formtastic - how to prepopulate a string input with a value

formtastic, ruby-on-rails

Solution

Yup, you got the right answer all by yourself! Formtastic's rdoc is a mess, but we're working on it. Another option if you want this purely at a view level is to use the `:input_html` option, which gives you direct access to HTML attributes of the input tag:

f.input :email, :input_html => { :value => params[:email] }

Problem

I'm building an app, where users can give comments by just leaving their email to the comment. I want them to be able to register directly from there, by a link with their email adress as a param (like: `<%= link_to register_path(:email => @comment.email %>` ) - so there is no existing user record yet. this should be done by applying a value to the `form.input` field via the `:value` option. But the following code doesn't work! ``` <%- if params[:email] -%> <%= f.input :email, :required => true, :value => params[:email] %> <%- else -%> <%= f.input :email, :required => true %> <%- end -%> ``` I had a look inside the formtastic rdoc and inside my local gem but couldn't find any option for that. Suggestions anyone?
