How to use a ruby variable as the default value in simple_form?

Question

Good sirs:

I have this

 <%= f.input :name, :input_html => { :value => '<%= @user.name %>' } %>

and the erb tags within erb tags brings joy to no one.

How to do it correctly?

Why not just remove the erb tags?

<%= f.input :name, :input_html => { :value => @user.name } %>

Use it as value: @user.name:

<%= f.input :name, :input_html => { :value => @user.name } %>

If the form builder object f in your case is for the @user instance then the value will be pre-populated in case of validation errors. For example, the following will suffice:

<%= simple_form_for @user do |f| %>
  <%= f.input :name %>
<% end %>

The form is not for user which is why I have to force the attributes from user as defaults.
