Custom function which performs create and update on DRF modelViewSet
Hi there i have two models the Heat and Breeding. I want to create a custom method in a modelviewset which needs to perform a save and an update logic. Here is my breeding.viewsets.py class BreedingViewSet(viewsets.ModelViewSet): queryset = Breeding.objects.all() serializer_class = BreedingSerializer Since the above method has a higher level of abstraction and is actually providing or performing automatic CRUD functions. Now the problem here is i dont have any control for a multiple transaction like saving an object and updating another object in a single function. e.g @transaction.atomic() def save_and_update(self, request): do save breeding here. do update a heat here. This is my heat.models.py class Heat(models.Model): # Fields performer = models.CharField(max_length=25) is_bred = models.BooleanField(default=False) note = models.TextField(max_length=250, blank=True, null=True) This is my breeding.model.py class Breeding(models.Model): # Relationship Fields heat = models.OneToOneField( Heat, on_delete=models.CASCADE) # Fields performer = models.CharField(max_length=25) remarks = models.TextField(max_length=255, blank=True, null=True) How can we achieve such powerful functionalities? Did i missed something? I found this documentation but i dont know how to implement the given instruction. -
Using RenderContext in render_to_string in Django 1.10
I'm upgrading a project to Django 1.10 and trying to change the following template tag (simplified) @register.simple_tag(takes_context=True) def render_svg(context, svg_template_file_name, *args, **kwargs): svg_string = render_to_string(svg_template_file_name, context, request=context.request) This no longer works since the context passed in is a RenderContext, where the docs state: If you’re passing a Context in context_instance, pass a dict in the context parameter instead. If you’re passing a RequestContext, pass the request separately in the request parameter. Which I'm already doing and still would like to make use of the context parameter to render_to_string... So how can I get a usable dictionary from a RenderContext? -
How can I test that I got back a MagicMock that I injected?
Here is a little class (in myapp/getters.py): from django.contrib.auth.models import User class UserGetter: def get_user(self): return User.objects.get(username='username') I would like to mock out the call to User.objects.get, return a MagicMock, and test that the method returns what I injected. In myapp/tests/tests_getters.py: from unittest import TestCase from django.contrib.auth.models import User, UserManager from mock import patch, create_autospec from myapp.getters import UserGetter class MockTestCase(TestCase): @patch('myapp.getters.User', autospec=True) def test(self, user_class): user = create_autospec(User) objects = create_autospec(UserManager) objects.get.return_value = user user_class.objects.return_value = objects self.assertEquals(user, UserGetter().get_user()) But when I run this test (with python manage.py test myapp.tests.tests_getters) I get AssertionError: <MagicMock name='User.objects().get()' spec='User' id='4354507472'> != <MagicMock name='User.objects.get()' id='4360679248'> Why do I not get back the mock I injected? How can I write this test correctly? -
Provide different kwargs for each form in formset
I am trying to use a formset to create forms for a set of timeframes related to dates: class Event(models.Model): date = models.DateField() class TimeFrame(models.Model): start = models.DateTimeField() end = models.DateTimeField() event = models.ForeignKey('Event') I have code that gets me a queryset of timeframes for each event and added a kwarg to pass this into my form: class SelectDatesForm(forms.Form): timeframes = forms.ModelChoiceField(queryset=HostTimeFrame.objects.none()) def __init__(self, *args, **kwargs): qs = kwargs.pop('timeframes') super(SelectDatesForm, self).__init__(*args, **kwargs) self.fields['timeframes'].queryset = qs Now I'm trying to construct a formset that lets me show timeframes for multiple events on one page. I already found this question, explaining how to pass initial data, for serveral forms, but its not the same as passing it to a queryset. Also there is this new function from django 1.9 but it doesnt allow me to get different querysets for each form. -
Django Models with Choices as Integer
I am trying to make a feedback app in Django, but I can not make my evaluations. In my models.py, I have 5 choices from very bad to excellent. But I want them to be usable as numbers so I can evaluate the overall value. After reading Set Django IntegerField by choices=... name I changed my Ratings from VERYBAD = 'Very bad' to VERYBAD = 1 but no I can't even save my value/form. Feedback(models.Model): event = models.ForeignKey(Event) # Choice VERYBAD = 'Very bad' #old BAD = 2 #new OKAY = 3 GOOD = 4 EXCELLENT = 5 RATING = ( (VERYBAD, 'Very bad'), (BAD, 'Bad'), (OKAY, 'Okay'), (GOOD, 'Good'), (EXCELLENT, 'Excellent'), ) # The ratings organisation = models.CharField( max_length=9, choices=RATING, default=OKAY, ) .... So in my view, I thought I can do the math but I can not. def rating(request, event_id): myevent = Event.objects.get(id=event_id) feedback_items = Feedback.objects.filter(event=myevent) num_of_items = len(feedback_items) def evaluate(feedback_items): # The overall rating organisation = 0 for item in feedback_items: organisation += item.organisation organisation /= num_of_items context = {'feedback_items':feedback_items, 'num_of_items': num_of_items, 'myevent': myevent,} return render(request, 'feedback/rating.html', context) ` -
Simple Django Reverse URL with Parameters not working

