Django开发中复选框用法示例

# 新增文章
def add(request):
  if request.method == 'GET':
    tags = TagModel.objects.all()
    return render(request, 'books_add.html', {'tags': tags})
  elif request.method == 'POST':
    title = request.POST.get('title', None)
    content = request.POST.get('content', None)
    blogModel = BlogModel(title=title, content=content, author=AuthorModel.objects.get(id=1))
    blogModel.save()
    # 获取复选框的值,是一个选中的数组
    tags = request.POST.getlist('tags')
    # 循环遍历所有选中的复选框,利用多对多的关系追加到数据库
    for tag in tags:
      blogModel.tag.add(tag)
    return HttpResponseRedirect('book_add')
  else:
    return HttpResponse(u'是不被处理的请求方式')

<div class="form-group">
  <label class="col-sm-2 control-label">标签</label>
  <div class="col-sm-9">
    {% for tag in tags %}
      <label class="checkbox-inline">
        <input value="{{ tag.id }}" type="checkbox" name="tags"/>{{ tag.name }}
      </label>
    {% endfor %}
  </div>
</div>

# 编辑博客
def edit(request, blog_id):
  tags = TagModel.objects.all()
  # 利用正向查找关于本博客选择的tag
  blogModel = BlogModel.objects.filter(id=blog_id).first()
  # 获取全部的tag
  check_tag = blogModel.tag.all()
  # 获取选中的id
  check_id = [int(x.id) for x in check_tag]
  print check_id
  return render(request, 'books_edit.html', {'tags': tags, 'check_id': check_id})

<div class="form-group">
  <label class="col-sm-2 control-label">标签</label>
  <div class="col-sm-9">
    {% for tag in tags %}
      {% if tag.id in check_id %}
        <label class="checkbox-inline">
