• Creating 'select' listboxes using FormHelper in CakePHP

  - by joec

  I have two models Category and Point. The associations are defined as: Category hasMany Point Point belongsTo Category I would like, when adding Points to my database, to be able to select the category it belongs to from a <select> box, along with the rest of the form data. Where would i need to set the category list and how could i do it? And how would i produce the select box? I assume it could be done with $form->input('categorieslist',array('type'=>'select')); //categorieslist needs //setting somewhere. But i am fairly new to Cake and not done much with associations before. Thanks.

• Mysql advanced SELECT, or multiple SELECTS? Movies keywords

  - by Supyxy

  I have a mysql database with movies as follows: MOVIES(id,title) KEYWORDS_TABLE(id,key_id) [id is referenced to movies.id, key_id is refernced to keywords.id] KEYWORDS(id,keyword) //this doesn't matter on my example.. Basically i have movies with their titles and plot keywords for each one, i want to select all movies that have the same keywords with with a given movie id. I tried something like: SELECT key_id FROM keywords_table WHERE id=9 doing that in php and storing all the IDs in an array $key_id.. then i build another select that looks like: SELECT movies.title FROM movies,keywords_table WHERE keywords_table.key_id=$key_id[1] OR keywords_table.key_id=$key_id[2] OR ......... OR keywords_table.key_id=$key_id[n] This kinda works but it takes too much time as we talk about a database with thousands of thousands of records. So, any suggestions?? thanks!

• jQuery carousel clicks update <select> list's "selected" option to match clicked item's title attrib

  - by Scott B

  The code below allows me to change a preview image outside the carousel widget so that it matches the element under the mouse. For example, if the user mouses over image2's thumbnail, the script updates .selectedImage so that it displays image2's full size version. I'd like to enhance it so that the #myThumbs options listing updates its "selected" option to match the carousel image that receives a click. Mouseover changes the preview image and click changes the select list to match the same name. The items in the carousel will have the same title attribute as the items in the select list, so I would expect that I can pass that value from the carousel to the select list. $(function() { $("#carousel").jCarouselLite({ btnNext: ".next", btnPrev: ".prev", visible: 6, mouseWheel: true, speed: 700 }); $('#carousel').show(); $('#carousel ul li').hover(function(e) { var img_src = $(this).children('img').attr('src'); $('.selectedImage img').attr('src',img_src); } ,function() { $('.selectedImage img').attr('src', '<?php echo $selectedThumb; ?>');}); }); <select id="myThumbs"> <option>image1</option> <option selected="selected">image2</option> <option>image3</option> </select>

• MSSQL: Views that use SELECT * need to be recreated if the underlying table changes

  - by cbp

  Is there a way to make views that use SELECT * stay in sync with the underlying table. What I have discovered is that if changes are made to the underlying table, from which all columns are to be selected, the view needs to be 'recreated'. This can be achieved simly by running an ALTER VIEW statement. However this can lead to some pretty dangerous situations. If you forgot to recreate the view, it will not be returning the correct data. In fact it can be returning seriously messed up data - with the names of the columns all wrong and out of order. Nothing will pick up that the view is wrong unless you happened to have it covered by a test, or a data integrity check fails. For example, Red Gate SQL Compare doesn't pick up the fact that the view needs to be recreated. To replicate the problem, try these statements: CREATE TABLE Foobar (Bar varchar(20)) CREATE VIEW v_Foobar AS SELECT * FROM Foobar INSERT INTO Foobar (Bar) VALUES ('Hi there') SELECT * FROM v_Foobar ALTER TABLE Foobar ADD Baz varchar(20) SELECT * FROM v_Foobar DROP VIEW v_Foobar DROP TABLE Foobar I am tempted to stop using SELECT * in views, which will be a PITA. Is there a setting somewhere perhaps that could fix this behaviour?

• Selecting an item in an HTML SELECT list using keyboard doesnt trigger the CLICK event

  - by Jimbo

  I have an HTML select list which, when an item is selected, must show different information beneath it. The onclick or JQuery change events are triggered when a select list item is selected by being clicked on (mouse), but not when the user uses key presses (keyboard). Any idea what event to watch in order to determine when the selected list item has changed? Here is a BASIC test example: <select id="mylist" name="mylist"> <option value="">(none)</option> <option value="1">Test 1</option> <option value="2">Test 2</option> <option value="3">Test 3</option> </select> <span id="myspan"></span> <script type="text/javascript"> $("#mylist").change(function() { $("#myspan").html($("#mylist").attr("selectedIndex")); }); </script>

• Select calls seems to not time out.

