  • django getting current user id

    - by dana
    hello, i have a mini app where users can login, view their profile, and follow each other. 'Follow' is a relation like a regular 'friend' relationship in virtual communities, but it is not necessarily reciprocal, meaning that one can follow a user, without the need that the user to be following back that person who follows him. my problem is: if i am a logged in user, and i navigate to a profile X, and push the button follow, how can i take the current profile id ?(current profile meaning the profile that I, the logged in user, am viewing right now.) the view: def follow(request): if request.method == 'POST': form = FollowForm(request.POST) if form.is_valid(): new_obj = form.save(commit=False) new_obj.initiated_by = request.user u = User.objects. what here? new_obj.follow = u new_obj.save() return HttpResponseRedirect('.') else: form = FollowForm() return render_to_response('followme/follow.html', { 'form': form, }, context_instance=RequestContext(request)) thanks in advance!

  • In Sinatra, best way to serve iPhone layout vs. normal layout?

    - by Doug
    I'm writing a Sinatra app which needs to render different layouts based on whether the user is using an iPhone or a regular browser. I can detect the browser type using Rack-Mobile-Detect but I'm not sure of the best way to tell Sinatra which layout to use. Also, I have a feeling that how I choose to do this may also break page caching. Is that true? Example code: require 'sinatra/base' require 'haml' require 'rack/mobile-detect' class Orca < Sinatra::Base use Rack::MobileDetect helpers do def choose_layout if request.env['X_MOBILE_DEVICE'] == :iPhone # use iPhone layout else # use normal layout end end end before do # should I use a before filter? choose_layout() end get '/' do haml :home # with proper layout end end #Class Orca

  • Regex for Searching for Text Not Preceeded By a Specific String

    - by James
    Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

  • More HtAccess Rewrite Rules

    - by pws5068
    Greetings all, I need help combining some htaccess rewrites, these crazy regular expressions screw with my head. So I have a folder structure something like this: /www/mysite.com/page/member/friends.php /www/mysite.com/page/video/videos.php /www/mysite.com/page/messages/inbox.php The URLs get rewritten to this: mysite.com/member/friends.php mysite.com/video/videos.php mysite.com/messages/inbox.php (Notice the /page/ folder is hidden in the url, but I keep it on the server for better file organization) The rewrite rules look something like this: (I'm new so correct me if they are flawed) RewriteRule ^video/(.*)$ /page/video/$1 [NC] RewriteRule ^member/(.*)$ /page/member/$1 [NC] RewriteRule ^messages/(.*)$ /page/messages/$1 [NC] Now, I also need to do a completely different rewrite to a file called lobby.php inside of the member folder: After the original rewrites, a sample url looks like: mysite.com/member/lobby.php?member=pws5068 I need a new rewrite to make it look like this: mysite.com/pws5068 Thank you for bearing with my super-long question here. How can I make this happen?

  • Passing functions as arguements in Matlab

    - by Dave
    Hi, I'm trying to write a function that is gets two arrays and the name of another function as arguements. e.g. main.m: x=[0 0.2 0.4 0.6 0.8 1.0]; y=[0 0.2 0.4 0.6 0.8 1.0]; func2(x,y,'func2eq') func 2.m : function t =func2(x, y, z, 'func') //"unexpected matlab expression" error message here t= func(x,y,z); func2eq.m: function z= func2eq(x,y) z= x + sin(pi * x)* exp(y); Matlab tells gives me the above error message. I've never passed a function name as an arguement before. Where am I going wrong? p.s. sorry about the formatting of code above, I can't seems to get SO to show parts of the code as code.

  • Referencing View directory in asp.net mvc

    - by ooo
    i have some html files as part of a regular website that has been ported over to asp.net mvc. In my code i need to read and write these html files and stick them in a tinymce editor To be able to read and write this file from disk in the past i had a hard coded path but this doesn't seem to work in asp.net mvc unless i do something like this: Writing: string _urlDirectory = @"c:\hosting\MySite\Views\Members\newsletters\test.html"; System.IO.File.WriteAllText(_urlDirectory, htmlData_); Reading: string url = @"c:\hosting\MySite\Views\Members\newsletters\test.html"; var req = WebRequest.Create(url); var response = req.GetResponse(); StreamReader sr = new StreamReader(response.GetResponseStream()); string htmlData_ = sr.ReadToEnd(); i am moving my site from one data center to another and the directory structure is changing. instead of just changing the hard coded path to another hard coded path i wanted to see if there was a more relative way to reference these files.

