• Creating a skin engine in MVC

  - by Joe

  Does anyone have any experience creating a skin engine for asp.net MVC? I know the suggested approach is to use flexible markup with CSS, but I would like the ability for a new view to be dropped in, and the application use that one instead of the default one. Basically, I want to know how to tell the framework (at run time) to look into a specific folder for the views/content, and if the item isn't there to check the default locations. I started to look into how the Oxite blog engine does it, but it seems like that might be a bit much for what I need (I am still looking through it, so I could be wrong.) Any help is appreciated.

• Identifying individual values in a text box using Flash

  - by Jamash1989

  I want to identify specific strings in a text box from user input to add to a score variable, like so - if (userWords.text == firstWord) { score = score + 1; } The example given adds 1 to the score, but if a user adds a space then a second word the text box views it as a whole and not individual words, resulting in no values added to the score variable. The problem lies with the whole text box being viewed as one entire string. Instead, I want to split it up so word1 will add 1 to the score, word2 will add 1 to the score, etc. I am ultra confused with this problem, so thank you to anyone that may help.

• Can you create a HIPAA compliant Amazon S3 Web Application?

  - by xkingpin

  I am facing some questions when trying to design an S3 application using ASP.NET MVC and trying to stay HIPAA compliant. My initial plan was to require an SSL connection to my web server, encrypt the images on my server, then send them to s3 using my private keys. Here's my obvious concerns: You cannot store unencrypted images in any temporary file cache when client views images within the browser. Even if I setup an ashx to generically handle the image in memory, couldn't this get stored in cache? Saying the images will be encrpyted because you will be connecting to my server via https still does not guarantee all browsers will not cache data. It's not possible to even consider the "Query String" with expiration option since data will be encrypted before being stored on disk at s3, and will again be decrypted at my server in memory. I think my only option would be to write/purchase some sort of ActiveX component that will not expose the image as a simple html image source or write my app as a client side WinForm application.

• How to get a list of names + a count of occurrences relating to the name from another table

  - by Jacob Degeling

  Hi, Hope my subject line was descriptive enough. Basically, I have a table called Students, and one called Absences. The Students table contains student information (Name, DOB, StudentID etc.), the Absences table contains any absences (Date, Reason, related by StudentID). I want to get a full list of the students, plus a count of their absences. Sample results would be: StudentName Absences ------------- ----------- Johnny 3 Mark 2 James 1 Anthony 0 Sharon 0 Can someone suggest a way I should tackle this problem? I would prefer to have a single SQL statement, possibly incorporating some views etc. Thanks, Jacob.

• Data Structure for a particular problem??

  - by AGeek

  Hi, Which data structure can perform insertion, deletion and searching operation in O(1) time in the worst case. We may assume the set of elements are integers drawn from a finite set 1,2,...,n, and initialization can take O(n) time. I can only think of implementing a hash table. Implementing it with Trees will not give O(1) time complexity for any of the operation. Or is it possible?? Kindly share your views on this, or any other data structure apart from these.. Thanks..

  In the iPod app, the navigation views have the default status bar style, and the Now Playing view is in the black style. The transition between them is animated with a crossfade. I want to do that. My first attempt: [UIView beginAnimations:@"whatever" context:nil]; [UIView setAnimationDuration:0.5]; self.navigationController.navigationBar.barStyle = UIBarStyleBlack; [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlack [UIView commitAnimations]; No joy, it pops to black. Takers?

• require_owner code to limit controller actions not recognizing current user as owner

  - by bgadoci

  I am trying to restrict access to certain actions using a before_filter which seems easy enough. Somehow the ApplicationController is not recognizing that the current_user is the owner of the user edit action. When I take the filter off the controller correctly routes the current_user to their edit view information. Here is the code. Link to call edit action from user controller (views/questions/index.html.erb): <%= link_to "Edit Profile", edit_user_path(:current) %> ApplicationController (I am only posting the code that I think is affecting this but can post the whole thing if needed). class ApplicationController < ActionController::Base def require_owner obj = instance_variable_get("@#{controller_name.singularize.camelize.underscore}") # LineItem becomes @line_item return true if current_user_is_owner?(obj) render_error_message("You must be the #{controller_name.singularize.camelize} owner to access this page", root_url) return false end end and the before_filter class UsersController < ApplicationController before_filter :require_owner, :only => [:edit, :update, :destroy] #... end I simply get the rendering of the error message from the ApplicationController#require_owner action.

