changing ID of form input element in django when it's created

Question

When django creates a form the id for the input are the following:

<input id="id_name"..../>

How do I change the id to let's say "test"?

Has to be somehow in the form.py, right?

class ReviewForm (forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(ReviewForm, self).__init__(*args, **kwargs)
        self.fields['location']=forms.CharField(label='', required=False)
        self.fields['review']=forms.CharField(label='', required=False)

Answer 1

When you instantiate your form, you'll want to call it with the auto_id keyword set to a string with the format character '%s' which will be replaced by the field name.

So you'll want to do this:

ReviewForm(auto_id="test_%s")

And your ids will be generated with test_ as a prefix, followed by the field name.

Direct from the Django 1.8 docs:

Use the auto_id argument to the Form constructor to control the id and label behavior.

...

If auto_id is set to a string containing the format character '%s', then the form output will include tags, and will generate id attributes based on the format string. For example, for a format string 'field_%s', a field named subject will get the id value 'field_subject'.

I found a way to do this, explained here

[class ReviewForm (forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(ReviewForm, self).__init__(*args, **kwargs)
        self.fields\['location'\]=forms.CharField(widget=forms.TextInput(attrs={'id':'myField'}),label='', required=False)
        self.fields\['review'\]=forms.CharField(widget=forms.TextInput(attrs={'id':'myField'}),label='', required=False)
