Make sure celery task exits after database commit
I have a Django application in which the app creates a celery task to process user input, check the progress of the task, and update the page as soon as the task is completed. I am well aware of the fact that the celery task should only be started after the record being processed is committed, using code such as transaction.on_commit(lambda: my_task.apply_async(args=(pk,))) However, when the task exits with something like @celery.task def my_task(pk): record = Record.objects.get(pk) # do something record.save() The django app still gets the old value of the record when it reads from the database (Record.objects.get(pk)), likely because the database has not been updated yet. How can I make sure that the celery task exits only after the transaction has been committed? I tried to add transaction.commit() after record.save() and it does not appear to help. -

Uploading image file from React Native to Django
So on the React Native side the console.log is printing this for the image file as in I'm doing console.log(image_file) and getting this {"fileName": "rn_image_picker_lib_temp_0d752f09-0fab-40f0-8c89-13dec3695de0.jpg", "fileSize": 374466, "height": 810, "type": "image/jpeg", "uri": "file:///data/user/0/com.cheersfe/c ache/rn_image_picker_lib_temp_0d752f09-0fab-40f0-8c89-13dec3695de0.jpg", "width": 1000} Here is my React Native Code const createFormData = (photos, body = {}) => { const data = new FormData(); if (photos.length > 1) { console.log(photos[1]) data.append("images", photos[1]); } Object.keys(body).forEach((key) => { data.append(key, body[key]); }); return data; }; const onAddButtonClick = () => { if (value === null) { Alert.alert("Hold On!", "Please select a goal"); } else if (descriptionText === "") { Alert.alert("Hold On!", "Update description required"); } setLoading(true); const body = createFormData(photos, { join_goal: value, body: descriptionText }); postGoalUpdatePost(body).then(response => { // navigation.navigate("PostsScreen"); setLoading(false); }).catch(error => { const errorMessage = `${error.name}: ${error.message}`; }); setLoading(false); }; export async function postGoalUpdatePost(body) { return constructConfig().then(config => { return axios.post(`${url}/posts/update`, body, config).then(response => { return response.data; }); }); } But on the Django side when I look at request.data['images'] I get this crazy hexstring: \x7f.x�������uJr|�����a=e��|�\x00��^�=J0�^������\x08\x1a\\\x02;�H�a�a�\x19=�u�K\x01�x䞧�\x0e�{{�\x07\x14���}H�2\x06?.)%�\x7f\x1f�\x0c�RvI������=H-���[��䌏ÿ^��\x00玵�$��<g�\x1d}�\x1d�\x00®7�\x1e���Yr\x7f�\x1f���+&��wт�I�?������$�Ӯz���N?Z�+�\x07�Oo\x7f�?����\x7f\x13���ܒ1����\r����V=J0M�\x7f5�I5�ϹVG���\x189��`�\x7fJ�$��u�1���{\x7f.�չ:7���kuO��\x15���m,����{\x18x�\x7f.]�\x7f�W��s�\x0e=��1�\x00֬�e^��0y$sӧ�\x0ez՛���\x7f3YS\x13��|��+�\x7f\x13��#���;>�k�o�\x7fñ\x1c�\x03�\x0f\x18�;s�\'��ߥ\x19$$�{���O���SI�\x1b�U\x1f�\x0f�O�\x15���}^����֥\x08���u���\x002��|����|���Y�$�\x003�^�A�9�>�j��\x1f����z\x1f��U��\x17�u=z\x10\\��O����b9�V\x18\x04p\x08������Vd�G\x1f��2O�V��\x1f�ک\\u?C��qԛJI[���zT"����_�W+�\x02\x06\x0f$u����\x00����\x15\x19�\x1f��4W\x0b��z$w���' so clearly it's coming in as a string rather than a file.

