Django: creating a model from a raw sql query that performs a Join on 2 tables
So I have a mysql database that we use for reporting. We are trying to create an API that queries this database in order to find clients that deposit over a certain ammount: query looks like this: SELECT t.`LOGIN`,SUM(t.PROFIT) AS total_deposits,u.`phone` FROM mt4_trades t join mt4_users u on t.LOGIN = u.LOGIN where t.CMD=6 and t.COMMENT like 'DP%' and u.`group` like 'FX%' group by t.`LOGIN` having sum(t.PROFIT)>10000; I performed python manage.py inspectdb in order to create a model with those fields. The problem is those fields are coming from different tables. This is what my model looks like: from django.db import models # Create your models here. class BigDeposit(models.Model): login = models.IntegerField(db_column='LOGIN', primary_key=True) # Field name made lowercase. group = models.CharField(db_column='GROUP', max_length=16) # Field name made lowercase. profit = models.FloatField(db_column='PROFIT') # Field name made lowercase. phone = models.CharField(db_column='PHONE', max_length=32) # Field name made lowercase. class Meta: managed = False db_table = '?????' 1st question: what am I supposed to put in the db_table field in such a case. 2nd question: how can I perform a raw query to create a 'BigDeposit' queryset from this? Thank you -
How to using post_save to multiple model / table in django
I've a trouble to save many fields to multiple model/table. I wanna save fields name and email to UserDashboard and CustomUser. Basically my code comes through looking like this: class UserDashboard(models.model): name = models.CharField(unique=True, max_length=80) email = models.CharField(max_length=254) role = models.CharField(max_length=1, blank=True, null=True) class Meta: db_table = 'user_dashboard' class CustomUser(models.model): name = models.CharField(unique=True, max_length=80) email = models.CharField(max_length=254) birthday = models.DateField(blank=True, null=True) sex = models.CharField(max_length=1, blank=True, null=True) password = models.TextField(blank=True, null=True) class Meta: db_table = 'user' def add_user_dashboard(request): if request.method == 'POST': formRegis = UserDashboardForm(request.POST) if formRegis.is_valid(): //save to UserDashboard model userDashboard = formRegis.save(commit=False) userDashboard.name = formRegis.cleaned_data['name'] userDashboard.email = formRegis.cleaned_data['email'] userDashboard.password = random_pass(8) userDashboard.save() //save to CustomUser model customUser.name = userDashboard.name customUser.email= userDashboard.email customUser.role = formRegis.cleaned_data['role'] customUser.save() else: return HttpResponse(formRegis.errors) else: formRegis = UserDashboardForm() data = { 'formRegis' : formRegis } return render_view(request, 'user_dashboard/registerUserDashboard.html', data) I was trying with post_save and sender like this but failed : @receiver(post_save) def update_user(sender, instance=None, created=False): list_of_models = ('CustomUser', 'UserDashboard') if sender.__name__ in list_of_models: if created: pass I have trouble understanding with post_save, guys can u help me?? thanks a lot -

Redirect all api calls on Http to Https in Nginx
I am running a Django app and deployed it on server using Gunicorn and Nginx. It was running on Http for a year. Now I changed it to Https using "letsencrypt". Here is my nginx configuration. server { server_name my_project.com; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/ubuntu/my_project/my_project/; } location / { proxy_pass_header Server; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Scheme $scheme; proxy_connect_timeout 10; proxy_read_timeout 10; proxy_pass http://localhost:8000; } listen 443 ssl; # managed by Certbot ssl_certificate /etc/letsencrypt/live/my_project.com/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/my_project.com/privkey.pem; # managed by Certbot include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot } server { if ($host = my_project.com) { return 301 https://$host$request_uri; } # managed by Certbot listen 80; server_name my_project.com; return 404; # managed by Certbot } This configuration works fine when I open project page in browser i.e. it redirects me to https page. But none of my Api calls work. I got error that method not found. Kindly guide me how can I resolve this issue? -

How to pass non-form data in django form object?
I have a data dictionary and want to validate and clean that data to store in database table as defined in models.py My approach was creating a form class then create an instance of that form class and pass data dictionary instead of request.POST in the view.py. But this is not working. No error, but cleaned_data returning an empty dictionary. data = { 'story_title': i.title.text, 'story_source': Sources.objects.get(source_url= source_url), 'pub_date': i.pubDate.text[5:16], 'body_text': des, 'url': i.link.text } story_form = StoryForm(data) if story_form.is_valid(): story_data = story_form.cleaned_data new_story = Stories( story_title = story_data['story_title'], story_source = story_data['story_source'], pub_date = story_data['pub_date'], body_text = story_data['body_text'], url = story_data['url'] ) new_story.save() I am not confirm that my approach is right or wrong. While searching for solution I came across HttpRequest.body in Django docs which only says that HttpRequest.body is used to populate form instance with the non-form data / raw data (nothing about how to use). -

