  • Rails Devise: How to access sign up page after signed in?

    - by Junior rails programmer
    hi All, I am new with rails and i am using "devise" gem for authentication purposes. At first i add a new user through default sign up page (E.g./users/sign_up) Then, i made "sign_up" page only available to signed_in users by following instructions from Devise before filter that prevents access to "new_user_registration_path" unless user is signed-in Now, after sign in process when i try open sign up page it always directs me to root_path! How can i access sign up page? My "roots.rb" file as follows: Example::Application.routes.draw do devise_for :users, :controllers => { :registrations => 'registrations'} resources :companies resources :orders resources :customers root :to => "welcome#index" end Thank you all!

  • Suggestions on how to track tag count for a particular object

    - by Robin Fisher
    Hi, I'm looking for suggestions on how to track the number of tags associated with a particular object in Rails. I'm using acts_as_taggable_on and it's working fine. What I would like to be able to do is search for all objects that have no tags, preferably through a scope i.e. Object.untagged.all My first thought was to use an after_save callback to update an attribute called "taggings_count" in my model: def update_taggings_count self.taggings_count = self.tag_list.size self.save end Unfortunately, this does the obvious thing of putting me in an infinite loop. I need to use an after_save callback because the tag_list is not updated until the main object is saved. Would appreciate any suggestions as I'm on the verge of rolling my own tagging system. Regards Robin

  • ASP.net repeater, scroll 3 at a time

    - by Christo Fur
    I have a list of data that I need to display in a web page 3 at a time The first needs to be displayed in a div called "left" , the second in a div called "centre" and the third in a div called "right". And I need to be able to scroll through the data with a pager. And so the next 3 results will be displayed in a similar way, and so on till the end of the data set Obviously the alternating templates in the repeater are not suitable for this. Is there a smarter way to achieve this?

  • How to resize an openGL window created with wglCreateContext?

    - by Nick
    Is it possible to resize an openGL window (or device context) created with wglCreateContext without disabling it? If so how? Right now I have a function which resizes the DC but the only way I could get it to work was to call DisableOpenGL and then re-enable. This causes any textures and other state changes to be lost. I would like to do this without the disable so that I do not have to go through the tedious task of recreating the openGL DC state. HWND hWnd; HDC hDC; void View_setSizeWin32(int width, int height) { // resize the window LPRECT rec = malloc(sizeof(RECT)); GetWindowRect(hWnd, rec); SetWindowPos( hWnd, HWND_TOP, rec->left, rec->top, rec->left+width, rec->left+height, SWP_NOMOVE ); free(rec); // sad panda DisableOpenGL( hWnd, hDC, hRC ); EnableOpenGL( hWnd, &hDC, &hRC ); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-(width/2), width/2, -(height/2), height/2, -1.0, 1.0); // have fun recreating the openGL state.... } void EnableOpenGL(HWND hWnd, HDC * hDC, HGLRC * hRC) { PIXELFORMATDESCRIPTOR pfd; int format; // get the device context (DC) *hDC = GetDC( hWnd ); // set the pixel format for the DC ZeroMemory( &pfd, sizeof( pfd ) ); pfd.nSize = sizeof( pfd ); pfd.nVersion = 1; pfd.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER; pfd.iPixelType = PFD_TYPE_RGBA; pfd.cColorBits = 24; pfd.cDepthBits = 16; pfd.iLayerType = PFD_MAIN_PLANE; format = ChoosePixelFormat( *hDC, &pfd ); SetPixelFormat( *hDC, format, &pfd ); // create and enable the render context (RC) *hRC = wglCreateContext( *hDC ); wglMakeCurrent( *hDC, *hRC ); } void DisableOpenGL(HWND hWnd, HDC hDC, HGLRC hRC) { wglMakeCurrent( NULL, NULL ); wglDeleteContext( hRC ); ReleaseDC( hWnd, hDC ); }

  • How to determine the timezone that an email was sent from in C#

    - by John Sibly
    Can anyone recommend a way to determine the timezone that an email was sent from in C#? Looking at the header information of an email includes information like: Received: from mail-ew0-f211.google.com (123.85.219.211) by UKExchange (10.1.10.99) with Microsoft SMTP Server id 1.2.345.6; Tue, 13 Apr 2010 14:26:24 +0100 Received: by ewy3 with SMTP id 3so288857ewy.6 for <[email protected]>; Tue, 13 Apr 2010 06:26:23 -0700 (PDT) MIME-Version: 1.0 Received: by 10.103.213.2 with HTTP; Tue, 13 Apr 2010 06:26:23 -0700 (PDT) X-Originating-IP: [83.244.243.210] Date: Tue, 13 Apr 2010 14:26:23 +0100 Received: by 10.103.3.17 with SMTP id f17mr3087878mui.123.1271165183473; Tue, 13 Apr 2010 06:26:23 -0700 (PDT) There are a number of "Received: from" and "Received: by" keys with a date, time and timezone indicated on the end. Which one of these should I attempt to parse? Is this a reliable way to figure out the sender's timezone, or anyone recommend a better way?

