Get django object id based on model attribute

由 我们两清 提交于 2019-12-31 17:57:50
问题 I have a basic model named "Places" which has this view: def view_index(request, place_name): The user will access that view with a URL like this one: http://server.com/kansas "kansas" is a value stored in a field named "name" inside the model "Places". The problem is that I can't figure out how to obtain the object id based just on the object name. Is there a way to do this? 回答1: Like this: place = Places.objects.get(name='kansas') print place.id 回答2: Since you only want id , you should only

问题 I am working with DRF to build an API and I used a master class to do some validations to my class based views: class MasterClass(APIView): def dispatch(self, request, *args, ** response = super(FaveoAPIView, self).dispatch(request, *args, **kwargs) # I call super because I need access to request data. # <some validations here> # Return a JsonResponse with an error message if validations fails class MyView(MasteClass): def post(self, request, *args, **kwargs): # At this point request is:

“Reverse for … not found” - but there is?

问题 Ok, I've been banging my head against this for 30+ minutes, so here I am on stack overflow. I've got in a template: {% if user.is_authenticated %} <a href="{% url 'admin' %}"> Admin </a> {% endif %} And in urls.py: urlpatterns = [ path('admin', admin.site.urls, name = 'admin'), path('', views.index, name ='index'), ] Yet I still get: NoReverseMatch at / Reverse for 'admin' not found. 'admin' is not a valid view function or pattern name. Why is that? I even tested it out, and replaced admin

Redirect any urls to 404.html if not found in urls.py in django

由 家住魔仙堡 提交于 2019-12-30 18:06:53
问题 How can I redirect any kind of url patterns to a created page "404.html" page if it doesn't exist in the urls.py rather than being shown the error by django. 回答1: Make a view that'll render your created 404.html and set it as handler404 in urls.py. handler404 = 'app.views.404_view' Django will render debug view if debug is enabled. Else it'll render 404 page as specified in handler404 for all types of pages if it doesn't exist. Django documentation on Customizing error views. Check this

How Do I Use A Decimal Number In A Django URL Pattern?

由 ☆樱花仙子☆ 提交于 2019-12-30 08:22:28
问题 I'd like to use a number with a decimal point in a Django URL pattern but I'm not sure whether it's actually possible (I'm not a regex expert). Here's what I want to use for URLs: /item/value/0.01 /item/value/0.05 Those URLs would show items valued at $0.01 or $0.05. Sure, I could take the easy way out and pass the value in cents so it would be /item/value/1, but I'd like to receive the argument in my view as a decimal data type rather than as an integer (and I may have to deal with fractions

No module named backends.default.urls

由 江枫思渺然 提交于 2019-12-29 06:41:11
问题 So I've installed django-registration through easy_install. I'm following a quick start guide and I'm trying to setup my urlConf, however it says module named backends.defauls.urls is not found. What might be the problem ? import registration (r'^accounts/', include('registration.backends.default.urls')), 回答1: Is the registration module in your PYTHONPATH ? 回答2: (not my solution, but since it was hidden in a comment) You need to use use include('registration.urls') , instead of include(

问题 A solution: Found the following django snippet that seems to work fine (http://djangosnippets.org/snippets/2445/) from django.utils.functional import lazy from django.core.urlresolvers import reverse #Workaround for using reverse with success_url in class based generic views #because direct usage of it throws an exception. reverse_lazy = lambda name=None, *args : lazy(reverse, str)(name, args=args) Apparently, there is now a reverse_lazy function in django trunk. Update: This error has