Django : Updating model by overriding save method

Parse ISO 8601 date format in django tables2
I am using django tables2 which: Note that format uses Django’s date template tag syntax. According to django date ISO 8601 is selected by the format string 'c': c ISO 8601 format: 2008-01-02T10:30:00.000123+02:00 So that's what I do: import django_tables2 as tables ... created = tables.DateTimeColumn(format='c') But that does not work (the created column in the table is shown empty, a sign of parsing problems) This is the data coming from the API: "created": "2018-09-05T14:00:35.672433Z", which is actually coming from DRF, which by default uses: format - A string representing the output format. If not specified, this defaults to the same value as the DATETIME_FORMAT settings key, which will be 'iso-8601' unless set To summarize, my question is: How to parse iso8601 with django tables2? -
What is ":" in "reverse()"?
So, I was watching TheNewBoston's video on YT and noticed he wrote this - def get_absolute_url(self): return reverse("music:detail", kwargs = {"pk" : self.pk}); And that took him to the detail view of his model, but how did ":" work? Did this automatically created the detail view for him or did he somehow referenced it? -

Django - automatically create a model instance when another model instance is created
I have an overrided User model and a Cart model. I expect that a Cart model instance is created automatically once a User model instance is created. I am trying to pass the registered user into the get_queryset method, but no idea how to do it. Are there any other better ways to do this? It's because I may need to do the same thing for other models unlike the User model which has a form which can pass values to the get_queryset method. account/models.py: class Cart(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True) def __str__(self): return self.user.email + '_cart' account/views.py: class RegisterView(generic.CreateView): template_name = 'account/register.html' form_class = RegisterForm success_url = reverse_lazy('book:home') def get_queryset(self): sign_up = self.request.POST.get('register') if sign_up: c = Cart.objects.create(user=???) c.save() account/templates/account/register.html: <form name="register" method="post">{% csrf_token %} {{ form.as_p }} <input type="submit" value="Sign Up"> </form> -

Inner join like search using many to many relationship
I am unable to figure out how to retriever objects using an advanced Q search any perhaps am approaching it in the wrong way entirely. I think it'll be easier for me to fully define the models before I attempt to describe the problem.

I am getting the following error using Django 2.1: Page not found (404) Request Method: POST Request URL: http://localhost:8000/user-accounts/%5Eregister/ Using the URLconf defined in my_project.urls, Django tried these URL patterns, in this order: admin/ user-accounts/ ^register/$ [name='register'] user-accounts/ ^login/$ [name='login'] user-accounts/ ^logout/$ [name='logout'] bank-accounts/ The current path, user-accounts/^register/, didn't match any of these. When I click a link in the header set in my base.html, I get the strange url http://localhost:8000/user-accounts/%5Eregister/ in browser. The links in base.html are: <li class="dropdown-header"><a href="{% url 'user-accounts:register' %}">Register</a></li> <li class="dropdown-header"><a href="{% url 'user-accounts:login' %}">Login</a></li> The user accounts app urls.py: from django.urls import path from django.contrib import admin from . import views app_name = 'user-accounts' urlpatterns = [ path(r'^register/$', views.register, name='register'), path(r'^login/$', views.user_login, name='login'), path(r'^logout/$', views.user_logout, name='logout'), ] The project urls.py: from django.contrib import admin from django.urls import path, include from user_accounts.views import register urlpatterns = [ path('admin/', admin.site.urls), path('', register), path(r'user-accounts/', include('user_accounts.urls')), path(r'bank-accounts/', include('bank_accounts.urls')), ] Thank you -
Unpacking a JSONField into multiple django form fields
I am using a JSONField from django.contrib.postgres.fields in my Django model. I want to set up my update form so that it looks at the object being passed into it, iterates through the JSON from the JSONfield, and dynamically creates the right amount of CharFields. models.py: class myclass(models.Model): purpose_section = JSONField() forms.py: class myclassForm(forms.ModelForm): class Meta: model = myclass fields = '__all__' def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) for i in self.fields['purpose_section'].initial: self.fields['purpose_section_%s' % i] = forms.CharField(label="purpose_section_" + i,value=i.content) When I try to access the page, I receive an error: 'NoneType' object is not iterable Any ideas on what I'm missing? -
