
    def __str__(self):
        return self.fio

Potom vo view mogno tak sdelat

def kruzhki(request):
    q = Cruski.objects.all()
    return render(request,'krushki.html',{'kruzki':q})

I nakonec v shablone pishem what to po tipu takogo

{% block kruzhki %}
{% for krug in kruzki %}
<p><b>{{ krug.name }}</b></p>
{% for vospet in krug.vospitately.all %}
<p> {{ vospet.fio }}</p>
{% endfor %}
<p>{{ krug.description }}</p>
<p>{{ krug.price }}</p>
{% endfor %}

Vot i vse. Takim obrazom u nas vivoditsya krugki i vospitately kotorie v nis sostoyat.
Kstati vam bi opredelitsya stoit kak pisat "cups":
- Cruski
- vospet_crushek
- kruzhki
- kruzki
- krushki.html
