django-forms | A Django template-based form api | Form library

So, in my application I currently am receiving and storing some data,the structure currently is based around this:

• Each application has a number of devices
• Each device has incoming data from its sensors
• Each sensor has a type (e.g. temperature/humidity/etc)

Initially, I had wanted to find a solution to store the data dynamically into one table for all data, with a model that might look like this:

When deploying Django to Heroku, I get a ModuleNotFoundError: No module named 'env' error.

Anyone know why it is looking for that module?

Here is my requirements.txt:

My goal is to have a simple form that allows a user to input a function to graph, along with a display window, and once the user hits the submit button, I would like numpy and matplotlib to take the form data and generate a figure, then display that figure in the new web page.

So far, I followed this where it says "Create the Contact Form View" to get the form to generate and make the data usable. I found this which allows me to display the image. However, the image takes up the whole browser window like so. I would instead like that image to display in my web page. I'm very new to Django, so sorry if this doesn't make sense or isn't enough info. I'd love to give clarification or additional info if needed.

Here is my app's views.py:

Create the same form that shows on Django admin on templates.

I cannot load the foreign keys into the forms. I was searching for a solution for two days. I have read the Django documentation for ModelForm and QuerySet but I cannot find the solution. If anyone here can help me, it´s gonna be awesome. Thanks for your time!

models.py:

I have a formset that I created using formset_factory() with the can_delete option set to true

In my html template each form is displayed with the form.as_p function so I don't have access to each html element

the can delete field is displayed by the template as a check box and I would like to hide it.

I could render the form manually a modify the appropriate tag but since there is a lot of fields in that form that seems to be a lot of code just to hide an element

I could also use javascript or css on the client side as explained here

However I suspect there might be a neater way to do it.

I read in the doc that there is also a can_order field which is similar to can_delete and that can also be activated when creating a form set. This can_order field can be hidden by creating a formset class with the appropriate attribute :

I know that Django has default config of SSR (server-side rendering) but all the articles I have gone through mention that the Django-forms are rendered on server side and then sent to the browser. No specific information on the use case when javascript is mixed in the template.

I want to know if I use jquery tables in my Django template. Does that still render on server side? If yes then how does it render Javascript/jquery on the server-side?

I'd be glad if someone corrects me if my question itself has invalid argument.

I would like to kindly ask you for your help. I wanted to create simple voting system. I somehow succeeded. I have simple "UP" button that post form with simple +1 integer for scorevalue of post. It have a lot of problems right now but I will fight with them later.

Right now I wanted to add this +1 score without refreshing page (like most modern websites). I did my googling and I came up with this: https://www.codingforentrepreneurs.com/blog/ajaxify-django-forms/ I have to say that it is working quite well, even with my zero knowledge about js, jquery or ajax.

My problem is, that javascript is adding this +1 but it also is giving me some errors that I cannot grasp:

I have the following form in my forms.py. For some reason the override of label and help_text for username field WORKS and (both) the password fields doesn't.

I want to iterate through a list of checkboxes. When I use a single checkbox it works, but when I iterate through the checkboxes, I get
