Django - use custom template loader on a per-request basis?

阅读更多关于 Django - use custom template loader on a per-request basis?

问题 Is there a lower-level way to provide the list of loaders when rendering a template, as opposed to always having Django use the setting? I'd like to use a custom template loader instance for only a few views (I have my reasons). 回答1: It looks like you'll have to write some code of your own to do it. Let's take a look at the normal code path for loading templates, if you use, say, render_to_response , where the relevant part of the source is: return HttpResponse(loader.render_to_string(*args,

阅读更多关于 update value of a variable inside a template - django

问题 I have seen enough number of examples that allow me to declare a new variable inside a template and set its value. But what I want to do is to update the value of a particular variable inside the template. For example I have a datetime field for an object and I want to add timezone according to the request.user from the template. So I will create a template filter like {% add_timezone object.created %} and what it will do is that it will add timezone to object.created and after that whenever

问题 When I add {% extends "X.html" %} to my child templates (the parent being "base.html"), only the parent template is loaded. When I take it away, the child template is loaded. I have another app where I have a seemingly identical inheritance structure, so I'm stumped. Here is "base.html": <!DOCTYPE html> {% load staticfiles %} <html> <head> {% block js %} <script src="{{ STATIC_URL }}js/jquery.1.12.4.min.js"></script> <script src="{{ STATIC_URL }}js/p5.js" {% endblock %} <title>myapp</title> <

template url reversal escaping surt arguments

阅读更多关于 template url reversal escaping surt arguments

问题 I'm having an issue where the template url reversal is escaping colon and parenthetical characters. I want these characters to remain unescaped in the anchor tag's href attribute. It used to behave this way when I was in django 1.3, but upgrading to 1.6, I notice that this does not behave as I want. What I have: surt = 'http://(gov/' browse_domain = 'gov' ... in template ... <a href="{% url 'nomination.views.url_surt' project.project_slug surt %}">{{ browse_domain }}</a> This yields: <a href=

阅读更多关于 Official advice for printing all Django form errors in a template not working…or not understood

问题 I can't figure out how to print all form error messages in a Django (1.7) template, despite following the advice in the official docs and elsewhere. I have an account user/pass admin/admin. I've intentionally changed the minimum allowable username length in the LoginForm to 6, in an effort to get a "bad length" error, instead of a "bad user/pass combo" error (full form/view code at the bottom). According to the official docs, the following should print all error messages: {% if form.errors %}
