  • My Lucene queries only ever find one hit

    - by Bob
    I'm getting started with Lucene.Net (stuck on version 2.3.1). I add sample documents with this: Dim indexWriter = New IndexWriter(indexDir, New Standard.StandardAnalyzer(), True) Dim doc = Document() doc.Add(New Field("Title", "foo", Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) doc.Add(New Field("Date", DateTime.UtcNow.ToString, Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) indexWriter.AddDocument(doc) indexWriter.Close() I search for documents matching "foo" with this: Dim searcher = New IndexSearcher(indexDir) Dim parser = New QueryParser("Title", New StandardAnalyzer()) Dim Query = parser.Parse("foo") Dim hits = searcher.Search(Query) Console.WriteLine("Number of hits = " + hits.Length.ToString) No matter how many times I run this, I only ever get one result. Any ideas?

  • Making a Login Work After Cache, Cookies, etc. Have Been Cleared

    - by John
    Hello, I am using the code below for a user login. The first I try to login after cache / cookies, etc. have been cleared, the browser refreshes and the user name is not logged in. After that, logging in works fine. Any idea how I can make it work the first time? Thanks in advance, John index.php: <?php if($_SERVER['REQUEST_METHOD'] == "POST"){header('Location: http://www...com/.../index.php?username='.$username.'&password='.$password.'');} require_once "header.php"; include "login.php"; require_once "footer.php"; ?> login.php: <?php if (!isLoggedIn()) { if (isset($_POST['cmdlogin'])) { if (checkLogin($_POST['username'], $_POST['password'])) { show_userbox(); } else { echo "Incorrect Login information !"; show_loginform(); } } else { show_loginform(); } } else { show_userbox(); } ?> show_loginform function: function show_loginform($disabled = false) { echo '<form name="login-form" id="login-form" method="post" action="./index.php?'.$_SERVER['QUERY_STRING'].'"> <div class="usernameformtext"><label title="Username">Username: </label></div> <div class="usernameformfield"><input tabindex="1" accesskey="u" name="username" type="text" maxlength="30" id="username" /></div> <div class="passwordformtext"><label title="Password">Password: </label></div> <div class="passwordformfield"><input tabindex="2" accesskey="p" name="password" type="password" maxlength="15" id="password" /></div> <div class="registertext"><a href="http://www...com/.../register.php" title="Register">Register</a></div> <div class="lostpasswordtext"><a href="http://www...com/.../lostpassword.php" title="Lost Password">Lost password?</a></div> <p class="loginbutton"><input tabindex="3" accesskey="l" type="submit" name="cmdlogin" value="Login" '; if ($disabled == true) { echo 'disabled="disabled"'; } echo ' /></p></form>'; }

  • word ladder in python

    - by user365523
    I'm trying to create a word ladder program in python. I'd like to generate words that are similar to a given word. In c++ or java, I would go through each valid index in the original string, and replace it with each letter in the english alphabet, and see if the result is a valid word. for example (pseudocode) for (int i = 0; i < word.length(); i++) { for (every character c in the alphabet) { change the letter of word at index i to be c. if the result is a valid word, store it in a list of similar words } } . However, this doesn't seem like a very "python" way of doing things. How would I approach this problem in python?

  • Should I use integer primary IDs?

    - by arthurprs
    For example, I always generate an auto-increment field for the users table, but I also specify a UNIQUE index on their usernames. There are situations that I first need to get the userId for a given username and then execute the desired query, or use a JOIN in the desired query. It's 2 trips to the database or a JOIN vs. a varchar index. Should I use integer primary IDs? Is there a real performance benefit on INT over small VARCHAR indexes?

  • is this a secure approach in ActiveRecords in Rails?