Handling JavaScript testing for VanillaJS, dropzone.js and Django project
I'm working on a project that at this point mostly involves custom code written in VanillaJS to communicate with a Django backend. I'm very new to software testing in general, so I am a bit at a loss as to how to best handle unit testing or generally just testing the JavaScript code I've written. Is there even a case for unit testing here, because currently I mostly just hook to different dropzone.js event handlers and get my code ran. For example, there's this: custom_dropzone.on('removedfile', function(file) { removeFileFromServer(file); }); or this: custom_dropzone.on('success', function(file, response) { file.id = response.id; }); The removeFileFromServer(file) function is something that surely COULD be unit tested, but it would require a lot of digging in the original dropzone.js code to get all the necessary attributes right for 'file' and then a way to trigger it. The backend is at the time quite extensively tested and I trust that if anything strange starts to happen, it will be quickly caught in either the backend test suite or by exploratory testing. Maybe Selenium and functional tests could be a better way forwards? I feel I've been so deeply convinced to "test all the things" by what I've read … -
Adding SSL certificates to a mysql docker container
I am building a docker container for a django application, which uses nginx and uwsgi. For the Database the application is using mysql, which is located in a different container and both of them are link with a docker-compose.yml file: version: '2' services: mysql: image: mysql:latest environment: -MYSQL_DATABASE: TheDatabase -MYSQL_ALLOW_EMPTY_PASSWORD: 'yes' -MYSQL_USER: TheUsername -MYSQL_PASSWORD: ThePassword ports: -"3306:3306" django: build: . volumes: - .:/app ports: - "443:443" - "8000:8000" links: - mysql I am using SSL certificates, which are self-signed using OpenSSL and are included in the nginx.conf file. The problem is that every time I run the containers and try to log as the superuser I get the following error 504 Timed Out. After a decent amount of thinking I came to the conclusion that the issue is in the connection to the mysql database. I did enter the mysql container and saw that the Database is there and after inspecting the tables, I saw that all the tables have been created. However, after reading the logs I noticed the following line: [Warning] Failed to set up SSL because of the following SSL library error: SSL context is not usable without certificate and private key. How am I supposed to … -
Django web page- how to manipulate what information is displayed in a table
I have a Django project, and one of my views renders a page that displays a table with information about objects in the database. The objects displayed differ based on the criteria determined in the view. The if statement used in the view to determine which page to render is: if request.GET.get('stage') == 'pd': """ Render post deposit homepage """ print "request.GET.get('stage') == 'pd' " print "render_to_string() called with parameter: costing/report2_ccis.html" context['html'] = render_to_string('costing/report2_ccis.html', context) context['active_tab'] = '4' if(project.deposit_received == True): print "costing/reports_post_deposit.html is the page being rendered (project.deposit_received = true)... " return render(request, 'costing/reports_post_deposit.html', context) elif(project.deposit_received == False): print "costing/reports_pre_deposit.html is the page being rendered (project.deposit_received = False)..." return render(request, 'costing/reports_pre_deposit.html', context) else: """ Render pre deposit homepage """ print "request.GET.get('stage') != 'pd' " print "render_to_string() called with parameter: costing/report_ccis.html" context['html'] = render_to_string('costing/report_ccis.html', context) context['active_tab'] = '5' if(project.deposit_received == True): print "costing/reports_post_deposit.html is the page being rendered (project.deposit_received = true)..." return render(request, 'costing/reports_post_deposit.html', context) elif(project.deposit_received == False): print "costing/reports_pre_deposit.html is the page being rendered (project.deposit_received = false)..." return render(request, 'costing/reports_pre_deposit.html', context) Both of the templates returned in the view extend another template called reports_tabbed.html, and the report_ccis.html & report2_ccis.html templates that are passed to the render_to_string view both extends … -
Use Django model IntegerField validator values on the form
I am able to set the minimum value validator on the model: class MyModel(Model): my_field = models.fields.IntegerField(default=250, validators=[MinValueValidator(30)]) Then I create a form using the previous model: class MyForm(ModelForm): class Meta: model = MyModel fields = ('my_field',) The form gets validated, the correct error message is displayed (when entered value is <30), but even when entered wrong value, it gets saved on the instance! I was able to make it work by specifying (again) the min value on the form: class MyForm(ModelForm): my_field = form.IntegerField(min_value=30) class Meta: model = MyModel fields = ('my_field',) But this way the code is not dry - I need to specify the value and field type twice. Is there any way I could avoid this? Or at least get the min_value from the model validator? -

