Django: Call a view function into another view function
my todo list has two different functions add_task & view_task I don't want to create one single function I want that view task will call add task # Add Task Page def add_task(request): submitted = False if request.method == "POST": form = TodoForm(request.POST) if form.is_valid(): form.save() return HttpResponseRedirect('/add_task?submitted=True') else: form = TodoForm if 'submitted' in request.GET: submitted = True return render(request, "core/add_task.html", {'form':form, 'submitted': submitted}) # Task List Page def view_task(request): task_list = Todo.objects.all() #This is the part of view_task function where I have been trying to call add_task function # If you see a few lines below, I am calling already form, return render(request, "core/view_task.html", { 'task_list': task_list, #'form':form, }) -
Define multiple templates for a block
I am moving a site over to wagtail and decided to use the codered extensions. The library comes with a image-gallery content-block. I want to use this but define a few templates that you can choose from in the admin ui. Normally you define a template in the meta section but I noticed there is a dropdown in the admin ui for template. How do I add a template to that dropdown? Link to the content block I want to change I am interested in adding a html template and not inheriting from the content-block to change behaviour. (Unless inheriting is the only way to add a template to the dropdown) -
django NoReverseMatch not a valid view function or pattern name
I am having problems with an old project that was running on a deprecated django version. I updated django to 4.1.5 and made a few edits to the urls.py files that they were using python from django.conf.urls. I changed this to use re_path but now am running into an issue I have not been able to resolve. The server starts up okay however when I try to access any of the pages, I get the following Error: Error: NoReverseMatch at /control/ Reverse for 'control.views.set_notes' not found. 'control.views.set_notes' is not a valid view function or pattern name. Looking at the Trace here is where it looks like the error is happening from url line below: $.ajax({ url: "{% url 'control.views.set_notes' %}", type: "POST", data: { 'csrfmiddlewaretoken': '{{ csrf_token }}', 'notes' : notes }, error: function (error) { alert("error setting notes to " + notes); }, success: function (response) { } I have my root urls.py setup as follows: from django.urls import include, re_path urlpatterns = ( re_path(r'^control/', include('control.urls')), re_path(r'^profiles/', include('profiles.urls')), re_path(r'^roasts/', include('roasts.urls')), ) My other control.urls.py setup is as follows: from django.urls import re_path import control.views urlpatterns = ( re_path(r'^$', control.views.index), re_path(r'^get_state/$', control.views.get_state), re_path(r'^cancel_profile/$',control.views.cancel_profile), re_path(r'^get_profile/$', control.views.get_profile), re_path(r'^set_temp/$', control.views.set_temp), re_path(r'^set_notes/$', control.views.set_notes), re_path(r'^add_marker/$', … -

Python Openpyxl library cannot deal with automatic row height
I'm currently using Openpyxl in a Django project to create an excel report. I'm starting from a blank excel model in which column C has text wrap enabled. Infact when I open the model and populate manually a cell I correctly get this But when I run this trial code wb = openpyxl.load_workbook(fileExcel) sh = wb["Rapportini"] sh["C3"]="very very very very very very very very very very long row" wb.save(fileExcel) this is the result I know openpyxl (strangely) cannot set row autoheight. I also tried to set wrap_text = True in the cell, but no way... any ideas ? -

How to limit the number of fetched children in django-treenode
I have a comment Model, where a comment can be a root item or under another comment. I'm using REST API to get the full tree. Is it possible to limit its depth, so for example It will stop after 3 nodes from each root comment. I want to add a "more" feature instead of show the whole tree at once. ` class CommentSerializer(serializers.ModelSerializer): leaf_nodes = serializers.SerializerMethodField() class Meta: model = Comment fields = [ 'id', 'body', "leaf_nodes" ] def get_leaf_nodes(self, obj): return CommentSerializer(obj.get_children(), many=True).data ` I tried looking at the documentation on GitHub but didn't find a solution. -

