Need to create a scheduling app in Django
I'm new to Django but love what it can do. Can anyone recommend the best method to create a scheduling app. The purpose is to visually show what projects each employee is working on each day in our department. Currently we use excel with each day of the month on the X axis and employee name on the Y axis which is not ideal. I've read a bit about Django Scheduler. Has anyone used this? -

Sending POST with checkbox value changes with Django
I have a table and in the table a form with fields the user can change. Three of these fields use check boxes. I'm able to reflect what is currently in the database after following this post, but I haven't been able to find something else for the next piece of the puzzle. The problem I'm having is that if a checkbox is set to true(checked) and then I unselect it, the POST data does not include anything that says that it is not checked anymore. It doesn't give a value of "off", "0" or false. How can I make sure that when the boxes are unchecked I still get those values("off", 0" or "false")? on the post data? Below is my code: <form id=result_form action= "{% url 'example:save_notes' %}" method="post"> {% csrf_token %} <table id="results_table" class="formdata" summary="Example Search Results" data-order='[[ 1, "des" ]]' data-page-length='25'> <thead> <tr> <th style="width:5%" scope="col">Search Method</th> <th style="width:20%" scope="col">Search Date</th> <th style="width:5%" scope="col">City</th> <th style="width:10%" scope="col">Example Name</th> <th style="width:10%" scope="col">Article Title</th> <th style="width:10%" scope="col">Article Link</th> <th style="width:5%" scope="col">Reviewed </th> <th style="width:5%" scope="col">J/J Related</th> <th style="width:5%" scope="col">N Related</th> <th scope="col">General Notes</th> <th scope="col">Findings</th> <th scope="col">Edit</th> </tr> </thead> <tbody> {% for result in results %} <tr> <td>{{result.notes.method}}</td> … -
Syntax warning in PyCharm when loading Django models through apps.get_model
Very minor thing here but wondering if anyone has ever encountered this. There are many instances where we have models from two apps that call each other, which causes circular dependency in Django (and python). The way around this to make use of apps.get_model. When I write a line that get's the model, I like to store the result in an upper case camel case format that mimics what the model would actually look like via a regular import, for example, like this: MyModel. Let's have this line: MyModel = apps.get_model('my_app', 'MyModel') This causes a yellow warning underline of the first MyModel in the line and says: Variable in function should be lowercase. Is there a good way around this? Should I be naming the variable differently? -
Join query sets but keep annotated fields with different values
The problem I'm trying to solve is to perform a search that involves multiple steps of relevance based on the initial query, e.g.: Search for "Michael Scott" Firstly, we try to match "Michael Scott" directly and save it to full_name This will probably return the most relevant objects Next, multiple queries will be run to search for each word separately like "Michael" and "Scott" and this will be set to words This will return lots of results, most being noise if it's a very common name In the end, the query sets are joined using full_name | words but this ends up mixing the results because of the model's ordering while what I wanted was to keep the everything in full_name before what's in words. To try to fix that, I annotated both query sets with a new value and tried to order by it after: full_name = full_name.annotate(relevance=Value(1, IntegerField())) words = words.annotate(relevance=Value(2, IntegerField())) return (full_name | words).order_by('relevance') What happens is that everything in words is changed to also have relevance=1 instead of keep the value of 2 I set before, rendering my ordering attempt useless... I know there are other ways to achieve the ordering I want, like converting … -

Django - Post data not in form.cleaned_data leading to key error
I have a dynamically created form build with Django. When this form is submitted i can see all the data in request.post, that being said when i access form.cleaned_data one of the inputs is not there. This is causing a KeyError when i try to access it. There are no errors caused by the form and the form is appearing valid. If anyone has any other avenues i could look, i would be very appreciative.

Applying css to Django generated form objects for textarea
The following screenshot shows the forms.py code for generating the textarea input box on the right hand side (which has placeholder text: "Your comment to the world"). The CSS however, is applied only to the pure html textarea box (to the left) and I cannot figure out how to get it to be applied to the Django generated textarea input box. You'll notice that the css has been automatically applied to the top 'Name' text input field. The styles.css code is here: body { background-color: white; } h1 { color: red; text-shadow: 3px 2px grey; font-family: Arial } p { color: black; font-family: Arial } input[type=text] { width: 20%; padding: 21px 20px; margin: 14px 0; box-sizing: border-box; font-size: 33; border: 2px solid red; border-radius: 4px; font-family: Arial } textarea[type=textarea] { width: 20%; padding: 21px 20px; margin: 14px 0; box-sizing: border-box; font-size: 33; border: 2px solid red; border-radius: 4px; font-family: Arial } forms.py (as shown above with the rendering of HTML) is below from django import forms class CommentForm(forms.Form): name = forms.CharField(max_length=20,widget=forms.TextInput(attrs={'placeholder':'Your Name Please'})) comment = forms.CharField(widget=forms.Textarea(attrs={'placeholder':'Your comment to the world'})) And finally, the sign.html page (with the html for the relevant page) is below {% load static %} <!DOCTYPE html> … -
How to filter objects using multiple-choice in many-to-many relations
In this simplified example, I have models named Movie and Genre, in many-to-many relationship. The template shows multiple-choice box where I can select multiple genres, which are returned to the view as an array, for example genres = ['Action', 'Comedy', 'Drama']. Now, I need to filter Movie object, which has exactly those three genres. I known that I can filter single choice with Movie.objects.filter(genre__name__exact = 'Action'). I known that I can use Movie.objects.filter(genre__name__in = ['Action', 'Comedy', 'Drama']), but that returns movies which have at least one of the genres from the array, I don't need that. What I need is a queryset of movies that has exactly ['Action', 'Comedy', 'Drama'], no more, no less. I also tried getting the genre queryset first: Genre.objects.filter(name__in = ['Action', 'Comedy', 'Drama']), and than using this queryset to filter Movie object, but I don't know if it's even possible. I had read the documentation on making queries, but didn't find the solution there. -

How to access multiple nested models in django?

GeoDjango inspectdb with multiple databases
I'm trying to run inspectdb on a PostgreSQL DB with Postgis. To generate the model for a postgresql view, I found here that I should use the command: python manage.py inspectdb --database my_schema my_view> my_view_legacy.py But because of PostGIS, inspectdb also tries to access a view in another schema, which raises the following error when it encounters a field of type geometry in my_view: django.db.utils.ProgrammingError: relation "geometry_columns" does not exist LINE 1: SELECT "coord_dimension", "srid", "type" FROM "geometry_colu...

Django channels 1.x how to authenticate user
I run a django server and am trying to create a channel for chatting. The client is a react-native application, with javascript backend. When the user connects to the server via websocket (or afterwards with a message, whatever is better), I want to be able to perform an authentication check, to see if the user is already in the database and get who this user is. I use default django auth accounts (django.contrib.auth.models). For authenticating the http requests I use django.contrib.auth.decorators.login_required and from the client I send an Authorization Header with the JWT token. How should I do the same for websocket requests? The recommended chat consumer uses channels.auth.channel_session_user_from_http. Is this the correct way for what I want? And how can I send the user's credentials (or token) from the client so that the server can check them? I saw a relevant SO question and the relevant documentation, but could not solve my problem. Any help would be appreciated. django version: 1.11.20 django-channels version: 1.1.8 -

Django,html template,for loop not working as expected
