Update Django model field by CSV file upload via change_form.html override
Django is still not my superpower, so I hope that some of you could help me to find a way to achieve my goal, which is: I need to find a way to get "Upload file" feature at Django admin change_form.html template. By uploading that file my app would be able to update body of the specific instance of Content model (with fields id, title and body). I already implemented solution for similar problem, which is how to add new objects by clicking custom "Upload csv" button in admin panel. I achieved it by following this solution: I added this in app's admin.py file: from .models import Content class CsvUploadForm(forms.Form): csv_file = forms.FileField() class CsvUploadAdmin(admin.ModelAdmin): change_list_template = "admin/change_list.html" def get_urls(self): urls = super().get_urls() additional_urls = [ path("upload-csv/", self.upload_csv), ] return additional_urls + urls def changelist_view(self, request, extra_context=None): extra = extra_context or {} extra["csv_upload_form"] = CsvUploadForm() return super(CsvUploadAdmin, self).changelist_view(request, extra_context=extra) def upload_csv(self, request): if request.method == "POST": form = CsvUploadForm(request.POST, request.FILES) if form.is_valid(): if request.FILES['csv_file'].name.endswith('csv'): try: decoded_file = request.FILES['csv_file'].read().decode( 'utf-8') except: self.message_user( request, "Can not decode the file, please check its content if valid CSV format", level=messages.ERROR ) return redirect("..") content_body = decoded_file content_title = request.FILES['csv_file'].name try: csv.reader(content_body.splitlines()) except: self.message_user( request, … -
Does default isolation level setting in Django depend on database?
I read Isolation level in Django documentation and it says as shown below: Like PostgreSQL itself, Django defaults to the READ COMMITTED isolation level. So, if I use Django with MySQL whose default isolation level is REPEATABLE READ: Is the default isolation level setting in Django also REPEATABLE READ? Or Is the default isolation level setting in Django READ COMMITTED? -
Error when importing models into test.py file, django
I'm trying to create a test.py file for some of my database methods in a current django project. I need to import my models.py file, but the import statement I'm using below (which follows the official Django example) is causing an error. Both test.py and models.py are already in appFolder, so is that the issue? from appFolder.models import Class1,Class2,Class3 Using only 'import models' didn't work when I ran it earlier. How can I resolve this? (I have also been running the file with the command './manage.py test' if that's relevant) -
How to create custom validation within custom model field type?
I am trying to make a school management system where super users who can add new students (and teachers later on) on the database have to also enter the student's courses. However, I want to use validation for different purposes: Students need to take at least and a maximum of 1 option from the English and Math field (which does not need any further validation if left as it is) Students need to take at least 1 science and a maximum of 2 --> Needs validation to ensure courses are not taken twice. Students can pick any 3 courses from Science, Art, and Society, but cannot take the same courses twice. I apologize if this question is silly or for any errors in the code as I started learning django and html 3 days ago to complete a school project. I read the django documentation in hopes for an answer but I couldn't find what I was looking for. class Student(models.Model): student_number = models.PositiveIntegerField() first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) email = models.EmailField(max_length=100) class English(models.TextChoices): LANGLIT = 'LL', _('Language and literature') LIT = 'L', _('Literature') english = models.CharField(max_length=2, choices=English.choices, default=English.LANGLIT) class Math(models.TextChoices): AA = 'AA', _('Analysis & Approaches') AI = … -

How to reduce inventory when creating a purchase instance in Django?
