Django Admin列表页：将模型方法返回值改为显示Yes/No而非图标

Got it, let's fix this for you! When you set boolean=True on your model method, Django Admin automatically renders those boolean values as green/red icons. To show "Yes/No" text instead, you have a couple of straightforward options depending on your needs:

Option 1: Modify the Model Method to Return Text Directly #

If you don't need the method to return a boolean value for other parts of your code, you can adjust it to return "Yes" or "No" strings, and set a clear display name for the Admin column:

from django.utils import timezone
import datetime

class Question(models.Model):
    pub_date = models.DateTimeField('date published')

    def was_published_recently(self):
        now = timezone.now()
        is_recent = now - datetime.timedelta(days=1) <= self.pub_date <= now
        return "Yes" if is_recent else "No"
    
    # Set the column name that shows up in Admin
    was_published_recently.short_description = 'Published Recently?'

Just remove the was_published_recently.boolean = True line — without this flag, Django Admin will render the returned string directly instead of using icons.

Option 2: Keep the Boolean Method, Add a Display Wrapper in Admin #

If you still need the was_published_recently method to return a boolean (for other logic in your app), you can create a separate display method in your Admin class to handle the "Yes/No" conversion:

from django.contrib import admin
from .models import Question

class QuestionAdmin(admin.ModelAdmin):
    # Use our custom display method instead of the original boolean method
    list_display = ('pub_date', 'published_recently_display')

    def published_recently_display(self, obj):
        # Reuse the existing boolean method and convert to text
        return "Yes" if obj.was_published_recently() else "No"
    
    # Set the column name for Admin
    published_recently_display.short_description = 'Published Recently?'

admin.site.register(Question, QuestionAdmin)

Bonus: Add Colored Text for Better Visibility #

If you want to keep the visual clarity of the original icons but use text, you can use format_html to add color styling:

from django.utils.html import format_html
from django.contrib import admin
from .models import Question

class QuestionAdmin(admin.ModelAdmin):
    list_display = ('pub_date', 'published_recently_display')

    def published_recently_display(self, obj):
        if obj.was_published_recently():
            return format_html('<span style="color: #2ecc71; font-weight: bold;">Yes</span>')
        else:
            return format_html('<span style="color: #e74c3c; font-weight: bold;">No</span>')
    
    published_recently_display.short_description = 'Published Recently?'

admin.site.register(Question, QuestionAdmin)

This gives you colored text that's easy to scan, just like the original icons but with your preferred text labels.
