How to bind input fields from model forms into vue
Usually you can grab input fields you manually created through v-model like these: <input class="form-control mb-2" name="username" v-model="username" type="text" placeholder="username" autocomplete="off"> <input class="form-control" type="password" v-model="password" placeholder="password"> However, how can I grab and place v-model on fields that are auto-generated by Django through model forms? <form method="post"> {% csrf_token %} {{ user_form }} <button class="btn btn-primary mt-3">Register</button> </form> -
django-auth-ldap INVALID_CREDENTIALS when authenticating
I am attempting to utilize the django-auth-ldap library however I am unable to connect to the server successfully. When I navigate to the django login screen and use an account associated with our active directory server I get the following error in the logs Caught LDAPError while authenticating user@domain.com: INVALID_CREDENTIALS({'msgtype': 97, 'msgid': 1, 'result': 49, 'desc': 'Invalid credentials', 'ctrls': [], 'info': '80090308: LdapErr: DSID-0C090446, comment: AcceptSecurityContext error, data 52e, v2580'},) I have my settings.py file setup as follows. import ldap, logging from django_auth_ldap.config import LDAPSearch, GroupOfNamesType AUTHENTICATION_BACKENDS = [ "django_auth_ldap.backend.LDAPBackend", "django.contrib.auth.backends.ModelBackend", ] AUTH_LDAP_SERVER_URI = "ldap://serverIP" AUTH_LDAP_AUTHORIZE_ALL_USERS=True AUTH_LDAP_BIND_DN = "cn=service user,OU=ServiceAccounts,dc=domain,dc=com" AUTH_LDAP_BIND_PASSWORD = "password" AUTH_LDAP_USER_SEARCH = LDAPSearch( "dc=domain,dc=com", ldap.SCOPE_SUBTREE, "(sAMAccountName=%(user))" ) # Populate the Django user from the LDAP directory.

Django: annotate() + distinct(fields) is not implemented
I have following models: class Village(models.Model): packages_required = models.IntegerField() . . class PackageSent(models.Model): village = models.ForeignKey('myapp.Village') package_count = models.IntegerField() sending_user = models.ForeignKey('myapp.Users') sending_account_user = models.ForeignKey('myapp.Users') . . And I need to select all Villages along with their PackageSent models. I built the following query: Village.objects.filter( filter_logic ).order_by( order_by_logic ).annotate( packages_missing=F("packages_required") - Sum("packagesent__package_count"), users_involved=Count("packagesent__sending_account_user", distinct=True) ).prefetch_related( models.Prefetch( "packagesent_set", queryset=PackageSent.objects.filter( filter_logic ).annotate( total_account_sent=Sum("package_count"), sending_users=ArrayAgg("sender_user_id") ).distinct( "sending_account_user_id" ), to_attr="packages_sent" ) ) However this query raises annotate() + distinct(fields) is not implemented error. The query I need for PackageSent model in MySQL syntax: SELECT *, SUM(package_count) AS `total_account_sent`, GROUP_CONCAT(sending_user) AS `sending_users` FROM `myapp_packagesent` ps LEFT JOIN `myapp_village` v ON v.id = ps.village_id GROUP BY `sending_account_user`, `village_id` ORDER BY `total_account_sent` DESC I would like to do this in a template: {% for village in object_list %} . . . {% for package_sent in village.packages_sent %} . . . {% endfor %} {% endfor %} How can I achieve the results I want?

