Django Haystack索引来自同一模型的多个字段 [英] Django Haystack index on multiple fields from same model

问题描述

我正在尝试使用 django-haystack 将elasticsearch嵌入我的Django应用程序中。我正在尝试实施用户搜索。我的用户模型是这样的：

I am trying to embed elasticsearch in my Django app using django-haystack. I am trying to implement a user search. My user model is this:

class MyUser(AbstractBaseUser):
    username = models.CharField(max_length=255, unique=True)
    name = models.CharField(max_length=63, blank=True)
    email = models.EmailField(blank=True, unique=True)
    status = models.CharField(max_length=255, blank=True, null=True)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    joined = models.DateTimeField(auto_now_add=True, null=True)

现在，我要搜索名称和用户名字段。我创建了以下 search_indexes.py ：

Now, I want to search on name and username fields. I have created the following search_indexes.py:

class UserIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.EdgeNgramField(document=True, model_attr='name')
    username = indexes.CharField(model_attr='username')

    def get_model(self):
        return MyUser

    def get_updated_field(self):
        return "joined"

但是，当我执行搜索时，只会得到与 name 字段匹配的结果。我在这里做错了什么？还有其他方法吗？

However, when I perform a search, I only get the results matching the name field. What am I doing wrong here? Is there some other way to do this?

预先感谢。

推荐答案

django-haystack的工作方式， document = True 字段中的数据用于常规搜索，而其他字段则用于单个过滤。因此，在您的情况下，搜索将仅使用 name 字段。要解决此问题，您需要使用一个模板，该模板指定搜索中要使用的所有字段。首先，使用：

The way django-haystack works, the data inside the document=True field is used for a general search, and any other fields are used for individual filtering. So in your case, a search will only use the name field. To fix this, you'll need to use a template that specifies all the fields to be used in a search. First of all, use:

text = indexes.EdgeNgramField(document=True, use_template=True)

然后，您需要在模板目录中创建一个名为 search / indexes / myapp /的新模板myuser_text.txt 并将以下内容放入其中：

Then you’ll need to create a new template inside your template directory called search/indexes/myapp/myuser_text.txt and place the following inside:

{{ object.username }}
{{ object.name }}
