Redirect to model creation if it doesn't exit
When I login to django as a superuser, if an object of some model or the a field of the last object in that model doesn't exist or isn't set, how would I redirect to the creation of that model? And don't let me access the WebApp unless it's made? I'm guessing there's a function to be run whenever a superuser logs in and check for an object or a field in the last object. I just don't know how to make this function and where to put it. Thank you for your time reading this. -
Use of Django and GeoDjango simultaneously
I've a doubt about the use of GeoDjango with Django. I've two app in my project: Blog and Map. This two app are in relation with a third app Kernel. Inside Kernel there are some models useful for Blog and Map and one of they is the TimeManager. TimeManeger is a simple model that "manege the time": from django.db import models class TimeManager(models.Model): publishing_date = models.DateTimeField( 'Published at', default=timezone.now, ) updating_date = models.DateTimeField( 'Updated at', auto_now=True, ) timestamp = models.DateTimeField( auto_now=False, auto_now_add=True, ) class Meta: abstract = True Into Blog there is a model Post: from django.db import models from kernel.models import TimeManager class Post(TimeManager): title= slug= descrtiption= . . Into Map there is a model MyMap: from django.contrib.gis.db import models from kernel.models import TimeManager class MyMap(TimeManager): geom = models.PointField() title = . . Now, my doubt is this: is correct to use TimeManager both for geometric models and not geometric models? I know that GeoDjango inherit from Django his models but I don't know if my approach is correct. -
How do I properly link my JSON credentials file in Django settings.py?
I am using the Django-gcloud-storage library to allow my Django app to store images on GCS. I already created a bucket, GCS service account and downloaded a JSON keyfile according to the tutorial. However, saving an image to the Cloud storage raises this error: AssertionError at /showroom/create/ Credentials file not found ... /srv/showroom/views.py in form_valid images.save() … ▶ Local vars (showroom/create is the upload form). This is how I have linked to it in my settings.py GCS_PROJECT = "torque-xxx" GCS_BUCKET = "torque-xxx.appspot.com" GCS_CREDENTIALS_FILE_PATH = os.path.join(BASE_DIR, 'static', 'js', 'torque-xxx-02827c7cc0ad.json') # GCS_CREDENTIALS_FILE_PATH = '/static/js/torque-256805-02827c7cc0ad.json' ## This was my first try, didn't work # DEFAULT_FILE_STORAGE = 'google.storage.googleCloud.GoogleCloudStorage' DEFAULT_FILE_STORAGE = 'django_gcloud_storage.DjangoGCloudStorage' I'm very unfamiliar with Cloud storage and APIs, so forgive me if this is a novice question. :-) -
How can I execute a Python script in Django views with pk
I'm writing web application - product generator based on Django Forms. One of the functionality is creating a bill of materials for production according to options user pick up. I have python back-end script in two versions: functions and classes. They are running perfect but I can't handle how to execute them in Django Views. I prefere to keep business logic in usecases and import them to views. I've red a lot about it and as a newbie, still can't solve the problem. Should I use simple View, FormView, TemplateView, CreateView? # urls from django.urls import include, path from . import views urlpatterns = [ path('<int:pk>/detail/bom/', views.BillofMaterialsFormView.as_view(template_name='bom.html'), name='conveyorform_bom'), # html <form action="#" method="get"> <button name="bom" value="Submit">Get Bill of Materials</button> </form> # views from django.shortcuts import render from django.views.generic import ListView, CreateView, UpdateView, DetailView, FormView from django.urls import reverse_lazy from .models import Conveyorform, ConveyorType, ConveyorModel from .forms import ConveyorformForm from conveyorform.usecases.bill_of_materials_creation import BillOfMaterials class BillofMaterialsFormView(FormView): template_name = 'bom.html' model = Conveyorform form_class = ConveyorformForm success_url = reverse_lazy('conveyorform_bom') def post(self, request, *args, **kwargs): form = self.get_form() if form.is_valid(): self.run_use_case(form) if not form.errors: return self.form_valid(form) return self.form_invalid(form) def run_use_case(self, form): usecase = BillOfMaterials( conveyorform_id=form.data['id'] ) usecase.get_conveyormodel_name() usecase.get_components_by_conveyormodel_name() usecase.create_components_table_for_instance() usecase.create_bill_of_materials_per_conveyorform_instance() Python script as classes … -
How to extend the locking/transaction between the views?
I have the functionality where I want to extend the transaction between two views. When a user clicks on 'Place Order' then the transaction begins and user is redirected to the merchant site to process the payment. In that case, where the control is not in the view where the transaction was written then How do I keep the locking alive unless the user returns on either of the defined callback URLs and then release it. (And, another story is when user don't even land on callback then is there a quick option to auto-release the lock if the transaction isn't completed in set time boundaries) -

I am getting Template Does Not Exist at / when I'm running my server in Django
When I run server I get Template Does Not Exist at / for my index.html page. Same problem occurs for other templates as well.

MySQL | Django | subclasses of BaseDatabaseOperations may require a datetime_cast_date_sql() method
I am using MySQL as database in Django Application.

How can I nest Django template language?

