我有一個自定義過濾器,它接受一個字符串並將其轉換爲我正在使用的工具提示庫的相應屬性。它與OpenTip協同工作,但我轉而使用Bootstrap中的工具提示庫。Django模板過濾器轉義
這裏是我的過濾器:
from django import template
from django.utils.html import conditional_escape
from django.utils.safestring import mark_safe
register = template.Library()
@register.filter(needs_autoescape=False, is_safe=True)
def tooltip(value, autoescape=False):
"""
Filter to turn some text into the tag that the tooltip library uses -
Written as a filter so we can switch from one tooltip library to
another
"""
if autoescape:
esc = conditional_escape
else:
esc = lambda x: x
if value is not None and len(value) > 0:
retval = 'data-toggle="tooltip" data-html="true" ' +\
'rel="tooltip" title="%s"' % esc(value)
return mark_safe(retval)
else:
return ''
這裏的地方我用它在一個模板:
<form id="filter" name="filter" method="post"
class="form-inline">
{% csrf_token %}
<label for="filterText">Filter Query:</label>
<input type="text" id="current_filter" name="current_filter" value="{{current_filter}}" placeholder="Filter" class="span8"/>
<i class="icon-question-sign"
{{"Filters -<br>requester: [[first] [last]]|[windows_id]<br>client: [[first] [last]]|[windows_id]<br>approver: [[first] [last]]|[windows_id]<br>worker: [[first] [last]]|[windows_id]<br>ticket: [id]<br>status: [open]|[closed]|[hold]<br>type: [termination]|[extension]|[access]|[password]|baskets]<br>item: [name for category/item/attribute inventory]<br>since: [mm/dd/yyyy]|[yyyy-mm-dd]<br>before: [mm/dd/yyyy]|[yyyy-mm-dd]<br>All searchs are AND with comma delimiting"|tooltip}}></i>
<input type="submit" name="btnSubmit" class="btn" value="Filter"/>
<input id="filter_reset" type="button" name="filter_reset" class="btn" value="Clear existing filters"/>
</form>
{% endif %}
但提示不處理HTML,當我去到螢火蟲並剪切和粘貼的HTML,它看起來像東西是逃避它,儘管事實上,我標記它mark_safe:
<form class="form-inline" method="post" name="filter" id="filter">
<input type="hidden" value="dpuAc9GNUQtvGG5wYzrWsG2Vpu5i7PWJ" name="csrfmiddlewaretoken">
<label for="filterText">Filter Query:</label>
<input type="text" class="span8" placeholder="Filter" value="" name="current_filter" id="current_filter">
<i title="Filters -<br>requester: [[first] [last]]|[windows_id]<br>client: [[first] [last]]|[windows_id]<br>approver: [[first] [last]]|[windows_id]<br>worker: [[first] [last]]|[windows_id]<br>ticket: [id]<br>status: [open]|[closed]|[hold]<br>type: [termination]|[extension]|[access]|[password]|baskets]<br>item: [name for category/item/attribute inventory]<br>since: [mm/dd/yyyy]|[yyyy-mm-dd]<br>before: [mm/dd/yyyy]|[yyyy-mm-dd]<br>All searchs are AND with comma delimiting" rel="tooltip" data-html="true" data-toggle="tooltip" class="icon-question-sign">
</i>
<input type="submit" value="Filter" class="btn" name="btnSubmit">
<input type="button" value="Clear existing filters" class="btn" name="filter_reset" id="filter_reset">
</form>
如何獲取該過濾器文本中的html到頁面中而不被轉義?
tooltip的文檔說它*可以*使用html。其他人有一個演示它的小提琴:http://jsfiddle.net/44khF/200/所以這是django搞砸了。 –
你說得對,它可以用'data-html =「true」'包含html。然後,你所要做的就是將html內容標記爲安全,並且不會被django轉義。 –
