  • This is more a matlab/math brain teaser than a question

    - by gd047
    Here is the setup. No assumptions for the values I am using. n=2; % dimension of vectors x and (square) matrix P r=2; % number of x vectors and P matrices x1 = [3;5] x2 = [9;6] x = cat(2,x1,x2) P1 = [6,11;15,-1] P2 = [2,21;-2,3] P(:,1)=P1(:) P(:,2)=P2(:) modePr = [-.4;16] TransPr=[5.9,0.1;20.2,-4.8] pred_modePr = TransPr'*modePr MixPr = TransPr.*(modePr*(pred_modePr.^(-1))') x0 = x*MixPr Then it was time to apply the following formula to get myP , where µij is MixPr. I used this code to get it: myP=zeros(n*n,r); Ptables(:,:,1)=P1; Ptables(:,:,2)=P2; for j=1:r for i = 1:r; temp = MixPr(i,j)*(Ptables(:,:,i) + ... (x(:,i)-x0(:,j))*(x(:,i)-x0(:,j))'); myP(:,j)= myP(:,j) + temp(:); end end Some brilliant guy proposed this formula as another way to produce myP for j=1:r xk1=x(:,j); PP=xk1*xk1'; PP0(:,j)=PP(:); xk1=x0(:,j); PP=xk1*xk1'; PP1(:,j)=PP(:); end myP = (P+PP0)*MixPr-PP1 I tried to formulate the equality between the two methods and seems to be this one. To make things easier, I ignored from both methods the summation of matrix P. where the first part denotes the formula that I used, while the second comes from his code snippet. Do you think this is an obvious equality? If yes, ignore all the above and just try to explain why. I could only start from the LHS, and after some algebra I think I proved it equals to the RHS. However I can't see how did he (or she) think of it in the first place.

  • AVAudioRecorder Won't Record On Device

    - by Dyldo42
    This is my method: -(void) playOrRecord:(UIButton *)sender { if (playBool == YES) { NSError *error = nil; NSString *filePath = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat: @"%d", [sender tag]] ofType:@"caf"]; NSURL *fileUrl = [NSURL fileURLWithPath:filePath]; AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:fileUrl error:&error]; [player setNumberOfLoops:0]; [player play]; } else if (playBool == NO) { if ([recorder isRecording]) { [recorder stop]; [nowRecording setImage:[UIImage imageNamed:@"NormalNormal.png"] forState:UIControlStateNormal]; [nowRecording setImage:[UIImage imageNamed:@"NormalSelected.png"] forState:UIControlStateSelected]; } if (nowRecording == sender) { nowRecording = nil; return; } nowRecording = sender; NSError *error = nil; NSString *filePath = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat: @"%d", [sender tag]] ofType:@"caf"]; NSURL *fileUrl = [NSURL fileURLWithPath:filePath]; [sender setImage:[UIImage imageNamed:@"RecordingNormal.png"] forState:UIControlStateNormal]; [sender setImage:[UIImage imageNamed:@"RecordingSelected.png"] forState:UIControlStateSelected]; recorder = [[AVAudioRecorder alloc] initWithURL:fileUrl settings:recordSettings error:&error]; [recorder record]; } } Most of it is self explanatory; playBool is a BOOL that is YES when it is in play mode. Everything works in the simulator however, when I run it on a device, [recorder record] returns NO. Does anyone have a clue as to why this is happening?

  • H.264 / FLV best practices for HTML

    - by Steve Murch
    I run a website with about 700 videos (And no, it's not porn -- get your mind out of the gutter :-) ). The videos are currently in FLV format. We use the JWPlayer to render those videos. IIS6 hosted. Everything works just fine. As I understand it, H.264 (not FLV and likely not OGG) is the emerging preferred HTML5 video standard. Today, the iPad really only respects H.264 or YouTube. Presumably, soon many more important browsers will follow Apple's lead and respect only the HTML5 tag. OK, so I think I can figure out how to convert my existing videos into the proper H.264 format. There are various tools available, including ffmpeg.exe. I haven't tried it yet, but I don't think that's going to be a problem after fiddling with the codec settings. My question is more about the container itself -- that is, planning graceful transition for all users. What's the best-practice recommendation for rendering these videos? If I just use the HTML5 tag, then presumably any browser that doesn't yet support HTML5 won't see the videos. And if I render them in Flash format via the JWPlayer or some other player, then they won't be playable on the iPad. Do I have to do ugly UserAgent detection here to figure out what to render? I know the JWPlayer supports H.264 media, but isn't the player itself a Flash component and therefore not playable on the iPad? Sorry if I'm not being clear, but I'm scratching my head on a graceful transition plan that will work for current browsers, the iPad and the upcoming HTML5 wave. I'm not a video expert, so any advice would be most welcome, thanks.

