  • Rails Authlogic authentication method

    - by Rabbott
    Within Authlogic, is there a way that I can add conditions to the authentication method? I know by using the find_by_login_method I can specify another method to use, but when I use this I need to pass another parameter since the find_by_login_method method only passes the parameter that is deemed the 'login_field'. What I need to do is check something that is an association of the authentic model.. Here is the method I want to use # make sure that the user has access to the subdomain that they are # attempting to login to, subdomains are company names def self.find_by_email_and_company(email, company) user = User.find_by_email(email) companies = [] user.brands.each do |b| companies << b.company.id end user && companies.include?(company) end But this fails due to the fact that only one parameter is sent to the find_by_email_and_company method. The company is actually the subdomain, so in order to get it here I am just placing it in a hidden field in the form (only way I could think to get it to the model) Is there a method I can override somehow..?

  • Replace strings differently depending if is enclosed in braces or not.

    - by peroyomas
    I want to replace all instances of an specific words between braces with something else, unless it is written between double braces, while it should show as is it was written with single braces without the filter. I have tried a code but only works for the first match. The rest are shown depending of the first one: $foo = 'a {bar} b {{bar}} c {bar} d'; $baz = 'Chile'; preg_match_all( '/(\{?)\{(tin)\}(\}?)/i', $foo, $matches, PREG_SET_ORDER ); if ( !empty($matches) ) { foreach ( (array) $matches as $match ) { if( empty($match[1]) && empty($match[3])) { $tull = str_replace( $match[0], $baz, $foo ); } else { $tull = str_replace( $match[0], substr($match[0], 1, -1), $foo ) ; } } } echo $tull;

  • Making linq avoid using in memory filtering where possible

    - by linqmonkey
    Consider the these two LINQ2SQL data retrieval methods. The first creates a 'proper' SQL statement that filters the data, but requires passing the data context into the method. The second has a nicer syntax but loads the entire list of that accounts projects, then does in memory filtering. Is there any way to preserve the syntax of the second method but with the performance advantage of the first? public partial class Account { public IQueryable<Project> GetProjectsByYear(LinqDataContext context, int year) { return context.Projects.Where(p => p.AccountID==this.AccountID && p.Year==year).OrderBy(p => p.ProjectNo) } public IQueryable<Project> GetProjectsByYear(int year) { return this.Projects.Where(p => p.Year==year).OrderBy(p => p.ProjectNo).AsQueryable() } }

  • sIFR: dynamically inserting umlaut causes trouble

    - by arold
    Hi, let me state cleary at the beginning that I know about the embedding issue in flash. So, to the point. If sIFR replaces an umlaut (ä,ö,ü) which is hard coded in the HTML file everythings works fine. But when I want to insert it dynamically it is not displayed. I played around with charset options to specifiy the javascript file i'm referencing but it doesnt change a thing. Here's JavaScript and sIFR code: sIFR.replacements["#image-counter span"][0].replaceText("ö"); I tried as well to replace "ö" by "&ouml;" and "&#246" but this doesnt work around it either. Any ideas?

  • Swap byte 2 and 4 from integer

    - by czar x
    I had this interview question - Swap byte 2 and byte4 within an integer sequence. Integer is a 4byte wide i.e. 32 bits My approach was to use char *pointer and a temp char to swap the bytes. For clarity i have broken the steps otherwise an character array can be considered. unsigned char *b2, *b4, tmpc; int n = 0xABCD; b2 = &n; b2++; b4 = &n; b4 +=3; ///swap the values; tmpc = *b2; *b2 = *b4; *b4 = tmpc; Any other methods?

  • ModX navigation menu with "wayfinder" snippet

    - by user1219432
    I have a main navigation at the top of the site. And a subnavigation at left of my site. For example: At the top there are these topics: Cars | Trees | Jobs | ... So when you click on "Jobs" there should be the subnavigation of "Jobs" at left, like... Construction Jobs Engineering Jobs Retail Jobs ... The first (top) navigation is easy to achieve: [[!Wayfinder? &startId=0 &level=1 ]] How can I realize the second navigation, so that only the documents are listed that are under the parent document?

