What common approaches do I have to scaling data imports into a DB where the table structure is defined by Django ORM?
In the current project I'm working on we have a monolith Django webapp consisting of multiple Django "apps", each with many models and DjangoORM defining the table layout for a single instance Postgres database (RDS). On a semi-regular basis we need to do some large imports, hundreds of thousands of rows of inserts and updates, into the DB which we use the DjangoORM models in Jupyter because of ease of use. Django models make code simple and we have a lot of complex table relationships and celery tasks that are driven by write events. These imports have grown, and cause performance degradation or can be rate limited and take weeks, by which time data is worth a lot less - I've optimized pre-fetching and queries as much as possible, and testing is fairly tight around this. At other places I've worked, there's been a separate store that all ETL stuff gets transformed into and then some reconciliation process which is either streaming or at a quiet hour. I don't understand how to achieve this cleanly when Django is in control of table structures. How do I achieve a scenario where: Importing data triggers all the actions that a normal DjangoORM … -
Django Stripe Attribute Error - module 'requests' has no attribute 'Session'
I'm trying to get a basic Stripe set up in Django project but cannot get past this error. I am able to submit the initial Stripe form (get the green check) but I can't complete the payment and get successful payment template to show. I used an online tutorial that got me this far. Have been trying to use the Stripe docs and looking everywhere I can think of online but can't get anything to work. If someone help me with how to define a 'Session' that would be really appreciated.

URL error in {% url ... %} when breaking line in source code
I'm working on an app in Django (2.2) and I've run into an issue with one of my html templates, where the URL doesn't work when the source code line breaks inside a {% url ... %} tag. This is the code that doesn't work: <small><a href="{% url 'learning_logs:edit_entry' entry.id %}">edit entry</a></small> This is the error I get: Page not found (404) Request Method: GET Request URL: http://localhost:8000/topics/2/%7B%25%20url%20'learning_logs:edit_entry'%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20entry.id%20%25%7D Using the URLconf defined in learning_log.urls, Django tried these URL patterns, in this order: admin/ users/ [name='index'] topics/ [name='topics'] topics/<int:topic_id>/ [name='topic'] new_topic/ [name='new_topic'] new_entry/<int:topic_id>/ [name='new_entry'] edit_entry/<int:entry_id>/ [name='edit_entry'] The current path, topics/2/{% url 'learning_logs:edit_entry' entry.id %}, didn't match any of these. This is the code that works: <small><a href="{% url 'learning_logs:edit_entry' entry.id %}"> edit entry</a></small> Does it mean you can't break the line in source code inside {% url ... %} tags?

Django template iterate over context list
I can't find a clear answer on this. I have a view that shows multiple models. In my template, I have written out everything to manually display what I want but it doesn't really stick to DRY so I'd like to iterate over the context. What I can't find is what the context object is referenced as in my template? I have written pseudo code in the template snippet below of what I want to achieve. views.py class ConfigurationDetailView(LoginRequiredMixin, TemplateView): ''' Returns a view of all the models in a configuration ''' template_name = 'configurator/configuration_detail.html' def get_context_data(self, **kwargs): ''' Uses a list of dictionaries containing plural strings and models to filter by the configuration ID to only show items in the config.