I'm working on a Django project that is a simple restaurant management system. One of the key functionalities is to record inventory and purchases. I'm looking to add functionality where once I create a Purchase instance, my program automatically reduces the inventory by the amount used in that purchase. I've been scratching my head a bit and poking around the internet but I'm honestly not sure exactly where to start. This is my first Django project so would greatly appreciate a bit of direction. See below for my models.py and views.py. Models.py class Inventory(models.Model): ingredient_name = models.CharField(max_length=30) price = models.DecimalField(max_digits=5, decimal_places=2) units_avail = models.IntegerField() def __str__(self): return self.ingredient_name + " avail: " + str(self.units_avail) def get_absolute_url(self): return "/inventory" class MenuItem(models.Model): menu_item_name = models.CharField(max_length=100) price = models.DecimalField(max_digits=5, decimal_places=2) def __str__(self): return self.menu_item_name + " with Price: " + str(self.price) def available(self): return all(recipe_req.enough() for recipe_req in self.reciperequirement_set.all()) def get_absolute_url(self): return "/menu" def cost(self): item_cost = 0 for recipe_req in self.reciperequirement_set.all(): item_cost += recipe_req.ingredient.price return item_cost def profit(self): item_cost = self.cost() item_profit = self.price - item_cost return item_profit class RecipeRequirement(models.Model): ingredient = models.ForeignKey(Inventory, on_delete=models.CASCADE) menu_item = models.ForeignKey(MenuItem, on_delete=models.CASCADE) quantity = models.IntegerField() def __str__(self): return self.ingredient.ingredient_name + " in " + self.menu_item.menu_item_name def … -

How would you achieve this Dynamic updating
I have this simple form "Manufacturers" have a DB, "Models" have a DB with a ForeignKey to Manufacturers. There are indoor and outdoor systems which are simply provided in the Models DB FIRST Dynamic updating - This is what I want to happen with the above. When "Indoor Manufacturer" is selected, "Indoor Model" shows relevant records on "Indoor Model". Ditto for "Outdoor Manufacturer" & "Outdoor Model" SECOND Dynamic updating - But to make the form a tad easier, when the Checkbox "Indoor/ Outdoor Unit Same Manufacturer" is clicked, it locks "Outdoor Manufacturer" to what is selected in "Indoor Manufacturer" - it still needs to update "Outdoor Model" selection though I'm not entirely new to Django, but still very much a Beginner. I can manage the First Part using HTMX but then I run into a brick wall with trying to combine the First Part & the Second Part. I suspect I'm reaching the limits of my ability here and may be using HTMX incorrectly, so look for advice on how others would approach this? -
How to prevent my queries from getting out of order when I show them in the template with a nested loop
I am making a query to the database, ordering it by date and then sending it to the template, but it is displayed out of order in the template. I think the problem is the nested loop. When i take out the nested loop it worked but i really need the loop to be there. How can I make it work? This is the query from the view: recibos=grupo.recibos.all().order_by('-fecha_pago') This is the template code: {% if recibos %} <table class="table table-responsive-sm table-sm table-hover datatable"> <thead> <tr> <th>Responsable</th> <th class="text-center">Fecha</th> <th class="text-center">Monto</th> <th class="text-center">Forma de Pago</th> <th class="text-center"></th> </tr> </thead> <tbody> {% for recibo in recibos %} <tr> <td> <div>{{recibo.responsable.nombre}} {{recibo.responsable.apellido}}</div> <div class="small"><span>&nbsp;&nbsp;<i class="fa-solid fa-graduation-cap"></i></span> {% for alumno in recibo.alumnos.all %} {% if not forloop.last %} {{alumno.nombre}}, {% else %} {{alumno.nombre}} {% endif %} {% endfor %} </div> </td> <td class="text-center"> <div>{{recibo.fecha_pago}}</div> </td> <td class="text-center"> <div>${{recibo.importe|floatformat:"2g"}}</div> </td> <td class="text-center"> <div>{{recibo.forma_pago}}</div> </td> <td class="text-center"> <div>botones</div> </td> </tr> {% endfor %} </tbody> </table> {% else %} <br> {% if filtro == True %} <div class="alert alert-warning text-center"> <strong>No hay resultados para este filtro</strong> </div> {% else %} <div class="alert alert-warning text-center"> <strong>No hay recibos para esta familia</strong> </div> {% endif %} {% endif … -
