Formset with request.post not initializing correctly
I am having an issue using formsets and request.POST. Whenever I initialize the formset without request.POST it works as intended, but will not send the data through as the form is never valid. If I include request.POST (as I have done on all my other forms in the view) the formset doesn't seem to initialize correctly. No data gets through, I can't see any form fields, and I get a html warning saying: (Hidden field TOTAL_FORMS) This field is required. (Hidden field INITIAL_FORMS) This field is required. Here is a very simplified version of what I am doing in my project. This is bare minimum and the project itself is much more involved. But this should be the heart of the problem I am having. The intent of this very basic form is that my formset would have 3 forms, each one initialized with a letter, 'a', then 'b', then 'c'. views.py def MyView(request): my_formset = formset_factory(my_form) my_list = ['a', 'b', 'c'] if request.method == 'POST': my_formset = formset(request.POST, initial=[{'field1':x} for x in my_list]) #If I remove 'request.POST' then the form initializes correctly, but will never pass .is_valid() if my_formset.is_valid(): print('valid') else: print('invalid') else: my_formset = formset(initial=[{'field1':x} for x in … -

Does python web frameworks like Flask/Django have a build process?
I have recently started learning CI/CD concepts. In the tutorials, they used a react website to show the build stage. I was wondering do we have a build phase for applications developed using frameworks like Django/flask? For these applications, we generally run a single command to start the application directly from source code like: python manage.py runserver python app.py Also, in general, is to possible (and okay?) for a web application not to have a build phase? Any knowledge here would be helpful. Thanks in advance! -
Django test fails to run migrations
I'm trying to run a test script, following this django doc (which is the version being used here). It quickly fails with a long stack. I've selected what's the possible culprit.

In Django, how do I add a join table relation to an existing model?
I'm using Python 3.9 and Django 3.2. I have these models. The second is a join table for the first class Coop(models.Model): objects = CoopManager() name = models.CharField(max_length=250, null=False) types = models.ManyToManyField(CoopType, blank=False) addresses = models.ManyToManyField(Address, through='CoopAddressTags') class CoopAddressTags(models.Model): # Retain referencing coop & address, but set "is_public" relation to NULL coop = models.ForeignKey(Coop, on_delete=models.SET_NULL, null=True) address = models.ForeignKey(Address, on_delete=models.SET_NULL, null=True) is_public = models.BooleanField(default=True, null=False) I would like to actually reference the join table in my first model, so I added address_tags = models.ManyToManyField('CoopAddressTags') like so class Coop(models.Model): objects = CoopManager() name = models.CharField(max_length=250, null=False) types = models.ManyToManyField(CoopType, blank=False) address_tags = models.ManyToManyField('CoopAddressTags') addresses = models.ManyToManyField(Address, through='CoopAddressTags') but I'm getting this error when I run a script to generate migraitons $ python manage.py makemigrations directory SystemCheckError: System check identified some issues: ERRORS: directory.Coop.address_tags: (fields.E303) Reverse query name for 'directory.Coop.address_tags' clashes with field name 'directory.CoopAddressTags.coop'. HINT: Rename field 'directory.CoopAddressTags.coop', or add/change a related_name argument to the definition for field 'directory.Coop.address_tags'. I'm not clear what this means or how to resolve it. The goal is that when I have a "Coop" object, I can reference its addresses and whether or not those addresses are public. -

Get files from Aw3 and append them in a .zip in Django
I would like to download some files from Aw3 in a .zip, with all these files. I am using django==2.2.1 with boto3 library, last version.

Cannot add extra styles to django-ckeditor
django-ekeditor packages comes with highlight.js library for code snippets and that library comes with some pre-installed styles. As I prefer seti-ui style, I download it from highlightjs.org. Inside the downloaded package is seti-ui.min.css file and I copy it to \venv\Lib\site-packages\ckeditor\static\ckeditor\ckeditor\plugins\codesnippet\lib\highlight\styles where all other styles are and then set this in my settings.py: 'codeSnippet_theme': 'seti-ui' # based on the name of css file And it doesn't work. The editor shows the code snippet but without any style. I've tried several other pre-installed themes like monokai and foundation and they work fine. Then I noticed that seti-ui.min.css is inside a subfolder base16 in the package I downloaded from highlightjs.org, so I tried \venv\Lib\site-packages\ckeditor\static\ckeditor\ckeditor\plugins\codesnippet\lib\highlight\styles\base16 too but didn't work either. So what is the correct method to add it? -
Django/Python - update html after update with radiobutton
I have a Django app with an email box. Users can send the email by hand or let it be done automatically. To change the setting: either manual or automatic, I have creates a view to change the settings. To show the user what the current setting is, I prechecked the radio button. It looks like this: My problem is, that when the button "Update" is clicked, it does change the settings, but not the frontend for the user. So the user does not see that it is changed. So the page should be refreshed or something with the new settings, but I don't know how.. This is the code that I have now: .html <div class="form-group"> <label class="form-label">Send Emails:</label> <p></p> <input type="radio" name="update_type" value="manual" {% if view.manualSetting %}checked {%endif%}> Manual {% if view.manualSetting is 1 %} ( Current setting ) {% else %} {% endif %}</input> <p></p> <input type="radio" name="update_type" value="auto" {% if view.autoSetting %}checked {%endif%}> Automated {% if view.autoSetting is 1 %} ( Current setting ) {% else %} {% endif %}</input> <p></p> <button type="submit" class="btn btn-primary">Update</button> </div> views.py class AutoSendView(generic.TemplateView): template_name = 'core/mailbox/autoSendMail.html' context_object_name = 'autosend' extra_context = {"mailbox_page": "active"} model = AutoSendMail.objects.get(id=1) autoSetting = int(model.auto == … -