    - by Adnan
    Hello, I am using the following for my customers to unsubscribe from my mailing list; def index @user = User.find_by_salt(params[:subscribe_code]) if @user.nil? flash[:notice] = "the link is not valid...." render :action => 'index' else Notification.delete_all(:user_id => @user.id) flash[:notice] = "you have been unsubscribed....." redirect_to :controller => 'home' end end my link looks like; http://site.com/unsubscribe/32hj5h2j33j3h333 so the above compares the random string to a field in my user table and accordingly deletes data from the notification table. My question; is this approach secure? is there a better/more efficient way for doing this? All suggestions are welcome.

  • Searching in Ruby on Rails - How do I search on each word entered and not the exact string?

    - by bgadoci
    I have built a blog application w/ ruby on rails and I am trying to implement a search feature. The blog application allows for users to tag posts. The tags are created in their own table and belong_to :post. When a tag is created, so is a record in the tag table where the name of the tag is tag_name and associated by post_id. Tags are strings. I am trying to allow a user to search for any word tag_name in any order. Here is what I mean. Lets say a particular post has a tag that is 'ruby code controller'. In my current search feature, that tag will be found if the user searches for 'ruby', 'ruby code', or 'ruby code controller'. It will not be found if the user types in 'ruby controller'. Essentially what I am saying is that I would like each word entered in the search to be searched for, not necessarily the 'string' that is entered into the search. I have been experimenting with providing multiple textfields to allow the user to type in multiple words, and also have been playing around with the code below, but can't seem to accomplish the above. I am new to ruby and rails so sorry if this is an obvious question and prior to installing a gem or plugin I thought I would check to see if there was a simple fix. Here is my code: View: /views/tags/index.html.erb <% form_tag tags_path, :method => 'get' do %> <p> <%= text_field_tag :search, params[:search], :class => "textfield-search" %> <%= submit_tag "Search", :name => nil, :class => "search-button" %> </p> <% end %> TagsController def index @tags = Tag.search(params[:search]).paginate :page => params[:page], :per_page => 5 @tagsearch = Tag.search(params[:search]) @tag_counts = Tag.count(:group => :tag_name, :order => 'count_all DESC', :limit => 100) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @tags } end end Tag Model class Tag < ActiveRecord::Base belongs_to :post validates_length_of :tag_name, :maximum=>42 validates_presence_of :tag_name def self.search(search) if search find(:all, :order => "created_at DESC", :conditions => ['tag_name LIKE ?', "%#{search}%"]) else find(:all, :order => "created_at DESC") end end end

  • 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.

  • PyParsing: Is this correct use of setParseAction()?

    - by Rosarch
    I have strings like this: "MSE 2110, 3030, 4102" I would like to output: [("MSE", 2110), ("MSE", 3030), ("MSE", 4102)] This is my way of going about it, although I haven't quite gotten it yet: def makeCourseList(str, location, tokens): print "before: %s" % tokens for index, course_number in enumerate(tokens[1:]): tokens[index + 1] = (tokens[0][0], course_number) print "after: %s" % tokens course = Group(DEPT_CODE + COURSE_NUMBER) # .setResultsName("Course") course_data = (course + ZeroOrMore(Suppress(',') + COURSE_NUMBER)).setParseAction(makeCourseList) This outputs: >>> course.parseString("CS 2110") ([(['CS', 2110], {})], {}) >>> course_data.parseString("CS 2110, 4301, 2123, 1110") before: [['CS', 2110], 4301, 2123, 1110] after: [['CS', 2110], ('CS', 4301), ('CS', 2123), ('CS', 1110)] ([(['CS', 2110], {}), ('CS', 4301), ('CS', 2123), ('CS', 1110)], {}) Is this the right way to do it, or am I totally off? Also, the output of isn't quite correct - I want course_data to emit a list of course symbols that are in the same format as each other. Right now, the first course is different from the others. (It has a {}, whereas the others don't.)

  • Changing the size of the UISearchBar TextField ?