• Index an array expression directly in PostgreSQL

  - by wich

  I'm trying to insert data into a table from a template table. I need to rewrite one of the columns for which I wanted to use a directly indexed array expression, but I can't seem to find how to do this, if it is even possible. The scenario: create table template ( id integer, index integer, foo integer); insert into template values (0, 1, 23), (0, 2, 18), (0, 3, 16), (0, 4, 7), (1, 1, 17), (1, 2, 26), (1, 3, 11), (1, 4, 3); create table data ( data_id integer, foo integer); Now what I'd like to do is the following: insert into data select (array[3,7,5,2])[index], foo from template where id = 1; But this doesn't work, the (array[3,7,5,2])[index] syntax isn't valid. I tried a few variants, but was unable to get anything working and wasn't able to find the correct syntax in the docs, nor even whether this is at all possible or not. As a current workaround I've devised the following, but it is less than ideal, from an elegance perspective at least, but it may also be a performance hit, I haven't looked into that yet. insert into data select arr[index], foo from template, (select array[3,7,5,2] as arr) as q where id = 1; If anyone could suggest a (better) alternative to accomplish this I'd like to hear that as well.

• Problem with Models on Master Page View.

  - by user342514

  Have a problem with master page views and models. In the first image, I have a simple view in which I am trying to access the Model properties. None of the model properties are available at this time (this is the problem). If I use a <%= Model.blah % then you can see that the model properties are available. Second photo. In the last photo you will now see that I can access the Model properties that I was trying to access in the first photo. An error will be thrown if viewing this page if you don't first do <%= with the model. CS1061: 'object' does not contain a definition for 'User' and no extension method 'User' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) http://yfrog.com/8b43656447p So why is this happening?

• Tab widget example not running

  - by michbeck

  I'm trying to reproduce the tabwidget example (http://developer.android.com/resources/tutorials/views/hello-tabwidget.html). I'm not really sure what's the problem, I got no errors while compiling, but i cannot see the application on the emulators screen.

• Kohana controller shows blank page if missing URI segment/argument

  - by Petruza

  When accessing http://www.nowplayingnashville.com/event2/detail/440698386/Whatever the controller shows normally. But when omitting the last parameter (event's title, which can be any string), http://www.nowplayingnashville.com/event2/detail/440698386/ It shows blank. I added a default value and tried to hardcode the title on the first line of the controller, but it doesn't work anyway. It looks like a view issue, because I can add an echo at the end of the controller and it gets printed, so the controller is executing to the end, but the views aren't displayed. This problem is present on the live site, but I checked out the code on my local machine and it works perfectly without a title. That's strange. Could it be a Kohana or Apache configuration issue?

• Calculate the contentsize of scrollview

  - by neha

  Hi all, I'm having a scrollview as the detailedview of tableview cell. There are multiple views on the detailedview like labels, buttons etc. which I'm creating through interface builder. What I'm creating through interface builder is static. I'm putting everything on a view of height 480. A label on my detailedview is having dynamic text which can extend to any length. The problem is that I need to set the scrollview's content size for which I need its height. How shall I set scrollview's height provided the content is dynamic?

• Django "Page not found" error page shows only one of two expected urls

  - by Frank V

  I'm working with Django, admittedly for the first time doing anything real. The URL config looks like the following: urlpatterns = patterns('my_site.core_prototype.views', (r'^newpost/$', 'newPost'), (r'^$', 'NewPostAndDisplayList'), # capture nothing... #more here... - perhaps the perma-links? ) This is in an app's url.py which is loaded from the project's url.py via: urlpatterns = patterns('', # only app for now. (r'^$', include('my_site.core_prototype.urls')), ) The problem is, when I receive a 404 attempting to utilize newpost, the error page only shows the ^$ -- it seems to ignore the newpost pattern... I'm sure the solution is probably stupid-simple but right now I'm missing it. Can someone help get me on the right track...

