Retrieve value of text_field_with_auto_complete field

Dear all,

I created a form with 2 text_field_with_auto_complete fields and a
submit button. I am able to get the auto complete feature to work.
However, I am unable to read the values of the two text fields when I
click the submit button. The classic way with @varname params[:field_value] does
not seem to work.

Thanks,

Nick,

m''kkayyy, basic questions first:

- Are your fields indeed *in* the form you''re submitting, DOM-wise?
- Did you make sure they were provided with a non-empty name= attribute?
- At submission time, are they deemed successful (e.g. enabled, in this
  case)?

If all this fails, two more paths:

- Hook a handler to the form''s submit event and console.log or alert
its
serialize() method result.  Check for your fields.
- Post the details of your form opening and helper calls, in template
order, in this thread...  Maybe we''ll see something you forgot to
mention.

Re: Retrieve value of text_field_with_auto_complete field

Thanks for your answer. I''m new to ruby and here is my code:

index.rhtml:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <meta http-equiv="content-type" content="text/html;
charset=utf-8"/>    <title>Mezzoo.com</title>

    <%= javascript_include_tag  :defaults %>

  </head>
  <body>

    <h1>Input Places</h1>
    <fieldset>
        <% form_tag do %>
            <p>
                <label for="search2_origin_place">Origin
Place:</
label>
                <%= text_field_with_auto_complete :city, :namestate %>
            </p>
            <p>
                <label
for="search2_destination_place">Destination
Place:</label>
                <%= text_field_with_auto_complete :city, :namestate %>
            </p>
            <p>
                <%= submit_tag "Start Search" %>
            </p>
            <% end %>
        </fieldset>
    </body>
</html>

-------------------------------------
here is the controller code for search2_controller.rb:

class Search2Controller < ApplicationController

  auto_complete_for :city, :namestate

  def index

    if request.post?
      @origin_place = params[:origin_place]
      @destination_place = params[:destination_place]
      redirect_to({ :action => "map_places",  :origin_place =>
@origin_place,
                                              :destination_place =>
@destination_place, })
    end

  end

  def map_places()

    @origin_place = params[:origin_place]
    @destination_place = params[:destination_place]

  end

end

------------------------------

Here is the code for map_places.rhtml:

<h1>Map Places</h1>

<p>
    Origin Place: <%= @origin_place %>
</p>

<p>
    Destination Place: <%= @destination_place %>
</p>

---------------

I must be missing something easy.

Thanks,

Re: Retrieve value of text_field_with_auto_complete field

I actually got a little better. I updated the search2_controller.rb
index method code with this:

  def index

    if request.post?
      @origin_place = params[:city][:namestate]
      @destination_place = params[:city][:namestate]
      redirect_to({ :action => "map_places",  :origin_place =>
@origin_place,
                                              :destination_place =>
@destination_place, })
    end

  end

Now I am able to get the origin_place. However, destination_place is
the same as origin_place. The URL generated by the clicking the Submit
button is:

http://localhost:3001/search2/map_places?destination_place=Ambler%2C+PA&origin_place=Ambler%2C+PA

How come is it returning the same city name for both origin and
destination ?

Thanks,

Nick,

Re: Retrieve value of text_field_with_auto_complete field

Hey Rick,

Since you use the exact same code for both your AC''s, they share the
same default name for their respective fields.  I didn''t test, but this
probably means you''ll get both serialized under the same name, with no
trailing ''[]'' on the name, meaning you''ll only fetch
one of the fields
from the server side.  You need to provide more parameters to your
helper functions so that they equip your two fields with specific nameand id=
attributes.

BTW, since there are no differenciating parameters for their IDs, the
for= attributes in your labels are useless...

On a sidenote, <fieldset> is designed to be *inside* a <form>, and
is
rather useless without a child <legend> element.
