Update the process_students function to return a list of processed student data:
def process_students(students):
processed_students = []
for student in students:
# Perform processing on each student object
processed_student = {
'name': student.name,
'age': student.age,
'grade': student.grade
}
processed_students.append(processed_student)
return processed_students
Update the main_function to pass the processed student data to the template:
from django.shortcuts import render
def main_function(request):
students = get_students()
processed_students = process_students(students)
return render(request, 'template.html', {'students': processed_students})
Create a template file called template.html in your app's template directory (e.g., myapp/templates/template.html):
<html>
<head>
<title>Student Data</title>
</head>
<body>
<h1>Student Data</h1>
<ul>
{% for student in students %}
<li>Name: {{ student.name }}, Age: {{ student.age }}, Grade: {{ student.grade }}</li>
{% empty %}
<li>No students found.</li>
{% endfor %}
</ul>
</body>
</html>
In this template, we use a for loop to iterate over the students list and display each student's name, age, and grade. If no students are found, it displays a message.
Now, when you access the URL associated with main_function (e.g., /my-url/), it will retrieve the student data, process it, and render the data in the template.html template.
You want to retrieve student data from the database in one function (get_students) and then pass that data to another function (process_students) for further processing. Here's a step-by-step example:
Create a Django project and app (if not already created).
Define your Student model in models.py:
from django.db import models
class Student(models.Model):
name = models.CharField(max_length=100)
age = models.IntegerField()
grade = models.CharField(max_length=10)
Open the views.py file in your app directory.
Define the get_students function to retrieve student data from the database:
from .models import Student
def get_students():
students = Student.objects.all()
return students
Define the process_students function to process the retrieved student data:
def process_students(students):
for student in students:
# Perform processing on each student object
print(f"Processing student: {student.name}, Age: {student.age}, Grade: {student.grade}")
Define the main function, main_function, that calls both get_students and process_students:
def main_function():
students = get_students()
process_students(students)
Optionally, you can pass arguments and return values between functions as needed.
Save the views.py file.
Finally, you can trigger the execution of main_function through a URL or any other entry point of your Django application.
For example, if you have a URL pattern associated with main_function in your urls.py file, accessing that URL will trigger the execution of both get_students and process_students.
from django.urls import path
from . import views
urlpatterns = [
path('my-url/', views.main_function, name='main_function'),
]
Accessing the URL /my-url/ will call the main_function, which, in turn, calls get_students to retrieve the student data and then passes it to process_students for further processing.
