问题描述
这是我的两个模型,我有一些问题,尝试在Django上用Haystack创建我的SearchIndex,我不知道该怎么做。
#Meta:存储有关教程(类别,标题)的元数据
class Meta(models
数据库[tutorial.meta]
mta_title = models.CharField(max_length = TUTORIAL_TITLE_MAX)
mta_views =模型。 PositiveIntegerField(default = 0)
#内容:存储教程文本内容
类内容(models.Model):
数据库[tutorial.contents]
tut_id = IdField()
cnt_body = BBCodeTextField()
现在我想将我的SearchIndex作为3个以下字段:mta_title,mta_views和cnt_body。以下是我目前的SearchIndex:
从haystack导入索引
从tutorial.models导入Meta作为TutorialMeta
从account.models导入配置文件作为UserProfile
类TutorialMetaIndex(indexes.SearchIndex,indexes.Indexable):
text = indexes.CharField(document = True,use_template = True)
title = indexes.CharField(model_attr ='mta_title')
views = indexes.CharField(model_attr ='mta_views')
#Haystack保留内部字段名称内部使用
cnt_body = indexes.CharField()
def get_model(self):
return TutorialMeta
def index_queryset(self,using = None):
当模型的整个索引被更新时使用。
return self.get_model()。objects.all()
def prepare_cnt_body(self,obj):
????
我看过这个问题,答案是创建一个prepare_cnt_body。但是我不知道该怎么回来。
谢谢大家。
谢谢Sectio Aurea,
但是这里是一个简单的准备功能的解决方案:
class TutorialIndex(indexes.SearchIndex,indexes.Indexable):
索引教程
text = indexes .CharField(document = True,use_template = True)
tut_id = indexes.IntegerField(model_attr ='tut_id')
cnt_body = indexes.CharField(model_attr ='cnt_body')
mta_title =索引.CharField()
mta_views = indexes.CharField()
def get_model(self):
返回当前模型
return TutorialContents
def get_updated_field(self):
返回更新日期跟踪字段
return cnt_date
def index_queryset(self,usin g =无):
当模型的整个索引被更新时使用。
return self.get_model()。objects.all()
def prepare(self,object):
准备搜索数据
self.prepared_data = super(TutorialIndex,self).prepare(object)
#检索教程metas并返回准备的数据
meta = get_tutorial_meta(id = object.tut_id)
self.prepared_data ['mta_title'] = meta.mta_title
self.prepared_data ['mta_views'] = meta.mta_views
return self.prepared_data
I have some problems by trying to create my SearchIndex with Haystack on Django and I don't know what to do.
Here are my two models:
# Meta: stores meta data about tutorials (category, title)
class Meta(models.Model):
"""
Database [tutorial.meta]
"""
mta_title = models.CharField(max_length=TUTORIAL_TITLE_MAX)
mta_views = models.PositiveIntegerField(default=0)
# Contents: stores the tutorial text content
class Contents(models.Model):
"""
Database [tutorial.contents]
"""
tut_id = IdField()
cnt_body = BBCodeTextField()
Now I want to base my SearchIndex on the 3 following fields: mta_title, mta_views and cnt_body. Here are my current SearchIndex:
from haystack import indexes
from tutorial.models import Meta as TutorialMeta
from account.models import Profile as UserProfile
class TutorialMetaIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
title = indexes.CharField(model_attr='mta_title')
views = indexes.CharField(model_attr='mta_views')
# Haystack reserves the content field names for internal use
cnt_body = indexes.CharField()
def get_model(self):
return TutorialMeta
def index_queryset(self, using=None):
"""Used when the entire index for model is updated."""
return self.get_model().objects.all()
def prepare_cnt_body(self, obj):
????
I've seen on this question, that the answer was to create a prepare_cnt_body. But I don't know what I should return.
Thank you everyone.
Thank you Sectio Aurea,
But here is my solution with a simple prepare function:
class TutorialIndex(indexes.SearchIndex, indexes.Indexable):
"""
Index the tutorials
"""
text = indexes.CharField(document=True, use_template=True)
tut_id = indexes.IntegerField(model_attr='tut_id')
cnt_body = indexes.CharField(model_attr='cnt_body')
mta_title = indexes.CharField()
mta_views = indexes.CharField()
def get_model(self):
"""
Return the current model
"""
return TutorialContents
def get_updated_field(self):
"""
Return the update date tracking field
"""
return "cnt_date"
def index_queryset(self, using=None):
"""
Used when the entire index for model is updated.
"""
return self.get_model().objects.all()
def prepare(self, object):
"""
Prepare the search data
"""
self.prepared_data = super(TutorialIndex, self).prepare(object)
# Retrieve the tutorial metas and return the prepared data
meta = get_tutorial_meta(id=object.tut_id)
self.prepared_data['mta_title'] = meta.mta_title
self.prepared_data['mta_views'] = meta.mta_views
return self.prepared_data
