Class 'Item' has no 'Objects' memberpylint(no-member)
I'm trying to import the model into my views but somehow it's giving me an error "Class 'Item' has no 'Objects' memberpylint(no-member)". I don't understand why? views.py from django.shortcuts import render from .models import Item # def products(request): # context = { # 'items': Item.objects.all() # } # return render(request, "products.html", context) def item_list(request): context = { 'items': Item.Objects.all() } return render(request, "home-page.html", context) def checkout(request): return render(request, "checkout.html") here's my model for that from django.conf import settings from django.db import models CATEGORY_CHOICES = ( ('S', 'Shirt'), ('SW', 'Sportswear'), ('OW', 'Outwear') ) LABEL_CHOICES = ( ('P', 'primary'), ('S', 'secondary'), ('D', 'danger') ) class Item(models.Model): title = models.CharField(max_length = 100) price = models.FloatField() category = models.CharField(choices=CATEGORY_CHOICES, max_length=2) label = models.CharField(choices=LABEL_CHOICES, max_length=1) def _str_(self): return self.title class OrderItem(models.Model): item = models.ForeignKey(Item, on_delete=models.CASCADE) title = models.CharField(max_length = 100) def _str_(self): return self.title class Order(models.Model): title = models.CharField(max_length = 100) items = models.ManyToManyField(OrderItem) start_date = models.DateTimeField(auto_now_add=True) ordered_date = models.DateTimeField() ordered = models.BooleanField(default=False) def _str_(self): return self.title Can anyone tell me what's it I'm doing wrong? Same with the product function when I try to call the Item it's giving me the same error. That's why I commented out. -
Overriding Django admin inlines formset will not save more than 1 row
I have a straight forward admin.ModelAdmin class with an inlines, of which I am overriding the form and formsets with a forms.Model and BaseInlineFormset to add a custom field. I have a custom jQuery script that gets loaded in and whenever a machine is picked from the select2 drop-down it runs an AJAX query to the REST API and grabs the items based on a foreign key value and populates the CleaningEntryInline with information. However, upon saving it is only posting a single record to the database. class CleaningEntryInline(admin.TabularInline): model = CleaningEntry form = CleaningEntryForm formset = CleaningEntryFormSet extra = 0 raw_id_fields = ['cleaning_item'] fieldsets = [ (None,{'fields':[('cleaning_item','cleaning_action', 'checked', 'na', 'notes')]}) ] template = 'admin/quality/cleaningentry/edit_inline/tabular_actions.html' class CleaningLogAdmin(admin.ModelAdmin): ####Save model function override to make and save QC Lab user and make uneditable. def save_model(self, request, obj, form, change): obj.lab_user = request.user.username obj.save() list_display = ['machine_used','get_product_info','lot_num','start_time','lab_user'] list_filter = ['machine_used'] readonly_fields = ['lab_user', 'cleaning_users'] search_fields = ['machine_cleaned', 'lot_num', 'recipe_cleaned__recipe_name__item_code', 'lab_user'] autocomplete_fields = ['machine_used','recipe_cleaned'] fieldsets = [ ('Cleaning Info',{'fields':[('machine_used', 'recipe_cleaned', 'lot_num')]}), (None,{'fields':[('start_time')]}), (None,{'fields':[('clean_time', 'lab_user')]}) ] inlines = [CleaningUserInline, CleaningEntryInline] change_list_template = 'admin/quality/cleaninglog/change_list.html' list_per_page = 25 form = CleaningEntryForm class Media: js = ( 'admin/js/vendor/jquery/jquery.min.js', 'admin/js/jquery.init.js', 'admin/js/list_filter_collaspe.js', 'admin/js/equipaction_filter.js', ) css = {'all':( 'admin/css/vendor/select2/select2.css', ) } … -
ImportError: No module named. Worker failed to boot

