Do I need a User Class in my models? Or is there an easy fix to the foreign key?
Made some modification to my code (there is was some mistake) which created a new problem. Pulling the following error message: "insert or update on table "main_productreview" violates foreign key constraint "main_productreview_user_id_bdd4771a_fk_main_user_id" DETAIL: Key (user_id)=(3) is not present in table "main_user"." (I used to have a User class in my models.py which I have removed as registered Users where not moved to Main. Removing the class sorted the problem, but created this one) What I am trying to do: when a user is logged in, the user can leave a review against a specific product. Any idea? Models.py from django.db import models from django.contrib.auth.models import User from decimal import Decimal import locale import logging class Product(models.Model): name = models.CharField('Product Name', max_length=120, null=True) description = models.TextField(blank=True, null=True) price = models.DecimalField(null=True, max_digits=6, decimal_places=3) #venue = models.ForeignKey(Venue, blank=True, related_name="venue", on_delete=models.CASCADE) tasters = models.ManyToManyField(User, blank=True) image_url= models.URLField('Image Web Address', blank=True) product_url = models.URLField('Product Web Address', blank=True) class Meta: db_table='Product' def __str__(self): return str(self.name) RATING=( (1,'1'), (2,'2'), (3,'3'), (4,'4'), (5,'5'), ) class ProductReview(models.Model): user=models.ForeignKey(User, on_delete=models.CASCADE) product=models.ForeignKey(Product,related_name="comments", on_delete=models.CASCADE) review_text=models.TextField(max_length=250) review_rating=models.IntegerField(choices=RATING,max_length=150, default=0) date_added = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now_add=True) def __str__(self): return '%s - %s - %s'%(self.user, self.product, self.date_added) Views.py from django.shortcuts import render, redirect from django.http import … -
Django Form/Models: Adding Row Data To Existing Model Instance Via Form
Description of Database Hello so my problem is that I have a Database with three models: Beacon: Which collects data about hosts that ping back data to it. Command_Node: Which collects commands to be executed by the host in question via a form submitted by the website user. Executed_Commands: Which will collect any Commands contained within a Command_Node when they are collected through a query by a connecting machine via a function to be implemented, it will also delete the Commands in a Command_Node as they are now previous commands. (To be implemented) Problem I want to add multiple commands to a single instance of a Command_Node. Via a form, which allows me to select which host I want to give commands to, and which allows me to select which commands to issue to which host. It should then adds those commands into the current_commands column of that Command_Node as a new row, in the selected Command_Node instance. However I don't know how to do this. I don't need to edit existing commands, I don't need to create a new Command_Node instance as the present code does. I just need to add more rows to existing instances. Any ideas on … -

Architecture clarification for Warehouse Django application
everyone, I've started implementing my next project under the Warehouse title :) And actually, I am stuck, again. I guess I've made things too complicated and I don't know how to get out of it. So basic assumptions of Warehouse application: We have a few products You take the goods to the warehouse - the order consists of multiple products. You must know the purchase price and qty for each of them. Some model which will store information about current stock status. I guess it will be Singleton? You sell products from Warehouse - order consists of products sell price, product qty Ok, It seems to me all the above are basic assumptions, below is what I wrote to reach my target but I am pretty sure it doesn't work as is intended. I will be very grateful for any tips and tricks and clarification on architecture. class OrderIn(models.Model): # Standard fields last_updated = models.DateTimeField(auto_now=True, editable=False) ordered = models.DateField(auto_now_add=True, editable=True) received = models.DateField(auto_now_add=True, editable=True) class OrderOut(models.Model): # completed = models.BooleanField(default=False) # Standard fields last_updated = models.DateTimeField(auto_now=True, editable=False) ordered = models.DateTimeField(auto_now_add=True, editable=True) class MiddleOrder(models.Model): order_in = models.ForeignKey(OrderIn, on_delete=models.CASCADE, blank=True, null=True) order_out = models.ForeignKey(OrderOut, on_delete=models.CASCADE, blank=True, null=True) def save(self, *args, **kwargs): super(MiddleOrder, … -