I can't make migrations between two models in Django
I have a problem with my migrations, it turns out that when I try to do python manage.py migrate I get a series of errors but the one that surprises me the most is the one from heroku: django.db.utils.IntegrityError: insert or update on table "carros_carro" violates foreign key constraint "carros_carro_cliente_id_3c6fe221_fk_Clientes_clientes_id" DETAIL: Key (cliente_id)=(1) is not present in table "Clientes_clientes" So my problem is between those two models, the bad thing is that I already replaced those models that were in my previous folders and the error continues to appear. clientes/models.py class Clientes(models.Model): tipo = models.CharField(max_length=200) TITLE = ( ('Mrs.', 'Mrs.'), ('Miss', 'Miss'), ('Mr.', 'Mr.'), ) corporacion=models.CharField(max_length=200,blank=True) titulo = models.CharField(max_length=200, choices=TITLE,default='Mr.') nombre = models.CharField(max_length=200, blank=True) apellido = models.CharField(max_length=200,blank=True) telefono = models.IntegerField(blank=True, null=True) tel = models.IntegerField(blank=True, null=True) fax = models.IntegerField(blank=True, null=True) correo = models.EmailField(max_length=200,blank=True, null=True) website=models.URLField(max_length=200,blank=True, null=True) social_media=models.CharField(max_length=200,blank=True, null=True) social_media2=models.CharField(max_length=200,blank=True, null=True) social_media3=models.CharField(max_length=200,blank=True, null=True) contacto_alternativo=models.CharField(max_length=200,blank=True, null=True) contacto_alternativo2 = models.CharField(max_length=200,blank=True, null=True) contacto_alternativo3 = models.CharField(max_length=200,blank=True, null=True) pais = models.CharField(max_length=200,blank=True, null=True) direccion=models.CharField(max_length=200,blank=True, null=True) ciudad=models.CharField(max_length=255,blank=True, null=True) estado=models.CharField(max_length=255,blank=True, null=True) zip=models.CharField(max_length=255,blank=True, null=True) fecha_registro = models.DateTimeField(default=datetime.now,blank=True, null=True) def __str__(self): return f'{self.nombre} {self.apellido}' carros/models.py class Carro(models.Model): placas=models.CharField(max_length=255, blank=True,null=True) tipo=models.CharField(max_length=255, blank=True,null=True) marca=models.CharField(max_length=255, blank=True,null=True) modelo=models.CharField(max_length=255, blank=True,null=True) año=models.IntegerField() vin=models.CharField(max_length=255, blank=True,null=True) color=models.CharField(max_length=255, blank=True,null=True) motor=models.CharField(max_length=255, blank=True,null=True) agente_seguros=models.CharField(max_length=255, blank=True,null=True) compañia_seguros=models.CharField(max_length=255, blank=True,null=True) no_politica=models.CharField(max_length=255,blank=True,null=True) cliente= models.ForeignKey(Clientes, on_delete=models.SET_NULL, null=True) fotosCarro=models.ImageField(blank=True, … -

Django behind NGINX reverse proxy and AWS Application Load Balancer doesn't get HTTPS forwarded from client in HTTP_X_FORWARDED_PROTO
I'm running Django on Gunicorn behind a NGINX reverse proxy, and an AWS Application Load Balancer. The ALB has 2 listeners. The HTTPS listener forwards to a Target Group in port 80, and the HTTP listener redirects to HTTPS. The ALB thus connects with an AWS ECS Cluster, which runs a task with 2 containers: one for the Django app, and another for the NGINX that acts as a reverse proxy for the Django app. Here's the configuration for the NGINX reverse proxy: upstream django { server web:8000; } server { listen 80; listen [::]:80; location / { proxy_pass http://django; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Port $server_port; proxy_ssl_server_name on; proxy_redirect off; } } This configuration ensures that whenever the client tries to hit the website app using an HTTP request, he gets redirected to HTTPS. And everything works fine with one exception. In Django, when I run request.is_secure() I'm getting False instead of True as expected. If I run request.build_absolute_uri(), I get http://mywebsite.com and not https://mywebsite.com as expected. I already tried adding the following lines to settings.py: USE_X_FORWARDED_HOST = True SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') as explained in the documentation, but it doesn't … -

Django multi project user management
I want to learn is there a way to keep django multi project and authenticate/authorize them with one project? For example: I have Project-B and Project-C with different operation fields like hotel automation and gas station. Both of them are my products and I want to manage them by keep licences and users in one place, in other words different project, Project-A. In Project-B and Project-C has it's own apps and apps' models so I don't want to merge them in one project, I want to keep them separate. But I want authorize/authenticate users from one place Project-A. So Project-A will be used only for management. I am planning to use OAuth toolkit for it, but in the first place I have another problem. Project-B and Project-C's apps' models have foreign key fields and many to many fields that defined in Project-A like customer itself.

Please help me I’m stuck in understanding how Django ORM works. Here is my very simple models: class Department(models.Model): title = models.CharField(max_length=50) class Employee(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) department = models.ForeignKey(Department, on_delete=models.PROTECT) I want a template that looks like: Department 1 Employee 1 Employee 2 Department 2 Employee 3 Employee 4 But I can’t figure out what I should do in my view and(or) template
