  • JQuery tablesorter - Keeping grouped subheaders together, but still sorted

    - by hfidgen
    Hiya, I'm not really a Javascript programmer, so I'm struggling with this! I'm using the tablesorter plugin along with the Tablegroup plugin, which work very nicely to group the table rows by a parent, and then sort the parents. My problem is though, that I'd also like the child rows to be sorted whilst within the parent group I've done my best to get this working but I'm afraid I've hit a wall. Can anyone suggest a new starter for 10? The example below is working fine - There are 2x groups here: Nordics (Norway and Denmark) DACH (Germany and Austria) If I click on the header row, the groups are sorted, but the child rows within the group are not sorted. <script type="text/javascript"> $(document).ready(function () { $(".tablesorter") .tablesorter({ // set default sort column sortList: [[0,0]], // don't sort by first column headers: {0: {sorter: false}} , onRenderHeader: function (){ this.wrapInner("<span></span>"); } , debug: true }) }); </script> <table id="results-header" class="grid tablesorter table-header" cellpadding="0" cellspacing="0" border="0"> <thead> <tr class="title"> <th class="countries">&nbsp;</th> <th>% market share</th> <th>% increase in mkt share</th> <th>Target achieved</th> <th>% targets</th> <th>% sales inc. M-o-M</th> <th>% sales inc. M-o-M for country</th> <th>% training</th> </tr> </thead> <tbody> <tr id="Nord" class="collapsible parent parent-even collapsed"> <td class="countries">Nordics</td> <td>39.5</td> <td>49</td> <td>69.8</td> <td>51.8</td> <td>43</td> <td>42.5</td> <td>38</td> </tr> <tr id="row-Norway" class="expand-child child child-Nord"> <td class="countries">Norway</td> <td>6</td> <td>45</td> <td>101</td> <td>10</td> <td>20</td> <td>40</td> <td>30</td> </tr> <tr id="row-Denmark" class="expand-child child child-Nord"> <td class="countries">Denmark</td> <td>10</td> <td>20</td> <td>3</td> <td>40</td> <td>50</td> <td>25</td> <td>8</td> </tr> <tr id="DACH" class="collapsible parent parent-odd collapsed"> <td class="countries">DACH</td> <td>77</td> <td>61</td> <td>43</td> <td>98</td> <td>65</td> <td>92.5</td> <td>59.5</td> </tr> <tr id="row-Germany" class="expand-child child child-DACH"> <td class="countries">Germany</td> <td>56</td> <td>24</td> <td>84</td> <td>98</td> <td>32</td> <td>87</td> <td>21</td> </tr> <tr id="row-Austria" class="expand-child child child-DACH"> <td class="countries">Austria</td> <td>98</td> <td>98</td> <td>2</td> <td>98</td> <td>98</td> <td>98</td> <td>98</td> </tr> </tbody> </table>

  • QTableWidget signal cellChanged(): distinguish between user input and change by routines

    - by crabman
    i am using PyQt but my question is a general Qt one: I have a QTableWidget that is set up by the function updateTable. It writes the data from DATASET to the table when it is called. Unfortunately this causes my QTableWidget to emit the signal cellChanged() for every cell. The signal cellChanged() is connected to a function on_tableWidget_cellChanged that reads the contents of the changed cell and writes it back to DATASET. This is necessary to allow the user to change the data manually. So everytime the table is updated, its contents are written back to DATASET. Is there a way to distinguish if the cell was changed by the user or by updateTable? i thought of disconnecting on_tableWidget_cellChanged by updateTable temporarily but that seems to be a little dirty.

  • simple web parts in asp.net show as blank page

    - by Javaman59
    I am trying to develop web parts in VS 2008/WinXP I created a Web Site project, and added a couple of web parts within the default form in default.aspx <form id="form1" runat="server"> <div> <asp:WebPartManager ID="WebPartManager1" runat="server"> </asp:WebPartManager> <asp:WebPartZone ID="WebPartZone1" runat="server"> </asp:WebPartZone> </div> </form> When I first ran it (in the debugger), a popup told to me enable Windows authentication in IIS (so something is working!).

