django-carton cart with two product models
I am using django-catron and I wonder if I can associate two of models as products for my cart? If yes, how? I have two models: Hall and Caterer and I want them to be my products, which I can insert in my cart (and basically perform any other provided operations). CART_PRODUCT_MODEL = ['marriage_halls.models.Hall', 'marriage_halls.models.Caterer'] I tried something like this setting but it gives me error: no attribute 'rsplit' -

How do I update my Django url for version 1.10?
So I'm going through PluralSight's 'Django Fundamentals' and it's based on an older version of Django. As I'm writing this now I am using Django 1.10 which I believe is the up to date version. As I'm following the video I'm creating a database for a fictional school. This is my url pattern based on the one on the Pluralsight tutorial: from django.conf.urls import url from django.contrib import admin from school.views import home urlpatterns += patterns( 'django.contrib.auth.views', url(r'^login/$', 'login', {'template_name': 'login.html'}, name = 'school_login'), url(r'^logout/$', 'logout', {'next_page': 'school_home'}, name = 'school_logout'), ) Now how to I update it so that it works with Django 1.10? -

Parsing XML into a dictionary of lists Python/Django
I'm having a little issue with parsing an xml with python. I'm trying to get my dictionary to look like the following listDict = [{'name':'Sales','id':'1','position':'1','order_by_type':'True','order_by_asc':'True;}, {'name':'Information','id':'2','position':'1','order_by_type':'True','order_by_asc':'True;}] I'm thinking my loop after pulling data from the xml string is wrong. xml_data = ElementTree.fromstring(self.data) # Lets grab all the base cats info and add them to a dict containing a list base_cats = xml_data.findall('./BaseCategory/Name') base_cats_id = xml_data.findall('./BaseCategory/base_id') base_postion = xml_data.findall('./BaseCategory/position') base_order_by_type = xml_data.findall('./BaseCategory/order_by_type') base_order_by_asc = xml_data.findall('./BaseCategory/order_by_asc') # store all information into lists base_cat = [t.text for t in base_cats] base_id = [t.text for t in base_cats_id] base_p = [t.text for t in base_postion] base_obt = [t.text for t in base_order_by_type] base_asc = [t.text for t in base_order_by_asc] base_dict = defaultdict(list) # lets put everything in the list into a dictionary for base in range(len(base_cat)): # for each base in base_cat loop base_dict[base].append(base_cat[base]) base_dict[base].append(base_id[base]) base_dict[base].append(base_p[base]) base_dict[base].append(base_obt[base]) base_dict[base].append(base_asc[base]) This produces the following. instance = {0: ['Sales 2', '1', '10', 'True', 'True'], 1: ['Information 2', '2', '20', 'True', 'True'], 2: ['Listing 2', '3', '30', 'True', 'True'], 3: ['Information', '4', '40', 'True', 'True'], 4: ['Land', '5', '50', 'True', 'True'], 5: ['&', '6', '60', 'True', 'True'], 6: ['Tax', '7', '70', 'True', 'True'], 7: ['Construction', '9', '90', 'True', … -
With Django CKeditor, how to load different toolbars on different fields?
I'm using the django CKeditor plugin. My config is as follows: CKEDITOR_CONFIGS = { 'default': { 'skin': 'moono', #'office2013' 'toolbar': 'Custom', #selects from below 'toolbar_Custom': [ ['Bold', 'Italic', 'Underline', 'Strike', 'Subscript'] ], 'toolbar_simple': { 'skin': 'moono', 'toolbar': 'Custom', 'toolbar_Custom': [ ['Bold', 'Italic', 'Underline'], ['NumberedList', 'BulletedList'], ], }, 'toolbar_basic': { 'toolbar': 'Basic' }, 'toolbar_full': { 'toolbar': 'full', }, } How to load these different toolbars on different fields? I hope there's an option like: directions_car = RichTextField("Directions by car", max_length=1000, blank=False, default="", uses="toolbar_Custom") -
Need to add primary and foreign keys to a column postgresql 9.3.2 using phpPgAdmin
My apologies if this is a question with an obvious answer- but I am recovering from the lingering effects of a car accident, and still working to regain some of the things I used to know. I've got a django application that uses a PostgreSQL database indexed by Xapian, and while I was in recovery, one of the columns in an empty table somehow got dropped. When I returned to work, I found that running ./manage.py rebuild_index failed because it was expecting the missing column and couldn't find it. To make the repair a little easier (I hope) I installed phpPgAdmin. There's no problem connecting to the database, and I was able to add the missing column through the interface. After that, the Xapian index was able to rebuild with no errors, but the table is still not functioning correctly. I had hoped that the application would apply the primary and foreign keys once tested, but I am still seeing this in the phpPgAdmin interface: (Screen snip of the columns involved) As shown in the link, the key icons in the top column are not replicated in the bottom column. I'm fairly certain I can add them with ALTER TABLE, … -
Django IntegrityError with DateTimeField
i have field in object: view_time = ArrayField( models.DateTimeField(auto_now_add=True)) but i get error: django.db.utils.IntegrityError: null value in column "view_time"violates not-null constraint DETAIL: Failing row contains (18, 0, null, null, null). error rise when i try to create new object, and add value: recent_views = UserRecentViews.objects.create() recent_views.add_view(product.article) i use django 1.8.8 and Python 3.5.2 i reset database fiew times but it doesn`t help, db is Postgres. I think problem in object creation? but why django can not create object with current datetime? auto_now_add=True was added for this. My question is how add autogenerated datetime field with django? -
Django - int() argument must be a string or a number, not 'Patients'
