在Django博客应用中插入多张图片可以通过以下步骤实现:
from django.db import models
class Blog(models.Model):
title = models.CharField(max_length=100)
images = models.ManyToManyField('Image')
class Image(models.Model):
image = models.ImageField(upload_to='blog_images/')
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
from django.shortcuts import render, redirect
from .forms import BlogForm
def create_blog(request):
if request.method == 'POST':
form = BlogForm(request.POST, request.FILES)
if form.is_valid():
blog = form.save()
return redirect('blog_detail', pk=blog.pk)
else:
form = BlogForm()
return render(request, 'create_blog.html', {'form': form})
from django import forms
from .models import Blog
class BlogForm(forms.ModelForm):
class Meta:
model = Blog
fields = ('title', 'images')
widgets = {
'images': forms.ClearableFileInput(attrs={'multiple': True}),
}
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Create Blog</button>
</form>
通过以上步骤,你就可以在Django博客应用中插入多张图片了。用户可以在博客文章创建的表单中选择多张图片进行上传,并且这些图片将会与相应的博客文章关联起来。你可以根据具体的需求,在模板中显示这些图片,并在博客详情页面中展示它们。
