Error Message in request.POST Form not showing up
I've written a normal contact POST-form: def emailView(request): if request.method == "POST": form = ContactForm(request.POST) if form.is_valid(): context = {'form': form} return redirect('success_contact') else: form = ContactForm() Then in my form this template tags: <form id="contact_form_post" method="post"> {% csrf_token %} {{ form.name }} {{ form.name.errors }} {{ form.message }} {{ form.message.errors }} <div class="form-actions"> <button type="submit">Submit</button> </div> </form> With this setup, no error message is showing up if the required fields are not filled out. When I'm changing the last line in emailView into form = ContactForm(request.POST) every error message shows up before submitting -> "This Field is required". -

New way of implementing enumeration type (choices) in Django 3.0
I've seen a new way to implement enumeration type in the upcoming Django 3.0. The given example is: class Student(models.Model): class YearInSchool(models.TextChoices): FRESHMAN = 'FR', _('Freshman') SOPHOMORE = 'SO', _('Sophomore') JUNIOR = 'JR', _('Junior') year_in_school = models.CharField( max_length=2, choices=YearInSchool.choices, default=YearInSchool.FRESHMAN, ) I used to put my enumerate list in the __init__.py to have a more readable code in models.py because the list (like status or other things can be long). So I was wondering if this new way of implementing could be safely rewritten as following: from my_app import YearInSchool class Student(models.Model): @cached_property def years_in_school_choices(): return YearInSchool Not sure here neither if cached_property is relevant. -

Django search on date field with MySQL DB
I have a date field in one of my models. I want to develop a search service, which in user sends a query param as search key, for example '?search=2018' and the response would be all rows in data base that their date's year is 2018. Or if the user sent '?search=11' the response would be all rows that either their date's month is 11, or their date's day is 11. I am using django 2 and MariaDB version 10.3.18 -

Get available time slots for appointment booking using Django REST framework
I am trying to develop an API for scheduling appointments for several salons. Right now I have models and serializers for the Salon and the Appointment. All appointments can have different durations. The Appointment model looks like this: class Appointment(models.Model): date = models.DateField() start_time = models.TimeField() end_time = models.TimeField() salon = models.ForeignKey(Salon, on_delete=models.CASCADE) How can I return all salons and their available time slots (no appointment at that time) for a given date. So say if a salon is open from 10:00-16:00 and has only one appointment from 11:00-11:30 we would get something like: { "id": 3, "name": "My Salon", "city": "London", "time_slots": [ { "date": "2019-12-01", "start_time": "10:00:00", "end_time": "11:00:00", }, { "date": "2019-12-01", "start_time": "11:30:00", "end_time": "16:00:00", } ] } Right now the only way I can think of is by adding a new TimeSlot model with Salon as Foreign key and saving all time slots in the database and changing them once an appointment is made? However, this does not seem very efficient. Is there a better way of calculating and returning the time slots? -

Is there a way of printing user id in uwsgi django log?
I think it would be very convenient to have a user-id in the uwsgi request/response log. I know there's logformat option available in uwsgi. And I don't think user-id could be handled by logformat since it's not something uwsgi natively knows, it's app (my case django)'s data that runs inside uwsgi (if that expression makes sense) On the other hand, there's django logger's format and I guess I could make a middleware that prints a request/response data with user-id although this would be duplication of what uwsgi itself is logging. (although uwsgi's log don't have user-id) -

How do I get an image to render in weasyprint using a Django Template in production?
I am trying to get an image to render using Weasyprint with Django in production. I can get it to work with debug=True on my local machine, but cannot get it to work on my apache server with debug=True or False or with debug=False on my local machine. It's like it can't render out the url for the image source properly. The PDF is returned properly, and if I stick the {% static 'image.png' %} in the template as text it comes back with: /static/img/image.png What exactly am I missing?

