• Marionette multi user/roles application

  - by Fabrizio Fortino

  I have to build a pretty complex application using Backbone Marionette. The user interface has to handle multiple users with different roles. For example the 'admin' user will see the complete menu whereas the 'guest' user will access a subset of the same menu. Moreover some views will be accessible to all the users but the functions inside them (add, edit, delete) need to be profiled on the different roles. I am not sure about the right approach to use in order to solve this issue. I could have different templates for the different roles but in this case plenty of code will be duplicated inside them. Is there any best practice (or maybe some example) to sort my problem out using Marionette? Thanks in advance, Fabrizio

• Batch update records in Grails

  - by UltraVi01

  I have to calculate a "total" for each user based on individual actions -- that is, a User hasMany Actions and each Action has a point. So I need to basically get a sum of all the points on all the actions. Actions are added and subtracted regularly. Since this can be a rather heavy operation, it's not feasible that I execute the "total" each time I need it. Therefore, I am thinking of running the operation once a day for each user and storing the total points on the User as an int. Because I have thousands of users, I am trying to figure out the best way to do this. Should I basically iterate through all the users and call User.save() each time, or is there some kind of batch update mechanism I can use in Grails / GORM?

• SQL Access INSERT INTO Autonumber Field

  - by KrazyKash

  I'm trying to make a visual basic application which is connected to a Microsoft Access Database using OLEDB. Inside my database I have a user table with the following layout ID - Autonumber Username - Text Password - Text Email - Text To insert data into the table I use the following query INSERT INTO Users (Username, Password, Email) VALUES ('004606', 'Password', '[email protected]') However I seem to get an error with this statement and according to VB it's a syntax error. But then I tried to use the following query INSERT INTO Users (Username) Values ('004606') This query seemed to work absolutely fine... So the problem is I can insert into just one field but not all 3 (excluding the ID field because it's an autonumber). Any help would be appreciated, Thanks

• Managing Strategy objects with Hibernate & Spring

  - by Francois

  This is a design question better explained with a Stack Overflow analogy: Users can earn Badges. Users, Badges and Earned Badges are stored in the database. A Badge’s logic is run by a Badge Condition Strategy. I would prefer not to have to store Badge Condition Strategies in the database, because they are complex tree structure objects. How do I associate a Badge stored in the database with its Badge Condition Strategy? I can only think of workaround solutions. For example: create 1 class per badge and use a SINGLE_TABLE inheritance strategy. Or get the badge from the database, and then programmatically lookup and inject the correct Badge Condition Strategy. Thanks for suggesting a better design.

• Cakephp 1.3, router and authentication problem

  - by Zhlobopotam

  Trying to implements simple privileges for admin user. Don't need huge acl rules and groups system. There are admin users, overs - just registered users. They can't access actions with admin prefix. So It was implemented in cakephp1.2 version with following code in app_controller: function isAuthorized() { if (isset($this->params[Configure::read('Routing.admin')])) { if ($this->Auth->user('admin') != 1) { return false; } } return true; } But in 1.3 Routing.admin had been deprecated. How to rewrite it for use with 1.3 framework? Need some help.

• where should I put the EF entity and data annotations in asp.net mvc + entity framework project

  - by giddy

  So I have a DataEntity class generated by EntityFramework4 for my sqlexpress08 database. This data context is exposed via a WCF Data Service/Odata to silverlight and win forms clients. Should the data entities + edmx file (generated by EF4) go in a separate class library? The problem here then is I would specify data annotations for a few entities and then some of them would require specific MVC attributes (like CompareAttribute) so the class library would also reference mvc dlls. There also happen to be entity users which will be encapsulated or wrapped into an IIdentity in the website. So its pretty tied to the mvc website. Or Should it maybe go in a Base folder in the mvc project itself? Mostly the website is data driven around the database, like approve users, change global settings etc. The real business happens in the silverlight and win forms apps. Im using mvc3 rc2 with Razor. Thanks

