Currently, I have a situation where I have a table for zip codes and another table for persons. The goal is to automatically populate the city field in the person's table based on the zip code entered. It seems like this functionality may not be achievable with Django alone, and I might need to explore jQuery, Ajax, or JavaScript for a solution.
Here are the model definitions in models.py:
from django.db import models
class Zip(models.Model):
zipcode = models.IntegerField()
city = models.CharField(max_length=200)
def __str__(self):
return str(self.zipcode)
class Person(models.Model):
name = models.CharField(max_length=200)
zipcode = models.ForeignKey('Zip',on_delete=models.CASCADE,related_name="zip_of_this_person")
personcity = models.CharField(max_length=200)
def __str__(self):
return self.name
Below are the form definitions in forms.py:
from django import forms
from .models import Zip, Person
class ZipForm(forms.ModelForm):
class Meta:
model = Zip
fields = ('zipcode', 'city',)
class PersonForm(forms.ModelForm):
class Meta:
model = Person
fields = ('name', 'zipcode', 'personcity' )
Here is the content of views.py where the form handling and rendering is defined:
from django.shortcuts import render, redirect, get_object_or_404
from .forms import PersonForm, ZipForm
from .models import Zip, Person
# Relevant view functions are defined here
Lastly, the HTML template:
{% extends 'theapp/base/base.html' %}
{% load static %}
{% block title %}Title Tab{% endblock %}
{% block site_css %}{% endblock %}
{% block main_heading %}{% endblock %}
{% block header_content %}{% endblock %}
{% block body %}
<section>
<h2>Person</h2>
</section>
<article class="post">
<h2>Name:{{ post.name }}</h2>
<p>Zip/city:{{ post.zipcode }}{{ post.personcity }}</p>
</article>
{% endblock %}
I have done extensive research but haven't found a clear solution. It seems to be a challenge especially since displaying all related data is simpler. This might be a frontend issue rather than a Django-specific one, despite using a relational database. Any guidance on this matter would be greatly appreciated.
