How to get your own Pytesseract font in Heroku project?
I have a Vue, Django integrated project. I hosted the Vue project on Netlify and the Django project on Heroku. A python script (integrated into Heroku) is called on certain buttons which extract data and posts this to the Django API to be viewed on the frontend. Now in my normal project I have made a font type within Pytesseract to extract data correctly. How do I integrate this font type into Heroku? I'm trying to get Heroku to use my font (my .traineddata file). So I have it in my local tessdata folder (the traineddata file, in the same directory as the normal 'eng' data file), but don't know how to get it on Heroku. Thanks! -

gunicorn prevent HUP after it has been triggered
Based on Gunicorn's documentation there is no hook for pre_worker_exit. What I am basically trying to achieve is to prevent workers from exiting if some criteria are met. In my Django application, I have some functions that due to race condition, they are being initiated after the HUP signal and therefore once the workers exit and new ones are spawned, the functions get interrupted in the old workers. Is there a way to stop the HUP signal after it has been triggered or have some kind of pre_worker_exit hook that will check if some criteria are met and therefore delay the worker exiting? Thanks -

Adding additional information into each form field
I am using Django/Wagtail and the wagtailstreamforms package to build forms. Unfortunately you cannot add two fields side-by-side in the wagtailstreamforms form builder out of the box, so I am trying to add a functionality that allows the user to input an integer 1 to 12 (based on Bootstrap columns - col-1 to col-12) for each field and this number will be retrieved in the templates and will be used. In the wagtailstreamforms_fields.py file, I've started to override the CharField model to add the extra width integer: from django import forms from wagtailstreamforms.fields import BaseField, register from wagtail.core import blocks class CustomCharField(forms.CharField): def __init__(self,*args, **kwargs): self.width = kwargs.pop('width') super().__init__(*args,**kwargs) @register('singleline') class Column_SingleLineTextField(BaseField): field_class = CustomCharField def get_options(self, block_value): options = super().get_options(block_value) options.update({'width': block_value.get('width')}) return options def get_formfield(self, block_value): options = super().get_formfield(block_value) return options def get_form_block(self): return blocks.StructBlock([ ('label', blocks.CharBlock()), ('help_text', blocks.CharBlock(required=False)), ('required', blocks.BooleanBlock(required=False)), ('default_value', blocks.CharBlock(required=False)), ('width', blocks.IntegerBlock(help_text="Width of field, 1 to 12, 12 is full width.", max_value=12, min_value=1, default=12, required=True)), ], icon=self.icon, label=self.label) This code adds the extra integer input for the singleline field in the wagtailstreamforms form builder page in Wagtail settings. Now the issue I'm facing is, I'm not able to retrieve the width parameter in the templates. … -

I have created a 'Post' model in my django app that uploads a basic article to the database.

I am trying to save the history of an object by using django-simply-history library, so far i can see the changes of the object itself but not the user that made the changes. I have the following set up. Settings: # settings.py INSTALLED_APPS = [ # ... 'simple_history', # ... ] MIDDLEWARE = [ # ... 'simple_history.middleware.HistoryRequestMiddleware', # ... ] Models: from django.db import models from apps.companies.models import Company from simple_history.models import HistoricalRecords # Create your models here. class Customer(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=20) dateCreated = models.DateTimeField(auto_now_add=True,) dateUpdated = models.DateTimeField(auto_now=True,) telephone = models.CharField(max_length=20, blank=True, null=True) address = models.CharField(max_length=20, blank=True, null=True) email = models.EmailField(max_length=254, blank=True, null=True) history = HistoricalRecords() Then in the Shell i do: customer = Customer.objects.all().last() customer.name = "Test" customer.save() customer.history.all().last() Out[79]: <HistoricalCustomer: Customer object (d2211cc1-9762-4f6d-9086-634deee95b1e) as of 2021-08-24 09:28:44.978543+00:00> # How can I print the user that changed the object???? customer.history.all().last()_history_user Thanks, -
Change model in CreateView dependending on user in django
I want to change the model of a createview dependending on the user. The view class is as follow: class SubirCasoView(LoginRequiredMixin, CreateView): login_url = reverse_lazy('users_app:user-login') template_name = 'casos/crear-caso.html' success_url = reverse_lazy('casos_app:update-caso') def get_form_class(self): current_user = self.request.user if current_user.especialidad == 'Reumatología': self.form_class = CasoReumaForm else: self.form_class = CasoDermaForm return self.form_class def form_valid(self, form): """If the form is valid, save the associated model.""" if 'borrador' == self.request.POST: publicar = False self.object = form.save() self.object.user = self.request.user '''for each in self.cleaned_data['images_description']: ImageDescriptionDerma.objects.create(file=each, caso=self.object) for each in self.cleaned_data['images_evolucion']: ImageEvolucionDerma.objects.create(file=each, caso=self.object)''' else: publicar = True self.object = form.save() self.object.user = self.request.user '''for each in self.cleaned_data['images_description']: ImageDescriptionDerma.objects.create(file=each, caso=self.object) for each in self.cleaned_data['images_evolucion']: ImageEvolucionDerma.objects.create(file=each, caso=self.object)''' return super().form_valid(form) What I was trying to do is something similar to the function 'get_form_class' but with model. I have try it with 'get_object' function but seems not to work. My idea is to do something like: def function_name(self): current_user = self.request.user if current_user.especialidad == 'Reumatología': self.model = CasoReuma else: self.model = CasoDerma return self.model -
id field which is not primary key in django django model
Is it possible to create an id field in a model that is not primary_key in django? If so, how to do it? To be clearer, here is my model: class GWS(models.Model): id = models.CharField(max_length=20,primary_key=False) ... What can I do to prevent the id field from being primary key? api.GWS: (models.E004) 'id' can only be used as a field name if the field also sets 'primary_key=True'