Django & POSTMARK API Templates
I'm trying to send a receipt template using POSTMARK API from my Django application but I'm struggling with retrieving multiple items under receipt details. I'm converting my query of items within an order to a list, then from the list, we are serializing it to JSON. Here is the output I get with the JSON with products when I run print: [{'product__name': 'Pokemon 25th Anniversary', 'quanity': 1, 'product__point_price': 100.0}] The serialization all looks correct however if you have multiple items, this becomes an issue. If you look down at my code under receipt details you will see I had to specify [0] before specifying the key name. How do I do this without specifying [0] so I can get all items? Here is my code : VIEW @login_required def checkoutcomplete(request): customer = request.user order = Order.objects.get(customer= customer , complete = False, ) favorites = Favorite.objects.filter(customer = customer.id) today_date = datetime.datetime.today() today_date_strf = datetime.datetime.strftime(today_date,"%m/%d/%Y" ) items = order.orderitem_set.all() data = list(items.values("product__name","quanity","product__point_price")) save_json = json.dumps(data, indent = 2) my_cart_json = json.loads(save_json) #POST MARK API url = "https://api.postmarkapp.com/email/withTemplate" payload = json.dumps({ "From": "", "To": "", "TemplateId": 28132290, "TemplateModel": { "counselor_name": "Fellow Counselor", "student_name": student.student_name, "receipt_id": str(order.transaction_id), "date": today_date_strf, "points": order.get_cart_total, "receipt_details": [ { … -

Django User Model (Employee and Customer)
I am currently working on a mobile app delivery system which involves two types of users: "Employee" and "Customer". Each type of user would have different views and permissions within the app. In addition, each type of user would their own "profile", if you will. The employee's profile purpose is mostly just to designate company roles. The customer's profile is mostly used to save an address for delivery. I am trying to get some opinions on what the best practice to achieve something like this would be. I can't decide if its better to use AbstractBaseUser or AbstractUser. Below is a visual of the models I am wanting to create along with their relationship: Below is the the user/models.py file that I mocked up: class UserTypes(models.Model): type = models.CharField(max_length=100) def __str__(self): return self.type class User(AbstractBaseUser): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) email = models.EmailField() phone_number = models.CharField(max_length=20) is_employee = models.BooleanField(default=False) is_customer = models.BooleanField(default=False) def __str__(self): return f'{self.first_name} {self.last_name}' # if user.is_employee == True class EmployeeProfile(models.Model): EMPLOYEE_ROLES = ( ('Driver', 'driver'), ('Production', 'production'), ('Manager', 'manager') ) user = models.OneToOneField(User, on_delete=models.CASCADE) role = models.CharField(max_length=12, choices=EMPLOYEE_ROLES) def __str__(self): return self.user # if user.is_customer == True class CustomerProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) company = … -

How to create a registration form in Django that will recognise when password and confirm password don't match
I am trying to build a registration form for a user on a webpage using python and the Django framework. The form works fine and registers a user if all the fields are valid and Django has built in error messages if fields are left blank etc which work fine. However, I am trying to add my own error for if the 'password' and 'confirm password' fields don't match. If they don't match I get an error stating: 'The view main.views.register didn't return an HttpResponse object. It returned None instead.' My question is how would I successfully return the registration page with the error displayed to the user?

I forked this Tutorial https://github.com/TwilioDevEd/automated-survey-django and am trying to get it to run locally. The current behavior is that, I send a text to the Twilio number and then it correctly texts me the first question of the survey. However, then when I text back, I don't get a response (should be the 2nd question of the survey) and I see a 500 error in Django. I can see that the second text message is being received by Django and, from the following function, it prints HELLO. However, it doesn't make it to YEP, so it appears to be erroring on answering_question = request.session.get('answering_question_id'), which seems like it is a problem with the session. I can see that there is a new session in the Django_session table created from my first text. I'm stuck on what is going wrong. request.session['answering_question_id'] is being set elsewhere in the code, but, my understanding, is if wasn't set, then answering_question would just be false, not an error. I'm stuck - any thoughts? def redirects_twilio_request_to_proper_endpoint(request): print("HELLO") answering_question = request.session.get('answering_question_id') print("YEP") if not answering_question: print('1') first_survey = Survey.objects.first() redirect_url = reverse('survey', kwargs={'survey_id': first_survey.id}) else: print('2') question = Question.objects.get(id=answering_question) redirect_url = reverse('save_response', kwargs={'survey_id': question.survey.id, 'question_id': question.id}) return …
