How to make radio button checked by default based on different user role?

Question

<% if role.name == "Administrator" %>
     <%= f.radio_button:status,'available', :checked => (params[:status] == nil ? true : params[:status]) %><label>Available</label>
     <%= f.radio_button:_status,'not available' %><label>Not Available</label>
<% else %>
     <%= f.radio_button:_status,'available' %><label>Available</label>
     <%= f.radio_button:_status,'not available' %><label>Not Available</label>
<% end %>

By default i want the available radio button to be checked in case of administrator and not available radio button for rest of user. But he can change it and when viewing for editing it should show the one he/she has selected and not the default one.

How can i do this? please help me.

Answer 1

Try the following code.

<%= f.radio_button:_status,'available', :checked => (role.name == "Administrator") %><label>Available</label>
<%= f.radio_button:_status,'not available', :checked => (role.name != "Administrator") %><label>Not Available</label>

This will not work, because checked will always be true if it is inserted in an HTML element, no matter what it is set as. You can read more on it here – Kapor

Actually, this will work, at least in Rails 5 it does. – Melamine

It works because if checked is false, Rails does not include the attribute. – Reparable

Answer 2

If you take a look at the documentation for rails radio_button_tag you would see it accepts the following params:

radio_button_tag(name, value, checked = false, options = {})

So it would be enough the following code

<%= f.radio_button:_status,'available', role.name == "Administrator" %><label>Available</label>
<%= f.radio_button:_status,'not available', role.name != "Administrator" %><label>Not Available</label>

Without the need of adding a "checked" property that might result in an unwanted behaviour
