Rails - Aug 2009 - Textbox input for an action: failed attempt

Okay, so this is what I have (which fails miserably) in my view:

Please enter a username:
<%= form_remote_tag :html => { :update => "filter_counts",
  :url => {:action => "search_by_name"} }do -%>
<div><%= text_field_tag ''username'', :maxlength =>
15, :size => 12
%></div>
<div><%= submit_tag ''Search'' %></div>
  <% end -%>


"filter_counts" is a div, "search_by_name" is the action, I
think the
rest makes sense.

And here is my error:

compile error
C:/scripts/Rads/app/views/dictated_exams/index.html.erb:5: syntax error,
unexpected '')''
  :url => {:action => "search_by_name"} }do ).to_s)
                                             ^
C:/scripts/Rads/app/views/dictated_exams/index.html.erb:36: syntax
error, unexpected kENSURE, expecting '')''
C:/scripts/Rads/app/views/dictated_exams/index.html.erb:38: syntax
error, unexpected kEND, expecting '')''

Extracted source (around line #5):

2: <center>
3: Please enter part of a name (''%'' is the wild card
character):
4: <%= form_remote_tag :html => { :update => "filter_counts",
5:   :url => {:action => "search_by_name"} }do -%>
6: <div><%= text_field_tag ''username'', :maxlength
=> 15, :size => 12
%></div>
7: <div><%= submit_tag ''Search'' %></div>
8:   <% end -%>

Fixed it.
Note the teeny differences..

<% form_remote_tag :update => "filter_counts",
  :url => {:action => "name_filter"} do -%>
  <%= text_field_tag ''search'', nil, :maxlength => 15,
:size => 12  %>
  <%= submit_tag ''Search'' %>
<%  end -%>

I don''t know how much this helps, but I''ve learned the hard
way that,
when I write

<%= blah :blah, :blah do |x| %>
<% end %>

I get bizarre (and always incorrect) results.


The reason is that <%= ... %> results in a string that gets inserted
into your HTML stream, while <% ... %> results in some Ruby code that
gets executed with no output going to the HTML stream.  If the Ruby
code includes a block, then, presumably, that block will output the
HTML stuff you were hoping to output.
