Creating a webclient to send and receive emails
I have to create a webclient to send and receive emails from gmail and outlook accounts. It should be able to run directly in a browser with any setup on the computer. Here are the important details: I have planned to use imaplib and smtp library in python. It will be a django project. I will use react for the frontend. And mondodb to store some data in a database. And aws for deployment. The webclient will be used by approximately 10 people. The webclient will have many functionalities not available in other clients. So my question is, Is it possible to create such webclient or am i missing anything like protocols, security or hardware requirements? You might find this question as not exactly related to programming, but it is important for me to get an answer. As I am new to djando and mongodb, i want to make sure that I don't waste my time trying to create something which is not possible. -

Handling multiple types of users in Django
I am building a django app that will need to have two types of accounts (Merchant and Buyer), not that it matters but just to provide more context, on my sign up page, I have a radio button to let the user choose if they want to register as a Merchant account or as Buyer account, and each account type will have a separate sign in page to login to the website. I was thinking of using this approach. Please ignore discrepancies in the code, it was simplified just for the question. class User(AbstractBaseUser): first_name = models.CharField() last_name = models.CharField() date_joined = models.DateTimeField(auto_now_add=True) is_active = models.BooleanField(default=True) class Merchant(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) email = models.EmailField(unique=True) ph_number = models.CharField() class Buyer(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) email = models.EmailField(unique=True) As you can see each account can have unique fields like the ph_number so I came up with this approach after some research. Question 1 While inheriting AbstractBaseUser I need to have a uniquely identifiable field to assign to USERNAME_FIELD, in my case I don't really have one for the User, so what do I use here? I intend to have two custom authentication back-ends to use the email field from the Merchant … -

How to implement download data option for web app
I am developing a feature to a web app ( dictionary-like app ) - a download option. It means that a user can request to download data ( of certain models ).

Creating a List of forgein keys in django model
I'm trying to make 2 models in Django that are interconnected one called pathways and one called courses. I wrote a Json file, that I was hoping to use load data on, where the tables are set up like this courses: "code": 1964, #primary key "name": "Documentary in the 21st Century", "category": "IHSS", and pathways: "id": 1, #primary key "name": "Arts", "inquiries": [ 1080, 1300, 1170, 1700 ] As you can see I want the model pathways to contain a list of foreign keys pointing to several different courses, but I'm new to Django and can't find anything helpful online. -
Filtering many-to-many in materialized view in Django?
I'm building a Django application which requires creating and filtering a materialized view. I'm having trouble understanding what's the best way to create the materialized view. As an example, I have two tables related with a many-to-many relationship. class Company(models.Model): name = models.CharField(max_length=255) ... class Person(models.Model): name = models.CharField(max_length=255) age = models.PositiveIntegerField() ... places_worked_at = models.ManyToManyField(Company) I'm going to be grouping by persons and would like to implement a materialized view following something like the model below. However, I'm stuck and unsure about how to not only create the materialized view, but how I would store the multiple company ids and names that a person might have in the model. class PersonCompanyMV(models.Model): person_id = models.IntegerField() person_name = models.CharField(max_length=255) person_age = models.PositiveIntegerField() company_ids = ??? company_names = ??? class Meta: managed = False db_table = 'person_company_mv' I'd imagine there's a simple way to implement something like this that allows for easily filtering like PersonCompanyMV.objects.filter(company_id=1)? Any help or links to documentation would be appreciated. -
Django - I don't manage to pass a dataframe or dictionary from views.py to template home.html
Struggling already 5 days with this, appreciate all the help on this . I want to learn how to pull data from database (sqllite) , do some python stuff and pass the result in a dataframe or dictionary from views.py to html template. I'm building django ecommerce webshop with bootstrap template (starting from djecommerce project) . The model 'Item' is a table of products with item.price, item.description, item.etc... in the 'home.html' products cards are constructed with a for loop '{% for item in object_list%} -> card. In this problem , users should search for a product (example 'bike helmet') , after which we pull all the items (Item.objects.all()) , do some python stuff and it should return a dataframe/dictionary/whatever so that I can loop it through in the template. Currently I transform the primary keys back into a list and then do Item.objects.filter(pk=[list of id's]) but I really want to learn to do it properly. I tried so many variations on whatever I have found on the internet so forgive me the current solution below. Thanks already for the feedback and support. I'm sure I'm missing something 'easy' and not understanding it right.. VIEWS.PY ''' class HomeView(ListView): model = Item … -