  • Can a sub-procedure procedure lock and modify the same rows FOR UPDATE that its calling procedure al

    - by RenderIn
    Will the following code lead to a deadlock or should it work without any problem? I've got something similar and it's working but I didn't think it would. I thought the parent procedure's lock would have resulted in a deadlock for the child procedure but it doesn't seem to be. If it works, why? My guess is that the nested FOR UPDATE is not running into a deadlock because it's smart enough to realize that it is being called by the same procedure that has the current lock. Would this be a deadlock if FOO_PROC was not a nested procedure? DECLARE FOO_PROC(c_someName VARCHAR2) as cursor c1 is select * from awesome_people where person_name = c_someName FOR UPDATE; BEGIN open c1; update awesome_people set person_name = UPPER(person_name); close c1; END FOO_PROC; cursor my_cur is select * from awesome_people where person_name = 'John Doe' FOR UPDATE; BEGIN for onerow in c1 loop FOO_PROC(onerow.person_name); end loop; END;

  • Objective-C memory model

    - by TofuBeer
    I am attempting to wrap my head around one part of the Objective-C memory model (specifically on the iPhone, so no GC). My background is C/C++/Java, and I am having an issue with the following bit of code (also wondering if I am doing this in an "Objective-C way" or not): - (NSSet *) retrieve { NSMutableSet *set; set = [NSMutableSet new]; // would normally fill the set in here with some data return ([set autorelease]); } - (void) test { NSSet *setA; NSSet *setB; setA = [self retrieve]; setB = [[self retrieve] retain]; [setA release]; [setB release]; } start EDIT Based on comments below, the updated retrieve method: - (NSSet *) retrieve { NSMutableSet *set; set = [[[NSMutableSet alloc] initWithCapacity:100] autorelease]; // would normally fill the set in here with some data return (set); } end EDIT The above code gives a warning for [setA release] "Incorrect decrement of the reference count of an object is not owned at this point by the caller". I though that the "new" set the reference count to 1. Then the "retain" call would add 1, and the "release" call would drop it by 1. Given that wouldn't setA have a reference count of 0 at the end and setB have a reference count of 1 at the end? From what I have figured out by trial and error, setB is correct, and there is no memory leak, but I'd like to understand why that is the case (what is wrong with my understanding of "new", "autorelease", "retain", and "release").

  • Ajax/PHP contact form not able to send mail

    - by Steph
    The funny thing is it did work for one evening. I contacted my host, and they are saying there's no reason it should not be working. I have also attempted to test it in Firebug, but it seemed to be sending. And I specifically put the email address (hosted in my domain) on my email safe list, so that is not the culprit either. Would anyone here take a look at it for me? I'd be so grateful. In the header I have: <script type="text/javascript"> $(document).ready(function() { var options = { target: '#alert' }; $('#contactForm').ajaxForm(options); }); $.fn.clearForm = function() { return this.each(function() { var type = this.type, tag = this.tagName.toLowerCase(); if (tag == 'form') return $(':input',this).clearForm(); if (type == 'text' || type == 'password' || tag == 'textarea') this.value = ''; else if (type == 'checkbox' || type == 'radio') this.checked = false; else if (tag == 'select') this.selectedIndex = -1; }); }; </script> Here is the actual form: <form id="contactForm" method="post" action="sendmail.php"> <fieldset> <p>Email Me</p> <div id="fieldset_container"> <label for="name">Your Name:</label> <input type="text" name="name" id="name" /><br /><br /> <label for="email">Email:</label> <input type="text" name="email" id="email" /><br /><br /> <span style="display:none;"> <label for="last">Honeypot:</label> <input type="text" name="last" value="" id="last" /> </span><br /><br /> <label for="message">Comments &amp; Inquiries:</label> <textarea name="message" id="message" cols="" rows=""></textarea><br/> </div> <div id="submit_button"> <input type="submit" name="submit" id="submit" value="Send It" /> </div> </fieldset> </form> <div class="message"><div id="alert"></div></div> Here is the code from my validating page, sendmail.php: <?php // Who you want to recieve the emails from the form.

