If You like me forget to update 'updateOrder' view. You can do this in "order_form.html' .. in input place this code: {% csrf_token %} {% if form %} {{form}} {% endif %} {% if formset %} {{ formset.management_form }} {% for form in formset %} {{ form }} {% endfor %} {% endif%}

Thanks! A good improvement would be trying to create one order with multiple items, since with this model, you have to generate multiple order if you have more than one item.

Adding formsets breaks updating orders (/update_order//)

[@soyadmohifulislam4323]

if someone has the error: " 'set' object has no attribute 'append' " then you should change the 'fields' data type set to tuple. I mean you should use normal brackets not curly braces. OrderFormSet = inlineformset_factory(Customer,Order,fields={'product','status'}) New: OrderFormSet = inlineformset_factory(Customer,Order,fields=('product','status'))

[@johnnyli2732]

Hi Dennis, Great Tutorials! Having one question on this inline formsets. How can I have an 'add' button to control the amount of forms I want dynamically? Tried with jquery, but the data was submitted to database instead of creating an extra form on the page..

[@shankarbalaji1916]

use button tag with type="button" for add button

[@letscodemore]

You can follow this article to add “Add More” button. www.letscodemore.com/blog/django-inline-formset-factory-with-examples/

[@prajithkrish5230]

Hey regarding the inline form sets ... is there a way to implement features such as adding fields and deleting fields individually, I searched the whole django world for this and literally your the closest one I can get

[@rayr268]

Search dynamic django forms. There are some articles online now.

[@davidbrown2806]

1. Why is there a "delete box" in the Order Form ??????? Do we need it ? Do we get rid of it ? 2. It would have been nice to see the other method, that does not use the loop. 3. I wonder if you could use the inline form feature to create a kit or package of individual parts that someone could buy, enter the package SKU and the form expands the package into individual orders. ie BBQ package .... includes BBQ grill, propane tank, and cooking utensils. Love to see it.

I was trying to message you but i had no idea where to reach you from, so i will just type my message right here, in this legendary django series i was following recently. I followed you step by step and currently i'm in part 11..it's the coolest tutorial i have ever watched, CAN'T DESCRIBE HOW HAPPY I AM while learning from your super skills!! It's literally the first time where i feel comfortable building a project while understanding every single step😍😍 It's been like 2 months since i subscribed to your channel, and i thank god i did. I just have one question to ask.. In almost every django tutorial, in the first steps of the project where we work with cmd and creating our directory, the instructor creates a virtual environment before django-admin startproject .... While in this series, we are building our project without any virtualenv created Why? 🤔🤔 I'm literally enjoying every minute building this CRM website and only have this question and again, THANK YOU. 🙏🙏🙏

[@lehuythinh6754]

About the virtualenv, it is for isolate the running system django is using. If you dont have the need of isolating it, then venv has no use.

[@adamhughes5527]

These are really great and covered a bunch of things my knowledge was a bit vague on! :D

[@anindyasikdar3221]

I'm confused with when to use instance and when to use initial. Are they interchangeable? Any help will be appreciated. Thanks!

[@LIMLIMLIM111]

instance refers to one of the objects in a model. Initial pre-fills form's fields. Using the Instance argument does pre-fill the form, but it's an "extra feature", not the main functionality.

[@LIMLIMLIM111]

"No, there's quite a difference. "Initial" is used to set the initial values and is quite appropriate when a *new* model instance is going to be created. The "instance" is used when you want the ModelForm to be used to update an existing instance of a model. Since Django does not currently incorporate mind-reading technology, if the two parameters were merged into one, the framework wouldn't know whether it's meant to be updating an existing instance or creating a new one." from: groups.google.com/g/django-users/c/wi6yOo3N0FU

[@franklinguang]

Hi Dennis, thanks for this selfless effort. It really help. I got to a stage where I got stuck with one page handling multiple forms. One to update exiting instance, one to add new entry data. Could you make a video address how these can be done?

[@jamesarthur2120]

form = OrderForm(initial ={'customer': customer}) is not auto filling the customer's name in the forms

[@kimjay6806]

I'm aware this is coming after 4months, but for anyone who is confused: remove the "else" code bit. else: form = OrderForm() with: " form = OrderForm(initial ={'customer': customer}) " towards the top of the createOrder function, you are creating an OrderForm instance (" form ") which is temporairly loaded (at runtime) with the values in the " initial " dictionary. If you continue to have that bit of code along with the "else" code (towards the bottom of the function), the "else" code bit takes precedents (because the code is read from top to bottom) and ignores populating the form with what's in the initial dictionary. The "else" code creates an unbounded form instance. Hope it makes sense.

[@DennisIvy]

Yes, sorry about that. I updated this in the source code but I'll make a video fixing this bug soon. The problem is that in "order_form.html" we reference the "formset" but in the "updateOrder" we pass in "form". The fix for now is to change the context dictionary in the "createOrder" view to pass in the formset as form: context = {'form':formset}. Then change the name in order_form.html for "form" instead of formset & loop the the form by field: {% csrf_token %} {{ form.management_form }} {% for field in form %} {{field}} {% endfor %} Hope this makes sense for now.

[@davidbrown2806]

We can you only place one item per order, should this be changed to allow for multiple line items ? What about ordering packages ie some computer component companies generate build lists for computer builds of various attributes and prices. How cool would it be to create a 'package list' as a item, order that item and it automatically generates a multiple line order of the individual components. Just a thought. Also looks like the timestamp in settings.py has not been set for the proper timezone. Either that or format the Date Order to drop the time.
