How to enrich the Django request object with extended functions?
In my Django project, I have a situation where different views communicate via a request session data as follows: def view_one(request): ... request.session['my_session_key'] = data ... def view_two(request): ... data = request.session['my_session_key'] ... However, this has the following problems: The key string my_session_key is not a constant so it will be hard to scale it up to other parts of the code if I start writing to and/or reading from it in other parts of my code. As this system grows, it will become harder to identify which are the available keys being used and written in the session. In Kotlin (which I'm more familiar with), one way to solve this would be using an extension function, like so: var Request.my_session_key: Int get() = this.session['my_session_key'] set(value) { this.session['my_session_key'] = value } This way, I could now write my views as follows: def view_one(request): ... request.my_session_key = data ... def view_two(request): ... data = request.my_session_key ... Is there any way to accomplish something similar in Python or with Django? Or, alternatively, taking a step back, what would be the best way to organize the data stored in a Django session across multiple views? -
Updating partial data in DB while fetching data should count as GET or PUT request in REST API
My class is to fetch current song info from Spotify api. class GetCurrentSong(APIView): def get(self, request): dict_song_info = get_song_from_spotify(user_session=self.request.session.session_key) if 'Error' in dict_song_info: return Response({dict_song_info['Error_Type']: dict_song_info['Error']}, status=dict_song_info['Status']) # Update song name in database try: self.update_song_info_in_db(dict_song_info['name']) except Exception as ex: return Response({'Storage Error': 'Caanot persist current song info to database'}, status=status.HTTP_406_NOT_ACCEPTABLE) return Response(dict_song_info, status=status.HTTP_200_OK) Besides fetching song info and rendering to the frontend, I also need to update song name data in DB before rendering. My question is: this function involves data update (no create new entries, just update existing data record). Does it still count as "Get"? Or actually, I should use "PUT" for this function? -

Django's form unique_together validation

How to filter in django with empty fields when using ChoiceField
I have a programme where users should be able to filter different types of technologies by their attributes. My question is, how would I filter the technologies when there's potential conflicts and empty values in the parameters I use to filter? Forms.py: class FilterDataForm(forms.ModelForm): ASSESSMENT = (('', ''),('Yes', 'Yes'),('No', 'No'),) q01_suitability_for_task_x = forms.ChoiceField(label='Is the technology suitable for x?', choices=ASSESSMENT, help_text='Please select yes or no', required=False,) q02_suitability_for_environment_y = forms.ChoiceField(label='Is the technology suitable for environment Y?', choices=ASSESSMENT, help_text='Please select yes or no', required=False) There are many fields in my model like the ones above. views.py class TechListView(ListView): model = MiningTech def get_queryset(self): q1 = self.request.GET.get('q01_suitability_for_task_x', '') q2 = self.request.GET.get('q02_suitability_for_environment_y', '') object_list = MiningTech.objects.filter(q01_suitability_for_task_x=q1).filter( q02_suitability_for_environment_y=q2) return object_list The difficulty is that not all technology db entries will have data. So in my current setup there's times where I will filter out objects that have one attribute but not another. For instance if my db has: pk1: q01_suitability_for_task_x=Yes; q02_suitability_for_environment_y=Yes; pk2: q01_suitability_for_task_x=Yes; q02_suitability_for_environment_y=''; In the form, if I don't select any value for q01_suitability_for_task_x, and select Yes for q02_suitability_for_environment_y, I get nothing back in the queryset because there are no q01_suitability_for_task_x empty fields. Any help would be appreciated. I'm also ok with restructuring everything if … -

Download a file after saving a model in Django
I'm trying to generate a PDF based on a ModelForm using Weasyprint. The idea is when the user clicks save the PDF is generated after the model is saved (I'm using the signal post_save to accomplish this). But when I hit the save button, the model is saved but the download prompt is not shown to the user, even though I have the correct Content-Disposition configuration in my HttpResponse. I also need to pass some parameters to the post_save signal because some of the fields that need to be added to the PDF are not in the Model, but are in the ModelForm, and I have not been able to find out how to do that. admin.py def save_model(self, request: HttpRequest, obj: Contract, form: ContractForm, change: Any) -> None: if not change and not request.user.is_superuser: obj = MythLabsMultiTenancy.assign_organization_to_obj( obj, request.user ) return super().save_model(request, obj, form, change) forms.py from dal.autocomplete import ModelSelect2 from django import forms from django.core.validators import RegexValidator class ContractForm(forms.ModelForm): class Meta: widgets = { 'handover_vehicle': ModelSelect2( url='vehicle_autocomplete', forward=('organization',), ), 'lease_holder': ModelSelect2( url='client_autocomplete', forward=('organization',), ), 'replacement_vehicle': ModelSelect2( url='replacement_vehicle_autocomplete', forward=('organization',), ), } warranty_card_company = forms.CharField(required=False, label='Tarjeta') warranty_card_number = forms.CharField( max_length=19, required=False, label='N° de tarjeta' ) warranty_card_expiration_date = forms.CharField( max_length=5, required=False, … -

Django APITest case not returning anything in get request
I am developing an API with Django, and I also want to test it, but I am having some trouble doing that. I need to test that to a given URL, what is returned is what I expect, and I want to do so with APITestCase of django rest framework.

I know that after that I have to query the db to check and use self.assertEqual, but for now my problem is retrieving data via get Maybe it is only a problem of settings.

How to check if a object has ManyToMany reference in a queryset django?

I think it can be done with these quersets:- all_questions = Question.objects.all() completed_questions = Question.objects.filter(profile = profile_instance) where profile_instance is a profile object. Then we can loop through the all_questions and check whether they also exist in completed_questions, but i am not sure whether this is optimized for pagination.
