Whats the recommended way to update every instance of a source model when a new target instance is created in a manytomany model?
I have a website where I want to display a basic html table like so: Product_Name | Attribute_1 | Attribute_2 ----------------------------------------- Soap | True | True Shampoo | False | True So I have created the classes Product and Attribute with a ManyToMany relationship. Models.py class Product(models.Model): name = models.CharField(max_length=10) attributes = models.ManyToManyField(on_delete='CASCADE') class Attribute(models.Model): name = models.CharField(max_length=1, default='N') So I have two Attribute instances - Attribute_1 and Attribute_2. When I create a new attribute (Attribute_3), is there a way I can update the relationships of all of my Product instances with a link to the new Attribute? I know that Django creates a through table for m2m relationships. According to the docs, I know I can do something like: for prod_obj in Product.objects.all(): prod_obj.add(new_attribute_object) But how do I ensure this happens automatically/consistently every time I create an attribute object? -
Trying to get location_profile to show location.name in __str__ (django)
I have the following 2 models: class LocationProfile(models.Model): units = models.CharField(max_length=100,blank=True) location_notes = models.TextField(blank=True) is_occupied = models.BooleanField(default=False) def __str__(self): return self.location.name class Location(models.Model): organization = models.ForeignKey(Organization, on_delete=None) location_profile = models.OneToOneField(LocationProfile, on_delete=None) name = models.CharField(max_length=255) address1 = models.CharField(max_length=100) def __str__(self): return self.name And I am trying to get LocationProfile to show the name of the Location but the error is: LocationProfile has no location. Each Location has 1 Location Profile, and if possible, I would like to be able to select the Location Profile from the Location dropdown in the django admin (as opposed to going to Location Profile and selecting the Location.) -

A form field with a models foreign key to another model, showing fields by criteria. Django
I am trying to add a field for my form that will return 'business hours' only on that day.

Django 2: Multiple slugs in url
I am currently following a django tutorial by sentdex. The tutorial is making a clone of https://pythonprogramming.net/. In the tutorial he uses only one slug in the url, but i think its more convenient to have multiple slugs beacause the urls will be more organized. For example, a link to a tutorial on pythonprogramming.net looks like this: https://pythonprogramming.net/build-supercomputer-raspberry-pi/. What i want it to look like on my project is mydomain.com/data-analsyis/build-supercomputer/1/. The url would be domain/category/series/episode/, instead of domain/episode/. # urls.py from django.urls import path from . import views app_name = "main" urlpatterns = [ path('', views.homepage, name="homepage"), # View categories path("register/", views.register, name="register"), path("logout/", views.logout_request, name="logout"), path("login/", views.login_request, name="login"), path("<slug:series_slug>/", views.slugs, name="series_blocks"), # Views all the series in that category path("<slug:series_slug>/<slug:tutorial_slug>/", views.slugs, name="tutorial_blocks"), # View all tutorials in series path("<slug:series_slug>/<slug:tutorial_slug>/<int:id>/", views.slugs, name="tutorial_blocks"), # View spesific tutorial nr. ] Note: I think it's better to have 3 different functions than the views.slug # Models.py from django.db import models from datetime import datetime class TutorialCategory(models.Model): category = models.CharField(max_length=100) summary = models.CharField(max_length=200) slug = models.CharField(max_length=100) class Meta: verbose_name_plural = "Kategorier" def __str__(self): return self.category class TutorialSeries(models.Model): series = models.CharField(max_length=200) category = models.ForeignKey(TutorialCategory, default=1, verbose_name="Kategori", on_delete=models.SET_DEFAULT) summary = models.CharField(max_length=200) slug = models.CharField(max_length=100) # Not … -

