Rails link_to link fills out form on page

Rails 4.0 Ruby 2.0

I am trying to create a link that fills out a textarea field on the current page with data that I already have.

Here is my code for the view (that doesn't work)

<% if feed_item.in_reply_to %>
<%= link_to "reply", mentions_path(:content => "@#{feed_item.user.username}") %>
<% end %>

All I want is @#{feed_item.user.username} to be entered into a textarea called micropost_content

Any help or something that'll point me in the right direction would be great

--C

EDIT:

Everyone seems to be confused with the @...I'm putting the @ because I want it to display on the page as

@usernmae

Since the username is stored as username in the DB.

It's not because I'm trying to insert an "instance variable" :-)

Can't this be done with Javascript?

This better explains it:

Things to do and check (just in case):

  • check that mentions_path is routing to the correct controller and action, where you want the form
  • remove the @ from the evaluated string and check the params[:content] value in the controller, it should contain the correct username
  • if you are using a form_for helper in the view
    • then assign that content to the appropriate field of the model, that you are building the form for
  • else
    • assign that content to an instance variable like @username and then use text_area_tag :field_name, @username

Ok, if you need that on the same page just do something like 

$(document).ready -> 
  $("#reply_link_id").click ->
    username = $('#username_link_id').html()
    $('#textarea_id').val(username).focus()
    return false

I got the behavior I was looking for by doing this

<%= link_to "reply", '#', :onclick => "document.getElementById('micropost_content').value='@#{feed_item.user.username} ';return false;" %>

Although now I am looking for a way to put the cursor there

on the new page you can check if the value that you are passing exist and added to the value of the field that you want populated
