Collectstatic seems to be working, but is not actually copying files to desired folder on Heroku
So I've been reading a lot of similar issues, but haven't found an exact match. I'm deploying my django production app in Heroku with uwsgi and whitenoise. So far I've set everything to its defaults. settings.py ... MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', ... ] ... STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static') ] ... uwsgi.ini [uwsgi] http-socket = :$(PORT) master = true env DJANGO_SETTINGS_MODULE=myProject.settings die-on-term = true processes = 4 module = myProject.wsgi:application memory-report = true ./manage.py collectstatic works locally and runs with debug mode set to false. The same command also works in heroku, hits me with 194 static files copied to '/app/staticfiles', 1 unmodified, 617 post-processed BUT the copied files do not show up in the corresponding folder when I tunnel to heroku with heroku ps:exec. Also when trying to connect to the website, ValueError is raised, as the files are not found. -

how can I use django to adjust the type in an input field
I try to create an automatic individual input mask with django and bootstrap. My goal is that I only need to change the forms.py and that the mask adapts itself. I know that django can create standard masks from forms.py, but unfortunately they are a bit ugly For example, I have the form class: class PersonForm(forms.ModelForm): m_firstname = forms.CharField(label='firstname ') m_lastname = forms.CharField(label='lastname ') m_email = forms.EmailField(label='email') m_birthday = forms.DateField(label='birthday ') class Meta: model = Person fields = ['m_firstname', 'm_lastname', 'm_birthday', 'm_email'] labels = { 'm_firstname': 'firstname', 'm_lastname': 'lastname', 'm_birthday': 'birthday', 'm_email': 'email'} and create the html code from it: {% for field in UserForm.visible_fields %} <div class="input-group mb-3"> <div class="input-group-prepend"> <span class="input-group-text">{{ field.label_tag }}</span> </div> <input type="text" class="form-control" aria-label="Default" aria-describedby="inputGroup-sizing-default" id={{ field.name }} name={{ field.name }}> </div> {% endfor %} that works very well, now i want to set the type of the input to date for the birthday. I need another handover: so I can write something like this: <input type={{ field.type }} class="form-control" aria-label="Default" aria-describedby="inputGroup-sizing-default" id={{ field.name }} name={{ field.name }}> unfortunately my approaches have not worked so far. I thought maybe to use the widgets and if necessary to query them with an if statement, but … -
Django process file before saving
I want to be able to process a file before saving in Django. I wanted to do it in a way that would affect both default Django (like through admin interface) and DRF (which uses the create method in the serializer). So I tried to overwrite the save method as below: class Soundbite(models.Model): app_label = 'soundbite' name = models.CharField('name', max_length=32, null=False) audio = models.FileField('audio', upload_to='soundbites', null=False, validators=[FileExtensionValidator(['mp3', 'wav', 'aac'])]) duration = models.FloatField('duration', null=False, blank=True)blank=True) def save(self, *args, **kwargs): if not self.duration: storage: FileSystemStorage = self.audio.storage file = self.audio # process file, like get duration using ffmpeg and validate its a proper audio file. info = probe(storage.path(self.audio.name)) duration = info['format']['duration'] print(duration) self.duration = duration super().save(*args, **kwargs) # Call the "real" save() method. But I don't exactly know how to access the file before calling the super save method. I can do it either by having a filesystem path with the file, or by reading the raw bytes of the file. How would I access the file before saving to database? -
Create a new table in the view.py in Django
In the document, I can define a table in the models.py. from django.db import models class Person(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) Run python manage.py makemigrations and python manage.py migrate to create a new table in the database.

How to store GDAL objects in a geodjango Geometry object?

why the guniron.sock file is not getting created at all and throwing error?
First of all, I have seen tons of documents in stackoverflow as well as other blogs. But nothing seems to be working for me. I have hosted a django based web application. I have followed the link django deployment, I have applied almost everything that is mentioned in the document, everything was going fine until I came to the point where I had to configure gunicorn. I a not working in the python virtual environment. However, almost every solution across the various platform only talks about gunicorn configuration in virtual environment.

Django passing parameters to url tag according to user input
I have the following href in my template: <a onclick="location.href='{% url 'doctormonthbilling' %}{% urlparams month=monatAMA doctor=arztAMA %}?' "></a> and this url pattern: path('doctormonthbilling/<str:month>/<str:doctorid>', views.doctormonthbilling, name='doctormonthbilling'), Basically monthAMA and arztAMA are 2 dropdown lists where the user chooses a month and a doctor from the list. I want to add the selected values to the url. i was hoping i can "simply" add them like so: {% url 'doctormonthbilling' month=monatAMA & doctor=arztAMA %} but it doesn't work. So i went through some stackoverflow questions and saw a self defined tag. So i implemented it as follows: @register.simple_tag def urlparams(*_, **kwargs): safe_args = {k: v for k, v in kwargs.items() if v is not None} if safe_args: return '?{}'.format(urlencode(safe_args)) return '' and i get the following error: Reverse for 'doctormonthbilling' with no arguments not found. 1 pattern(s) tried: ['doctormonthbilling/(?P[^/]+)/(?P[^/]+)$'] How can i get the values from the selected fields and add them to the url? Thanks!
