Django queryset with multiple m2m fields
I have these models: class Doctor(models.Model): coopsort = ManyToManyField('Cooperation', related_name='coopsort') name = models.CharField(...) class Cooperation(models.Model): doctor = models.ManyToManyField(Doctor, blank=True, verbose_name=u"Doc") How can I query all Cooperations for a given doctor using the coopsort m2m field? Cooperation.objects.filter... <pls advise here> -
django issues between forms and models
i am a beginner with Django. I want to ask how can i access a variable in forms.py to print out for the user. I know that models.py create the database for the user. The variable that i want to print it is a checkbox multiple choice field. I need to print the value of the multiplechoice in a table.The image is here Forms.py: market = forms.MultipleChoiceField(required=False,widget=CheckboxSelectMultiple, choices=MARKET_CHOICES) sector = forms.MultipleChoiceField(required=False,widget=CheckboxSelectMultiple, choices= MEDIA_CHOICES) I want to print in the html template these two variables Models.py: class Parameters(models.Model): user = models.ForeignKey(User) title = models.CharField('title', max_length=100, default='', blank=True, help_text='Use an indicative name, related to the chosen parameters') type = models.CharField('forecast type', choices=FORECAST_TYPES, max_length=20, default="backtest") #input characteristics price_1_min = models.FloatField('1.

PLS-00201 identifier 'PACKAGENAME.PROCEDURENAME' must be declared
iam working on the Backend of a Chat System, used whit Django Server. I wrote an procedure in SQL-Developer for the Oracle Database, which should provide the recent messages to an endpoint.

Django: understanding .values() and .values_list() use cases
I'm having trouble understanding under what circumstances are .values() or .values_list() better than just using Model instances? I think the following are all equivalent: results = SomeModel.objects.all() for result in results: print(result.some_field) results = SomeModel.objects.all().values() for result in results: print(result['some_field']) results = SomeModel.objects.all().values_list() for some_field, another_field in results: print(some_field) obviously these are stupid examples, could anyone point out a good reason for using .values() / .values_list() over just using Model instances directly? -
Django REST views: return images without models
I am completely new to Django REST, and I have been wasting time googling for a way to accomplish something that does not seem to be excessively difficult. I want to define a view using the Django predefined classes for views. This view should return an image (given its name), so a URL like this would return the image example.png: http://localhost:8000/api/v1/image/example.png However I do not want this image to be stored in a model (it would be stored in the server as a png file). The class rest_framework.generics.RetrieveAPIView seems to suit my needs, as I can set permissions and authentication classes to restrict the access to the images, but I cannot figure out how to set the queryset if I do not have a model with my images. Any ideas on this? Thanks and forgive my ignorance. -

Running tests in django throws exception 'doesn't declare explicit app_label'

Check if a user has voted on a Post, in the template
Here's my Post model: models class Post(models.Model): user = models.ForeignKey(User, blank=True, null=True) title = models.TextField(max_length=76) content = models.TextField(null=True, blank=True) ... class PostScore(models.Model): user = models.ForeignKey(User, blank=True, null=True) post = models.ForeignKey(Post, related_name='score') upvotes = models.IntegerField(default=0) downvotes = models.IntegerField(default=0) And here's my template. I want to do something like this... if the user has upvoted or downvoted the Post, then hide the upvote/downvote buttons: {% if request.user in Post.has_answered %} {% else %} <img src="upvote.png" class="upvote" /> <img src="downvote.png" class="downvote" /> {% endif %} I planned to do this by adding a ManyToManyField called has_answered to my Post model, but i'm unable to do that as I get this error: post.Post.has_answered: (fields.E304) Reverse accessor for 'Post.has_answered' clashes with reverse accessor for 'Post.user'.