Recursive and nested serializer for CreateAPIView
I know there are a few other threads about this topic but none of the solutions seem to work for me. I have a simple django-treebeard model that allows me to bulk add nested children to a parent via a load_bulk model method. The POST payload is essentially: items = [ {"data": {"title": "1"}, children: []}, {"data": {"title": "2"}, children: [ {"data": {"title": "2_1"}, children: []}, {"data": {"title": "2_2"}, children: [ {"data": {"title": "2_2_1"}, children: []}, ]}, ]}, ] payload = { "parent_id": parent_id, "items": items } I have a view that takes the parent_id and the items list of objects from the payload and passes it to load_bulk to create all the nested objects: Model.load_bulk(items, parent=Model.objects.get(id=parent_id) It works fine for the top-level of items but seems to ignore the nested children. In fact, I can't even get the get_children method in my serializer (commented below) to run. # models.py class Item(MP_node): id = UUIDField() title = CharField() # views.py class BulkCreateView(generics.CreateAPIView): queryset = Item.objects.all() serializer_class = BulkCreateSerializer # serializers.py class BulkCreateSerializer__item(serializers.ModelSerializer): class Meta: model = Item fields = ["title"] class BulkCreateSerializer__wrapper(serializers.ModelSerializer): data = TextBulkCreateSerializer__chapter() children = serializers.SerializerMethodField() class Meta: model = Item fields = ["data", "children"] def get_children(self, obj): … -
Django Boostrap TimePicker/Forms not working

Django no User with same username in database
I'm particularly new to django and still in the learning process. I have this code where it would have the user input any text into the field and once the user hits the submit button it would grab the text they inputted and look for it in the django database for that item. It's able to do what I want, except when there are no users with that username. I don't know where I would do an if statement, or a work around for that. views.py from .forms import RequestPasswordResetForm from django.contrib.auth.models import User def request_password(request): next = request.POST.get('next', '/') if request.method == "POST": user = request.POST['passUsername'] users = User.objects.get(username=user) form = RequestPasswordResetForm(request.POST) if form.is_valid(): form.save() messages.success(request, 'Request has been sent!

Populate HTML table (dataTables) with AJAX+JS data in Django
I have an HTML page on Django which currently has two tables. The first table contains certain data related to a unique id key. Once the user clicks on an "Edit" button, Django populates a form using the available data using the id key. However, I also want to populate a second table ( different from the first one in the DB) by only showing the records related to the id under edition, passing it using a view. If no record is intended to edit, the table must appear empty to the user. I'm able to load the records from both tables using ajax: $(document).ready(function() { var 1Table= $('#FirstTable').DataTable( { "ajax": {"type":"GET", "url" :"/Deal/request_first/, "data":function( e ) { e.placeholder = "asdf"; } }, "columns": [ { "className": 'edit-control', "width": "12px", "defaultContent": '<button type="button" class="btn-primary"></button>' }, { "data": "id" }, { "data": "A" }, { "data": "B" }, ], } ); var 2Table = $('#Secodntable').DataTable( { "ajax": {"type":"GET", "url" :"/Deal/request_second/", "data":function( d ) { d.placeholder = "asdf"; } }, "columns": [ { "data": "id" }, { "data": "C" }, { "data": "D" }, ], } ); If the 'edit-control' is clicked, I'm calling a view that passes the data from the … -