How to return multiple values in Django Select2 autocomplete form
I am using Select2 for django to create autocomplete form. I would like for autocomplete form to return more fields from database. For example: in models i have this: class Places(models.Model): r_name = models.CharField(max_length=200, default=None) r_country = models.CharField(max_length=20, default='Englands', blank=True, null=True) r_place = models.CharField(max_length=200, default=None, blank=True, null=True) I want form to return r_name + r_country + r_place. When i was using jquery autocomplete, i wrote it like that and it worked: def PlacesNameAutocomplete(request): if request.is_ajax(): q = request.GET.get('term', '').capitalize() search_qs = Places.objects.filter(r_name__startswith=q) results = [] print(q) for r in search_qs: results.append(r.r_name + ' (' + r.r_country + ' - ' + r.r_place + ')') data = json.dumps(results) else: data = 'fail' mimetype = 'application/json' return HttpResponse(data, mimetype) Right now i am using this Select2 code for autocomplete, form returns r_name, but I don't know how to add country and place to return results. Views.py from dal import autocomplete from places.models import Places class PlaceAutocomplete(autocomplete.Select2QuerySetView): def get_queryset(self): queryset = Places.objects.all() if self.q: queryset = queryset.filter(r_name__istartswith=self.q) return queryset Forms.py class newActivityForm(ModelForm): route_id = forms.ModelChoiceField( queryset=Places.objects.all(), widget=autocomplete.ModelSelect2(url='place-autocomplete', attrs={'data-placeholder': 'Start typing name ...', 'data-minimum-input-length': 3, 'style': 'width: 100%' },)) -
Django Crispy Forms / Adding my own classes
I want to change the design of crispy form field with my own classes. I read some information about it but could no find the solution. Let me add my files and explain: forms.py from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User from django import forms from django.core.exceptions import ValidationError class UserRegisterForm(UserCreationForm): ...some code... email = forms.EmailField(label='İTÜ Maili') class Meta: model = User fields = [...'email'] widgets = { 'email': forms.EmailInput(attrs={'class': 'myClassName'}), } This is how I wanted to add my class to email field. register.html <div class="container-fluid mt-5"> <div class="row justify-content-center text-center"> <div class="col-4"> </div> <div class="col-4"> <form class="mt-5" id="registerForm" method="post"> {%csrf_token%} {{ form.email|as_crispy_field }} <button type="submit" value="SIGN UP" class="button is-secondary">Submit</button> </form> </div> <div class="col-4"> </div> </div> </div> This is my template. I added background-color:black; to my css class to check whether it works, but unfortunately it did not work. I tried to write the template with labels and inputs but messed up with validation errors and etc. Is there any way doing this only using crispy form code like I have written: ({{ form.email|as_crispy_field }}) -
Using Jinja2 MemcachedBytecodeCache With Django
I apologize if this answer is obvious, but I can't seem to figure out how to enable Jinja2's MemcachedBytecodeCache in Django (I'm using version 3.0, but generally either). Jinja's documentation makes it sound like it a relatively straightforward setting: class jinja2.MemcachedBytecodeCache(client, prefix='jinja2/bytecode/', timeout=None, ignore_memcache_errors=True) This class implements a bytecode cache that uses a memcache cache for storing the information. It does not enforce a specific memcache library (tummy’s memcache or cmemcache) but will accept any class that provides the minimal interface required. The goal, obviously, is to enable Jinja's bytecode caching with Memcached, which is already enabled on my site. Any assistance in implementing this in settings would be much appreciated. Thank you! -
How can I create multiple objects with one view/form in Django
So here's what I'm attempting to do, and if there's a better way, please let me know. I am creating a dating app and am attempting to create a message form that displays once a user has matched with another user. I already have the matching down and the users displaying correctly, but I need this messaging component. This will be in the form of a link beneath the user's profile that my user has matched with. Now, my InstantMessage model has a foreign key to Conversation which should contain 2 members, whom are having a conversation and contains at least one message exchanged between each other . Now, I what I want to do, when a user hits a link to start messaging, to have my code check if there is already a conversation object between the two users, and if so, then use that conversation object pk for my conversation field in Instant Message and then create a form for that. And if there isn't, then I want a conversation object to be created first, and then a message object to be created. I want this all in one view and with one link, so I assume I … -
Django Python: can't open file 'manage.py': [Errno 2] No such file or directory
I'm having the same issue as this question regarding deploying a Django project to Heroku. I've followed the comments to investigate further, but there's no additional feedback from the original poster to finish the conversation. Following on the Mozilla instructions I make it to the heroku run python manage.py step, which returns the error below: Running python manage.py migrate on ⬢ fast-oasis-14644... up, run.2316 (Free) python: can't open file 'manage.py': [Errno 2] No such file or directory Following the comment from Chris in the referenced question, I ran heroku run bash to get a shell on a one-off dyno. Looking at the structure there, the manage.py file is two levels down in the clmp folder, which is the name of my Django app. ~ $ ls Procfile README.md requirements.txt runtime.txt src ~ $ cd src ~/src $ cd clmp ~/src/clmp $ ls assets clmp contracts manage.py templates I'm assuming that this means something is misaligned with what Heroku is looking for vs my Procfile setup, but I've used web: gunicorn clmp.wsgi --log-file - following on the Mozilla instructions referenced above. My git push to Heroku master is successful. Thanks in advance for the help. -
Counting number of records in database: Django
I'm trying to output the count of the number of "subscribers" in my database in Django, I've found count in my view and then I think I'm using it correctly in the html, but it always just outputs "there are subscribers" without the number, when I use "|length" in the html it always outputs 0, so I'm not sure what my error is. views.py def list_todo_items(request): context = {'todo_list' : Todo.objects.all()} count = Todo.objects.count() context2 = {'count': count} # context = {'count': Todo.objects.count()} # count = Todo.objects.count() return render(request, 'index.html',context,context2) def insert_todo_item(request: HttpRequest): todo = Todo(content=request.POST['content']) try: todo.full_clean() except ValidationError: # pymsgbox.alert('ValidationError!