how do python async behaviour behaves with api requests?
I've been into Python/Django and things are going good but I'm very curious about how django handle any asynchronous tasks for example if there is a database query that took 10 seconds to execute and another request arrives on the server during these 10 seconds? def my_api(id): do_somthing() user = User.objects.get(id=id) # took 10 sec to execute do_somthing_with_user() I've used the queryset method that fetch something from database and let's say it took 10 seconds to complete. what happens when another request arrives on the django server, how django respond to it? will the request be pending until the first query responds or will it be handled in a parallel way? what is the deep concept for it? How Python Handles these type things under the hood? -
Cannot import name 'DEFAULT_STORAGE_ALIAS' from django.conf
I've setup a project that uses memcache and got it working properly but suddenly it stopped working and I just can't figure out why. According to the traceback is something that has to do with Django itself but that would be odd. So I'm asking you guys for help to help me figure out what's going on with this error. I haven't seen anything similar. Any clue?

What is the best pathway for building a django-rest api for a project?
I am about to begin a major project using Django-rest framework. I know that there is no "Correct" coding practice for anything, but I would still like to know what should be the path to follow for an easy and quick development experience. Should I be done with the Custom user models, user registration, and authentication first and then add the database model for other stuff? Or should I prefer another course of action? Thank you in advance. -
Write Django QuerySet that remove all whitespace from specific Keys within a JSONFIELD
I would like to write a Django QuerySet that removes whitespaces from Specific Keys within a JsonField. I have a django model with a JsonField type.

400 Bad Request Django/React
I have built a server with Django and I am receiving a 400 Bad Request within Postman when I check the POST method. However, it is displaying the JSON data within the Postman as well. Originally, I thought it was a frontend issue, because my console log was stating AxiosError {message: 'Request failed with status code 400', name: 'AxiosError', code: 'ERR_BAD_REQUEST', config: {…}, request: XMLHttpRequest, …} As I stated before, the error is showing in Postman so I'm assuming it's actually a server issue. Im real "finicky" when it comes to file colors, and if it is any color than the default color, I feel like there is errors within the file. Could these orange/beige files contain the problem? If I click on one of those files Im met with: The file is not displayed in the editor because it is either binary or uses an unsupported text encoding. Because I am new to django, I don't want to do something that's going to create an even bigger problem than what I already have.

How to save a raster in RasterField after save in GeoDjango?
I am building an app using Django with PostGIS backend. Thus, GeoDjango. I have a model with FileField, and RasterField [1]. I want to save a raster object to RasterField after supplying the FileField. I am trying to achieve this using a post_save signal. class Layer(models.Model): name = models.CharField(max_length=50, blank=True) file = models.FileField( upload_to='layers', null=True, max_length=500) raster_file = RasterField( null=True, blank=True, ) After some research [2], you have to use GDALRaster [3] to make the raster as an object. In my signals: from django.contrib.gis.gdal import GDALRaster from data_management.models import Layer @receiver(post_save, sender=Layer) def create_raster(sender, instance, **kwargs): instance.raster_file = GDALRaster(instance.file.path) instance.save() When I am uploading the file in my admin, the raster_file is not filled and not created.

How can I remove the navbar in these three parts in my python project?
I am currently trying to build a website with python django. At the moment I am making a dashboard for the website. On the dashboard I want to show three tiles for different menu options. Dashboard Ignore the content this is just a placeholder for now. As you can see in every part of the dashboard the navbar is included. My code for the dashboard looks like following: {% extends 'base.html' %} {% block titel %}Dashboard{% endblock %} {% block content%} <div class="container-fluid"> <h1 class="fw-bold">Dashboard</h1> <div class="row"> <div class="col-sm-4"> <div class="card"> <div class="card-body" > {% include 'todolist/index.html' %} </div> </div> </div> <div class="col-sm-4"> <div class="card"> <div class="card-body"> {% include 'todolist/index.html' %} </div> </div> </div> <div class="col-sm-4"> <div class="card"> <div class="card-body"> {% include 'todolist/index.html' %} </div> </div> </div> </div> </div> {% endblock %} The base for all the sites are in a extra file called base.html. In this file is also the navbar defined. How can I prevent that the navbar will be in every part of the dashboard while still using the extends part?
