Models.py

from django.db import models

# Create your models here.

class students(models.Model):
    firstname = models.CharField(max_length=50)
    lastname = models.CharField(max_length=50)
    fathername = models.CharField(max_length=50)
    city = models.CharField(max_length=50)
    country = models.CharField(max_length=50)
    state = models.CharField(max_length=50)
    zip = models.IntegerField(blank=True)
    address = models.CharField(max_length=100)
    contact =models.CharField(max_length=20)
    photo = models.ImageField(upload_to='images/', height_field=None, width_field=None, max_length=None)

urls.py

from django.urls import path, include
from home import views
from django.contrib import admin
from home import StudentViews
from django.conf.urls.static import static
from django.conf import settings



urlpatterns = [
    path("", views.index, name="index"),
    path("Add_Student", views.Add_Student, name="Add_Student"),
    path("display_students", views.Display_Student, name="display_students"),
    path("<int:id>", views.student_profile, name="student_profile"),
    #path("student/<int:id>/view", views.student_profile, name="student_profile"),

    path("Student_Home", StudentViews.StudentHome, name="Student_Home")
    
]

#this line is for media 
urlpatterns += static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

settings.py

在 settings.py 中，我添加了以下代码行.

In settings.py, I added the following lines of code.

MEDIA_ROOT= os.path.join(BASE_DIR, 'media/images')
MEDIA_URL= "/images/"

我的目录

Student_Management_System

Student_Management_System

• 家
• 媒体/图片
• 模板
• 静态

注意:我已经安装了 Pillow.

Note: I have already installed Pillow.

views.py

这是我的视图 Add_Student 将条目添加到数据库中.

Here is my view Add_Student that add the entry into database.

from django.shortcuts import render, redirect
from home.models import students

# Create your views here.

def index(request):
    return render(request, "index.html")

def Add_Student(request):
    if request.method == 'POST':
        firstname = request.POST.get('firstname')
        lastname = request.POST['lastname']
        fathername = request.POST['fathername']
        city = request.POST['city']
        country = request.POST['country']
        state = request.POST['state']
        zipcode = request.POST['zip']
        address = request.POST['address']
        contact = request.POST['contact']
        photo = request.POST['photo']

        Add_Student = students.objects.create(firstname=firstname, lastname=lastname, fathername=fathername, city=city,country=country, state=state, zip=zipcode, address=address, contact=contact, photo=photo)
        Add_Student.save()
        return redirect('Add_Student')
    else:
        return render(request, 'student/Add_Student.html')

推荐答案

更新您的 MEDIA_ROOT

MEDIA_ROOT= os.path.join(BASE_DIR, 'your_app_name/media')

您可以阅读文档 第2点

定义 upload_to 选项指定用于上传文件的 MEDIA_ROOT 子目录.

defining the upload_to option specifies a subdirectory of MEDIA_ROOT to be used for uploaded files.

还要确保您已将 enctype="multipart/form-data"form 属性添加到您的模板中，如 文档

Also make sure that you have added enctype="multipart/form-data"form attribute to your template as mentioned here in the documentation

请注意，如果请求方法是 POST 并且发布请求的方法具有属性 enctype=multipart/form-data"，则 request.FILES 将仅包含数据.否则 request.FILES 将为空.

Note that request.FILES will only contain data if the request method was POST and the that posted the request has the attribute enctype="multipart/form-data". Otherwise, request.FILES will be empty.

在Add_student 视图中也有一点变化

Also a little change in Add_student view

photo = request.FILES['photo']

Add_Student.save() # NO need to use this. create() creates and saves the object at the same time.