  • C# Dynamic Query Without A Database Model

    - by hitopp
    I have been searching the web for a solution to dynamic queries. I have found many different solutions (e.g. Linq to Sql, Dynamic Linq Expressions, Dynamic Query), but all of these solutions involve some sort of previous knowledge of the database (like a model in code). Maybe what I am asking is way off the deep end, but is there any possible way to dynamically query a database without a model? For example, a database has a Customers table with the following columns: CustomerID Name FavoriteColor I want to create a query as SELECT Name FROM Customers WHERE @0 = @1, where the two placeholders are populated dynamically. The resulting data does not tie to a model class and I would prefer to use some sort of framework to build the queries, not simple string concatenation. The System.Linq.Dynamic namespace came really close to fulfilling this request, but it uses a database model. I realize this is crazy, but I was just curious.

  • Getting specific values with regex [JAVA, ANDROID]

    - by David
    I need to knowingly isolate each row of the vcard and get its value. For instance, I want to get "5555" from X-CUSTOMFIELD. So far, my thoughts are: "X-CUSTOMFIELD;\d+" I have been looking at some tutorials and I am a little confused with what function to use? What would my regex above return? Would it give me the whole line or just the numerical part (5555)? I was thinking I i get the whole row, I can use substring to get the digits? BEGIN:VCARD VERSION:2.1 N:Last;First; FN:First Last TEL;HOME;VOICE:111111 TEL;MOBILE;VOICE:222222 X-CUSTOMFIELD;5555 END:VCARD

  • Netbeans GUI Form corrupted?

    - by hubpages-my
    I was making a java gui application through netbeans IDE. All was working fine but yesterday when I opened the form in Netbeans, it said that the form had been corrupted and it could only open that form in read-only mode. When I opened that form in read-only mode, I found that the code was incomplete as severals lines of coding wasn't there at the end. Could anybody tell me how to recover the form. The form is perfect in lookwise but the generated code is incomplete. The code is too long to write it again. The Netbeans told me to get help from http://wiki.netbeans.org/FormGuardedBlockError but I didn't find any helpful information there.

  • Last Observation Carried Forward In a data frame?

    - by Tal Galili
    Hi all, I wish to implement a "Last Observation Carried Forward" for a data set I am working on which has missing values at the end of it. Here is a simple code to do it (question after it): LOCF <- function(x) { # Last Observation Carried Forward (for a left to right series) LOCF <- max(which(!is.na(x))) # the location of the Last Observation to Carry Forward x[LOCF:length(x)] <- x[LOCF] return(x) } # example: LOCF(c(1,2,3,4,NA,NA)) LOCF(c(1,NA,3,4,NA,NA)) Now this works great for simple vectors. But if I where to try and use it on a data frame: a <- data.frame(rep("a",4), 1:4,1:4, c(1,NA,NA,NA)) a t(apply(a, 1, LOCF)) # will make a mess It will turn my data frame into a character matrix. Can you think of a way to do LOCF on a data.frame, without turning it into a matrix? (I could use loops and such to correct the mess, but would love for a more elegant solution) Cheers, Tal

  • PHP search multidimensional array for value, then place that element at start of array

    - by BobFlemming
    I need to search this array: cars - [0] -make : Ford -model: Escort -year: 1991 [1] -make: Honda -model: Civic -year: 1996 [2] -make: Vauxhall -model: Astra -year: 1972 And if (for example) the model is "Civic" , place that 'car' at position 0. So the end array would be like: cars - [0] -make: Honda -model: Civic -year: 1996 [1] -make : Ford -model: Escort -year: 1991 [2] -make: Vauxhall -model: Astra -year: 1972 I've tried some usort variations: function typeSort($a, $b) { if ($a['model'] == 'Civic' ) { return 0; } return ($a['model'] < $b['model']) ? -1 : 1; } but this is just returning 1

  • SSRS and hiding other selections once a parameter is selected

    - by KristiLee
    I am learning SSRS so this is probably an extremely easy solution. I have a bunch of reports that were rebuilt to match some old Access reports. For each report, we have to be able to run Current, Last, Next or Adhoc dates. Is there an easy way if a user selects Adhoc to then show the parameters selections for Start and End Date for the Adhoc selection? Right now, I have people who select Current and then go and put in dates. WHERE (:AGNT='--AllNoFilter--' OR AGNT =:AGNT) AND (:DateRunOption <> 'CM' OR TO_CHAR(MONTH_END_DT, 'Month YYYY') = TO_CHAR(CURRENT_DATE, 'Month YYYY')) AND (:DateRunOption <> 'LM' OR TO_CHAR(MONTH_END_DT, 'Month YYYY') = TO_CHAR(ADD_MONTHS(CURRENT_DATE, -1), 'Month YYYY')) AND (:DateRunOption <> 'AD' OR MONTH_END_DT>= :BeginDateFrom) AND (:DateRunOption <> 'AD' OR MONTH_END_DT<= :BeginDateTo) Thank you for any assistance you can provide

  • Sintra app in a gem

    I have a Sinatra application I've created and I'd like to package it as a gem-based binary. I have my gemspec and gem set up to generate a suitable executable that points to the my_sinatra_app.rb (which is executable) but the sinatra server never runs.

