Creating a rating system scale 1-5 and average rating
enter image description here] This is in python with Django and using SQL as database. I am new to this language. I am having issues with creating the average rating for books.

How to associate an existing user with multiple social accounts (different emails)? [DRF_SOCIAL_OAUTH2]
I'm trying to associate user with multiple social accounts in Django Rest Framework. After user login, user can associate with social accounts (it doesn't matter same email or different email). Now I am using the library drf-social-oauth2. I have done signIn/singUp part. According to Social_Auth_Pipeline, I added this code to associate user SOCIAL_AUTH_PIPELINE = ( 'social_core.pipeline.social_auth.social_details', 'social_core.pipeline.social_auth.social_uid', 'social_core.pipeline.social_auth.auth_allowed', 'social_core.pipeline.social_auth.social_user', 'social_core.pipeline.user.get_username', 'social_core.pipeline.social_auth.associate_by_email', 'social_core.pipeline.user.create_user', 'social_core.pipeline.social_auth.associate_user', 'social_core.pipeline.social_auth.load_extra_data', 'social_core.pipeline.user.user_details', ) The endpoint "http://localhost:8000/auth/convert-token" can handle the singin/singup using social auth.(eg. Facebook, Google) social_core.pipeline.social_auth.associate_by_email managed to associate the user if same email. My Question is How can I connect/associate Social Accounts (* different email/same email) with current login user using drf_social_oauth2? Do I need to add field in user table to associate? OR Do I need to add something to setting.py?... Please advise me. Thank you. -

Group Session in Django Channels
I'm looking for a solution where I want to create a group with n number of users and let them-users join the group. and then finally, delete this group once the work is complete. (the creator of the group can delete this or when everyone from the group disconnects). I have been thinking to design this for the last 3-4 days but I'm not able to. I'm building the transcriber app and this group is to maintain sessions on each topic. For every new topic/scenario, a new group/session is required. The question is - How and when should I delete the group? Suppose I created a group and then everyone joins, I can maintain a database and delete this group when everyone disconnects from this group, somehow I don't think this to be the best option Can anyone guide me to design the best possible option? Will provide more details if required. -
Django Web Application - Monitor local folder and import csv files to database
I have this Django web application project that needs to be hosted on a local network. In addition basic CRUD features, the scope requires to continuously monitor a local storage folder (C: or D: or E:) for csv files and import them to the database (Postgresql). I have already written the code for reading the csv files and importing them to the database and moving these csv files to another folder (after importing). What I don't know is where should I put this code and call the function (import_to_db), such that it runs continuously to scan the folder for new csv files? It cannot be a python command line interface. I am not fully conversant with Django REST Framework and not sure if it applies to this scope, since the csv files will be made available in a local folder. Any tips or references to examples/libraries would help. Code to Import: def get_files(): csv_files = [] for file in os.listdir(os.getcwd()): if file.endswith('.csv'): csv_files.append(file) return csv_files def move_files_to_folder(csv_files, destination): try: os.mkdir("BackupFiles") except: print('BackupFiles Directory Already Exists') finally: for file in csv_files: shutil.move(file, destination) os.chdir(destination) return csv_files def import_to_db(): csv_files = get_files() engine = create_engine( url="postgresql://{0}:{1}@{2}:{3}/{4}".format(user, password, host, port, database)) for file … -
Overlaping URLs in Django (two applications in one Django project)
I'm making my studying project, called GuitarStore. I have two application in this project - shop and blog. Here is fictional situation: I have that "contacts" page for my team of authors, and another "contacts" page for my sale team. Here's piece ofmy guitarstore/urls.py: urlpatterns = [ path('admin/', admin.site.urls), path('shop/', include('shop.urls')), path('blog/', include('blog.urls')), path('', RedirectView.as_view(url='/shop/', permanent=True)), ] piece of shop/urls.py: path('', views.shop, name='shop'), re_path(r'^section/(?P<id>\d+)$', views.section, name='section'), re_path(r'^product/(?P<pk>\d+)$', views.ProductDetailView.as_view(), name='product'), re_path(r'^manufacturer/(?P<id>\d+)$', views.manufacturer, name='manufacturer'), path('delivery', views.delivery, name='delivery'), path('contacts', views.contacts, name='contacts'), path('search', views.search, name='search'), and piece of blog/urls.py: path('', views.blog, name='blog'), re_path(r'^blog/(?P<month_n_year>\w{7})$', views.blog_filtered, name='blog'), re_path(r'^post/(?P<pk>\d+)$', views.PostDetailView.as_view(), name='post'), path('gallery', views.gallery, name='gallery'), path('about', views.about, name='about'), path('contacts', views.contacts, name='contacts'), path('search', views.search, name='search'), I thought Django would come up with two separate paths like "shop/contacts" and "blog/contacts" but not. I have that piece of html template: <div class="top-nav"> <ul class="cl-effect-1"> <li><a href="{% url 'gallery' %}">Main</a></li> <li><a href="{% url 'about' %}">Abour us</a></li> <li><a href="{% url 'blog' %}">Blog</a></li> <li><a href="{% url 'contacts' %}">Contacts</a></li> </ul> </div> and all I get is "shop/contacts" for the last part of menu.

For-looping three columns per row in Django template
I'm trying to retrieve data from the database and render it in rows of three columns. I've tried as many methods as I could find, finally it seemed to be rendering with this code: <div class='container'> <div class="row"> {% for category in categories %} {% if not forloop.counter0|divisibleby:"3" %} <div class="col-6 col-md-4"> <h3>{{category.category_name}}</h3> {% for page in category.page_set.all %} <p>{{page.page_title}}</p> {% endfor %} </div> {% else %} <div class="row"> <div class="col-6 col-md-4"> <h3>{{category.category_name}}</h3> {% for page in category.page_set.all %} <p>{{page.page_title}}</p> {% endfor %} </div> {% endif %} {% endfor %} </div> It renders the elements in three columns but the columns are not aligned, and when checking the HTML, the 'row' class is the same for all the rows (giving it an id and checking by CSS), so I guess there's something I'm doing wrong. I'd like to get an output like: Category1 - Category2 - Category3 Category4 - Category5 - Category6 With the 'page' objects of each category underneath. The data is rendering OK, the view is simple (just getting all the Category objects). I just need this kind of data rendering in different rows of 3 columns. I've tried the divisibleby method, but I guess I'm still missing … -

Whats the process for taking a python function and transferring it to Django output?
I'm experimenting with Django, and had a few questions about how python functions are translated into Django outputs. Firstly, is it correct to use Http Responses to generate Django ouptut from python functions? For example, if I have a Hello world function that returns the string Hello world, is it as simple as creating another function within my views.py, and simply return an Http response of HelloWorld()? Is there a different way in which developers conduct this transition from python function to Django? Thanks. def HelloWorld(): return "Hello World" def test(request): return HttpResponse(HelloWorld()) -

Alternative to eval for use in equations [duplicate]
I am creating a Django application that stores an equation with variables that needs to be calculated in the backend. i.e. the user would store the following as a string: {rower_weight}/({rower_time})^3 where rower_weight ad rower_time are variables. Then, in the backend (upon receiving new data) would store a calculated field based on the formula. I considered using eval or f-strings, however would be unsafe with user input. What would be the best alternative that would allow for unsafe user input to be used? Thanks! -
