Filter by Users Group
I only want to show buttons based on a user group. In this example I have a list of buttons then an IF Statement that checks if the user is in the group 'Recruiter', if they are then it displays some additional buttons: Is there an easier way to do this in the html, like {% if request.user.groups == 'recruiter' %} Views.py fields = request.user.groups if fields == 'Recruiter': fields1 = 'True' else: fields1 = '' context['fields1'] = fields1 html {% if fields1 %} a bunch of buttons {% endif %} -
How to use custom YAML file as API documentation in Django REST Framework?
I need to add API documentation to my project. I wrote my custom schema using swagger editor and now I have a YAML file as follows: swagger: "2.0" info: description: "This is the documentation of Orion Protocol API" version: "1.0.0" title: "Orion Protocol API" host: "127.0.0.1:8000" basePath: "/api/" paths: /api/decode: post: tags: - "pet" summary: "Decode the payload" consumes: - "application/json" produces: - "application/json" parameters: - in: "body" name: "body" description: "Packet data" required: true schema: $ref: "#/definitions/PacketData" responses: "405": description: "Invalid input" /api/encode: post: description: "Encoding configuration parameters for the devices" produces: - "string" parameters: - in: "body" name: "body" description: "Addresses and values of configuration parameters" required: true schema: $ref: "#/definitions/ConfigPayload" responses: "405": description: "Invalid input" definitions: PacketData: type: "object" required: - "payload" properties: payload: type: "string" description: "Packet string starting with 78" example: "78010013518BB325140400000500000AAA0000002A6E0000004AC05D00006A00000000" ConfigPayload: type: "object" properties: Addresses of the configuration parameter: type: "string" description: "According to the documentation of configuration protocol" example: "542" Now how can I add this to the project? Where it should locate in the project? May the views render this file? I need to have the following path: urlpatterns = [ path('documentation/', some-view-that-will-render-yaml) ] -
How to Use Q to filter using String
Suppose I can have these lists of strings(I already know how to get these list of strings from the user): {"title, "year", "stars"} and {"title"}. If I get the 1st one from the user, I want to filter the Movie objects such that it works like: Movie.objects.filter(Q(title__icontains=query) | Q(year__icontains=query) |Q(stars__icontains=query)). If i get the 2nd one from the user, it is like Movie.objects.filter(Q(title__icontains=query) We have assured that the string in the list is a field of model. -

Django user specific transfer of files/images/pdf
Consider there are two types of users 1. Creator. 2. Approver. The creator will upload a file and process it by clicking a button (by the way the file should not be in his queue) now, the file needs to move the approver and he will approve it and then the file needs to go back to the original creator. Any material links or suggestions about the same? -
Seeking advice what to continue learning [closed]
I am a young programmer(<15 years old) who has knowledge of Python, Java and C++. By basic, I mean enough to solve the first fifteen problems of Project Euler.https://projecteuler.net/archives To give an even better understanding, I was able to complete the Google's Code Jam - Qualification Round: Question A in a few hours. https://codingcompetitions.withgoogle.com/codejam/round/000000000019fd27/000000000020993c Most of programming knowledge rests in Python, since it is just so much easier. For a few days now I have been wondering whether to learn JavaScript, HTML and CSS to try and get started with Web Development, or to hook to a Python framework, specifically Django, or to give Data Science or Machine Learning a go and see if i can get the hang of the basics. I have almost no knowledge of algorithms. I one's I do know are bubble sort, and binary search. Which path should I take?? ( I am good at Math and have been trying to teach myself calculus. ) -

404 Error After Adding Argument To URL Path
Ive got a users profile page and an update_profile page. My projects urls.py: re_path(r'^profile/(?P<username>[\w-]+)/$', include('users.urls')), My users.urls: path('update_profile', views.update_profile, name='update_profile'), Prior to adding the username argument to the url both of these links were working. Since adding the username argument, I can access the profile page but the update_profile page throws a 404 error. My understanding is that if the address bar reads www.site/profile/testuser/update_profile the projects urls.py will strip the www.site/profile/testuser/ and pass just update_profile to the profile apps urls.py, which then should match the path ive given. Why isnt this working? On my profile page I have a check that ensures the username passed in matches the logged in user (so users can only access their own profiles). I will need a similar check on the update_profile page, but currently arent passing username to the update profile page. How could I perform this check without passing it in a second time like /profile/testuser/update_profile/testuser? Thank you. -

