Cannot pass variables between javascript function and ajax in django project
This is a proper noob question it would seem, so apologies, but I can't seem to solve it so I'm reaching out for some assistance. I have a function in my .js file that interacts with the Google Places library to autocomplete a field in a form. I then have an ajax function that runs when you click the submit button which creates variables in the django session. The data of interest to me is lat and long. However, for some reason, I can't seem to get the data to pass from one to the other. I know the ajax function is working because if I type in fixed values they propagate through to django, but I can't seem to get it to update dynamically. const csrf = document.getElementsByName('csrfmiddlewaretoken'); var lat; var lng; function autocomplete_location() { let defaultBounds = new google.maps.LatLngBounds( new google.maps.LatLng(49.6331, -11.7247), new google.maps.LatLng(59.4850, 1.5906)); let input = document.getElementById('id_your_location'); let options = { bounds: defaultBounds, types: ["address"], fields: ["name", "geometry"], }; let autocomplete = new google.maps.places.Autocomplete(input, options); autocomplete.addListener('place_changed', function() { // Get place info let place = autocomplete.getPlace(); // Do whatever with the value! lat = place.geometry.location.lat() lng = place.geometry.location.lng() console.log(lat) console.log(lng) }) } $(document).ready(function (){ $(".btn").click(function (){ … -
Django q update an already scheduled task
I am using Django-q to schedule a task at a specified date in an object (lets call this bell). I am successfully able to do so using schedule_obj = schedule(func_name, arg1, arg2, arg3, schedule_type=Schedule.ONCE, next_run=bell.date) when there is an update to the obj bell that holds the date, I want to modify this schedule obj with the updated date (bell.date). Is there a way to check if there is a schedule pending for this specific func_name with the args and then access it to modify it? -

Why is my loop terminating before all items are looped through?
So I'm using Django and trying to dynamically add a users gists to the page using githubs embedded gists. this is the loop {% for i in snippets %} <div class="tile is-4"> <div style="height:25vh;"><script src="https://gist.github.com/{{i.owner.login}}/{{i.id}}.js"/></div> </div> {% endfor %} the list im looping through contains two items, however only the first is added. if I do something along these lines however it correctly displays the two different id's {% for i in snippets %} {{i.id}} {% endfor %} I read that the github script calls document.write(), I have a gut feeling this is where my issue lies. would document.write() break my loop? -

Passing varibles from API to template in Django
I am working on building a flight price search website as part of a project and have managed to get most of the functionality I require working. Here's what the front-end looks like so far: When users enter in the details, a POST request is sent to an API. API: https://developers.amadeus.com/self-service/category/air/api-doc/flight-offers-search API Python SDK: https://github.com/amadeus4dev/amadeus-python I'm receiving a response from the API; however, am struggling to understand what I should then do with the information received. The next step is to pass the information from the API into a search results template and split out all of the received flight information, similar to how it is displayed on Sky Scanner: Below is what I have in my views.py so far (currently passing in the whole response, in what I believe is JSON format?) Views.py: def flight_search(request): kwargs = {'originLocationCode': request.POST.get('Origincity'), 'destinationLocationCode': request.POST.get('Destinationcity'), 'departureDate': request.POST.get('Departuredate'), 'returnDate': request.POST.get('Returndate'), 'adults': '1'} try: response = amadeus.shopping.flight_offers_search.get( **kwargs) print(response.data) return render(request, "flightfinder/flight_search.html", { "response": response }) except ResponseError as error: raise error Here is an example response from the API: { "meta": { "count": 2 }, "data": [ { "type": "flight-offer", "id": "1", "source": "GDS", "instantTicketingRequired": false, "nonHomogeneous": false, "oneWay": false, "lastTicketingDate": "2020-11-20", "numberOfBookableSeats": 2, … -