  • active_admin/formtastic ignoring polymorphic associations

    - by James Maskell
    I'm currently having trouble with the form for a polymorphic association in active_admin in Ruby on Rails. I have three models set up: offices, companies and users. Both companies and users can own an office. My models are set up as follows: class Office < ActiveRecord::Base belongs_to :ownable, :polymorphic => true end class User < ActiveRecord::Base has_many :offices, :as => :ownable end class Company < ActiveRecord::Base has_many :offices, :as => :ownable end active_admin doesn't allow me to edit the owner on its forms, but does show it correctly on the index and show pages (including links to the company or user). I've tried playing with formtastic to manually create the form but have not had any luck - the "ownable" fields just get ignored and everything else renders properly. To be clear: I want to be able to edit the owner of the Office model on the new and edit fields in active_admin. Can anyone offer any help? :)

  • remove an ASIHTTPRequest thread when it is done

    - by user262325
    Hello everyone I have a project in which it runs 5 download threads - (void)fetchThisURLFiveTimes:(NSURL *)url { [myProgressIndicator setProgress:0]; NSLog(@"Value: %f", [myProgressIndicator progress]); [myQueue cancelAllOperations]; [myQueue setDownloadProgressDelegate:myProgressIndicator]; [myQueue setDelegate:self]; [myQueue setRequestDidFinishSelector:@selector(queueComplete:)]; int i; for (i=0; i<5; i++) { ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request setDidFinishSelector:@selector(requestDone:)]; [request setDelegate:self]; [myQueue addOperation:request]; } [myQueue go]; } - (void)requestWentDone:(ASIHTTPRequest *)request { //.. } - (void)queueComplete:(ASINetworkQueue *)queue { NSLog(@"Value: %f", [myProgressIndicator progress]); } I hope to remove a thread when it is done. I do not know where I need to place my codes: requestWentDone:(ASIHTTPRequest *)request or queueComplete:(ASINetworkQueue *)queue I noticed there is no tag property for request, so I added it to ASIHTTPRequest to help me recognize which thread prompts the function reuqestWentDone, I can get the tag of different request, but I do not know how to remove the ASIHTTPRequest thread from myQueue. Welcome any comment Thanks interdev

  • TinyMCE Image Alignment

    - by will.earp.co.uk
    TinyMCE has always been a little difficult to align images. Either the align tag, or adding style="float: left;" has been it solution. Ideally I would just like to add class="left" or class="right" so that I can set the border and margins of the image. Up until now the only way to do this without using the advimage plugin was to insert the image, then select it, the select a style from the style menu. Ideally I should be able to use the align control in the image dialogue to set the alignment class or use the alignment controls on the toolbar when in the main editing window. I have just again started looking at a solution to this, now that IE6 is finally starting to die, I can use CSS attributes in selectors, so IMG[style="float: left;"] {} Works, but I would rather use a class incase there are any other style attributes which will cause the selector to fail. And it doesn't work in IE6, and you know some corporate clients will still be running the bloody thing! So I looked through the TinyMCE documentation and found the formats configuration option, that seems to allow you to specify how tinyMCE applies code for various operations. Here I can add the IMG tag as a selector, and have classes: "left" for the alignleft function. This applies the class correctly when the alignment is selected from the toolbar, but it still writes an inline style when the alignment is selected through the image dialogue. Am I doing something wrong or is there a better way of doing this that will allow my clients to select image alignment from both the image dialogue and the toolbar, whilst applying a class to the image?

  • JAVA - Create variable names using a loop?