How to add styling in django templates inside for loop using css?
I am making a simple blog project in which I am trying to inject each post's data using for loop template tagging. But in doing so, the grid becomes distorted when css is applied on blog list template. However this css works perfectly fine when tested on manually added posts inside a separate Html page. How to fix this because most of the css that works fine on normal Html pages doesn't work properly when combined with django templates. Here is my Basic Blog Posts template: {% extends 'basic_app/base.html' %} {% block content %} <div class="centerstage"> {% for post in post_list %} <div class="cards"> <div class="card"> <img class="card__image" src="{{ post.blog_pic.url }}" alt=""> <div class="card__content"> <p> <a href="{% url 'post_detail' pk=post.pk %}">{{ post.title }}</a> </p> <p> {{ post.text|safe|linebreaksbr }} </p> </div> <div class="card__info"> <div> <i class="material-icons">{{ post.published_date|date:"D M Y"}}</i>310 </div> <div> <a href="{% url 'post_detail' pk=post.pk %}" class="card__link">Comments: {{ post.approve_comments.count }}</a> </div> </div> </div> </div> {% endfor %} </div> {% endblock %} Html Code that works fine on manually adding posts: <!DOCTYPE html> <html lang="en" dir="ltr"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" href="cards_style.css"> <title>Blog</title> </head> <body> <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet"> <div class="cards"> <div class="card"> <img class="card__image" src="https://fakeimg.pl/400x300/009578/fff/" alt=""> <div … -

Using Django localsettings.py with Elastic Beanstalk
I am using a combination of settings.py (saved in git) and localsettings.py (not saved in git) to configure my app and keep sensitive info out of git. I'm deploying the Elastic Beanstalk for the first time and can't figure out how to upload or create the localsettings.py in the correct place. If I scp it it appears as the ec-user and I can't create the file with the right ownership directly in the deployment directory. The ultimate setup for me would be to have a "master" file that lives just above the /var/app/current directory that I can copy into the correct place whenever I deploy. Any help would be appreciated. -

Is it worth learning ASP .NET Core - haven't learned C# / Django vs NodeJS [closed]
I started programming at Feb 2020 with python. I can only use javascript and python. I was looking for a web-framework because recently I felt like studying backend. I was thinking of Django or Node.js since they are like the superstars. But I watched a youtube video about this ASP .NET Core and it looked pretty awesome. So I'm kinda confused if I should just go with my original plan or study C#. And how do you guys think of Django vs Nodejs? Since I'm a newbie it takes me a while to learn any kind of thing. -

Django and ajax to update database without page refresh
I want a button click to result in my database being updated without a page refresh. I've researched this a lot, and it seems a jquery ajax call is the way to go. But it's not working. I put a check in to see if the click event is working, and the strange thing is that it only works when I click the first button in the table (the table shows all the user's words with a 'for loop'). But then I get a 404 error, so it makes me think that my mistake is in my views? Nothing happens when I click the other words - no error, no click event, nothing. But everything works (i.e. the database gets updated) without using jquery, but then of course the page updates every time. By clicking the button the word should automatically get added to the user's word list without a page refresh. I'm stuck with this, would really appreciate some help, thanks! So I need to find out: 1) how to get the click event working every time; 2) how to get the url right in js; and 3) how to get my view right. My template (without jquery): <a … -

Email codes from a defined list using Django and dealing with concurrency
I have a simple Django Rest server api that gets a post request by another app (a payment processing client). Every post triggers an email with one access code already defined by this model: class AccessCode(models.Model): code = models.CharField(max_length=64, blank=True) sent = models.BooleanField(blank=True, default = False) The general idea is for my view to query this model, get the top AccessCode, mark it as sent and send the email. Obviously I need to deal with concurrency. I'm thinking on a pessimistic approach, querying the database inside an atomic transaction and using select_for_update. class send_code(APIView): def post(self,request): with transaction.atomic(): code = AccessCode.objects.select_for_update().filter(sent=false).first() code.sent=True account.save() // send email with the code return True The thing is, during one active transaction, I don't really understand how the next requests will wait for the query to be release. Will this approach work with parallel post requests without expecting a lot of them to be rejected?
