Great tip!
thanks for this hint, I decided to (mis-)use extra_tags for this
purpose!
I have now implemented the following:
try:
# build a safe message
raise InvalidUserException(message=mark_safe('some <b>safe</b>
message'))
expect Exception e:
# test if content is safe, if so: flag message as safe
extra_tags = None
if isinstance(e.message, SafeData):
extra_tags = 'safe'
messages.error(request, e.message, extra_tags)
And now I can show the message in my template, with the help of an
extra template_tag
{% if messages %}
<ul class="messages">
{% for message in messages %}
<li{% if message.tags %} class="{{ message.tags }}"{%
endif %}>{{ message|test_safe_tag }}</li>
{% endfor %}
</ul>
{% endif %}
Where test_safe_tag is defined as:
@register.filter
def test_safe_tag(message):
"""test if the message contains safe in the extra_tag"""
if message.extra_tags == "safe":
message.message = mark_safe(message.message)
return message
it's not perfect: it generates an extra class in my html (safe), and I
need to perform these extra steps (of performing the testing if it is
safe, to set the extra flag, and when presenting I have to test for
this flag again as well), but at least it is allowed when marked safe!
