Thread local attribute defined globally not accessible in threads
import threading threadlocal = threading.local() threadlocal.depth = 0 def _increase_depth(): threadlocal.depth += 1 def _decrease_depth(): threadlocal.depth -= 1 def _use_it(): print(threadlocal.depth) But I get: AttributeError: '_thread._local' object has no attribute 'depth' What I would expect: each threads gets a depth initialized to 0, and modifications will only visible within that particular thread. Why are the attributes defined in threadlocal not accessible in the threads? (This code is running in development with the django test server: I have not yet adapted it to produce a mimimum example which can be demonstrated with plain threads) -
django-meta project throws lots of exception in the console
I added django-meta to my project as indicated in the documentation on the GitHub : https://github.com/nephila/django-meta (the complete doc are on ReadTheDocs : https://django-meta.readthedocs.io/en/latest/ I tried to only activate the Twitter META tags (for a start). I copy - pasted the default MetaModel values from the source code of django-meta to initialize an instance variable named meta. in my settings, I set several values as it seems django-meta prefers to receive some value through the settings (instead of being set in the code). In the source code it clearly tries to initialize itself from the settings.

saving in stages in a django view
I am trying to get a field value from the database and modify it by getting the value from the page when it is rendered, The main issue is that I need to keep updating and savings the seconds every time the user refreshes the page. I want to do that on the same view where the user post his final response, I keep getting this error : IntegrityError: NOT NULL constraint failed: study_answer.completion_time although the field in the answer model has a default value: completion_time = models.FloatField(default=30) Completion time should be saved when the user finally submits the answer that comes from a different AJAX post call. views.py def attention_view(request): participant = get_object_or_404(Participant, user=request.user) attention_question = Question.objects.get(id=13) answer, created = Answer.objects.get_or_create(participant=participant, question=attention_question) seconds_left = int(answer.seconds_left) if request.method == 'POST': selected_choice = request.POST.get('selected_choice') completion_time = request.POST.get('completion_time') seconds_left = request.POST.get('left') seconds_left.answer=seconds_left if answer.answer is not None: return HttpResponseRedirect('/study/attention_view') print('already submitted') else: answer.answer = selected_choice answer.completion_time = completion_time answer.save() context = {'attention_question': attention_question, 'seconds_left':seconds_left, 'answer':answer} return render(request, 'study/AttentionCheck.html', context) I tried to save seconds_left in another view and it works but I want to save it in the same view where I have the GET request -
It is possible to obtain some concrete data using the generic view `ListView`?
It is possible to obtain some concrete data using the generic view ListView? I know how to do it creating my own function, but actually I'm using a ListView to show some data and now, I just simply need to know the value of the last row from one column called data_id. This my actual class: class devData_bbdd_view(LoginRequiredMixin, ListView): template_name = 'data_app/data-bbdd.html' paginate_by = 50 queryset = DevData.objects.order_by('-data_timestamp') context_object_name = 'DevDataList' login_url = reverse_lazy('user_app:login') I thought maybe I can do something like last_row = queryset[-1] And from here obtain the the value of the data_id, but it's totally wrong. I suppose I can seriealize the queryset and then do it, but I suppose too is not the best option. How can I do it? Thank you very much! -

Django forms resize CharField/Textarea fields
I'm currently developing a web app with django and I have some forms where the users can enter a lot of text (up to 5.000 chars). I'm doing this using a CharField in forms.py: from django import forms class text_form(forms.Form): ... longer_text = forms.CharField( max_length=5000, widget=forms.Textarea( attrs={ 'rows':10, 'cols':2, 'data-length':5000, }), help_text='Some help text', label = 'Label Text', required=True ) The problems I'm facing right now (and I couldn't solve them even though I read a lot of related SO question) are: 1) I want the users to see a larger field (multiple rows) where they can insert text. Right now it's about maybe two rows and doesn't resize regardless of what I insert as rows value in attrs. 2) The users should be able to use the Enter key on their keyboard within those textareas to make a linebreak Any ideas how to achieve this? And another thought: Maybe it already works and this is a browser related thing? Thanks! -

