Django ForeignKey default value in new table
I need to set a default value to a ForeignKey after the model has been migrated. Is this possible? For instance, a "meal" Class has a ForeignKey named "drinks". Some drinks are added, Pepsi, Coke,.. to the drink table. In the meal Class is it possible to name Coke as the default? From the docs I see only that the index can be used. That implies that I would have to ensure that I added the correctly named default into the correct index. Then I would be stuck with it hard coded in. How is it done so that changes to the default can be done after the fact? An example would be great if anyone has one handy. Best regards. -

Why django template loader is case-sensitive in production but not in development
I'm using manage.py runserver on a MacOs Catalina OS as development. I have some templates that fit my built-in class based views. For example: CuadroDeControl_detail.html LoteDeMedio_list.html TipoDeMedio_detail_tablaCuadros.html CuadroDeControl_detail_resumen.html LoteDeMedio_list_tabla.html TipoDeMedio_list.html CuadroDeControl_detail_tablaMetodos.html MetodoDeControl_detail.html TipoDeMedio_list_tabla.html LoteDeMedio_confirm_delete.html MetodoDeControl_detail_resumen.html dropdown_CuadroDeControl.html LoteDeMedio_create.html TipoDeMedio_confirm_delete.html dropwdown_CuadroDeControl.html LoteDeMedio_detail.html TipoDeMedio_detail.html LoteDeMedio_detail_resumen.html TipoDeMedio_detail_resumen.html Here is an example of a working view: 58 class TipoDeMedioDetailView(AreaCalidadMixin, DashboardMixin, DetailView): 59 model = TipoDeMedio Note that my views do not explicitly set template_name. On my production environment, all my views load just fine.Django's template loader knows that the corresponding template to the view is TipoDeMedio_detail.html However, on my production environment, which is set up with apache2 and mod_wsgi on a Ubuntu 20.04.2 LTS x86_64 Linode VM, the template loader fails to load the template of the same view, because it searches for it in all lowercase. Here is an example: Request Method: GET Request URL: http://45.79.4.38/calidad/TipoDeMedio/lista Django Version: 3.1.6 Exception Type: TemplateDoesNotExist Exception Value: calidad/tipodemedio_list.html Exception Location: /home/jonatan/django-rodam/venv/lib/python3.8/site-packages/django/template/loader.py, line 47, in select_template Python Executable: /home/jonatan/django-rodam/venv/bin/python Python Version: 3.8.5 Python Path: ['/home/jonatan/django-rodam/mysite', '/usr/lib/python38.zip', '/usr/lib/python3.8', '/usr/lib/python3.8/lib-dynload', '/home/jonatan/django-rodam/venv/lib/python3.8/site-packages'] Server time: Mon, 21 Jun 2021 18:24:19 -0500 Template-loader postmortem Django tried loading these templates, in this order: Using engine django: django.template.loaders.filesystem.Loader: /home/jonatan/django-rodam/mysite/templates/calidad/tipodemedio_list.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/jonatan/django-rodam/mysite/login/templates/calidad/tipodemedio_list.html … -
How to get a variable in another js file in django?
I am trying to use moovit embebed services. I want to put an origin and destination address automatically. So, I have this function in a js file that receives the origin address and open a new window. I don't know how to get this data from js in html. function print_moovitmap(origin) { origin_ad = origin; //Origin_ad is global window.open('/new', '_blank'); } I am working with django. I have also origin_ad in a form field with an id but I couldn't access to this form field in html. It gives me null. origin_address=forms.CharField(max_length=200,widget=forms.TextInput(attrs={'class':'data_aux data','id':'origin_address'})) In html (null): console.log(document.getElementById('origin_address')); And in new.html: <div class="mv-wtp" id="mapa_moovit" data-to='' data-lang="es"> <script> var m = document.getElementById('mapa_moovit'); m.setAttribute("data-to", "Central Park"); m.setAttribute("data-from", "Times Sq"); </script> {% load static %} <script src="{% static 'moovit_script.js'%}"></script> </div> I need to set atribute data-from to origin_ad but I don't know how.