  • The conceptual process of populating related tables in a database (MySql) from a CSV file

    - by user322772
    I'm new to relational databases and all the material I've read covered primary and foreign keys, normal forms, and joins but left out to populate the database once it's created. How do you import a CSV file so the fields match their related table? Say you were tying to build a beer database and had a CSV file with each line as a record. Header: brewer, beer_name, country, city, state, beer_category, beer_type, alcohol_content Record 1: Anheuser-Busch, Budweiser, United States, St. Louis, Mo, Pale lager, Regular, 5.0% Record 2: Anheuser-Busch, Bud Light, United States, St. Louis, Mo, Pale lager Light, 4.2% Record 3: Miller Brewing Company, Miller Lite, United States, Milwaukee, WI, Pale lager, Light, 4.2% You can create a "Brewer" table and a "Beer" table. When importing how does you connect the primary keys between the tables?

  • How can I utilize or mimic Application OnStart in an HttpModule?

    - by Sailing Judo
    We are trying to remove the global.asax from our many web applications in favor of HttpModules that are in a common code base. This works really well for many application events such as BeginRequest and PostAuthentication, but there is no Application Start event exposed in the HttpModule. I can think of a couple of smelly ways to overcome this deficit. For example, I can probably do this: protected virtual void BeginRequest(object sender, EventArgs e) { Log.Debug("Entered BeginRequest..."); var app = HttpContext.Current.Application; var hasBeenSet app["HasBeenExecuted"] == null ? false : true; if(!hasBeenSet) { app.Lock(); // ... do app level code app.Add("HasBeenSet", true); app.Unlock(); } // do regular begin request stuff ... } But this just doesn't smell well to me. What is the best way to invoke some application begin logic without having a global.asax?

  • GetDate in a string in c#

    - by Doncho
    Hi, I'm having some trouble using regular expression to get date in a string. Example : string text = "75000+ Sept.-Oct. 2004"; MatchCollection dates = Regex.Matches(text, @"[0-9]{5,}[+][\s](jan|feb|fev|mar|apr|avr|may|mai|jun|jui|jul|jui|aug|aoû|sept|oct|nov|dec)[\.][\-](jan|feb|fev|mar|apr|avr|may|mai|jun|jui|jul|jui|aug|aoû|sept|oct|nov|dec)[\.]\s[0-9]{4}", RegexOptions.IgnoreCase); This code is matching with my current string but i would like to get in my matchcollection, "Sept 2004" and "Oct 2004" in order to parse it in 2 datetime. If anyone have any idea, thanks a lot.

  • In MongoDB, how can I replicate this simple query using map/reduce in ruby?

    - by Matthew Rathbone
    Hi, So using the regular MongoDB library in Ruby I have the following query to find average filesize across a set of 5001 documents: avg = 0 total = collection.count() Rails.logger.info "#{total} asset creation stats in the system" collection.find().each {|row| avg += (row["filesize"] * (1/total.to_f)) if row["filesize"]} Its pretty simple, so I'm trying to do the same using map/reduce as a learning exercise. This is what I came up with: map = 'function(){emit("filesizes", {size: this.filesize, num: 1});}' reduce = 'function(k, vals){ var result = {size: 0, num: 0}; for(var x in vals) { var new_total = result.num + vals[x].num; result.num = new_total result.size = result.size + (vals[x].size * (vals[x].num / new_total)); } return result; }' @results = collection.map_reduce(map, reduce) However the two queries come back with two different results! What am I doing wrong?

  • Backing up locally modified and new source files

    - by eran
    I'm wondering how other programmers are backing up changes that are not under source control yet, be it new files or modified ones. I'm mostly referring to medium size jobs - hardly worth the effort of making a private branch, but taking more than a day to complete. This is not a vendor-specific question - I'd like to see if various products have different solutions to the problem. I'd appreciate answers referring to SVN and distributed SCCs, though. I'm mostly wondering about that latters (Mercurial, GIT etc.) - it's great that you have your own local repo, but do you back it up on a regular basis along with your source files? Note - I'm not asking about a general backup strategy. For that, we have IT. I'm seeking the best way to keep locally modified stuff backed-up before they are checked back into the main repo.

