Use original template under admin directory
I have django script with administration page /admin Now I want to make another page /customdata for administration purpose. However in this page , customdata is not related to specific model, it just shows the system overview data. It is just the normal template. Now I have two ideas. Making independent www.myexample.com/customdata page and set authentication. Linking this under www.myexample.com/admin/customdata and treat it as admin page 2 sounds usefule to me, because pages for administration purpose should be togetter. However is it possible? or is it not good behaivor? -
Django (django-rest-framework) with Bootstrap Autocomplete. Filed Nameing
I want to autocomplate a field. But i can't figure out how i can accomplish properly because i don't know yet what is the industry standard. Seems to be the Bootstrap Autocomplete expect an particular field naming like this. I think this is hardcoded. (the "text" at least): [ { "value": 1, "text": "Google Cloud Platform" }, { "value": 2, "text": "Amazon AWS" }, { "value": 3, "text": "Docker" }, { "value": 4, "text": "Digital Ocean" } ] How i can alter/mask the filed names from ['id','provider'] to ['value','text'] in Django side? Let say i have: #modell class CloudProviders(models.Model): provider = models.CharField(max_length=255, blank=True, null=True) #id come by default ... #Serializer class CloudProvidersAutocompleteSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = CloudProviders fields = ['id','provider'] #view class CloudProvidersAutocomplete(viewsets.ModelViewSet): model = CloudProviders serializer_class = CloudProvidersAutocompleteSerializer def get_queryset(self): query= self.request.query_params.get('search') if query : data = CloudProviders.objects.filter(provider__contains=query) return data UPDATE I have a solution but the question still open, because i don't know if this is a proper solution: #modell class CloudProviders(models.Model): provider = models.CharField(max_length=255, blank=True, null=True) #id come by default def _getProvider (self): return self.provider text = property(_getProvider ) ... -
Django Rest Framework Serializers causing errors while Creating Serializers for circular dependent Models

Is it possible to store aware datetime objects in django with different timezones for the values?
I've seen many different posts across SO about aware timezones in django (i.e. datetimes with a timezone value). Even converting naive datetime to aware I've read online that many applications that deal with timezones usually store everything in UTC to avoid any Day light savings conversions and then use frontend to handle the conversions. I'd like to know if it's possible to store an aware datetime with the actual timezone in my database. If so, how would I go about it? So instead of storing something like: 2022-10-13 13:56:00+00:00 I'd like to store: 2022-10-13 13:56:00+04:30 (US/Eastern) -

How can I make a django form field value not refresh if the field is not validated and user hits submit
I have created an HTMl register form template, and designed it such that if there is any validation error, it outputs the error and that works fine. Register form showing "passwords do not match" error The problem I'm having is the whole form fields clear once I hit submit and the errors show up, this was if a user has a "passwords do not match error" he'd have to input all his details from scratch. I want the user to input only the fields that has errors. The register HTML form ` {% csrf_token %} <div class="col-md-12"> <input class="form-control" type="text" name="first_name" placeholder="Firstname" required> {% if form.first_name.errors %} {% for error in form.first_name.errors %} <span style="color:#DC3545;"> {{error}} </span> {% endfor %} {% endif %} </div> <div class="col-md-12"> <input class="form-control" type="text" name="last_name" placeholder="Lastname" required> {% if form.last_name.errors %} {% for error in form.last_name.errors %} <span style="color:#DC3545;"> {{error}} </span> {% endfor %} {% endif %} </div> <div class="col-md-12"> <input class="form-control" type="text" name="email" placeholder="Email address" required> {% if form.email.errors %} {% for error in form.email.errors %} <span style="color:#DC3545;"> {{error}} </span> {% endfor %} {% endif %} </div> <div class="col-md-12"> <input class="form-control" type="password" name="password1" placeholder="Enter Password" required> {% if form.password1.errors %} {% for error in … -

Django object.filter returns Object (1) on search bar
So I have a Django website Project that contains a database of all the different books stored in it. With my search bar, if I type in the name it will show results from the database. The problem is that whenever I type in said name (One Piece or Attack On Titan), instead of showing its title name, it will either show Book Object (1) or Book Object (2) depending on what name I type and I don't know why. This is where I defined my classes: class Book(models.Model): title = models.CharField(max_length=255) author = models.CharField(max_length=255) editor = models.CharField(max_length=255) year_published = models.IntegerField() number_in_stock = models.IntegerField() daily_rate = models.FloatField(null=True) genre = models.ForeignKey(Genre, on_delete=models.CASCADE) date_created = models.DateTimeField(default=timezone.now) manga_image = models.ImageField(null=True, blank=True, upload_to='images/') And this is where I defined my requests: def search_manga(request): if request.method == "POST": searched = request.POST[('searched')] mangas = Book.objects.filter(title__contains=searched) return render(request, 'books/search_manga.html', {'searched': searched, 'mangas': mangas}) else: return render(request,'books/search_manga.html', {}) Also this is the HTML document I'm trying to show the results on: {% extends 'base.html' %} {% block content %} <style> h1 { text-align: center; } </style> {% if searched %} <h1>You Searched For {{searched}}</h1> <br/> {% for manga in mangas %} {{ manga }}<br/> {% endfor %} {% … -

Need help displaying data in a specific format using Django and Python
I am very much a newbie at Django and python, so please be gentle! I have a database with a table that has date, time, position, group number, and the names of the people in each group. This table is for scheduling purposes. The table has several lines with date, depending on the total number of people scheduled per day, three different shifts at the moment (time), and three positions. Each group that fills each position can have a varying number of people in it, and each position has a different number of groups for each time slot. What I want is something that has the date on the first row, the three times on the second row, the three positions under each of the three times on the third row, then list the group number and each person. Row 1: 1 column (date) Row 2: 3 columns (time) Row 3: 9 columns (position) Row 4-? 9 columns (group number, names listed under each group number) Honestly, I have no idea how to accomplish this layout. Any ideas? Here's the code I have so far. Thanks! View: def index(request): context = {} sched= Schedule.objects.all() context['sched'] = sched return render(request, 'index.html', … -

Admin approval and email verification with all-auth
I want to implement an admin approval and email confirmation system for the signup process. For now, I am using the 'is_active' field set False by default, until the admin sets it manually to True. It works so far, the only problem is that the confirmation mail is not being sent out when 'is_active' is False. The email-confirmation flag is actually in another table called accounts_emailaddress, so I am wondering why this is not working? Depending on which flag is set to False, the user should be redirected to the corresponding Templates. The user should not be able to log in, unless the email is verified and his profile approved by the administrator. How can I achieve this result? -
Using VCR mechanics to record and play queries to SQL database
Is it a viable approach to allow recording SQL queries to a file and later loading these queries from the file to memory and playing queries by monkey patching the db driver? I had employed this method in the past for recording http queries to external services with library vcrpy. I don't see any obstacles in implementation. The question is, does it even make sense in terms of test speed improvement? Also, what inconsistencies or pitfalls in usage of such an approach might this cause? -