• Changing RubyGems Install Path

  - by kmurph79

  I'm using RVM. I recently updated RubyGems and it seems to have changed my install path. Currently RubyGems looks in /Users/kmurph79/.rvm/gems/ruby-1.9.1-p376 for gems, yet installs them in /Users/kmurph79/.rvm/rubies/ruby-1.9.1-p376/lib/ruby/gems/1.9.1/gems. Currently I have them all symlinked, but I'd like to avoid doing that everytime I install a gem. I tried editing .gemrc to have RubyGems look in the latter directory, but that didn't work (maybe I didn't do that correctly? Here is my current .gemrc file). Ideally I'd like to change the install path to the former directory -- is there an easy way to do this? Thanks for any help!

• msvsmon is locking up my pdbs

  - by Sam Saffron

  During developement of my media center plugin (which has a few custom build steps to gac stuff and such) msvsmon has a rather annoying behaviour. First compilation usually goes well, but subsequent compilations complain about myplugin.pdb being locked Error 1 Unexpected error creating debug information file 'C:\Users\sam\source\myfile.PDB' -- 'C:\Users\sam\source\obj\Debug\myfile.pdb: The process cannot access the file because it is being used by another process. If I exit VS and nuke the object directory, I am able to compile again. Also, if I kill off msvsmon.exe I am able to compile again (but can not debug) Has anyone seen this error? Are there any workarounds? I already disabled live semantic errors, just in case.

• MVC Application Design

  - by Paul Brown

  Hello I am about to create my first proper application in ASP.NET MVC3. It is basically a jobs site with 3 levels: 1) Users - No registration and can view all jobs posted on the website 2) Posters - Need to register and login to post adverts 3) Admin - Need to register and login to post adverts and review postings before they go live Would you suggest I use the same Jobs controller for the three levels I mention above? With a LIST action to show jobs to "Users" and a CREATE & EDIT action for the "Posters" & "Admin"? Thanks Paul

• Netbeans 7.2 won't open on OS X

  - by Mark van Wyk

  I installed Netbeans on OSX Mountain Lion running JDK 7. Everything was working fine. Then my machine for no reason crashed. After this I could no longer open Netbeans anymore. If I try to start Netbeans from the commandline: /Applications/NetBeans/NetBeans 7.2.app/Contents/MacOS/netbeans Then it works fine. From there I can select Netbeans About and confirm that my userdir and cachedir is: User directory: /Users/<user>/Library/Application Support/NetBeans/7.2 Cache directory: /Users/<user>/Library/Caches/NetBeans/7.2 So, I deleted these directories and tried again, but alas, I can only start netbeans via the commandline. Ideas appreciated...

• ASP.NET plug-in architecture, settings problem

  - by Xaqron

  I want to divide business layer (BLL) of an asp.net application into multiple components. Each component is a .NET class library which is compiled as a standalone DLL. These components should have their own configuration files. For example "MyNameSpace.Users.dll" contains classes about users of the website and there's a password policy to check if password length is at least x characters. When webmaster edits the config file of this DLL and set x to y then component (DLL) should use new value (y) in the future and enforce passwords to be at least y characters. I want each component as a single project and compile them separaely (and not to put all projects in a solution in Visual Studio), and put the DLLs of these libraries into the "Bin" folder of my ASP.NET application. Is it possible ? Where should I put these config files ?

• jquery refresh php loop?

