I am looking for a simple way to implement inline editing in a table (with Django). I did not test stuff like Django-Front or django-inlineedit so far. I already found out, that not all simple solutions work for me. jqInlineEdit and inline-edit.jquery.js do work only with unique selectors, as I described here.

With jQuery.editable (jquery.inline-edit.js), I do not have these problems, but I do not know how to get the id and save the data.

I am trying to insert 8 images and a button in a div in a bootstrap Joomla template. I need the images to be vertically aligned in the centre and horizontally evenly aligned over the with in all responsive views (mobile, tablet, small laptop, large screen with max 1920px of with). This is my test website:

webdisenjo.nl and the logo div is "moduletable logos_home"

I am struggling with what the with of the image should be and how to place them in the div.

Now, I have tried this class.

but it does not work well.

I have also tried this class

Given the following (simplified) models:

I used this tutorial to successfully set up a dynamic inline formset using Django. The CreateView works great, but I cannot get the UpdateView to actually update the related fields. There are no errors thrown, but the items will not update. I believe I have isolated the error to the form_valid function. The code is as follows. Thank you for any assistance.

I'm following this tutorial to create an object creation formset. The goal is to allow multiple images connected to a car object via Foreign object, to be uploaded in a single form.

The images use a formset that has one image per field, with as many 'add another image' fields dynamically created.

Running the server raises this error: "NameError: name 'CarImageForm' is not defined" when self-referencing the class which encloses the definition.

I've looked through the code and found a few minor corrections, but none seem to solve this.

I am trying to make loader which will look like this on

CodePen

But I need to have rounded borders, and rectangle, not a box. So I will be able to place the logo of our company to the loader.

I tried to make one more layer, which will be making inline radius and to the wrapper, I set border-radius and overflow: hidden.

But, the animation looks horrible And isn't smooth.

Can you please help me, to make this animation better? Or did you create something similar?

UPDATE CODE SASS

I am still experimenting with that.

I'm working on a Virtual Library app (using Django v2.1, python v3.5) where anyone should be able to access the book catalog and request a loan by simply leaving some personal info like name, surname, email, etc.

These are some of the models in models.py:

I am following this particular tutorial (tutorial link) to get my dynamic formsets working. I encountered this error which I am not sure where is it originated from or how to resolve it. Can someone tell me what could be done to resolve it? Yes, I know that this is a repetitive question here in SO. I have gone through many of those answers, but could not figure it out in my case.

I am trying to add validation to my Django forms.

I want to require at least one child model for my inlineformset.

I am still getting an error
