Search input not rendering- no errors - stuck

Kanatbek-AKA · May 27, 2023, 11:53pm

Hi all,

Can someone please help me to understand what wrong is with the code below? Actually it is working, but if I try to render the second db QuesAnswer searching for/by question, it is not displaying or throwing an error. Although by debugging or using shell I see there is the expected output to display on front-end.

Here is my view.py

class MainPageView(TemplateView):
    model= Definitions
    # template_name = "encyclopedia/draft.html"

    def get(self, request):
        # Get inputs value
        queryOne = request.GET.get('QuizOne')
        queryTwo = request.GET.get('QuizTwo')
        queryThree = request.GET.get('QuizThree')
        #
        if queryOne:
            def_output = Definitions.objects.filter(
                Q(term__icontains=queryOne) | Q(term__contains=queryOne)
                )
            ques_output = QuesAnswer.objects.values().filter(
                Q(question__icontains=queryOne) | Q(question__contains=queryOne)
                )
            # print(ques_output)
            return render(request, 'encyclopedia/draft.html', {'def_object': def_output, "ques_object": ques_output})
        elif queryTwo:
            def_output = Definitions.objects.filter(
                Q(term__icontains=queryTwo) | Q(term__contains=queryTwo)
                )
            ques_output = QuesAnswer.objects.values().filter(
                Q(question__icontains=queryTwo) | Q(question__contains=queryTwo)
                )
            # print(ques_output)
            return render(request, 'encyclopedia/draft.html', {'def_object2': def_output, "ques_object2": ques_output})
        elif queryThree:
            def_output = Definitions.objects.filter(
                Q(term__icontains=queryThree) | Q(term__contains=queryThree)
                )
            ques_output = QuesAnswer.objects.values().filter(
                Q(question__icontains=queryThree) | Q(question__contains=queryThree)
                )
            # print(ques_output)
            return render(request, 'encyclopedia/draft.html', {'def_object3': def_output, "ques_object3": ques_output})

        return render(request, 'encyclopedia/draft.html', {})

The only problem is that if I search by question to get the explanation, answer etc, it does not render anything on front-end.

By the way, buttons are disabled here.

Thanks in advvance.

Kind regards,
Kanatbek

Why the buttons are disabled, search input needs a search button to be clicked, So if disabled you will get NOTHING

Kanatbek-AKA · May 28, 2023, 1:14pm

Hi cehceh,

Buttons in this sample code do not do anything therefore they are disabled. By the way, thanks for noticing it.

Kind regards,
Kanatbek

cehceh · May 28, 2023, 1:27pm

You are welcome

Another thing I can notice “ques_output” will produce a dictionary because you use .values()
Try to remove it and look if it works .

Kanatbek-AKA · May 28, 2023, 1:30pm

I tried it by removing values() as well as tried by adding f-string e.g. Q(question__icontains = f’{queryOne}’ - both failed - no errors and renders.

cehceh · May 28, 2023, 4:32pm

Try to make a context variable then pass it to the last render

if ('QuizOne' in request.GET) and request.GET['QuizOne'].strip():
...
context = {'def_object': def_output, "ques_object": ques_output}

elif queryTwo:
...
context = {'def_object2': def_output, "ques_object2": ques_output}

As the following

return render(request, 'encyclopedia/draft.html', context=({} | context))

I think your variables didn’t pass to the templates

Also try this for all queryOne , Tow and Three

if ('QuizOne' in request.GET) and request.GET['QuizOne'].strip():

Hope this helps

Kanatbek-AKA · May 29, 2023, 1:07am

Thanks cehceh for the effort and your answers,

I used your suggestion and the result is the same, searching for term renders the output, but not for questions. I think I am going to convert values() dict output to string to display.

Kind regards,
Kanatbek

cehceh · May 29, 2023, 5:05am

Okay, I wish to fix your issue and find what you are looking for.

But for debugging

Use (print()) in your views.py to know if your variables produce values or return empty
Also print the passing variables in your templates directly without nested for loop

In order to see what is going on .

Good luck