    - by SeerUK
    Hi, first time poster, long time reader so be gentle with me :) See the following code which works to generate me timestamps for the beginning and end of every month in a financial year. int year = 2010; // Financial year runs from Sept-Aug so earlyMonths are those where year = FY-1 and lateMonths are those where year = FY int[] earlyMonths = {8, 9, 10, 11}; // Sept to Dec int earlyYear = year -1; for (int i : earlyMonths) { month = i; Calendar cal = Calendar.getInstance(); cal.clear(); cal.set(earlyYear,month,1,0,0,0); Long start = cal.getTimeInMillis(); cal.clear(); cal.set(earlyYear,month,1); lastDayofMonth = cal.getActualMaximum(GregorianCalendar.DAY_OF_MONTH); cal.set(earlyYear,month,lastDayofMonth,23,59,59); Long end = cal.getTimeInMillis(); } int[] lateMonths = {0, 1, 2, 3, 4, 5, 6, 7}; // Jan to Aug for (int i : lateMonths) { month = i; Calendar cal = Calendar.getInstance(); cal.clear(); cal.set(year,month,1,0,0,0); Long start = cal.getTimeInMillis(); cal.clear(); cal.set(year,month,1); lastDayofMonth = cal.getActualMaximum(GregorianCalendar.DAY_OF_MONTH); cal.set(year,month,lastDayofMonth,23,59,59); Long end = cal.getTimeInMillis(); } So far so good, but in order to use these results I need these timestamps to be output to variables named by month (to be used in a prepared statement later in the code. e.g. SeptStart = sometimestamp, SeptEnd = some timestamp etc etc. I don't know if it is possible to declare new variables based on the results of each loop. Any ideas?

  • WCF Custom Delegation/Authentication without Kerberos

    - by MichaelGG
    I'm building a simple WCF service, probably exposed via HTTPS, using NTLM security. Since not all users are going to be capable of using the service directly, we're writing a simple web front-end for the service. Users will auth with HTML to the web front-end. What we want is a way to delegate the user of the web site all the way to the WCF service. I understand Kerberos delegation can do this, but that's not available to us. What I want to do is make the web front-end account a specially trusted account, so that if a request hits the WCF service authenticated as "DOMAIN\WebApp", we read a WCF message header containing the real identity, then switch the principal to that and continue as normal. Is there any "simple" way of achieving this? Should I give up entirely on this idea, and instead make users "sign-in" to the WCF app and then do complete custom auth? The WCF extensibility and security options seem so vast, I'd like to get a heads up on which path to start heading down.

  • SL 3 navigation not working!

    - by Silver Gun
    Hey Guys I converted all my existing Silverlight app UserControls to Pages so I could use the Navigation Framework. Anyway so I created a UserControl called MyFrame, which would host all the pages. In my App.xaml.cs I have the following to make sure that MyFrame is loaded when the App loads: private void Application_Startup(object sender, StartupEventArgs e) { this.RootVisual = new MyFrame(); } My UriMapper class resides in App.xaml and looks like the following: <navcore:UriMapper x:Key="uriMapper"> <navcore:UriMapping Uri="Login" MappedUri="Login.xaml"> </navcore:UriMapper> Within my 'MyFrame' class, I have the following <StackPanel Orientation="Horizontal"> <StackPanel Orientation="Vertical"> <HyperlinkButton Tag="Login" Content="Login" Click="HyperlinkButton_Click" /> </StackPanel> <StackPanel Orientation="Vertical"> <navigation:Frame x:Name="ContentFrame" Style="{StaticResource ContentFrameStyle}" /> </StackPanel> </StackPanel> And within the callback for my HyperlinkButton's event handler, I have the following: private void HyperlinkButton_Click(object sender, RoutedEventArgs e) { ContentFrame.Navigate(new Uri((sender as HyperlinkButton).Tag.ToString(), UriKind.Relative)); } The Login.xaml file is in my root folder (right under Project). This navigation does not seem to work! The exception I get reads like so: Navigation is only supported to relative URIs that are fragments, or begin with '/', or which contain ';component/'. Parameter name: uri The Login page does not load. There is no problem with Login.xaml as when I set this.RootVisual = new Login(); the page loads just fine. I also tried setting the NavigateUri attribute of the HyperlinkButton to "Login." No cigar. I'll appreciate any help! Thanks a lot in advance

  • How can I work around "Xcode could not locate source file"