  - by Elliott

  Hi, I have a page in which users can make "posts" its similar to facebook, I am trying to figure out how I can get it to run the php loop say every 10mins, in order for the person to see new posts. Everytime a post is made it is added into the db and then the page is refreshed, I want to do it more "facebook like". Using jquery slide down etc. Below is what I have up2 now. function postdata() { $.ajax({ type: "POST", dataType: "text", url: "makepost.php", data: "post_text=" + $("#post_text").val(), cache: false, success: function(reply_text) { if (reply_text.indexOf("Successful") >= 0) { alert("Post Made"); window.location = "index.php" } else { alert(reply_text); } } }); } </script> <div id="content"> <?php if (loggedin()) { $ID = getID(); $query = "SELECT * FROM `posts`"; $result=mysql_query($query); $count=mysql_num_rows($result); $users = "SELECT `userID` FROM `users`"; $resultID=mysql_query($users); while ($row = mysql_fetch_array($result)) { echo '<div class="posts">'; echo $row['2']."<br /><br />"; echo '<div class="posts_bottom">'; echo '<p class="name">'; echo showuser($row['1'])."</p>"; echo '<p class="rate">'; echo '<input type="submit" value="+1"/></p>'; echo '<p class="points">'; echo showpoints($row['1'])."</p>"; echo "</div>"; echo '</div>'; } echo '<div id="makepost"> <br /><textarea rows="3" cols="25" id="post_text" ></textarea><br /> <input type="submit" id="post_bttn" value="Post" onclick="postdata(); return false;"> </div>'; As they are put into a new div everytime I don't know what to refresh? Such as if it was one div I could jus refresh that, but these are being created and I don't know how many would need to be loaded. Any adivce? Thanks alot :D

• iOS app won't compile on device but works fine in simulator

  - by Jhorra

  I'm assuming this has something to do with linking, but I've removed RestKit and re-added it. I made sure all my connections and linking was in place. If I set XCode to use the simulator it runs fine, but as soon as I set it to run on any device it won't even build. The only other thing of note is this didn't start happening till I upgraded to XCode 4.5. Below are the errors it gives me ld: warning: ignoring file /Users/luke/Library/Developer/Xcode/DerivedData/ehrx-btsujlxuhtytahfaikwjeqfjybtt/Build/Products/Debug-iphoneos/libRestKit.a, file was built for archive which is not the architecture being linked (armv7s): /Users/luke/Library/Developer/Xcode/DerivedData/ehrx-btsujlxuhtytahfaikwjeqfjybtt/Build/Products/Debug-iphoneos/libRestKit.a Undefined symbols for architecture armv7s: "_OBJC_CLASS_$_RKClient", referenced from: objc-class-ref in ehrxAppDelegate.o objc-class-ref in ehrxLoginView.o objc-class-ref in ehrxInboxView.o objc-class-ref in ehrxCMView.o objc-class-ref in ehrxEncounterDemoView.o objc-class-ref in ehrxEncounterDiagListView.o objc-class-ref in ehrxEncounterChargeView.o ... ld: symbol(s) not found for architecture armv7s clang: error: linker command failed with exit code 1 (use -v to see invocation)

• URLs with query stripped of ampersands appearing in error logs

  - by Jeremy DeGroot

  I've noticed a curious phenomena popping up in my error logs recently. If, as the result of processing a form, I redirect my users to the URL http://www.example.com/index.php?foo=bar&bar=baz, I will see the following two URLs in my log http://www.example.com/index.php?foo=barbar=baz http://www.example.com/index.php?foo=bar&bar=baz The first one is obviously incorrect and will cause my application to redirect to a 404. It always appears first, usually a second before the second one. The 404 page is not doing the redirection, so it appears that the browser is trying both versions. At first, looking at my server logs made me believe it affected only Firefox 3.6.3, but I've found an example of Safari being afflicted as well. It happens fairly intermittently, though it can occur multiple times in a users' session. I've never been able to get it to happen to me. Any thoughts as to the nature of the problem or a solution?

• Is it possible to reliably auto-decode user files to Unicode? [C#]