  • Ingredient Substitutes while Baking

    - by Rekha
    In our normal cooking, we substitute the vegetables for the gravies we prepare. When we start baking, we look for a good recipe. At least one or two ingredient will be missing. We do not know where to substitute what to bring same output. So we finally drop the plan of baking. Again after a month, we get the interest in baking. Again one or two lack of ingredient and that’s it. We keep on doing this for months. When I was going through the cooking blogs, I came across a site with the Ingredient Substitutes for Baking: (*) is to indicate that this substitution is ideal from personal experience. Flour Substitutes ( For 1 cup of Flour) All Purpose Flour 1/2 cup white cake flour plus 1/2 cup whole wheat flour 1 cup self-rising flour (omit using salt and baking powder if the recipe calls for it since self raising flour has it already) 1 cup plus 2 tablespoons cake flour 1/2 cup (75 grams) whole wheat flour 7/8 cup (130 grams) rice flour (starch) (do not replace all of the flour with the rice flour) 7/8 cup whole wheat Bread Flour 1 cup all purpose flour 1 cup all purpose flour plus 1 teaspoon wheat gluten (*) Cake Flour Place 2 tbsp cornstarch in 1 cup and fill the rest up with All Purpose flour (*) 1 cup all purpose flour minus 2 tablespoons Pastry flour Place 2 tbsp cornstarch in 1 cup and fill the rest up with All Purpose flour Equal parts of All purpose flour plus cake flour (*) Self-rising Flour 1½ teaspoons of baking powder plus ½ teaspoon of salt plus 1 cup of all-purpose flour. Cornstarch (1 tbsp) 2 tablespoons all-purpose flour 1 tablespoon arrowroot 4 teaspoons quick-cooking tapioca 1 tablespoon potato starch or rice starch or flour Tapioca (1 tbsp) 1 – 1/2 tablespoons all-purpose flour Cornmeal (stone ground) polenta OR corn flour (gives baked goods a lighter texture) if using cornmeal for breading,crush corn chips in a blender until they have the consistency of cornmeal. maize meal Corn grits Sweeteners ( for Every 1 cup ) * * (HV) denotes Healthy Version for low fat or fat free substitution in Baking Light Brown Sugar 2 tablespoons molasses plus 1 cup of white sugar Dark Brown Sugar 3 tablespoons molasses plus 1 cup of white sugar Confectioner’s/Powdered Sugar Process 1 cup sugar plus 1 tablespoon cornstarch Corn Syrup 1 cup sugar plus 1/4 cup water 1 cup Golden Syrup 1 cup honey (may be little sweeter) 1 cup molasses Golden Syrup Combine two parts light corn syrup plus one part molasses 1/2 cup honey plus 1/2 cup corn syrup 1 cup maple syrup 1 cup corn syrup Honey 1- 1/4 cups sugar plus 1/4 cup water 3/4 cup maple syrup plus 1/2 cup granulated sugar 3/4 cup corn syrup plus 1/2 cup granulated sugar 3/4 cup light molasses plus 1/2 cup granulated white sugar 1 1/4 cups granulated white or brown sugar plus 1/4 cup additional liquid in recipe plus 1/2 teaspoon cream of tartar Maple Syrup 1 cup honey,thinned with water or fruit juice like apple 3/4 cup corn syrup plus 1/4 cup butter 1 cup Brown Rice Syrup 1 cup Brown sugar (in case of cereals) 1 cup light molasses (on pancakes, cereals etc) 1 cup granulated sugar for every 3/4 cup of maple syrup and increase liquid in the recipe by 3 tbsp for every cup of sugar.If baking soda is used, decrease the amount by 1/4 teaspoon per cup of sugar substituted, since sugar is less acidic than maple syrup Molasses 1 cup honey 1 cup dark corn syrup 1 cup maple syrup 3/4 cup brown sugar warmed and dissolved in 1/4 cup of liquid ( use this if taste of molasses is important in the baked good) Cocoa Powder (Natural, Unsweetened) 3 tablespoons (20 grams) Dutch-processed cocoa plus 1/8 teaspoon cream of tartar, lemon juice or white vinegar 1 ounce (30 grams) unsweetened chocolate (reduce fat in recipe by 1 tablespoon) 3 tablespoons (20 grams) carob powder Semisweet baking chocolate (1 oz) 1 oz unsweetened baking chocolate plus 1 Tbsp sugar Unsweetened baking chocolate (1 oz ) 3 Tbsp baking cocoa plus 1 Tbsp vegetable oil or melted shortening or margarine Semisweet chocolate chips (1 cup) 6 oz semisweet baking chocolate, chopped (Alternatively) For 1 cup of Semi sweet chocolate chips you can use : 6 tablespoons unsweetened cocoa powder, 7 tablespoons sugar ,1/4 cup fat (butter or oil) Leaveners and Diary * * (HV) denotes Healthy Version for low fat or fat free substitution in Baking Compressed Yeast (1 cake) 1 envelope or 2 teaspoons active dry yeast 1 packet (1/4 ounce) Active Dry yeast 1 cake fresh compressed yeast 1 tablespoon fast-rising active yeast Baking Powder (1 tsp) 1/3 teaspoon baking soda plus 1/2 teaspoon cream of tartar 1/2 teaspoon baking soda plus 1/2 cup buttermilk or plain yogurt 1/4 teaspoon baking soda plus 1/3 cup molasses. When using the substitutions that include liquid, reduce other liquid in recipe accordingly Baking Soda(1 tsp) 3 tsp Baking Powder ( and reduce the acidic ingredients in the recipe. Ex Instead of buttermilk add milk) 1 tsp potassium bicarbonate Ideal substitution – 2 tsp Baking powder and omit salt in recipe Cream of tartar (1 tsp) 1 teaspoon white vinegar 1 tsp lemon juice Notes from What’s Cooking America – If cream of tartar is used along with baking soda in a cake or cookie recipe, omit both and use baking powder instead. If it calls for baking soda and cream of tarter, just use baking powder.Normally, when cream of tartar is used in a cookie, it is used together with baking soda. The two of them combined work like double-acting baking powder. When substituting for cream of tartar, you must also substitute for the baking soda. If your recipe calls for baking soda and cream of tarter, just use baking powder. One teaspoon baking powder is equivalent to 1/4 teaspoon baking soda plus 5/8 teaspoon cream of tartar. If there is additional baking soda that does not fit into the equation, simply add it to the batter. Buttermilk (1 cup) 1 tablespoon lemon juice or vinegar (white or cider) plus enough milk to make 1 cup (let stand 5-10 minutes) 1 cup plain or low fat yogurt 1 cup sour cream 1 cup water plus 1/4 cup buttermilk powder 1 cup milk plus 1 1/2 – 1 3/4 teaspoons cream of tartar Plain Yogurt (1 cup) 1 cup sour cream 1 cup buttermilk 1 cup crème fraiche 1 cup heavy whipping cream (35% butterfat) plus 1 tablespoon freshly squeezed lemon juice Whole Milk (1 cup) 1 cup fat free milk plus 1 tbsp unsaturated Oil like canola (HV) 1 cup low fat milk (HV) Heavy Cream (1 cup) 3/4 cup milk plus 1/3 cup melted butter.(whipping wont work) Sour Cream (1 cup) (pls refer also Substitutes for Fats in Baking below) 7/8 cup buttermilk or sour milk plus 3 tablespoons butter. 1 cup thickened yogurt plus 1 teaspoon baking soda. 3/4 cup sour milk plus 1/3 cup butter. 3/4 cup buttermilk plus 1/3 cup butter. Cooked sauces: 1 cup yogurt plus 1 tablespoon flour plus 2 teaspoons water. Cooked sauces: 1 cup evaporated milk plus 1 tablespoon vinegar or lemon juice. Let stand 5 minutes to thicken. Dips: 1 cup yogurt (drain through a cheesecloth-lined sieve for 30 minutes in the refrigerator for a thicker texture).