Django/Python http.server access 404s via proxy, works locally
I've previously had the issue that I couldn't pinpoint the culprit in my Django app, causing all requests to 404. See the previous Stackoverflow question. Since then I've tried to narrow down the issue and therefore started a new, VERY basic, Django app. All the project consists of is: $ django-admin startproject tempor I've added the test directory and imported the test function $ vi tempor/tempor/urls.py from django.conf.urls import url from django.contrib import admin from tempor.views import test urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^test/$', test), ] The views.py and the test function $ vi tempor/tempor/views.py from django.http import HttpResponse def test(request): return HttpResponse("OKAY") Then I migrated the project - as suggested by Django: $ python manage.py check $ python manage.py migrate Now I run the server: $ python3 manage.py runserver 0.0.0.0:8282 Access from the server locally: $ curl localhost:8282/test/ OKAY $ curl <server-public-IP>:8282/test/ OKAY Access from an external system (via proxy) $ curl <server-public-IP>:8282/test/ <!DOCTYPE html> <html lang="en"> [...] <h1>Page not found <span>(404)</span></h1> [...] </html> In the settings.py I have: ALLOWED_HOSTS = ['*'] If I don't use '*', the external system is informed accordingly, as debugging is on: $ curl <server-public-IP>:8282/test/ [...] DisallowedHost at http://<server-public-IP>:8282/test/ [...] This also occurs, if … -

Django: Splitting one app into multiple: Templates, Proxy Models & ForeignKeys
To keep my project cleaner I decided (maybe wrongly) to split my one Django app into two. One app for the management of information, the other for display. And for this I thought using Django Proxy Models in the display App would be the best way. However, I've come across a problem with the ForeignKey fields within certain models and forcing those foreign keys to use a proxy-model, instead of its originating model. Here's some examples to make it clearer: App_1-model.py class Recipe(models.Model): name = models.CharField(max_length=200) slug = models.SlugField() ... class Ingredient(models.Model): name = models.CharField(max_length=200) recipe = models.ForeignKey(Recipe) weight = models.IntegerField() App_2-model.py (Imports App_1 models) class RecipeDisplayProxy(Recipe): class Meta: proxy = True @property def total_weight(self): # routine to calculate total weight return '100g' class IngredientDisplayProxy(Ingredient): class Meta: proxy = True @property def weight_lbs(self): # routine to convert the original weight (grams) to lbs return '2lb' App_2.views.py def display_recipe(request, slug): recipe = get_object_or_404(RecipeDisplayProxy, slug=slug) return render( request, 'display_recipe/recipe.html', {'recipe': recipe} ) App_2-template.html <h2 class="display-4">{{ recipe.name }}</h2> <p>{{ recipe.total_weight }}</p> <!-- This works fine, as expected //--> <ul> {% for recipe_ingredient in recipe.ingredient_set.all %} <li>{{recipe_ingredient.ingredient}} &ndash; {{recipe_ingredient.weight_lbs}}</li> <!-- The above line doesn't return anything as the 'Ingredient' model, not the "IngredientDisplayProxy' is … -

Django slow query since unable to use related set
I am using version 1.8 class ProductProduct(models.Model): product_tmpl = models.ForeignKey(ProductTemplateModel) default_code = models.CharField() name_template = models.CharField() ... class PurchaseOrder(models.Model): # fields... class PurchaseOrderLine(models.Model): id = models.IntegerField() product_id = models.ForeignKey(ProductProduct) order_id = models.ForeignKey(PurchaseOrder) I only need to list the PurchaseOrder records which default_code (in ProductProduct model) is null. I cannot filter using "purchaseorderline_set.product_id_set.default_code=None" since purchaseorderline_set is a query set and it does not have an attribute product_id_set as indicated here. So I tried using this: orders_recs = PurchaseOrder.objects.all().order_by('-id') orders_recs = PurchaseOrder.objects.filter(purchaseorderline_set.product_id_set.default_code=None).order_by('-id') orders = [] for order_rec in orders_recs: line = order_rec.purchaseorderline_set.all() if line and line[0].product_id.default_code == None: orders.append(order_rec) But it's taking over 3 secs. I consider this A LOT taking in consideration that I am only one working in my DEV env (machine is NOT slow) and DB is really small so far, since there are only 269 PurchaseOrder recs, 396 PurchaseOrderLine recs and 726 ProductProduct recs. I suppose there is an efficient way that I am not seeing. -
