  • Normalizing Item Names & Synonyms

    - by RabidFire
    Consider an e-commerce application with multiple stores. Each store owner can edit the item catalog of his store. My current database schema is as follows: item_names: id | name | description | picture | common(BOOL) items: id | item_name_id | picture | price | description | picture item_synonyms: id | item_name_id | name | error(BOOL) Notes: error indicates a wrong spelling (eg. "Ericson"). description and picture of the item_names table are "globals" that can optionally be overridden by "local" description and picture fields of the items table (in case the store owner wants to supply a different picture for an item). common helps separate unique item names ("Jimmy Joe's Cheese Pizza" from "Cheese Pizza") I think the bright side of this schema is: Optimized searching & Handling Synonyms: I can query the item_names & item_synonyms tables using name LIKE %QUERY% and obtain the list of item_name_ids that need to be joined with the items table. (Examples of synonyms: "Sony Ericsson", "Sony Ericson", "X10", "X 10") Autocompletion: Again, a simple query to the item_names table. I can avoid the usage of DISTINCT and it minimizes number of variations ("Sony Ericsson Xperia™ X10", "Sony Ericsson - Xperia X10", "Xperia X10, Sony Ericsson") The down side would be: Overhead: When inserting an item, I query item_names to see if this name already exists. If not, I create a new entry. When deleting an item, I count the number of entries with the same name. If this is the only item with that name, I delete the entry from the item_names table (just to keep things clean; accounts for possible erroneous submissions). And updating is the combination of both. Weird Item Names: Store owners sometimes use sentences like "Harry Potter 1, 2 Books + CDs + Magic Hat". There's something off about having so much overhead to accommodate cases like this. This would perhaps be the prime reason I'm tempted to go for a schema like this: items: id | name | picture | price | description | picture (... with item_names and item_synonyms as utility tables that I could query) Is there a better schema you would suggested? Should item names be normalized for autocomplete? Is this probably what Facebook does for "School", "City" entries? Is the first schema or the second better/optimal for search? Thanks in advance!

  • How can I ignore an http request without clearing the browser?

    - by Timid Developer
    To prevent duplicate requests (i.e. pressing F5 right after clicking a command button), I've setup my page base class to ignore the request if it's detected as a duplicate. When I say 'ignore' I mean Response.End() Now I thought I've seen this work before, where there's an issue, I just Response.End() and the users page just does nothing. I don't know the exact circumstance in which this worked, but I'm unable to repeat it now. Now when I call Response.End(), I just get an empty browser. More specifically, I get this html. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=utf-8"></HEAD> <BODY></BODY></HTML> I setup the following test app to confirm the problem is not elsewhere in my app. Here it is: Add the following to an aspx form <asp:Label ID="lbl" Text="0" runat="server" /><br /> <asp:Button ID="btnAdd1" Text="Add 1" runat="server" /><br /> <asp:Button ID="btnAdd2" Text="Add 2" runat="server" /><br /> <asp:Button ID="btnAdd3" Text="Add 3" runat="server" /><br /> And here's the code behind file using System; namespace TestDupRequestCancellation { public partial class _Default : System.Web.UI.Page { protected void Page_Init(object sender, EventArgs e) { btnAdd1.Click += btnAdd1_Click; btnAdd2.Click += btnAdd2_Click; btnAdd3.Click += btnAdd3_Click; } protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) CurrentValue = 0; else if (Int32.Parse(lbl.Text) != CurrentValue) Response.End(); } protected void Page_PreRender(object sender, EventArgs e) { lbl.Text = CurrentValue.ToString(); } protected int CurrentValue { get { return Int32.Parse(Session["CurrentValue"].ToString()); } set { Session["CurrentValue"] = value.ToString(); } } void btnAdd3_Click(object sender, EventArgs e) { CurrentValue += 3; } void btnAdd2_Click(object sender, EventArgs e) { CurrentValue += 2; } void btnAdd1_Click(object sender, EventArgs e) { CurrentValue += 1; } } } When you load the page, clicking any button does what is expected, but if you press F5 at any time after pressing one of the buttons, it will detect it as a duplicate request and call Response.End() which promptly ends the task. Which leaves the user with an empty browser. Is there anyway to leave the user with the page as it was, so they can just click a button? Also; please note that this code is the simplest code I could come up with to demonstrate my problem. It's not meant to demonstrate how to check for dup requests.

