django-templates

I recently started making web apps, and while I make some stuff that works, I'm not sure of the best practices. Up to now, I've mostly used the templating systems of Django, web.py and PHP. But now that I'm using jQuery and nice ajaxy magic to get data from the server without refreshing the client, I'm seeing the advantages of building the HTML directly in javascript (so I can just send a small json object to the client and have him figure out what to change and how). So now I have some bits that are rendered with templates, and some that are built in javascript, and even one horrid case where

I have one form : class FormLogin(forms.Form): email = forms.EmailField(max_length=150) name = forms.CharField(max_length=20) How can I put just email field in my template ? I tried this : {{ form.fields.email }} But it returns <django.forms.fields.CharField object at 0x00000000043BCEB8> . You can just use: {{ form.email }} You don't need to use fields . Use: {{ form.email }} 来源： https://stackoverflow.com/questions/13521634/get-only-one-field-from-django-forms-in-template

Is it possible to check in template that some url match any pattern from urls? This is something you'd normally want to do in a views.py file with the reverse () helper for named URLs with known args or resolve () for paths. If you do need this functionality in a template specifically, here is a hacky solution: @register.simple_tag def urlpath_exists(name): """Returns True for successful resolves()'s.""" try: return bool(resolve(path)) except Resolver404: return False Note : this doesn't guarantee that the URL is valid, just that there was a pattern match. You can use the "as" form of the url

I am using Nitrous for playing with the Django framework. In tutorial 2 is shown how to change the base_site.html template. I've added in the TEMPLATE_DIRS = ( ) a new line: 'home/action/workspace/mysite/templates', And in base_site.html I changed the site name title of Django Administration into Administration: {% trans 'Administration' %} But I still see no changes on the website. I've tried different TEMPLATE_DIRS like: '~/workspace/mysite/templates', 'home/action/workspace/mysite/', 'home/action/workspace/mysite/templates/', And restarting the server. But I am doing something wrong. Note

In a Django template, I'd like to add CSS classes to a DIV based on certain "conditions", for example: <div class="pkg-buildinfo {% if v.release.version == pkg.b.release.version %}active{% else %}inactive{% endif %} {% if v.release.version == project.latest.version %}latest{% else %}notlatest{% endif %}"> ( note that v is a loop variable; the whole thing is inside a for loop) The above adds CSS classes "active" or "inactive" and "latest" or "notlatest" based on two conditions. This is however hard to read and verbose. I discovered that the with statement does not support assigning the value of

Background: - Am using ajax to get a entity called as "foo_posts". In this post am using facebook share and like button {% for post in foo_posts %} <div class="foo"> {{ post }} <div class="fb-like" data-send="true" data-width="450" data-href="http://foo/foo/detail/{{ foo.id }}/" data-show-faces="true"></div> </div> {% endfor %} Now these posts are being populated using Ajax. Problem: - The facebook like and share gets initialized by $(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect

I upgraded to a fresh install of Django 1.8 and began using Jinja2 as it said that it was supported now and Jinja2 has some features I could use in my project. After finishing adapting the templates for my app to Jinja2 and taking advantage of the new features now available, I discovered that the contrib app Admin no longer works. "TemplateDoesNotExist at /admin/login/" So it turns out that contrib app Admin only has templates made for DjangoTemplates and not for Jinja2. I did the naive thing first and made a symlink in [...]/site-packages/django/contrib/admin from templates to jinja2 but the