for the context : I have 2 tables, user (which is a copy of the auth_user table, with small modifications) and patients I want to make a DetailView without passing the pk argument, so my user don't have access to his id The primary key of Patients is a the foreign key "patients" in User, so I can link these two tables My Patients model: class Patients(models.Model): id = models.IntegerField(primary_key=True) # And other keys not importants My views.py: class ProfilView(LoginRequiredMixin, generic.DetailView): login_url = '/membres/login/' #model = Patients template_name = 'membres/profil.html' def get_object(self): user_loggin = get_object_or_404(User, pk=self.request.user.id) return Patients.objects.get(pk=user_loggin.patients) I think I return something wrong, but after searching on internet a lot, I don't understand how i'm suppose to make this working, thanks for your help. -
DRF - using view classes for custom URL design?
I would like to realise the following URL design (based on githubs' REST api) for a User model in django rest framework: # get authenticated user (the currently logged in user): # # GET user/ # # update authenticated user: # # PATCH user/ # # get single user (will only return instructors) # # GET user/:username # # get all users (will only return instructors) # # GET users/ Given a User model I have the following standard serializer: class UserSerializer(serializers.ModelSerializer): class Meta: model = models.MyUser fields = '__all__' I can implement the url routes using function based views for each URL, but DRF offers many class-based views and routers and I was wondering if there was a more concise way of implementing it? -
Errors from back-end are not coming on front
I'm using django on server and angular 2 on front. When server response error I have an empty response. When I do this request through curl I have an error that server send me. P.S. I'm using CORS. Nginx config server { listen 80; server_name server_name location / { proxy_pass *in docker container* } location ~ /rest { add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'PROPFIND, PROPPATCH, COPY, MOVE, DELETE, MKCOL, LOCK, UNLOCK, PUT, GETLIB, VERSION-CONTROL, CHECKIN, CHECKOUT, UNCHECKOUT, REPORT, UPDATE, CANCELUPLOAD, HEAD, OPTIONS, GET, POST'; add_header 'Access-Control-Allow-Headers' 'Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers, X-XSRF-TOKEN'; add_header 'Access-Control-Allow-Credentials' 'true'; if ($request_method = 'OPTIONS') { return 200; } proxy_pass *in docker container* } } -
Different versioning scheme for Django REST Framework Browsable API
I have a requirement for an API that no default version is allowed. All clients are required to explicitly specify the version of any resource. I have achieved this with the following configuration: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'oauth2_provider.ext.rest_framework.OAuth2Authentication', 'rest_framework.authentication.SessionAuthentication', ), 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), 'DEFAULT_VERSIONING_CLASS': 'rest_framework.versioning.AcceptHeaderVersioning', 'ALLOWED_VERSIONS': ['2.0'], 'DEFAULT_RENDERER_CLASSES': ( 'api.renderers.CustomJSONRenderer', 'rest_framework.renderers.BrowsableAPIRenderer', ), } This works great, however I just lost the ability to use the browsable API renderer: HTTP 406 Not Acceptable Allow: GET Content-Type: application/vnd.acme+json Vary: Accept { "detail": "Invalid version in \"Accept\" header." } I would like to specify that if a request is done to the browsable API, the default version should be 2.0. The reasoning is that when experimenting with the browsable API, the default should be the latest version, however when consuming the API programmatically a user should not be exposed to breaking changes because they neglected to specify their version. How can I make my API require a version but allow the browsable API to be exempt? -
Django 1.10 migration support for apps in subdirectories
I put a simple project together with two apps in an apps directory: myproject/ | manage.py |-- myproject/ | | __init__.py | | settings.py | | urls.py | | wsgi.py |-- apps/ | | __init__.py | | app1/ # with models.py and views.py | | app2/ # with models.py and views.py I've updated the INSTALLED_APPS setting to include apps.app1 and apps.app2. The apps.app1 is the only app with models: class Thing(models.Model): stuff = models.CharField(max_length=255) If I run ./manage.py check and it comes back fine. However, if I try to run ./manage.py makemigrations apps.app1 I get the following error: App 'apps.app1' could not be found. Is it in INSTALLED_APPS? But apps.app1 is clearly in the settings file, here is the settings file (copy and pasted): INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'apps.app1', 'apps.app2', ] Other things I've read seem to indicate that is should be possible to have Django apps in subdirectories. Is this not actually possible? OR, if it is possible, what am I doing wrong? -

Django get full url including an odd query string
I need to get a url from views.py of the structure: localhost:8000/path/name#stuff=2&otherstuff=3 Notice that instead of the usual '?' char to start the query string there is a '#'. In Django, I've tried: stuff = request.GET.get('stuff') This returns None, I'm guessing because of the url structure. I've also tried to get url info using: url = request.resolver_match.url_name and request.get_full_path() which returns only: /path/name/ Does anyone know of a way to get this full url in views? -

Django: Allow only logged in users to download files uploaded by them
Thanks to SO, could manage to progress. You may refer these 2 questions asked for the code to upload file and download files. Django: Adding files to a form gives multiple argument error Django: Downloading uploaded files Now the major issue I have is how to prevent file download by unauthorized users.
