I have declared a charfield 'choice_text' in one of my models. I want to convert it to a dropdown box in django admin. The choices in the dropdown list depend on user input to a textbox defined in another model class. I have a javascript (declared  as Media class inside a ModelAdmin class) that reads user input in the textbox. But I am unable to this choice list back from .js file to django admin. How do I do that? Thanks in advance.

I have tried this.

models.py

class Routing(models.Model):

    choice_text = models.CharField(_('Choices'), max_length=100, default="(any)", null=False)

admin.py

class AdminRoutingInlineForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):

        super(AdminRoutingInlineForm, self).__init__(*args, **kwargs)

        CHOICES = [('a', 'any'),('b', 'blah'),]      // override this with choices from populate_dropdown.js (code below)

        self.fields['choice_text'].choices = CHOICES

class RoutingInlineAdmin(StackedInline):

    form = AdminRoutingInlineForm    

    fields = (('choice_text', 'next'),)

    model = Routing

class FormModelAdmin(ModelAdmin):

    inlines = [RoutingInlineAdmin]

    class Media:

        js= ("sforms/admin/populate_dropdown.js",)

populate_dropdown.js

(function($) {

    $(document).ready(function() {

       

        $("[id^=id_fields-][id$=_options_0]").each(function(){       // user input from this field will be used as choices

        choices = '(any),' + $(this).val().split("\n");

        alert(choices);

        

        // send this choices back to admin.py and override CHOICES in AdminRoutingInlineForm class

        });  

});
