Django Webpack Loader, in production django.cgi not rendering VUE.js dist/ file

Generate PDF Document From Django And Dot Net Core
I developed some web apps by Django and .NET Core which let user input the formatted text and saved to database by using TinyMCE editor. The formatted text will be saved as HTML text. I want to generate a PDF document which include the formatted text and the document has fixed format of every page. For example, the Purchase Order will show the Supplier and PO number on every pages. I try JasperReport community and FastReport Open Source but found that it is lack of HTML tags they supported. So the output of HTML text almost unformatted. Do you have any suggested Reprot Tools which have better support of HTML used in Django and .NET Core? Thank you! -

Uncaught TypeError: Cannot read property 'id' of undefined at HTMLParagraphElement.<anonymous>
I've been looking at this for ages and feel like I'm missing something obvious, any help much appreciated! I'm trying to create nested accordions to represent a Django model in a convenient way. Paragraph elements are created and given ids using a Django for loop. Then JS is used to assign functionality (code below). The title error points to the first id reference from this line, suggesting it is undefined. if (acc2[i].id.slice(acc2[i].indexOf("_")+1) === acc3[j].id.slice(acc3[j].indexOf("_")+1)) { However, using console.log I can get the expected values for these ids ("chain_name_1" and "chainseq_1" in the first iteration of the loop, when the error occurs).

Guidence on buliding a Django model

Django and PostgreSQL dynamic schema creation and model manipulation
I've been searching all day and given up. Django does not have proper support for Postgres schemas, hence the question.

The tables in each schema are identical to every those in every other schema but obviously the data is different (I want users to have their data isolated from each other).

When trying to create a new Django CreateView form, my forms are being populated with the data that was entered in the last form
Using Class Based Views, ModelForms, and Inlline Formsets. I’m making a recipe application in Django. Each user has their own OneToOne RecipeBook object, which in turn can hold as many recipes as needed, as each Recipe has a ForeignKey relationship to the RecipeBook object. There are also Ingredient and Direction objects that each have a FK relationship to the Recipe object. The good news is that I can create a Recipe object using my CreateView, with as many associated Ingredient and Direction objects as I want. The Ingredient/Direction objects should be unique to each Recipe object (and by extension, each User). However, when I create a Recipe object, and then I try to create a new Recipe object, its Ingredient and Direction fields are already populated on the new object, form the old object. So if I had just created a Recipe with 3 Ingredient/Direction fields all set to '1', and then go to create another Recipe, the new Recipe object will have all blank fields, but will have 3 Ingredient/Direction objects all set to 1. This will happen to each user that is logged in. I want to make it so these objects are all staying together. I think … -
