React: how to pass a string into a body request
I have this method: export const createProject = async (project) => { fetch(`/api/projects/new/`, { method: "POST", headers: { 'Content-Type': 'application/json' }, body: { 'name': project } }) } which calls a django backend that creates a new project with the given name. The problem is that when the api is called, django outputs BadRequest /api/projects/new/ The backend works for sure, as I tested it with postman. What is wrong with the request made by the front end? -
dj-rest-auth sending invalid password rest links
In my Django Rest Framework, the users request to reset the password and when the email is received everytime the link is clicked it shows a message Password reset unsuccessful The password reset link was invalid, possibly because it has already been used. Please request a new password reset. here is what I have tried API urls.py app_name = 'api' router = routers.DefaultRouter() router.register(r'users', UserViewSet, basename='user') urlpatterns = [ path('', include(router.urls)), path('dj-rest-auth/', include('dj_rest_auth.urls')), path('dj-rest-auth/registration/', include('dj_rest_auth.registration.urls')), path('token/', TokenObtainPairView.as_view(), name='token_obtain_pair'), path('token/refresh/', TokenRefreshView.as_view(), name='token_refresh'), # path('password_reset/',PasswordResetView.as_view(), name='password_reset'), # path('password_reset_confirm/<uidb64>/<token>/', PasswordResetConfirmView.as_view(), name='password_reset_confirm'), ] here is the users app urls.py if required: app_name = 'users' urlpatterns = [ path('password-reset/', auth_views.PasswordResetView.as_view(template_name='users/password_reset.html', success_url=reverse_lazy('users:password_reset_done')), name='password_reset'), path('password-reset/done/', auth_views.PasswordResetDoneView.as_view(template_name='users/password_reset_done.html'),name='password_reset_done'), path('password-reset-confirm/<uidb64>/<token>/',auth_views.PasswordResetConfirmView.as_view(template_name='users/password_reset_confirm.html',success_url=reverse_lazy('users:password_reset_done'),post_reset_login=True),name='password_reset_confirm',), path('password-reset-complete/', auth_views.PasswordResetCompleteView.as_view(template_name='users/password_reset_complete.html'),name='password_reset_complete'), ] My question is: Why do I keep receiving invalid links and how can I fix it? In different questions I got answers to add the commented paths but still did not work. Any suggestions on how to fix it ? -

Trying to restric a queryset in Django base on foreign key relationship
I am trying to make a form in Django that gives the user a limited selection based on a foreign key. To be more exact, the form has 2 fields, a ModelChoiceField and a simple text field.

So the goal is to limit the ModelChoiceField to only allow the currently logged-in user to add riddles to just their own rooms. forms.py: from django import forms from .models import Project, Riddle class ProjectForm(forms.ModelForm): class Meta: model = Project fields = ['title', 'max_players', 'has_actor', 'scenario'] class RiddleForm(forms.ModelForm): project = forms.ModelChoiceField(queryset=Project.objects.all(), empty_label=None, widget=forms.Select(attrs={'class': 'form-control'}), label='Project') class Meta: model = Riddle fields = ['project','description'] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['project'].queryset = Project.objects.all() self.fields['project'].label_from_instance = lambda obj: obj.title models.py: from django.db import models from django.contrib.auth import get_user_model from django.urls import reverse User = get_user_model() class Project(models.Model): title = models.CharField(max_length=255, unique=True) max_players = models.PositiveIntegerField(default=0) has_actor = models.BooleanField(default=False) scenario = models.TextField(blank=True, null=True) #number_of_riddles = models.PositiveIntegerField(default=0) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='rooms') def get_absolute_url(self): return reverse( "rooms:project_list", kwargs={ "username": self.user.username, #"pk": self.pk } ) class Riddle(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE) description = models.TextField() urls.py: from django.urls import path from .views import … -

