  • Help me with query string parameters (Rails)

    - by Martin Petrov
    Hi, I'm creating a newsletter. Each email contains a link for editing your subscription: <%= edit_user_url(@user, :secret => @user.created_at.to_i) %> :secret = @user.created_at.to_i prevents users from editing each others profiles. def edit @user = user.find(params[:id]) if params[:secret] == @user.created_at.to_i render 'edit' else redirect_to root_path end end It doesn't work - you're always redirected to root_path. It works if I modify it like this: def edit @user = user.find(params[:id]) if params[:secret] == "1293894219" ... 1293894219 is the "created_at.to_i" for a particular user. Do you have any ideas why?

  • How does ruby allow a method and a Class with the same name?

    - by Daniel Beardsley
    I happened to be working on a Singleton class in ruby and just remembered the way it works in factory_girl. They worked it out so you can use both the long way Factory.create(...) and the short way Factory(...) I thought about it and was curious to see how they made the class Factory also behave like a method. They simply used Factory twice like so: def Factory (args) ... end class Factory ... end My Question is: How does ruby accomplish this? and Is there danger in using this seemingly quirky pattern?

  • Implementing an iterator over binary tree using C++ 11

    - by user1459339
    I would like to create an iterator over the binary tree so as to be able to use range-based for loop. I understand I ought to implement the begin() and end() function first. Begin should probably point to the root. According to the specification, however, the end() functions returns "the element following the last valid element". Which element (node) is that? Would it not be illegal to point to some "invalid" place? The other thing is the operator++. What is the best way to return "next" element in tree? I just need some advice to begin with this programming.

  • Access Ruby on Rails 'public' directory without relative path

    - by huntca
    I have a flash object I wish to load and I belive the best place to store that asset is in the public directory. Suppose it's stored in public/flash, there must be a better way to path to the swf than what I've done below. Note the 'data' element, it has a relative path. def create_vnc_object haml_tag :object, :id => 'flash', :width => '100%', :height => '100%', :type => 'application/x-shockwave-flash', :data => '../../flash/flash.swf' do haml_tag :param, :name => 'movie', :value => '../../flash/flash.swf' end end Is there some rails variable that points to public?

  • Simplifying CASE WHEN SQL statement

    - by kateroh
    Im trying to improve the following CASE statement to calculate the difference only once. I do it to avoid negative numbers: SELECT (CASE WHEN ((SELECT 100 - (SELECT COUNT(CustomerId) FROM Customers)) > 0) THEN (SELECT 100 - (SELECT COUNT(CustomerId) FROM Customers)) ELSE (0) END) This not only looks stupid, but also is not thread-safe. I tried the following, but I get an error message "Invalid column name 'diff'." SELECT (CASE WHEN ((SELECT 100 - (SELECT COUNT(CustomerId) FROM Customers) as diff) > 0) THEN (diff) ELSE (0) END) How can this be simplified? Is there an in-built SQL function that already does this job? EDIT: Sorry, forgot to mention that the select statement is inside of a view declaration, so I cant declare variables.

  • Jquery load() loading more than I want...

    - by Probocop
    Hi, I am trying to load just the contents of a <div> into another <div> on the same page using a jquery function. But when the function triggers, it loads the entire <HTML> document into the specified <div>. Any idea why it would be doing this? My code is as follows: Jquery: function button1() { $('#sidebar-content').fadeOut(function() { $(this).load('#button1').fadeIn(); }); } function button2() { $('#sidebar-content').fadeOut(function() { $(this).load('#button2').fadeIn(); }); } HTML: <div id="content-holder"> <div id="main-content" class="float-holder"> <div id="inner"> <h1>BRAND TRUTH</h1> <div id="flashcontent"> <div id="button1"> <div id="content"> <h1>Brand Truth</h1> <p>What this basically means is our way of working, the process involved by both ourselves and our client.</p> <p>When the truth wheel process is followed, the end result is so much stronger.</p> </div> </div> <div id="button2"> <div id="content"> <h1>Button 2 Content</h1> <p>Some other content</p> <p>Some other content x2</p> </div> </div> </div> <script type="text/javascript"> // <![CDATA[ var so = new SWFObject("working.swf", "working", "400", "400", "9", "#FFFFFF"); so.write("flashcontent"); // ]]> </script> </div> <div id="sidebar"> <div id="sidebar-content"> Replace Content Here! </div> </div> </div><!-- end #main-content --> </div><!-- end #content-holder -->

  • Can set_intersection be used with hash_set in C++?

    - by R S
    I am calculating intersection, union and differences of sets. I have a typedef of my set type: typedef set<node_type> node_set; When it is replaced with typedef hash_set<node_type> node_set; The results are different. It's a complicated program, and before I start debugging - am I doing it right? When I use functions like this: set_intersection(v_higher.begin(), v_higher.end(), neighbors[w].begin(), neighbors[w].end(), insert_iterator<node_set>(tmp1, tmp1.begin())); should they work seamlessly with both set and hash_set?

  • Conditional Branching Issues

    - by Zack
    Here is the code: def main_menu print_main_menu user_selected = gets.chomp if user_selected.downcase == "no" main_menu elsif user_selected == "1" || "2" || "3" || "4" || "5" || "6" || "7" user_selected = user_selected.to_i call_option(user_selected) else main_menu end end This code uses calls to allow a user to make a selection from a main menu. Depending on the input, be it a certain number, a certain word, or something else, the respective method is called (in the case of a valid input) or the main menu is printed again (in the case of an invalid input or "no"). My questions are twofold. 1) Is there an efficient way to get rid of the literal string error that appears as a result of this redundant or statement on the elsif line? (the code itself works fine, but this error appears and is frustrating). 2) When an alternate/unspecified input is made by the user, the else branch doesn't execute and main_method doesn't start over. I have no idea why this is happening. Is there something I'm missing here? Thanks

  • functionality of cin in c++

    - by wyatt
    I'm a bit confused by the results of the following function: int main() { string command; while(1) { cin >> command; if(command == "end") return 0; else cout << "Could you repeat the command?" << endl; } return 0; } First of all - the output line ("could you...") repeats once for each individual word in the input (stored in command). So far as I can see, it should only be possible for it to happen once for each instance of the loop. Also, when the line 'if(command == "end")' is changed to 'if(command == "that's all")' it never triggers. A little testing suggested that all of the whitespace was removed from the command. Could someone explain to me what's going on here? Thanks

  • Outlook 2010 Populating a Text Box

    - by Turkwise
    all! I'll try to be as detailed as possible in describing my predicament. I have a little background knowledge in Visual Basic, but none really in VBA or VBscript in Outlook 2010. I'm working with Outlook 2010. I created a custom form (this is my first time). I have a combo box named ComboBox1 and a text box named TextBox1. I am trying to auto-populate TextBox1 with a number based on the selection made from ComboBox1 (ex. I select Value 1 from ComboBox1 and TextBox1 populates with 124). I made an attempt using this code in the Visual Basic Editor (VBA version 7.0): Sub popBox() If ComboBox1 = "Value 1" Then TextBox1 = "124" End If End Sub My question is what am I doing wrong? Should I be using the VBscript editor, or is using VBA the proper thing to do? Is what I am asking even possible? Thank you all in advance!
