How to send dynamic ID info from django class-based view to formset
I have a class-based view that renders a formset based on the project selected. Each project has a unique project_id. I get a 404 error caused by Line 14(below) in views.py if don't hard-code the project_id (ie '4') to replace 'None'.Also,the formset doesn't load if i don't hard-code the project_id in Line 4 under forms.py. Since the project_id needs to be passed automatically,how can i get it updated and passed into the formset? Thanks. I tried this: views.py class ReqView(CreateView): template_name = "req_view.html" model = ProjectBudgetReq form_class = ReqForm def get_form_kwargs(self,*args, **kwargs): form_kwargs = super(ReqView, self).get_form_kwargs(*args, **kwargs) form_kwargs['project_id'] = self.kwargs.get('project_id') print("get_form_kwargs:",form_kwargs) return form_kwargs def get_context_data(self,**kwargs): project_id = kwargs.pop('project_id',None)#Line 14 404 Error project = get_object_or_404(ProjectDetails,id=project_id) formset = ReqFormSet(instance=project) context = super(ReqView, self).get_context_data(**kwargs) context['project'] = project context['formset'] = formset return context def get_context_kwargs(self,**kwargs): context_kwargs = super(ReqView,self).get_context_kwargs(*args,**kwargs) context_kwargs['project_id'] = self.kwargs.get('project_id') return context_kwargs forms.py class CreateReqForm(forms.ModelForm): def __init__(self,*args,**kwargs): project_id = kwargs.pop('project_id',None) #Line 4 Formset not rendered super(CreateReqForm,self).__init__(*args,**kwargs) self.fields['proj_name'].queryset = ProjDesc.objects.filter(id=project_id) self.fields['budget_desc'].queryset = ProjBudget.objects.filter(proj_name_id=project_id) class Meta: model = ProjBudgetReq fields = '__all__' BudgetReqFormSet = inlineformset_factory(ProjDesc, ProjBudgetReq, form=CreateReqForm, fields='__all__',extra=2) Issues: views.py #Line 14: 404 Error since it returns 'None' forms.py #Line 4: Formset does not render, since it's 'None' -
Using Python, I want to check the data that is Type_Of_Wallet is already exists in my MySQL database table or not?
I am new to Django where I designed an application where I created a form in templates and used a database that is in localhost/PHPMyAdmin. Now when the user enters the data in given fields and presses the submit button, it should check in the database whether the given data is present in the database or not. But my code is not working. `views.py import mysql.connector from django.http import HttpResponse from django.template import loader from django.views.decorators.csrf import csrf_exempt @csrf_exempt def index(request): if request.method == 'POST': Type_Of_Wallet = request.POST.get('Type_Of_Wallet') BLE_MAC_ID = request.POST.get('BLE_MAC_ID') BAR_CODE = request.POST.get('BAR_CODE') Version = request.POST.get('Version') context = { 'Type_Of_Wallet': Type_Of_Wallet, 'BLE_MAC_ID': BLE_MAC_ID, 'BAR_CODE': BAR_CODE, 'Version': Version, } template = loader.get_template('valid_form/showdata.html') return HttpResponse(template.render(context, request)) else: template = loader.get_template('valid_form/index.html') return HttpResponse(template.render()) mydb=mysql.connector.connect( host = 'localhost', user = 'rajat', passwd = 'rajat', database = 'MyForum' ) mycursor=mydb.cursor() print('Enter Type_Of_Wallet:') Type_Of_Wallet=Input(context) CheckType_Of_Wallet=mycursor.execute( 'SELECT Type_Of_Wallet FROM form_simpleform WHERE Type_Of_Wallet=%(Type_Of_Wallet)s', {'Type_Of_Wallet':Type_Of_Wallet}) if CheckType_Of_Wallet !=0: print('Type_Of_Wallet does not exit') else: print('Its Available') ` index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Validation</title> </head> <body> <h2>Validation</h2> <form method="post" action="/getdata/"> <table> <tr> <td>Enter Wallet Type:</td> <td><input type="text" name="Type_Of_Wallet"/></td> </tr> <tr> <td>Enter your BLE_MAC_ID:</td> <td><input type="varchar" name="BLE_MAC_ID"/></td> </tr> <tr> <td>Enter your Bar Code:</td> <td><input type="varchar" name="BAR_CODE"/></td> </tr> <tr> … -

