DRF accepts int value although it serialzes to a charfield
Hello good people good Django, I was exploring DRF and made a simple CRUD API and everything was smooth nothing special here. But when trying to test how DRF will handle the different cases of missing and wrong values in a POST request I got something was actually very weird. First, here is an example of a valid body of POST request data: { "title": "It doesn't matter", "description": "A short one because life is fast", "body": "Test test test test" } All is a string as you can see. So, I replaced a string value with an int value instead ( like 96 not "96" for sure ) and surprisingly the POST request was successful, the serializer converted the int value to string and inserts it, it didn't raise an error or anything, so is there an explanation for this? -
How to create search view for movie database that can find movie based on title, and tittle + year in search

Passing a model object (with many fields) from a viewfunction to another using redirect and without saving it
I am quite new in this field... so be gentle :) The problem can be stated as follow: View 1: a form based on a model of 14 fields is presented. The user fills it and presses the post button. (important: not saving the model instance in the DB) View 2: A confirmation page appears containing a summary of what he entered. He is asked then to - cancel (don't bother to erase anything in the database) - edit (is not yet saved but the information can be changed) - confirm it (now it's time to save it in the database). And should be accessible only one time, if not completed... it disappears (avoid to create an enormous number of instance in the DB) At the moment everything is static as it save in the DB from the start and stay there, so if someone jsut leave, it will remain in the DB for nothing I looked for some solutions but always cracked below errors. The first one is to directly pass the model instance (Mycard) which landed to > 'str' object has no attribute '_meta' So I looked to pass the information through the URL but it looks like … -
Search engine url, removal get data from empty forms fields. Django, queryset
I create a simple search engine in django. I would like to get a nice URL from here, even if a field will not be selected. For example, I have a simple form in my forms.py class SearchForm(forms.Form): province = forms.ChoiceField(choices=PROVINCE, required=False) brand = forms.ChoiceField(choices=BRAND, required=False) price = forms.IntegerField(required=False) In my views.py, I use it in such a way: def search(request) #data - returns data GET or False province = request.GET.get('province', False) brand = request.GET.get('brand', False) price = request.GET.get('price', False) #search engine form = SearchForm(request.GET) query = Car.objects.all() if province: query = query.filter(province=province) if brand: query = query.filter(brand=brand) if price: query = query.filter(price__gtl=price) return render(request, 'searh.html', {'query' :query}) After filling out the form in the template, URL it looks something like this: http://127.0.0.1:8000/search/?brand=Ford&model=&price= Can I show only the fields that have been selected (As below), if so how to do it? http://127.0.0.1:8000/search/?brand=Ford *does not show '&model=&price='because the user has not entered anything I have one more question, I do not know if I can ask them in this topic.

django inline formset with same parent and child model
I have a Person model which has a parent field which is foreign key to itself, so any instance of this model can have a parent which is another instance of the same model. What I am trying to achieve is to add/update children of a Person using the inlineformsets provided by django. However issue I am having is that inlineformset requires different parent and child models. Models.py from django.db import models # Create your models here. class FamilyMember(models.Model): name = models.CharField(max_length=20) age = models.PositiveIntegerField(null=True, blank=True) job = models.CharField(max_length=20, null=True, blank=True) parent = models.ForeignKey('self', blank=True, null=True, related_name='children', on_delete=models.CASCADE) Views.py def add_child(request): member = FamilyMember.objects.get(name="Tom") child_formset_factory = inlineformset_factory(FamilyMember, FamilyMember, fields=('parent',)) formset = child_formset_factory(instance=member) return render(request, "family/add_child.html", {"formset": formset}) When i render this formset I do not see any children listed for any existing person, even when there are valid records in the db. Instead what I would like to see is this, lets say if a person X has 3 children A, B, C, then I would like to have 3 dropdowns, first dropdown should have A as selected value, second should have B as selected and so on. I am not sure if I am doing it the right way … -

How do i turn off django's plural notation in the admin page
I have some tables that are presented as inlines of another class. I have altered the default title of these inline representations by adding an inner class to the respective tables. class Meta: verbose_name = 'Binnengekomen punten' I have only the verbose_name defined but it still adds an s to all the names. So 'Binnengekomen punten' is displayed as 'Binnengekomen puntens' What i could do is define the plural of verbose_name verbose_name_plural the same as verbose_name. But is there a way to simply turn off the plural notation? I'd love to know thank you. -

Django migrations: what `elidable` argument is for?
I have a RunPython operation in my migrations. This operation accpets an optional elidable argument, which is described in the Django docs: The optional elidable argument determines whether or not the operation will be removed (elided) when squashing migrations. This description is a little bit confusing for me. My question is: what happens, when migrations with elidable=True flag are squashed? I guess that migrations with elidable=True would be simply deleted. And some manual steps would have to be taken in order to add the logic of elided migrations into the squashed one. -

Is there a more elegant way to write this django view?
I've been messing around with django and I have this django view: def handle_results(request): if request.method == "POST" and request.is_ajax(): # Do something with the post request elif request.method == "GET" and request.is_ajax(): # Do something with the get request else: # First time in this view, render first element to display return render( request, "result_page.html", context={"display": arr[0]} ) The main idea is, this is supposed to be a Same Page Application, and the first time I'm in this view, I need to render the contents of the array to display to the user, after that, the user can interact with said array via the html (think of it as upvoting or downvoting stuff that's shown). Depending on the user's choice, I get a GET or POST request and need to deal with said request. However, the way I'm implementing this seems not that elegant and I was wondering if there'd be another better way to accomplish what I'm doing. Thank you so much! -
