django blocktrans and i18n in templates
django, internationalization, templates, translation
Solution
I'm only just getting started with Django internationalization, but I think you're misunderstanding how the `{% blocktrans %}` tag handles placeholders.
The point of `blocktrans` is to allow the text around the placeholders to be translated. It won't translate anything inside `{{...}}`.
If you look at the generated `.po` file, you'll see that the following template code:
{% blocktrans %}This is my variable: {{variable}}{% endblocktrans %}
Will get converted into something like the following:
msgid:"This is my variable: %s"
I don't think you can translate a variable within a blocktrans tag. You can probably do constant strings with `{% blocktrans with _("string") as x %}{{x}}{% endblocktrans %}` but I can't think why you'd want to.
You'll have to do what you want in your view or model code I think.
Problem
I have an i18n problem in django: This works fine : ``` {% trans cat.name %} ``` `cat.name` will be translated But this doesn't work: ``` {% blocktrans with cat.name|slugify as cat_slug %}{{ cat_slug }}{% endblocktrans %} ``` `cat.name` is not translated If I change the filter : ``` {% blocktrans with cat.name|capfirst as cat_slug %}{{ cat_slug }}{% endblocktrans %} ``` I can see that the filter is working, but there is no translation...
