Python-Django: How to list what is the specific database used of a specific application
I'm currently handling a existing project and just want to have an enhance on one of its specific application. There is a list of Databases in the settings and currently hard to find what application 1 database use. For example I have 5 Application and in the settings I have 10 Databases. I just want application 1 to be enhance/developed and the rest of the app not included when I migrate. Is there anyway that I just going to list what application 1 database used? So that the listed databases that application 1 use is the only databases that I'm going to include to the settings. Since I just going to have the databases limitedly copy to a dev server not the whole prod server. -
Deploy ML Model GCP / Django at scale, how to manage session?
I have build my model (dump file), but I need to deploy it for some users (maybe 10 for the first time). This is a chatbot, but: Every message linking to the previous message (Hello how can I help you?....I need tips for that.... Ok which tips??...) This is a web app, the first architecture that I think is to use: Flask Rest / FastAPI to deploy model as an API in cloud run (GCP) I'am using Django REST for the web back-end side, so, I would like to call the ML Model rest api in the django part. So, the ideal pattern is every users can access to a dedicated chatbot (ML Model). from fastapi import FastAPI app = FastAPI() MODEL="./model/mdel.dump" ... -
How django drop column in SQLite
Don't be confused. I am not asking how to drop column in Django. My question is what Django actually does to drop a column from a SQLite database. Recently i came across an article that says you can't drop columns in SQLite database. So you have to drop the table and recreate it. And its quite strange that if SQLite doesn't support that then how Django is doing that? Is it doing this? -
Handling multiple GET variables with Django
I have a view template that has multiple forms that can be handled by get data. Such as a search function, a number of entries per page dropdown, and a pagination. I was wondering how I could go about having all of these work together without overwriting the other, for example: www.website.com/account/?entries_per_page=5 This could be the url the user is currently on but lets say they search for "pineapple", I would like for it to goto: www.website.com/account/?entries_per_page=5&search=pineapple instead of, www.website.com/account/?search=pineapple but also we have to keep in mind the page the user is on unless they do a new search: www.website.com/account/?entries_per_page=5&search=pineapple&page=2 or www.website.com/account/?search=pineapple&page=2 I hope this isn't confusing, I really have been stuck on this and have not been able to figure out what to do. -

Django serializing json
I'm building an API using django and I have come across a problem.

Is there anyway to reduce the bitrate of cv2.VideoWriter live camera record video?

How to organize Caching in Django?
I'm trying to figure out how to properly organize caching. There are actually two questions. Is it okay to implement caching like this? Perhaps there is a better option? class PostsListView(ListView): template_name = 'pages/post_list.html' def get_queryset(self): posts_list_qs = cache.get('posts_list_qs') if not posts_list_qs: posts_list_qs = get_all_posts() cache.set('posts_list_qs', posts_list_qs) return posts_list_qs What is the best way to invalidate this cache? What if I have a dozen of views / asynchronous functions, etc that require data from Posts. Just listing all the keys in signals like this? Should be a better way I think...And what if I need to use 'prefetch related'(inner join) for some request to database? I even need to repeat cache.delete(key) in signals for some other models. @receiver(post_save, sender=Post) def post_post_save(sender, instance, created, *args, **kwargs): cache.delete('posts_list_qs') cache.delete('posts_data_for_api_qs') cache.delete('posts_data_for_views_qs') cache.delete('posts_data_for_email_sending_qs') Please, advise me about how to organize work with the cache in the best way!? -
MultiValueDictKeyError varies in localhost and Heroku host
I'm currently learning django and I've created a simple TODO project which has an otp authentication feature. While running the project in localserver otp was generated and stored in the model which is then matched by using if (t.otp == int(request.POST['otp'])): where t is a model object. This works perfectly fine. While I deployed the same in heroku server with DEBUG = True for testing purpose, it is throwing MultiValueDictKeyError in line if (t.otp == int(request.POST['otp'])):. Initially t.opt is set to the value generated and it is reinitialized to 0 once the user enters the correct OTP and registers. Kindly notice the comments in the code that explains the issue a bit more. My views.py goes as (I've removed some elif part that are not required to reduce the number of lines), def regsub(request): if(request.method=="POST"): uname = request.POST['username'] fname = request.POST['fname'] lname = request.POST['lname'] email = str(request.POST['email']) pass1 = request.POST['pass1'] try: **#this tries to get the values pass1 and pass 2 whereas except gets the value otp** if(request.POST['pass1']==request.POST['pass2']): dictpass = { 'username':uname, 'fname':fname, 'lname':lname, 'email':email, 'password':pass1, } the_otp = r.randint(100000,999999) try: t=temp.objects.create(name=uname,otp=the_otp) t.save() except(IntegrityError): return render(request,'register.html',{'flag':True,'msg':"Username already exits!

Accessing attributes on different types of profiles

However my problem raise where I have to deal with a set of Users with different type of profile. Now I have to constantly use conditions every where I need to access attributes on User's profiles.

Through relationship using polymorphic model
I'm trying to use a through relationship between a polymorphic and a non-polymorphic table with the the RankedAthlete model: class ChoiceBlank(PolymorphicModel): pass class ChoiceAthlete(ChoiceBlank): choice = models.ForeignKey('SomeModel', on_delete=models.CASCADE) class BetMultiple(models.Model): answer = models.ManyToManyField('ChoiceBlank', blank=True, through='RankedAthlete') class RankedAthlete(models.Model): choiceAthlete = models.ForeignKey('ChoiceBlank', on_delete=models.CASCADE) bet = models.ForeignKey('BetMultiple', on_delete=models.CASCADE) rank = models.IntegerField() This doesn't work because RankedAthlete expects a ChoiceBlank and a ValueError is raised when I create one.

Django: display many to many relationship through a model in themplate
I have this ManyToMany relationship through an intermediary model: class Group(models.Model): members = models.ManyToManyField(Student, through='NamedMembershipClub') class Membership(models.Model): year = models.IntegerField() user = models.ForeignKey(User, on_delete=models.CASCADE) group = models.ForeignKey(Group, on_delete=models.CASCADE) I'm trying to display members with the year they joined in my template. I read on this post that I should use members_set.all {% for member in object.members_set.all %} <p>{{member.user.first_name}} {{member.year}}</p> {% endfor %} But it doesn't produce any output, the loop is just not entered because the set is empty. I also tried : {% for member in object.members.all %} <p>{{member.first_name}}</p> {% endfor %} Which gives some satisfaction because I can display the user but not the associated data in the Membership model. Is there any way to get the set directly in the template ? Thanks! I'm running Django 3.0. -
