Django create view with parent model and child information
I am a beginner with Django and feel I have a fundamental misunderstanding of how to use context dictionaries. I am trying to make a function list view where it displays a list of parent models(projects) and under each project it displays the child models(stages).NOTE: I am creating a function list view rather than using a generic list view so I can include more logic such as booting those that aren't staff. I would like the list to look like: Project A Stage A(For Project A only) Stage B(For Project A only) Project B Stage B(For Project B only) My current code prints all stages in the database for each Project even if it is not the right one, but i also tried {% for stage in project.stages %} and got an error. Here are my models class Project(models.Model): name = models.CharField(max_length=70, null=False, blank=False) completion_date = models.DateTimeField(verbose_name="completion_date", null=True,blank=True ) class Stage(models.Model): DESIGN = "DESIGN" QUOTE = "QUOTE" DEPOSIT = "DEPOSIT" SCREENSHARE = "SCREENSHARE" DIGITAL_PROOF = "DIGITAL_PROOF" SAMPLE_PRODUCTION = "SAMPLE_PRODUCTION" WHOLESALE_PRODUCTION = "WHOLESALE_PRODUCTION" SHIPPING = "SHIPPING" STAGE_TYPE_CHOICES=[ (DESIGN,'Design'), (QUOTE,'Quote'), (DEPOSIT,'Deposit'), (SCREENSHARE,'Screenshare'), (DIGITAL_PROOF,"Digital Proof"), (SAMPLE_PRODUCTION,"Sample Production"), (WHOLESALE_PRODUCTION,"Wholesale Production"), (SHIPPING,"Shipping") ] project=models.ForeignKey(Project, related_name="stages", on_delete=models.CASCADE) type = models.CharField(max_length=30, choices=STAGE_TYPE_CHOICES,) completion_date = models.DateTimeField(verbose_name="completion_date", null=True,blank=True ) … -

403 Forbidden Error When Editing a Form - Javascript and Django
I'm trying to use a form to edit a previous post on my site. After clicking edit, using Javascript, I'd like this to happen without requiring a reload of the page. I'm using Django and trying to use fetch in the Javascript file but I'm pretty lost as to why it's not working. I've been having a lot of trouble with saving things to the database, but also using Javascript at the same time. Any help is appreciated. When I click edit and try to save, I get 403 forbidden error. relevant urls.py - I tried this with edit_post/ and it still didn't work: path('edit_post', views.edit_post), javascript: edit = document.querySelectorAll(".edit"); edit.forEach((element) => { element.addEventListener("click", () => { edit_handeler(element); }); }); function edit_post(id, text) { form = new FormData(); form.append("id", id); form.append("text", text.trim()); fetch("edit_post", { method: "POST", body: form, }).then((res) => { document.querySelector(`#post-content-${id}`).textContent = text; document.querySelector(`#post-content-${id}`).style.display = "block"; document.querySelector(`#post-edit-${id}`).style.display = "none"; document.querySelector(`#post-edit-${id}`).value = text.trim(); }); } function edit_handeler(element) { id = element.getAttribute("data-id"); edit_btn = document.querySelector(`#edit-btn-${id}`); if (edit_btn.textContent == "Edit") { document.querySelector(`#post-content-${id}`).style.display = "none"; document.querySelector(`#post-edit-${id}`).style.display = "block"; edit_btn.textContent = "Save"; edit_btn.setAttribute("class", "text-success edit"); } else if (edit_btn.textContent == "Save") { edit_post(id, document.querySelector(`#post-edit-${id}`).value); //here edit_btn.textContent = "Edit"; edit_btn.setAttribute("class", "text-primary edit"); } } views.py … -

GCP: connect to Memotystore from cloud run Django app?
I'd like to add cache to my Django app hosting on Cloud Run. From Django official docs, we can connect Django to a memory-based cache. Since I'm using Cloud Run, the memory get cleaned.

How to rename file in django which uses custom storage?
I am using a custom django storage class (digitalocean spaces), which behind the hood uses S3. I have some code which uses "os.rename". Django provides a utility called default_storage through which we can use some of os module's features in remote storage. However, it doesn't have the ability to rename/move/copy a file. I am doing a lot of file operations in the backend using os module. However, in production, the file storage system would be digitalocean spaces. Which means I can't do file operations using os module, I have to use django's default storage utility which doesn't provide all features of os module. Will my code still work in a remote storage or will it fail? If it will fail, then how can I solve it? -

Python Request inside Django View stop request when client gets disconnected
I have an DRF API in which a client will call then once called it will pass the data from client to another server (using request package) and returns to client the response of the other server. In short, I am an API in the middle to sync them. Now, I need to terminate the request to other server (the one that is using request package) from my DRF API once the client got disconnected to my DRF API. Note. I need to terminate it because the data sending from the client is need to be map by the id being returned from the other server, and the client needs to save the id they received. In case your wondering why my API exist, the client can just sent the request over to the other server directly. Because the other server is a legacy server and it runs SOAP so my API is converting the JSON payloads to SOAP payload then from SOAP payload to JSON payload. -

Django log errors and traceback in file in production environment
I'm quite new working with logging in django, I'm making a production deployment (DEBUG=False) of an app but I'm not allowed to use any error tracker like Sentry to catch possible problems, so I was wondering if it's possible to log the traceback or part of it in production environment to a file using a logger.
