django jQuery AJAX Autocomplete
I set an autocomplete field like bellow but its not working :( Is there any problem in it? import jQuery and jQuery UI: <script type="text/javascript" src="{% static 'js/jquery-1.12.4.min.js' %}"> </script> <script type="text/javascript" src="{% static 'js/jquery-ui.min.js' %}"> </script> <link rel="stylesheet" type="text/css" href="{% static 'css/jquery-ui.css' %}"> In html template: <div class="ui-widget"> <label for="places">Places: </label> <input id="places"> </div> and : <script> $(function() { $("#places").autocomplete({ source: "/api/get_places/", select: function (event, ui) { //item selected AutoCompleteSelectHandler(event, ui) }, minLength: 2, }); }); function AutoCompleteSelectHandler(event, ui) { var selectedObj = ui.item; } </script> In url.py : url(r'^api/get_places/', views.get_places, name='get_places'), in views.py : def get_places(request): if request.is_ajax(): q = request.GET.get('term', '') places = Place.objects.filter(city__icontains=q) results = [] for pl in places: place_json = {} place_json = pl.city + "," + pl.state results.append(place_json) data = json.dumps(results) else: data = 'fail' mimetype = 'application/json' return HttpResponse(data, mimetype) when i add print(places) in view, it works and returns correct fields from database based on the letter i entered in the textbox . so the problem is in the sending and receiving json data which it return! -

How to rate objects programmatically in Django Star Rating
I am using this library : django-star-rating to rate model objects by scores given by users. You can view the documentation here Problem that I face: How can I rate an object programmatically in view function rather than in the template. Also how can I integrate it with Django Rest framework? It uses a generic relation in the model schema. So far, I have used the field as Serializer Method field but the problem with that is that it is read only and the client cannot make patch request to update rating. Code so far: from star_ratings.models import Rating class ExampleModel(models.Model): rating = GenericRelation(Rating, related_query_name='example') from rest_framework import serializers class ExampleSerializer(serializers.HyperlinkedModelSerializer): rating_total = serializers.SerializerMethodField() rating_count = serializers.SerializerMethodField() class Meta: model = ExampleModel fields = '__all__' def get_rating_total(self, obj): if obj.rating.exists(): return obj.rating.first().total else: return 0 def get_rating_count(self, obj): if obj.rating.exists(): return obj.rating.first().count else: return 0 From drf docs : SerializerMethodField This is a read-only field. It gets its value by calling a method on the serializer class it is attached to. It can be used to add any sort of data to the serialized representation of your object. Hence the field is read only and I can't rate it from … -
django with react using web pack
I have added react js in django using webpack loader WEBPACK_LOADER = { 'DEFAULT': { 'BUNDLE_DIR_NAME': 'bundles4/', 'STATS_FILE': os.path.join(BASE_DIR, 'webpack-stats.json'), } } First time all things are OK.

Django blog deployment - server error 500
I have a simple blog project hosted on PythonAnywhere. When I go to my domain www.nomadpad.io I get "Server Error 500" From the error log below, it appears to be something to do with my editedimage field, which looks like this in my models.py : editedimage = ProcessedImageField(upload_to="images", blank=True, null=True, processors = [Transpose()], format="JPEG") This all works fine in my development environment, and I can run collectstatic on both versions.

Django populate from from model
Django 2.0.2 Python 3.6.3 Hi, I am still trying to learn Python by jumping head first into a django project. I have a "profile" model that extends the "user" model.

Django Docker/Kubernetes Postgres data not appearing
I just tried switching from docker-compose to docker stacks/kubernetes. In compose I was able to specify where the postgres data volume was and the data persisted nicely. volumes: - ./postgres-data:/var/lib/postgresql/data I tried doing the same thing with the stack file and I can connect to the pod and use psql to see the schema but none of the data entered from docker-compose is there.

Dynamic search form using javascript for Django project
I am trying to create a search form using jquery for Django using following tasks to do: A user can upload file or input text into the text area or select option from the drop-down menu but these options will appear based on the selection of 1st drop-down menu. The user can clone this form number of times but not more than max options of 1st drop-down menu. The user can remove form < max options of the 1st drop-down menu. Once submit button will be pressed, it will check form validity then send information to Django. But problems are: Task 1 is working only on 1st form but not in cloned one. My Django views only get information about textarea and selected option but not the content of uploaded file which shows nothing in a file. views.py def fileupload(request): if request.method: print "Hello" try: print request.GET['cityname'] except MultiValueDictKeyError: pass try: print request.GET['listofcompany'] file = request.FILES['foofile'].read() print file except MultiValueDictKeyError: pass try: print request.GET['runprogram'] except MultiValueDictKeyError: pass var max_fields = 3; //maximum input boxes allowed var wrapper = $(".input_fields_wrap"); //Fields wrapper var addButton = $("#form-add"); //Add button ID var form = $('#main-form'); var x = 1; //initlal text box count … -
Django not passing data to the post method

Django concurrent write issue within transaction.atomic()
class ChampionStats(models.Model): champ_id = models.IntegerField(primary_key=True) total_games = models.IntegerField(default=0) with transaction.atomic(): champ_stats, created = ChampionStats.objects.select_for_update().get_or_create(champ_id=champ_id) champ_stats.total_games += 1 champ_stats.save() I have multiple celery tasks running concurrently on the code above and sometimes occasionally I have multiple objects being returned. api.models.MultipleObjectsReturned: get() returned more than one ChampionStats -- it returned 2! To my understanding if I am running get_or_create in an atomic context then one task will create the table and set a lock on it, throwing an integrity error on all further creates on the same row, thus calling get() instead. -

Updating model instance dynamically with django
I am stuck in this, i have this api that is made initially by a POST method then a PATHCH method gives it some previously nulled fields and closes this particular session. So far so good but the thing is that the poster and patcher of the API is a electronic device that given some particular circumstances fails to send the PATCH or POST as well, the thing is that there is not possible to be more than one session opened for any given instance, so what i need is when there comes a POST and the PATCH has not closed the current opened session the big idea is to force the update method for that instance and give the fields (nulled ones) the values of the POST that is trying to create a new session. Hope i 've had made myself clear. Here the code class MyModel(models.Model): session_initial_timestamp = models.DatetimeField() some_field = models.ForeignKey(SomeModel) field1_initial = models.IntegerField() field1_final = models.IntegerField() session_final_timestamp = models.DateTimeField()" So as i explained before the POST method gives the initial timestamp and field1_initial and of course the related field. The PATCH gives the final timestamp and final1_field. Thanks in Advance. -
