How to add User objects to manytomany fields?
I am trying to add the currently logged in user to a m2m field in my model: class(models.Model): name = m.cfield(...) admin = m.m2m(User, related_name="admin+",...) members = m.m2m(User, related_name="members+",...) creator = m.FKEY(User, related_name="creator+",...)

Django 2.1.5: Storing the current username in a blog entry
I am very new to Django and try to build a little app for my family with some basic features, one of which is a blog app. In this now I want to store the author of a blog entry in the article model to save it in the database. In the end in the blog entry I want a header that displays the author and the datetime. I found several approaches to that but some how none of them worked for me so far. The last thing I did now was to try and grab the username in the view with requests.user.get_username() and then populate the field in my form with this string as initial value. Somehow it just doesn't come through, I always get the "field is required" error message... Here is my blog-create-view.py: def blog_create_view(request): user = request.user.get_username() data = {'author': user} form = BlogForm(request.POST, data) if form.is_valid(): form.save() return HttpResponseRedirect('/blog/blog-create/thanks') else: print(form.errors) form = BlogForm() context = { 'articleform' : form, } return render(request, "blog-create.html", context) this is the form: class BlogForm(forms.ModelForm): title = forms.CharField(label='', widget=forms.TextInput(attrs={"placeholder":"Titelfeld"})) text = forms.CharField( label='', widget=forms.Textarea( ) ) author = forms.CharField(widget=forms.HiddenInput()) class Meta: model = Article fields = [ 'title', 'text', … -
Remove 1 Form from Formset Dynamically Django
I am using the below to dynamically add a form to my formset: .html {{ form2.management_form }} <div id="form_set"> {% for form2 in form2.forms %} <table class="table table2" width=100%> <tr> <td width = 17.5%>{{form2.ProductCode}}</td> <td width = 32.5%>{{form2.DescriptionOfGoods}}</td> <td width = 12.5%>{{form2.UnitQty}}</td> <td width = 12.5%>{{form2.Type}}</td> <td width = 12.5%>{{form2.Price}}</td> <td width = 12.5%>{{form2.Amount}}</td> </tr> </table> {% endfor %} </div> <button id="add_more" class="btn aqua-gradient">Add</button> <button id="delete" class="btn aqua-gradient">Delete</button> <div id="empty_form" style="display:none"> <table class='table table2' width=100%> <tr> <td width = 17.5%>{{form2.empty_form.ProductCode}}</td> <td width = 32.5%>{{form2.empty_form.DescriptionOfGoods}}</td> <td width = 12.5%>{{form2.empty_form.UnitQty}}</td> <td width = 12.5%>{{form2.empty_form.Type}}</td> <td width = 12.5%>{{form2.empty_form.Price}}</td> <td width = 12.5%>{{form2.empty_form.Amount}}</td> </tr> </table> </div> $('#add_more').click(function() { var counter=0; var form_count = $('#id_form-TOTAL_FORMS').val(); counter++; $('#form_set').append($('#empty_form').html().replace(/__prefix__/g, form_count)); $('#id_form-TOTAL_FORMS').val(parseInt(form_count) + 1); }); This works perfectly - however I need to be able to delete a line dynamically as well when the Delete button is clicked, and I'm struggling with working through the best way to do that. Any suggestions? I had tried this below - but of course that will only delete all forms and only if they are empty. I want to just delete one form at a time. I feel I may need to add a counter to the id above? Please … -

Will I be able to use celery tasks during model migrations in Django?
I have a requirement to modify an existing db model called Alert and create new alerts with new functionality. I also need to take care of the existing alerts in the data base which were created with old model fields. After adding the new fields to Alert model, I'm trying to re-create the alerts with new functionality which has new columns. Basically taking existing rows and re-inserting them in data base with updated new columns with some extra information in the new columns. For this I'm trying to run a celery task in the function which is called as soon as the migration is applied. migrations.RunPython(function which does some operation and then run celerytask.delay(with_some_args) to create new alerts) I'm really concerned whether I can run a celery task inside the function which is passed to migrations.RunPython(). Even for testing this functionality, I don't have an existing data in our lower environment and the required migrations are already applied before even including this function. I don't want to mess with existing DB as everyone is using already. Can someone please confirm if I can actually run long running celery tasks when applying the migrations? in python manage.py migrate appname? Django: 1.11.15 … -

ModelForm is creating a new record inspite of providing an instance
I am creating a ToDo list where I can create a ToDo item and provide a button against each item to update it. I am using ModelForm to save my data to DB. The update button takes me to 'update.html' with the instance of selected task. But when I update the task information and click on 'Submit', it creates a new task with the updated information and does not update the same task. Please helo me, I am stuck. views.py from django.shortcuts import render, redirect from .models import Task from .forms import * def index(request): tasks = Task.objects.all() form = TaskForm() if request.method == 'POST': form = TaskForm(request.POST) if form.is_valid(): form.save() return redirect('/') else: context = {'tasks':tasks,'form':form} return render(request,'TaskList/list.html',context) def update(request, pk): task = Task.objects.get(id = pk) if request.method == 'POST': form = TaskForm(request.POST, instance=task) if form.is_valid(): form.save() return redirect('/') else: form = TaskForm(instance = task) context = {'task':task, 'form':form} return render(request,'TaskList/update.html', context) urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name = 'list'), path('update/<str:pk>/', views.update, name = 'update') ] update.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <form method = 'POST' action = ''> {% csrf_token … -
Python Django views .home dividing into sub classes
I'm trying to do a platform which is querying some data from different social media channels. My "Home" Class is now full of these queries and it takes up to 10 seconds to load the page. My question would be how I can divide the Home class into sub classes like this. Currently my code looks like this: def Home(Request): function1() function2() function3() function4() context{ query1: "query1", query2: "query2", query3: "query3", } return render(request, 'base.html', context) But I want to do like this: def Home(Request): function1() context{ query: "query" } return render(request, 'base.html', context) def Home-query2(Request): function2() context{ query2: "query2", } return render(request, 'base.html', context) def Home-query3(Request): function3() context{ query3: "query3", } return render(request, 'base.html', context) Other question would be, how can I first load the home class and then load each query all at the same time. So that I that load time totally is decreased.
