I'm trying to implement a live search through the jquery plugin Select2 in my Django 1.11.4 project. Running Python 3.6. When I type in the textbox, the server doesn't seem to be able to handle the number of requests and it closes, followed by these series of errors. I've spent a couple hours following a couple threads on SO SO(more) , Google, etc but none have a working solution. I thought it was a python version issue, but I've upgraded from 2.7 to 3.6 and still have it. Any help would be great thanks!
This the view that's being called by the ajax call:
def directory_search(request):
# Query text from search bar
query = request.GET.get('q', None)
if query:
# Searches the DB for matching value
customers = Customer.objects.filter(
Q(name__icontains= query)|
Q(contract_account__icontains= query)|
Q(address__icontains= query)|
Q(address__icontains= query)|
Q(email__icontains= query)
).distinct()
# Turns queryset into dict
customers = customers.values("contract_account","name")
# Turns dict into list
customers_list = list(customers)
return JsonResponse(customers_list, safe=False)
else:
return JsonResponse(data={'success': False,'errors': 'No mathing items found'})
This is the js/ajax call for the Select2 plugin:
$(".customer-search-bar").select2({
ajax:{
dataType: 'json',
type: 'GET',
url:"{% url 'portal:directory_search' %}",
data: function (params) {
var queryParameters = {
q: params.term
}
return queryParameters;
},
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
id: item.contract_account
}
})
};
}
},
escapeMarkup: function (markup) { return markup; },
minimumInputLength: 1,
templateResult: formatRepo,
templateSelection: formatRepoSelection,
language: { errorLoading:function(){ return "Searching..." }}
});
Errors: (I just broke them apart to make it more legible, but they occurred in the presented order)