  • C# Entity Framework Base Repository

    - by Andy
    I'm trying to create a base repository for use with Entity Framework 4.0 and having some trouble. In this code below, why is it not possible to do this in one line? public IEnumerable<T> GetAll<T>(Expression<Func<T, bool>> filter) { IEnumerable<T> allCustomers = this.GetAll<T>(); IEnumerable<T> result = allCustomers.Where(filter.Compile()); return result; } Won't this result in 2 SQL statements: one without a where clause that retrieves all rows, and one with a where clause that only retrieves the rows that match the predicate? How can this be done with a single SQL statement? I can't get it to compile if I try to cast the filter.Compile() to Func<Customer, bool>. Thanks, Andy

  • parse youtube video id using preg_match

    Hi, I am attempting to parse the video ID of a youtube URL using preg_match. I found a regular expression on this site that appears to work; (?<=v=)[a-zA-Z0-9-]+(?=&)|(?<=[0-9]/)[^&\n]+|(?<=v=)[^&\n]+ As shown in this pic; http://i.imgur.com/SQJW2.jpg My PHP is as follows, but it doesn't work (gives Unknown modifier '[' error)... <? $subject = "http://www.youtube.com/watch?v=z_AbfPXTKms&NR=1"; preg_match("(?<=v=)[a-zA-Z0-9-]+(?=&)|(?<=[0-9]/)[^&\n]+|(?<=v=)[^&\n]+", $subject, $matches); print "<pre>"; print_r($matches); print "</pre>"; ?> Cheers

  • Regex and unicode

    - by dbr
    I have a script that parses the filenames of TV episodes (show.name.s01e02.avi for example), grabs the episode name (from the www.thetvdb.com API) and automatically renames them into something nicer (Show Name - [01x02].avi) The script works fine, that is until you try and use it on files that have Unicode show-names (something I never really thought about, since all the files I have are English, so mostly pretty-much all fall within [a-zA-Z0-9'\-]) How can I allow the regular expressions to match accented characters and the likes? Currently the regex's config section looks like.. config['valid_filename_chars'] = """0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@£$%^&*()_+=-[]{}"'.,<>`~? """ config['valid_filename_chars_regex'] = re.escape(config['valid_filename_chars']) config['name_parse'] = [ # foo_[s01]_[e01] re.compile('''^([%s]+?)[ \._\-]\[[Ss]([0-9]+?)\]_\[[Ee]([0-9]+?)\]?[^\\/]*$'''% (config['valid_filename_chars_regex'])), # foo.1x09* re.compile('''^([%s]+?)[ \._\-]\[?([0-9]+)x([0-9]+)[^\\/]*$''' % (config['valid_filename_chars_regex'])), # foo.s01.e01, foo.s01_e01 re.compile('''^([%s]+?)[ \._\-][Ss]([0-9]+)[\.\- ]?[Ee]([0-9]+)[^\\/]*$''' % (config['valid_filename_chars_regex'])), # foo.103* re.compile('''^([%s]+)[ \._\-]([0-9]{1})([0-9]{2})[\._ -][^\\/]*$''' % (config['valid_filename_chars_regex'])), # foo.0103* re.compile('''^([%s]+)[ \._\-]([0-9]{2})([0-9]{2,3})[\._ -][^\\/]*$''' % (config['valid_filename_chars_regex'])), ]

  • User settings mechanism for Yii

    - by Peterim
    Hi guys! I need some help with user settings mechanism for my Yii-based application. I've created the following db structure to store user settings: table user with the following fields id | username | email | etc. table settingslist (to store a list of all possible settings with descriptions) with the following fields id | code | name | description table settings (to store all user settings) with the following fields id | userid | settingslistcode | value Now I'm stuck with the form which allows user to change his settings. I had to deal before with the regular models (i.e. for posts, comments, etc.) where every new model had only one row in the database (Post model - id | title | body |) with the certain amount of attributes (fields of the table). But now I need to store user settings in 10-15 rows and I don't know how to apply Yii model mechanism to work with this, so I can retrieve those settings in a single form (so user could change his preferences). Any suggestions are greatly appreciated. Thank you!

  • How to binding to bit datatype in SQL to Booleans/CheckBoxes in ASP.NET MVC 2 with DataAnnotations

Cannot convert lambda expression to delegate type 'System.Func<Framework.Models.customer,bool>' because some of the return types in the block are not implicitly convertible to the delegate return type Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?) Please suggest me how can I solve this problem? Thanks in advance.

  • NSString sizeWithAttributes: Inaccuracy

    - by dave-gennel
    I want to know the width of an NSString displayed on the screen in pixels. So I can fit an NSTextField its bounds to be exactly the length of the string itself. So I used IB's "Label" NSTextField and for those who don't know what I mean, I got a label with title "Label", font "Lucida Grande 13px", not selectable, not editable, regular size, no background and according to IB its width is 38px wide. If I want to get its width programatically I use [@"Label" sizeWithAttributes: [NSDictionary dictionaryWithObject: [NSFont fontWithName: @"Lucida Grande" size: 13] forKey: NSFontAttributeName]].width Which will give me 33.293457 . So that's about 5 px of the real width..

