How django load cached result for django prefetch_related? I need to know for debugging it
Looks like some of my code fails to properly use a prefetched query (Using Django/Graphene), resulting in 2N+1 queries... From my understanding, when the property is accessed, django will grab that from prefetch cache if it is prefetched, or grab from DB if not prefetched. So the problem is likely that the code access the property in such a way Django thinks it's not prefetched. So the question is, how can I access the cached result for Django prefetch_related? Which code does the actual grabbing of data (executing raw SQL or get cache) in Django? Sorry if I misunderstood anything since my knowledge of Django is quite limited. -
Linking instance of a model with instance of a different model using ModelForm
I have two models, "Fixture" and "PlayerVotes". The PlayerVotes model has two foreign keys, a link to a particular fixture and the voter (request.user). I want to display the entire list of fixture as an expandable accordion (bootstrap4) and allow the logged in user to give some votes for each instance of fixture.

@csrf_exempt not allowing Angular to send post to Django
I am trying to attach my Angular front end to my Django backend. To do this I have created my own source of session control. I have added this to my view... from django.views.decorators.csrf import csrf_exempt @require_POST @csrf_exempt def my_view_function(request): # do something I have this code on my actual server, and I am hosting Angular locally. When I submit a request I get this error in the google chrome console: Access to XMLHttpRequest at 'https://fake_real_url/signin/checkemail/' from origin 'https://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Django add/edit form not returning initial/default value set while initialisation

Django, Forbidden (CSRF cookie not set.) How to catch when a form submitted and redirect to GET
How do you control over CSRF token error when a client submits the form with POST and if CSRF token error occurs, I'd like to redirect the client to def get which has a form. I found only CSRF_FAILURE_VIEW can be set to an error page but there is nothing I can control over redirection for CSRF error. When the error occurs, Django make an internal server error. So I cannot catch the error in the view. -
Django templates accessing dictionary from another dictionary key
I'm iterating a dictionary, then trying to access another dictionary from a value inside of the previous dictionary. Example: {% for choice in choices %} {{ percentages[choice.id] }} {% endfor %} As in: for choice in choices: percentages[choice.id] Though I get an error: Could not parse the remainder: '[choice.id]' from 'percentages[choice.id]' Which I thought may work. I tried researching and changing [choice.id] into |get:choice.id, but that also gave me an error. -
Two forms in Django- how to make form submittable without all fields full?
I have two forms in one view. I want to be able to submit one form WITHOUT filling out the other. I have figured out how to process the forms seperately by having a different action for each form, but I am using django ModelForms and all fields need to be filled before either form can be submitted. I have tried making the fields optional but it does not work for my use, I need all the fields in each form to be filled out in order to be submitted. Here is my HTML: <form method="post" action="successfulpost" class="form-inline"> {% csrf_token %} {{applicantform}} <input type="submit" class="btn btn-primary" value="View full posting"></input> </div> And my form code: class ApplicantForm(forms.ModelForm): first_name = forms.CharField(widget=forms.TextInput( attrs={'class': 'form-control', 'placeholder': 'First name'}), label='') last_name = forms.CharField(widget=forms.TextInput( attrs={'class': 'form-control', 'placeholder': 'Last name'}), label='') referrer = forms.ModelChoiceField(queryset=Referral.objects.all()) class Meta: model = Applicant fields = ('first_name', 'last_name', 'referrer') Is this possible to do- maybe not possible with ModelForms? -

How to represent a US state in my Django model?
I'm using Django, Python 3.7. I want to represent a US state field in my model. So I added this from django.contrib.localflavor.us.models import USStateField ... class UsLocation(models.Model): address_1 = models.CharField(_("address"), max_length=128) address_2 = models.CharField(_("address cont'd"), max_length=128, blank=True) city = models.CharField(_("city"), max_length=64, null=False) state = USStateField(_("state"), null=False) zip_code = models.CharField(_("zip code"), max_length=10, null=False) Bu tthis is resulting in an "Unresolved reference 'USStateField'" in the import line. I'm not tied to using this library. Is there another way I can conveniently represent a US state and if not, what's wrong with the above? -

I have this test file ... ./web/tests/view_tests.py It looks like the below # Basic test to verify we can get valid return data def test_calculate_tax(self): state = 'MN' gross = 100000 salary = 75000 json_data = json.dumps({'state': state, 'gross': gross, 'salary': salary}) response = c.post('/content/vote/', json_data, content_type='application/json', HTTP_X_REQUESTED_WITH='XMLHttpRequest') self.assertEqual(response.status_code, 302) # this is OK. print(response.content) self.assertEqual(response.content, 2) When I right click the test name in PyCharm and select the "Run Test" option, though, I get the below error. I have no idea what it means or how to fix it ...

Urlize DRF Link
I have a DRF serializer: class ActivitySerializer(serializers.ModelSerializer): link = serializers.CharField(source='get_analytic_link', allow_null=True) class Meta: model = Activity fields = ['link',] In the browsable API, the links are clickable. However, when they are served up to a DataTable via a JSON endpoint, they are (predictably) not clickable. In plain Django, I would do something like this: <td>{{ activity.get_analytic_link|urlize }}</td> How could I replicate that behavior in DRF so that links are clickable? -
How to run a method inside a Model when a JavaScript actionListener is triggered?
I have the next Model: class Post(models.Model): author = models.ForeignKey('auth.User', on_delete=models.CASCADE) title = models.CharField(max_length = 200) text = models.TextField() created_date = models.DateTimeField(default = timezone.now) likes = models.IntegerField(default=0) tags = models.CharField(max_length = 50, default = '' ) def process_likes(self): like = self.likes = F('likes')+1 like.save() def split_tags(self): return self.tags.split() def get_absolute_url(self): return reverse('blog:post_list') def __str__(self): return self.title What I want to do is when a icon in a template is clicked, I want the process_likes method to be run, this method is going to increment by one the value of likes. My script looks like this: <script> let corazon = document.querySelector('.icon-heart-empty'); corazon.addEventListener('click', ()=>{ corazon.classList.toggle('icon-heart'); }); </script> Here I toggle the class of my icon to show if is clicked or uncliked, but how can I call the process_like method using pure JavaScript?
