这就是我尝试过的。它可以工作,但额外的字段text1呈现为一个普通的输入字段,没有标签,也没有很酷的wagtail渲染。如何在表单中添加额外的字段并获得很酷的wagtail渲染?
以下是WagtailAdminPageForm文档的link:
class Review(models.Model):
page = models.OneToOneField(
'wagtailcore.Page',
verbose_name=('page'),
related_name='review',
on_delete=models.CASCADE)
text1 = models.CharField(null=True, blank=True, max_length=50)
class RandomPageForm(WagtailAdminPageForm):
""" Custom form for RandomPage """
text1 = forms.CharField() # <-- extra field here!
def __init__(self, data=None, files=None, parent_page=None, *args, **kwargs):
super(RandomPageForm, self).__init__(data, files, *args, **kwargs)
if self.instance.id:
review, created = Review.objects.get_or_create(page_id=self.instance.id)
print "set form.text1 to model.text1"
self.fields['text1'].initial = review.text1
# !!! Below has no effect
self.instance.content_panels = Page.content_panels + [
FieldPanel('body'),
FieldPanel('text1'),
]
def save(self, commit=True):
page = super(RandomPageForm, self).save(commit=False)
review, created = Review.objects.get_or_create(page=page)
review.text1 = self.data["text1"]
review.save()
return page
class RandomPage(Page):
body = RichTextField(blank=True)
content_panels = Page.content_panels + [
FieldPanel('body', classname="full"),
]
base_form_class = RandomPageForm

基于每个实例编辑面板定义不会起作用,因为面板定义被编译为在类级别缓存的EditHandler
对象:https://github.com/wagtail/wagtail/blob/48949e69a7a7039cb751f1ee33ecb32187004030/wagtail/wagtailadmin/edit_handlers.py#L804
对于您发布的代码段,看起来将FieldPanel('text1')
移动到RandomPage
的content_panels片段应该可以完成这项工作(虽然我从未尝试过使用非模型字段。)

我刚刚意识到片段可能会解决我的问题。这听起来正是我需要的。所以我将我的非页面模型注册为片段并获得wagtaill渲染。我会检查一下并确认。
