使用 Django 一次更新多条记录 [英] Updating several records at once using Django

问题描述

我想在左侧创建一个带有复选框的记录列表......有点像 Gmail 中的收件箱.然后，如果用户选择了这些复选框中的一些或全部，则可以通过单击按钮来更新所选记录(顺便说一句，只会更新一个字段).

I want to create a list of records with checkboxes on the left side....kinda like the inbox in Gmail. Then if a user selects some or all of these checkboxes, then the selected record(s) can be updated (only one field will be updated BTW), possibly by clicking a button.

我被困在如何做到这一点上....想法?

I'm stuck on how to do this though....ideas?

显示代码

{% for issue in issues %}
   <tr class="{% cycle 'row1' 'row2' %}">
      <td><input name="" type="checkbox" value="{{ issue.id }}" /></td>
      <td>{{ issue.description }}</td>
      <td>{{ issue.type }}</td>
      <td>{{ issue.status }}</td>
      <td>{{ issue.date_time_added|date:"d, M Y" }}</td>
      <td>{{ issue.added_by }}</td>
      <td>{{ issue.assigned_to }}</td>
   </tr>
{% endfor %}

推荐答案

使用查询集update()方法:

id_list = list_of_ids_from_checkboxes
MyModel.objects.filter(id__in=id_list).update(myattribute=True)

您的显示 HTML 缺少复选框的 name 值.如果您在所有复选框中只有一个名称，那么 ID 列表将被传递到一个 POST 变量中，您可以直接从 request.POST(假设您将表单提交为一个帖子，你应该是):

Your display HTML is missing a name value for the checkboxes. If you just have a single name across all checkboxes, then the list of IDs will be passed into a single POST variable, which you can get straight from request.POST (assuming you're submitting your form as a post, which you should be):

id_list = request.POST.getlist('checkboxname')