    - by Padraig
    I have a UITableView with an Index on the side; I want to add a UISearchBar to it, but the index overlaps with the "x" to clear the search. I've noticed in the Contacts application, the textfield within the UISearchBar is resized to accommodate this, but I can't work out how to do this in my own app. I have tried the following in my viewDidLoad, but it does not seem to work. UITextField * textField = (UITextField *)[[self.search subviews] objectAtIndex:0]; CGRect r = textField.frame; [textField setFrame:CGRectMake(r.origin.x, r.origin.y, r.size.height, r.size.width-30)]; Any ideas?

  • How to implement User routing like that in StackOverflow ?

    - by rockinthesixstring
    I've looked at the routing on StackOverflow and I've got a very noobie question, but something I'd like clarification none the less. I'm looking specifically at the Users controller http://stackoverflow.com/Users http://stackoverflow.com/Users/Login http://stackoverflow.com/Users/124069/rockinthesixstring What I'm noticing is that there is a "Users" controller probably with a default "Index" action, and a "Login" action. The problem I am facing is that the login action can be ignored and a "UrlParameter.Optional [ID]" can also be used. How exactly does this look in the RegisterRoutes collection? Or am I missing something totally obvious? EDIT: Here's the route I have currently.. but it's definitely far from right. routes.MapRoute( _ "Default", _ "{controller}/{id}/{slug}", _ New With {.controller = "Events", .action = "Index", .id = UrlParameter.Optional, .slug = UrlParameter.Optional} _ )

  • Wordpress Custom Themes > How to script Categories, Tags and Excerpt options to appear on "page" edi

    - by Scott B
    I'm using custom WordPress categories for some probably unintended functions, I will admit (things like marking a post no/index just by adding it to my custom "no-index" category, etc). But it sucks that WordPress does not enable pages with all the little extras you get with posts. For example, while the post editor gives you convenient access to Tags, Categories, and a Post excerpt field, pages get left out in the cold. I'd like to know if its possible to add the These items to the Post editor via add_action() directive from a custom theme.

  • .htaccess newb - RewriteRule not matching 2nd rule, why?

    - by jyoseph
    I am currently migrating from isapi_rewrite to .htaccess. I'm having some difficulty and I think it's something basic, but I'm not terribly familiar with .htaccess. I have the two rules like so: RewriteRule ^testing/ /test/index.html?test=1 [NC] RewriteRule ^testing/foo-bar/ /test/index.html?test=2 [NC] Yet the second rule never matches. If I go to http://mydomain.com/testing/foo-bar/ then I will only see the first rule. Why is that? And can it be easily fixed? I have many rules (outputted from the database to write the .htaccess file )and ordering them in a particular order isn't really possible.

  • div popup inside td

    - by sims
    I have a table with a bunch of cells. (No way! Amazing! :P) Some of the cells have a small div that when you put your mouse over, it gets bigger so you can read all the text. This works well and all. However, since html elements that come later in the document have a higher z-index, when the div gets bigger it is underneath the other divs in the other cells. Some html code: <table> <tr> <td> limited info <div style="position: relative;"> <div style="position: absolute; top: 0; left: 0; width: 1em; height: 1em;" onmouseover="tooltipshow(this)" onmouseout="tooltiphide(this)"> informative long text is here </div> </div> </td> <td> some short info <div style="position: relative;"> <div style="position: absolute; top: 0; left: 0; width: 1em; height: 1em;" onmouseover="tooltipshow(this)" onmouseout="tooltiphide(this)"> longer explanation about what is really going on that covers the div up there ^^^. darn! </div> </div> </td> </tr> </table> Some js code: function tooltipshow(obj) { obj.style.width = '30em'; obj.style.zIndex = '100'; } function tooltiphide(obj) { obj.style.width = '1em'; obj.style.zIndex = '20'; } It doesn't matter if I set z-index dynamically to something higher onmouseover. It's like z-index has no affect. I think it has something to do with the table. I've tested this in FF3. When I'm feeling particularly macho, I'll test it in IE.