  • Is it possible to parse a URL into it's composite components?

    - by Paul Alexander
    I'd like to parse an incoming URL into it's component parts for some pre-processing before passing it into the standard MVC routing logic. For example given your standard route {controller}/{action}/{id} and the URL /user/show/10 Is there a way to have the Routing system return a dictionary containing controller, action and id keys with their corresponding values?

  • CDI SessionScoped Bean results in two instances in same session

    - by Ryan
    I've got two instances of a SessionScoped CDI bean for the same session. I was under the impression that there would be one instance generated for me by CDI, but it generated two. Am I misunderstanding how CDI works, or did I find a bug? Here is the bean code: package org.mycompany.myproject.session; import java.io.Serializable; import javax.enterprise.context.SessionScoped; import javax.faces.context.FacesContext; import javax.inject.Named; import javax.servlet.http.HttpSession; @Named @SessionScoped public class MyBean implements Serializable { private String myField = null; public MyBean() { System.out.println("MyBean constructor called"); FacesContext fc = FacesContext.getCurrentInstance(); HttpSession session = (HttpSession)fc.getExternalContext().getSession(false); String sessionId = session.getId(); System.out.println("Session ID: " + sessionId); } public String getMyField() { return myField; } public void setMyField(String myField) { this.myField = myField; } } Here is the Facelet code: <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"> <f:view contentType="text/html" encoding="UTF-8"> <h:head> <title>Test</title> </h:head> <h:body> <h:form id="form"> <h:inputText value="#{myBean.myField}"/> <h:commandButton value="Submit"/> </h:form> </h:body> </f:view> </html> Here is the output from deployment and navigating to page: INFO: Loading application org.mycompany_myproject_war_1.0-SNAPSHOT at /myproject INFO: org.mycompany_myproject_war_1.0-SNAPSHOT was successfully deployed in 8,237 milliseconds.

  • jQuery: form input values turns up undefined

    - by Seerumi
    Having problem with this bit of code qith jQuery. it should pick the values from current form and then submit them, but when I try to get them with jQuery they always turn up undefined. I know the SQL results are fine since they show correctly in HTML table, so it must be my inferior javascript skills. New with jQuery and I'm at loss :( PHP/HTML: echo "<table>\n" while ($row = odbc_fetch_array($query)) { echo "<form class='catForm'>\n"; echo "<input type=hidden class='catID' name='catID' value='".$row['running_id']."'/>\n"; echo "<tr>\n"; echo "<td>".$row['running_id']."</td>\n"; echo "<td>".$row['site_id']."</td>\n"; echo "<td>".$row['main_category']."</td>\n"; echo "<td>".$row['map_name']."</td>\n"; echo "<td><input type=textfield class='bCatID' value='".$row['mapping_id']."' size=6/></td>\n"; echo "<td><input type=submit class='saveCat' value='Save'/></td>\n"; echo "<td><input type=submit class='killCat' value='Delete' /></td>\n"; echo "</tr>\n"; echo "</form>\n"; } echo "</table>"; jQuery: $(".catForm").submit(function () { var id = $(this).find('.catID').val(); var bCatID = $(this).find('.bCatID').val(); var dataString = 'id='+id+'&bCatID='+bCatID; $.ajax({ type: "POST", url: 'adminUI/bin/updateSCategories.php', dataType : 'json', data: dataString, success: function(data) { if (data.error == true) $('.failure').html("Error, save failed.").show().fadeOut(2000); if (data.error == false) $('.success').html("Saved succesfully").show().fadeOut(2000); }, error: function(XMLHttpRequest, textStatus, errorThrown) { $('.failure').html("Error, save failed.").show().fadeOut(2000); } }); return false; }); RESULT: id: undefined bCatID: undefined

