Aggregate number of likes for each day within period
I am building a REST Api on Django RF which represents a very basic social network. I have a model Post that has a value Likes which is related to a User by many to many through a Like model. My models: class Post(models.Model): content = models.TextField() created_on = models.DateTimeField(auto_now_add=True) author = models.ForeignKey(CustomUser, on_delete=models.CASCADE, related_name='posts') likes = models.ManyToManyField(CustomUser, related_name='likes', through='Like') class Like(models.Model): author = models.ForeignKey(CustomUser, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) liked_on = models.DateTimeField(auto_now_add=True) I need to aggregate a likes statistics for each day within a given period. For example, a request looks like this analytics/?date_from=2020-05-15&date_to=2020-05-17 And I need give something like this: [{ 'date': 2020-05-15, 'likes': 5, }, { 'date': 2020-05-16, 'likes': 7, }, { 'date': 2020-05-17, 'likes': 10, }] How can I do that in Django?

How to filter by known parameters in Django?
I have several parameters with values that you can select for filtering. The fact is that the admin can add other parameters and their values should also go to the get request and be processed on the server. It looks something like this: Country -checkbox- USA -checkbox- Germany Resolution -checkbox- 1920x1080 -checkbox- 5120x ... Other options .... That is, I have several filters there and it will look something like this: products = Product.objects.filter(Q(country=request.GET.get('country') || Q(resolution=request.GET.get('resolution')) But how to make the parameters by which dynamic become dynamic? -

Obtain a specific data from my model - Django
I'm trying to understand how to obtain some data from my models.

How to submit form using REST API for Django backend with CSRF enabled?
I'm trying to submit form to Django Web app using Java Rest Client. It doesn't work at all, I have no idea why. I was able to login using my client. I took csrftoken and sessionid cookies from login response I do submit form and provide csrfmiddlewaretoken=cookies.csrftoken.value I send csrftoken and sessionid cookies along with request. DJango backed doesn't recognise me and redirects to login. Why? I managed to figure out that for GET requests I need to send only sessionid cookie. DJango redirects to login if Cookie 'csrftoken' is sent along with GET request. What do I do wrong? It should be so trivial... -
Which ORM syntax to join three tables in Django?
I have the following three Models (tables) in my Django project: class Tool(models.Model): id = models.AutoField(db_column='Id', primary_key=True) name = models.CharField(db_column='Name', unique=True, max_length=50) class Flow(models.Model): id = models.AutoField(db_column='Id', primary_key=True) Toolid = models.ForeignKey(Tool, models.DO_NOTHING, db_column='ToolId') name = models.CharField(db_column='Name', unique=True, max_length=50) class Task(models.Model): id = models.AutoField(db_column='Id', primary_key=True) name = models.CharField(db_column='Name', max_length=50) FlowId = models.ForeignKey('Flow', models.DO_NOTHING, db_column='FlowId') I want to make ORM query that returns all info of Technology, Flow, and Task together that are related to each other (i.e. JOIN method in SQL queries). For example, I want to get something like this: [ { Tool name: ... Flow name: ... Task name: ... } { Tool name: ... Flow name: ... Task name: ... } ... ... ] Do you know what ORM sentence should I write to get that output? I really want to get the result from all of the three tables (not only from two of them)! It would be really appreciated if you provide me with the syntax related to my tables I provided above. Thanks a lot! -

How to add a string to my blog post path instead of integer with get_absolute_url in django?
I'm working on a simple blog project and have been following Corey Schafer on YouTube. In the tutorials, he creates new blog posts with integers (e.g. /blog/1, /blog/2, and so on), but I would like to create my post path with strings (like blog/my-blog-post, /blog/new-blog-post).

Django is not refreshing content without server start
I am working on DjangoRest Framework, if I update values from the API, and see the content on the frontend, the changes are not getting reflected without server startup. For debugging, I also directly changed the value in the database, but the changes are not getting reflected either in this case too. What could be the reason behind this? Can someone point me out in the right direction? I read about it and someone told this is happening because of .pyc files I even deleted them. But nothing solved my issue yet. How can i resolve it ? -
Django model choices from database, another model
I'm trying to figure out how to allow for a model to take only certain values. But I can't use IntegerField with choices option because it's product database with couple thousand products. To be more precise- I'm trying to create app which manages product orders.

Any idea what should I use? -

Which template tag to include an image stored using django-storage[dropbox]
I try to build my first application with Django, and use django-storage to store my media on dropbox: DEFAULT_FILE_STORAGE = 'storages.backends.dropbox.DropBoxStorage' DROPBOX_OAUTH2_TOKEN = ---- mytoken ---- DROPBOX_ROOT_PATH = 'media' It works well to upload and display the images using the models directly (e.g. {{ object.photo.url }} in the html template works) However, how can I create a link to the image in the template if I have no object. Something like <img src="{{media_url}}/myimage.jpg"> does not work as media_url points to localhost (on my local server). Is it needed to redefine media_url or is there another tag to use? -
How to configure NGINX for Vue and Django?
I was following this tutorial to create backend and it worked. I made simple a Django REST admin panel to upload images, it worked. Then i created Vue frontend app, run 'npm run serve' while in 'VScode remote' and it worked (images are fetched from django and styled by Vue in my localhost). The PROBLEM is it's not obvious how to make all this work in production vps server (i mean from Vue 'dist' folder after 'vue run build'). Everything i tried just gives me 404 error or ruins Django admin panel. Here are my NGINX settings : server { server_name kruglovks.xyz www.kruglovks.xyz; client_max_body_size 100m; location = /favicon.ico { access_log off; log_not_found off; } location /static { root /home/kirill/myprojectdir/myproject; } location /media { root /home/kirill/myprojectdir/myproject; } location /dist { try_files $uri $uri/ /index.html; alias /home/kirill/myprojectdir/myproject; } location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } Vue router is set to history mode. Please, i need some info how to make Vue work in this configuration. P.S. Maybe there is alternative way of using Vue alongside Django? Thank you so much and have a nice day!