Lower fat: 1 can chilled evaporated milk whipped with 1 teaspoon lemon juice. 1 cup plain yogurt plus 1 tablespoon cornstarch 1 cup plain nonfat yogurt Substitutes for Fats in Baking * * (HV) denoted Healthy Version for low fat or fat free substitution in Baking Butter (1 cup) 1 cup trans-free vegetable shortening 3/4 cups of vegetable oil (example. Canola oil) Fruit purees (example- applesauce, pureed prunes, baby-food fruits). Add it along with some vegetable oil and reduce any other sweeteners needed in the recipe since fruit purees are already sweet. 1 cup polyunsaturated margarine (HV) 3/4 cup polyunsaturated oil like safflower oil (HV) 1 cup mild olive oil (not extra virgin)(HV) Note: Butter creates the flakiness and the richness which an oil/purees cant provide. If you don’t want to compromise that much to taste, replace half the butter with the substitutions. Shortening(1 cup) 1 cup polyunsaturated margarine like Earth Balance or Smart Balance(HV) 1 cup + 2tbsp Butter ( better tasting than shortening but more expensive and has cholesterol and a higher level of saturated fat; makes cookies less crunchy, bread crusts more crispy) 1 cup + 2 tbsp Margarine (better tasting than shortening but more expensive; makes cookies less crunchy, bread crusts tougher) 1 Cup – 2tbsp Lard (Has cholesterol and a higher level of saturated fat) Oil equal amount of apple sauce stiffly beaten egg whites into batter equal parts mashed banana equal parts yogurt prune puree grated raw zucchini or seeds removed if cooked.