  • Highlight polygon and tint rest of map using Google Maps

    - by Haes
    Hi, I'd like to display a highlighted polygon using Google Maps. The idea is that the polygon in question would be displayed normally and the rest of the map should be darkened a little bit. Here's an example image what I would like to accomplish with a polygon from Austria: Unfortunately, I'm a complete rookie when it comes to Google Maps API's and map stuff in general. So, is this even possible do this with Google Map API's? If yes, with what version (v2, v3)? Would it be easier to do it with other map toolkits, like openlayers? PS: One idea I had, was to build an inverse polygon (in this example, the whole world minus the shape of austria) and then display a black colored overlay with transparency using this inverted polygon. But that seems to be quite complicated to me.

  • Devise and cancan gems: has_many association

    I use devise and cancan gems and have simple model association: user has_many subscriptions, subscription belongs_to :user. Have following SubscriptionsController: class SubscriptionsController < ApplicationController load_and_authorize_resource :user load_and_authorize_resource :subscription, through: :user before_filter :authenticate_user! def index @subscriptions = @user.subscriptions.paginate(:page => params[:page]).order(:created_at) end #other actions end And Cancan Ability.rb: class Ability include CanCan::Ability def initialize(user) user ||=User.new can [:index, :show], [Edition, Kind] if user.admin? can :manage, :all elsif user.id can [:read, :create, :destroy, :pay], Subscription, user_id: user.id can [:delete_from_cart, :add_to_cart, :cart], User, id: user.id end end end The problem is that i cannot use subscriptions actions as a user but can as a admin. And have no problems with UsersController. When i delete following lines from SubscriptionsController: load_and_authorize_resource :user load_and_authorize_resource :subscription, through: :user before_filter :authenticate_user!

  • Longest substring that appears n times

    - by xcoders
    For a string of length L, I want to find the longest substring that appears n (n<L) or more times in ths string. For example, the longest substring that occurs 2 or more times in "BANANA" is "ANA", once starting from index 1, and once again starting from index 3. The substrings are allowed to overlap. In the string "FFFFFF", the longest string that appears 3 or more times is "FFFF". The brute force algorithm for n=2 would be selecting all pairs of indexes in the string, then running along until the characters are different. The running-along part takes O(L) and the number of pairs is O(L^2) (duplicates are not allowed but I'm ignoring that) so the complexity of this algorithm for n=2 would be O(L^3). For greater values of n, this grows exponentially. Is there a more efficient algorithm for this problem?

  • Error using MVCContrib TestHelper

    - by Brian McCord
    While trying to implement the second answer to a previous question, I am receiving an error. I have implemented the methods just as the post shows, and the first three work properly. The fourth one (HomeController_Delete_Action_Handler_Should_Redirect_If_Model_Successfully_Delete) gives this error: Could not find a parameter named 'controller' in the result's Values collection. If I change the code to: actual .AssertActionRedirect() .ToAction("Index"); it works properly, but I don't like the "magic string" in there and prefer to use the lambda method that the other poster used. My controller method looks like this: [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What am I doing wrong?

  • slashes in url variables

    - by namtax
    Hi there I have set up my coldfusion application to have dynamic urls on the page, such as www.musicExplained/index.cfm/artist/:VariableName However my variable names will sometimes contain slashes, such as www.musicExplained/index.cfm/artist/GZA/Genius This is causing a problem, because my application presumes that the slash in the variable name represents a different section of the website, the artists albums. So the URL will fail. I am wondering if there is anyway to prevent this from happening? Do I need to use a function that replaces slashes in the variable names with another character? Thanks

  • How to parse a Zend URL for parameters?

    - by wizzard
    I am trying to extract the GET parameters from a ZF REST URL. It's not the current request and I don't want to call the URL or execute the route, I just need the parameters. I'm looking for a utility function like parse_url(), but for the Zend REST format. Is there one, or do I have to reinvent the wheel? I've tried a few things like creating a new Zend_Controller_Request_Http but the parameters aren't being populated. It is a valid HTTP URL. Edit: Upon request, a sample Zend URL: http://localhost/index/index/param1/foo/param2/bar So I am just trying to get param1 and param2 out of this URL.