  • What's the fastest way to strip and replace a document of high unicode characters using Python?

    - by Rhubarb
    I am looking to replace from a large document all high unicode characters, such as accented Es, left and right quotes, etc., with "normal" counterparts in the low range, such as a regular 'E', and straight quotes. I need to perform this on a very large document rather often. I see an example of this in what I think might be perl here: http://www.designmeme.com/mtplugins/lowdown.txt Is there a fast way of doing this in Python without using s.replace(...).replace(...).replace(...)...? I've tried this on just a few characters to replace and the document stripping became really slow.

  • Regex for finding valid sphinx fields

    - by mlissner
    I'm trying to validate that the fields given to sphinx are valid, but I'm having difficulty. Imagine that valid fields are cat, mouse, dog, puppy. Valid searches would then be: @cat search terms @(cat) search terms @(cat, dog) search term @cat searchterm1 @dog searchterm2 @(cat, dog) searchterm1 @mouse searchterm2 So, I want to use a regular expression to find terms such as cat, dog, mouse in the above examples, and check them against a list of valid terms. Thus, a query such as: @(goat) Would produce an error because goat is not a valid term. I've gotten so that I can find simple queries such as @cat with this regex: (?:@)([^( ]*) But I can't figure out how to find the rest. I'm using python & django, for what that's worth.

  • SQL statement HAVING MAX(some+thing)=some+thing

    - by Andreas
    I'm having trouble with Microsoft Access 2003, it's complaining about this statement: select cardnr from change where year(date)<2009 group by cardnr having max(time+date) = (time+date) and cardto='VIP' What I want to do is, for every distinct cardnr in the table change, to find the row with the latest (time+date) that is before year 2009, and then just select the rows with cardto='VIP'. This validator says it's OK, Access says it's not OK. This is the message I get: "you tried to execute a query that does not include the specified expression 'max(time+date)=time+date and cardto='VIP' and cardnr=' as part of an aggregate function." Could someone please explain what I'm doing wrong and the right way to do it? Thanks

  • Suggestion for creating custom sound recognition software to toggle audio

    - by Parrot owner
    I need to develop a program that toggles a particular audio track on or off when it recognizes a parrot scream or screech. The software would need to recognize a particular range of sounds and allow some variations in the range (as a parrot likely won't replicate its sreeches EXACTLY each time). Example: Bird screeches, no audio. Bird stops screeching for five seconds, audio track praising the bird plays. Regular chattering needs to be ignored completely, as it is not to be discouraged. I've heard of java libraries that have speech recognition with dictionaries built in, but the software would need to be taught the particular sounds that my particular parrot makes - not words or any random bird sound. In addition as I mentioned above, it would need to allow for slight variation in the sound, as the screech will likely never be 100% identical to the recorded version. What would be the best way to go about this/what language should I look into?

  • Selenium not finding LiveValidation text.

    - by McNabbToSkins
    I am using the Selenium IDE to test some of my web development. I am using the JQuery LiveValidation in my code. I have an input box with some javascript behind it that will do a regular expresson and either ouput "OK" or "Error" next to the input text box based on what the user has entered. For some reason when testing with selenium the LiveValidation will not get triggered no matter what I do and therefore I can not test it. When I do it manually it works great. Has anyone run into this problem before? Any help would be appreciated.

  • Testing for security vulnerabilities on web applications

    - by Moak
    A lot of companies use CMS software that updates on the regular, often they are security fixes, implying that the previous version have security vulnerabilities. But most clients never upgrade this, or even the CMS has been modified so that an update would break the site. Are there sites that document these exploits, and instruct how to test for them? Or does this information not even get published? (in order not to have people try to exploit them) Also is there a generic php/js based check list to prevent hack attempts? I know about SQL injections and XSS, but I'm sure that there are more threats out there. Peace

  • What lessons can you learn from software maintanence?

    - by Vasil Remeniuk
    Hello everyone, In the perfect world, all the software developers would work with the cutting edge technologies, creating systems from the scratch. In the real life, almost all of us have to maintain software from time to time (unlucky ones do it on a regular basis). Personally I first 2 years of my career was fixing bugs in the company that no longer exists (it has been taken up by Oracle). And probably the biggest lesson I've learned that time - despite of the pressure, always try to get as much information about the domain as possible (even if it's irrelevant to fixing a specific bug or adding a feature) - abstract domain knowledge doesn't lose value as fast as knowledge about trendy frameworks or methodologies. What lessons have you learned from maintenance?
