django - 创建一个可以为同一个字段插入多个值的模型？ [英] django - create a model that lets you insert multiple values for the same field?

问题描述

好吧，我想做一些在我心中应该非常简单的事情，但是我可能会丢失一些SQL或django管理员的知识。
说我有一个简单的模型，如

  class Book（models.Model）：
 title = models.CharField（max_length = 50）
 review = models.TextField（）
  

和我希望管理员网站中的评论字段有一点加号，可以向模板实例添加更多评论，以便模板遍历它们。

我知道我可以为评论创建一个m2m字段，它会给我这样的，但我宁愿那些额外的评论可以从同一页面填写没有弹出窗口（对于我无奈的用户，我希望将它保持为WSIWYG，因为这些文本框将是tinyMCE的），我想知道是否真的有必要为文本框创建一个额外的模型

解决方案

创建一个审查模型，其中包含审阅文本，并具有 ForeignKey to Book ...

  class Book（models.Model）：
 title = models.CharField（）
 
 class Review（models.Model）：
 book = models.ForeignKey（Book，related_name ='reviews '）
 review = models.TextField（）
  

...然后注册相应的类型的 InlineModelAdmin 可以在管理员的书页上编辑所有相关评论。在这种情况下，我建议使用 StackedInline ：

  class ReviewInline （admin.StackedInline）：
 model =评论
 
 class BookAdmin（admin.ModelAdmin）：
 inlines = [
 ReviewInline，
] 
  

文档中有几个这个确切情况的例子，除了多个作者，而不是多个评论：

Ok I'm trying to do something which should be very simple in my mind but I am probably missing some SQL or django admin knowledge to get to it. Say I have a simple model such as

class Book(models.Model):
    title = models.CharField(max_length = 50)
    review = models.TextField()

and I want the 'review' field in the admin site to have a little plus sign to add more reviews to the same model instance for the template to iterate through them.

I know I could create a m2m field for the reviews and it would give me just that, but I would rather like that those extra reviews could be filled from the same page without popups (for my helpless users i would like to keep it as WSIWYG as possible, since those textfields will be tinyMCE powered), and I wonder if it's really necessary to create an extra model just for a textfield

解决方案

Create a Review model which holds the review text and has a ForeignKey to Book...

class Book(models.Model):
   title = models.CharField()

class Review(models.Model):
   book = models.ForeignKey(Book, related_name='reviews')
   review = models.TextField()

...then register the appropriate type of InlineModelAdmin to edit all the related reviews on the Book's page in the admin. I'd suggest using a StackedInline in this case:

class ReviewInline(admin.StackedInline):
    model = Review

class BookAdmin(admin.ModelAdmin):
    inlines = [
        ReviewInline,
    ]

The documentation has an example of almost this exact scenario, except for multiple authors instead of multiple reviews:
