• Mapping multiple keys to the same value in a Javascript hash

  - by Bears will eat you

  I use a Javascript hash object to store a set of numerical counters, set up like this [this is greatly simplified]: var myHash = { A: 0, B: 0, C: 0 }; Is there a way to make other keys, ones not explicitly in myHash, map to keys that are? For instance, I'd like [again, this is simplified]: myHash['A_prime']++; // or myHash.A_prime++; to be exactly equivalent to myHash['A']++; // or myHash.A++; e.g. incrementing the value found at the key A, not A_prime.

• Jquery autocomplete UI - No results on multiple fields

  - by pjammer

  Andrew's answer to my comment has sparked this question. According to his awesome answer in the link above, the code at the bottom of the question will only work for ONE widget. But it's killer nice code and makes sense... I guess I want the best of both worlds. Nice JS, (if that is possible) and to have the zero results show() just the element that we're using at the time. This code snippet is the main crux of my problem, as I see it: source: function (request, response) { jQuery.ajax({ url: "/autocomplete.json", data: { term: request.term }, success: function (data) { if (data.length == 0) { jQuery('span.guest_investor_email').show(); jQuery('span.investor_field_delete_button').show(); } response(data); } }); Currently: I have a button on my page that says "Add more Information" and each time you click it, a new instance of the autocomplete text field appears, complete with some hidden fields and a display:none; on guest_investor_email. If I use the autocomplete text field, say 3 times, and i have 3 autocomplete instances on the page and the third one finds 0 results: The code will show() all 3 instances of the guest_investor_email text field, instead of just this one that is blank. QUESTION: How do i get something like jQuery(this).siblings(('span.guest_investor_email').show(); to work? this is an Object and not an array of elements to select. If it isn't with this I don't mind, as long as I know how to get at it. Thanks. Full Code: jQuery(".auto_search_complete").live("click", function() { jQuery(this).autocomplete({ minLength: 3, source: function (request, response) { jQuery.ajax({ url: "/autocomplete.json", data: { term: request.term }, success: function (data) { if (data.length == 0) { jQuery('span.guest_investor_email').show(); jQuery('span.investor_field_delete_button').show(); } response(data); } }); }, focus: function(event, ui) { jQuery(this).val(ui.item.user ? ui.item.user.name : ui.item.pitch.name); return false; }, select: function(event, ui) { jQuery(this).val(ui.item.user ? ui.item.user.name : ui.item.pitch.name); jQuery(this).siblings('div.hidden_fields').children('.poly_id').val(ui.item.user ? ui.item.user.id : ui.item.pitch.id); jQuery(this).siblings('div.hidden_fields').children('.poly_type').val(ui.item.user ? "User" : "Pitch"); jQuery(this).siblings('span.guest_investor_email').hide(); jQuery(this).siblings('span.investor_field_delete_button').show(); jQuery(this).attr('readonly','readonly'); jQuery(this).attr('id', "investor-selected"); return false; } }).each(function() { jQuery(this).data( "autocomplete" )._renderItem = function( ul, item ) { return jQuery( "" ) .data( "item.autocomplete", item ) .append("" + (item.user ? item.user.name : item.pitch.name) + "" + (item.user ? item.user.investor_type : item.pitch.investor_type) + " - " + (item.user ? item.user.city : item.pitch.city) + "" ) .appendTo( ul ); }; }); });

• Checking multiple conditions in Ruby (within Rails, which may not matter)

  - by Ev

  Hello rubyists and railers, I have a method which checks over a params hash to make sure that it contains certain keys, and to make sure that certain values are set within a certain range. This is for an action that responds to a POST query by an iPhone app. Anyway, this method is checking for about 10 different conditions - any of which will result in an HTTP error being returned (I'm still considering this, but possibly a 400: bad request error). My current syntax is basically this (paraphrased): def invalid_submission_params?(params) [check one] or [check two] or [check three] or [check four] etc etc end Where each of the check statements returns true if that particular parameter check results in an invalid parameter set. I call it as a before filter with params[:submission] as the argument. This seems a little ugly (all the strung together or statements). Is there a better way? I have tried using case but can't see a way to make it more elegant. Or, perhaps, is there a rails method that lets me check the incoming params hash for certain conditions before handing control off to my action method?

• DDD and Entity Base, Model using multiple identity types

  - by Thomas

  I have a model that looks like this: public interface IEntity { int Id { get; set; } } Then the idea is to have my entities inherit from this interface: public class User : IEntity { public int Id { get; set; } } However, one of my entities actually has a Guid as an identifier. public class UserSession { public Guid Id { get; set; } } I really would like all my entities inheriting from the same interface but that would force me to add an integer based identity column to the UserSession which is unnecessary since Guid is the identity, but it would keep the domain model nice since all entities would inherit from the same base. What options do I have in this scenario? Can I have two base interfaces, one for int and one for Guid? Should I add an identity column into the UserSession entity although it is unnecessary? I need the Guid so I can't just get rid of it and replace it with and integer. Any thoughts on best practices?

