如何在Django中更改个人资料图片？

Question

我正在尝试开发一个社交网站，并且在我的用户个人资料页面中，我想显示用户从注册页面中选择的图像。我在媒体文件夹中提供了default.jpg，以防用户不想上传图片。

但是，每次我尝试注册新用户时，即使我选择其他图像，也会显示默认图像。我该如何解决？

我的模型。py

from django.db import models
from django.contrib.auth.models import User
from PIL import Image

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')
    CHOICES = (
        ('AB+', 'AB+'),
        ('AB-', 'AB-'),
        ('A+', 'A+'),
        ('A-', 'A-'),
        ('B+', 'B+'),
        ('B-', 'B-'),
        ('O+', 'O+'),
        ('O-', 'O-'),
        )
    bloodgroup = models.CharField(max_length=100, choices= CHOICES)
    bio = models.TextField(max_length=300)

    def __str__(self):
        return f'{self.user.username} Profile'


    def save(self):
        super().save()

        img = Image.open(self.image.path)

        if img.height > 300 or img.width > 300:
            output_size = (300, 300)
            img.thumbnail(output_size)
            img.save(self.image.path)

我的forms.py

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
from .models import Profile


class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']



class ProfileForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ('image', 'bloodgroup', 'bio')


class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ['username', 'email']

class ProfileUpdateForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ['image', 'bloodgroup', 'bio']

我的profile.html

{% extends "blog/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
    <div class="content-section">
      <div class="media">
        <img class="rounded-circle account-img" src="{{ user.profile.image.url }}">
        <div class="media-body">
          <h2 class="account-heading">{{ user.username }}</h2>
          <p class="text-secondary">{{ user.email }}</p>
          <p class="text-secondary">Bloodgroup : {{ user.profile.bloodgroup }}</p>
          <p class="text-secondary">Bio - {{ user.profile.bio }}</p>
        </div>
      </div>
      <form method="POST" enctype="multipart/form-data">
           {% csrf_token %}
           <fieldset class="form-group">
               <legend class="border-bottom mb-4">Profile Info</legend>
               {{ u_form|crispy }}
               {{ p_form|crispy }}
           </fieldset>
           <div class="form-group">
               <button class="btn btn-outline-info" type="submit">Update</button>
           </div>
       </form>
    </div>
{% endblock content %}