How to do aritmethic operations with django queries and .count?
I want to get a value by using the amount of objects I have in my database and making operations over that and then displaying the result in the template (So I'm passing this value in the context). The answers I found was about making operations with model fields, and that doesn't help me. This is what I tried to do in the view. (status is a charfield with options, but it could be anything) def get_context_data(self, **kwargs): context = super(Index, self).get_context_data(**kwargs) amount_one = mymodel.objects.filter(status='status1').count amount_two = mymodel.objects.filter(status='status2').count total_amount = amount_one + amount_two result_amount = (amount_one * 100) // total_amount context['result'] = result_amount return context This doesn't work, but you could get the idea of what I'm trying to do. -
Geo redirect same domain after slash with AWS
Lets say i have a website called abc.com, I'm planning on scale the website based on geo location, I have two ways in mind. The first way: paris.abc.com, london.abc.com The second way: abc.com/paris, abc.com/london The first way seems simpler with AWS, The idea being hosting different subdomains to different instances with different databases, Each subdomain is basically a completely different website. But I prefer the second way, What i have in mind is, Setting up geo redirect to different instances but to the same domain, "abc.com", Then have instance A redirect abc.com to abc.com/paris inside my django project, Have instance B do the same thing to abc.com/london. Now if i do it this way, What would happen if someone from london, Instead of typing the url abc.com, They typed abc.com/paris? Would they be able to access the paris page via instance A? (This is what i want, I want them to have acess) Or the page will be empty since the django project inside instances B(london) have no page called paris. Assuming both ways are achievable, If someone logged in paris.abc.com or abc.com/paris, How do u keep them logged in If they go to page london.abc.com or abc.com/london, A shared … -
Nothing renders on Django Template
building a news aggregator. I am collecting reddit and twitter posts using their APIs, and then I create a model object for each post, which is stored in my database. I'm then passing in these post objects as context into my template, looping through the context in the template with the hope to display the posts 'html' attribute (A model field I created) onto the page, which in turn embeds the post onto the screen. However, I can't figure out why my template page is still blank. No errors are thrown, and the model objects are being created because I can see them in the admin panel. I'll provide my models.py, views.py, and template to be taken a glance at. I appreciate and am grateful for any help/advice. models.py class Post(models.Model): post_type = models.CharField( max_length=20, null=True, blank=True) root_url = models.CharField(max_length=200, default="") html = models.TextField(default="") created_at = models.DateTimeField(auto_now_add=True) views.py def main(request): all_posts = Post.objects.all context = {'posts': all_posts} return render(request, "test.html", context) template {% block content %} {% autoescape off %} <div class="container"> <div class="row"> <div class="col-6"> <h3 class='text-center'>Twitter News</h3> {% for post in posts %} {% if post.post_type == 'twitter' %} <div class="mdl-card__media" id="timeline"></div> {{ post.html }} {% endif %} … -

Add label or modifying widget on django-filter form
I'm looking for a way of specifying what the select fields in the filter form are for, this is how it looks like right now: And is hard to understand what the select inputs are for, the ideal would be to change the default option ("Unkown" and "--------") but it should be custom for each one. Already tried that but couldn't find a way to do it, it is possible? If someone knows a way of doing this it would be great. Adding a label should be the easier way, but don't know how to do it. filters.py class PatientFilter(django_filters.FilterSet): class Meta: model = Patient fields = { 'dni': ['exact'], 'first_name': ['icontains'], 'last_name': ['icontains'], 'risk': ['exact'], 'status': ['exact'], 'ubication': ['exact'], 'supervisor': ['exact'], } HTML {% if filter %} <form action="" method="get" class="form form-inline"> {% bootstrap_form filter.form layout='inline' field_class="mr-3 mt-3" %} <div class="mt-3"> {% bootstrap_button 'Filter' button_class="btn-secondary" %} <a href="{% url 'patients' %}" class="ml-3 btn btn-secondary">Clear</a> </div> </form> {% endif %} The select inputs are foreign keys, here is its definition in models.py status = models.CharField(max_length=15, choices=STATUS_CHOICES) ubication = models.ForeignKey(Ubication, on_delete=models.CASCADE) supervisor = models.ForeignKey(User, on_delete=models.SET_NULL, null=True) I'm using tables2 with django-filters. -
How to display content assigned to foreignkey DJango

Dynamic Fields On A Serializer For A ForeignKey
I set up a serializer that is able to dynamically serialize the desired fields as specified in the Django Rest Framework docs. class DynamicFieldsModelSerializer(serializers.ModelSerializer): """ A ModelSerializer that takes an additional `fields` argument that controls which fields should be displayed.

Django admin model query url string on NOT EQUALS
I have a simple Django ForeignKey relationship between two models in postgreSQL. The logic here is the Sample object can optionally have a foreign key into a type of sample control. from django.contrib.postgres.fields import CICharField from django.db import models class Sample(models.Model): controls_applied = models.ForeignKey(SampleControl, null=True, blank=True, on_delete=models.SET_NULL) class SampleControl(models.Model): id = CICharField(max_length=200, primary_key=True) On the admin changelist for Sample, I am trying to create filter that queries all or none of Samples that have a specific control (in this case, we'll use a SampleControl with id='runcontrol'). I'm trying to craft the specific URI string to append to my changelist url as I have other filters I'm trying to run in conjunction. To get all samples with controls_applied= 'runcontrol', I can simply append the following string to my URL (notice the reference to the id of the foreign key): ?controls_applied__id=runcontrol But if I want to get all samples that are not run control, it's more complicated. Wasn't sure what to do, so I decided to use 'startswith', which has a convenient 'notstartswith' companion that will do the inverse. When I use this, I see that the following works: ?controls_applied__id__startswith=runcontrol However, the inverse ?controls_applied__id__notstartswith=runcontrol gives me an error: Unsupported lookup 'notstartswith' for … -

Almost everything seems to be well, except that I'm getting this error when posting (authenticated user) or confirming (anonymous user) comments: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'ORDER BY django_comments_xtd_xtdcomment.thread_id ASC, `django_comments_x...' at line 1") Any advice on how to resolve it? I'm using MySQL 8.0, but I've also tested with 5.6 and still get the same error.
