How to modify how Djongo ArrayModelField is shown in Django Admin
I'm experimenting with Djongo right now. So far a great project! What I don't like yet is the way ArrayModelField fields are integrated in the Django admin. I am missing something like an add-button. At the moment only one additional empty inline Form is shown for the nested model. Is there a possibility to add new inline models with an "add-button"? -
Unable to create django queries for the logic required?
I want help to create django query => select those journal names which matches some ledger1.name for any particular date range, also filter all transactions in which the ledger name exists in 'By' field, and aggregate their 'To' sides total. I have the following django models: class ledger1(models.Model): Creation_Date = models.DateField(default=datetime.now) name = models.CharField(max_length=32,unique=True) group_Name = models.ForeignKey(group1,on_delete=models.CASCADE) Opening_Balance = models.DecimalField(max_digits=19,decimal_places=2) class journal(models.Model): Date = models.DateField() By = models.ForeignKey(ledger1,on_delete=models.CASCADE,related_name='Debitledgers') To = models.ForeignKey(ledger1,on_delete=models.CASCADE,related_name='Creditledgers') Debit = models.DecimalField(max_digits=10,decimal_places=2,) Credit = models.DecimalField(max_digits=10,decimal_places=2) thankyou. -
Django sql-modifying onclick function
So I'm working on some Django app right now, which is basically kind of personal movie list. This app contains: Movie Model Custom User model I want this app to display every user's lists as well as the main list, which contains every movie. In this last list I want to add in every row a custom button with onclick function, that adds this certain movie to logged in user list and saves it. How and where do I make this function, to Add movie, which is in the same row, to a ManyToMany relationship with my user model? I tried to search how to do it, yet I didn't find a case, which contains onclick button actions, which modifies sql. Here's my code: Models.py from django.contrib.auth.models import User from django.db import models class Movie(models.Model): movie_id = models.PositiveIntegerField(default=0) title = models.CharField(max_length=100) director = models.CharField(max_length=50) year = models.CharField(max_length=4) kind = models.CharField(max_length=20) countries = models.CharField(max_length=50) class NormalUser(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) movies = models.ManyToManyField(Movie) Views.py from .models import NormalUser, Movie def index(request): movie_list = Movie.objects.order_by('-title') context = { 'movie_list': movie_list, } return render(request, 'PTWList/index.html', context) def userlist(request, pk): normal_user = get_object_or_404(NormalUser, pk=pk) current_user = request.user context = {'normal_user': normal_user, 'current_user': current_user, 'pk': ... -

django-money vs custom solution with minor currency
I'm just about to decide if I should use the django-money package or have my own solution, which allows me to work with minor currencies. I've read a lot that if you work with money you should always use minor currency or it's the better solution (I want to use stripe and I've seen that they are also handling the money in the minor currency). In order to get the minor unit I want to use this package (iso-4217). Does anyone have experience which solution is better? -

django {% get_current_language as LANGUAGE_CODE %} and session['_language'] are not equal until reload
In my app I can change the language by the following: from django.utils.translation import LANGUAGE_SESSION_KEY # LANGUAGE_SESSION_KEY is "_language" ... def my_view(request, my_lang=en): request.session[LANGUAGE_SESSION_KEY] = my_lang ... context = {"mysession": session} return render(request, "mytemplate.html", context) This works mostly as expected. However, the direct response of this view renders still in the previous language despite the session variable is set correctly. In other words the following template gives imho contradictory output: {% load i18n %} {% get_current_language as LANGUAGE_CODE %} <b>Debug:</b> current_language: {{ LANGUAGE_CODE }} session_variable: {{mysession|get:"_language"}} Note that, to access the attribute _language beginning with an underscore I have to use a custom filter, see this answer. Django-Output: Debug: current_language: en sessionvariable: de All {% trans ... } statements are handled to the (outdated) content of LANGUAGE_CODE, which is annoying. After changing the language the uses expects an immediate effect. If I refresh the page or load a different view, then the new language is used correctly. Do I understand something wrong? How can I achieve that the current_language is set correctly in the immediate response. -
Django Non-Managed Models - Querying from JSON file instead of Database
I want to have model that don't need to be created in database as table but use data from other sources like json files and other model objects. So I am using Non-Managed Model. This model is being created dynamically as described here in the docs Now Let me explain how I want to create the fields in this non-managed model. I have a json file that defines what fields should be in model, Let's call it contact-model.json. fields in this json file are mapped to django fields and dynamic model is created. This part is done. { 'model_name': 'Contact' 'fields': { 'name': 'CharField', 'email': 'EmailField' } } Now I have model that is storing all data related to above contact-model.json. Code for that model is given below class GenericAnswer(models.Model): answer = JSONField() model = CharField(default='Contact', max_length=30) And value of that asnwer would be { 'name': 'Adil Malik', 'email': 'sample@email.com' } What I want to do is that when I fetch Contact.objects.all(), It should return objects fetching from GenericAnswer based on model name, in this onctext, it is Contact. Can I do it. If Yes, Plese Explain How ???? -

Django, Hosting using Pycharm
I have to host a Django website onto the private server at my workplace. I'm using MySQL as the database (Through Wamp). The machine I'm using has Windows Server 10 installed on it. Is it advisable to use Pycharm's Deployment option? If so, What options and settings do i use? Is there any way i can map my IP address to a URL so that the users dont have to remember my IP Address? Is there any alternate/effective method that i could use? Also, I've disabled the IIS on the system so that i could use WAMP. {I faced a lot of issues downloading the database version that's compatible with all the files and WAMP was the easiest option i could find. It also comes with phpmyadmin, which helps as well. Also, Keep in mind that I'm still trying to figure everything about about Django and i dont know much} -

However, it doesn't return the details about the notification. I want all details about each notification, including the details about the post. So the output should be something like this: { "post": { "id": 1, "status": "Hello!", . . . }, "user": { "username": "Ben", "avatar": "example.png" . . }, is_read: 1, created_at: 2017-07-21, type: 2 } -

django : How to disable datepicker dates, based on the entries form db?
I have n number of dates defined in this below model in the database, these are directly inserted by admin, not by modelforms or anything. class Calendar(models.Model): date = models.DateField() occasion = models.CharField(max_length = 20) the form that has the date fields, class LeaveRequestForm(ModelForm): class Meta: fields = (... "from_date", "to_date" ...) model = Leave widgets = { ... 'from_date' : DateInput(attrs={'class': 'datepicker'}), 'to_date' : DateInput(attrs={'class': 'datepicker'}), ... } I have this datepicker script which disable weekends, <script> $(document).ready(function() { $('.datepicker').datepicker( { minDate : 0, beforeShowDay : $.datepicker.noWeekends } ); }); </script> Now I want to disable the dates defined in the database + weekends as well. How do I do that?
