What is the correct way to store images in Django backend?
Hello I am new to Django, mostly experienced in Node and mongoDb, I have figured out how to store save media such as images on the Django backend. And can retrieve the image on the client/frontend side. Yet all uploaded media to the site is saved in a media/files directory in the backend in their png/jpg formats. I am a bit confused if this is how it should be saved? I thought it would be converted into bytes and saved in the sql database. Just a bit confused as in mongodb there are npm packages that convert the media into bytes and save it the database ie: images are not kept in png/jpeg format. -

How do I build a django chat app with multiple chat rooms?
I've build a real time chat app using django channels, but all the users can only connect to the same chat room even if they're in a different urls, there is only one websocket connection, I want to know how I can make it so each chat room url would be a different websocket connection.

How to update all parts of a web page containing the same object without reloading the page?
I'm using Javascript to make part of my web page editable for logged-in admin users. In one page, I have cards that display information about three people from the database. The cards contain username, skills, and bio fields. The username is also used a second time in the bio. When the edit button is clicked, the first username, skills, and the bio without the username become editable. And when I change the username and click on the save button only the first username changes. For the one in the bio to update I need to reload the page even though they have the same id in my HTML template.

How to create single column Filter (Choices) Drop-down (select) Django form?
Good day! I would be very grateful for any help. I have a model. There are repeating elements in one column of this model. I want to inject the result of a query into a view. The result of a query with a single column filter. That is, it turns out that I want to take from the model only those rows of the table -->> where the value is equal to the one selected from the drop-down menu (in a simple filter form). ['Gary', 'Henry', 'Shtefan', 'Villi'] For example, select only those rows in the row (empname) whose value is equal to Shtefan. Without the use of a static, manual entry in the code. Since it is possible that when the model table is replenished - with new data - there will be additions with other names. Is it possible somehow to take unique values without duplicates from the corresponding column and automatically use them in the filter? To be placed in a drop-down menu form (in a simple filter form). static class Developer(models.Model): JUNIOR = 'JR' MIDDLE = 'ML' SENIOR = 'SR' LEVEL_CHOICES = ( (JUNIOR, 'Junior'), (MIDDLE, 'Middle'), (SENIOR, 'Senior'), ) name = models.CharField(max_length=200) level = models.CharField(max_length=2, … -
Vitejs/Rollupjs/Esbuild: bundle content scripts for chrome extension
How to correctly bundle content scripts for a chrome extension using Vite.js? Content scripts do not support ES modules (compared to background service worker), so every content script javascript file should not have any import/export statements, all libraries and other external imports should be inlined in every content script as a single file. I'm currently using the following vite configuration, where I programmatically pass all my content script paths as the entry. vite.config.ts export const extensionScriptsConfig = ( entry: string[], outDir: string, mode: Env, ): InlineConfig => { const config = defineConfig({ root: __dirname, mode, build: { outDir, emptyOutDir: false, minify: false, copyPublicDir: false, target: 'esnext', lib: { entry, formats: ['es'], fileName: (_, entry) => entry + '.js', }, }, }); return { configFile: false, ...config }; }; entry contains the following paths Directory: C:\Users\code\extension\src\content-scripts Mode LastWriteTime Length Name ---- ------------- ------ ---- -a--- 15/01/2023 14:11 1135 inject-iframe.ts -a--- 15/01/2023 14:11 2858 inject.ts -a--- 14/01/2023 17:49 223 tsconfig.json The setup above works correctly - each content script is a separate file with no import.

Why is path imported once in Settings. py and again in urls.py in Django
I am new to Django. I noticed that path command is imported once in Settings.py and then again in Urls.py. From the name "Settings.py", I assumed that Settings.py will always get loaded first when we run a project as it contains, again as I assumed, the settings to be applied for the project. If that is correct, then why does path get imported again in Urls.py when Django already imported this once in Settings.py? If not, can you please elaborate so I understand why Settings.py and Urls.py can run independently. I did try to google to see if I could get the answer myself but did not find any. Thanks. -
How to upload an image using a post api in django

As for vue part, I used axios to send my post request as follows: submitData() { const formData = { sellerEmail: this.sellerEmail, image: this.productImage } axios .post("/api/v1/sell-bike/", formData) .then(response => { console.log(response) }).catch(error => { console.log(error) }) }, where in the template I am getting the inputs like this: <input type="text" v-model="sellerEmail"> <input … -

What is this kind of validation called? And how would I achieve it? Also, I am happy to learn other ways to implement this, if another database structure would be better. -

Enabling gzip compression for CSS and JS files with Django compressor on Heroku
I am currently working on a small Django project that is deployed on Heroku. In order to optimize the website's performance, I decided to use the django-compressor package to merge and minify all the JavaScript and CSS files. I am using the offline compression option, as it is the only one that works on Heroku. However, I have noticed that the compressed CSS and JS files are not being gzipped when delivered to the client. This is causing the benefits I gained from using the compressor to be lost. I have been trying to find a solution to this issue, but I have not been able to find an easy way to turn on gzip for the compressor when using offline compression. I would like to avoid a complex setup with S3, as this is a small site and I am looking for a simple solution that can be easily implemented on Heroku. My question is: Is there an easy way to turn on gzip for compressor when using offline compression? And how can I implement it on Heroku? I would greatly appreciate any help or suggestions on how to solve this problem. Thank you in advance. -

Custom django inlineformset validation based on user permissions
The objective is to have a simple workflow where an order and associated orderlines (created in a previous step) needs to be approved by the relevant budget holder. The approval form shows all order lines but disables those lines that the current user is not associated with (they should be able to see the overall order but only be able to edit lines that they are permitted to). They should be able to add new lines if necessary. The user needs to decide whether to approve or not (approval radio cannot be blank) The initial form presents correctly and is able to save inputs correctly when all values are inputted correctly - however, if it fails validation then the incorrect fields get highlighted and their values are cleared. models.py class Order(models.Model): department = models.ForeignKey(user_models.Department, on_delete=models.CASCADE) location = models.ForeignKey(location_models.Location, on_delete=models.CASCADE, null=True) description = models.CharField(max_length=30) project = models.ForeignKey(project_models.Project, on_delete=models.CASCADE) product = models.ManyToManyField(catalogue_models.Product, through='OrderLine', related_name='orderlines') total = models.DecimalField(max_digits=20, decimal_places=2, null=True, blank=True) def __str__(self): return self.description class OrderLine(models.Model): order = models.ForeignKey(Order, on_delete=models.CASCADE) project_line = models.ForeignKey(project_models.ProjectLine, on_delete=models.SET_NULL, null=True, blank=False) product = models.ForeignKey(catalogue_models.Product, on_delete=models.CASCADE) quantity = models.PositiveIntegerField() price = models.DecimalField(max_digits=20, decimal_places=4) total = models.DecimalField(max_digits=20, decimal_places=2) budgetholder_approved = models.BooleanField(null=True) def get_line_total(self): total = self.quantity * self.price return … -
