Django DetailView don't show data in template-CodePudding

Hello I'm just starting use the CBV in Django. My ListView working normal it can get the id in models except DetailView. It don't show the detail data.[https://drive.google.com/file/d/17yeU-LdvV_yLjnBB2A2gYt5ymSeKvPAR/view?usp=sharing][1]

Here the code:

models.py:

class School(models.Model):
name = models.CharField(max_length=125)
principal = models.CharField(max_length=125)
location = models.CharField(max_length=125)

def __str__(self):
    return self.name

class Student(models.Model):
    name = models.CharField(max_length=70)
    age = models.PositiveIntegerField()
    school = models.ForeignKey(School,related_name='students',on_delete=models.CASCADE)

    def __str__(self):
        return self.name

views.py:

class School_List(ListView):
context_object_name = 'schoollist'
model = School

class School_Detail(DetailView):
    contex_object_name = 'schooldetail'
    model = Student
    template_name = 'basicapp/School_detail.html'

detail.html:

{% block content %}
    <h1>Site showing School Detail</h1>
    <div >
        <div >
            <p>Name: {{schooldetail.name}}</p>
            <p>Principal: {{schooldetail.principal}}</p>
            <p>Location: {{schooldetail.location}}</p>
            <h2>Student: </h2>
            {% for student in schooldetail.students.all %}
                <p>{{student.name}} who is {{student.age}} years old</p>
            {% endfor %}
        </div>
    </div>
{% endblock %}

Thank you

In School_Detail you use Student as Model instead of School Model.

Change your Model from Student to School as

class School_Detail(DetailView):
    contex_object_name = 'schooldetail'
    model = School                       #<---- change model name here
    template_name = 'basicapp/School_detail.html'

CodePudding user response：

it should be {{schooldetail.school.name}} not {{schooldetaill.name}} as you using Student model in your details views so you can access School model via your foreign key fields of Student model.

{% block content %}
        <h1>Site showing School Detail</h1>
        <div >
            <div >
                <p>Name: {{schooldetail.school.name}}</p>
                <p>Principal: {{schooldetail.school.principal}}</p>
                <p>Location: {{schooldetail.school.location}}</p>
                <h2>Student: </h2>
                {% for student in schooldetail.students.all %}
                    <p>{{student.name}} who is {{student.age}} years old</p>
                {% endfor %}
            </div>
        </div>
    {% endblock %}