Plotting map with python
I am trying to get a map to plot coordinates which i have saved in my csv file using python and have output it to my django site.

Django prevent data from passing in URL
I am new to Django and web dev. I am currently working on a textbox that a user will input data. Then they will click submit and I want that data to go to another page. However when they click the submit button, all the text ends up in the URL. The amount of text that will be passed in this text area is going to be thousands of characters. Is it possible to not allow it to appear in the url? This is my textbox and submit button: <form action="{% url 'parsed' %}"> <textarea name="fulltextarea" cols=40 rows=10></textarea> <br /> <input type="submit" value="Submit"/> </form> urls.py urlpatterns = [ path('', views.home, name='jsonparser-home'), path('parsed/', views.parsed, name="parsed") ] views.py def parsed(request): data = request.GET.get('fulltextarea') print(data) return render(request, 'jsonparser/parsed.html', {"json":data}) Now when I enter text into my text box and click the submit button my URL gets the data in it as: http://localhost:8000/parsed/?fulltextarea=wefwefallmydatasubmittedishere Is it possible to remove all of that in the URL? -
How to post a list of objects containing file input with Axios post and Django
I want to create a web app that allows users to upload a list of files with an associated file name that the user chooses. I want my POST to look as below. {"user": "ME", "files": [{"file":"InMemoryFileUpload", "name": "file_name"}, {"file":"InMemoryFileUpload", "name": "file_name1"}]} I cannot find a way of extracting the files from the POST for this particular use case. I can extract the elements from the list if there are no file objects, and I can extract files if they are not stored in a list. Here is my simplified React script import React, { Component } from "react"; import axios from "axios"; class SomeForm extends Component { handleSubmit(e) { e.preventDefault(); const user = '3' const selectedFile = e.target.input.files[0]; const selectedKey = e.target.keyName.value var formData = new FormData(); formData.append('user', user) formData.append('files', [{'name': selectedKey, 'file': selectedFile}, {'name': 'TEST', 'file': selectedFile}]) axios.post("http://localhost:8000/api/handle_user_input/", formData) } render(){ return( <form onSubmit={this.handleSubmit}> <label>Upload File:</label> <input type="text" name="keyName" /> <input type="file" name="input" /> <button type="submit">Upload</button> </form> ); } } export default SomeForm; The request POST.data is like below <QueryDict: {'user': ['3'], 'files': ['[object Object],[object Object]']}> How can I POST the files correctly in this format?

How to resize images with Django when uploading to AWS S3?

Aborting long running request in Django
I want to abort a request to an API which takes longer than 5 seconds. I know the client-side code can have a timeout of 5 seconds and that will ensure it doesn't wait any longer than that to get a response, but the Django server would still be processing the request even though the client won't be receiving it at the end. As far as I know, even if I configure this on nginx or gunicorn, those will still act as clients for the Django server app and the same problem will occur - that nginx will not wait for more than 5 seconds, but Django will continue processing the request. Is there any way I can somehow abort this request processing in Django (application server code level) itself? -

Safest and driest way to filter query_set depending on some user info
I have a Post model with a boolean field, is_draft. If the user is logged and is member of the staff, then I want to displays all posts; otherwise, only the posts for which is_draft is false. My first thought was to use a custom model manager and use request.user as following: class PostManager(models.Manager): def get_queryset(self): if request.user and request.user.is_staff: return super().get_queryset() else: return super().get_queryset().filter(is_draft=False) but request is not available in the model. I saw some people use a middleware to access the user in the model. It seems to me the safest way to address my need (ie it's done once, in the custom manager; people modifying the views.py don't have to bother, no risk of forgetting it) but this solution seems controversial. I have of course the possibility to add some logic in the view, but I feel this is not DRY (as I query Post many times) nor safe (risk somebody forgets it at some point). According to you, what would be the cleanest and safest way to address this need? PS: I've found a similar question for which a solution was proposed for Class-based views, but my views are function-based. Thanks a lot! -
How to change href in django based on the current page url?
As I said in the title, what would be the correct syntax to change the href of a link according to the current url the user is on? I tried this, but it doesn't work. {% if url == '' %} href='/cookies' {% else %} href='' {% endif %} What would be the correct syntax to do this? -