Dictionary output with Django
I need to create a dictionary with the ID's of my users, and also with the coordinates of geocoding API from Google! (The ID is not relevant for the API, but it is for me so i can connect each location with it's own data) This is a template of the dictionary i need to pass to my js script: var markersOnMap = [ { id: { id: 1 }, LatLng: [{ lat: 19.392856, lng: -99.162641 }] }, { id: { id: 2 }, LatLng: [{ lat: 19.393686, lng: -99.170752 }] }, ] This is the views.py script: I'm getting all the addresses and ID's from my users. The API processes the address and returns 2 coordinates: lat and lng, is there a way or a better way to return to the js script each block of data containing the id with it's coordinates and so on per user as i mentioned above? def test(request): # ADDRESSES AND ID'S FROM ALL USERS data = list(UserProfile.objects.values('address', 'id')) # GOOGLE API API_KEY = 'MyApiKey' params = { 'key': API_KEY, 'address': data } base_url = "https://maps.googleapis.com/maps/api/geocode/json?" response = requests.get(base_url, params=params).json() response.keys() if response['status'] == 'OK': geometry = response['results'][0]['geometry'] lat = geometry['location']['lat'] lng = … -
Django inner join with search terms for tables across many-to-many relationships
I have a dynamic hierarchical advanced search interface I created. Basically, it allows you to search terms, from about 6 or 7 tables that are all linked together, that can be and'ed or or'ed together in any combination. The search entries in the form are all compiled into a Q expression. I discovered a problem today. If I provide terms for sub-tables that are (somewhere along the line of foreign keys) in a many to many relationship, the output table will include results from that table that don't match the term. My problem can by reproduced in the shell with a simple query: qs = PeakGroup.objects.filter(msrun__sample__animal__studies__id__exact=3) sqs = qs[0].msrun.sample.animal.studies.all() sqs.count() #result: 2 The ids in sqs include 1 & 3 even though I only searched on 3. I'm hoping I won't have to completely rewrite my interface to do the type of join that only retrieves a record and links to study id 3. Is there a way to do such an inner join as the result of a single Q expression in a filter on the entire set of linked takes that whose fields are in the resulting html table in the template? I'm betting it's not possible without … -

Create and get the id of a model's attribute in Django
Im working in a project where users can register their shops addresses in a Django model and i can display all those addresses in a google map. For that i need the addresses but also a way to access to that specific user's shop info, how can i create an id linked or pointing to the user's "address" attribute in my extended users models, and how do i call all those ids? models.py class UserProfile(models.Model): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE, related_name='user_profile') address = models.CharField(null=True, blank=True, max_length=150) views.py def test(request): addresses = list(UserProfile.objects.values_list('address')) address_id = ???????? context = { 'address_id': address_id, 'addresses': addresses } return render(request, "test.html", context) -
Create a preview screen in Django
I have a Django form that receives a text (that I copy from Google Classroom: a bunch of student comments). I use these comments to make student's attendance. What I want to achieve is: Accessing /insertion/ url via GET user receive the page form as a response, to choose the class (class01, class02, etc) and to past the text When the user clicks on submit in this form (post method), it is redirect to the same /insertion/ url, but now the form is bound to the data submited, and the page shows a preview page (based on a boolean variable I'm passing through context), showing what students are present and what are absent based on the text informed. At that page, a new submit button will be shown below a text like "if everything's ok, hit the ok button". After click this ok button, a pdf will be generated and the user will be redirected to /files/ url, to see the generated pdf and previous generated pdf. views.py def insertion(request): context = {} if request.method == 'GET': form = AttendanceDataForm() context.update({"form": form}) if request.method == 'POST': form = AttendanceDataForm(request.POST) context.update({"form": form}) if form.is_valid(): lesson = form.cleaned_data['lesson'] raw_text = form.cleaned_data['raw_text'] # … -
Trouble creating unit tests for Django admin action
I am having a bit of trouble figuring out where to mock and patch things and it's not making sense to me. I'm creating an admin action that fetches a token from a third-party API, and then instantiates an instance of a local class (that connects to said API) and makes API calls based on the item id. For example, let's assume that I'm storing restaurant ratings in an external location, accessible via API calls, and I'm storing users locally. I want to create an admin action that goes through each selected user and deletes all restaurant ratings in my external location, which is authenticated via a fetched token. I know this is not an optimal way to do things, but this is obviously not a real example, just an analogue of something a bit more complicated. Here is the structure of my project. from external_class_location import ReviewClass # This is the class that hooks into the restaurant review location from external_function_location import get_token # This is the method that fetches the token from that external location class UserAdmin(admin.ModelAdmin) actions = ['delete_reviews', ] def delete_reviews(self, request, queryset): reviews = ReviewClass(get_token()) for user in queryset: reviews.delete_all_reviews(user) delete_reviews.short_description = "Delete all reviews …