Using foreign keys on the same model, but on two different fields
If this question is stupid I'm sorry, but I couldn't really find anything useful on Google. So I have a model made up of two fields. I want to create a model with some other fields, but two of them should be the ones from the previous one. Is there any way to obtain this? Code: from django.db import models from django.contrib.auth.models import User from datetime import date # Create your models here. class CORMeserii(models.Model): CodCOR = models.CharField(max_length=25, primary_key=True, unique=True) MeserieCor = models.CharField(max_length=50, unique=True) class Oferta(models.Model): solicitant = models.ForeignKey(User, on_delete=models.CASCADE) cor = models.ForeignKey(CORMeserii, max_length=25, on_delete=models.CASCADE) meserie = models.ForeignKey(CORMeserii, max_length=50, to_field='MeserieCor', on_delete=models.CASCADE) dataSolicitare = models.DateField(default=date.today) denumireMeserie = models.CharField(max_length=50) locuri = models.IntegerField() agentEconomic = models.CharField(max_length=50) adresa = models.CharField(max_length=150) dataExpirare = models.DateField() experientaSolicitata = models.CharField(max_length=200) studiiSolicitate = models.CharField(max_length=200) judet = models.CharField(max_length=20) localitate = models.CharField(max_length=25) telefon = models.CharField(max_length=12) emailContact = models.EmailField(max_length=40) rezolvata = models.BooleanField(default=False) def __str__(self): return self.cor I thought this might work, but I get these errors: from django.db import models from django.contrib.auth.models import User from datetime import date from .validators import validate_file_size # Create your models here. class CORMeserii(models.Model): CodCOR = models.CharField(max_length=25, primary_key=True, unique=True) MeserieCor = models.CharField(max_length=50, unique=True) class Oferta(models.Model): solicitant = models.ForeignKey(User, on_delete=models.CASCADE) cor = models.ForeignKey(CORMeserii, max_length=25, on_delete=models.CASCADE) meserie = models.ForeignKey(CORMeserii, … -

Is there a better way to write output of background tasks to the database?
first of all thx for reading. In my project, I have azure-function / azure webjob to do the parsing，analysis of the raw data when it comes to the storage account. The output will be update to database with direct sql command like: sql_update = """UPDATE "PrototypeOne" SET files_amount =%s, used_time = %s where "User_Name" =%s;""" cursor.execute(sql_update,vars) My questions are: 1, is there a smarter way to update the database? can my backend play some role in between? 2, Is there a pub/sub library for such 'script level' application? Background: My backend is django 2.0+, with postgresql as database on azure. -
connect assets uploaded in anonymous mode post login
I am building a web app where user can upload a file in logged out mode but expects the file to be associated with him post login in the same session. The way I have implemented is to attach both a session_key and a User to the model as follows class Asset(Model): id = BigAutoField(primary_key=True) file = FileField(upload_to=get_file_path) submission_time = DateTimeField(auto_now_add=True, blank=False) expiration_time = DateTimeField(default=some_method) session = CharField(max_length=1024) user = ForeignKey( User, on_delete=CASCADE, related_name="%(app_label)s_%(class)s_related", related_query_name="%(app_label)s_%(class)ss", blank=True, null=True) def __str__(self): return self.file.name When the user first uploads the Asset, I capture the same and store it in backend with session_key. Once users confirms his willingness to post this Asset to share with community by doing signup/login, I match the Asset's session key with current session key and updates the user field in the Asset model. Is this the best approach? Does this approach have any security loopholes here? -

Is it safe to use auth_user for regular website users?
I want to create a website where people can post things using accounts. It should also be possible to login with google (or other) OAuth, where I would basicly create an auth_user for them using googles tokens. So is it safe to use djangos preexisting user and group system for regular everyday users of my website by just denoting them without staff or superuser priviledges? Also can I just link the google token to an auth_user and start a session for him that way? Or should I implement my own user and group system? -

Django Rest Framework: Get singular object using the root API
I am trying to set up an API endpoint that returns a singular object.

The issue is the filter function returns a queryset, but I only want a single item. I attempted to use the RetrieveModelMixin but that doesn't run on the endpoint that I want. Retrieve runs on .../api/shopping-cart/id but I want to retrieve on .../api/shopping-cart because the filtering is done via the person who is logged in. Any solutions? -

Using CheckboxSelectMultiple inside a form that uses input from DB related to User using ForeignKey. [See explaination]
I have a model called Level1 which is related to User model using ForeignKey class Level1(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) ans = models.CharField(max_length=1024) IT takes input from user and saves it in DB. I can get all the inputs that are given by the specific user by using user=request.user level1_answers=user.level1_set.all() (IF there is another method, please do share) Now what I want to do is to use these answers from level1 (level1_answers) and use them as an input for the Level2. Where Level 2 is a model same as Level1 with ForeignKey as User and ans except the fact that Instead of taking new answers as input, It uses the answers from level1 and presents the user with Checkboxes from those. class Level2(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) ans = models.CharField(max_length=1024) #I want ans to be presented as CheckboxSelectMultiple using Level1 answers. If user has answered 1,2,3,4,5,6,7 for Level1, I want to show Checkboxes to select from these and save this in DB in table Level2. -

How to use Global python environment instead of virtual on Azure App Service
I have a Django web app deployed on Azure App Service. I have integrated a bash script in it which is required for running some python notebooks for DataBricks. Problem is that when bash script is installing python packages in the virtual environment as expected but DataBricks notebook which it is calling is finding those packages in the global environment. I have tried deactivating the virtual inside bash script but that doesn't work. Is there any way to instruct azure app service to use global python environment instead of creating a virtual environment. Thanks
