ruby - trouble in passing select tag values in a rails application -

new on rails, having problem in passing select_tag value(in view file) controller.

my view controller file like

class projectstatuscontroller < applicationcontroller def index @projects = project.find(:all, :select => "name") end def show lookup = params[:project] @rows = project.find_by_lookup(lookup) end end

and view file like

<% form_tag("project_status", :controller => "projectstatus", :action => "show", :method=>'get' ) %> <%= select_tag 'project', options_from_collection_for_select(@projects,"id", "name"),:onchange => "this.form.submit();" %> <% end %> <% if !@rows.nil? @rows.each |row| end %> <%= row[:name] %> <% end %>

what want accomplish - based on selected value select tag want display information(on same view page) of selected item database

first of should write <%= form_tag not <% form_tag

than, it's unusual extract select field id(options_from_collection_for_select(@projects,"id", "name"))

but in method show search record field lookup

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
