Failing to render object data from Django API to Vuejs frontend
I've worked with Django 3.x for almost two years now and have just started using Vue js for about a week using the documentation to try and learn the intended way. So far my api access points work as intended whenever I DON'T use the Vue frontend to create objects. So, down to the code. I've tried to send the report via a prop from the Home.vue to the Detail.vue but for some reason it doesn't seem to load more than the noc_ticket. Just in case, the main.js for the router was made in haste when I was learning, I doubt its the issue, but you never know. Here is my monke code: Home.vue <template> <div class="home"> <div class="container"> <div class="container-fluid"> <h1 class="mt-4">Dashboard</h1> <ol class="breadcrumb mb-4"> <li class="breadcrumb-item active">Dashboard</li> </ol> <div class="row"> <div class="col-xl-3 col-md-6"> <div class="card bg-primary text-white mb-4"> <div class="card-body">Report Archive</div> <div class=" card-footer d-flex align-items-center justify-content-between " > <a class="small text-white stretched-link" href="" >View Details</a > <div class="small text-white"> <i class="fas fa-angle-right"></i> </div> </div> </div> </div> <div class="col-xl-3 col-md-6"> <div class="card bg-danger text-white mb-4"> <div class="card-body">Initial Report</div> <div class=" card-footer d-flex align-items-center justify-content-between " > <a class="small text-white stretched-link" href="" >View Details</a > <div class="small text-white"> <i … -

Django ajax dropdown with dynamic view button to access another page
I have created an ajax dropdown list and would like to insert a view button next to the second and third drop down. The view button on the second and third dropdown will bring me to another page that will show me more information on what was selected in the dropdown.

Use output of multiple views in one view with single url
So i am fairly new to Django and here is what i want: Say i have Three Views, View 1, 2 and 3. Each one with their own Template, Http response ,context and everything. Now i know how to Use 3 separate URLs for each view but what i would like to do is Just have one url for say View 3 and Outputs of View 2 and 3 are merged or concatenated whatever you wanna say in the view 3 itself. I am doing this because i have a lot of context and doing one view and single template results in a large code. At the moment i am using Class Views but i am open to you use function views. I want to know if there is a way i can Get Output/Results of View 1 and 2 in View 3 combined. Note: If someone is familiar with React and the components thats kind of what i am trying to do. Like making two components separately and then have a container component to call them. P.S. i am not using react i just thought this will explain what i am trying to do. -

Django Auth Group refuses to change in UpdateViews
I'm having a problem to update the User Group field after the User creation. The focus here is do this kind of thing outside the Admin page, in common UpdateView that will have limited access for certain groups. What bugged me is that the Group selection and saving of the EditForm and EditView is identical to the CreationForm/CreationView, and those work flawlessly.

Structure of an HTML post Request vs Django HTML Post Request
I have the following HTML form code which I am trying to translate to Django Templating Language. <form action="https://webto.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8" method="POST"><input type=hidden name="oid" value="00D280000016jv0"> <input type=hidden name="retURL" value="https://url/form/"> <label for="first_name">First Name</label><input id="first_name" maxlength="40" name="first_name" size="20" type="text" /><br> <label for="last_name">Last Name</label><input id="last_name" maxlength="80" name="last_name" size="20" type="text" /><br> <label for="email">Email</label><input id="email" maxlength="80" name="email" size="20" type="text" /><br> <label for="phone">Phone</label><input id="phone" maxlength="40" name="phone" size="20" type="text" /><br> </select><br><input type="submit" name="submit"> </form> I've looked at Django Templating Tutorials which tells me to create a view however I don't think that's necessary. What is the Django equivalent of this code? -
To reload or not reload - Is it better to send data to the server via ajax and then reload the page to see the result or update the DOM using js?
I have a fairly complex Django (3.1) site. On a couple of pages, I have some html/javascript code for the user to add/edit/delete comments. The script packages the comment and other bits and sends it to the server in an ajax POST request so the comment can be added/updated/deleted to/from the database. The script then gets an acknowledgement from the server, and, currently, it reloads the page so the new/edited/deleted comment can be seen at the bottom of the page. It all works fine in Chrome and Firefox. My questions is: Is it better practice to have the script add/edit/delete the comment html directly in the DOM based on the ajax response, rather than just reloading the page with the updated data? Why or why not? Thanks! Mark -
Django SQLite regex query is slow. Local SQLite regex query is fast. Why?
I have a small SQLite3 app that's basically a database search. When I do from main.models import Customer queryset = Customer.objects names = queryset.filter(name__regex = "[^aeiou]ica$") list(names) in ./manage.py shell, Django takes up to 5 seconds to return this result. Meanwhile on my local machine, if I do the same query in the sqlite shell, sqlite> select * from main_customer where name regexp "[^aeiou]ica$"; I get the result in less than a second. Where does the difference come from? Can Django be made to match the speed of my local query?
