Why my js function works inside of script tag and why not in an external java script file django forms
I have a form that displays plain text when component is checked, in django like below class CompanySearchForm(forms.Form): check = forms.BooleanField() def __init__(self, *args, **kwargs): super(CompanySearchForm, self).__init__(*args, **kwargs) self.fields['check'].widget.attrs.update({"onclick": 'show_p()', 'id': 'check'}) And i have also my js file with the following function function show_p() { var checkBox = document.getElementById("check"); var texto = document.getElementById("text"); if (checkBox.checked == true){ texto.style.display = "block"; } else { texto.style.display = "none"; } } My template: {% extends 'base.html' %} {% load static %} {% block extra_styles %} <script href="{% static 'js/ajax_ubigeo.js' %}"></script> {% endblock %} {% block content %} <form action="" method="post"> {% csrf_token %} {{ form.check }} </form> <p id="text" style="display: none">hola</p> {% endblock %} My question is why show_p() works inside of script tag and inside the template. But why not in an external java script file ? -
Django allauth - custom email verification url does nothing
I created a custom email verification url so that the user can be redirected to my react frontend before a get request will be sent. However, on sending the get request, a 200 status code is sent back but no email verification takes place. The url sent looks like this: http://localhost:8000/verify-email/Mw:1joams:KRlaiGKPx7fhQ6fHVYRtxvYo_v4/ and I am not sure if that key looks right. My codes look like these: #Adapter.py from allauth.account.adapter import DefaultAccountAdapter from django.conf import settings class DefaultAccountAdapterCustom(DefaultAccountAdapter): def send_mail(self, template_prefix, email, context): context['activate_url'] = settings.URL_FRONT + \ 'verify-email/' + context['key'] msg = self.render_mail(template_prefix, email, context) msg.send() #Urls.py from allauth.account.views import confirm_email url(r'^verify-email/(?P<key>\w+)/$', confirm_email, name="account_confirm_email"), ACCOUNT_ADAPTER = 'users.adapter.DefaultAccountAdapterCustom' Please can someone tell me what I am doing wrong? -
How to render information from a ForeignKey field through DetailView class?
I have two models (Taxonomia and Distribucion) which are the following: # models.py file class Taxonomia(models.Model): id_cactacea = models.AutoField(primary_key=True) subfamilia = models.CharField(max_length=200) class Distribucion(models.Model): id_distribucion = models.AutoField(primary_key=True) localidad = models.TextField(null=True, blank=True) taxonomia = models.ForeignKey(Taxonomia, on_delete=models.CASCADE, default=1) As you can see in Distribucion there is a one to many relationship with the Taxomia table. Implement the two models in the "admin.py" file so that you can edit the Distribucion table from Taxonomia class DistribucionInline(admin.TabularInline): model = Distribucion extra = 0 class TaxonomiaAdmin(admin.ModelAdmin): actions = None # desactivando accion de 'eliminar' list_per_page = 20 search_fields = ('genero',) radio_fields = {"estado_conservacion": admin.HORIZONTAL} inlines = [DistribucionInline] admin.site.register(Taxonomia, TaxonomiaAdmin) In turn, the file "view.py" renders the Taxonomia table as follows: from repositorio.models import Taxonomia, Distribucion class CactaceaDetail(DetailView): model = Taxonomia template_name = 'repositorio/cactacea_detail.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['distribuciones'] = Distribucion.objects.all() return context I tried to access to context ['distribuciones'] information from the template as follows without getting any results: {% for obj in object.distribuciones %} {{ obj.localidad }} {% endfor %} OBS: For each Taxonomia element there will be four elements from the Distribucion table, so I need to use a FOR loop Is the way I add the information from the Taxonomia … -

How do I properly output a string for a YAML file that includes a "#"?
I'm using Django 3 and Python 3.7. I'm trying to write a function that will output properly formatted YAML. I have this ... def strip_invalid(s): res = '' for x in s: if Reader.NON_PRINTABLE.match(x): # res += '\\x{:x}'.format(ord(x)) continue res += x return res ... yaml_street = load(strip_invalid(street.strip().encode("utf-8", 'ignore').decode("utf-8"))) The problem is, if "street" is "55 E JACKSON BLVD # 150" the above outputs 55 E JACKSON BLVD Note that everything after and including the "#" was removed. How can I adjust the above so that everything is included but perhaps escaped properly for YAML output? -

I need to display a form to user enter the quantity for each product (previously registered). For example... Product A: Quantity A Product B: Quantity B Product C: Quantity C I've already create a ProductModel: class ProductModel(models.Model): name = models.CharField(null=False, blank=False, max_length=20) code = models.CharField(null=False, blank=False, max_length=20) And I'm trying to set a model to the Order, like this one: class OrderDetailModel(models.Model): product = models.ForeignKey(ProductModel, on_delete=models.CASCADE) But how can I speccify the quantity related to a specific product?

I get a list in my form to choose the product and insert an unique quantity. Is there any way accomplish this? I'm using this Form: class QuantitiesForm(forms.ModelForm): class Meta: model = OrderDetailModel fields = ("product", "quantity") -

How do I reload Django Webapp code using gunicorn?
I've updated my Django webapp running on a Digital Ocean server and it keeps showing my old code. Is something being cached? I've tried everything to reload the code and nothing is working. Things I've tried: pkill gunicorn sudo systemctl daemon-reload sudo systemctl restart gunicorn kill -HUP masterpid kill -9 masterpid sudo systemctl restart nginx Literally nothing works. Has anyone else had this issue? I'm running my web browser in debug mode with caching disabled so it's not a browser issue. -
Efficiency of using JSONFields vs. Pure SQL approach Django Postgres
I am wondering what is the difference in efficiency using JSONFields vs. a pure SQL approach in my Postgres DB.

Is there a way to automate creation of pages(and slugs) as and when a record is created in Django
