Limit forms foreign key to a choices in related model
I am working on creating a form but stuck at this issue. I have several businesses in the Business Model. Each Business has its own Service in Services Model. The User is tied to only one Business.

axios get request depending on user data fails
I've setup an auth system with nuxtjs & django. However i do not understand nuxtjs completely <template> <div> {{ this.$auth.$storage.state.user.email }} </div> </template> <script> import axios from 'axios'; export default { } axios.get('/api/v1/is-success-or-not?email='+this.$auth.$storage.state.user.email) .then((response) => { if(response.data === "True") { console.log("Player is success") $nuxt.$router.push('/schedule') } }) axios.get('failureornot?email='+this.$auth.$storage.state.user.email) .then((response) => { if(response.data > 3) { console.log("failure") $nuxt.$router.push('/failure') } }) </script> This is my code I've the email that shows up with {{ this.$auth.$storage.state.user.email }} but when i try to adapt the get request depending on the user, i get this error Cannot read properties of undefined (reading '$auth') I do not understand because $auth is obviously define if i can print the value thanks for your help ! -
Django - Sqlite column names different from model field name
I've had a model with a field named enclosure_id. I changed the field name to enclosure_name in the model and everywhere in the code, since that seemed more appropriate to the content. Now the respective column in the db is called enclosure_name_id I do not understand how this name is created. And I'm not able to get rid of this. I've deleted the database (I'm still at a testing phase) and all migrations, it's always regenerated as enclosure_name_id. Nowhere in my entire code is there an occurence of enclosure_name_id. If anyone could help me out, this would be great. Best regards, Gero -
How to serialize multiple models in on serializer with Django?
I try to combine multiple serializers into 1 so I don't have to do multiple fetch on the front end for the same page. Seems that I must use SerializerMethodField. My views is quite simple : @api_view(['GET']) def get_user_profile_by_name(request, name): try: user_profile = UserProfile.objects.get(display_name=name.lower()) serializer = UserProfileSerializer(user_profile, many=False) return Response(serializer.data) except ObjectDoesNotExist: message = {'detail': 'User does not exist or account has been suspended'} return Response(message, status=status.HTTP_400_BAD_REQUEST) As this can be accessed by Anonymous user, I can't use request.user All models I want to access inside UserProfileSerializer are related to UserProfile. So I dont really know how to setup my serializer. ( I have more serializer to combine but I limited this to one serializer inside the serializer for the example ) class UserProfilePicture(serializers.ModelSerializer): class Meta: model = UserProfilePicture fields = '__all__' class UserProfileSerializer(serializers.ModelSerializer): profile_picture = serializers.SerializerMethodField(read_only=True) class Meta: model = UserProfile fields = '__all__' def get_profile_picture(self, obj): # What to do here ? I struggle to understand how to acces " user_profile " object from UserProfileSerializer in order to query the right UserProfilePicture object and return the data combined inside UserProfileSerializer. -
