Rails - Jan 2007 - Can't pass parameters to Ziya controller using url_for

Hi All,

I''m stuck yet again.  I have an action on a controller that produces a
Ziya graph, which I call using the gen_chart() helper.  However, I
can''t
seem to pass more than one parameter through to the action.

<%= gen_chart( "overview_graph",
    url_for( :controller => ''graph'', :action =>
''graph'', :graph_id =>
GraphController::GRAPH_OVERVIEW, :start_date =>
@report_params[:budget_period][:start_date].to_f, :end_date =>
@report_params[:budget_period][:end_date].to_f, :size => 300 ),
    "#ffffff",
    300,
    300 ) %>

This just doesn''t work, however.  The start date is passed through to
the underlying action, but the rest of the parameters aren''t.  The HTML
generated by the gen_chart() helper is as follows:

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0"
height="300" id="overview_graph"
style="border:none;display:inline"
width="300"><param name="movie"
value="/charts/charts.swf?library_path=/charts/charts_library&amp;xml_source=/graph/graph?start_date=1136026800.0&amp;amp;graph_id=1&amp;amp;end_date=1198234800.0&amp;amp;size=300"></param><param
name="quality" value="high"></param><param
name="bgcolor"
value="#ffffff"></param><param name="border"
value="0px"></param><embed
bgcolor="#ffffff" height="300"
name="overview_graph"
pluginspage="http://www.macromedia.com/go/getflashplayer"
quality="high"
src="/charts/charts.swf?library_path=/charts/charts_library&amp;xml_source=/graph/graph?start_date=1136026800.0&amp;amp;graph_id=1&amp;amp;end_date=1198234800.0&amp;amp;size=300"
swLiveConnect="true" type="application/x-shockwave-flash"
width="300"></embed></object>

I think the problem may have something to do with the encoding of the &
characters in the URL, but I''m not certain.

Anyone got this going themselves & care to shed some light on what
I''m
doing wrong? TIA :-)

Yours,
Duncan Bayne

Try passing :escape => false to url_for.