• Multiple Keybinding to a single command

  My window has just a listview. This facilitates the users to incremental search the db. Since the design does not have a textbox, i've to globally handle the keys. I think it could be achieved by keybinding. But how can i handle all the keys and associate it to a single command. Also suggest me other methods if any.

• Using one data source across multiple views in Kendo UI SPA

  - by user3731783

  I am trying to build a Kendo UI SPA. I have two views. View 1 (appListView) shows Application Details in a grid and view 2 (activityView) will have a dropdown for application names and a grid that shows the activity for selected application As I am loading all the application details on the loading of view 1, I would like to re-use those details to populate the dropdown on view 2. Please see my code below. Everything works fine but when I go to View 2 it makes a call to the service again to get application details. I would like to use the existing data if it is already loaded and if the uses comes to view 2 directly then it should get application data also. I am not sure what I am missing in the code. View Markup: <script id="appListView" type="text/x-kendo-template"> <h3 data-bind="html: displayName"></h3> <div data-role="grid" data-editable="{'mode':'popup'}" data-bind="source: items" data-columns="[ {'field': 'Name'}, {'field': 'ContactEmail','title':'Contact Email'} ]"> </div> </script> <script id="" type="text\x-kendo-template"> <div> Activity for Application&nbsp;&nbsp; <input name="AppName" data-role="dropdownlist" data-source="appsModel.items" data-text-field="Name" data-value-field="Id" data-option-label="Choose an application name" style="width:250px;" /> </div> <div id="Activities" data-role="grid" data-bind="source: items" data-auto-bind="false" data-columns="[ {'field': 'Domain','title':'Domain'}, {'field': 'ActivityType','title':'Activity Type'} ]"> </div> </script> js with DataSource and View Model: //data sources var applications = new kendo.data.DataSource({ schema: { model: { id: "Id" } }, serverFiltering : true, transport: { read: { url: '/api/App', dataType: 'json', type:'GET' } } }); var activities = new kendo.data.DataSource({ schema: { model: { id: "Id" } }, transport: { read: { url: '/api/Activity', dataType: 'json', type: 'GET' }, parameterMap: function (data, type) { if (type == "read") { return 'appId=' + $("#AppName").val() ; } } } }); //Models var appsModel = kendo.observable({ items: applications, displayName: 'My Applications' }); var activityModel = kendo.observable({ items: activities, onAppChange: function(t){ $("#Activities").data("kendoGrid").dataSource.read(); }, dispayName: 'Application Activities' }); //views var layout = new kendo.Layout("layout-template"); var appListView = new kendo.View("appListView", { model: appsModel }); var activityView = new kendo.View("activityView", { model: activityModel }); Thank you for taking time to read this long question.

• UISwitch quick toggle multiple times.

  - by Tejaswi Yerukalapudi

  I was playing around my app and I was toggling a UISwitch really fast (who can resist?). So, I toggled it really fast for 10-15 times, an array that should contain the data from the table view cell that I have my switch in either has extra copies of the same cell sometimes, just one copy (the correct case) a few times and no data in it at all some times. The app works fine if it's toggled at normal speed. I'm pretty sure this scenario won't really happen with my users, but I'm still curious as to why it's happening. Thanks, Teja

  I have a service which is defined as ConcurrencyMode.Single: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, UseSynchronizationContext = false, InstanceContextMode = InstanceContextMode.PerSession, IncludeExceptionDetailInFaults = true)] public class MyService : IMyService This service provides a method to tell the client what it's currently working on: [OperationContract] string GetCurrentTaskDescription(); Is there a way to make this particular method allowable while another long-running task is running where all other methods still follow the single-threaded concurrency model?

• js regex replace multiple words

  - by Raghav

  I need to replace ${conferance name} with ABC, ${conference day} with Monday in the following sentence. Could some one help me with the regex. var text = "<td>${conference name}</td><td>${conference day}</td>" var list = ["${conferance name}", "${conference day}" ] for (var j = 1; j < list.length; j++) { //Extracting the col name var colName = list[j].split("${"); colName = colName.split("}")[0]; //Replacing the col name text = text.replace(new RegExp('\\$\\{' + colName + '\\}', 'g'), "ABC"); } The above code repalces fine if i have ${conference_name}, but it fails when i have a space in between. The list is a dynamic array. And the Replace statements are also dynamic. I just simulated them as objects here for fitting them in the Regex Statement. Thanks in Advance.

• Powershell GUI: Adding multiple instances of .tooltipseperate to menu

  - by obious

  So, I'm having a problem whereby for some reason I can only add one instance of a .tooltipseperator to a drop down menu. E.g. I have to create a new .tooltipseperator if I want to add another to a different menu list. I have this: $seperator = new-object System.Windows.Forms.Toolstripseparator $seperator1 = new-object System.Windows.Forms.Toolstripseparator which correlates to this: [Void]$packages_menu_bar.DropDownItems.Add($seperator1) [Void]$packages_menu_bar.DropDownItems.Add($Remove_from_AD) [Void]$process.DropDownItems.Add($Kill_process) [Void]$process.DropDownItems.Add($seperator) My question is this: how can I add the same instance on a .tooltipseperater to different menu items? Some sort of array? Thanks

• Assign multiple Emacs keybindings to a single command?

