How to choose child model while create parent?
Is there a way to choose child model as type of parent model in a parent creation form? Some code for example: from django.db import models class Parent(models.Model): title = models.CharField( max_length=100 ) some_attribute = models.PositiveIntegerField( null=True, blank=True, ) class ThinChild(Parent): name = models.CharField( max_length=300, ) class ThickChild(Parent): platform = models.CharField( max_length=300, ) Let's say i want to be able to create both of ThinChild and ThickChild from one form. Is it possible to do this, for example, by creating an instance of the Parent model and selecting the required child from the list of child models (let's name that field "child type"), so that depending on the choice a form appears with a fields set corresponding to the selected model? -

Obtaining set within template using template tags
I've got a model of Review and a model of Answer. Multiple answers are related to each review by way of a foreign key as per below. Let's assume that I have 5 instances of the Review model and for each instance, there are 3 instances of a related Answer model.

How to dynamically pass arguments to forms in django?
I have a form 'BasicSearch', having two fields. One is a choice field called 'search_by' while the other is a text field called 'search_for'. I have models for customers, suppliers, items, projects and few others. What I want to do is to give user the ability to perform their searches on various models on their respective pages by providing their query in the text field and selecting from the choice field what they want to search in (the column headers from the models) I have already tried several solutions on stackoverflow but none is working for me. It works fine when I manually create a dictionary of column headers and pass it to the choice field. Currently the search form class looks like below (Which is not working) class BasicSearch(forms.Form): def __init__(self,arg): super(BasicSearch, self).__init__(arg) caller = arg if caller == 'customer': cu = Customers() field_dct = get_col_heads(cu) self.fields['search_by'] = forms.ChoiceField(choices=field_dct,widget=forms.Select(attrs={'class':'form-control'})) self.fields['search_for'] = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control'})) The get_col_heads function: def get_col_heads(cu): all_fields = cu._meta.fields all_field_list = [] for fields in all_fields: column_head = (str(fields)).split(".") all_field_list.append(column_head[-1]) field_list = all_field_list[1:-2] field_dct = tuple(zip(field_list,field_list)) return field_dct customers view class in view.py class IndexView(TemplateView): template_name = 'crudbasic/index.html' def get_context_data(self,**kwargs): context = super().get_context_data(**kwargs) context ['page_title'] = '' return … -

Model Form not displaying
I am using modelform for a model department is not working. (BTW,I have a custom user model also in users app of same project). All I am getting is a 'Test up' button in the html output. Also, Change E-mail and Signout are displaying may be consequence to usage of allauth in middleware.

Having trouble getting django heroku to run properly. How do I resolve error code=H14 desc="No web processes running"?
I have previously ran this app on Heroku without issues. But it had been around 6 months since I deployed and I also switched computers from a Linux to a Windows machine. Now when I deploy, the deployment is successful but the service does not work. When I check the logs the error is: code=H14 desc="No web processes running" I have not changed the Procfile or the requirements.txt since it had been working requirements.txt: django gunicorn django-heroku requests djangorestframework django-cors-headers flask-sslify Procfile: release: python manage.py migrate web: gunicorn findtheirgifts.wsgi --log-file - wsgi.py """ WSGI config for findtheirgifts project. It exposes the WSGI callable as a module-level variable named ``application``. For more information on this file, see https://docs.djangoproject.com/en/2.0/howto/deployment/wsgi/ """ import os from django.core.wsgi import get_wsgi_application os.environ.setdefault("DJANGO_SETTINGS_MODULE", "findtheirgifts.settings") application = get_wsgi_application() I have tried some suggestions from similar threads heroku ps:restart heroku buildpacks:clear heroku ps:scale web=1 None of which seemed to change anything. Any help on this would be greatly appreciated!
