翻译django模板中的动态内容

Question

I have a html template rendered by a view in django. And the template has some dynamic values that the view sends.

Example::

{{ text_to_be_translated.brand_name}}

The above 'text_to_be_translated.brand_name' is a dictionary with thousands of keys like brand_name, which can hold many values like 'my brand', 'your brand' etc

I am not able to get the above dynamic text translated.

I tried to manually put msgids for the texts in the po file

msgid "my brand"
msgstr "カードインフォメーション"

But it doesn't get translated.

What am I doing wrong, please help.

Answer 1

Just writing so that somebody may benefit.

I solved the problem by writing a template filter and force translating the text in the template using 'django with tag'

In template.html

{% with card_details_trans=registration_card_details.card_details|template_trans %}
    {% trans card_details_trans %}
{% endwith %}

In Template Tag

@register.filter(name='template_trans')
def template_trans(text):
    try:
        return ugettext(text)
    except:
        return text

Logic

1. Django doesn't know that contents of a dynamic variable needs to be translated.
2. The with tag calculates the translated value from the applied filter and gives the translated output.

Hope it helps. Cheers!!!
