Conditionally add attribute in angular

Question

I want to use the $scope to set if an attribute should be used or not in angular. Here is my scope:

fields:
    [
        {
            label: 'First Name',
            name: 'firstname',
            key: 'entry.326845034',
            type: 'text',
            required: true
        }
    ]

it's the required attribute I want to set. I'm imagining something like {{if fields.required == true | required}}, but I can''t find any documentation on it.

Answer 1

Are you wanting to set required on a form element like this?

<input required>

If so you can use

<input ng-required="fields.required"> 

and the true/false state of the variable will end up applying or removing the required attribute on the input.
