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':    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">          <input value="{{ tag.id }}" type="checkbox" name="tags" checked="checked"/>{{ tag.name }}        </label>      {% else %}        <label class="checkbox-inline">          <input value="{{ tag.id }}" type="checkbox" name="tags"/>{{ tag.name }}        </label>      {% endif %}    {% endfor %}  </div></div>

$('#btn').on('click', function (e) {  // 设置空数组  var hobby = [];  $('#hobby-group').find('input[type=checkbox]').each(function () { if ($(this).prop("checked")) {   var hobbyId = $(this).val();   hobby.push(hobbyId); }  })  console.log(hobby);  $.ajax({ 'url': '/ajaxpost/', 'method': 'post', 'data': {   'username': $('.username').val(),   'hobby': hobby }, 'traditional': true, 'beforeSend': function (xhr, settings) {   var csrftoken = ajaxpost.getCookie('csrftoken');   //2.在header当中设置csrf_token的值   xhr.setRequestHeader('X-CSRFToken', csrftoken); }, 'success': function (data) {   console.log(data); }  })})

@require_http_methods(['POST'])def ajaxpost(request):  form = LoginForm(request.POST)  if form.is_valid():    username = form.cleaned_data.get('username', None)    # 获取复选框的值    hobby = request.POST.getlist('hobby')    print '*' * 100    print hobby    print '*' * 100    return HttpResponse(u'成功')  else:    return HttpResponse(u'验证错误')
