How to close a popup when another popup is open using JavaScript?
I'm working on a Python/Django web application, and I don't have much knowledge of JavaScript yet. The answers I've googled suggest a bit of a different approach, and I can't adjust those solutions to my code due to my yet little knowledge of JS. Will be grateful for helping me out. Thanks in advance! So, I have a few popup windows, which have different IDs and they're all opened and closed with the same two JavaScript functions by passing thir IDs as a $target variable. I also want to close any opened popup window if another popup is opened by the user, so only one can be opened at the same time, and also close a popup window if the user clicks a glyphicon button (the same that opened that popup window with the first click). Here's my code: html template <script> function popup($target) { document.getElementById($target).style.display = "block"; } function closepopup($target) { document.getElementById($target).style.display = "none"; } </script> Example of where these functions are called (same template): <a class="btn btn-default" onclick="popup('add')" style="position: absolute; right: 2%; bottom: 10%; padding: 6px;"><span class="glyphicon glyphicon-pencil"></span></a> <div class="form-popup popupfont" id="add-important"> <form action="{% url 'add-general' %}" method="post" class="form-container"> {% csrf_token %} <label for="task_text">Add a task:</label> <input type="text" … -

Django get random objects from database
I have a database with a million+ columns and I want to return a 100 random objects from that database. After searching the web for a solution I saw that there is a big argument about the order_by['?'] approach and it's alternatives(Even in the Django official documentation!), In addition, most of the discussions about this issue are from 2010+-. So, I'm wondering what is the best practice to generate random objects from my Djando model. I saw in the Django documentation that it might based on the database itself, so is it matter if it MySQL or PostgreSQL or something else? or if it depends on the backend itself (AWS RDS or their competitors) Here's my model: class BasicPost(models.Model): author = models.ForeignKey('auth.User', on_delete=models.CASCADE) published = models.BooleanField(default=False) created_date = models.DateTimeField(auto_now_add=True) title = models.CharField(max_length=100, blank=False) body = models.TextField(max_length=999) media = models.ImageField(blank=True) def get_absolute_url(self): return reverse('basic_post', args=[str(self.pk)]) def __str__(self): return self.title Thanks! -
django-tenant and django resframework testing
I'm trying to switch to test driven development. But for that I need to understand unit test :) I got the following problem. I'm using Django rest framework and django-tenants in combination. So far so good. However to test anything you need to make a tenant. class Test1(TenantTestCase): def setUp(self): super().setUp() self.client = TenantClient(self.tenant) Once you do so your tenant is setup. But if I was to test the API the client is the TenantClient and not the APIClient. The testcase is TenantTestCase. So my question. How do you combine the two? -

How to optimize deep nested foreignKeys in Django queryset
TLDR; Is there a better way to handle deep nesting in this Django queryset?

Django Form Can't Filter Foreign Key on Dropdown
I have a "CustomUser" class that I got from an all-auth tutorial (Django All-Auth Tutorial) and I have user as a foreign key in each model, which works as intended, only showing records pertaining to the current logged in user to that specific user. For example: class Education(models.Model): user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) EducationInstitutionName = models.CharField(verbose_name=_('Institution Name'), max_length=100, default=None) EducationLevel = models.CharField(verbose_name=_('Education Level'), choices=EDUCATIONLEVEL, max_length=100, default=None) EducationStartDate = models.DateField(verbose_name=_('Education Start Date'), default=None) EducationEndDate = models.DateField(verbose_name=_('Education End Date'), default=None) EducationCaoCode = models.CharField(choices=CAO_CODE, max_length=100, default=None) EducationDesc = models.CharField(verbose_name=_('Education Description'), max_length=250, default=None) def __str__(self): return self.EducationInstitutionName This works perfectly and I am achieving what is needed. The issue arises when I have a table comprised of Foreign Keys which is the focal point of my application which takes the constituent parts of a CV and allows you to combine them to make a CV of interchangable sections. class Cv(models.Model): user = models.ForeignKey( CustomUser, on_delete=models.CASCADE, ) CvName = models.CharField(verbose_name=_('CvName'), max_length=100, default=None) CvEducation = models.ForeignKey(Education, on_delete=models.CASCADE) CvSkills = models.ForeignKey(Skills, on_delete=models.CASCADE) CvWorkExperience = models.ForeignKey(WorkExperience, on_delete=models.CASCADE) def __str__(self): return self.CvName This gives me... enter image description here Dropdown showing all users "Education" I've tried to filter this with init parameters but this breaks the "save" function.

Making a Django proxy for websocket (jupyter lab)
I'm having a problem with an application I'm trying to mount, I need to have a JupyterLab and notebook iframed in the django app, but I needed to proxy it through the Django app so I can use the Django authorization and authentication to access the notebooks, I used django-revproxy to proxy all the http routes to the Jupyter endpoint, and it works pretty easy, but I can't make the kernel of the Jupyter notebook to work, b/c it works through web sockets, I tried to use Django Channels and ProtocolTypeRouter/URLRouter to proxy the websockets routes, but I'm getting this error, "failed: Error during WebSocket handshake: 'Upgrade' header is missing", now I'm not sure if my approach of proxy the JupyterLab endpoints is the best, I got to a wall and I feel trap and don't know how to solve this problem, what do you recommend to handle this? thank you.