  • fastest in objC: IsEqualToString:@"" or length > 0?

    - by Cœur
    I'd like to know which one is fastest for testing a non-empty NSString for iOS 4.0+ (iPhone 3G). Note: the strings to test will be 99% of the time from 2 to 100 chars length. if ([foo length] > 0) or if ([foo isEqualToString:@""] == NO && foo != nil) I think it depends if isEqualToString: compares the length first (and in that case first way is faster) or if isEqualToString: compares first character of strings first (and in that case second way might be faster). ps: I already know isEqualToString: is faster than isEqual: which is itself faster than compare:.

  • problem with generating PDF and session_start()

    - by gillian
    Hi All, I've been using PDF class produced by R&OS successfully in a number of recent developments. I'd like to use it in a page that performs a database query before generating a PDF (it's basically a summary of the session, so I'm using session_id() as part of the query) All is fine if I run this in Firefox - not fine in IE. I think the loading of session_start() is doing something with headers that's upsetting IE as it appears unable to load the page (comment off session_start and the page loads fine). I'm getting a little concerned as, on further investigation, it appears that R&OS is not supported ... bad newbie learning experience and I really don't want to have to try adopt another class system this late in the day. Have you any thoughts as to what I could try next? Thankx G

  • How to extract a submatrix from a matrix .. ?

    - by ZaZu
    Hello, I have a matrix in a txt file and I want to load the matrix based on my input of number of rows and columns For example, I have a 5 by 5 matrix in the file. I want to extract a 3 by 3 matrix, how can I do that ? I created a nested loop using : FILE *sample sample=fopen("randomfile.txt","r"); for(i=0;i<rows;i++){ for(j=0;j<cols;j++){ fscanf(sample,"%f",&matrix[i][j]); } fscanf(sample,"\n",&matrix[i][j]); } fclose(sample); Sadly the code does not work .. If I have this matrix : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 3.00 4.00 23.00 5.00 2.00 352.00 6.00 And inputting 3 for rows and 3 for columns, I get : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 Which is obviously wrong , its reading line by line rather than skipping the unmentioned column ... What am I doing wrong ? Thanks !

  • Constructors + Dependency Injection

    - by Sunny
    If I am writing up a class with more than 1 constructor parameter like: class A{ public A(Dependency1 d1, Dependency2 d2, ...){} } I usually create a "argument holder"-type of class like: class AArgs{ public Dependency1 d1 { get; private set; } public Dependency2 d2 { get; private set; } ... } and then: class A{ public A(AArgs args){} } Typically, using a DI-container I can configure the constructor for dependencies & resolve them & so there is minimum impact when the constructors need to change. Is this considered an anti-pattern and/or any arguments against doing this?

  • Crossplatform development for iPhone & Android

    - by LeonixSolutions
    As far as I can see there doesn't seem to any mature environment for crossplatform development for iPhone & Android slate (but feel free to correct me). I don't know Ipad, I must admit. Any reason why plain Java wouldn't cut it? (maybe underlying things like database (I am not too concerned with hardware)) I am thinking to try to make everything browser based, although that won't get around the d/b & h/w issues, unless there is JS framework that does so. Any advice?

  • Image URL has the contentType "text/html"

    - by user1503025
    I want to implement a method to download Image from website to laptop. public static void DownloadRemoteImageFile(string uri, string fileName) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); if ((response.StatusCode == HttpStatusCode.OK || response.StatusCode == HttpStatusCode.Moved || response.StatusCode == HttpStatusCode.Redirect) && response.ContentType.StartsWith("image", StringComparison.OrdinalIgnoreCase)) { //if the remote file was found, download it using (Stream inputStream = response.GetResponseStream()) using (Stream outputStream = File.OpenWrite(fileName)) { byte[] buffer = new byte[4096]; int bytesRead; do { bytesRead = inputStream.Read(buffer, 0, buffer.Length); outputStream.Write(buffer, 0, bytesRead); } while (bytesRead != 0); } } } But the ContentType of request or response is not "image/jpg" or "image/png". They're always "text/html". I think that's why after I save them to local, they has incorrect content and I cannot view them. Can anyone has a solution here? Thanks
