Django + Javascript - How can we verify that the Django value is not null for execute Javascript?
With Django ORM and Javascript: How can we verify that the var1 value is not null? {% for station in stations0 %} var var1 = {{station.punto_comunicacion.latitud}}; if (var1 != None) { latlngs.push(new L.LatLng({{ station.latitud }},{{ station.longitud }})); latlngs.push(new L.LatLng({{ station.punto_comunicacion.latitud}},{{ station.punto_comunicacion.longitud}})); } {% endfor %} Thanks. -
Django: How to create an instance of a model without a form but by a button click
I am new to Django, so pardon me if my question is naive. I am trying to achieve a use case of text mining application on uploaded files, I am trying to show a "Get Started" button in the landing / home page. On button click I am rendering a file upload option. Now I am trying to treat this as a Scan Job, and wanting jobID to get created with the click of the button and the same jobID to be displayed further pages and this jobID to be used as primary key in other models. Below is the model I created. from django.db import models class sfs_job_model(models.Model): sfs_job_id = models.CharField(max_length=250,default="", editable=True) sfs_job_start_date_time = models.DateTimeField(auto_now_add=True, null=False) sfs_job_end_date_time = models.DateTimeField(auto_now_add=True,null=False) sfs_job_status = models.CharField(max_length=250, editable=False,empty_value=None,null=True) sfs_job_summary = models.CharField(max_length=1000) def save(self, *args, **kwargs): if self.job_id is None: self.job_id = 'SFS-' + str(self.id) return super(sfs_job_model, self).save(*args, **kwargs) Please guide me how to achieve the desired use case. Thanks in advance -

how to supply command line arguments to appconfig's ready from runserver django
I am working on a django project (consisting of a single app) and want to expose some configuration options for my app through CLI. Inside my cli.py file first I plan to accept these arguments and then use call_command to runserver from django.core.management.commands module. On the other hand in order to do some basic startup activities using the arguments accepted from cli, I have decided to use AppConfig's ready() function for the same. But I am unable to find some bridge using which the accepted cli arguments could be utilized during my application startup (inside ready()). Also the variables created using accepted arguments will be utilized inside my views. How should I design the flow to achieve the same ? -

Using form field and instance's initial arguments simultaneously instead of the __init__ method
I came across this django tutorial-like blog while trying to learn about django forms ( Link ) It says that using the initial argument in the form field only means that we cannot change the initial arguments for a particular instance of the class, and then starts explaining how to make use of the __init__ method for that exact purpose. A paragraph in the same article states that if we use the initial argument on both the form instance and form fields, form instance's initial values take precedence over any form field (e.g. if you combine the statements from listing 6-9 and listing 6-10, the form will always be pre-filled with email='johndoe@coffeehouse.com' and name='John Doe' from listing 6-9). Can't we just use initial arguments in the form field and then override it if we want to, while creating an instance of the class ? Why do we have to use the __init__ method for the same task? -
How can i structure my API - Django Rest Framework?
I'm redoing an old project of mine but I'm having trouble structuring it in my mind. What my app does : it creates custom reports for shops, based on multiple sources. Those sources are uploaded by the user in the form of multiple CSV files each row of those files linked to the shop id. Right now, what I do is: I upload all the files to my Django app, use a script to process them ( i use panda to clean my CSV files ), and create the report and then add that report to a DB. It works but I think is quite heavy ( there are 800+ shops and 5 CSV files sources + 3 API sources ) and I was wondering if there was a cleaner and simple solution. I'm thinking about using DRF, create a model for each source in a dedicated source app, parse each of the CSV files, and then add them to the DB a table per source. So when I need to create my reports, I'll just fetch the different metrics from the different sources and group them together. It is quite messy in my head, I guess what I'm asking … -

Django SuspiciousFileOperation: But Paths are correct
Fellow SOs: From one day to the other day, without making any changes other than installing windows updates, I get this error message: The joined path (C:\Users\X\Y\Z\data\static_files\admin\css\autocomplete.css) is located outside of the base path component (C:\Users\X\Y\Z\data\static_files\) I do know what the error means in general, but as the file is obviously within the base_dir, I dont get what is wrong. The error pops up on every page except for /admin. Settings: BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) MEDIA_ROOT = os.path.join(BASE_DIR, '../data/media_files/') STATIC_ROOT = os.path.join(BASE_DIR, '../data/static_files/') The setup still works fine on my Mac, but fails on Windows 10 since the last update.

Django SQLite working on Heroku production app
I read in lots of places that Heroku doesn't work with SQLite since it's a file DB. I've deployed a Django app to GitHub, including the sqlite db, and then created a Heroku app linked to that DB. When I do things like create a user/fill out forms on the heroku app, it saves the data as expected, and shows it on the page. In other words, it's being stored in the sqlite database since I have not added django-heroku or any postgres functionality myself. Howcome? What am I missing? Why does this work? -

Embedded youtube videos showing up blank in Django card-columns page
I'm working in a django project and i've run into an issue using embedded videos with bootstraps card-columns. We have a django plugin, Media Player, that simply puts a div & iframe on the page, most of the JS comes from the websites. The videos in question are from youtube, but i've tried vimeo videos and same result. The issue is that some videos work fine, but others don't show up on the page, they are blank/white. However, the video is still there, it takes up space & i can hover over it and see that the Media Player plugin is there. And I can hit the middle of it, where the play button should be and even though I won't see anything I can hear the audio from the video. It's also worth noting that when the page loads, for a brief second I can see the black box of the videos loading but they immediately go white. I can also use the inspect bow in the web browser to see the video exists on the page. I'm using boostrap with cards & the card-columns setup, column-count of 3 at XL, so 3 vertical rows of about 12 cards. … -

Django Update view creates new object while also updating
I'm working on a test application in Django and have run in to an issue I've been unable to solve. I have two models, Farm and Product which have a One to Many relationship. When creating a Farm you can add multiple images which gets added as individual products with the Farm as the foreign key. As I was working on being able to update the name of the farm I also wanted to add the ability to add more products on the same page. So I wrote a post function that is similiar to the one I used for creating the farm. However when I submit the update it doesn't only update and add the new products, it also creates a new farm object with the same name. I think I have to get the correct instance for this to work but I don't have enough experience with Django to know where I need to implement those changes. (I might also have to change from the UpdateView to something else, if so please let me know!) Here is my UpdateView: class FarmUpdateView(UpdateView): model = Farm fields = ['title'] def post(self, request, *args, **kwargs): farm = self.get_object() form_class = self.get_form_class() … -
How to set product attributes to basket line and order line in Oscar?
I'm new to Django-oscar and working on Basket now I can add products as lines to the basket easily but what if I want to choose a specific Product attribute to add to basket for example product A has attributes {'size': ['M', 'S'], 'color': ['red', 'blue']} what should I do if I want to add product A with size M and the color blue to the basket? Then I want to store and show the selected option attribute, (for example a customer choose product with color 'red' and size 'M'), then I need to show the selected attributes by the customer in the cart page and order pages also. I have created an attribute of type multi-option, how can I manage this?