  - by NVRAM

  I have a web application that allows users to upload their content for processing. The processing engine expects UTF8 (and I'm composing XML from multiple users' files), so I need to ensure that I can properly decode the uploaded files. Since I'd be surprised if any of my users knew their files even were encoded, I have very little hope they'd be able to correctly specify the encoding (decoder) to use. And so, my application is left with task of detecting before decoding. This seems like such a universal problem, I'm surprised not to find either a framework capability or general recipe for the solution. Can it be I'm not searching with meaningful search terms? I've implemented BOM-aware detection (http://en.wikipedia.org/wiki/Byte_order_mark) but I'm not sure how often files will be uploaded w/o a BOM to indicate encoding, and this isn't useful for most non-UTF files. My questions boil down to: Is BOM-aware detection sufficient for the vast majority of files? In the case where BOM-detection fails, is it possible to try different decoders and determine if they are "valid"? (My attempts indicate the answer is "no.") Under what circumstances will a "valid" file fail with the C# encoder/decoder framework? Is there a repository anywhere that has a multitude of files with various encodings to use for testing? While I'm specifically asking about C#/.NET, I'd like to know the answer for Java, Python and other languages for the next time I have to do this. So far I've found: A "valid" UTF-16 file with Ctrl-S characters has caused encoding to UTF-8 to throw an exception (Illegal character?) (That was an XML encoding exception.) Decoding a valid UTF-16 file with UTF-8 succeeds but gives text with null characters. Huh? Currently, I only expect UTF-8, UTF-16 and probably ISO-8859-1 files, but I want the solution to be extensible if possible. My existing set of input files isn't nearly broad enough to uncover all the problems that will occur with live files. Although the files I'm trying to decode are "text" I think they are often created w/methods that leave garbage characters in the files. Hence "valid" files may not be "pure". Oh joy. Thanks.

• How to filter results by multiple fields?

  - by hadees

  I am working on a survey application in ruby on rails and on the results page I want to let users filter the answers by a bunch of demographic questions I asked at the start of the survey. For example I asked users what their gender and career was. So I was thinking of having dropdowns for gender and career. Both dropdowns would default to all but if a user selected female and marketer then my results page would so only answers from female marketers. I think the right way of doing this is to use named_scopes where I have a named_scope for every one of my demographic questions, in this example gender and career, which would take in a sanitized value from the dropdown to use at the conditional but i'm unsure on how to dynamically create the named_scope chain since I have like 5 demographic questions and presumably some of them are going to be set to all.

• AppData\Roaming folder in windows service project

  - by vikash

  I need a help on getting Special folder in windows service program. I used this code in my Windows Form application: Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData); and got the path, ""C:\Users\\AppData\Roaming"* But if I run the same code in my Winows Service project I got the path: "C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\" But I need the earlier path (got in Windows Form). How do I get the same path in Service projet also. I have user setting file, log, config file in the "C:\Users\\AppData\Roaming" folder. So I have to refer the same path both in my Windows Form application and Windows Service project. Can somebody tell me, what is the difference here and how do i get the same path in both type of project? Thanks, sharath

• how to: handle exceptions, best practices

  - by b0x0rz

  need to implement a global error handling, so maybe you can help out with the following example... i have this code: public bool IsUserAuthorizedToSignIn(string userEMailAddress, string userPassword) { // get MD5 hash for use in the LINQ query string passwordSaltedHash = this.PasswordSaltedHash(userEMailAddress, userPassword); // check for email / password / validity using (UserManagementDataContext context = new UserManagementDataContext()) { var users = from u in context.Users where u.UserEMailAdresses.Any(e => e.EMailAddress == userEMailAddress) && u.UserPasswords.Any(p => p.PasswordSaltedHash == passwordSaltedHash) && u.IsActive == true select u; // true if user found return (users.Count() == 1) ? true : false; } } and the md5 as well: private string PasswordSaltedHash(string userEMailAddress, string userPassword) { MD5 hasher = MD5.Create(); byte[] data = hasher.ComputeHash(Encoding.Default.GetBytes(userPassword + userEMailAddress)); StringBuilder stringBuilder = new StringBuilder(); for (int i = 0; i < data.Length; i++) { stringBuilder.Append(data[i].ToString("x2")); } Trace.WriteLine(String.Empty); Trace.WriteLine("hash: " + stringBuilder.ToString()); return stringBuilder.ToString(); } so, how would i go about handling exceptions from these functions? they first one is called from the Default.aspx page. the second one is only called from other functions from the class library. what is the best practice? surround code INSIDE each function with try-catch surround the FUNCTION CALL with try-catch something else?? what to do if exceptions happen? in this example: this is a user sign in, so somehow even if everything fails, the user should get some meaningful info - along the lines: sign in ok (just redirect), sign in not ok (wrong user name / password), sign in not possible due to internal problems, sorry (exception happened). for the first function i am worried if there is a problem with database access. not sure if there is anything that needs to be handled in the second one. thnx for the info. how would you do it? need specific info on this (easier for me to understand), but also general info on how to handle other tasks/functions. i looked around the internet but everyone has different things to say, so unsure what to do... will go with either most votes here, or most logicaly explained answer :) thank you.