• How to build the ViewModel in MVVM not to violate the Single Responsibility Principle?

  - by Przemek

  Robert Martin says: "There should never be more than one reason for a class to change". Let's consider the ViewModel class which is bound to a View. It is possible (or even probable) that the ViewModel consists of properties that are not really related to each other. For small views the ViewModel may be quite coherent, but while the application gets more complex the ViewModel will expose data that will be subject to change for different and unrelated reasons. Should we worry about the SRP principle in the case of ViewModel class or not?

• search engine (solr/sphinx) question

  - by noname

  i want to make my threads content searchable with full text search engines like solr. but i wonder one thing. should i index just the thread.title, thread.body and post.body or should i index username, created date, nr of posts, views, country, region and city too that belongs to thread? i mean when an user search for a thread he will get hits returned containing thread title, 2 lines of body, which user has posted it, creation date, tags, and so on. should i index all this information too? but then it would be pretty much the whole database. or should i just index the 3 first columns i mentioned for full text search. and another question. when an user post a new thread, then i have to immidiately tell solr to add that row? if im not, how would it be searchable?

• Security / Protecting code in JavaScript

  - by Evans

  With all the recent hype about JavaScript and HTML5 replacing Flash, I wanted to know - How would it be possible to protect client-side js code? Of course, it is possible to obfuscate it, but that would only make it a little harder. Also, for games which submit high scores to the server, wouldn't it be incredibly easy to modify those scores before they are sent to the server? I know even Flash files can be decompiled, but they can be obfuscated and flash decompilation is not as easy as modifying data in JS - could be done easily using a plugin such as Firebug. I'd like to know everyone's views on this.

• Tracking pageviews and displaying related data

  - by zeky

  I want track which articles a user read on a website. Then with that data, be able to know: 1) - top N articles read in the last hour/day/week/month 2) - show recommendations ("users who read this, also read that") 3) - same as (1), but for a specific section on the site Since the site has high traffic ( 1M views/day) i can't use a RDBMS for this. I started to look at NoSQL (cassandra specifically) and since it's all new to me i'm not sure it's what i need or not. I'm possitive i'm not the first one who needs something like this but couldn't find links/articles giving me pointers on how to do something like this. Is NoSQL the best aproach? Any tips on the data model? Thanks.

  - by Greg Lemond

  I have three models: Service has_many :prices has_many :groups, through: prices Price belongs_to :service belongs_to :group Group has_many :prices I want to have an input field (Simple_Form) for every price. In views/services/_form.html.haml I do: simple_form_for @service do |f| simple_fields_for :groups do |g| simple_fields_for :prices do |p| p.input :price With this setup I only get input fields for already saved prices. How I can get a price field for every group? I tried to do it manually, but it got really nasty and didn't work either. Thanks for any ideas!

• speed up the speed of a sql query to mysql?

  - by fayer

  in my mysql database i've got the geonames database, containing all countries, states and cities. i am using this to create a cascading menu so the user could select where he is from: country - state - county - city. but the main problem is that the query will search through all the 7 millions rows in that table each time i want to get the list of children rows, and that is taking a while 10-15 seconds. i wonder how i could speed this up: caching? table views? reorganizing table structure somehow? and most important, how do i do these things? are there good tutorials you could link to me? i appreciate all help and feedback discussing smart ways of handling this issue!

• pyramid - How to handle complex URL in a elegant way?

  - by Lingfeng Xiong

  I'm writing a admin website which control several websites with same program and database schema but different content. The URL I designed like this: http://example.com/site A list of all sites which under control http://example.com/site/{id} A brief overview of select site with ID id http://example.com/site/{id}/user User list of target site http://example.com/site/{id}/item A list of items sold on target site http://example.com/site/{id}/item/{iid} Item detailed information # ...... something similar As you can see, nearly all URL are need the site_id. And in almost all views, I have to do some common jobs like query Site model against database with the site_id. Also, I have to pass site_id whenever I invoke request.route_path. So... is there anyway for me to make my life easier? Thanks in advance.
