django - django haystack 突出显示模板标签问题

Question

有没有办法让 django-haystack 的{% highlight %}模板标签显示传入的完整变量，而不是在第一次匹配之前删除所有内容？

我这样使用它：

{% highlight thread.title with request.GET.q %}

Answer 1

我从未使用过 haystack，但从文档和源代码中快速查看，您可以制作自己的自定义荧光笔并告诉 haystack 使用它

from haystack.utils import Highlighter
from django.utils.html import strip_tags

class MyHighlighter(Highlighter):
    def highlight(self, text_block):
        self.text_block = strip_tags(text_block)
        highlight_locations = self.find_highlightable_words()
        start_offset, end_offset = self.find_window(highlight_locations)

        # this is my only edit here, but you'll have to experiment
        start_offset = 0
        return self.render_html(highlight_locations, start_offset, end_offset)

然后设置

HAYSTACK_CUSTOM_HIGHLIGHTER = 'path.to.your.highligher.MyHighlighter'

在你的 settings.py

@second 的答案有效，但是，如果您也不希望它切断字符串的结尾并且您的长度低于最大长度，您可以试试这个。仍在测试它，但它似乎工作：

class MyHighlighter(Highlighter):
    """
    Custom highlighter
    """
    def highlight(self, text_block):
        self.text_block = strip_tags(text_block)
        highlight_locations = self.find_highlightable_words()
        start_offset, end_offset = self.find_window(highlight_locations)
        text_len = len(self.text_block)

        if text_len <= self.max_length:
            start_offset = 0
        elif (text_len - 1 - start_offset) <= self.max_length:
            end_offset = text_len
            start_offset = end_offset - self.max_length

        if start_offset < 0:
            start_offset = 0
        return self.render_html(highlight_locations, start_offset, end_offset)
