django Query filter

[Abhineet Baranwal]

this is my views file which creates an error like  django.utils.datastructures.MultiValueDictKeyError: 'search1' . Can anyone tell me where i go wrong?

def viewstr(request):

    views = create_store.objects.all()
    brn = Prod_Brand.objects.all()
    mi = ''
    if request.method == 'POST':
        # mi = ''
        search1 = request.POST['search1']
        if search1 == '' :
            pass
        else:
            mi = create_store.objects.filter(Q(select_brand__Brand__icontains=search1))
            if mi:
                return render(request,'viewstr.html',{'vi':mi,'brn':brn})
        search = request.POST['search']
        if search == '' :
            pass
        else :
            mi = create_store.objects.filter(Q(id__icontains=search))
            if mi:
                return render(request,'viewstr.html',{'vi':mi,'brn':brn})

    return render(request,'viewstr.html',{'viewstr':viewstr,'vi':mi,'brn':brn})

Hi Abhijeet baranwal,

seems like search1 key is containg multi value dictionary and you are checking it with == which is for single value

after          

search1 = request.POST['search1']      

put  

print( search1  )

return "hello"

 and comment code remaining below ,check terminal it will show you how many value you have in dictionary

Hi abhineet baranwal,

You have to use q(id__in=search) instead q(id__icontains=search) ..search more about how to use in query in django and 1 thing you are not getting correct post value of searc1

Your request.POST does not contain "search1".

Do so search1 = request.POST.get('search1')

Example:

def viewstr(request):

    views = create_store.objects.all()

    brn = Prod_Brand.objects.all()

    mi = ''

    if request.method == 'POST':

        search1 = request.POST.get('search1')

        if search1:

            mi = create_store.objects.filter(Q(select_brand__Brand__icontains=search1))

            if mi:

                return render(request,'viewstr.html',{'vi':mi,'brn':brn})

        search = request.POST.get('search')

        if search:

I edited it as you suggested but it is giving another error like 'method' object is not subscriptable

Thanks..I'll search for that but i think its not related to the query, its related to two search i have used in one post request

Thanks for the help, this is showing only one value in dictionary at a time . There is no fault here but i have a question can we run multiple search query in same page with different id ? And it shows that error even now

The global POST variable allows you to access the data sent with the POST method by input name. See more info https://developer.mozilla.org/en-US/docs/Learn/HTML/Forms/Sending_and_retrieving_form_data.

Your html:

<form action=".">

  First name:<br>

  <input type="text" name="search">

  <br>

  Last name:<br>

  <input type="text" name="search1">

  <br><br>

  <input type="submit" value="Submit">

</form>
