问题描述
我有一个场景,我正在尝试计划开始编码,我正在考虑使用 django 向导
.
I have a scenario which I'm trying to plan to start coding and I'm thinking to use django wizard
.
我的计划是用两个步骤构建一个 django 向导,第一个简单但第二个稍微复杂一些.第二步将包含一个表单,该表单将根据从第一步中选择的值进行重塑,我可以看到自己正在这样做.我已经探索了所有现有的功能,我认为它可以轻松完成.
My plan is to build a django wizard with two steps, the first simple but the second a bit more complicated. The second step will contain a form that will reshape based on value selected from the first step, which I can see myself doing. I already explored all the existing functionality and I think it can be done easily.
不过,我面临的挑战是第二步本身.我有一个表单和一个表单集,表单集是一对多的(文章-> 图像),因此当到达第二步时,用户将能够将一个或多个图像上传到同一篇文章.
The challenge I'm facing though, is that in the second step itself. I have a form and a formset, the formset is one to many to form (Article -> Images) so when reaching the second step the user will be able to upload one or more images to the same article.
我试图在 google 邮件列表和 stackoverflow 上到处搜索以将表单集传递给 django 向导类,但似乎您无法在同一步骤中传递两个表单.
I tried to search everywhere on google mailing lists and stackoverflow for passing a formset to the django wizard class but it seems like you can not pass two forms in the same step.
NewItemWizard.as_view([
('category', CategorySelectionForm),
('article', ArticleForm)
])
如上所示,在上面的示例代码中,我希望能够将 ArticleForm 和 ImageFormset 都传递到第二步.有没有办法做到这一点?
as seen, in the example code above, I would like to be able to pass both ArticleForm and ImageFormset to the second step. Is there a way to do this out of the box?
根据我正在阅读的内容,我相信使用像 get_context_data 这样的函数会有所帮助,但它会非常笨拙.
Based on what I'm reading, I believe using a function like get_context_data could help, but it will be very hacky.
def get_context_data(self, form, **kwargs):
context = super(NewItemWizard, self).get_context_data(form=form, **kwargs)
if self.steps.current == 'article':
context.update({
'image_formset': ImageFormset()
})
return context
有人可以建议更好的方法吗?
Anyone can advise for a better approach?
干杯,
推荐答案
目前还没有直接的 API 来做这件事,但是有一个像这里提到的那样的干净的解决方案:
There is no straight API to do it yet, but there is a clean solution like the one mentioned here:
