Re: Django escapes a string partially

Hi,

You should wrap your  `data-content={{ v.error_msg }}` in quotes, like this: `data-content="{{ v.error_msg }}"`.

Otherwise you'll generate the template as `data-content='NoneType' object has not attribute "rfind"`, which is a valid HTML (data-content will have the string 'NoneType' and the node will have a bunch of tags that it doesn't know what to do with it, so they just sit there: "object", "has", "not", "attribute" and ""rfind"".)

Hi there!

I have a problem with escaping an error.

I have this unicode in python(2.7) which isn't escaped well in a span element:

u"'NoneType' object has no attribute 'rfind'"
The template is defined as follows:

<span id="status_{{ v.vid }}" {% if v.should_display_error_popover %}
      data-content={{ v.error_msg }} data-trigger="hover" rel="popover"
      data-original-title="Error Title" {% endif %}
      class="label extra-label label-pill label-{{ v.show_class | safe }}">
{{ v.get_human_status }}</span>

where v.error_msg is the string above. It should be noted that all other attributes works just fine

I wrapped the template in 
{% autoescape on %}
...template content...
{% endautoescape %}
Then I tried using the escape/force_escape tag on the problematic string:

{{ v.error_msg | force_escape }}

Nothing works, the output is only escaped once:

data-content="'NoneType'" object has not attribute 'rfind'
Which causes the resulting popover to show only with the message 'NoneType'.

What am I doing wrong? Why isn't the string properly escaped?

I'm using Djagno 1.5.11, but this syntax was defined well before version 1.5.11, so I don't think it's a version issue.

It's a minor issue but it's driving me mad.

Thanks,

Ron
