Python - Multiple type users with custom user model in django-allauth
I'm working on a project using PythoN(3.7) & Django(2.2) in which I have to create 4 different types of users with different fields but they will share some common fields like title & name etc. But I also need to use email as the username and need to provide different signup form but one login form.

Django 2.1.5 migration does not happen with makemigrations command
In our Django project(Django 2.1.5), every time we try to run the project we have to give the '--noreload' command in addition to the runserver command, else the project returns an error as, ValueError: signal only works in main thread We are using Django signals to communicate between the apps created in Django and Web-sockets in Threading aysnc-mode to connect between the other services involved in the project. When we try to deploy the project in Jenkins, this becomes a problem and we are using Nginx as the webserver for host the application. Is there any possibility to solve the issue of '--noreload' and run the application normally? We are not sure if its because of the same problem referred above but we have a problem when trying to migrate the changes in the Models in Django, it always returns No changes Detected After a quick internet search, we did the migrations by mentioning the app names and it did work, yet the terminal stays still after the migrating and waits to manually terminate the process. Is there a possible solution to overcome this? and also we would like to know where we go wrong -
Python/Django filter rows with max value in a group
I saw multiple answers on this, but none of the suggested solutions helped me. Model describes production plans for various units. Production plans are updated hourly. Each production plan is called 'layer' as they 'stack' upon each other during the day. Naturally, next 'layer' is one hour shorter than previous. Model is as follows: class PlanData(models.Model): plan_type = models.ForeignKey(PlanType, on_delete = models.CASCADE) # we only need type 2 here plan_ident = models.ForeignKey(ObjectConfig, on_delete = models.CASCADE) # decribes production unit plan_for_day = models.DateField() # the day of production cycle layer = models.IntegerField(null = True) #'layer' production plan from specified hour to then of the day. # layer 1 contains 24 values, layer 10 - 14 values hour = models.IntegerField() # hour of production val = models.FloatField(blank = True, null = True) # how much the unit should produce at that hour What I need is to filter PlanData by getting those where layer is maximum by grouping by plan_ident and hour. What I'm trying to do could be done in SQL like select a.plan_ident, a.hour, a.layer, a.val from dbo.asbr_plandata a inner join ( select max(layer) 'mlayer',plan_ident_id, hour from dbo.asbr_plandata where datediff(day,plan_for_day,getdate()) = 0 and plan_type_id = 2 and plan_ident_id in (24) … -
Why file upload is not working in Django after directed from other url?
I want to do a simple web applications to let user to choose a task, where one of the tasks require file upload. In home, user is prompted to select task 1 or 2. After 2 is selected, it will enter another page to prompt user to upload file. I tried to follow a tutorial online for file upload but it does not work the way I wanted. In views.py, I have the following functions: def home(request): return render(request,'home.html') def choice(request): name1=request.GET['name_1'] name2=request.GET['name_2'] if request.GET['choice']=='1':return render(request, "train.html",{"name1":name_1, "name2":name_2}) elif request.GET['choice']=='2':return render(request, "train.html",{"name1":name_1, "name2":name_2}) def predict(request): if request.method=="POST": document=request.FILES['document'] print(document.name) print(document.size) return render(request,'predict_home.html') For the urlpattern in urls.py, urlpatterns=[ path('',views.home,name='home'), path('choice',views.choice, name='choice'), path('predict',views.predict,name='predict'), ] The home.html is to prompt user to select task: <h2>Select a Task:</h2> <form action="choice"> <select name="choice"> <option value="1" selected >Train new model</option> <option value="2" >Prediction</option> </select> <br><br> System 1 is used to predict system 2 <br> Enter the name of system 1:<br> <input type="text" name="name1"><br> Enter the name of system 2:<br> <input type="text" name="name2"><br> <input type="submit"> </form><br><br> </form> The predict.html is the GUI to prompt user to upload file: <br><h3>{{name_1}} is used to predict {{name_2}}</h3> Upload profiler logs:<br> <form method="post" enctype="multipart/form-data"> {% csrf_token %} <input type="file" name="document"><br><br> … -
How to serialize update on DRF with a modified listField
I have a serializer like this: class Serializer(serializers.ModelSerializer): main_field = ListField(child=serializers.CharField(), required=True) fields = ( "main_field", "field_a", "field_b", "field_c", ) def update(instance, validated_data): data = deepcopy(validated_data) instance.filter(main_field=data.pop("main_field")).update(**data) return validated_data The thing is that when i update, then i call this return on my view: return Response(status=status.HTTP_200_OK, data=serializer.data) that's when serializer.data fails to be called because it was expecting all the fields, not just the partial ones. logic: When i update i have to update all the fields on the rows called by the main_field list. So all of them should be grouped by the main_field list with the same other fields. im using django 1.11 (can not do anything about that tbh). -