Django: assertEqual(response.status_code, 200): I want to see useful traceback
If I use the django testing web client like this, I get a useless traceback: def test_details(self): # Issue a GET request. response = self.client.get('/customer/details/') # Check that the response is 200 OK. self.assertEqual(response.status_code, 200) Source: https://docs.djangoproject.com/en/1.10/topics/testing/tools/#example It's useless for me, since I see the traceback of the assertEqual() method. A useful traceback for me in this context would show me the traceback where the Response with the unexpected status_code was created. How could this be done? -

Django Partial mocking implementation
I wrote an unit test for attendance system written in python. It checks that NAT (not assigned time) is updated over time. In the test I have to wait for change in the NAT. Sleep method was used, but I am not happy with this solution. NAT is calculated with use of datetime.now(). I tried to mock datetime.now() with partial mock like in the link: https://docs.python.org/3/library/unittest.mock-examples.html#partial-mocking It is error free, but the time delay is not created. tests.py and models.py are in same folder Python 3.5.2, Django 1.10.3 tests.py code: .... from .models import Session from datetime import datetime, timedelta from django.utils import timezone from unittest.mock import patch class SessionTestCase(TestCase): .... def test_NAT_value_of_opened_session_is_updated_overtime_if_IN_swipe_is_corrected(self): user1 = UserFactory() swipe1 = SwipeFactory(user = user1, swipe_type = "IN") swipe2 = SwipeFactory( # correction of swipe1 user = user1, swipe_type = "IN", correction_of_swipe = swipe1, datetime = swipe1.datetime + timedelta(seconds = 1), ) nat_1 = swipe2.session.get_not_assigned_duration() with patch('attendance.models.datetime') as mock_date: mock_date.now(timezone.utc).return_value = datetime.now(timezone.utc) + timedelta(seconds = 1) mock_date.side_effect = lambda *args, **kw: date(*args, **kw) nat_2 = swipe2.session.get_not_assigned_duration() self.assertNotEqual(nat_1, nat_2) .... models.py code: .... from django.db import models from datetime import datetime, timezone, timedelta .... class Session(models.Model): .... def session_duration_overall(self): .... end_datetime = datime.now(timezone.utc) return end_datetime … -

How to add custom, non-model fields dynamically to Django ModelAdmin or ModalForm?
I am trying to create custom fields for my modal in Django Admin. I have two models - Page and PageTemplate. PageTemplate stores all the needed custom fields for the Page and has a property custom_fields = JSONField(default={}). Page has a OneToOne relationship to PageTemplate. Page also has a custom_fields = JSONField(deafult={}). This property stores the values for the page. Here is my admin and form signature: class PageAdmin(TranslatableAdmin): form = PageForm fields = ['title', 'slug', 'body', 'parent', 'template', 'test'] class PageTemplateAdmin(admin.ModelAdmin): search_fields = ['name', 'slug'] list_display = ['name', 'slug'] fields = ['name', 'slug', 'custom_fields'] class PageForm(TranslatableModelForm): def __init__(self, *args, **kwargs): super(PageForm, self).__init__(*args, **kwargs) if 'instance' in kwargs: instance = kwargs['instance'] if instance.template: custom_fields = instance.template.custom_fields # Add a test field so that it shows it in admin: self.fields['test'] = forms.DateField() class Meta: model = Page exclude = () This system will work in the following way: If a template is given to Page, it will read the custom_fields property of PageTemplate from the OneToOne relationship and display them with the given widgets in Page. Then just get the values from Page's custom_fields property and populate the added Page Template custom_fields with the retrieved data. Before save, these fields will … -

Unable to upload file via Python Django 1.10.3

Django and JSON/AJAX testing
I tried looking around for an answer and gave it a great many tries, but there's something strange going on here. I got some functions in my view that operate on JSON data that comes in via AJAX. Currently I'm trying to do some unit testin on these. In my test case I have: kwargs = {'HTTP_X_REQUESTED_WITH': 'XMLHttpRequest'} url = '/<correct_url>/upload/' data = { "id" : p.id } c = Client() response = c.delete(url, data, **kwargs) content_unicode = response.content.decode('utf-8') content = json.loads(content_unicode) p.id is just an integer that comes from a model I'm using. I then have a function that is being tested, parts of which looks like follows: def delete_ajax(self, request, *args, **kwargs): print (request.body) body_unicode = request.body.decode('utf-8') print (body_unicode) body_json = json.loads(body_unicode) The first print statement yields: .....b"{'id': 1}" The other one: {'id': 1} and finally I get an error for fourth line as follows: json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1) What's going wrong here? I understand that correct JSON format should be {"id": 1} and that's what I'm sending from my test case. But somewhere along the way single-quotes are introduced into the mix causing me head ache.

Creating users with custom attributes: the post_save signal seems not to be received

How to take values from checkboxes row by row from a table and update DB using django
I am trying to get the value of some checkboxes and update database for the rows that are checked. I don’t really know how to do it since I am only starting with Django/python.
