Default value for input with simple_form

im trying to do default value for input

works ok:

<%= f.input_field :quantity, default: '1' %>

but i need f.input not f.input_field

<%= f.input :quantity %>

im trying it with standard html value - but after unsucessfull validation quantity is overriden by 1 - undesired
```
<%= f.input :quantity, input_html: {value: '1'} %>
```
when i remove value and validation is unsucessfull quantity is populated - everything is ok
```
<%= f.input :quantity %>
```

how to solve this ? is there any alternative like in f.input_field - :default ? or there is any other solution with value ?

Solution 1:

You can try with something like this:

<%= f.input :quantity, input_html: {value: f.object.quantity || '1'} %>

You can use the selected option of simple_form: <%= f.input :quantity, selected: f.object.quantity || '1' %>

try this:

= f.input : quantity, input_html: { value: (f.object.quantity.present?) ? f.object.quantity : '1' }