Alternatively in another pan, place brown sugar and water and bring to a boil without stirring. Now mix both the sugars and simmer in low heat until they come together as one thick syrup. Remove from heat, add butter and the extract. Use this in place of maple syrup. Store it in a fridge in an air tight container.

  • Calling oracle stored procedure from Excel - VBA

    - by Ram
    I have to execute an Oracle stored procedure from vba (Excel) with around 38 input parameters. The stored procedure will insert some values in the destination table once that is executed. When it is executed through VBA the number of fields which is inserted is less than when it is executed directly from the backend (oracle). For example it is creating around 17 fields of records while executing directly from the back end. (I have created a wrapper class in the back-end and passing the same parameter values in the back-end.). It is creating around 15 fields of records while executing from the excel VBA in the destination table. Kindly let me know what could be the possible reasons for this.

  • DynamicQuery: How to select a column with linq query that takes parameters

    - by Richard77
    Hello, We want to set up a directory of all the organizations working with us. They are incredibly diverse (government, embassy, private companies, and organizations depending on them ). So, I've resolved to create 2 tables. Table 1 will treat all the organizations equally, i.e. it'll collect all the basic information (name, address, phone number, etc.). Table 2 will establish the hierarchy among all the organizations. For instance, Program for illiterate adults depends on the National Institute for Social Security which depends on the Labor Ministry. In the Hierarchy table, each column represents a level. So, for the example above, (i)Labor Ministry - Level1(column1), (ii)National Institute for Social Security - Level2(column2), (iii)Program for illiterate adults - Level3(column3). To attach an organization to an hierarchy, the user needs to go level by level(i.e. column by column). So, there will be at least 3 situations: If an adequate hierarchy exists for an organization(for instance, level1: US Embassy), that organization can be added (For instance, level2: USAID).-- US Embassy/USAID, and so on. How about if one or more levels are missing? - then they need to be added How about if the hierarchy need to be modified? -- not every thing need to be modified. I do not have any choice but working by level (i.e. column by column). I does not make sense to have all the levels in one form as the user need to navigate hierarchies to find the right one to attach an organization. Let's say, I have those queries in my repository (just that you get the idea). Query1 var orgHierarchy = (from orgH in db.Hierarchy select orgH.Level1).FirstOrDefault; Query2 var orgHierarchy = (from orgH in db.Hierarchy select orgH.Level2).FirstOrDefault; Query3, Query4, etc. The above queries are the same except for the property queried (level1, level2, level3, etc.) Question: Is there a general way of writing the above queries in one? So that the user can track an hierarchy level by level to attach an organization. In other words, not knowing in advance which column to query, I still need to be able to do so depending on some conditions. For instance, an organization X depends on Y. Knowing that Y is somewhere on the 3rd level, I'll go to the 4th level, linking X to Y. I need to select (not manually) a column with only one query that takes parameters. Thanks for helping

  • How to structure VB.NET windows forms applications

    - by Jon
    What is the best way to structure a VB.NET windows forms application so that code can be reused and the app can be extended easily. I used to create lots of new forms. This lead to lots of repeated code and forms which did similar things. Now, for forms which do similar jobs, such as view/edit/delete items from a specific db table, I create a form with the required controls, have the form create an instance of a class with params such as a collection of the controls and a string containing the db table name. Then the individual controls call functions of the class. Advanced forms will inherit and extend this basic form class. 1) Has there already been work done in this area? 2) Are there books / articles available which discuss the options available on this topic? Thanks!

