Django how can I get this translated markdown to render correctly on a website?
I've taken text from my models and used markdown python extension to turn it into html... but it renders as html as a string on my site like this: bot: <p><code>62%</code> Not quite. You got this! Appreciate your efforts</p> kaik: <p>ss</p> Rather than showing the html as a string, I'd like it to format it as html. My views.py currently: from django.shortcuts import render from .models import ChatStream from django.http import HttpResponseRedirect import random import markdown from django.template import RequestContext def send(request): message = request.POST.get('userMessage', False) ip = visitor_ip_address(request) response = routes(message, 'website_' + str(ip)) chatItem = ChatStream(ss= markdown.markdown(response), user= markdown.markdown(message), name=ip) chatItem.save() return HttpResponseRedirect('/chattr/') I'm using markdown to convert the text in my models ChatStream into nicely website formattable text, but rather than formatting as html it just prints the html as a string onto the site. my chattr.html: {% for chat_stream in chat %} <p> {% if forloop.last %} {% else %} <b>bot:</b> <br> {{chat_stream.ss}} <br> <b>{{user}}:</b> <br> {{chat_stream.user}} <br> {% endif %} </p> {% endfor %} It should look like this in the website: bot: 62% Not quite. You got this! Appreciate your efforts kaik: ss -
Load Apache-arrow.js to Django project
Learning web development and using Django. My app will consume lot of data and was thinking to integrate Apache-arrow.js I was inspired by the below blog on the apache arrow js website ( https://arrow.apache.org/docs/js/ ) : https://observablehq.com/@theneuralbit/introduction-to-apache-arrow for Django , I have setup the static folder in which I downloaded the es5-umd version. in my html I have the below : Adding type=="module" - doesn't help and console log do not print "test2" or "test1" I copied the example from apache arrow js website just to test. I get the error - " :arrow.js:20 Uncaught TypeError: Cannot read property 'Arrow' of undefined" {% load static %} <html lang="en"> <head> <script src="{% static 'js/apache-arrow/es5-umd/arrow.js' %}" > console.log('test1') </script> <script type="module" src="{% static 'js/apache-arrow/es5-umd/arrow.js' %}"> const LENGTH = 2000; const rainAmounts = Float32Array.from( { length: LENGTH }, () => Number((Math.random() * 20).toFixed(1))); const rainDates = Array.from( { length: LENGTH }, (_, i) => new Date(Date.now() - 1000 * 60 * 60 * 24 * i)); const rainfall = Table.new( [FloatVector.from(rainAmounts), DateVector.from(rainDates)], ['precipitation', 'date'] ); console.log('test2') </script> <script > console.log('test3') </script> Not sure what is issue , next I am thinking of trying browserify. -
Django 3.2.6: Path order in app urls.py related to 404
I have multiple paths in my urls.py file for app communities. Here are the two that are causing issues. path('posts/<str:username>/<slug:slug>',communities_views.viewPostDetail,name="post_detail") path('posts/delete_comment/<int:comment_id>',communities_views.viewDeleteComment,name="delete_comment") For some reason, Django seems to get confused about the order of these two paths. When in the order as shown, Django recognizes that delete_comment is a path (meaning that in templates using something like communities:delete_comment does not throw an error when generating the template), but when attempting to navigate to the url, Django keeps catching the post_detail view and freaks out. However, when I reverse the order of these two urls, everything works fine. Does order matter? If so, that is rather inconvenient for larger projects. If any other information is needed, please let me know. -
How to change the height of the parent div of a plotly_app iframe in python/django?
I am trying to change the height of the parent div of an iframe but cannot find out how to. Here is an image of how the html structure is when I use my Google browser's inspect tool (I did not write this html, it is created by plotly): The highlighted div contains the height that I am trying to change. Currently, the height is set to 0. (padding-bottom is set to 10% since the ratio in the html is set to 0.1 since I have been testing everything I can think of but I have the ratio set to .35 The following shows how I call the plotly_app in the html: Here is how the views.py has the scatter_app layout: I have attempted to add 'height': '90%' the styles of the 'html.Div' and the 'dcc.Graph' but these change the height of the html inside of the iFrame. Therefore, nothing changes since I need to change the height of the parent div. Thank you in advance for all the help. -
Properties that relate to each other as a one to many field problem
Sorry that the title might be confusing but I'm not native english speaker and very new to django terms. I have a scenario like this: A department can have many branches. I have a student model where he has two properties, Department and Branch. When I select his department , I want it to accept (and show in admin panel) only the branches that are related to that department , my code so far is this: class Entity(models.Model): id = models.UUIDField(primary_key=True , default = uuid.uuid4, editable=False) class Department(Entity): name = models.CharField(max_length=100, null=False) class Branch(Entity): name = models.CharField(max_length=100, null=False) dep = models.ForeignKey(Department, related_name='branches', on_delete=models.CASCADE) class Student(Entity): #Some Fields here department = models.ForeignKey(Department, related_name='students', on_delete=models.CASCADE) branch = models.ForeignKey(Branch, related_name='students', on_delete=models.CASCADE) Assuming I have a 2 departments (CE and CS), CE has 2 branches and CS has 3 branches , What I want is, when I choose a student's department, I want the branches to be shown only the one that exists on that department , what I'm getting is 5 branches (in this example). How can I solve this ? NOTE: I haven't played with anything related to the admin panel except registering the models. Thanks in advance and sorry if the … -
How to script interactions with Django POST endpoints?
What is the preferred way of pre-populating database (Model) objects in a Django app? I am inclined to try to script POSTing data to the relevant endpoints, but am being stymied by the CSRF protection. This is not part of the testing framework, this is for setting up demonstration and training instances in a beta testing or production environment. As a notional example, I'd like to populate the the "Player" database with three entries: Alice(sender), Bob(reciever) and Charlie(eavesdropper), and I'd like to script/automate the process of creating these entries after deploying and starting the application. I already have a form based mechanism for creating new Players. By visiting /create via a browser, there is a form that allows a person to type in the name, e.g. "Bob" and a role, e.g. "reciever", and submit the form to create the new Player instance. Thus it makes sense to me to try to try to use the existing web API for this: e.g. make calls like requests.post('0.0.0.0:8000/create', data={'name':'Bob', 'role':'reciever'}) in the script that pre-populates the database. However doing this results in 403 errors due to the CSRF tokens, which I don't want to disable. This problem also occurs if I just try … -