Wagtail V2 API force HTTPS for the html_url and detail_url
I am currently developing a portfolio website that has a Django + Wagtail backend to manage the content in a React frontend that talks to each other through Wagtail V2 API and Django-Rest-Framework. I am currently running into an issue where I am able to get the pages from the API, but when my frontend tries to load individual page details the Wagtail v2 API is sending the detail_url as a http url where my nginx setup requires https. I have looked all over the wagtail documentation and stackoverflow for the answer to forcing the detail_url to be a https url but I cannot find the answer or documentation anywhere, nor do I know where to start. What part is causing the http? Is it Django, Wagtail or Rest-Framework? And how do I get it to be https This is what my JSON code looks like from the backend { "meta": { "total_count": 2 }, "items": [ { "id": 3, "meta": { "type": "pages.HomePage", "detail_url": "http://dylan.primic.com/api/v2/pages/3/", "html_url": "http://dylan.primic.com/", "slug": "home", "first_published_at": "2020-09-29T14:58:50.272668Z" }, "title": "Home" }, { "id": 4, "meta": { "type": "pages.AboutPage", "detail_url": "http://dylan.primic.com/api/v2/pages/4/", "html_url": "http://dylan.primic.com/about-me/", "slug": "about-me", "first_published_at": "2020-09-29T15:00:10.624868Z" }, "title": "About Me" } ]} Any help will … -
ManyToManyField with model_to_dict(self)
Not sure if the title is the correct one, sorry for the inconvenience. I'm having a problem on sending a ManyToManyField from a model to a dictionary using the model_to_dict() Below is my code models.py from django.db import models from django.forms import model_to_dict from app_1.models import * class Stuff(models.Model): thing_1 = models.CharField(max_length=100, null=True, blank=True) thing_2 = models.ManyToManyField(OtherStuff, blank=True, related_name="thing") def toJSON(self): item = model_to_dict(self) item['thing'] = self.thing.toJSON() return item When I run a query and load my Stuff model, I get the following error: from app_2.models import * s = Stuff.objects.get(pk=1) # here is where I send my model to a dictionary s.toJSON() Traceback (most recent call last): File "<input>", line 1, in <module> File "P:\test\app\app_2\stuff\models.py", line 10, in toJSON return item AttributeError: 'ManyRelatedManager' object has no attribute 'toJSON' I've come across multiple ways of sending a ManyToManyField to a dictionary, however, none of them use the model_to_dict(). I'd like to use this method due to it's simplicity of usage. -
page is loading very slow
Hi there I have a page and it is loading very slow. I had a very similiar question but this time I guess it requires another solution. I use django for my website and it has some jquerry in the template however I guess that the issue can be on the views. I will post my views and if it is neccessary my templates. Thank you in advance. views.py from django.shortcuts import render import openpyxl def index(request): wb=openpyxl.load_workbook('ders.xlsx') ws=wb.active context_lectures=[] context_lecture=[] context_select=[] for i in range(ws.max_row): day=ws.cell(row=i+1,column=6).value a=0 for j in range(len(day)): if day[j].isupper() and j!=0 and a!=j: day=day[:j]+' - '+day[j:] a=j+3 hour=ws.cell(row=i+1,column=7).value b=0 for k in range(len(hour)): if k%9==0 and k!=0: hour=hour[:k+b]+' - '+hour[k+b:] b+=3 lectures=ws.cell(row=i+1,column=2).value[:4] lecture=ws.cell(row=i+1,column=2).value select=ws.cell(row=i+1,column=1).value+' | '+ws.cell(row=i+1,column=2).value+' | '+ws.cell(row=i+1,column=3).value+' | '+ws.cell(row=i+1,column=4).value+' | '+day+' | '+hour if lectures in context_lectures: pass else: context_lectures.append(lectures) if lecture in context_lecture: pass else: context_lecture.append(lecture) if select in context_select: pass else: context_select.append(select) return render(request,'index.html',{'context_lectures': context_lectures,'context_lecture':context_lecture,'context_select':context_select}) and I would also ask where should I deploy my xlsx file. I didn't found a solution so I deployed it on the main project folder where manage.py is. -
Twilio with Django
I am trying to use Twilio with Django. I have followed this tutorial and it works properly. I am now trying to apply that within my own project. I've taken a copy of package.json into my project's root directory and I've run npm install to set up the node_modules directory. I have also copied the get_token and call views as is. Something is going wrong in the JS because I can see the get_token call but not the call call (if you know what I mean). My call button is an exact copy of the example project and when I click it I get the following error: Received an error from MediaStream: Object { info: {…} } twilio.min.js:99:91242 error http://127.0.0.1:8000/static/twilio.min.js:99 onerror http://127.0.0.1:8000/static/twilio.min.js:99 _initializeMediaStream http://127.0.0.1:8000/static/twilio.min.js:99 makeOutgoingCall http://127.0.0.1:8000/static/twilio.min.js:99 connect http://127.0.0.1:8000/static/twilio.min.js:99 accept http://127.0.0.1:8000/static/twilio.min.js:99 (Async: promise callback) accept http://127.0.0.1:8000/static/twilio.min.js:99 connect http://127.0.0.1:8000/static/twilio.min.js:99 callCustomer http://127.0.0.1:8000/static/prospecting/js/browser-calls.js:106 onclick http://127.0.0.1:8000/?page=3:1 My Twilio settings have been checked, double checked and triple checked.