Concurrency Payment System
When I click on 'Place Order' I have begun the transaction and set the column is_payment_processing to True before taking the user to the merchant website and then there could be three possibilities: User landed on success callback page User landed on failure callback page User landed neither on success nor on failure callback coz he closed the window. The product will remain in the state where is_payment_processing is True. And, other users who attempt to check out the same product will not be able to do so. Thinking to have a cron job to run every minute which will track the last modification time of that column and if it is not been altered for more than 3 minutes then set that flag to False. What should be the best approach here? How in general scenario this is implemented? (Concurrency Control) -
Django/plotly.js: Pass Pandas Dataframe columns to template chart
I have a pandas dataframe (not user input) stored in my database as a csv. I extract this csv in my view, and then want to pass two columns to my template and into a plotly.js chart: a date column and a value column. How should I correctly pass these as template variables in order for plotly javascript to interpret them correctly? attempted solution: views.py def chart_function(request): df = #dataframe is extracted from DB using some code dates = df['dates'] values = df['values'] return render(request, template.html, {'values': values, 'dates': dates}) template.html: <div id="myDiv"></div> <input type = "hidden" id = "dates" name = "variable" value = "{{dates|safe}}"> <input type = "hidden" id = "values" name = "variable" value = "{{values|safe}}"> <script type = "text/javascript"> var dates = document.getElementById("dates").value.split(','); var values = document.getElementById("values").value.split(','); var trace1 = { x: dates, y: values, type: 'scatter', }; var data = [trace1]; Plotly.newPlot('myDiv', data, {}, {showSendToCloud: true}); </script> The plot actually plots somewhat correctly, but it's clear that the dates are not being passed as date objects because the x axis has dates within strings and brackets. I need the df columns to be recognized as dates/values by plotly javascript. I think my halfway solution is … -

Django AttributeError: type object 'Book' has no attribute '_default_manager'
I created a simple Django Webapp using django-neomodel integration. When trying to create a new book, at "http://localhost:8000/book/new" and after submitting it, I see the error as shown in the traceback. I have searched online, and in most of the cases, the errors seem to be because of some typos in specifying the model name, or inadvertently usage of strings. I have double-checked for such reasons, but couldn't see any such issues in my code. Also, I tried using Forms, by creating a form and giving a specifying form in the views, rather than model itself. But I see the same error in that case too. models.py: TITLE_MAX_LEN = 100 USERNAME_MAX_LEN = 25 NAME_MAX_LEN = 25 class Book(DjangoNode): custom_pk = UniqueIdProperty() title = StringProperty(max_length=TITLE_MAX_LEN, unique_index=True, required=True) description = StringProperty() difficulty = IntegerProperty() importance = FloatProperty() class Meta: app_label = 'knowledge' def __str__(self): return self.title def get_absolute_url(self): return reverse('book-detail', kwargs={'pk': self.custom_pk}) views.py class BookCreateView(CreateView): model = Book fields = ['title', 'description'] template_name = "knowledge/book_form.html" class BookDetailView(DetailView): model = Book template_name = "knowledge/book_detail.html" urls.py urlpatterns = [ path('book/new/', BookCreateView.as_view(), name='book-create'), path('book/<str:pk>/', BookDetailView.as_view(), name='book-detail'), ] Traceback: Traceback: File "/Users/sam/code/website/django_env/lib/python3.7/site-packages/django/core/handlers/exception.py" in inner 34. response = get_response(request) File "/Users/sam/code/website/django_env/lib/python3.7/site-packages/django/core/handlers/base.py" in _get_response 115. response = self.process_exception_by_middleware(e, … -
Django Secret Key Compromised
I am wondering what are the steps one would need to take should the production secret key become compromised. Luckily, that is not the case, but it would be good to know, nonetheless. In particular, what happens if one simply swaps the old key to a newly generated one? Since it is used in making hashes, does it break the entire system or make it unstable? In the case of a compromise, would the response be as simple as generating a new key and inserting it into the production settings? -

Python/Django How do I make it so that only the creator of an object/post can see a delete/edit function button for their post?
I am currently new to python developing and am currently in school to learn multiple stacks. My code is in the most basic form. I haven't gotten to authenticated yet nor have i ever been introduced to KWARGS or pk. I also don't even know what those are at this moment. How would I make it so that the delete button only shows up to the side of the "Thought" post of the User who created the object so that they can delete it themselves but the button wouldn't be available for other User's posts? Also, how would I implement a single Like/Dislike button that transitions back and forth for every Object post in the most simple form of what I have learned thus far? this is my current code. models.py from __future__ import unicode_literals from django.db import models import re import bcrypt class UserManager(models.Manager): def registration_validator(self, postData): errors = {} EMAIL_REGEX = re.compile(r'^[a-zA-Z0-9.+_-]+@[a-zA-Z0-9._-]+\.[a-zA-Z]+$') if not EMAIL_REGEX.match(postData['email']): # test whether a field matches the pattern errors['email'] = ("Invalid email address!") if len(self.filter(email = postData['email'])) > 0: errors['email'] = "Email address has already been taken!" if len(postData['first_name']) < 2: errors["first_name"] = "Insufficient amount of character letters, you must type over 2 … -
Appending own Django DB data to data from an REST API in Graphene
I'm currently trying to figure out how to work with GraphQL with Python (graphene-django). There's one thing which is not clear to me yet which is how to append own data to REST API data (or vice-versa). The REST API I'm using is made in NodeJS/Express and should not be meddled with to maintain compatibility with other software/clients. The GraphQL node will be used as an end-point to access that REST API, but also to persist own data to an own DB and later on to connect to other REST APIs. Anyhow, so I've found this article about how to build a GraphQL wrapper, but the code examples only show how to fetch complete objects and convey it to the client. Thus no appending. Sidenote: I'm just exploring options, choosing between Apollo Server(JavaScript) and Graphene+Django. The syntax of the code below could be incorrect. I'm just trying to get a grasp on the concept. An example of how the Model class would look like: # models.py from django.db import models class User(models.Model): # REST API data - fetched from a different server. id = models.IntegerField() name = models.CharField(max_length=100) email = models.CharField(max_length=320) avatar = models.CharField(max_length=64) # etc # Own DB data … -
Not able to see the filter option with Django class based views