  • Rails - Trying to query from a date range...everything from today

    - by ChrisWesAllen
    I'm trying to figure the best way to query a date range from rails...I looked around on Google but am unsure about how to use this syntax. I have a Model that has various events and I like to add to my find condition a caveat that should only show events where the field :st_date is today or later, in effect only show me data that is current, nothing that happened before today. I ran into a problem because I have no end date to stop the query, I want to query everything from today to next month. I was thinking something like @events = Event.find(:all, :conditions => ["start_date between ? and ?", date.Today, date.next_month.beginning_of_month]) but I get the error undefined local variable or method `date'...... Do I need do anything particular to use the Date class? Or is there something wrong with my query syntax? I would really appreciate any help.

  • If you were developing shareware softwares for windows, would you target the .Net Framework or use n

    - by bohoo
    For the sake of the question, by 'shareware' I mean a software which is relatively small in size (up to few dozens of mb) and available for download and evaluation through a web site. I'm asking this question, because I don't understand something regarding the current state of windows commercial desktop development. It seems to me that: There is no reliable statistic regarding the extent of windows systems with .Net Framework installed. It makes no sense to force the end user to install the 20-60mb .Net for an application which may be smaller. Applications conforms to the term 'shareware' above have a big share on the win os market. Much of them don't need the capabilities of low level languages like c++, and therefore ideally they should be developed with a RAD enviroment. So, One would suppose there will be a blossom of RAD enviroments for native win code. But I know about only one - Delphi, and Delphi is so unpopular. How is that?

  • PNRP + dont see Global_ on Windows 7

    - by schmoopy
    Hi, Im trying to test out PNRP in a simple app that either registers or resolves. On my Vista machine when i run 'netsh p2p pnrp cloud show list' .... I see Global_ When i try this from my Windows 7 machine i do not see Global_ i only have LinkLocal_... I can see i have an IPV6 address on the Windows 7 machine (via ipconfig) I may not just understand it enough yet - very poorly documented and most of the documentation is from Orca, 2007,etc. Makes me wonder if PNRP will just end up being another uddi.microsoft.com (i know they are nothing alike, but my point is...)

  • sort array with special characters in php

    - by Enkay
    I have an array I'm trying to asort using php. The problem is that the array has accented characters in it and needs to be sorted using "french" rules. cote < côte < coté < côté I've tried many things, like using php collators, but I get the following error : PHP Fatal error: Class 'Collator' not found I've also tried to set locale but it didn't do anything so I'm not sure I was doing it right, or if I need to isntall the locale. I'm a little confused. I'm using PHP 5.2.4 if that helps. If I use asort without anything, it puts all the words with accented characters at the end. Thanks.

  • Running The JVM From Within An MXML Component

    - by Joshua
    Thinking outside of the box here... What possible basic approaches could be taken in an effort to create a Flex component that could run Java? I know I can easily use flex to browse to or launch a Java app, but there are things I can only do if I can run the Java from WITHIN an MXML Component. I the strictest sense, I know it's not impossible (ie: if you had all the source code for flex and for the jvm), but what's the least impractical means to this end? Showcase your creativity.

  • Is there a chance that sending an email via a thread could ever fail to complete?

    - by Benjamin Dell
    I have a project where I send a couple of emails via a seperet thread, to speed up the process for the end-user. It works successfully, but i was just wondering whether there were any potfalls that i might not have considered? My greatest fear is that the user clicks a button, it says that the message has been sent (as it will have been sent to the thread for sending) but for some reason the thread might fail to send it. Are there any situations where a thread could be aborted prematurely? Please note, that i am not talking about network outages or obvious issues with an email recipient not existing. For simplicites sake please assume that the connect is up, the mail server alive and the recipient valid. Is it possible, for example, for the thread to abort prematurely if the user kills the browser before the thread has completed? This might be a silly question, but i just wanted to make sure i knew the full ramifications of using a thread in this manner. Thanks, in advance, for your help.

  • How to estimate the quality of a web page?

    - by roddik
    Hello, I'm doing a university project, that must gather and combine data on a user provided topic. The problem I've encountered is that Google search results for many terms are polluted with low quality autogenerated pages and if I use them, I can end up with wrong facts. How is it possible to estimate the quality/trustworthiness of a page? You may think "nah, Google engineers are working on the problem for 10 years and he's asking for a solution", but if you think about it, SE must provide up-to-date content and if it marks a good page as a bad one, users will be dissatisfied. I don't have such limitations, so if the algorithm accidentally marks as bad some good pages, that wouldn't be a problem.

  • Sending file over socket

    - by johannix
    I'm have a problem sending data as a file from one end of a socket to the other. What's happening is that both the server and client are trying to read the file so the file never gets sent. I was wondering how to have the client block until the server's completed reading the file sent from the client. I have this working with raw packets using send and recv, but figured this was a cleaner solution... Client: connects to server creating socket connection creates a file on socket and sends data waits for file from server Server: waits for file from client Complete interraction: client sends data to server server sends data to client
