AttributeError：＆＃39; str＆＃39;对象没有属性＆＃39; resolve＆＃39;

Question

我正在尝试使用Django-recurrence模块。没有javascript_catalog在＆＃34;设置国际化＆＃34;根据指示：

# If you already have a js_info_dict dictionary, just add
# 'recurrence' to the existing 'packages' tuple.
js_info_dict = {
    'packages': ('recurrence', ),
}

# jsi18n can be anything you like here
urlpatterns = patterns(
    '',
    (r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict),
)

我在国际化之前看到的一切，如下：   - 重现的上半部分＆＃34; javascript-image＆＃34;没有显示。绿色文本部分（添加规则和添加日期）是唯一显示：

+Add rule+Add date

根据文档我期待的内容如下所示：

应用程序/ urls.py

js_info_dict = {
    'packages': ('recurrence', ),
}

urlpatterns = patterns(#'',
    (r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict),
    url(r'^room/$', CreateConfRoom_Sch.as_view(), name='CreateConfRoom_Sch'),

应用程序/ forms.py

class ScheduleConfRoom(ModelForm):
    class Meta:
        model = Schedule
        fields = ('name', 'room', 'message', 'recurrences',)
        widgets = {
            'message': Textarea(attrs={'cols': 25, 'rows': 6}),
        }

应用程序/ views.py

class CreateConfRoom_Sch(CreateView):
    form_class = ScheduleConfRoom
    template_name = "schedule.html"
    success_url = '/'

应用程序/ models.py

class Schedule(models.Model):
    name = models.CharField(max_length=30, default='Example')
    room = models.ForeignKey(Room) # default='Empty')
    message = models.CharField(max_length=918)
    recurrences = RecurrenceField()

schedule.html

<form method="POST" action="{% url 'upload_file' %}" >
    {% csrf_token %}
    {{ form.media }}
    {{ form.as_p }}
<button type="submit">Submit</button>
</form>

请帮忙!!!我做错了什么？当我在urls.py中有javascript_catalog时，主题中的错误显示。但是当我没有它时，只有＆＃34; +添加规则+添加日期＆＃34;示出。

Answer 1

回溯的locals信息显示它尝试使用以下字符串作为匹配模式：

pattern  'app.views'

该字符串取自urlpatterns文件中的app/urls.py序列，您只发布了 part 。

此外，您忘记了第一条规则的url功能：

(r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict),
# ^ no url

这使得它只是一个元组，然后第一个元素应该是一个正则表达式。添加url电话：

urlpatterns = patterns(#'',
    url(r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict),
    url(r'^room/$', CreateConfRoom_Sch.as_view(), name='CreateConfRoom_Sch'),

但是，您需要修复所有规则。
