Django models avoid duplicates

Question

In models:

class Getdata(models.Model):
    title = models.CharField(max_length=255)
    state = models.CharField(max_length=2, choices=STATE, default=\"0\")         


        

Answer 1

I think injecting a Jquery/JS code to hide the save button would be a good idea.

Create a custom_validate.js file like below and place it in directory static(static file directory)

if (!$) {
    $ = django.jQuery;
}

$( document ).ready(function() {
    $("[name=_save]").click(function() {
       $("[name=_save]").css("visibility", "hidden");
    });
});

And in admin.py, add the below code.

class CustomDataForm(forms.ModelForm):

    class Meta:
        model = GetData

class GetDataAdmin(admin.ModelAdmin):
    # ....
    .....
    form = CustomDataForm

    class Media:
        js = ('/static/custom_validate.js', )
