使django管理员在列表结果中显示不超过100个字符 [英] Make django admin to display no more than 100 characters in list results
问题描述
我正在为我的网站使用Django管理员,我想对我的一个模型的字段进行自定义。
我的一个模型有一个[TextField]可以是300个字符
当模型列在Django管理员中时,我想将文本显示的长度限制为100个字符。
如何实现?
admin.py:
pre>
class ApplicationAdmin(admin.ModelAdmin):
model = Application
list_display = [title1,title2]
models.py:
class Application(models.Model):
title1 = models.TextField(max_length = 300)
title2 = models.TextField(max_length = 300)
pre>
解决方案您可以显示一个在ModelAdmin类中返回字段值截断版本的属性。利用内置的模板过滤功能,可以轻松实现。
from django.template.defaultfilters import truncatechars#或truncatewords
class Foo(models.Model):
description = models.TextField()
@property
def short_description(self):
return truncatechars self.description,100)
class FooAdmin(admin.ModelAdmin):
list_display = ['short_description']
I am using Django admin for my site and I would like to make a customization on how a field is displayed for one of my models.
One of my models has a [TextField] that can be 300 characters
When the model is listed in the Django admin, I would like to limit the length of the text displayed to 100 characters.
How can I accomplish this?
admin.py:
class ApplicationAdmin(admin.ModelAdmin):
model = Application
list_display = [ "title1", "title2"]
models.py:
class Application(models.Model):
title1 = models.TextField(max_length=300)
title2 = models.TextField(max_length=300)
解决方案 You can display a property that returns a truncated version of your field's value in your ModelAdmin class. Leveraging the built-in template filters makes this easy.
from django.template.defaultfilters import truncatechars # or truncatewords
class Foo(models.Model):
description = models.TextField()
@property
def short_description(self):
return truncatechars(self.description, 100)
class FooAdmin(admin.ModelAdmin):
list_display = ['short_description']