  • One to many too much data returned - MySQL

    - by Evan McPeters
    I have 2 related MySQL tables in a one to many relationship. Customers: cust_id, cust_name, cust_notes Orders: order_id, cust_id, order_comments So, if I do a standard join to get all customers and their orders via PHP, I return something like: Jack Black, jack's notes, comments about jack's 1st order Jack Black, jack's notes, comments about jack's 2nd order Simon Smith, simon's notes, comments about simon's 1st order Simon Smith, simon's notes, comments about simon's 2nd order The problem is that *cust_notes* is a text field and can be quite large (a couple of thousand words). So, it seems like returning that field for every order is inneficient. I could use *GROUP_CONCAT* and JOINS to return all *order_comments* on a single row BUT order_comments is a large text field too, so it seems like that could create a problem. Should I just use two separate queries, one for the customers table and one for the orders table? Is there a better way?

  • What is the most simple implementation of IDynamicMetaObjectProvider?

    - by Néstor Sánchez A.
    Hi, I have this scenario... 1.- I'm providing a "Dynamic Table" for wich users can define Fields. Each Dynamic Table will have as many rows/records as needed, but the Field definitions are centralized. 2.- My Dynamic Row/Record class was inherited from the .NET DLR DynamicObject class, and the underlying storage was a List appropriately associated to the defining fields. Everything works fine! BUT... 3.- Because I need to Serialize the content, and DynamicObject is not Serializable, I was forced to generate and carry a Dynamic Object when dynamic member access is required. But this is ugly and redundant. So, I need to implement IDynamicMetaObjectProvider myself to achieve dynamic access and serialization together. After googling/binging unsuccessfully I ask for your help... Can anybody please give a good example (or related link) for doing that?

  • Does Entity Framework 4 not support property automatic lazy loading for model-first entities?

    - by KallDrexx
    All references that I find for lazy loading say it's possible but they all mention POCOs and that's it. I am using EF4 with the model-first methodology. In my model diagram I have a Project table and a UserObject table, with a 1 to many relationship between them. However, in code, when I have a valid UserObject and I attempt to get the project performing: Project prj = userobj.Project. Unfortunately, this doesn't work as it claims that UserObject.Project is null. It seems like I have to explicitly load the Project object via calling UserObject.ProjectReference.Load() prior to calling .Project. Is there any way for this to occur automatically when I access the .Project property?

  • US Bank Routing Number and BIC/SWIFT

    - by Konerak
    I know it is a bit offtopic, but I've been having a hard time finding more information to this question, and since this site is visited by a lot of people from the United States, you guys might know/find the answer more easily. Banks in europe each have a SWIFT Number, while US Banks use Routing Numbers. This leads to following questions: Does each bank in the US also carry a BIC number? (SWIFT) Is there a 1-1 relationship between BIC/SWIFT and Routing Numbers? Is there a list of these numbers somewhere? Background information: We're adding international payments to our bookkeeping application. Users can add international suppliers, but my boss prefered not to change the current supplier table but to have the ROUTING NUMBER in another table, with as PK the BIC. I'm wondering if BIC is a valid choice, or if it should just be BANK ACCOUNT NUMBER.

  • SyncFramework upgrade from 1.0 to 2.0 Sql Server CE database change tracking issue

    - by Andronicus
    I'm trying to upgrade an application that uses Sync Framework 1.0 to synchronise a SqlServerCe database with SqlServer 2005. On the client, the existing database already has change tracking enabled, but when the sync is initiated SyncFramework 2.0 fails to find the last Sync Received anchor and then tries to re=initialize the Change tracking, which fails. I get the exception... {System.Exception} = {"The specified change tracking operation is not supported. To carry out this operation on the table, disable the change tracking on the table, and enable the change tracking."} It seems like all I can do is delete the local database and recreate it. Which is not a great solution for us, since some of the data in the clients database is not synced with the server, and our users would prefer not to loose this data in the upgrade. Is there any reason why SyncFramework 2.0 cannot locate the existing Last received sync anchor?

