问题描述
我有一个ModelForm,其中使用了FilteredSelectMultiple小部件.当我以创建的超级用户身份登录时,它的工作原理非常好.但是,当未登录时,我看不到窗体中的小部件,只能看到所有项目的列表(如多选).所以我的问题是:为什么FilteredSelectMultiple在登录时工作正常,而在退出时却不在?
I have a ModelForm in which I use the FilteredSelectMultiple widget. It works perfectly fine when I'm logged in as the superuser I have created. However, when not logged in, I cannot see the widget in the form, I only see the list of all items (like a multiple select). So my question is : why is FilteredSelectMultiple working perfectly fine when logged in, but is not there when logged out ?
我没有想到的任何地方都没有设置任何权限.
I haven't set any permission or anything like that anywhere that I can think of.
这是我的代码的一部分:
Here are parts of my code :
forms.py
from django.contrib.admin.widgets import FilteredSelectMultiple
class MyModelForm(forms.ModelForm):
my_field = forms.ModelMultipleChoiceField(queryset=Something.objects.all(), widget=FilteredSelectMultiple("Somethings", is_stacked=False), required=False)
class Media:
css = {
'all': (os.path.join(settings.BASE_DIR, '/static/admin/css/widgets.css'),),
}
js = ('/admin/jsi18n'),
class Meta:
model = MyModel
fields = ('some_field', 'some_other_field')
form.html
form.html
{% extends base.html %}
{% block head %}
{% load staticfiles %}
some stuff
{% endblock head %}
{% block content %}
<script type="text/javascript" src="{% url 'jsi18n' %}" > </script>
{{ form.media }}
<form enctype="multipart/form-data" method="POST">
{% csrf_token %}
{{ form.as_p }}
<button type="submit" class="save btn btn-default">Submit</button>
</form>
{% endblock content %}
urls.py
url(r'^admin/jsi18n/$',
'django.views.i18n.javascript_catalog',
name='jsi18n'
),
如果需要任何其他代码,请告诉我.(我使用Django 1.8和Python 2.7)
Tell me if you need any other code.(I use Django 1.8 and Python 2.7)
注销后加载页面时,控制台显示以下内容:
When loading the page when logged out, the consoles displays the following :
jsi18n:SyntaxError:期望的表达式,得到了<"
jsi18n : SyntaxError: expected expression, got '<'
SelectFilter2.js:ReferenceError:插值未定义
SelectFilter2.js : ReferenceError: interpolate is not defined
当我以超级用户身份登录时,这些消息都不会出现.
None of these messages appear when I am logged in as the superuser.
如答案中所建议,我尝试将媒体类更改为:
As suggested in the answers, I tried changing my media class to :
class Media:
# Nécessaire pour l'affichage de FilteredSelectMultiple
css = {
'all': (os.path.join(settings.BASE_DIR, '/static/admin/css/widgets.css'),),
}
extra = '' if settings.DEBUG else '.min'
js = ('/admin/jsi18n', 'jquery%s.js' % extra, 'jquery.init.js', 'core.js', 'SelectBox.js', 'SelectFilter2.js'),
哪个会导致AttributeError:
Which results in an AttributeError:
'tuple'对象没有属性'startswith'
'tuple' object has no attribute 'startswith'
[...]
异常位置:/path/to/virtualenv/local/lib/python2.7/site-packages/django/forms/widgets.py在absolute_path中,第74行
Exception Location: /path/to/virtualenv/local/lib/python2.7/site-packages/django/forms/widgets.py in absolute_path, line 74
我也尝试更改模板:
<script type="text/javascript" src="{% url 'jsi18n' %}" > </script>
<script type="text/javascript" src="{% static 'admin/js/jquery.min.js' %}"></script>
<script type="text/javascript" src="{% static 'admin/js/jquery.init.js' %}"></script>
<script type="text/javascript" src="{% static 'admin/js/core.js' %}"></script>
<script type="text/javascript" src="{% static 'admin/js/SelectBox.js' %}"></script>
<script type="text/javascript" src="{% static 'admin/js/SelectFilter2.js' %}"></script>
{{ form.media }}
没有产生任何错误,但是也没有改变我的问题:(
which didn't produce any error, but also didn't change anything to my problem :(
还有其他想法吗?
推荐答案
我不确定,但这可能是因为该网址位于admin auth下?
I am not fully sure, but it might be because of the url is under admin auth?
url(r'^admin/jsi18n/$',
'django.views.i18n.javascript_catalog',
name='jsi18n'
)
因此,当不以管理员身份登录时,无法访问脚本 jsi18n
,因为您需要通过身份验证才能访问脚本.
So when not logged in as admin, the script jsi18n
cannot be accessed because you need to be authenticated as admin to access the script.
将网址写为不受管理员管理:
Write the url to not be under admin:
url(r'^jsi18n/$',
'django.views.i18n.javascript_catalog',
name='jsi18n'
)