Get decimal data from Postgrades database using Django
I use Python and the Django framework to get some decimal data from the PostGress database. My question is that the variable "new_poi_lat" is displayed correctly, but why is the variable "poi_lat" displayed as shown below ?! I want the "poi_lat" variable to be displayed normally.

Wrong field value in Django FileField
There are models: class DataFile(models.Model): title = models.CharField( max_length=100, help_text='Краткое наименование данных', verbose_name = 'Наименование' ) file = models.FileField(upload_to ='data/', verbose_name = 'Файл данных', unique=True) .... class Map(models.Model): .......... data_file = models.ForeignKey( DataFile,on_delete=models.CASCADE, verbose_name = 'Файл данных', to_field='file' ) .......... I have an object of class Map. However, when referring to him obj.get().data_file.file.path or obj.get().data_file.file its behavior is different for django-shell and actual work. For Django-shell, a manual request gives the full path, which is what I need (stored in the 'file' field of the DataFile class). But in real work it outputs the value of the 'title' field of the DataFile class). I need the output to be exactly the full path to the file, i.e. what is stored in the file field. -

Django Custom Middleware gets AnonymousUser even for logged in users

Django Model Fields: Keeping track of list of possible items
I'm creating a Django model, where (as a simplified example) a user group (Users are all assigned to a group) will be able to access files of a certain file type, and which types a group can access will change by group. The list of files can be any of ~10 common file types. This list might change, but that's probably not common. Roughly speaking, I see two ways of doing this. Representing the file types as a list of strings for each user [".jpg", ".txt", ".zip"] or, as a 1:M relationship with some sort of "FileExtension" Object. These are cases in which I imagine the ORM route would be much preferred (Ex: If it's important to keep track of Each file extension's use case as for "image", "text", "audio", etc) But what if there's no other information we really need to consider here but the file extension itself? Is there a reason to create a whole model for just a few strings? In my actual project, I want to avoid the complications of creating and maintaining multiple models and storing those in the DB if I can. Rough Possible Code Examples of each: String/List approach: class UserGroup(models.Model): group_name = … -

Django how to loop through a model but not inclide the last entry
I'd like to loop through every entry in a django model except the very last item inside of a template. I understand how to do this in python, but unsure of how I might do it inside of a template.
