问题 Here's my custom filter: from django import template register = template.Library() @register.filter def replace(value, cherche, remplacement): return value.replace(cherche, remplacement) and here are the ways I tried using it in my template file that resulted in an error: {{ attr.name|replace:"_"," " }} {{ attr.name|replace:"_" " " }} {{ attr.name|replace:"_":" " }} {{ attr.name|replace:"cherche='_', remplacement=' '" }} I looked into django's docs and book but only found example using a

问题 I'd like to use a variable as an key in a dictionary in a Django template. I can't for the life of me figure out how to do it. If I have a product with a name or ID field, and ratings dictionary with indices of the product IDs, I'd like to be able to say: {% for product in product_list %} <h1>{{ ratings.product.id }}</h1> {% endfor %} In python this would be accomplished with a simple ratings[product.id] But I can't make it work in the templates. I've tried using with... no dice. Ideas? 回答1:

问题 How do I get the domain name of my current site from within a Django template? I've tried looking in the tag and filters but nothing there. 回答1: I think what you want is to have access to the request context, see RequestContext. 回答2: If you want the actual HTTP Host header, see Daniel Roseman's comment on @Phsiao's answer. The other alternative is if you're using the contrib.sites framework, you can set a canonical domain name for a Site in the database (mapping the request domain to a

问题 I am using Django 1.11 in my application. I've implemented the authentication using django-registration and created a profile model to store some user infos: class Profile(models.Model): ... user = models.OneToOneField(User) nick = models.CharField(max_length=50) level = models.PositiveIntegerField(null=True) avatar = models.CharField(max_length=500, null=True, blank=True) ... This model is being created/saved with signals: def create_user_profile(sender, instance, created, **kwargs): if

问题 I am using Django's Form Wizard package to create a 4-step form. I have created forms for each of the four steps. It's working fine. In my case I have created 4 separate templates and each step of the form wizard uses its own template. But each of these templates that I have created is substantially the same. Below is the code that is in each one. I cut and pasted this from elsewhere. It works, but I don't fully understand how or why: <form action="" method="post">{% csrf_token %} <table> {{

问题 I have the following code: settings.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'tectcom', 'USER': 'test', 'PASSWORD': '***146***', 'HOST': '', 'PORT': '', }, 'cdr': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'ast', 'USER': '123', 'PASSWORD': '654', 'HOST': '', 'PORT': '', } views.py def cdr_user(request): cursor = connections['cdr'].cursor() calls = cursor.execute('SELECT * FROM cdr') return render_to_response("cdr_user.html", {'result':calls }, context

问题 Originally I had just one app in my Django project, the templates consisted of an index.html a detail.html and a layout.html ... the index and detail files extended the layout. They all lived in the same directory ( [app1]/templates/[app1]/ ) and it could find all the files fine. Now I've got a second app, and I want to re-use the layout.html ... I decided to make a templates dir off the base of the django project, and put it in there. Here's what my directory structure looks like now:

问题 I know this question has been asked many times but even after resolving all the things I am still getting this error. My setup is as follow - settings.py """ Django settings for my_notebook project. Generated by 'django-admin startproject' using Django 1.8.3.

问题 I've started to create a form. Basically the form is a "test" of twenty words. The form consists of twenty text fields which I want to contain the definition of a word. The user would input the word. Once complete, the form should validate the data and mark what is correct and what isn't. I've done plenty of modelforms in django, but this one is different. All the data in this form has to be passed through as context. views.py def get_test(request, username='default'): template_name = 'main

问题 My for loop is not working and I'm not sure why. This is the loop: {% for i in range({{text|length}} + {{images|length}}) %} text and images are querysets I have passed to the template from the view. The error I am getting is: django.template.exceptions.TemplateSyntaxError: 'for' statements should use the format 'for x in y': for i in range({{text|length}} + {{images|length}}) This doesn't make sense to me, as it looks to me as if this does follow the format suggested by the error. 回答1: {%
