django-如何为几乎相同的模型重用模板？ [英] django - how to reuse a template for nearly identical models?

问题描述

对于django和python还是很新的。

Still fairly new to django and python.

我定义了两个几乎相同的从基类继承的模型：

I've defined two nearly identical models that inherit from a base class:

class addressbook(models.Model):
    name = models.CharField(max_length=50)

class company(addressbook):
    address = models.CharField(max_length=50)

class contact(addressbook):
    telephone - models.CharField(max_length=30)

我想对公司和联系对象做非常相似的事情。但是在我的模板中，我似乎需要为每个对象使用单独的模板，因为要访问对象中的成员，我必须使用类似的

I want to do very similar things with company and contact objects. However in my templates it looks like I need to use separate templates for each object since to access the members in the object I have to use something like

{{ blah.name }} {{ blah.address}}

{{ blah.name }} {{ blah.telephone}} 

其他。

所有这些重复使我感到怀疑。是否有一些python或django模板语法可以让我在两个模型中重用单个模板（具有某种内置的智能功能）？

All this repetition makes me suspicious. Is there some python or django template syntax that would allow me to reuse a single template (with some sort of built in intelligence) with both models?

感谢您的帮助！

推荐答案

如果您在模型中创建一个属性，该属性指示每种类型的特定关注领域，这样您就可以在模板中使用一个变量。示例：

If you create a property in your models that indicates the specific field of interest for each type, that would let you use one variable in a template. Example:

class addressbook(models.Model):
    name = models.CharField(max_length=50)

class company(addressbook):
    address = models.CharField(max_length=50)

    @property
    def display_field(self):
        return self.address

class contact(addressbook):
    telephone = models.CharField(max_length=30)

    @property
    def display_field(self):
        return self.telephone

现在您可以在模板中使用{{等等。 display_field}}，它将根据对象类型显示所需的值。

Now in your template you can use {{ blah.display_field }} and it will print the value you want, depending on the object type.