django: Update dabatase table with a formset
I am confused about formsets. I built a form and a view to insert one database table row that working just fine, and I just built a formset in a view to be able to insert several rows at once. My issue is that the formset does not seem to work. Nothing gets changed in the DB. Here is what my form look like: class ProcurementOperationRecordForm(forms.ModelForm): class Meta: model = replenishment fields = ('Id', 'Quantity', 'NetAmount', 'Supplier', 'SellPrice') and here is what my former view looked like: #def New_Purchase(request): #if request.method == 'POST': #form = ProcurementOperationRecordForm(request.POST) #if form.is_valid(): #form.save() #quantity = form.cleaned_data.get('Quantity') #id = form.cleaned_data.get('Id') #update = replenishment.objects.filter(Id = id).update(StockOnOrder =+ quantity) #update2 = Item2.objects.filter(reference = id).update(en_cours_de_reception =+ quantity) #quantity = form.cleaned_data.get('Quantity') #id = form.cleaned_data.get('Id') #update = replenishment.objects.filter(Id = id).update(StockOnOrder = (StockOnOrder + quantity)) #return redirect('/dash2.html') #else: #form = ProcurementOperationRecordForm() #context = {'form': form,} #return render(request, 'new_purchase.html', context) and here is what my formset view looks like: def New_Purchase(request): context = {} form = formset_factory(ProcurementOperationRecordForm, extra = 3) formset = form() context['formset'] = formset return render(request, 'new_purchase.html', context) I don't know what to do to make this formset works, would someone have a clue that could unblock the situation? -
Django internationalization doesn't work on my system

