Creating query in nested django model and group the results in django
I am trying to create query in my postgresql database with django ORM and then group the results by specific ip_addr. Here is my models: class Report(models.Model): network = models.CharField(max_length=50) timestamp = models.CharField(max_length=30) def __str__(self): return f"{self.network}_{str(self.timestamp)}" class Device(models.Model): report = models.ForeignKey(Report, on_delete=models.CASCADE) ip_addr = models.GenericIPAddressField() mac_addr = models.CharField(max_length=20) date = models.DateTimeField(default=timezone.now) def __str__(self): return self.ip_addr class Port(models.Model): host = models.ForeignKey(Device, on_delete=models.CASCADE) port = models.IntegerField() status = models.CharField(max_length=15) application = models.CharField(max_length=100) def __str__(self): return str(self.port) When I perform query Port.objects.filter(host__report_id=pk) I get all the port in specific Report. My problem is that I do not know how to group all ports whit the ip_addr they belong to. I will appreciate any useful advice. -

How to combine a form and multiple formsets for the same model in a view?
I have three models "parent - child - grandchild". I would like for one view to handle one form for parent, one formset for child and multiple formsets for grandchild. Specifically; parent_1_form child_1_formset (children of parent_1) child_1_form (form 1 of formset) grandchild_1_formset (children of child 1) child_2_form (children of parent 1) grandchild_2_formset (children of child 2) So I want to create a parent form, then a child formset and for each child form I want a new grandchild formset. Especially this last part seems challenging, to have multiple formsets for a single model in one view. I can manage to create a parent form, child formset and grandchild formset in one view. However I am unsure how I would be able to combine multiple formsets for the same model into one view. Could anyone give some advice on how to structure this? -
How to convert select_related queries in Django into a single dataframe
I am working in Django and I would like to simply merge three tables into one dataset. My models look like so and I have tried variants of the following command: class Quadrat(models.Model): quadrat_number = models.IntegerField() class Capture(models.Model): quadrat= models.ForeignKey(Quadrat, on_delete=models.DO_NOTHING) capture_total = models.IntegerField() class Species(models.Model): capture = models.ForeignKey(Capture, on_delete=models.DO_NOTHING) species = models.CharField(max_length=50) data = pd.DataFrame(list(Species.objects.select_related('Capture_set', 'Quadrat_set').all() I get an attribute error: Cannot find 'Capture_set' on Species object, 'Capture_set' is an invalid parameter to select_related() I am probably using select_related wrong. Any ideas ? -
Django - Is it possible to translate only some of the models (admin forms)?
Say that you have a django admin site with the common users/groups fields, and some other fields that you like to leave as plain English, yet some of the forms you need to translate to another pre-defined language: Think Hebrew/Arabic where the interface can easily be changed to RTL by using a CSS, but then the English in the page does not fit, because the page is ... right to left, and it is desirable that not only the fields are translated, but also the titles. The documentations, and many other solutions here shows that there is good support to translate the whole admin site, by setting the language to the whole site, but I could not find how to set the language specifically to some forms, which seems not a very unreasonable request, I am sure others have raised before... -
Django annotate, combine multiple related values onto same instance
I have a django app with the following models: class Person(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) class Job(models.Model): title = models.CharField(max_length=100) class PersonJob(models.Model): person = models.ForeignKey(Person, related_name='person_jobs') job = models.ForeignKey(Job, related_name='person_jobs') is_active = models.BooleanField() Multiple Person instances can hold the same job at once. I have a Job queryset and am trying to annotate or through some other method attach the names of each person with that job onto each item in the queryset. I want to be able to loop through the queryset and get those names without doing an additional query for each item. The closest I have gotten is the following: qs = Job.objects.all().annotate(first_names='person_jobs__person__first_name') .annotate(last_names='person_jobs__person__last_name') This will store the name on the Job instance as I would like; however, if a job has multiple people in it, the queryset will have multiple copies of the same Job in it, each with the name of one person. Instead, I need there to only ever be one instance of a given Job in the queryset, which holds the names of all people in it. I don't care how the values are combined and stored; a list, delimited char field, or really any other standard data type would be … -
Is it possible in django ModelForm to leave Filefield empty?
I want to make an app where you can upload few files, where only one is required - you are obligated to choose one file, but the others are optional. If I don't choose all the files I get: MultiValueDictKeyError at /fpFilterRun/ At the beginning I was using Form, now I switched to ModelForm, tried to check if fileFields are empty or not, digged through I believe whole Stack and nothing helped. models.py class FPFilter(models.Model): QueryName = models.CharField(max_length=25) DCAfile = models.FileField() MSAfile = models.FileField(blank=True, null=True) SSfile = models.FileField(blank=True, null=True) RSAfile = models.FileField(blank=True, null=True forms.py class FPFilterForm(ModelForm): class Meta: model = FPFilter fields = ['QueryName', 'DCAfile', 'MSAfile', 'SSfile', 'RSAfile'] labels = { 'QueryName': 'Query name:', 'DCAfile': 'DCA file:', 'MSAfile': 'MSA file:', 'SSfile': 'Secondary Structure file:', 'RSAfile': 'Relative Solvent Accessibility file:', } views.py def fpFilterRun(request): if request.method == 'POST': fpfilter_form = FPFilterForm(request.POST, request.FILES) if fpfilter_form.is_valid(): query_name = request.POST['QueryName'] DCADict = save_file(request.FILES["DCAfile"], saveDir) if request.FILES['MSAfile'] is not 'u''': MSADict = save_file(request.FILES['MSAfile'], saveDir) MSAPath = MSADict['filePath'] else: MSAPath = 'empty' if bool(request.FILES['SSfile']) is False: SSDict = save_file(request.FILES['SSfile'], saveDir) SSPath = SSDict['filePath'] else: SSPath = 'empty' if request.FILES['RSAfile'] is not None: RSADict = save_file(request.FILES['RSAfile'], saveDir) RSAPath = RSADict['filePath'] else: RSAPath = 'empty' else: fpfilter_form = … -
How to use imports from requirements.txt in python