Django, is it possible to have a formset factory with two ForeingKey?
How can I set two ForeignKey in a inline formset factory? I have created an inline formset factory utilizing two models: Lavorazione and Costi_materiale. class Lavorazione(models.Model): codice_commessa=models.ForeignKey(Informazioni_Generali, ) numero_lavorazione=models.IntegerField() class Costi_materiale(models.Model): codice_commessa=models.ForeignKey(Informazioni_Generali) numero_lavorazione=models.ForeignKey(Lavorazione) prezzo=models.DecimalField() After I have created the inline formset facotry as the following: CostiMaterialeFormSet = inlineformset_factory( Lavorazione, Costi_materiale, form=CostiMaterialeForm, fields="__all__", exclude=('codice_commessa',), can_delete=True, extra=1 ) But I have in Costi_materiale two ForeignKey, instead in the form the formset recognise only numero_lavorazione and not also codice_commesse. I want that the formset set in the first model the codice_commesse and lavorazione fields and subsequently in the inline formset the other fields. -
Django Form Submission button not working
So, I am following code4startup tutorial on how to create a similar to Ubereats app. Right now, I am trying to register a new Restaurant & restaurant owner to the database. I am using a form from Django to handle all the datafields. Everything works fine until I hit the "sign-up" button. My code is SUPPOSED TO POST all the data from the form into the database, then automatically log-in the newly created restaurant owner into the restaurants page. HOWEVER, when i press the sign-up button, nothing happens and instead the sign-up page is reloaded. How can i solve this issue? The tutorial I'm following is from 2017 i think so the django version the author uses is old. Below are some snippets from my code: SIGN-UP HTML (BUTTON ONLY, FORM WORKS OK): <form method="POST" enctype="multipart/form-data" > {% csrf_token %} {{ user_form }} {{ restaurant_form }} <button type="submit">Sign Up</button> VIEWS.py def restaurant_home(request): return render(request, 'restaurant/home.html', {}) def restaurant_sign_up(request): user_form = UserForm() restaurant_form = RestaurantForm() #when submitting data: if request == "POST": user_form = UserForm(request.POST) restaurant_form = RestaurantForm(request.POST, request.FILES) if user_form.is_valid() and restaurant_form.is_valid(): new_user = User.objects.create_user(**user_form.cleaned_data) new_restaurant = restaurant_form.save(commit=False) new_restaurant.user = new_user new_restaurant.save() login(request, authenticate( username = user.form.cleaned_data["username"], password = user.form.cleaned_data["password"] … -
Django add RunSQL operation after adding ForeignKey constraint in migration
I'm using Django 2.1, Python 3.6 and MySQL 8. The database has quite huge table with plenty of big rows, hence migration applied to this table takes hours to complete. I discovered if I remove fulltext index from this table it enables inplace alghorithm of modyfing table - it's muuuch faster. So I need to take advantage of that in Django. I thought about removing fulltext index as first migration operation and create it again after all other operations. operations = [ migrations.CreateModel( name='NewModel', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ], options={ 'abstract': False, }, ), migrations.RunSQL( ('DROP INDEX fulltext_idx_content ON summarizer_model',), ('CREATE FULLTEXT INDEX fulltext_idx_content ON summarizer_model(content)',), ), migrations.AddField( model_name='model', name='new_model', field=models.ForeignKey(null=True, on_delete=django.db.models.deletion.SET_NULL, related_name='new_models_objects', to='summarizer.new_model'), ), migrations.RunSQL( ('CREATE FULLTEXT INDEX fulltext_idx_content ON summarizer_model(content)',), ('DROP INDEX fulltext_idx_content ON summarizer_model',), ), ] (I quickly 'anonymized' above code snipper, so if there is some logical error then please excuse me - this is not the case here :) ) The problem is that Django migration always put adding ForeignKey constraint as last operation. So after my last RunSQL which creates index back. It makes it very slow operation (copy whole table with new column). Is there a way to overcome it? It … -

How to pass value from a python list to a chart?
I have to pass two separate value, data and label, from a python list to chartjs. Here my stuff: data = [[title], [identifier], [subject], [type], [preview], [isReferencedBy], [licence], [licenseMetadata]] label =["title", "identifier", "subject", "type", "preview", "isReferencedBy", "licence", "licenseMetadata"] merge_dataLabel = dict(zip(label,data)) print(merge_dataLabel) Values in data are the results from a sum, values in label are the corresponding label of each result. To associate each label to the corresponding result I'm using zip with this result: {'title': [309], 'identifier': [309], 'subject': [1], 'type': [309], 'preview': [0], 'isReferencedBy': [0], 'licence': [0], 'licenseMetadata': [0]} Before wasting time to integrate chartjs I tried then to render the result via a template: return render ( request , 'completeness.html' , {'merge_dataLabel': merge_dataLabel}) Template: <ul> {% for item in merge_dataLabel %} <li>{{ item }}</li> {% endfor %} </ul> However only the label are rendered without the relative values.

Django `assertNumQueries` showing duplicate queries on deferred field
I am having a strange behaviour that I cannot find out why it's happening. I have a simple queryset with a deferred field, for example Business.objects.filter(id=4).defer('phone') and then I have a test that asserts this: with self.assertNumberQueries(2): b = Business.objects.filter(id=4).defer('phone').first() # 1 query b.phone # 1 query It fails, because it seems to run three queries on that block: the first one when filtering, and two more duplicate queries that come from the b.phone statement (SELECT name ...). Does anyone have any idea why this is happening? -

How to get values from multiple models and filter based on calculation of those values in Django
I have 4 models and i want to make calculation and then filter based on different values from all models: class Profiles(models.Model): name=models.CharField(max_length=200) surname=models.CharField(max_length=200) class Year20(models.Model): name=models.CharField(max_length=200) profiless=models.ManyToManyField(Profiles) math=models.DecimalField(decimal_places=2,max_digits=1000) english=models.DecimalField(decimal_places=2,max_digits=1000) class Year19(models.Model): name=models.CharField(max_length=200) profiless=models.ManyToManyField(Profiles) math=models.DecimalField(decimal_places=2,max_digits=1000) english=models.DecimalField(decimal_places=2,max_digits=1000) class Faculty(models.Model): name=models.CharField(max_length=200) profiless=models.ManyToManyField(Profiles) acting=models.DecimalField(decimal_places=2,max_digits=1000) cooking=models.DecimalField(decimal_places=2,max_digits=1000) I applied ManyToManyField as class Profiles relates to all other 3. I am new to Djnago and I do not know how far that is right. If not please let me know- what is the best and effecient way to organise it. score_19=Year19.objects.annotate( final_grade=F('math') / F('english')).filter(final_grade__gt=61,) Is calculation based on values from one tables-model i want to get final score which is : math_avrg=(year19.math+year20.math)/2 eng_avrg=(year19.eng+year20.eng)/2 final_score=(math_avrg+eng_avrg+acting)/3 which is not code but math claculation that works within view in function. I want to filter values based on final_score and then print surname. I previously asked the question but the answer did not work in my case and was quite cumbersome to follow. I would appreciate if you could share some code to asnwer the question.
