Django Admin轉義文本

Question

我最近將Django從1.3升級到了1.8.18，並且在Django admin中對預填充表單的鏈接進行了定製。例如，我有以下鏈接：

/admin/miscellaneous/whatsnew/add/?title=...%20competition%20results%20uploaded&pub_date=21-04-2017&body=&link= 

執行時預填充數據的形式如下：

，它應該是這樣的：

當直接從Safari的URL欄進行測試時，按下回車鍵後會更改爲：

https://flyball.org.au/admin/miscellaneous/whatsnew/add/?title=...%2520competition%2520results%2520uploaded&pub_date=21-04-2017&body=&link= 

models.py

class WhatsNew(models.Model): 
    title = models.CharField(max_length=100,help_text='Title, MAX 100 characters.') 
    body = models.TextField() 
    pub_date = models.DateField() 
    message_expiry = models.DateField(default=datetime.date.today() + relativedelta(years=1)) 
    link = models.URLField(blank=True, null=True) 

    class Meta: 
     ordering = ['-pub_date'] 
     verbose_name_plural = "Whats New?" 

    def __unicode__(self): 
     return self.title 

admin.py

import models 
from django.contrib import admin 

class WhatsNewAdmin(admin.ModelAdmin): 
    list_display = ('title','pub_date','message_expiry','link','body') 

admin.site.register(models.WhatsNew, WhatsNewAdmin) 

我能做些什麼來解決這個問題？

Answer 1

使用+而不是%20空間和它的作品。

你的鏈接應該是這樣的：

/admin/miscellaneous/whatsnew/add/?title=...+competition+results+uploaded&pub_date=21-04-2017&body=&link=

因此，我不確定如何在ModelAdmin上做到這一點，但是您可以在模型上創建自定義setter來處理這種情況。這是我怎麼會去逃避URL編碼的字符串：

import urllib 


class WhatsNew(models.Model): 
    # Field with custom setter 
    _title = models.CharField(max_length=100, 
          help_text='Title, MAX 100 characters.', 
          db_column='title') 

    body = models.TextField() 
    pub_date = models.DateField() 
    message_expiry = models.DateField(default=datetime.date.today() + relativedelta(years=1)) 
    link = models.URLField(blank=True, null=True) 

    # Custom getter and setter 
    @property 
    def title(self): 
     return self._title 

    @title.setter 
    def title(self, value): 
     self._title = urllib.unquote(value) 

    class Meta: 
     ordering = ['-pub_date'] 
     verbose_name_plural = "Whats New?" 

    def __unicode__(self): 
     return self._title