Slug generator don't generate slug for tablecontent

Average duplicates from specific columns in QuerySet in Django
I have a Django Model I am using that looks like this: class FinancialAid(models.Model): RECEIVED_EVERY = (("J", "Jours"), ("S", "Semaines"), ("M", "Mois")) ID = models.AutoField(primary_key=True) Name = models.CharField(max_length=100, null=True, blank=True) Value = models.IntegerField(null=True, blank=True, default=-1) ReceivedEvery = models.CharField(max_length=15, null=True, blank=True, choices=RECEIVED_EVERY) Exchange = models.ForeignKey('Exchange', on_delete=models.CASCADE) I am able to access the information I want but I have an issue in that I often have duplicates within my QuerySet over the Name and ReceivedEvery columns but not always on the Value and never on the Exchange. Say I have the following QuerySet expanded out: financial_aid_qs = [ (ID=1, Name="Aid1", Value=100, ReceivedEvery="M", Exchange=Exchange.objects.get(pk=1)), (ID=2, Name="Aid2", Value=200, ReceivedEvery="S", Exchange=Exchange.objects.get(pk=2)), (ID=3, Name="Aid1", Value=150, ReceivedEvery="M", Exchange=Exchange.objects.get(pk=3)), (ID=4, Name="Aid3", Value=100, ReceivedEvery="M", Exchange=Exchange.objects.get(pk=4)) ] As you can see, I have the same Name and ReceivedEvery for indexes 1 and 3. What I would like to do is get a QuerySet (or ValuesQuerySet although I seem to recall this was removed) that will contain all the different FinancialAid objects in terms of Name and average out the Value of FinancialAid objects that have the same Name. Ideally it would take into account the fact that ReceivedEvery can differ even though the Name is the same (This is all … -
Making generated emails 'outlook friendly'
I'm using Summernote as a WYSIWYG editor for users to create emails and send them within a django application. As it stands it works perfectly well in most clients which handle HTML in any normal way, however when the mail is sent to outlook it goes awry. Essentially Summernote is using style="float: x width: x" which outlook is simply ignoring, then rendering the image that should be floated right or left wherever it has been placed and at full size. Does anyone know of a package that can parse the generated summernote HTML and make it Outlook friendly before I go ahead and start writing up a whole lot of string replacements in the generated HTML? -
How to import the data from a data dump (SqLite3) into django?
I have a data dump file(.sql) containing certain data, I would like to import it to my database(currently Sqlite3 but thinking about changing to MySQL) in order to use it in my test website. Also, I need to know if it's possible to add the models too automatically, I presume it needs to be added manually, but any how, if there is any way to solve it, please suggest it. -
Search Marker Leaflet Map
I am working on an application with Django. There in this application, I am first using Django to create a database with points and extract a JSON file (It is called "markers.json"). Then, using this JSON file, I am creating markers on a map with Leaflet. When I finished entering all the points to the database they will be around 5000 thousand. So, I decided that it is a good idea to be able to search this markers with an input tag and a search button. I enter the "site_name" as input and when I click the "search" button the related marker should popup. However, always the same marker pops up and I don't know where I am doing wrong.

Annotating average and count of latest instances created by one author
So, I've got that piece of code: def generate_annotated_applications(queryset): return queryset.annotate( avg_rating=Avg( 'application_ratings__rate', distinct=True, filter=Q(application_ratings__job_process_step__job_process__job=F('job')), ), ).annotate( num_ratings=Count( 'application_ratings', distinct=True, filter=Q(application_ratings__job_process_step__job_process__job=F('job')), ) In general it works well, but the problem is that avg_rating is counted from every existing application_ratings. What I need to achieve is to count average taking only latest ratings with unique author. There are many instances of application_rating with different rate and author. Same thing is with num_ratings - I need to count number of latest ratings with unique author field. -

Python: Passing an object instance from one function to another?
I'm having trouble with passing a value from one script to another, trying to take it a step at a time but the big picture would be to print the value obj1.get_predval to my Django view and wait for the users' input. active_learner.obj1.get_predval in my beta.py script doesn't work, it just prints out the initial value which makes sense because it's not running the main.py but I'm not sure how I'd pass the value of obj1.set_predval(machine_prediction) from main.py. It properly outputs the obj1.get_predval in the main.py script. I'm assuming I have a fundamental misunderstanding, for now, all I'm trying to return is the value of obj1.get_predval in function beta.py, when it gets to the line return value and wait for user input then continue. main.py script below obj1 = MachinePred() def main(): model = load_model('model_new.h5') DATAFILE = "c_user_model_data100000.csv" dataset = loadtxt(DATAFILE, delimiter=",") X_pool, Y = dataset[:, 0:5], dataset[:, 5:] sc_x, sc_y = StandardScaler(), StandardScaler() X_pool, Y = sc_x.fit_transform(X_pool), sc_y.fit_transform(Y) learner = ActiveLearner( estimator = model, query_strategy = uncertainty_sampling ) for i in range(3): query_idx, query_inst = learner.query(X_pool) print("The machine queried:\n{}\nat index {}".format( sc_x.inverse_transform(query_inst), query_idx ) ) machine_prediction = learner.predict(X_pool[query_idx]) obj1.set_predval(machine_prediction) print("predvalue:", (obj1.get_predval())) ratings = [] cc_factor = ["delay", "speed", "missing_words", … -

How to create a validation check that ensures the right-formatted directory path is stored and if it contains a file extension in Django?
I have a template that allows a user to store a pathname of a directory in my model (the directory should be available/exist in the server for a website or seen in a local machine). Before saving the path to the model, I need to ensure whether if the right format for the directory is being saved. Example: var/www/html/media/product or C:\Users\Danny\Desktop\folder. There shouldn't be any irregular strings, expressions or invalid format seen in the path like var/www/html/media/product\pic/... Moreover, I want to stop users if they want to save a specific directory path that contains a file extension. Example: var/www/html/media/product/file.<'file extension'> ('file.png', top.txt', 'random.jpg', etc...) How can this be done in my views.py code? Currently, this is what I did so far: views.py: def dashboard(request): if request.method == 'POST': form = PathForm(request.POST) if form.is_valid(): path = form.cleaned_data['path'] #CharField that stores the path name in model from form. #Two checks required. Need to see if it is a valid directory path format or if the path contains a general path directory. Not specific files (like images, text, csv file) should be seen in the path. #if file path contains a file extension at end. This is tedious since I need include all … -
