Defaults

View Source

You can assign default values to fields in your resource configuration file. This is useful when you want to provide a default value for a field that is not required.

Configuration

To define a default value for a field, you need to set the default option in the field configuration. The default option has to return a function that receives the assigns and returns the default value.

# in your resource configuration file
@impl Backpex.LiveResource
def fields do
[
    username: %{
        default: fn _assigns -> "Default Username" end
    }
]
end

The example above will assign the default value "Default Username" to the username field.