• Sockets receiving null (Android)

  - by Henrik

  I have a android app that is communicating with a server (written in java). Between these two parts I have established a Socket connection and want to send data. The problem I am having is that sometimes, for some users, the information that reaches the server is null. This works (for all phones, all users): Server: int a = Integer.parseInt(in.readLine()); int b = Integer.parseInt(in.readLine()); int c = Integer.parseInt(in.readLine()); int d = Integer.parseInt(in.readLine()); String checksum = in.readLine(); String model = in.readLine(); String device = in.readLine(); String name = in.readLine(); Client: out.println(a); out.println(b); out.println(c); out.println(d); out.println(hash); out.println(Build.MODEL); out.println(Build.DEVICE); String name = fixName(); out.print(name); out.flush(); This does not work (for some users): Server: int a = Integer.parseInt(in.readLine()); String checksum = in.readLine(); String model = in.readLine(); String device = in.readLine(); String name = in.readLine(); String msg = in.readLine(); int version = -1; String test = "hej"; try{ test = in.readLine(); version = Integer.parseInt(test); }catch(Exception e){ e.printStackTrace(); } Client: out.println(a); out.println(hash); out.println(Build.MODEL); out.println(Build.DEVICE); String name = fixName(); if(name == null) name = "John Doe"; out.println(name); String msg = fixMsg(); if(msg == null) name = "nada"; out.println(msg); out.println(curversion); out.flush(); Sometimes, in the second case, the name, msg, and version (the string test) are null at the server side. The catch is triggered because test is null. curversion,a are ints, the rest are strings. Any ideas?

• Can I add an additional eula/tos inside my app on top of the iphone app store agreement

  - by nickthedude

  I have an app that allows users to generate and publish content. I would like to possibly be able to use the content they publish/create to make derivative works, ie books etc (similar to what icanhazcheeseburger has done.) If I were to put an opt in alert to ask the user whether or not they would like to be a part of this, would this violate the iphone sdk? I know this is not programming question so I'm not sure if this is a fair question, but I thought I heard something like you can't add a eula you have to abide by whatever apple dictates in their app store agreement. Also if you have suggestions on different ways to approach getting users to agree to this I'm all ears, but yes that is kind of subjective. Thanks folks, Nick

• WordPress MU: Login from main page but not individual blogs

  - by bradrhine

  I recently upgraded to WPMU 2.8.6 and ever since, my users can't log in on their individual blogs, but they can log in from the main page. My site is at blogs.mtwp.net (we're a school district). So if a user goes to blogs.mtwp.net/BLOGNAME/wp-login.php, their password is rejected. If they go toblogs.mtwp.net/wp-login.php, they can log in and get to the dashboard from there. But it's not all users. Site admins can get in just fine. We're using wpDirAuth 1.4 if that makes a difference. Honestly, I'm stumped. Any help would be very much appreciated. Thanks!

• Rails Model multiple column uniqueness

  - by Jty.tan

  I am making a Viewer model with belongs_to :users belongs_to :orders that joins the models Users and Orders with a :has_many :through => :viewers. And the Viewer model has the attributes of user_id and order_id. How would I set it up so that new viewers are only accepted if both user_id and order_id are unique in the same row? I remember in MySQL being able to do so with a flag (although I can't for the life of me remember what it was), but I'm not sure how to do it with Rails. Can I do something like (for Viewer.rb) validates_uniqueness_of :user_id, :scope => :order_id?
