根据单击的datatable行将默认值设置为ForeignKey字段

Question

我的应用程序中有2个数据表，只要点击project-content-datatable行中的任何一个，就会在第二个表（content table）上显示它的子内容，现在在我的第二个表中，我有一个按钮，可以在modal中弹出一个窗体，在其中创建新的内容，在这个窗体中，我可以根据用户点击的行project-content-datatable来设置parent_project_content = models.ForeignKey(ProjectContent, on_delete=models.CASCADE)的默认值。你知道吗

非常感谢您的帮助，谢谢

这是我的密码 HTML格式

<table id="project-content-datatable" class="display table table-hover table-responsive" style="width: 100%">
    <thead>
    <tr>
        <th class="small text-muted text-uppercase"><strong>Name</strong></th>
        <th class="small text-muted text-uppercase"><strong>Description</strong></th>
    </tr>
    </thead>
    <tbody>
    {% for content in content_list %}
        {% if content.search_type.name == searchtype.name %}
            <tr class="text-primary">
                <td class="text-left" style="cursor: pointer"
                    onclick='load_workorder({{ content.id }});'>
                    {{ content.id }}
                </td>
                <td class="text-left" style="cursor: pointer" onclick='load_workorder({{ content.id }});'>
                    {{ content.name }} </td>
            </tr>
        {% endif %}
    {% endfor content_list %}
    </tbody>
</table>

你知道吗型号.py你知道吗

class WorkOrder(models.Model):
     parent_project_content = models.ForeignKey(ProjectContent, on_delete=models.CASCADE)
    description = models.TextField(default='workorder of project content', blank=True)
    assign_to = models.ForeignKey(Employee, on_delete=models.CASCADE, related_name='assign_to', null=True, blank=True)

你知道吗表格.py你知道吗

class CreateWorkorderForm(forms.ModelForm):
    class Meta:
        model = WorkOrder
        fields = ['parent_project_content','description', 'assign_to',]

你知道吗视图.py你知道吗

def content_view(request, project_id):
    """
    :param request: 
    :param project_id:

    selected_project = get_object_or_404(Project, id=project_id)
    search_type_list = selected_project.search_type.all()
    project = get_object_or_404(Project, id=project_id)
    form = CreateProjectContentForm(request.POST or None, request.FILES or None)
    workorder_form = CreateWorkorderForm(request.POST or None, request.FILES or None)

    if workorder_form.is_valid():
        instance = workorder_form.save(commit=False)
        instance.parent_project_content = WorkOrder.objects.get(parent_project_content=24)
        instance.save()

    if form.is_valid():

为处理工单表单创建一个单独的视图，在弹出工单表单的按钮上放置一个“href”，这将引导您进入处理工单提交的视图，例如：

href="{% url 'workorder_handle' pk=content.pk %}"

你的网址.py会是这样的：`

url(r'/workorder_form/(?P<pk>\d+)/$', workorder_view, name='workorder_handle'),

我在想象这里的东西，替换需要替换的东西
