问题 Is it possible to override an existing Django Template Tag or is it necessary to customize the template file and create a new Template Tag? 回答1: Yes. As django is basically a python library (as with everything in python) you can over-write anything you'd like. It's not clear exactly what you'd like to do but it really is pretty easy to roll-your-own templatetag, the docs are pretty clear: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/#writing-custom-template-tags This is

问题 I'm trying to filter a model with get_queryset() and it seems to work in the view but not in the template. My view : class FolderCreate(CreateView): fields = ['name', 'parent'] template_name = 'Form/folder_create.html' def get_queryset(self): folders = Folder.objects.filter(owner=self.request.user) print folders # ==> return [<Folder: Folder>, <Folder: Another folder>] return folders def form_valid(self, form): self.object = form.save(commit=False) self.object.owner = self.request.user return

问题 I'm doing something like: {% extends 'base.html' %} {% url myapp.views.dashboard object as object_url %} {% block sidebar %} ... {{ object_url }} ... {% endblock %} {% block content %} ... {{ object_url }} ... {% endblock %} Django documentation says url templatetag can define a variable in context, but I don't get any value for object_url in the following blocks. If I put the url templatetag at the beginning of each block, it works, but I don't want to "repeat myself". Anyone knows a better

问题 I am using built-in django login and logout. In my Project/urls.py i have added url's for both login and logout. from django.conf.urls import include, url from account import views from django.contrib.auth import views as auth_views from django.contrib import admin urlpatterns = [ url(r'^admin/', include(admin.site.urls)), url(r'^$',views.index,name='Index'), url(r'^accounts/login/$',auth_views.login,name='login'), url(r'^accounts/logout/$',auth_views.logout,name='logout'), url(r'^accounts

问题 In my core.html I have a block labeled javascript. It would be great if I can append more lines to this block without overwriting everything in it. 回答1: {% block javascript %} {{ block.super }} ... more content ... {% endblock %} See: Django documentation - Template inheritance 回答2: Using block.super works fine when extending a template but not as well when including one, ie: {% extends "base.html" %} vs. {% include "partial.html" %} Say you want to include a template in the middle of your

问题 I know I can get the current date as a str in a Django template (using the template tag now), like this: {% now "Y-m-d" as today_str %} <p>{{ today_str }}</p> But I cannot use that for comparissons: {% now "Y-m-d" as today_str %} {% for elem in object_list %} {% if elem.date < today_str %} {# WRONG: this compares 'date' and 'str' #} <p>{{ elem.pk }} before today</p> {# do some other rendering #} {% endif %} {% endfor %} Possible solutions: I know I can pass a context variable to the template,

问题 t = Template(" my name is {{ my_name }}") c = Context({ "my_name": patient.name }) //(like patient.age,patient.height.......... i want to display 8 fields of form in my datatable.) d = t.render(c) I want to display the template value in datatable. Here is my HTML code, where I'm trying but could getting exactly.

问题 I'm trying to pass query parameters via my view into a link, but it escapes me on how to actually achieve this in a good way. My template is as following: <a class="link-button" href="{% url 'videos:index' %}?tag={{ tag }}&page={{ next }}">Next</a> This returns what I want: http://127.0.0.1:8000/videos/?tag=1&page=2 While this works, it's quite fragile, does not handle None values and there must be a better way of doing this. I tried to pass this via the url template tag but it did not seem

问题 My views.py: @login_required def some_views(request): if request.method == 'POST': form = AddressCreateFrom(request.POST) if form.is_valid(): name = form.cleaned_data['Address'] ip_value = form.cleaned_data['value'] user_list = get_username(name) address_create = form.save() extra_context = { 'user_list': user_list } return redirect_to(request, url=address_create.get_absolute_url()) else: form = AddressCreateFrom() extra_context = { 'form':AddressCreateFrom(initial={'user': request.user.pk})

问题 I'm trying to check if email id entered by user is existing in the database table, if existing - I would like to route to 'prof.html' template otherwise just show a message in the login.html template. Both the conditions are working fine. However, the problem is when I use redirect() or render_to_response() - the destination template elements like div, input etc., are being changed automatically (prof.html in this case) ? Can we also send the context information to destination template ?