  • Best way to display a list of events by month

    - by EmmyS
    I have a mySQL table of events and want to display them in a list using PHP. Pretty simple, except I only want to display the month name once, for example: May 2010 12th, 7 pm. Event 1 - event one description 15th, 5:30 pm. Event 2 - event two description June 2010 9th, 7 pm. Event 1 - event one description 11th, 5:30 pm. Event 2 - event two description I'm very new at SQL and PHP. I can think of one way to do it. It would involve selecting all records grouped by date, then looping through all records, comparing the month/year value each time and the first time the month/year doesn't match, print a new header row to my HTML table. I can't believe it's the best or most efficient way to go. Any ideas for a newbie? I'm sure my way would work, but it's inelegant at best, and processor-intensive at worst.

  • Article search engine in php

    - by Jason
    Hello, I am using sphinx as a search engine on my website its working perfect and I have no complain with it. The only thing it lacks is, it does not allow me to search articles whose query length is more than 15 words. I know in reality people don't use more than 3-4 words i want to use it for finding duplicate contents. I was wondering if there is any alternative solution to sphinx. I want to cope with duplicate contents. My main articles table is in innodb but I am also caching articles into MyISAM table as well for full text searching but when I search an article it takes ages to perform one search. Its not the query problem, i think mysql lacks the fulltext searching facility. Thanks Jason

  • SQL's Rownumber with Linq-to-entities

    - by mariki
    I am converting my project to use EF and also want to covert stored procedures into Linq-to-entities queries. This my SQL query (simple version) that I have trouble to convert: SELECT CategoryID, Title as CategoryTitle,Description, LastProductTitle,LastProductAddedDate FROM ( SELECT C.CategoryID, C.Title,C.Description, C.Section, P.Title as LastProductTitle, P.AddedDate as LastProductAddedDate, ROW_NUMBER() OVER (PARTITION BY P.CategoryID ORDER BY P.AddedDate DESC) AS Num FROM Categories C LEFT JOIN Products P ON P.CategoryID = C.CategoryID ) OuterSelect WHERE OuterSelect.Num = 1 In words: I want to return all Categories (from Categories table) and title and date of addition of the product (from Products table) that was added last to this category. How can I achieve this using Entity frame work query? In most efficient way.

  • Slow select when inserting large amounts of data (MYSQL)

    - by siannopollo
    I have a process that imports a lot of data (950k rows) using inserts that insert 500 rows at a time. The process generally takes about 12 hours, which isn't too bad. Normally doing a query on the table is pretty quick (under 1 second) as I've put (what I think to be) the proper indexes in place. The problem I'm having is trying to run a query when the import process is running. It is making the query take almost 2 minutes! What can I do to make these two things not compete for resources (or whatever)? I've looked into "insert delayed" but not sure I want to change the table to MyISAM. Thanks for any help!

  • Application with two UITabBarControls

    - by kovpas
    Hello, I want to create an app, whith the following structure: UITabBarController ..UINavigationController ....UITabBarController So, in other words, I want to load first UITabbarController as my main ViewController, that appears on application start, in its' first tab there's a UINavigationController with a table, which shows another UITabBarController by pressing on a table cell. I started Tab Based application, set first tab to UINavigationController, and its ViewController to my TableViewController. I also created second UITabBarController in Interface Builder. Created a separate class for this controller. Everything works fine at start - my first UITabBarController is shown perfectly, but when I'm trying to push my second UITabBarController, using my UINavigationController, it looks like nothing is loaded from a .xib file - there are just an empty TabBar and NavigationBar pushed. Seems, that something is wrong with an architecture, but I can't figure out the problem. Thanks in advance and I'm sorry for my poor English. Please let me know if something is not clear, I'll try to rephrase it :).

