Integrating Django and Socket Communication in a Kivy Chat Application
I've developed a chat application using Kivy. Within the application, the server and client establish communication via pythons built-in socket. While it functions adequately, I'm considering incorporating Django on the server side. Navigating through various libraries like pythons built-in socket, Django WebSocket, and websockets has left me somewhat perplexed. I would greatly appreciate your assistance in clarifying at least one of the following queries: 1- Could you elucidate the distinctions between pythons built-in socket, socketio, and websockets in Django, as well as the websockets library in Python? 2- Is it feasible to employ different libraries on the client and server sides, such as using pythons built-in socket (or websockets) on the client side and Django WebSocket on the server side? 3- Does Django Channels offer support for Python's native socket, rather than relying exclusively on channel websockets? 4- Is it plausible to integrate Django into a Python chat application centered around pyhon socket, leveraging its functionalities for user authentication, database management, and static content handling in conjunction with real-time communication? -

Is there a way to 'concatenate' a raw sitemap.xml with the generated in django sitemaps?
Django has a built in sitemaps app that create a sitemap.xml, but I need to integrate with another django project that has it's own sitemap.xml. So, the idea it's to make a call to https:another-django-project/sitemap.xml and with that xml 'append' to my django project sitemap.xml and use that as sitemap. There are 2 projects, in different containers, works like one site(one Web, one Wagtail) mysite.com. So, in mysite.com/sitemap.xml should return all info from both I've tried to implement the class WebSitemap(DjangoSitemap): and override something like 'generate_xml()' so I could make a http call to the another application and append the xml, but that doesn't exist. I've tried to make my own view that calls the django sitemaps programmatically, make a call to the another application xml, concatenate and return. doesn't look a good approach. how can I do that? -
VSCode, Django and javascript: Why does VSCode indicate an error when I use {{ }}?
I have the following code that works in my html file: {% for stocks_and_pair_data in stocks_and_pair_data_list %} <script> var ctxClose = document.getElementById('ChartOfClosePrices{{ forloop.counter }}'); new Chart(ctxClose, { type: 'line', data: { labels: {{stocks_and_pair_data.dates|safe}}, datasets: [{ label: '{{ stocks_and_pair_data.stock1_name|safe }}', data: {{stocks_and_pair_data.stock1_close_prices|safe}} },{ label: '{{ stocks_and_pair_data.stock2_name|safe }}', data: {{stocks_and_pair_data.stock2_close_prices|safe}} }] } }); </script> {% endfor %} But VSCode indicates the error "Property assignment expected" at 'labels' line and at both 'data' lines, which are where I use double {{ }} without quotes. I can't use quotes there because these are lists, not strings. Am I doing it wrong, despite of the code working? What should I do to correct it? -
django on update modelform not presenting stored value as selected
I have an uninteresting modelform. One of the model fields, occupation, is a foreignkey to a table containing a long, long list of options. The problem is for update, the rendered form, which is rendered via crispy, does not set focus to the stored value (mark it as the selected option in the <select><option...> code). Instead, it shows the empty choice. I see the initial value does point to the id of the database's record. To make this a little more "interesting," I want to change occupation.to_field_name to occupation.code (a charfield). I've been futzing with the form's init as given below. I can convert the option values to the form I want, but I cannot get the form to present the stored value as selected (and present as the field's selected value). How do I do this? Do I have to do it via JS or am I doing something wrong with the form? Thanks. class Meta: model = TutorOptionalServiceAndDemographics fields = ['highest_degree', 'country_of_birth', 'immigrant', 'us_citizen', 'employment_status_at_enrollment', 'occupation', 'employer_name', 'referral', ] labels = { 'highest_degree': 'Highest degree/diploma earned', 'us_citizen': 'US Citizen:', 'immigrant': 'Immigrant:', 'country_of_birth': 'Country of Birth:', 'employment_status_at_enrollment': 'Employment status at time of registration:', 'occupation': 'Occupation:', 'employer_name': 'Employer Name:', 'referral': … -