Django select_related chained foreign keys doesn't return non-direct related objects
I have been through multiple other posts so this one might seem a duplicate but I couldn't find an answer. I'm new on the platform so I apologies if this is not the proper way to proceed. I use Django 2.2 Based on the official doc, it says that select_related() returns a QuerySet that will “follow” foreign-key relationships, selecting additional related-object data when it executes its query: https://docs.djangoproject.com/en/2.2/ref/models/querysets/#select-related Here is the official example: You can follow foreign keys in a similar way to querying them. If you have the following models: from django.db import models class City(models.Model): # ... pass class Person(models.Model): # ... hometown = models.ForeignKey( City, on_delete=models.SET_NULL, blank=True, null=True, ) class Book(models.Model): # ... author = models.ForeignKey(Person, on_delete=models.CASCADE) then a call to Book.objects.select_related('author__hometown').get(id=4) will cache the related Person and the related City: # Hits the database with joins to the author and hometown tables. b = Book.objects.select_related('author__hometown').get(id=4) p = b.author # Doesn't hit the database. c = p.hometown # Doesn't hit the database. # Without select_related()... b = Book.objects.get(id=4) # Hits the database. p = b.author # Hits the database. c = p.hometown # Hits the database.

Django tutorial. Generic views. context_object_name = 'latest_question_list'
I'm a bit confused with Django generic views. As shown in here we are converting custom views into generic views. And while I understand what happens in DetailView and ResultsView, I don;t entirely grasp how this: def index(request): latest_question_list = Question.objects.order_by('-pub_date')[:5] template = loader.get_template('polls/index.html') context = { 'latest_question_list': latest_question_list, } return render(request, 'polls/index.html', context) converts into this: class IndexView(generic.ListView): template_name = 'polls/index.html' context_object_name = 'latest_question_list' def get_queryset(self): """Return the last five published questions.""" return Question.objects.order_by('-pub_date')[:5] In the first example, latest_question_list = Question.objects.order_by('-pub_date')[:5] But in the second example, what latest_question_list variable is equal to in here? We haven't even defined it.. Can anyone please shed some light into this? -

Django Admin - prevent save under certain conditions and display message to user
I am putting together a Django app - created and registered the models and model forms. When adding or editing a particular model record, I need to call an external service for some information. If the information is retrieved successfully I want to update a column on that model which the user is unaware of and save the model. If the call fails I need to prevent the save from occurring and a custom message returned to the user. I have tried raising Exceptions, returning messages as String etc but nothing seems to work. Although I can stop the save from occurring I end up with a stack-trace if I don't return the model. I have seen various solutions using the clean() method or signals but none seem to suit the need. The order of things I need to happen: Validate the Form data being entered (happens automatically) Do the API call to the external service to retrieve the info Assign the info to the model prop and save the model If API call fails, cancel save() and display message to user I just cannot seem to find a simple solution out there - any help appreciated! -
Django many-to-many inline model admin selects waaay too many rows from rel
I am trying to make a n-to-n rel work the way that it shows the corresponding relationship in the admin page for each of the two models in this rel. Out of the box only the model that has the relationship defined on it gets the form on its admin page. So i have followed the official documentation: https://docs.djangoproject.com/en/2.2/ref/contrib/admin/#inlinemodeladmin-objects As you should see(below in my code) i have basically added exactly what it says. Now my problem is that i have about 350k rows in this mapping table, but if i select in my database one bar only has 80 foos, and the reverse selection maybe 140. Now it seems like it selects 147k rows(!), so it seems like it somehow selects about half of my entire join table even though i am just clicking on a specific foo. So somehow it seems like it isn't doing just a simple join between the two models with ids, when i look in my sql log the SQL it generates is just selecting things from one table at a time, which is weird because the join can be done in 1 line. So i have a Django app that has the following … -

Django - In a survey app that uses forms is it necessary to use Formsets?
I'm currently working with a survey app. The answers are stored in a table created by a very simple model: class Answer(models.Model): user = models.ForeignKey(User, on_delete=models.PROTECT, null=False) item = models.ForeignKey(Item, related_name = "question", on_delete=models.PROTECT, null = True) answer = models.TextField() So for example, if the survey has 10 questions, 10 rows would be created in the database for each user. Given the above, the form to be created must have multiple questions and the corresponding inputs to answer. My questions are: 1. For these cases it is obligatory to use formsets? 2. If it is not mandatory, is it recommended? or is there a better way to deal with this problem?