  • Trying to understand the usage of class_eval

    - by eMxyzptlk
    Hello everyone, I'm using the rails-settings gem, and I'm trying to understand how you add functions to ActiveRecord classes (I'm building my own library for card games), and I noticed that this gem uses one of the Meta-programming techniques to add the function to the ActiveRecord::Base class (I'm far from Meta-programming master in ruby, but I'm trying to learn it) module RailsSettings class Railtie < Rails::Railtie initializer 'rails_settings.initialize', :after => :after_initialize do Railtie.extend_active_record end end class Railtie def self.extend_active_record ActiveRecord::Base.class_eval do def self.has_settings class_eval do def settings RailsSettings::ScopedSettings.for_thing(self) end scope :with_settings, :joins => "JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND settings.thing_type = '#{self.base_class.name}')", :select => "DISTINCT #{self.table_name}.*" scope :with_settings_for, lambda { |var| { :joins => "JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND settings.thing_type = '#{self.base_class.name}') AND settings.var = '#{var}'" } } scope :without_settings, :joins => "LEFT JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND settings.thing_type = '#{self.base_class.name}')", :conditions => 'settings.id IS NULL' scope :without_settings_for, lambda { |var| { :joins => "LEFT JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND settings.thing_type = '#{self.base_class.name}') AND settings.var = '#{var}'", :conditions => 'settings.id IS NULL' } } end end end end end end What I don't understand is why he uses class_eval on ActiveRecord::Base, wasn't it easier if he just open the ActiveRecord::Base class and define the functions? Specially that there's nothing dynamic in the block (What I mean by dynamic is when you do class_eval or instance_eval on a string containing variables) something like this: module ActiveRecord class Base def self.has_settings class_eval do def settings RailsSettings::ScopedSettings.for_thing(self) end scope :with_settings, :joins => "JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND settings.thing_type = '#{self.base_class.name}')", :select => "DISTINCT #{self.table_name}.*" scope :with_settings_for, lambda { |var| { :joins => "JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND settings.thing_type = '#{self.base_class.name}') AND settings.var = '#{var}'" } } scope :without_settings, :joins => "LEFT JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND settings.thing_type = '#{self.base_class.name}')", :conditions => 'settings.id IS NULL' scope :without_settings_for, lambda { |var| { :joins => "LEFT JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND settings.thing_type = '#{self.base_class.name}') AND settings.var = '#{var}'", :conditions => 'settings.id IS NULL' } } end end end end I understand the second class_eval (before the def settings) is to define functions on the fly on every class that 'has_settings' right ? Same question here, I think he could use "def self.settings" instead of "class_eval.... def settings", no ?

  • Prevent some DataColumns in a DataTable from being bound to DataGridView

    - by Rajarshi
    Is there any way I can specify that some columns in a DataTable will not be automatically bound to a DataGridView when I set the DataSource property of the DataGridView to the DataTable. For example, if I have a DataTable with columns as "Id, Name" then can I specify that Id column will not be shown in DataGridView? I know I can set some Visible property in DataGridView after it is bound, but can I specify in the DataTable/DataColumn itself?

  • Is it possible to use .ASPXAUTH for my own logging system?

    - by J. Pablo Fernández
    For a web application I switched from using ASP.NET Membership to using my own log in system which just does something like this to mark a user as logged in: Session["UserId"] = User.Id Is it possible to store the user id in the ASPXAUTH cookie, piggybacking on its encryption, instead of using the standard session? The goal is for the logged in state to last longer than a session and survive both browser and server restarts.