  - by Dan

  I'm giving ErgoEmacs mode a try to see if I can use Emacs more comfortably. Some of its keybindings are fairly intuitive, but in many cases I don't want to outright replace the defaults. For example, in the context of ErgoEmacs' navigation shortcut structure, M-h makes sense as a replacement for C-a--but I want to be able to use both, not just M-h. I tried simply duplicating the commands: ;; Move to beginning/ending of line (defconst ergoemacs-move-beginning-of-line-key (kbd "C-a")) ; original (defconst ergoemacs-move-end-of-line-key (kbd "C-e")) ; original (defconst ergoemacs-move-beginning-of-line-key (kbd "M-h")) ; ergoemacs (defconst ergoemacs-move-end-of-line-key (kbd "M-H")) ; ergoemacs But Emacs simply overwrites the first keybinding with the second. What's the best way to address this?

• [R] multiple functions in one R script

  - by Philipp

  Hi, I guess it's a stupid question, but I don't get it :-( I wrote an R script, which creates heatmaps out of xls files. I am calling this R script with a Perl system call and pass over all the arguments. This all works fine. Now I wanted to make the R script less confusing by writing different functions in the R script, for example: args <- commandArgs(TRUE) parsexls <- function(filepath) { data <- read.xls(...) assign("data", data, globalenv()) } reorder <- function(var) { data <- data[order...] assign("data", data, globalenv()) } When I want to call the functions with parsexls(args[1]) reorder(args[2]) nothing happens. But when I place the parsexls(args[1]) in the script between the two functions shown above, the file is parsed correctly! The reorder(args[2]) seems never to be read. Any ideas what I am doing wrong?

• Multiple children in single form in rails

  - by CaptnCraig

  I have a model that has an arbitrary number of children entities. For simplicity lets call the entities Orders and Items. I would like to have a create Orders form where I input the order information, as well as add as many items as I want. If I click the "Add another item" button, a new set of form elements will be added to input the new data, amounts, etc.. I could hack this out in pure javascript, but I'm pretty sure there has to be a more magical, railsish way to do it, maybe with a partial view or something. I'm just a little too new to rails to know what it is. What is the best way to dynamically add the new form elements, and then to access them in the create controller?

• 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!

• SQL Filter Multiple Tables Data

  - by Brad

  If it matters, I'm using Firebird 2.1 database. I have three tables, one with keywords, one with negative keywords, and the other with required keywords. I need to be able to filter the data so the output has just the keywords that meat the stipulation of not being in the negative keyword list, and IF there are any required words, then it will require the results to have those keywords in the end result. The tables are very similar, the field in the tables that I would be matching against are all called keyword. I don't know SQL very well at all. I'm guessing it would be something like SELECT keyword from keywordstable where keyword in requiredkeywordstable and where NOT in negativekeywordstable Just a side note, The required keywords table could be empty which would mean there are no required keywords. Any help would be appreciated. -Brad

• creational pattern for instances depending on multiple subclass instances

  I have a problem, for that I was not able to identify a suitable design pattern. I want to create instances depending on a given type that has been passed to a factory method. What I am doing until now is the following: T create(SuperType x) { if (x instanceof SubType1) { // do some stuff and return a new SubType extends T } else if (x instanceof SubType2) { // do some stuff and return a new SubType extends T } else if ... } else { throw new UnSupportedOperationException("nothing defined for " + x); } } It seems not to be best pratice for me. Has anybody an idea how to solve this in a better way?

• Vertically Merge Multiple Tables in MySQL by Joint Primary Key

  - by world

  Hello, I'll attempt to make my question as clear as possible. I'm fairly unexperienced with SQL, only know the really basic queries. In order to have a better idea I'd been reading the MySQL manual for the past few days, but I couldn't really find a concrete solution and my needs are quite specific. I've got 3 MySQL MyISAM tables: table1, table2 and table3. Each table has an ID column (ID, ID2, ID3 respectively), and different data columns. For example table1 has [ID, Name, Birthday, Status, ...] columns, table2 has [ID2, Country, Zip, ...], table3 has [ID3, Source, Phone, ...] you get the idea. The ID, ID2, ID3 columns are common to all three tables... if there's an ID value in table1 it will also appear in table2 and table3. The number of rows in these tables is identical, about 10m rows in each table. What I'd like to do is create a new table that contains (most of) the columns of all three tables and merge them into it. The dates, for instance, must be converted because right now they're in VARCHAR YYYYMMDD format. Reading the MySQL manual I figured STR_TO_DATE() would do the job, but I don't know how to write the query itself in the first place so I have no idea how to integrate the date conversion. So basically, after I create the new table (which I do know how to do), how can I merge the three tables into it, integrating into the query the date conversion?
