filter_horizontal
功能消失了。我尝试在Chrome无痕模式下查看我的管理页面,一些答案建议这样做,我还尝试将
verbose_name
字符串更改为unicode。然而,这些方法都没有奏效。这是一个模型的示例,我正在尝试显示其中的
filter_horizontal
。在升级之前,这在我的应用程序上可以正常工作。
admin.py
class ResearchAdmin(admin.ModelAdmin):
filter_horizontal = ('criteria', 'state')
def save_model(self, request, obj, form, change):
obj.save()
# Update cache for tasks containing the saved goal
tasks = Task.objects.filter(research__id=obj.pk).values_list('pk', flat=True)
for t in tasks:
cache.delete_many(['task%s' % t, 'task%s_research' % t])
models.py
"""
Clinical Research model
"""
def __str__(self):
return "%s" % (self.name)
name = models.CharField(max_length=50, null=True, blank=True)
type = models.CharField(max_length=50, null=True, blank=True)
cta = models.CharField(max_length=50, null=True, blank=True)
description = models.TextField(null=True, blank=True)
picture = models.ImageField(upload_to='images/%Y/%m/%d', null=True, blank=True, help_text="Upload portrait image for modal study description")
layout = models.CharField(max_length=1, choices=LAYOUT_TYPE, null=False, blank=False, default='r')
criteria = models.ManyToManyField('Answer', blank=True, db_index=True, help_text="Answers required for qualified patients")
required_contact = models.ManyToManyField('ContactField', blank=True, db_index=True, help_text="Contact info for patient to enter")
email = models.EmailField(null=True, blank=True, help_text="Sponsor email for notifying of screened patients")
link = models.URLField(null=True, blank=True)
state = models.ManyToManyField('State', blank=True, help_text="Qualifying states")
lat = models.CharField(max_length=60, null=True, blank=True)
lng = models.CharField(max_length=60, null=True, blank=True)
distance = models.PositiveIntegerField(null=True, blank=True, help_text="Maximum distance from user in miles to show")
class Meta:
verbose_name = u"Research"
verbose_name_plural = u"Research"
没有错误信息,但是criteria
和state
字段的filter_horizontal
前端在管理界面中没有显示出来。
##collectstatic##
正如@iain-shelvington所建议的那样,这个问题可能是由于与显示filter_horizontal
格式所需的缓存前端代码的某种干扰导致的。我尝试在Google隐身模式下运行,清除缓存,并运行collectstatic --clear
,但这些都没有起作用。此外,在升级前后的管理静态文件之间没有任何区别。
@SylvainBiehler指出django_gulp
可能会覆盖collectstatic。我禁用了django_gulp
并运行了./manage.py collectstatic --clear
,所有管理文件现在在Django
升级后都已更新。
##比较Django升级前后的管理文件##
我能够启动一个Django升级前的版本的应用程序,旧版本中的filter_horizontal
功能是有效的。从Chrome控制台中Criteria
字段的构造中存在一些差异:
旧版本(有效)
选择选项之前的元素:<select multiple="multiple" class="selectfilter" id="id_criteria" name="criteria">
选择后的Javascript:
<script type="text/javascript">addEvent(window, "load", function(e) {SelectFilter.init("id_criteria", "criteria", 0, "https://xxxxxxx/static/admin/"); });</script>
新版本(已损坏)
选择元素稍有不同。在选项后没有javascript:
<select name="criteria" id="id_criteria" multiple class="selectfilter" data-field-name="criteria" data-is-stacked="0">
这似乎是导致问题的原因,但我不知道如何解决。有什么想法吗?

SelectBox.js
和SelectFilter2.js
是否已加载?这两个文件用于显示水平小部件。 - Sylvain BiehlerSelectFilter2.js
的末尾包含一个触发器,当你的类为 selectfilter 的选择加载完成时应该被调用。 - Sylvain Biehlerdjango_gulp
覆盖了collectstatic
和runserver
,你能否在不使用django_gulp
的情况下重试collectstatic --clear
? - Sylvain Biehlercollectstatic
有关,因为我的管理静态文件(存储在 S3 上)最后修改是几个月前,尽管今天运行了collectstatic --clear
(带或不带django_gulp
)。当我运行collectstatic --clear --verbosity 2
时,它显示正在跳过未修改的文件,而不是删除它们。仍在研究如何解决这个问题。 - wraasch