  • asp.net mvc & jquery dialog: What approach do I take to add items to a dropdownlist/select list with

    - by Mark Redman
    Hi, I am new to MVC and have a grasp of the basic model, but still doing everything with postbacks etc. One aspect of the UI I want to build is to have a drop-down-list of items with a button to add an item to the database and refresh the list. Achieving this with WebForms was straight forward as everything was wrapped in UpdatePanels, but what is the best approach to achieve this using MVC? Part of the markup for the list and button look like this: <table> <tr> <td><%=Html.DropDownList("JobTitleSelectList", Model.JobTitleSelectList, "(select job title)", new { @class = "data-entry-field" })%></td> <td>&nbsp;</td> <td><a id="AddJobTitleDialogLink" href="javascript: addJobTitleDialog();" title="Add Job Title"><img id="AddJobTitleButtonImage" src="/Content/Images/Icons/16x16/PlusGrey.png" border="0" /></a></td> </tr> </table> The Dialog is a standard jquery Ui dialog, looks like this: <div id="SingleTextEntryDialog" style="display:none"> <table> <tr> <td>Name:</td> <td><input id="SingleTextEntryDialogText" type="text" size="25" /></td> </tr> </table> </div> I am guessing I need to put this into a UserControl / PartialView (are they the same thing?) Also with the strongly typed View how do I pass the Model or just the SelectList Property to the UserControl or is this not the case? Nor sure if there should be form in the dialog div? or how that is going to postback via ajax. Some examples show a lot of ajax code in the page something like: $.ajax({...}); I assume doing this using jquery is more code than asp.net webforms, but there is just more code to see doing a "View Source" on a page? Your comments appreciated.

  • How can this PHP/FQL code be modified to increase the performance and usability?

    - by Kaoukkos
    I try to get some insights from the pages I am administrator on Facebook. What my code does, it gets the IDs of the pages I want to work with through mySQL. I did not include that part though.After this, I get the page_id, name and fan_count of each of those facebook IDs and are saved in fancounts[]. Using the IDs ( pages[] ) I get two messages max from each page. There may be no messages, there may be 1 or 2 messages max. Possibly I will increase it later. messages[] holds the messages of each page. I have two problems with it. It has a very slow performance I can't find a way to echo the data like this: ID - Name of the page - Fan Count Here goes the first message Here goes the second one //here is a break ID - Name of the page 2 - Fan Count Here goes the first message of page 2 Here goes the second one of page 2 My questions are, how can the code be modified to increase performance and show the data as above? I read about fql.multiquery. Can it be used here? Please provide me with code examples. Thank you $pages = array(); // I get the IDs I want to work with $pagesIds = implode(',', $pages); // fancounts[] holds the page_id, name and fan_count of the Ids I work with $fancounts = array(); $pagesFanCounts = $facebook->api("/fql", array( "q" => "SELECT page_id, name, fan_count FROM page WHERE page_id IN ({$pagesIds})" )); foreach ($pagesFanCounts['data'] as $page){ $fancounts[] = $page['page_id']."-".$page['name']."-".$page['fan_count']; } //messages[] holds from 0 to 2 messages from each of the above pages $messages = array(); foreach( $pages as $id) { $getMessages = $facebook->api("/fql", array( "q" => "SELECT message FROM stream WHERE source_id = '$id' LIMIT 2" )); $messages[] = $getMessages['data']; } // this is how I print them now but it does not give me the best output. ( thanks goes to Mark for providing me this code ) $count = min(count($fancounts),count($messages)); for($i=0; $i<$count; ++$i) { echo $fancounts[$i],'<br>'; foreach($messages[$i] as $msg) { echo $msg['message'],'<br>'; } }

  • Creating a generic NotFound View in ASP.MVC

    Hello guys, I'm having a problem to create a generic View to represent NotFound pages. The view is created and it's fine.

  • Pass a variable into a trigger

    - by Codesleuth
    I have a trigger which deals with some data for logging purposes like so: CREATE TRIGGER trgDataUpdated ON tblData FOR UPDATE AS BEGIN INSERT INTO tblLog ( ParentID, OldValue, NewValue, UserID ) SELECT deleted.ParentID, deleted.Value, inserted.Value, @intUserID -- how can I pass this in? FROM inserted INNER JOIN deleted ON inserted.ID = deleted.ID END How can I pass in the variable @intUserID into the above trigger, as in the following code: DECLARE @intUserID int SET @intUserID = 10 UPDATE tblData SET Value = @x PS: I know I can't literally pass in @intUserID to the trigger, it was just used for illustration purposes.
