Python 自定义视图不显示Django Haystack中使用弹性搜索的结果

我开始使用Django Haystack和Elasticsearch

好的，直到我开始按照中的简单示例创建自定义视图

搜索索引。py:

class ExperimentIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    owner = indexes.CharField(model_attr='owner')

    def get_model(self):
        return Experiment

    def index_queryset(self, using=None):
        return self.get_model().lastversion_objects.all()

url(r'^search/?$', NepSearchView.as_view(), name='search_view')

url(r'^search/', include('haystack.urls'))

{# ... #}
{% for result in page.object_list %}
{% if result.model_name == 'experiment' %}
{% include 'search/experiments.html' %}
{% endif %}
{% if result.model_name == 'study' %}
{% include 'search/studies.html' %}
{% endif %}
{% if result.model_name == 'group' %}
{% include 'search/groups.html' %}
{% endif %}
{% if result.model_name == 'experimentalprotocol' %}
{% include 'search/experimental_protocol.html' %}
{% endif %}
{# ... #}

url.py:

class ExperimentIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    owner = indexes.CharField(model_attr='owner')

    def get_model(self):
        return Experiment

    def index_queryset(self, using=None):
        return self.get_model().lastversion_objects.all()

url(r'^search/?$', NepSearchView.as_view(), name='search_view')

url(r'^search/', include('haystack.urls'))

{# ... #}
{% for result in page.object_list %}
{% if result.model_name == 'experiment' %}
{% include 'search/experiments.html' %}
{% endif %}
{% if result.model_name == 'study' %}
{% include 'search/studies.html' %}
{% endif %}
{% if result.model_name == 'group' %}
{% include 'search/groups.html' %}
{% endif %}
{% if result.model_name == 'experimentalprotocol' %}
{% include 'search/experimental_protocol.html' %}
{% endif %}
{# ... #}

url.py之前（无自定义视图）：

class ExperimentIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    owner = indexes.CharField(model_attr='owner')

    def get_model(self):
        return Experiment

    def index_queryset(self, using=None):
        return self.get_model().lastversion_objects.all()

url(r'^search/?$', NepSearchView.as_view(), name='search_view')

url(r'^search/', include('haystack.urls'))

{# ... #}
{% for result in page.object_list %}
{% if result.model_name == 'experiment' %}
{% include 'search/experiments.html' %}
{% endif %}
{% if result.model_name == 'study' %}
{% include 'search/studies.html' %}
{% endif %}
{% if result.model_name == 'group' %}
{% include 'search/groups.html' %}
{% endif %}
{% if result.model_name == 'experimentalprotocol' %}
{% include 'search/experimental_protocol.html' %}
{% endif %}
{# ... #}

视图.py

class NepSearchView(SearchView):

    def get_queryset(self):
        queryset = super(NepSearchView, self).get_queryset()
        if not self.request.user.is_authenticated and \
                self.request.user.groups.filter(name='trustees').exists():
            return queryset  # (with some filter)
        else:
            return queryset

search.html:

class ExperimentIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    owner = indexes.CharField(model_attr='owner')

    def get_model(self):
        return Experiment

    def index_queryset(self, using=None):
        return self.get_model().lastversion_objects.all()

url(r'^search/?$', NepSearchView.as_view(), name='search_view')

url(r'^search/', include('haystack.urls'))

{# ... #}
{% for result in page.object_list %}
{% if result.model_name == 'experiment' %}
{% include 'search/experiments.html' %}
{% endif %}
{% if result.model_name == 'study' %}
{% include 'search/studies.html' %}
{% endif %}
{% if result.model_name == 'group' %}
{% include 'search/groups.html' %}
{% endif %}
{% if result.model_name == 'experimentalprotocol' %}
{% include 'search/experimental_protocol.html' %}
{% endif %}
{# ... #}

事实上，当使用默认Haystack

SearchView

时，我找到了正确的匹配项，而在引入

NepSearchView

时，

页面。对象列表

为空，我在模板中找不到任何结果。

---

我已经运行了

manage.py rebuild\u index

，在web上进行了大量搜索，但找不到任何可以解释我所缺少内容的内容。

查询集的page.object\u列表变量名似乎不存在。 请尝试不带“页面”前缀的对象列表

而不是

{% for result in page.object_list %}

使用

或者，您也可以在视图中添加如下内容，以提供自定义变量名

context_object_name = 'haystack_objects'

并在模板中使用它

{% for result in haystack_objects %}

---

很晚了，但我想我会问：你是如何着手诊断这个问题的？我挣扎了几个小时，精确地匹配了文档中的教程，尽管仍然使用默认模板

page.object\u list

。我很想知道今后如何避免类似的头痛。