  - by martsbradley

  HI Folks, I have a threaded C++ program where up to three threads are calling select on a three separate socket descriptors waiting for data to become available. Each thread handles one socket and adds it to the readfds with a timeout of 300 seconds. After select returns if there is data available I'm calling recv to read it. Is there anything that I need to be aware of with winsock and threads because for some reason after a number of hours the select calls all seem to be not timing out. Can a multi threaded program select from a number of threads without issue? I know that I should have one thread listening to all three sockets however that would be a large change for this app and I'm only looking to apply a bug fix. cheers, Martin.

  I'm using LINQ2SQL and I want to compare two tables and select all rows that are missing from one tables (based upon one of the column values). In standard SQL I would write this as: SELECT FirstName, LastName, RefId, Email FROM Users_ActiveDirectory AS ADU WHERE NOT EXISTS ( SELECT U.RefId FROM Users AS U WHERE U.RefID = ADU.RefId ) However I'm not sure how to achieve the same result using LINQ2SQL?

• Defining a select list through controller and view model

  - by Ibrar Hussain

  I have a View Model that looks like this: public class SomeViewModel { public SomeViewModel(IEnumerable<SelectListItem> orderTemplatesListItems) { OrderTemplateListItems = orderTemplatesListItems; } public IEnumerable<SelectListItem> OrderTemplateListItems { get; set; } } I then have an Action in my Controller that does this: public ActionResult Index() { var items = _repository.GetTemplates(); var selectList = items.Select(i => new SelectListItem { Text = i.Name, Value = i.Id.ToString() }).ToList(); var viewModel = new SomeViewModel { OrderTemplateListItems = selectList }; return View(viewModel); } Lastly my view: @Html.DropDownListFor(n => n.OrderTemplateListItems, new SelectList(Model.OrderTemplateListItems, "value", "text"), "Please select an order template") The code works fine and my select list populates wonderfully. Next thing I need to do is set the selected value that will come from a Session["orderTemplateId"] which is set when the user selects a particular option from the list. Now after looking online the fourth parameter should allow me to set a selected value, so if I do this: @Html.DropDownListFor(n => n.OrderTemplateListItems, new SelectList(Model.OrderTemplateListItems, "value", "text", 56), "Please select an order template") 56 is the Id of the item that I want selected, but to no avail. I then thought why not do it in the Controller? As a final attempt I tried building up my select list items in my Controller and then passing the items into the View: public ActionResult Index() { var items = _repository.GetTemplates(); var orderTemplatesList = new List<SelectListItem>(); foreach (var item in items) { if (Session["orderTemplateId"] != null) { if (item.Id.ToString() == Session["orderTemplateId"].ToString()) { orderTemplatesList.Add(new SelectListItem { Text = item.Name, Value = item.Id.ToString(), Selected = true }); } else { orderTemplatesList.Add(new SelectListItem { Text = item.Name, Value = item.Id.ToString() }); } } else { orderTemplatesList.Add(new SelectListItem { Text = item.Name, Value = item.Id.ToString() }); } } var viewModel = new SomeViewModel { OrderTemplateListItems = orderTemplatesList }; return View(viewModel); } Leaving my View like so: @Html.DropDownListFor(n => n.OrderTemplateListItems, new SelectList(Model.OrderTemplateListItems, "value", "text"), "Please select an order template") Nothing! Why isn't this working for me?

• What is the reason not to use select * ?

  - by Chris Lively

  I've seen a number of people claim that you should specifically name each column you want in your select query. Assuming I'm going to use all of the columns anyway, why would I not use SELECT *? Even considering the question from 9/24, I don't think this is an exact duplicate as I'm approaching the issue from a slightly different perspective. One of our principles is to not optimize before it's time. With that in mind, it seems like using SELECT * should be the preferred method until it is proven to be a resource issue or the schema is pretty much set in stone. Which, as we know, won't occur until development is completely done. That said, is there an overriding issue to not use SELECT *?
