  • Rails: How to produce 404 or redirect upon undesired url exploitation?

    - by Baby Diego
    I want to hide the urls for editing users and their profiles behind safer and meaningful urls. For instance, I want /user/13/edit to be /settings/account and /user/13/profile/edit to be /settings/profile. I managed to achieve that, but for that I had to load the user information from the current_user bit from the session. Like so: # users_controller def edit @user = current_user end # profiles_controller def edit @user = current_user @profile = @user.profile end But now, since I can't compare @user.id from the params with the current_user in the session, how can I stop the old urls (/user/13/edit and /user/13/profile/edit) from being exploitable? They always load the forms for the current user, so there's no harm done, but I'd be more comfortable if they just produced a 404 error or something. Thanks in advance.

  • Domain Model and Contracts

    - by devoured elysium
    I am modelling a DVD Rental Store: A Client gives its clientNumber to the System. The System checks whenever the given clientNumber is valid. The Client gives the name of the DVD he wants to rent. ... n. ...I will later have to form an association between a new instance of "RentDVD" class concept to the current Client c. My Domain Model is something like: I've made the Contract for the first and second operations as: Preconditions: none Postconditions: there exists a Client c such that c.clientNumber = clientNumber. Now, I don't know if I should form an association between this Client c and the DVDStore(that I intend to use as front-end). If I don't make the association, how will I later be able to "reference" this same Client? Should I be making an association between Client and a different concept? Thanks

  • Best Practice of Field Collapsing in SOLR 1.4

    - by Dominik
    I need a way to collapse duplicate (defined in terms of a string field with an id) results in solr. I know that such a feature is comming in the next version (1.5), but I can't wait for that. What would be the best way to remove duplicates using the current stable version 1.4? Given that finding duplicates in my case is really easy (comparison of a string field), should it be a Filter, should I overwrite the existing SearchComponent or write a new Component, or use some external libraries like carrot2? The overall result count should reflect the shortened result.

  • Publish web application from MSBuild Script using VS2010 targets resets working directory

    - by Raoul
    I am trying to automatically publish and deploy my .Net 4 web application automatically from a build script to be run by our continuous integration server. I am using the new _WPPCopyWebApplication target from VS2010 to perform the publish, however it appears to reset the current working directory of the msbuild project to c:\ this causes my prebuild steps to fail as they have relative paths to some external tools. The task I am running from our master.build file is as follows: <Target Name="PublishWeb"> <MSBuild Projects="$(ProjectPath)" Targets="ResolveReferences;_WPPCopyWebApplication" Properties="WebProjectOutputDir=$(DeployPath);OutDir=$(TempOutputFolder)$(WebOutputFolder)\;OutputPath=$(ProjectPath)\bin\Debug;" /> </Target> This does not happen when using the legacy _CopyWebApplication. Does anyone have any idea how to resolve this problem?

  • Create pdf file dynamically in vb.net for .net 1.1 framework

    - by Urbycoz
    I need to create a pdf file dynamically in vb.net. It needs to contain several images and lines of text. I am using VS 2003, so whatever solution I use will need to be compatible with the .net 1.1 framework. The current method I am using is wpcubed, but this requires that all images be converted to bmp format before adding them to the pdf, which can be extremely slow when dealing with a large number of images. I am aware that there are an awful lot of other 3rd party products that claim to do this, and I have had a search through them. But without registering, downloading, installing and writing code to use each of them in turn, it is very difficult to differentiate between them. So far I have looked into evo pdf and pdfsharp but neither seem to work with .net 1.1. (Although they don't make this abundantly clear.) Has anyone else found a method that works and they would recommend (a free one-if possible)?

  • long processes php

    - by significance
    hi, i need to run a really long php script (four and half, five hours). the script sometimes runs successfully, but sometimes gets killed inexplicably (poss something to do with the shared hosting??). i think that the solution maybe to run the script is smaller chunks. in order to do this i have written a script that stores it's status & position in an xml file, and executes one chunk of the script, before moving the position on. i am having problems hooking up the last bit of the script, which should end the current process & re-execute the script. or maybe i am barking up the wrong tree completely! i have read through what i can find on SO and elsewhere but i'm still none the wiser :( please help!!! dan

  • Opening Large (24 GB) File In C

    - by zacaj
    I'm trying to read in a 24 GB XML file in C, but it won't work. I'm printing out the current position using ftell() as I read it in, but once it gets to a big enough number, it goes back to a small number and starts over, never even getting 20% through the file. I assume this is a problem with the range of the variable that's used to store the position (long), which can go up to about 4,000,000,000 according to http://msdn.microsoft.com/en-us/library/s3f49ktz%28VS.80%29.aspx, while my file is 25,000,000,000 bytes in size. A long long should work, but how would I change what my compiler(Cygwin/mingw32) uses or get it to have fopen64?

