I am new to Django and am trying to make an online journal, and the server runs fine, but when I press the create button, it does not redirect to the form even though a POST request is being sent. screenshot of the create page.

Django Variable Re-evaluation in Template
So let's say in my template, I use: <td> {{ model1.column1.column11.code1 }} </td> <td> {{ model1.column1.column11.code2 }} </td> <td> {{ model1.column1.column11.code3 }} </td> <td> {{ model1.column1.column11.code4 }} </td> <td> {{ model1.column1.column11.code5 }} </td> <td> {{ model1.column1.column11.code6 }} </td> <td> {{ model1.column1.column11.code7 }} </td> and for comparison: {% with col=model1.column1.column11 %} <td> {{ col.code1 }} </td> <td> {{ col.code2 }} </td> <td> {{ col.code3 }} </td> <td> {{ col.code4 }} </td> <td> {{ col.code5 }} </td> <td> {{ col.code6 }} </td> <td> {{ col.code7 }} </td> {% endwith %} My questions are: For the first code, does it imply that the model1.column1.column11 will be queried by Django 7 times? For the second code, will the usage of with col=model1.column1.column11 can make the template rendering faster, as the query of model1.column1.column11 is only once from the {% with %} block, and just get the variables from the col? Are there any alternatives to both these approaches? Currently, my SQL table consists of less than 1000 rows so any performance issues may not be seen. But, my concern is when the SQL table is large enough and will require many optimization on the query. -

Making a search bar work in AlpineJS where the searched items in x-data come from x-init
Basically trying to modify the dynamic search bar that can be found in Alpine docs, but with "items" ("bands" in my case) coming from x-init that fetches a JSON. Outside of this search bar all the desired data from this JSON is displayed so it's not like the JSON itself is empty, but in this particular situation x-text doesn't even list any of the values, as if the JSON data never gets to the x-data/"bands" array. This is what I currently have, like I said it's a little modification of the search bar from the docs. <div x-data="{ search: '', bands: [], get filteredItems() { return this.bands.filter( i => i.startsWith(this.search) ) } }" x-init="bands = await (await fetch('/bands/')).json()"> <input x-model="search" placeholder="Search..."> <template x-for="band in filteredItems" :key="band"> <p x-text="`${band.name}`"></p> </template> </div> I'd be grateful if anyone told me what exactly this seemingly straightforward chunk of code is missing. -

Django - Counting ManyToMany Relationships
In my model, I have many Things that can have many Labels, and this relationship is made by user-submitted Descriptions via form. I cannot figure out how to count how much of each Label each Thing has.

For example: Cat 10 fluffy 6 fuzzy 4 cute 2 dangerous 1 loud I've tried a few things with filters and annotations like counts = Label.objects.filter(description_form = pk).annotate(num_notes=Count('name')) but I think there's something obvious I'm missing either in my views.py or in my template. -