Django ORM query two ManyToMany relationships, via a ForeignKey relationship
class ThingDefinition(models.Model): ... class Thing(models.Model): definition = ForeignKey(ThingDefinition) class FooGroup(models.Model): thing_definitions = ManyToManyField(ThingDefinition, blank=True) class Bucket(models.Model): contents = ManyToManyField(Thing, blank=True) foo_group = ForeignKey(FooGroup) @property def prop(self): expected_contents = {self.foo_group.thing_definitions} actual_contents = {x.thing_definition for x in self.contents} return bool(expected_contents.difference(actual_contents)) I am trying to write a django ORM query tog get the value of prop. I have written some python which gives the right answer; it is too slow to use, but it should make it clear what I am trying to achieve. To summarise in English: For each Thing in the many to many field self.contents, get the value of the foreign key to ThingDefinition Follow the foreign key relationship self.foo_group, and get the values of the ManyToManyField thing_definitions. Compare these two querysets, and return True if the latter contains things not contained in the former. -
Have Django templates render registration/login form and React rest of the application
Is it a good approach to have Django built-in templates to handle login/registration views, which on successfull login would redirect to a login required view with html template that has the React application embeded in it? Rest of the communication would be a django-rest-framework and React-query or redux-saga on the frontend. Obviously no request without the user authorized will be allowed. -
Using Factory Boy inside a dict for a data model factory in Django? Alternatively, getting FactoryBoy to evaluate subfactory on demand?
I have the following ModelFactory: class ProjectDataModelFactory(DjangoModelFactory): project = factory.SubFactory("projects.factories.ProjectModelFactory") version = "1" content = { "id": {"value": fuzzy.FuzzyText(length=7, chars=string.ascii_letters).fuzz().upper(), "type": "string"}, "win_probability": {"value": fuzzy.FuzzyInteger(0, 100).fuzz(), "type": "number"}, "bid_value": { "value": fuzzy.FuzzyInteger(0, 10000000).fuzz(), "type": "number", }, "status": {"value": random.choice(["Won", "Lost"]), "type": "string"}, "sector": { "value": random.choice( ["Construction", "Technology", "Finance", "Consulting", "Agriculture", "Engineering"] ), "type": "string", }, } In content["id"], I would like to have value be project.external_id instead of fuzzy.FuzzyText(length=7, chars=string.ascii_letters).fuzz().upper(). external_idis part of the ProjectModel. But when I put project.external_id in the place of the fuzzer, I get this error: AttributeError: 'SubFactory' object has no attribute 'external_id This only seems to be a problem with dicts. We have not had issues using it in other contexts. I do not have a lot of experience using FactoryBoy, so it could easily be something trivial. Any ideas? -

I appreciate the help.

Django views opens different content
I am new to Django. I have created 2 seperate views and URLs, however, when I load my development server and click on slides to open slides_detail.html, it opens sub_detail.html, at this point I have no clue what could cause that as there are no similar names which would lead to opening completely different detail page. Both slides and subcontent sits in the same HTML document, same with URLs and views. There are no errors, to show. Thanks in advance: URLS: path('<int:sub_id>/', views.sub_detail, name='sub_detail'), path('<int:slides_id>/', views.slides_detail, name='slides_detail'), Views: # Will show specific sub content details def sub_detail(request, sub_id): subcontent = get_object_or_404(SubContent, pk=sub_id) context = { 'subcontent': subcontent, } return render(request, 'home/sub_detail.html', context) # Will show specific slides content details def slides_detail(request, slides_id): slides = Slides.objects.get(pk=slides_id) context = { 'slides': slides, } return render(request, 'home/slides_detail.html', context) HTML for slides: {% for slides in slides %} <div class="swiper-slide"> <div class="card"> <a href="{% url 'slides_detail' slides.id %}"> <img src="{{ slides.image.url }}" class="card-img-top img-height" alt="..."></a> <div class="card-body bg-dark"> <h5 class="card-title text-light font-weight-bold text-center">{{ slides.title }}</h5> </div> </div> </div> {% endfor %} HTML for subcontent: {% for sub in subcontent %} {% if forloop.counter|divisibleby:2 %} <div class="row"> {% if sub.image %} <div class="col-md-6 section-index-img"> <img … -

Designing search API endpoint with filter and query
I have been looking into designing a RESTful search endpoint and I think most people would agree that using GET method as the best approach to do it. Lets say I am currently designing a website to sell used car and a search endpoint required to search available cars. How do we handle a search endpoint that allows different query params to be added and how we write the url pattern in django? For example /cars?color=red&year=2010&keyword=audi I guess the url pattern would be re_path(/cars/, views.car) and we get the color, year and keyword using request.GET? What about if we to use the /cars/ endpoint to have more specific search? For example further expand the url to include other parameters /cars/toyota and /cars/california/toyota Does that means I will need to include more url patterns for each param added and possible different view for it? urlpatterns = [ re_path(/cars/?P<brand>[\w]+/, views.car_brand_search), re_path(/cars/?P<state>[\w]+/<?P<brand>[\w]+/, views_car_state_brand_search) ] -