    - by Septih
    Hello, I'm working with the ID3 framework in Xcode (which has since disappeared off the face of the web - including google cache!). I'm testing out an import mp3 feature which allows them to edit the tags as they import them. One of the test cases is a corrupt or invalid mp3 with no proper id3 header. The problem I'm having is that when updating the tags of the invalid mp3 (updateFile:), the ID3 framework attempts to use id3V1Tag.m (I assume it falls back to this if it can't find the v2 tag) and this is where I get the Xcode error (whilst running the program, not building): Xcode could not locate source file: id3V1Tag.m (line: 299) Even in a release build this crashes the program, so it's not something I can really ignore. I've tried putting a try/catch block around it but it's not treated as an exception so doesn't get caught. The function to load the tag data for the file returns a BOOL but it appears this only returns false if the given file doesn't exist, so this doesn't help either. Current code: [tagData release]; tagData = [[TagAPI alloc] initWithGenreList:nil]; tagsLoaded = [tagData examineFile:exportPath]; if(tagsLoaded) { [tagData setTitle:title]; [tagData setArtist:artist]; [tagData setComments:comments]; @try { [tagData updateFile]; } @catch (id e){ NSLog(@"h"); } }

  • Form is submitting when the page loads

    - by RailAddict
    I have a really simple Rails app. Basically an article with comments. I want the article page to show the article, comments underneath and then a textbox to write a comment and a submit button to submit it. I got it all working except for one (big) problem. When the page loads.. example.com/article/1 a blank comment is submitted to the database. I fixed that by including "validates_presence_of :body" in the Comment model. But that results in the following image when the page loads: This is my code by the way: def show @place = Article.find(params[:id]) @comment = Article.find(params[:id]).comments.create(params[:comment]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @article } end end and <% form_for([@article, @comment]) do |f| %> <p> <%= f.label :commenter %><br /> <%= f.text_field :commenter %> </p> <p> <%= f.label :body %><br /> <%= f.text_area :body %> </p> <p> <%= f.submit "Create" %> </p> <% end %>

  • how to fix: ctags null expansion of name pattern "\1"

    - by bua
    Hi, As the title points I have problem with ctags when trying to parse user-defined language. Basically I've followed those instructions. The quickest and easiest way to do this is by defining a new language using the program options. In order to have Swine support available every time I start ctags, I will place the following lines into the file $HOME/.ctags, which is read in every time ctags starts: --langdef=swine --langmap=swine:.swn --regex-swine=/^def[ \t]*([a-zA-Z0-9_]+)/\1/d,definition/ The first line defines the new language, the second maps a file extension to it, and the third defines a regular expression to identify a language definition and generate a tag file entry for it. I've tried different flags: b,e for regex. My definition of tag is: --regex-q=/^[ \t]*[^[:space:]]*[:space:]*:[:space:]*{/\l/f,function/b When I replace \1 with anything else (ascii caracter set ), It works. the output is: (--regex-q=/^[ \t]*[^[:space:]]*[:space:]*:[:space:]*{/my function name/f,function/b) !_TAG_FILE_FORMAT 2 /extended format; --format=1 will not append ;" to lines/ !_TAG_FILE_SORTED 1 /0=unsorted, 1=sorted, 2=foldcase/ !_TAG_PROGRAM_AUTHOR Darren Hiebert /[email protected]/ !_TAG_PROGRAM_NAME Exuberant Ctags // !_TAG_PROGRAM_URL http://ctags.sourceforge.net /official site/ !_TAG_PROGRAM_VERSION 5.8 // my function name file.q /^.ras.getLocation:{[u]$/;" f my function name file.q /^.a.getResource:{[u; pass]$/;" f my function name file.q /^.a.init:{$/;" f my function name file.q /^.a.kill:{[u; force]$/;" f my function name file.q /^.asdf.status:{[what; u]$/;" f my function name file.q /^.pc:{$/;" f Why \1 doesn't work? (I've tried all 1-9)

