How to deal with double foreign keys in Django while creating an API?
I created these models for my database. It's supposed to be kind of a tree (country>multiple cities>multiple airports). The problem is I want to use autocomplete which would show not only the name of an airport and the name of the city, but also the name of the country. I'm stuck because I don't know how to add the country to my API (together with airports of course). Is there a way to do it or maybe I should change the architecture of my database? class Country(models.Model): name = models.CharField(max_length=100) def __str__(self): return self.name class City(models.Model): name = models.CharField(max_length=120) country = models.ForeignKey(Country, on_delete=models.CASCADE) def __str__(self): return self.name class Airport(models.Model): name = models.CharField(max_length=150) abbr = models.CharField(max_length=4) city = models.ForeignKey(City, on_delete=models.CASCADE) country = city.country #how can I do this? def __str__(self): return self.name + ' (' + self.abbr + ')' from serializers.py: class AirportSerializer(serializers.ModelSerializer): city = serializers.StringRelatedField() class Meta: model = Airport fields = ['name', 'city'] from views - creating custom search API: class AirportList(generics.ListAPIView): serializer_class =AirportSerializer def get_queryset(self): airport = self.kwargs['airport'] list_airports = Airport.objects.filter(name__icontains = airport) return list_airports Path in case it's helpful: re_path('^airports/(?P<airport>.+)/$', views.AirportList.as_view()), script for autocomplete: <script> new Autocomplete ('#autocomplete', { search: input=>{ console.log(input) const url = `/airports/${input}/` return … -

Django, multiple DB hits when repeating one related query

Customized Login site not showing in Django
I have created a Django App and want to provide a custom Login page with only the possibility to use a Google login. I have implemented the Google login based on this post: https://www.section.io/engineering-education/django-google-oauth/ It actually works fine and when I hit localhost/account/login I am getting a login page: I actually do not want a sign up and a "local" sign in option, I only need a Google login. To achieve this I have created the following folder structure to overwrite the login template (based on https://learndjango.com/tutorials/django-login-and-logout-tutorial): MyApp/templaltes/registration/login.html login.html has the following content: {% extends "base.html" %} {% load i18n %} {% load socialaccount %} {% block content %} <div class="row"> <center><h1>{% trans 'LoginHeading' %}</h1></center> </div> {% if user.is_authenticated %} <p>Welcome, You are logged in as {{ user.username }}</p> {% else %} <a href="{% provider_login_url 'google' %}">Login With Google</a> {% endif %} {% endblock %} I have also added 'DIRS': [str(BASE_DIR.joinpath('templates'))] to the TEMPLATES section in settings.py. Unfortunately I am still seeing the Django default login page. What am I missing? (I have also restarted the dev server to make sure it is not an issue there with the same result) -

Using a for loop with Mapbox
I want to do what is done in this example: https://docs.mapbox.com/mapbox-gl-js/example/popup-on-hover/ but instead of adding each point manually i want to insert the data from my forms in a for loop. I have been succesful with using for loops to add markers in this format: {% for markers in marker %} {% if markers.PlantName in Bær %} var marker = new mapboxgl.Marker({ color: 'red'}) {% elif markers.PlantName in Frugt %} var marker = new mapboxgl.Marker({ color: 'orange'}) {% else %} var marker = new mapboxgl.Marker({ color: 'green'}) {% endif %} .setLngLat([{{ markers.lon }}, {{ markers.lat }}]) .setPopup(new mapboxgl.Popup().setHTML("<p>{{markers.PlantName}}<p>")) .addTo(map); {% endfor %} But in the example they add the points differently.

How to create a rest api with nested url in a DRY fashion?
I am trying to write a simple Geocache application. The backend access should work as follows: One Geocache Object contains general information (like creation date or difficulty level) but also several instructions, which have a fixed order (example instruction: Go first to coordinate lon/lat). The general URL structure is example.com/geocache/ List view for geocaches (get) example.com/geocache/<geocache_pk>/ Detail view for geocache (get/post/put/delete) (all instructions should be collectively displayed here but they cannot be manipulated here) example.com/geocache/<geocache_pk>/instruction/ Only to create new instructions (post) example.com/geocache/<geocache_pk>/instruction/<instruction_position/> Only for instruction manipulation/deletion (put/delete) I tried to accomplish this structure through custom actions with regular expressions in the url_path but I feel it is not DRY enough. I am learning Django only for a few days so I might be missing some sophisticated patterns. Please also let me know if the general approach makes sense to you. Thank you for your effort!
