鶺鴒默認搜索不與未英語領域

Question

我使用的是默認的後臺數據庫實現搜索功能在我的項目工作

class BlogPage(Page): 
    date = models.DateField("Post date") 
    intro = models.CharField(max_length=250) 
    body = StreamField([ 
     ('heading', blocks.CharBlock(classname="full title")), 
     ('paragraph', blocks.RichTextBlock()), 
     ('image', ImageChooserBlock()), 
     ('code', CodeBlock()), 
    ]) 
    tags = ClusterTaggableManager(through=BlogPageTag, blank=True) 

    search_fields = Page.search_fields + [ 
     index.SearchField('intro'), 
     index.SearchField('body'), 
    ] 
    ... 

和搜索工作以及只有bodyBlogPage模型中的字段是英文的，如果我嘗試在body字段中使用一些俄語單詞，那麼它不搜索任何東西。 我看着數據庫和我看到BlogPage具有body場這樣的：

[{"value": "\u0442\u0435\u0441\u0442\u043e\u0432\u044b\u0439", "id": "3343151a-edbc-4165-89f2-ce766922d68e", "type": "heading"}, {"value": "<p>\u0442\u0435\u0441\u0442\u0438\u043f\u0440</p>", "id": "22d3818d-8c69-4d72-967e-7c1f807e80b2", "type": "paragraph"}] 

那麼，問題是鶺鴒節省Streamfield領域的Unicode字符，如果我手動在phpMyAdmin改成這樣：

[{"value": "Тест", "id": "3343151a-edbc-4165-89f2-ce766922d68e", "type": "heading"}, {"value": "<p>Тестовый</p>", "id": "22d3818d-8c69-4d72-967e-7c1f807e80b2", "type": "paragraph"}] 

然後搜索開始工作，所以也許有人知道如何防止w from在unicode中保存Streamfield字段？

我恨這個解決辦法，但我決定只是爲了添加另一個領域search_body和search_intro，然後搜索使用它們：

class BlogPage(Page): 
    date = models.DateField("Post date") 
    intro = models.CharField(max_length=250) 
    body = StreamField([ 
     ('heading', blocks.CharBlock(classname="full title")), 
     ('paragraph', blocks.RichTextBlock()), 
     ('image', ImageChooserBlock()), 
     ('code', CodeBlock()), 
    ]) 
    search_intro = models.CharField(max_length=250) 
    search_body = models.CharField(max_length=50000) 
    tags = ClusterTaggableManager(through=BlogPageTag, blank=True) 

    def main_image(self): 
     gallery_item = self.gallery_images.first() 
     if gallery_item: 
      return gallery_item.image 
     else: 
      return None 

    def get_context(self, request): 
     context = super(BlogPage, self).get_context(request) 
     context['tags'] = get_all_tags() 
     context['page_url'] = urllib.parse.urljoin(BASE_URL, self.url) 
     return context 

    def save(self, *args, **kwargs): 
     if self.body.stream_data and isinstance(
       self.body.stream_data[0], tuple): 
      self.search_body = '' 
      for block in self.body.stream_data: 
       if len(block) >= 2: 
        self.search_body += str(block[1]) 
     self.search_intro = self.intro.lower() 
     self.search_body = self.search_body.lower() 
     return super().save(*args, **kwargs) 

    search_fields = Page.search_fields + [ 
     index.SearchField('search_intro'), 
     index.SearchField('search_body'), 
    ] 
    ... 

搜索/ views.py：

def search(request): 
    search_query = request.GET.get('query', None) 
    page = request.GET.get('page', 1) 

    # Search 
    if search_query: 
     search_results = BlogPage.objects.live().search(search_query.lower()) 
     query = Query.get(search_query) 
    ...

阿列克謝，謝謝！

但我得到保存方法的雙重電話。

而且我應該使用此代碼：

def save(self, *args, **kwargs): 
    search_body = '' 
    if self.blog_post_body.stream_data and isinstance(
      self.blog_post_body.stream_data[0], dict): 
     for block in self.blog_post_body.stream_data: 
      if block.get('type', '') in ('some_header', 'some_text'): 
       search_body += str(block['value']) 
    self.search_body = search_body 
    super(BlogPost, self).save(*args, **kwargs)