  • Sharing large objects between ruby processes without a performance hit

    - by Gdeglin
    I have a Ruby hash that reaches approximately 10 megabytes if written to a file using Marshal.dump. After gzip compression it is approximately 500 kilobytes. Iterating through and altering this hash is very fast in ruby (fractions of a millisecond). Even copying it is extremely fast. The problem is that I need to share the data in this hash between Ruby on Rails processes. In order to do this using the Rails cache (file_store or memcached) I need to Marshal.dump the file first, however this incurs a 1000 millisecond delay when serializing the file and a 400 millisecond delay when serializing it. Ideally I would want to be able to save and load this hash from each process in under 100 milliseconds. One idea is to spawn a new Ruby process to hold this hash that provides an API to the other processes to modify or process the data within it, but I want to avoid doing this unless I'm certain that there are no other ways to share this object quickly. Is there a way I can more directly share this hash between processes without needing to serialize or deserialize it? Here is the code I'm using to generate a hash similar to the one I'm working with: @a = [] 0.upto(500) do |r| @a[r] = [] 0.upto(10_000) do |c| if rand(10) == 0 @a[r][c] = 1 # 10% chance of being 1 else @a[r][c] = 0 end end end @c = Marshal.dump(@a) # 1000 milliseconds Marshal.load(@c) # 400 milliseconds

  • Shared Server Dreamhost

    - by Jseb
    I am trying to install an app on a shared server. If i understand properly because i am using a shared server, and that Dreamhost doesn't suppose rails 3.2.8 I must use FCGI, although i am not sure how to install and to make it run properly. From this tutorial http://wiki.dreamhost.com/Rails_3. To my understand here what I did, In dreamhost, activate PHP 5.x.x FastCGI and made sure Phusion Passenger is unchecked Create an app on my localmachine Because rails doesn't create a dispatch and access file i create the two following file in my /public folder dispatch.fcgi #!/home/username/.rvm/rubies/ruby-1.9.3-p327/bin/ruby ENV['RAILS_ENV'] ||= 'production' ENV['HOME'] ||= `echo ~`.strip ENV['GEM_HOME'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327') ENV['GEM_PATH'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327') + ":" + File.expand_path('~/.rvm/gems/ruby 1.9.3-p327@global') require 'fcgi' require File.join(File.dirname(__FILE__), '../config/environment') class Rack::PathInfoRewriter def initialize(app) @app = app end def call(env) env.delete('SCRIPT_NAME') parts = env['REQUEST_URI'].split('?') env['PATH_INFO'] = parts[0] env['QUERY_STRING'] = parts[1].to_s @app.call(env) end end Then created the file .htaccess <IfModule mod_fastcgi.c> AddHandler fastcgi-script .fcgi </IfModule> <IfModule mod_fcgid.c> AddHandler fcgid-script .fcgi </IfModule> Options +FollowSymLinks +ExecCGI RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ dispatch.fcgi/$1 [QSA,L] ErrorDocument 500 "Rails application failed to start properly" Uploaded to a folder and pointed to the public folder in dreamhost Made sure dispatch.fcgi has 777 for write ssh and run the following command in the public folder : ./dispatch.fcgi Crossing my finger but it doesn't work I get the following errors ./dispatch.fcgi: line 1: ENV[RAILS_ENV]: command not found ./dispatch.fcgi: line 1: =: command not found ./dispatch.fcgi: line 2: ENV[HOME]: command not found ./dispatch.fcgi: line 2: =: command not found ./dispatch.fcgi: line 3: syntax error near unexpected token (' ./dispatch.fcgi: line 3:ENV['GEM_HOME'] = File.expand_path('~/.rvm/gems/ruby 1.9.3-p327')' Doing wrong???

  • acts_as_solr isn't updating associated models in Rails

    - by Trey Bean
    I'm using acts_as_solr for searching in a project. Unfortunately, the index doesn't seem to be updated for the associated models when a model is saved. Example: I have three models: class Merchant < ActiveRecord::Base acts_as_solr :fields => [:name, :domain, :description], :include => [:coupons, :tags] ... end class Coupon < ActiveRecord::Base acts_as_solr :fields => [:store_name, :url, :code, :description] ... end class Tag < ActiveRecord::Base acts_as_solr :fields => [:name] ... end I use the following line to perform a search: Merchant.paginate_by_solr(params[:q], :per_page => PER_PAGE, :page => [(params[:page] || 1).to_i, 1].max) For some reason though, after I add a coupon that contains the word 'shoes' in the description, a query for 'shoes' doesn't return the merchant associated with the coupon. The association all work and if I run rake solr:reindex, the search then returns the new coupon. Do I need to update the index for Merchant each time a new coupon is created? Do I have to update the index for the whole class or can I just update the associated merchant? Shouldn't this be done automatically? Thanks for any input.
