How to create a custom filter search bar in django?
I am trying to create a filter search bar that I can customize. For example, here is a view: class StudentListView(FilterView): template_name = "leads/student_list.html" context_object_name = "leads" filterset_class = StudentFilter def get_queryset(self): return Lead.objects.all() and here is my filters.py: class StudentFilter(django_filters.FilterSet): class Meta: model = Lead fields = { 'first_name': ['icontains'], 'email': ['exact'], } Until now, I can only create a filter search bar that can provide a list of instances that match first_name or email(which are fields in the Lead model). However, this does now allow me to do more complicated tasks. Lets say I added time to the filter fields, and I would like to not only filter the Lead model with the time value I submitted, but also other Lead instances that have a time value that is near the one I submitted. Basically, I want something like the def form_valid() used in the views where I can query, calculate, and even alter the values submitted. Moreover, if possible, I would like to create a filter field that is not necessarily an actual field in a model. Then, I would like to use the submitted value to do some calculations as I filter for the list of … -

Restrict Integer value in the django urls
I have following django url, which allows users to register for any one security code from 1 to 6. path('add/<int:security_code>/', security_views.RegisterView.as_view(), name='register_code'), Url should render the template up to 6 security codes such as https://www.example.com/add/1/ #-- It shoould work https://www.example.com/add/2/ #-- It shoould work https://www.example.com/add/3/ #-- It shoould work https://www.example.com/add/4/ #-- It shoould work https://www.example.com/add/5/ #-- It shoould work https://www.example.com/add/6/ #-- It shoould work https://www.example.com/add/7/ #-- It should throw 404 when user types a number greater that 6. What change I would need to do to restrict url for limited codes, it should throw 404 or bad request error if user manually puts a differrent number. I dont want to modify the view as I would need to add Get as well as Post method. from django.views import generic from core import models class RegisterView(generic.edit.CreateView): model = models.SecurityCode fields = ['name', 'code'] Is there any way we can do it without modifying views part -
How to use trained font in Pytesseract?
I have made a font type within Pytesseract to extract data correctly. How do I integrate this font type into my Heroku project? I'm trying to get Heroku to use my font (my .traineddata file). In my Python script, (how) would it be possible to call the local directory for the font.traineddata file to use it as a 'lang' in the pytesseract functions, without having it in the tessdata folder? (As i have to use the Heroku TESSDATA_PREFIX folder, which I think I cannot add the font.traineddata file to). Thanks! -
How to locate user location to map through ip address in python folium?
I am using Django REST Framework. Now I can Access User IP from the request of user using django-ipware. from ipware import get_client_ip def getlocation(request): client_ip, is_routable = get_client_ip(request) It provides me the IP address of the request from where user is accessing.

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.

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. … -
