Django 2 get user `id` upon making request on forms.py
My forms.py that appears to contain the error in retriving the user id value upon submitting the form. from django.contrib.auth.models import User from Scanner.models import T class SubmitD(ModelForm): #model form fields here class Meta: model = T fields = ['field1','field2'] def save(self, request): instance = self.cleaned_data #other fields current_user = request.user d.FKtoClient_id = current_user.id d.save() It appears the following line is failing to gather a user id for the user logged in: current_user = request.user d.FKtoClient_id = current_user.id The associated views.py declaration: def APND(request): form = SD(request.POST) # A form bound to the POST data if request.method == 'POST': # If the form has been submitted... if form.is_valid(): # If form input passes initial validation... dnmcleaned = form.cleaned_data['domainNm'] ## clean data in dictionary form.save(request) #save cleaned data to the db from dictionary` try: return HttpResponseRedirect('/PU/?f=' + dnmcleaned) except: raise ValidationError(('Invalid request'), code='300') else: return HttpResponseRedirect('Failure/') else: form = SD() I verified there are (2) users in auth_user table. However, I keep getting this error: (1048, "Column 'FKtoUser_id' cannot be null") How can I resolve this? Thank you. -
How to format a number in django and respect localization
I wrote a custom filter like this which calls this method in a util file: def util_format_number(value): return "{:,.1f}".format(value) The idea is to only show one decimal place...but when used inside a template it won't give me a localized number like I have configured in settings: LANGUAGE_CODE = 'es-es' USE_I18N = True USE_L10N = True USE_THOUSAND_SEPARATOR = True DECIMAL_SEPARATOR = ',' THOUSAND_SEPARATOR = '.' NUMBER_GROUPING = 3 The desired result would be 23.444.523,3 My actual filter looks like this: @register.filter def format_number(value): return util_format_number(value) I want to be able to use the formatter not only in templates, but inside view code where I create custom graphs (that I later print in the templates). Any hints? Best regards and thanks in advance. -
Delete object with form in django
I'm displaying a table. In every line there should be a delete button which deletes the element from the table. My problem is, I'm not sure how to pass the id of the element to the view. html: {% for post in posts %} <div> <h3>Zuletzt ausgewählt:</h3> <p>published: <b>{{ post.pub_date }}</b> </p> <p> name: <b>{{ post.Name }}</b> anmeldung: <b>{{ post.get_Anmeldung_display }}</b> essen: <b>{{ post.get_Essen_display }}</b> <form action="" method="POST"> {% csrf_token %} <input class="btn btn-default btn-danger" name="delete" type="submit" value="Löschen"/> </form> </p> <p> Email: <b>{{ post.Email }}</b> </p> </div> {% endfor %} views.py if request.method == 'POST' and 'delete' in request.POST: Eintrag.objects.filter(pk=id).delete() return HttpResponseRedirect(request.path) So I need to pass post.pub_date of every post to the view, how can I accomplish that? -

how to use cookiecutter-django scss

django run code before model field access? (proxy model fields)
I'm trying to proxy the access of some models' fields. A simple example of the usage I want. @uppercase_fields(['name']) class Book(models.Model): name = models.CharField(max_length=50) # .. more fields .. Given a book instance with name='some_book': Access to book.name should return 'SOME_BOOK' I know it looks weird, but I need an access wrapper like this around model fields that will act as if I'd access the model fields normally. So a method is not an option here. I thought of using __getattr__ but I read it might mess with django internals. Any better way, preferably simple? -

New to Django. Tried looking at tutorials on how to load css files and not working
The website I see when I run the server has not CSS in it, but just the HTML. So far I read that you keep CSS files in a static folder under the project directory. I have an Html template that is in the templates folder and it works perfectly when I load it from the views.home . In the HTML file, I have {% load staticfiles %} at the top of the document, and yes I have checked my installed apps for 'django.contrib.staticfiles' in the settings. Also, in the HTML document, in the href attribute I've added {% static 'style/style.css' %} which is the name of the folder under the static folder. <!DOCTYPE HTML> {% load staticfiles %} <html> <head> <title>night_sky_2</title> <meta name="description" content="website description" /> <meta name="keywords" content="website keywords, website keywords" /> <meta http-equiv="content-type" content="text/html; charset=windows-1252" /> <link rel="stylesheet" type="text/css" href="{% static 'style/style.css' %}" /> </head> -

This happens everytime I try to run the django unit tests that we have written. There are no problems when I runserver or when I do migrations, only when testing. _______ERROR MESSAGE:_________ Liams-MBP:GrammieGram Liam2$ python manage.py test grams Creating test database for alias 'default'...

Unexpected failure to access global flag from inside Django test
I'm trying to add simple mocking to my tests, using a class with static fields to hold the settings (ie. singleton). This works fine when I'm running the test alone, but fails when it is ran as part of the full test suit. For reason the global class is a different class object between the test module and the tested code. ie. here is a simplified example: # in mock_settings.py class MockSettings(object): fake_random = False # in views.py def func(request) print(os.getpid(), id(MockSettings)) if MockSettings.fake_random: return HttpResponse('123') else: return HttpResponse(str(random.randint(1000))) # in tests.py def test_func(self): print(os.getpid(), id(MockSettings)) MockSettings.fake_random = True response = self.client.get('/func') self.assertEquals(response.content, '123') # fails when ran as test suite, works when runs alone Crazy thing #1: when I'm running the test alone (eg. ./manage.py test tests.TestClass.test_func), the id(MockSettings) is the same in the tests.py and the views.py, but when ran in the test suite (eg. ./manage.py test) then the pid matches but the class id is different - and thus fake_random is different... Crazy thing #2: when I tried to reproduce it on a new project, I couldn't. When I commented out all the other tests in my project it still happened. any idea why? -
How to deploy react and django in aws with a ssl and a domain
Currently, I deployed react (port 80 & 443) and django (port 8000) in aws ec2 server. I bought a domain and standard ssl cert. It sets up in react (443). In the server connection of react, it is using axios and connect to domain:8000 but I think it's not a good solution. Safari cannot connect to this kind of connection. Therefore, I add a subdomain: api.domain and change the connection from domain:8000 to api.domain. Since I don't have wildcard ssl cert, so https blocks my api.domain connection in the server. What is the best practice of this case?