django for python set up issues
I'm not familiar with using command prompt and having trouble at the start of the django for python set up process which i'm reading here: https://docs.djangoproject.com/en/2.2/intro/tutorial01/ My problem appears to be the 'python' command doesn't work (please see my command prompt screen shot). I tried adding it into 'System variables' in the 'Environment Variables' as shown in the other screen shot. Is there something i have done incorrectly here? Also although i can get the create the initial project the only place i can create it is in the 'c:\Python\Lib\site-packages\django\bin' folder because i have to be looking at this folder in order to run the django-admin.py file. I think the second issue is related to the first issue though i.e. if the 'python' command worked i could just run 'python django-admin.py startproject mysite' while my directory path is set to where ever i want the project to be created. I expect i could simply move the mysite folder to where i want it but i feel i need to understand why this all isn't working as expected before moving on. -
django orm: select_related, fooling reverse foreign key with a fake foreign key addition to the model, what can go wrong?
I am trying to learn how to use Django's ORM for more advanced queries, instead of using raw sql. select_related makes joins to reduce database hits, in principle it could make the joins that I would do manually. But there is a problem: It doesn't use reverse foreign key relationships to make the sql. For the schema I have this is a nuisance. I have found what looks like a surprisingly easy work around, and I'm worried that it will be incorrect in ways I don't understand. I'm using a legacy DB, and it is read-only, and therefore unmanaged by the ORM, and there are no consequences for cascade settings. I have made models for its tables via manage.py analysedb which did a very good job; I have a 6000 line model file, and only needed to spend ten minutes fixing things. One tweak I did was a hack to fool select_related by creating a foreign key relationship which is actually a reverse FK relationship. This means I have two entries in my model pointing to the same database column, which is the primary key (correct) and also now a foreign key. I exploit the "new" column in select_related. The … -

Here is my nginx configuration: server { listen 80 default_server; listen [::]:80 default_server; server_name _; return 301 https://example.com$request_uri; } server { listen [::]:443 ssl ipv6only=on; listen 443 ssl; server_name example.com example.com; root /var/www/html/; index index.html; # Let's Encrypt parameters ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; location / { try_files $uri $uri/ = index.html; } location /api { proxy_pass http://unix:/run/gunicorn.sock; proxy_redirect off; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; } } In the first block..I'm setting fallbacks to index.html because it is an angular app. The angular app runs fine. But I'm not able to access the routes of the reverse proxy server, whenever I hit a route with /api/something it takes me back to the angular app i.e index.html -

How to set small icon size for`tinymce` in mobile screens?
I added tinymce4-lite in my Django application. The size of icons looks the same in bigger screens and small screens. Big Screens: Small Screens: the size of icons are similar in either big and small screens. I want it to be smaller and more elegant in mobile size screens.

How to show BinaryField image preview in Django admin interface?
I've got web project with Django backend for which I decided to store images as BinaryField, it seemed to be more convenient for me in case of making backups and restoring them. At first I've created model: class ThermalSource(ClusterUnit): ... scheme_image = models.BinaryField(verbose_name='Scheme', blank=True, null=True, editable=True) ... Then created serializer to use in viewset (I know it is not related to admin interface, but maybe it will be useful): class Base64BinaryField(serializers.Field): def to_representation(self, value): from base64 import b64encode return b64encode(value) def to_internal_value(self, data): from base64 import b64decode return b64decode(data) class ThermalSourceSerializer(APAMModelSerializer): ... scheme_image_base64 = Base64BinaryField(source='scheme_image') ... Now I could get and set images converted to Base64 correctly via Django REST Framework. Admin class for ThermalSource looks so now: class ThermalSourceForm(forms.ModelForm): scheme_image = forms.FileField(required=False) def save(self, commit=True): if self.cleaned_data.get('scheme_image') is not None \ and hasattr(self.cleaned_data['scheme_image'], 'file'): data = self.cleaned_data['scheme_image'].file.read() self.instance.scheme_image = data return self.instance def save_m2m(self): # FIXME: this function is required by ModelAdmin, otherwise save process will fail pass class ThermalSourceAdmin(admin.ModelAdmin): form = ThermalSourceForm readonly_fields = ('id', ) list_display = ('id', ... 'scheme_image') But when I open Django admin interface, I could only download files to scheme image field, no preview is configured. Could anybody suggest me how could I …