  • No scrolling occurs when UITableView scrollToRowAtIndexPath is invoked

    - by theactiveactor
    My view contains a simple TableView with 6 rows and a button that invokes doScroll when clicked. My objective for doScroll() is simply scroll to the 5th cell such that it's at top of the table view. - (void)doScroll: (id)sender { NSIndexPath *index = [NSIndexPath indexPathForRow:4 inSection: 1]; [m_tableView scrollToRowAtIndexPath:index atScrollPosition:UITableViewScrollPositionTop animated:YES]; } However when doScroll is invoked, the tableview scrolls only slightly. I suspect this has something to do with the size of the scroll view. So I tried increasing the height of m_tableview.contentsize before scrolling. After I do this however, no scrolling occurs at all... The view controller is a simple UIViewController and refers to the table view via IBOutlet. For some reason, scrolling works as expected for the default Navigation Based Application, where the controller is a UITableViewController

  • Using MongoDB with Ruby On Rails and the Mongomapper plugin

    - by Micke
    Hello, i am currently trying to learn Ruby On Rails as i am a long-time PHP developer so i am building my own community like page. I have came pritty far and have made the user models and suchs using MySQL. But then i heard of MongoDB and looked in to it a little bit more and i find it kinda nice. So i have set it up and i am using mongomapper for the connection between rails and MongoDB. And i am now using it for the News page on the site. I also have a profile page for every User which includes their own guestbook so other users can come to their profile and write a little message to them. My thought now is to change the User models from using MySQL to start using MongoDB. I can start by showing how the models for each User is set up. The user model: class User < ActiveRecord::Base has_one :guestbook, :class_name => "User::Guestbook" The Guestbook model model: class User::Guestbook < ActiveRecord::Base belongs_to :user has_many :posts, :class_name => "User::Guestbook::Posts", :foreign_key => "user_id" And then the Guestbook posts model: class User::Guestbook::Posts < ActiveRecord::Base belongs_to :guestbook, :class_name => "User::Guestbook" I have divided it like this for my own convenience but now when i am going to try to migrate to MongoDB i dont know how to make the tables. I would like to have one table for each user and in that table a "column" for all the guestbook entries since MongoDB can have a EmbeddedDocument. I would like to do this so i just have one Table for each user and not like now when i have three tables just to be able to have a guestbook. So my thought is to have it like this: The user model: class User include MongoMapper::Document one :guestbook, :class_name => "User::Guestbook" The Guestbook model model: class User::Guestbook include MongoMapper::EmbeddedDocument belongs_to :user many :posts, :class_name => "User::Guestbook::Posts", :foreign_key => "user_id" And then the Guestbook posts model: class User::Guestbook::Posts include MongoMapper::EmbeddedDocument belongs_to :guestbook, :class_name => "User::Guestbook" But then i can think of one problem.. That when i just want to fetch the user information like a nickname and a birthdate then it will have to fetch all the users guestbook posts. And if each user has like a thousand posts in the guestbook it will get really much to fetch for the system. Or am i wrong? Do you think i should do it any other way? Thanks in advance and sorry if i am hard to understand but i am not so educated in the english language :)

  • getting rid of filesort on WordPress MySQL query

    - by Hans
    An instance of WordPress that I manage goes down about once a day due to this monster MySQL query taking far too long: SELECT SQL_CALC_FOUND_ROWS distinct wp_posts.* FROM wp_posts LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) LEFT JOIN wp_term_taxonomy ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id LEFT JOIN wp_ec3_schedule ec3_sch ON ec3_sch.post_id=id WHERE 1=1 AND wp_posts.ID NOT IN ( SELECT tr.object_id FROM wp_term_relationships AS tr INNER JOIN wp_term_taxonomy AS tt ON tr.term_taxonomy_id = tt.term_taxonomy_id WHERE tt.taxonomy = 'category' AND tt.term_id IN ('1050') ) AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish') AND NOT EXISTS (SELECT * FROM wp_term_relationships JOIN wp_term_taxonomy ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id WHERE wp_term_relationships.object_id = wp_posts.ID AND wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id IN (533,3567) ) AND ec3_sch.post_id IS NULL GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 10; What do I have to do to get rid of the very slow filesort?

  • Time and date dimension in data warehouse

    - by peperg
    I'm buildind an data warehouse. Each fact has it's timestamp. I need to create reports by day, month, quater but by hours too. Loking at the examples I see that dates tend to be saved in dimension tabels. But I think, that it makes no sense for time. The dimension table would grow and grow. On the other hand JOIN with date dimension table is more efficent than using date/time functions in SQL. What are your opinions/solutions ? (I'm using Infobright)
