Django嵌套在线表格 [英] Django Nested Inline Formsets

问题描述

我正在努力解决问题，但我不知道如何面对这个问题。我需要一些帮助： - ）

I'm trying to solve a problem, but I have no idea how to face it. I need some help :-)

我有一个这样的模型层次：

I have a model hierarchy like this:

class Task(models.Model):
    name = models.CharField(max_length=255)
    number_of_steps = models.IntegerField()

class StepGroup(models.Model):
    task = models.ForeignKey(Task)
    init_date = models.DateField()

class Step(models.Model):
    group = models.ForeignKey(StepGroup)
    name = models.CharField(max_length=255)

我必须写一个对话框，我创建了一些步骤组。一个InlineFormSet看起来很方便，但是由于有两个层次的嵌套，我不知道该怎么做。

I must write a dialog where I create a number of Step Groups. An InlineFormSet looks the way to go, but as there are two levels of nesting, I don't know how to do that.

此外，我需要通常的东西形式：错误控制（form.name_of_field.errors），编辑任务等时自动填充，因此手动执行JavaScript和服务器端处理POST请求将会太复杂和容易出错。

Besides, I need the usual stuff with forms: error control (form.name_of_field.errors), autopopulation when editing the Task, etc, so doing it manually with javascript and server-side handling of the POST request would be too complicated and error-prone.

这是我需要表单的方式（每个组中的步骤数量由任务模型中的number_of_steps字段设置）：

This is the way I need the form (the number of steps in each group is set by the "number_of_steps" field in the Task model):

+-----------------------------------+
| STEP GROUP 1                      |
|                                   |
| Init date: _____________          |
|                                   |
| Step 1: ________________          |
| Step 2: ________________          |
| Step 3: ________________          |
|                                   |
+-----------------------------------+
| STEP GROUP 2                      |
|                                   |
| Init date: _____________          |
|                                   |
| Step 1: ________________          |
| Step 2: ________________          |
| Step 3: ________________          |
|                                   |
+-----------------------------------+
|                                   |
|             +-------------------+ |
|             | Create step group | |
|             +-------------------+ |
+-----------------------------------+