  • Check if there are any repeated elements in an array recursively

    - by devoured elysium
    I have to find recursively if there is any repeated element in an integer array v. The method must have the following signature: boolean hasRepeatedElements(int[] v) I can't see any way of doing that recursively without having to define another method or at least another overload to this method (one that takes for example the element to go after or something). At first I thought about checking for the current v if there is some element equal to the first element, then creating a new array with L-1 elements etc but that seems rather inefficient. Is it the only way? Am I missing here something?

  • Nested sql queries in rails when :has_and_belongst_to_many

    - by Godisemo
    Hello, In my application I the next task that has not already been done by a user. I have Three models, A Book that has many Tasks and then I have a User that has has and belongs to many tasks. The table tasks_users table contains all completed tasks so I need to write a complex query to find the next task to perform. I have came up with two solutions in pure SQL that works, but I cant translate them to rails, thats what I need help with SELECT * FROM `tasks` WHERE `tasks`.`book_id` = @book_id AND `tasks`.`id` NOT IN ( SELECT `tasks_users`.`task_id` FROM `tasks_users` WHERE `tasks_users`.`user_id` = @user_id) ORDER BY `task`.`date` ASC LIMIT 1; and equally without nested select SELECT * FROM tasks LEFT JOIN tasks_users ON tasks_users.tasks_id = task.id AND tasks_users.user_id = @user_id WHERE tasks_users.task_id IS NULL AND tasks.book_id = @book_id LIMIT 1; This is what I Have done in rails with the MetaWhere plugin book.tasks.joins(:users.outer).where(:users => {:id => nil}) but I cant figure out how to get the current user there too, Thanks for any help!

  • VBScript - copy files modified in last 24 hours

    - by Martin North
    Hi, I'm trying to copy files from a directory where the last modified date is within 24hours of the current date. I'm using a wildcard in the filepath as it changes every day I'm using; option explicit dim fileSystem, folder, file dim path path = "d:\x\logs" Set fileSystem = CreateObject("Scripting.FileSystemObject") Set folder = fileSystem.GetFolder(path) for each file in folder.Files If DateDiff("d", file.DateLastModified, Now) < 1 Then filesystem.CopyFile "d:\x\logs\apache_access_log-*", "d:\completed logs\" WScript.Echo file.Name & " last modified at " & file.DateLastModified end if next Unfortunately this seems to be copying all files, and not just the recently modified ones. Can anyone point me in the right direction? many thanks Martin.

  • Struts 2 Select tag

    - by nathj07
    I'm pretty new to the jsp and struts way of doing things and so far I like what I see. My current question is with the use of the struts select tag. I have a page that displays a number of dropdown boxes using struts select currently the options are hard coded in the jsp. I would like to populate them based on a properties file. However I have no idea where to start. I assume I need to take the contents of a properties file into an Array (of some sort) and assign that to the select tag. My questions are: Where does the code t build the array go? How do I connect that array to the select tag?

  • How Do I Add Value To All Previous Values In Array

    - by James
    Lets say I have the following array: my_array = [1, 5, 8, 11, -6] I need to iterate over this array and add the values prior to the current value together. An example will probably be easier to understand. I need to return an array that should look something like this: final_array = [1, 6, 14, 25, 19] I have tried doing something like this: my_array.collect {|value| value + previous_values } But obviously that doesn't work because I can't figure out how to get the previous values in the array. I am a programming noob so this might be easier than I am making it. I am pretty sure I need to use either collect or inject, but I can't seem to figure out how to do this. Any help would be appreciated.

  • Showing value of UISlider inside App Prefs?

    - by Garrett H
    I have a settings bundle, working perfectly, that I would like to customize a bit. I have, among other things, a PSSliderSpecifier and a PSTitleValueSpecifier. What I would like to do is change the value of the PSTitleValueSpecifier to show the current value of the slider, preferably updating every time the slider's value changes (Actually, what I'd like even more would be displaying the slider's value on the same row as the slider). I know the settings bundle is rather strict about what you're allowed to do in it, but is there any way of doing this?

