Assign request.user when saving form clashes with admin panel?
I've got a formset that I'm trying to save, and I'd like for the newly created form to be automatically assigned to the user (request.user). In my models Meta class, I added this: forms.py class Meta: model = Timesheet # fields = "__all__" exclude = ("user", ) and then in views.py class TimesheetCreateView(View): object = None def post(self, request, *args, **kwargs): form = TimesheetModelForm(request.POST) if form.is_valid(): self.object = form.save(commit=False) self.object.user = request.user self.object.save() success_url = reverse("timesheets:current-week", args=(self.object.year, self.object.week)) else: # Warning: Silent form error print(form.errors) success_url = reverse("timesheets:default-current-week") return HttpResponseRedirect(success_url) This works fine, however - if I now go into the admin panel - the dropdown field for user (foreign key) is gone as well. Is there to show all fields in the admin panel, but automatically use the request.user in the template? I tried using fields = "__all" and using the same logic in my views.py file, but I'm getting a form error screaming about "user is required" - I don't want the user have a dropdown menu showing all available users. If I add this in forms.py def __init__(self, user, *args, **kwargs): super(TimesheetModelForm, self).__init__(*args, **kwargs) self.fields['user'].queryset = User.objects.filter(id=user.id) # show logged in user in dropdown The dropdown correctly β¦ -

Django REST Framework filter backend with multiple value?

Django - How to add multiple instances of the same model in a field
I have a class that looks like this. In the pack items I want to have the number of that instance of Item and how many of that as a number. class Item(models.Model): title = models.CharField(max_length=100) price = models.DecimalField(decimal_places=2, max_digits=10) is_pack = models.BooleanField(default=False) pack_items = models.ManyToManyField(PackItem, blank=True) class PackItem(models.Model): packitem = models.ForeignKey('Item', on_delete=models.CASCADE) quantity = models.IntegerField(default=1) This seems to work but every time I create a new pack in the admin, I have to create first, one by one, each PackItem and then put them in the packitems field of Item. The goal is: I have bottles of drinks as Items and I want to have pre-made Packs of these drinks. Would my way of doing it cause problems later on? Is there a better practice? Or is this already wrong? -

How to filter relationships based on their fields in response using Django REST Framework
I have three models: House, Resident, Car. Each House has many Residents (One to Many). Each Resident has 0 or 1 cars (One to One). For my frontend, I want to display all the residents of a house that have a car. Django Rest Framework suggests using Filtering, but this only works at the top level. For example, in my HouseDetailView(generics.RetrieveAPIView), I can only modify the queryset of the House model itself. I want to be able to modify the queryset of the Resident (resident_queryset.exclude(car=None)). class HouseDetailView(generics.RetrieveAPIView): queryset = House.objects.all() serializer_class = HouseSerializer Can/Should I do this all in one request? Are query parameters my only way of filtering? -

Django negated Q model not generating expected query
I have a Django template that contains a set of buttons that pass parameters back to Django based on their activation state using some simple JS. The value passed back in the URL is just the string "Yes". Whenever this value is passed back I want to search for all objects within the model that have a non-null value for that particular field (since the id of the button is actually the string version of the corresponding column in the database and this is why I'm using dictionary unpacking to pass values to the Q model as seen below). The code for this is as follows: for query_obj in data_type_fieldnames+tax_fieldnames: if request.GET.get(query_obj, '') == "Yes": options[query_obj] = None queries = Q() query_list = [] for key in options: query_list.append((~Q(**{key: options[key]}))) queries &= (~Q(**{key: options[key]})) print(query_list) Now suppose I select 4 buttons on the page and submit this button-based form, this is the value of query_list I get back [<Q: (NOT (AND: ('dissimilarity_id', None)))>, <Q: (NOT (AND: ('cartesian_id', None)))>, <Q: (NOT (AND: ('multi_level_id', None)))>, <Q: (NOT (AND: ('stability_id', None)))>] I see the negation operator in there but there is also and AND statement first which I think is what is causing β¦ -

How do I ensure that my Django singleton model exists on startup?
I'm using a django third party app called django-solo to give me a SingletonModel that I can use for some global project settings, since I don't need multiple objects to represent these settings. This works great, but on a fresh database, I need to go in and create an instance of this model, or it won't show up in Django Admin. How can I make django automatically make sure that when django is starting up, when it connects to the database, it creates this? I tried using the following code that I got here in my settings_app/apps.py, but it doesn't seem to fire at any point: from django.db.backends.signals import connection_created def init_my_app(sender, connection, **kwargs): from .models import MyGlobalSettings # This creates an instance of MyGlobalSettings if it doesn't exist MyGlobalSettings.get_solo() print("Instance of MyGlobalSettings created...") class SettingsAppConfig(AppConfig): ... def ready(self): connection_created.connect(init_my_app, sender=self) The instance isn't created, and I don't see my print statement in the logs. Am I doing something wrong? The sample code has something about using post_migrate as well, but I don't need any special code to run after a migration, so I'm not sure that I need that. -

Removing labels from chart.js with a media query (or change option value)
I am using Django and have a bar chart in a view like so: index.html <script> $(document).ready(function(){ var ctx = document.getElementById('pollingBarChart'); var myChart = new Chart(ctx, { type: 'bar', data: { labels: [{% for c in categories %}"{{ c.name }}",{% endfor %}], datasets: [{ label: '# of Votes', data: [{% for a in active_votes %} {{ a }}, {% endfor %}], }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero: true, fontColor: 'white', callback: function(value) {if (value % 1 === 0) {return value;}} } }], xAxes: [{ ticks: { fontColor: 'white', fontSize: 12, } }], }, legend: { labels: { fontColor: 'white' }, }, } }); }); </script> I have figured out I can set the xAxes -> ticks -> fontSize to 0 to achieve what I'm looking for, however I haven't been able to figure out how to change this value to 0 with a media query. I'm still learning JavaScript so not sure the best way to approach this. One possibility I found was to use window.matchMedia("(max-width: 756px)") and add a listener. I wasn't able to get it to work though. Any help would be greatly appreciated. Thank you. -
Django template table format
As I iterate results. There are rows that can be merged, however, relative columns will have multiple rows. For example: Currently: Domain ID----sub Domain Title---- Sub domain ID A1-----------------A1 title-----------A1.1 A1-----------------A1 title-----------A1.2 I would like it to be like this. With first two columns with merged rows Domain ID----sub Domain Title---- Sub domain ID A1----------------A1 title------------A1.1 ---------------------------------------- A1.2 <table class="table table-sm"> <tr> <th>Domain ID</th> <th>Sub Domain title</th> <th>Sub domain ID</th> </tr> {% for record in a6titles %} <tr> <td>A6</td> <td>A6 title</td> <td>titles: {{ record }}</td> </tr> {% endfor %} </table> -
aiohttp api uses db from django app, seems as if database is not migrated

Django template tags - arrange result of queryset
I am trying to format my results in a table. <tr> <td>A6</td> <td>A6 title</td> <td> {% for record in a6titles %} titles: {{ record }} {% endfor %} </td> </tr> The data displays in a single row. I would like each result item to be displayed in its own row. I am sure this is very simple; however, I am very new to this.