Django - how can I save cart items in a session

Django ModelForm widgets and labels
When I have a regular ModelForm field, setting up its widgets and/or labels will look like this: class MyModelForm(models.ModelForm): class Meta: model = MyModel fields = ['field_x', 'field_y'] widgets = { 'field_x': Forms.TextInput(attrs={'class': 'myclass', 'readonly': 'readonly'}), 'field_y': Forms.Select(attrs{'class': 'myclass'}), } labels = { 'field_x': 'Input your X value here', 'field_y': 'Select your Y value here', } And it's all ok so far. But when it comes about more "complicated" fields, widgets will ignore its attrs... and it's getting me sick. Example: class MyComplicatedModelForm(forms.ModelForm): field_z = forms.ModelChoiceField(queryset=AnyClass.objects.all(), empty_label=None, required=True, to_field_name='id') class Meta: model = MyComplicatedModel fields = ['field_z'] widgets = { 'field_z': Forms.ModelChoiceField(attrs={'class': 'myclass'}), } labels = { 'field_z': 'Select your Z value here', } And it will work ok but it will ignore its widgets = {} and labels = {}, it will have a default class and the label will be the name of the field ("field_z"). How can I manage widgets and labels when it is not a "regular" field like this last one? -
Showing display values in form built with a loop
I have a simple model form for adding new objects. The template builds the form with a loop, i.e not every field is placed explicitely. The model has a few choice fields. Normally, if you want to see the the display value of the choice field you'd do something like {{ get_myfieldname_display }}. but I cannot use that because I'm using a loop. Here's the view: def tp_new(request): if request.method == 'POST': form = TestPlanForm(request.POST) if form.is_valid(): plan = form.save(commit=False) plan.save() return redirect('tp_detail', pk=plan.pk) else: form = TestPlanForm() return render(request, 'testman/tp_new.html', {'form': form}) Here's the template: ... {% block content %} <form method="POST" class="post-form">{% csrf_token %} <table class="table"> {% for field in form %} <tr><th>{{ field.label_tag }}</th> <td>{{ field }}</td></tr> {% endfor %} </table> <button type="submit" class="mybutton"> Save </button> </form> {% endblock %} ... How can I get it to show the display values for the choice fields? -

Django manage.py runserver command requested resource was not found on this server error
I have just today started working with django. I tried executing the run server command but I keep encountering the page not found error. I have been trying to debug the problem for almost an hour now. Project rms > myrms (app) I have browsed lots of page not found errors questions and their solutions here but none answer the question i have satisfactorily view.py from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("Hello,World.

Multiple link in cell with LinkColumn - Django-table2
I am on different case that this post "django-tables2 linkcolumn multiple items in the same cell" In this case the number of link is defined. In my case, i will generate the link cell with a list of value. apps.py for subject in list_of_subject: study_name_list = subject["study_name_list"] data_studies.append({ 'subject': subject 'study_name': ", ".join(study_name_list), }) table_studies = StudiesTable(data=data_studies) tables.py class StudiesTable(tables.Table): """ StudiesTable class """ study_name = tables.LinkColumn('study_wiki', args=[A('study_name')], verbose_name='Study') subject = tables.Column(verbose_name='Subject') class Meta: """ Meta class """ attrs = {'class': 'table table-bordered table-striped table-condensed'} Now I can just make a link for the join string obtained... In example: Subject1 | Study1, Study2 | Subject2 | Study3 | Subject3 | Study1, Study2, Study3 | I want that you can click on Study1 and go the page for Study1 and you can click on Study2 and go the page for Study2. Thanks in advance for any help. -

How can I render strings with certain characters as value of input tag?
I am passing an array of category names to my template and iterating through this to populate the value of checkbox elements. <input id={{"category"|add:escaped_cat_name}} type="checkbox" name="category" value={{category_name}}> Some of my category names contain spaces and ampersands but Django ignores these so "Fun & Gaming" becomes "Fun": category_name: Fun & Gaming <input id="categoryFun" type="checkbox name="category" value="Fun"> category_name: Business Expenses <input id="categoryBusiness" type="checkbox name="category" value="Business"> In these examples, I would like the interpreted value to read the 'Fun & Gamingand 'Business Expenses If I add a safe tag to the value it renders the value name as "Fun" & gaming, with the second part of the string still outside the value name. I have tried writing a custom tag to deal with this behaviour but it seems as though this is Django's default and I can't figure out how to disable it. Any help with this would be much appreciated. -

C# GetAsync Won't Work with Django Rest Framework
This is the function in my HomeController.cs: async Task<Dictionary<Object, Object>> GetSiteWithID(int ID) { using (HttpClient client = new HttpClient()) { client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Token", "94afa9a8b0804e65a53d335dec230478f69b39c5"); HttpResponseMessage responseMessage = await client.GetAsync("http://localhost:8000/site/1"); responseMessage.EnsureSuccessStatusCode(); return await responseMessage.Content.ReadAsAsync<Dictionary<Object, Object>>(); } } The problem is it's sending the header as "Authorization: Token 94afa9a8b0804e65a53d335dec230478f69b39c5" correctly but Django Rest Framework doesn't get it. Anything else I need to send because if I test with Postman, it works but it is also sending other stuff which I don't know if it's necessary.
