Wagtail/Django translations not showing

Django save aggregation in master/detail (many to one relationship)?
I have two models, Order and OrderRow (1:n). What I would like is when something changes on the OrderRow (added, removed, price change, etc.) that that "effect" is calculated to the parent Order. In this case, sum the total of all the OrderRow in Order. The OrderRow (a admin.TabularInline subclass) is setup as inlines on Order. I did implement the django.db.models.signals.post_save but the problem here is that the Order post_save is fired before the OrderRow updates. Is there any nice way (besides implementing a db trigger) for updating this the 'django-way' ? All this under Django Admin -
How can I create a model in django that has a foreign key to one of multiple models?
I want to create a foreign key that can have a reference to exactly one of three other models. example: user fav_animal: foreign_key(bear, cat, dog) bear name cat name dog name How can I achieve this in django? Do I just create 3 nullable foreign keys? Then how do I enforce that always exactly one of them is set? -
How can I generate a rest viewset for all child models based on a parent model
I have the following models based on a shared base model: class Pet(models.Model): created = models.DateTimeField(auto_now_add=True) user = models.ForeignKey('auth.User', related_name='pet', on_delete=models.CASCADE) name=models.CharField(max=100) class Meta: abstract = True ordering = ['-created'] def __str__(self): return str(self.id) class Dog(Pet): legs = models.BigIntegerField() class Bird(Pet): wings = models.BigIntegerField() cage = models.BigIntegerField() Now I would like to get a rest ViewSet that looks like this when I ask for a User: { username: "PeterSchmidt" email:"ps@gmail.com" pets{ { name="shaggy" type="dog" legs=4 } { name="Jaques" type="bird" wings=2 cage=1 } } } Basicly I want a way of having a baseclass model that has its own viewset (multiple serilizers are fine) that I can just use to get all the pets no matter what type they are. Can this be done within standard django rest? -
Why do i get an error when creating a charge with Stripe API in django?

Angular: differentiate between sessions in different tabs
I'm developing a web application. The front end is with Angular and back-end is a Rest API with django rest framework. For some customer requirements, I need that the django rest api is able to differentiate between polling requests with a sessionid. After some searches I found that I can identify the session in the REST API side with the value of: request.session.session_key But that isn't the best choice, because for two different tabs I get the same session_key and the desired sessionId that the rest api receives in the request should identify session for specific tab. So not sessionid for different PCs and host IP address, or browsers only, but also it should get two different sessionids for two different tabs. Does django request object contain other id to identify host tabs? I guess that the solution can be found in Angular side. Is there a way in Angular and typescript to identify tabs sessions? -
Django annotation with multiple rows in Subquery , is it possible?
I have a a question regarding annotation. Firstly, I have 2 related models, that are used in annotation subquery. Secondary model. class UserBriefcaseAttribute(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='user_briefcase_attributes') briefcase_attribute = models.ForeignKey( BriefcaseAttribute, on_delete=models.CASCADE, related_name='+' ) amount = models.IntegerField(default=0) and primary mode for this one class BriefcaseAttribute(models.Model): code = models.CharField(max_length=45) display_name = models.CharField(max_length=45) basically I want to do something like this: SomeModel.objects.filter(**filtering).annotate( result = Subquery(UserBriefcaseAttribute.objects.filter(user=self.request.user, briefcase_attribute__code__in=('silver', 'gold', 'black')).values(‘amount’)) ) Obviously, it doesn't work as subquery returns 3 rows instead of one. I dont know how to deal with it, tried a lot of things already. Expected result should be something like: {‘silver’: 30, ‘gold’: 20, ‘black’: 8} for example or any structure that would be possible to use in DRF serializer Dictfield, or JsonField or Lisfiled or any appropriate field that would be able to render pairs of code: amount (read_only=True). It is possible to do it in separate query but I would prefer to do it via annotation somehow to have only one query. Thanks. -

Custom Django Model Form Field that Aggregates Multiple Instances of an Input
I have created a custom field in a model form that I want to use to enable users to enter multiple instances of inputs into. For example, the custom field is a series of values that corresponds to multiple dates. Once the form is submitted I want to consolidate all of those values into a string and store them in a single database field. See code below. The cleaned_data fields are empty when I add multiple values to the inputs. I think I need to access the input data before it is passed to cleaned_data, but I'm not sure how. Any assistance would be appreciated. #forms.py class UpdateModelForm(forms.ModelForm): custom_field = forms.CharField() class Meta: model = Model def clean_custom_field(self): custom_field = self.cleaned_data['custom_field'] return custom_field def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) #I've tried to access the input fields here without success #views.py class ModelView(UpdateView): model = Model form_class = UpdateModelForm template_name = 'model_edit.html' def form_valid(self, form): #not sure what to put here #model_edit.py <body> <form action="" method="post">{% csrf_token %} <table> <thead> <tr> <th>Amount</th> </thead> <tbody> {% for i in '12345'|make_list %} <tr> <td> {{form.custom_field}} </td> </tr> {% endfor %} </tbody> </table> </form> </body> -