How can I update the email address using the confirmation code in Django?
I use all the functionalities of dj-rest-auth to register, log in, confirm the email address, change the password, reset the password and many more. Unfortunately, the library does not support changing the email address. I would like the authenticated user to first enter the account password and the new email address. After the successful process of authentication, I would like to send the user a specially generated confirmation code. Only when he enters it, the old email address will be changed to the new one. As far as I know, there is no such functionality in dj-rest-auth. Unfortunately, I also have not found any current solutions or libraries for this purpose anywhere. Has anyone had a similar problem and could share solution here? Thank you in advance. -
How to iterate through all foreign keys pointed at an object in Django without using _set notation?
I am fairly new to Django, but I am working on an application that will follow a CPQ flow or Configure, Price, Quote. The user should select the product they would like to configure as well as the options to go with it. Once selected, the program should query an external pricing database to calculate price. From there the program should output the pricing & text data onto a PDF quote. I was able to get the application working using the specific product inheriting from a base product class. The issue is now that I've created a second product child class, I cannot use a singular "related_name". I've omitted the lists associated with the drop down fields to help with readability, but I've posted my models.py file below. Is there a way I can iterate through Product objects that are pointing to a Quote object with a foreign key? A lot of answers I've found on SO relating to this were able to be solved either by specifying the "_set" or "related_name". I've seen other answers use the select_related() method, however, I can't seem to get the query right as the program won't know which set it needs to look … -
Web Client to Display and Read from SFTP Server in Django Admin
What am I trying to do? I want to allow the user to configure an SFTP server and select the folders that should be downloaded. Following is how I the admin form to look like: Allow the user to configure an SFTP server (host, port, user, pass) from the Django admin On the same page, provide a connect button, which when clicked would connect to the SFTP server using the configuration (Step 1) and open up the SFTP server (either as a modal popup or in a new browser tab/window) The user selects the folders that should be included for parsing and save the admin form. Step 1 is fairly straightforward. However, I am unable to figure out if there's a preexisting module that I use to accomplish step 2 and 3. Basically what I am looking for is a Web SFTP client that I can integrate into my Django admin. I am looking for some guidance in order to achieve this setup. -
Rendering MPTT structure with open/close possibility in django template
I need to render my MPTT model as tree with dropdown (open/close every node that contains children) possibility and buttons that will open/close all the nodes in that tree in 1 click.

Django login error when using incorrect username and password on AWS

Django Insert With UUID Foreign Keys Issue
I've been building a Django model using UUIDs as foreign keys. When I try to perform an insert the foreign key constraint kicks in stating that the key doesn't exist in the table, which is not true. If I take the query that is trying to be executed from the Django logs it runs fine in my SQL client. I'm using Django 3.1 with Postgresql 12.4 and trying to run the insert via mutation thru Graphene-Django. The model I'm inserting into is: class Inventory(models.Model): class Meta: db_table = "inventory" id = models.UUIDField(db_column='inventory_id', primary_key=True, default=uuid.uuid4()) item = models.CharField(db_column="inventory_item", null=False, max_length=750) quantity = models.FloatField(db_column="inventory_quantity", null=False) org_id = models.ForeignKey("org.Organization", db_column="organization_id", null=False, on_delete=models.CASCADE) unit_of_measure = models.ForeignKey("InventoryUnitOfMeasure", db_column="inventory_uom", null=False, on_delete=models.CASCADE) The query that Django is executing is: INSERT INTO "inventory" ("inventory_id", "inventory_item", "inventory_quantity", "organization_id", "inventory_uom") VALUES ('453b5dd5-1a9c-462f-adff-c93274e45cfe'::uuid, 'test string', 2000.0, 'f119b93a-d3e1-4f2a-8187-0d3f0ff8d148'::uuid, 'cec0c6e1-a0cc-4b38-b4d8-2c00367b9a01'::uuid); Running that query via SQL client works fine, but the error I receive is: insert or update on table "inventory" violates foreign key constraint "inventory_organization_id_7514cdb8_fk_organizat"\nDETAIL: Key (organization_id)=(f119b93a-d3e1-4f2a-8187-0d3f0ff8d148) is not present in table "organization" That key is in the organization table. If the query wasn't running in my SQL client I'd suspect that it's something around translating the UUID string value, but I'm out … -

Django Form - Why is the django Multiselect widget used in Admin page rendering in the same line as another field?
