How to resolve Key Error Exception when accessing dictionary key inside an if statement
I'm currently developing EV calculator using python and django. I get a key error exception when trying to access a dictionary key in an if statement inside a function. To break it down, my calculator function does the following, prompts the user for four input values, wager_amount, odd1, odd2 and odd_to_bet/back_odd, based on values user has entered, the function will output expected value or ev in jinja html. Something to note is, odd_to_bet/back_odd must either be equal to odd1 or odd2, if odd_to_bet/back_odd is either not equal to odd1 or odd2, the function has an else block with a message to tell the user to Please, check the odds again for any typo error!. An example: lets say the user inputs the following values from html form wager_amount = 10 odd1 = 1.54 odd2 = 2.47 odd_to_bet/back_odd = 1.54 This works fine, i'm able to display output without issues the key error exception arises when the user inputs and submits odd_to_bet/back_odd a value not either equal to odd1 or odd2. wager_amount = 10 odd1 = 1.54 odd2 = 2.47 odd_to_bet/back_odd = 1.52 My expected output should be "Please, check the odds again for any typo error!." displayed in the html. … -

HTML name/value button attribute not being sent via POST request to server
I am currently using HTMX and Django to process button clicks within a table that adds the selected item to a list. I have the following form code: <form action="" method="post"> {% csrf_token %} <button hx-post="{% url 'add-analysis' %}" hx-target="#analysis-list" type="submit" name="projectChoice" value="{{project.project_title}}">Add</button> </form> in my Views.py I am trying to parse the data with the following code: print(proj_name = request.POST.get("projectChoice")) This returns None however. To debug this I tried listing all of the POST requests to the server with the following: print(list(request.POST.items())) However this only returns the CSRF token, what am I doing wrong here? -

How to display extra context and form fields at the same time on django template using class based view?
I am trying to display some extra context on the page, but when I adding get_context_data method it is displayed context but not a forms fields.

Multiple Git push in one command
I've an application that requires to run git add/commit/push on each single file i'd like to push, in order to trigger a Gitlab Job on each. My problem is that git is actually taking many time to do the git push command. Here are the commands i'm using: git add myFile.json git commit myFile.json -m "commitMessage" variable1 = git rev-parse HEAD # Storing last commit hash into a variable # Pushing only one specific commit to (maybe) make it faster git push $variable1:master What i'd like to do is to make the whole process "faster". What i've thought about: Doing multiple pipeline triggers using only one git push (maybe by running the pipeline on each commit instead of each push), but it doesn't seem possible. Doing multiple pushes in one git push command, so it doesn't have to reload some of the git push init operations before each file pushed (i have no idea on what is happenning during the git push process, so that idea may be wrong) Does anyone has an idea on how to make this process faster, by using one of my ideas, or even a brand new one from you ! Thanks in advance ! -

Django query annotate after filter doesn't work correctly
I have two models that are related using a m2m relationship through an intermediate model. The relation field is called participants. When I do this: chats = Chat.objects.annotate(Count("participants")).filter(participants=user) chats.get(pk=11).participants__count It will return 2; which is correct.

How does "alternates" in the Django site framework work?

Submit form post from another view with input field
I am relatively new to Django and I'm making a small "social" project. It basically consists of user profiles, and on those profiles you can post "comments". I have a view that displays the comments each user has, and a separate view that allows you to post comments. This works as expected. The problem I am facing right now is the following. - I have an < input type=text > field in the view to view comments, and I want to be able to post a comment from there and have it saved in the database. I have tried grabbing the post kwargs in the form, but I couldn't get it to work correctly nonetheless have it save automatically. How can I get this done? Here is the code that I have so far.

Can I write posts for a personal Django blog website in static html files?
I'm pretty new to Django and have been experimenting making my own personal blog. General question I get that I can specify my blog post structure in models.py and use the admin site to write my blogs. However, what if I want to write my blogs in raw HTML files stored in, e.g. my-website/blog/posts/<list-of-html-blogs> and then have those files uploaded into the data base and shown on the website. Is there are a standard way of doing this? My initial approach is to create a Python function that reads in the HTML files as strings and uploads those files into the database manually, i.e. using something like blog.models.Post(title=my_title, content=html_as_string). Whenever I'd write a new blog, I'd then call this function to upload a specific html file. However, I have found very little online about whether this is the correct approach. Django blog overview If helpful, I'm showing below what my blog's models.py and views.py currently looks like. models.py from django.db import models STATUS = ( (0, "draft"), (1, "published") ) class Post(models.Model): title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=200, unique=True, null=True) date = models.DateTimeField() content = models.TextField(blank=True) status = models.IntegerField(choices=STATUS, default=0) class Meta(object): ordering = ["-date"] def __str__(self): return self.title …
