问题 I have used as many examples online as I could cobble together in an attempt to get my two simple models to have the ability to do an inline formset allowing me to add many files to a technial drawing. This is not working, I can only add one file for the Create and the update only updates the Technical_Entry model, not a file...which in of itself acts funny. The UI ona create shows one spot to add a file, then save the entire record and its child record. That works. The update, the UI shows

问题 I have two models, field of one of them pointing to the other as shown below: class Group(models.Model): group_company_id = models.CharField(primary_key=True, ...) class Company(models.Model): company_id = models.CharField(primary_key=True, ...) group_company = models.ForeignKey(Group, related_name="related_grp_company", ...) I am trying to get all the Companies that have been created for a particular Group . So I am trying to get the company_id (and other) values in Djnago UpdateView as a

问题 I have a very simple Class Based View: In views.py: class IncidentEdit(UpdateView): model=Incident fields = visible_field_list sucess_url = '/status' works fine as-is. I have associated CreateView , DeleteView , etc. I can create edit and delete records. Now to fine-tune the project, I need to add field validation. My question : Where do I put basic validation code when I have based the view on the 'model=' rather than 'form=' ? I could change everything to use form based views, but the whole

问题 I'm trying to filter a list of objects in my database but I can't get it to work on the template using _set.all . The strange thing is it's something I've done in two other places in my project but I cant see why it isnt working this time. view.py: class GolfMonthlyView(generic.ListView): template_name="monthly_view/golf-monthly-view.html" context_object_name='golf_monthly_view' queryset = GolfMonthlyView.objects.all() def get_context_data(self, **kwargs): context = super(GolfMonthlyView,

问题 Using users as an example I am trying to show how many users there are. get_context_data works totally fine but get_queryset does not. I know that it's not set up properly but I've been playing around with it for quite some days and something is just not clicking.. The main goal is to use the Dajngo-Filter form and then be able to get the updated number of user count. I've only found endless documentation on how to show the "list" of users. Which I have done but no documentation on how to

问题 I have cbt generic listview I want filtering with two slugs. But slug_url_kwargs only allows to pass single string. How can i update slug_url_kwarg to support multiple slugs? Or what can i do else? So i have this models and view function class SaityProfile(models.Model): user = models.ForeignKey(User, default=0) about = models.CharField(max_length=255, blank=True) name = models.CharField(max_length=255) url = models.CharField(max_length=255, unique=True) def __unicode__(self): return self

问题 I have two questions in regards to the problem I am currently facing: Is it best practice in django to overwrite the post method in the CreateView? If it isn't do you write a form _valid function on the CategoryFullForm or in the CreateView and how would it look? The CreateView currently works great, but want to make sure there isn't a better way to do this. If this is best practice, how would you override the get function in the UpdateView so you would be able to edit the files that relate

问题 I am building a frontend form that allows someone to post an article without accessing the admin. When the user is logged in, I would like for him/her to be able to write an article. Upon saving, I would like that user to automatically be set as the author of the article. I am at an impasse. Any help would be much appreciated. models.py from django.db import models from django.urls import reverse from django.contrib.auth.models import User from django.utils import timezone class Article