How to implement in-built scheduled celery tasks in third party packages
I have looked at the celery codebase to get an idea of implementing an in-built scheduled task but I am not sure whether that's the way to go about it for my case. I have a third-party package (meant to be used in Django projects) that needs to have a scheduled in-built celery task, just as backend_cleanup is built in celery. The developer using the package needs to be able to disable the task or update the crontab schedule using some Django settings. This is what I have so far in the package code based on what I saw in the docs: # tasks.py app = Celery() @shared_task def do_stuff(): # do some stuff that will access the database pass @app.on_after_configure.connect def setup_periodic_tasks(sender, **kwargs): okay_to_run = getattr(settings, 'OKAY_TO_RUN', False) if okay_to_run: default_schedule = crontab(0, 0, day_of_month='2') schedule = getattr(settings, 'OKAY_TO_RUN_SCHEDULE', None) if schedule is None: sender.add_periodic_task(default_schedule, do_stuff.s()) else: sender.add_periodic_task(crontab(**schedule), do_stuff.s()) I see celery detects the task but it does not schedule it. What could be wrong and is there a better approach to this? -
How to use design Django APIs using Djoser with multiple users?
I am new to Django and Djoser. I am currently planning to implement a job portal management system. I have 3 stakeholders: companies, recruiters and applicants. So, my company profile is created using official company email and it is used to invite emails that can create an account in my web application as an recruiter, and it will be able to track all the records of the recruiters my recruiter will be able to receive an invitation email that directs them to create an recruiter account, and check on their jobs my applicants will have to create their account on their own In this case while implementing Djoser, I am planning to design the API like the following: # for applicants path('api/', include('djoser.urls')), path('api/', include('djoser.urls.jwt')), # for companies path('api/companies/', include('djoser.urls')), path('api/companies/', include('djoser.urls.jwt')), # for recruiters path('api/recruiters/', include('djoser.urls')), path('api/recruiters/', include('djoser.urls.jwt')), Am I on the right track while designing it like this? Much appreciated if you could describe the pros and cons of doing so (still very new to this). Discussions and feedbacks on how the way I design the APIs. -

Designing a Generic List Manager Library with User Permissions in Django/Python
I'm currently in the process of developing a versatile and reusable Generic List Manager Library for applications built with Django/Python. This library aims to provide a generic solution for creating and managing lists of various entities Here are the key requirements for this generic library: User-List Association: A list should be associated with one or multiple users. User Permissions: Users linked to a list should have different permissions such as read, write, and share rights. Abstract Lists: Lists should be abstract and capable of linking to a single model, with a field defining the primary model it references. Multiple Models: It should be possible for two different lists to point to different models. I am seeking advice on what are some suitable design patterns for doing this. I am thinking of using a combination between Repository Pattern && Mediator Pattern to implement this, but I would love to hear different opinion or takes into this. -
I am unable to update value of lifecycle stage using hubspot api
I am using hubspot api to update the value of lifecycle stage of a contact. The value can be changed to any other value in the hubspot crm. But when I am using the api to do so, I can change the value of the lifecycle stage to a higher stage say, from a Subscriber to Lead, as Subscriber is lower in rank than Lead. But when I try to change the value from Lead to Subscriber using the api, it doesn't do so. There is no error too. I am not sure if it is a bug with the api or there is some restriction to do so.

Django Permission per Database Object
I have an architectural question regarding Djangos permission model. I do have a Database Model which hold companies, and each company can have multiple projects. Users should be able to only see companies that they are assigned to and only see projects which they are assigned to. I am now confused whether I should have a Many2Many Relation in the companies and projects which holds the allowed users and then check them on access through the permission system? Or create a new permission for each company, add this permission to the company and/or project and then give the users these permissions? Somehow I think solution 1. gets me into problems in the long run when querying all projects one user should see. But solutions 2 got me stuck since there is no permission field in the models, so I always have to cast string field to permission and I will generate a huge amount of permissions overall. Maybe I am completely overthinking this? What would be the best approach to per Database-Entry permissions? Thanks and Best Regards -