  • Making a window pop in and out of the edge of the screen

    - by Brad
    I'm trying to re-write an application I have for Windows in Objective-C for my Mac, and I want to be able to do something like Mac's hot corners. If I move my mouse to the left side of the screen it will make a window visible, if I move it outside of the window location the window will hide again. (window would be pushed up to the left side of screen). Does anyone know where I can find some demo code (or reference) on how to do this, or at least how to tell where the mouse is at, even if the current application is not on top. (not sure how to word this, too used to Windows world). Thank you -Brad

  • Using Range Function

    - by Michael Alexander Riechmann
    My goal is to make a program that takes an input (Battery_Capacity) and ultimately spits out a list of the (New_Battery_Capacity) and the Number of (Cycle) it takes for it ultimately to reach maximum capacity of 80. Cycle = range (160) Charger_Rate = 0.5 * Cycle Battery_Capacity = float(raw_input("Enter Current Capacity:")) New_Battery_Capacity = Battery_Capacity + Charger_Rate if Battery_Capacity < 0: print 'Battery Reading Malfunction (Negative Reading)' elif Battery_Capacity > 80: print 'Battery Reading Malfunction (Overcharged)' elif float(Battery_Capacity) % 0.5 !=0: print 'Battery Malfunction (Charges Only 0.5 Interval)' while Battery_Capacity >= 0 and Battery_Capacity < 80: print New_Battery_Capacity I was wondering why my Cycle = range(160) isn't working in my program?

  • Why can't QFile read from the "~" directory?

    - by hurikhan77
    I've tried the following short example to find out about a bug in a bigger program I am working on. It looks like QFile doesn't support unix (or the shell's) notation for the home directory: #include <QFile> #include <QDebug> int main() { QFile f("~/.vimrc"); if (f.open(QIODevice::ReadOnly)) { qDebug() << f.readAll(); f.close(); } else { qDebug() << f.error(); } } As soon as I replace the "~" with my real home directory path, it works. Is there an easy workaround - some setting to enable? Or do I have to go the "ugly" way and ask QDir for the home directory of the current user and prepend that manually to each path?

  • facebook messages result set like part 2

    - by David
    Hey guys, I don't think I'm getting it right. Here is my most recent query that I believe is almost working. SELECT max(sender_id) as sender_id, subject, MAX(id) as message_id, MAX(created_at) as updated_at FROM messages where (recipient_id = #{current_user} and recipient_deleted = 'f') or sender_id = #{current_user} GROUP BY subject ORDER BY max(created_at) DESC ; Basically the goal is to fetch all recent messages of a user, group them by subject, and make sure that the photo that is showing up is the other party's photo, never the current user. (also need the most recent message body and message count but that is for another time) Here is what I think is wrong. doing max(sender_id) is wrong, since the current_user id could be higher than the sender's id. I am using the sender_id in the html page to fetch the user's photo.

  • Date in textboxes changing format

    - by AWinters
    I have an application (asp.net 3.5) that support 4 different languages. Along with other cultural changes, the date formats must match the current culture on out reporting pages. We set the date formats of each of the textboxes like: string date = DateTime.Today.ToString("d"); //returns the date portion only textbox1.Text = date; textbox2.Text = date; etc... When the user selects Spanish or British English the format should be dd/mm/yyyy. However, then I navigate to the page it displays in mm/dd/yyyy. After a postback it then displays dd/mm/yyyy. After another postback it switches to the mm/dd/yyyy format and on and on. I have debugged through this and I see that the culture is correct for the application and the date formats are returned to me correctly, yet when it displays, it displays incorrectly. Has anyone ever seen this or know what is happening?

  • Implementing tracing gestures on iPhone

    - by bmoeskau
    I'd like to create an iPhone app that supports tracing of arbitrary shapes using your finger (with accuracy detection). I have seen references to an Apple sample app called "GestureMatch" that supposedly implemented exactly that, but it was removed from the SDK at some point and I cannot find the source anywhere via Google. Does anyone know of a current official sample that demonstrates tracing like this? Or any solid suggestions on other resources to look at? I've done some iPhone programming, but not really anything with the graphics API's or custom handling of touch gestures, so I'm not sure where to start.