Reload only MultipleChoiceField of dajngo on jquery load
I have a popup-modal in the page to add new data with ajax, after the data is added i have to bring it to the django multichoicefield widget if I try it to bring it in selected portion it is dispalyed and works on submission but after that if user select and bring another data to selected side the one i have added will get destroyed it doesn't compile with the original data that are loaded. I also try to refresh only that portion to again load whole data so that it compile with js function. But now the multichoicefield will not construct through JS and will not display properly. Both of my method I can't work properly, I have changed little js of admin SelectFilter2 to load it in my popup-modal while ajax call that has worked but i didn't get what is causing js not to work on jquery load or addition of new data. Method 1: I append the data to selected side on ajax success $('#id_Course_Group_to').append(`<option value="`+ response.pk + `" title="` + id_InningGroup_Name + `" selected>` + id_InningGroup_Name + `</option>`); This data will not function like other data which are preloaded it will just disappear if … -
What does '|' in {{ services|pprint|safe }} mean in django?
I know that in views.py file: def index(request): person= {'firstname': 'Craig', 'lastname': 'Daniels'} weather= "sunny" context= { 'person': person, 'weather': weather, } return render(request, 'Articles/greeting.html', context) Then we can do in greetings.html: <h1>Hi {{ person.firstname }} {{ person.lastname }}</h1> <h1>Today it is {{ weather }}</h1> where {{ person.firstname }} is a variable defined in context. But what does '|' mean? {{ services|pprint|safe }} -
Is it possible to deploy django 2.2 on Google cloud engine?
I just began to learn Django recently. I am trying to deploy a django project on google cloud engine. But I stuck when following tutorial on google: https://cloud.google.com/python/django/appengine when I type: python manage.py makemigration I got: following error: mysqlclient 1.3.13 or newer is required; you have 0.9.3. After short research, aparently, I can't install mysqlclient 1.3.13 on Django 2.2 yet?? Is this a mistake? Am I missing something? Can I use mysqlclient 1.3.13 on django 2.2 ? Thank you for your time. -
assertEqual fails in Django test view
I'm testing whether the view returns in the context object all the database models that I've saved. The models actually render in the templates when the site is running but having had problems rendering them in the past, I need the view test to help with debugging. So the test collects then saves the site url to the variable resp using Client. I then assertTrue that the key value passed in the context exists. Then - and this is where the problem lies - i attempt to assetEqual that what's in the context object matches whats in my database and this is the resulting traceback: File "/Users/Sol/src/projects/portfolio/python_website/main/tests_models.py", line 24, in check_context_obj self.assertEqual(resp.context['projects'], Project.objects.all()) AssertionError: <Quer[20 chars] App>, <Project: Folium Web Map>, <Project: Personal Webiste>]> != <Quer[20 chars] App>, <Project: Folium Web Map>, <Project: Personal Webiste>]> You'll notice after the AssertionError the the values either side of the != operator are actually exactly the same (I actually checked that their types are the same). Here are my files: tests_views.py from django.test import TestCase from main.models import Project from django.urls import reverse def check_context_obj(self): url = reverse('site_index') resp = self.client.get(url) self.assertTrue(resp.context['projects']) self.assertEqual(resp.context['projects'], Project.objects.all()) views.py from django.shortcuts import get_object_or_404, render from main.models import … -
What is the difference between “return my_view” and “return redirect(my_view)” and how to get a mixed result?
I have a home in which I have a form that I get some info from students to suggest them some programs to apply to. The home view is as below: def home(request): template_name = 'home.html' home_context = {} if request.POST: my_form = MyModelForm(request.POST) if my_form.is_valid(): # do some stuff return programs(request) else: my_form = MyModelForm() home_context.update({'my_form': my_form, }) return render(request, template_name, home_context) In the second view, I have the same form and I want this form to be pre-occupied with the information I entered in the home page. That is why in the above, I passed my POST request to programs view that is as below: def programs(request): template_name = 'programs.html' programs_context = {} if request.POST: my_form = MyModelForm(request.POST) if my_form.is_valid(): # do some other stuff else: my_form = MyModelForm() programs_context.update({'my_form': my_form, }) return render(request, template_name, programs_context) The drawback of this strategy (passing the POST request in the home view to the programs_view) is that the url in url bar does not change to 'example.com/programs' and stays as 'example.com' . I will have some problems including problems in pagination of the programs. The alternative is that I do this: def home(request): template_name = 'home.html' home_context = {} if request.POST: …