Convert a Pandas's dataframe to a Django QuerySet
I have a model called Job, in this model I store both the original and duplicated jobs. In addition, I have another model called JobStatistics which stores all statistics of both original and duplicated jobs. I want to group the statistics of the duplicated jobs and added them to the statistics of their original jobs. and return only the original jobs with all statistics. suppose a job with the id of id=10001 that has 2 clicks. this job has 3 duplicates, each has 2,4,8 clicks respectively. the result should be job_id clicks 10001 16 one approach is to convert the QuerySet to a Pandas's datafarme and perform and the grouping in the dataframe. but the problem with this approach is that i couldn't find a proper way to convert a dataframe back to a QuerySet. Why I cannot simply return the dataframe, well because I cannot paginate it with a serialzer. What would be a proper way to handle a situation like this? thank you. # models.py class Job(models.Model): title = models.TextField(_("Job Title")) original_job = models.ForeignKey('self',on_delete=models.CASCADE, null=True, blank=True) ... class JobStatistics(models.Model): job = models.ForeignKey("jobs.Job", verbose_name=_("Metric Job") spend = models.FloatField(_("Spend"), default=0) clicks = models.IntegerField(_("Job Clicks"), default=0) impressions = models.IntegerField(_("Job Impressions"), default=0) … -

GET /css/styles.css HTTP/1.1" 404 3609 Python
Im developing a website on python and I found a theme that I like on the internet. It includes the index.html, css folder, js folder and the images. Like in other projects I copies all of the data into the templates folder in my project. I replaced my base.html with this new index.html. The problem is that Django can't find the css and js folders that are being references in the html. I have read some post about this, and everybody mentions taking the index.html outside of templates (doesn't work) or using a static folder to store my css and js files (doesn't work. Can someone give me some clues? thank you!! Project mysite templates assets css js index.html -
Why am I able to insert invalid data into database?
This is my models.py file: from django.db import models # Create your models here. class FxRates(models.Model): business_date = models.DateField() country = models.CharField(max_length=1000) currency_code = models.CharField(max_length=3) exchange_rate = models.FloatField() class Meta: db_table = "FxRates" Using the "migrate" command I am able to create the FxRates database table in the db.sqlite3. Now if I use Pandas to insert data into this database, no errors are thrown if for this line in my data.csv file: 24/01/2023,Bangladesh,BDT,ERR! Shouldn't this have been impossible to insert, considering ERR! is not a number? The Pandas commands I use are: df = pandas.read_csv("/home/data.csv") database_path = "<path_to_db.sqlite3>" connection = sqlite3.connect(database_path) df.to_sql("FxRates", connection, if_exists= "append", index=False) This inserts all the data fine, but why does it let invalid data be inserted? -
django built-in class based view - Where is self.object from?
In the following code, I don't understand something. class SingleObjectMixin(ContextMixin): """ Provide the ability to retrieve a single object for further manipulation.

I would like to figure out where the attribute `object' is created from. -
How to make elided pagination work in django-tables2
I am trying to use django-tables2 v2.5.2 to render a table of products. Pagination renders correctly, it basically looks like: ['prev',1,2,3,4,5,'...',18,'next'] each button is tag with href='?page=x' and after click it updates url with the page parameter but ellpsis button ('...') has href='#' and obviously does nothing when clicked on. Other pages buttons works fine. Do you have any idea how to setup django and/or django-tables2 to make elided pagination work? I am trying to setup simple table with products. I am using function view and RequestConfig, like this: views.py def product_list(request: HttpRequest): all_items = Product.objects.all().order_by("-publish_date") product_filter = ProductFilter(request.GET, queryset=all_items) table = ProductTable(product_filter.qs) RequestConfig(request, paginate={"per_page": 5}).configure(table) return render( request, "product/product_list.html", {"table": table, "filter": product_filter} ) and my tables.py code looks like this: class ProductTable(tables.Table): image_url = ImageColumn(verbose_name="Image") publish_date = tables.DateColumn(format="d M Y", order_by=["publish_date"]) user = tables.Column(verbose_name="Verified by") title = tables.Column(verbose_name="Product") class Meta: model = Product template_name = "django_tables2/bootstrap.html" sequence = ("title", "producer", "user", "status", "publish_date", "image_url") exclude = ("id", "image_url") filterset_class = ProductFilter I tried to read documentation to django-tables2 and django framework but I think I must be missing something. I am expecting the ellipsis button in pagination to load missing page range, so I guess it needs to … -
