Django administrator. Hide field in change selection box
I have a model:
class CategoryField(models.Model):
selectfield = models.IntegerField(choices=SELECT_FIELD_CHOICES, default=1)
verified = models.BooleanField(default=True, verbose_name='Required?')
On the admin page I have selectField
with options: "value1", "value2", "value3", ... When I select "value2", I need to show the field verified
. How can i do this?

You need to add JavaScript to show or hide the field. jQuery 1.9.1 is available in the Django admin via an object django.jQuery
.
The easiest way to add this JavaScript is to add the Media meta-focus to your model form and add the form to ModelAdmin
:
# forms.py
from django import forms
class CategoryFieldForm(forms.ModelForm):
. . .
class Media:
js = ('category-field-admin.js',)
# admin.py
from django.contrib import admin
from your_app.forms import CategoryFieldForm
from your_app.models import CategoryField
class CategoryFieldAdmin(admin.ModelAdmin):
form = CategoryFieldForm
admin.site.register(CategoryField, CategoryFieldAdmin)
# category-field-admin.js
// pseudo code - change as needed
(function($) {
$(function() {
var selectField = $('#id_selectField'),
verified = $('#id_verified');
function toggleVerified(value) {
value == 'value2' ? verified.show() : verified.hide();
}
// show/hide on load based on pervious value of selectField
toggleVerified(selectField.val());
// show/hide on change
selectField.change(function() {
toggleVerified($(this).val());
});
});
})(django.jQuery);
