  • MongoMapper: how do I create a model like this

    - by Vladimir R
    Suppose we have two models, Task and User. So a user can have many tasks and tasks should be able to have many users too. But, a task should also have a unique creator who is also a user. Exemple: A task in this context is like this: Task ID, Task Creator, Users who should do the task User_1 creates a task and he is then the creator. User_1 specifies User_2 and User_3 as users who should do the task. So these two last users are not creators of task. How do I create this models so that if I have a task object, I can find it's creator and users who should complete it. And how do I do, if I have a user, to find all tasks he created and all tasks he should complete. Thank you.

  • How do I design this link table?

    - by Soo
    Ok SO, I have a user table and want to define groups of users together. The best solution I have for this is to create three database tables as follows: UserTable user_id user_name UserGroupLink group_id member_id GroupInfo group_id group_name This method keeps the member and group information separate. This is just my way of thinking. Is there a better way to do this? Also, what is a good naming convention for tables that link two other tables?

  • Showing div based on filled form field

    - by Fabio
    I have this script where I use a slider to show some elements of a form. So far so good. The way I'm doing it is by having a slider (can't use a multistep form since it uses a plugin not allowing multistep forms, plus some graphic behaviors) and a button that goes to the next slider. So now I need that button (not part of the form) to show only if a certain field is filled. I tried teh following, but it's not working, I assume some error but can't figure what. My code is as follows: $('#clientname').change(function() { var clientVal = $("input").val() == ''; $(".next").hide(); if ($('#clientname').val() != '').show(); else $('.next').hide(); }); and the html as follows: <div class="b40-right"> <h3>The Basics</h3> <div class="label"> Your Name (required)</div> <div class="inputes"> <span class="wpcf7-form-control-wrap your-name"><input id="clientname" type="text" name="your-name" value="" class="wpcf7-form-control wpcf7-text wpcf7-validates-as-required" size="40" /></span> </div> <div class="label">Your Email (required)</div> <div class="inputes"> <span class="wpcf7-form-control-wrap your-email"><input type="text" name="your-email" value="" class="wpcf7-form-control wpcf7-text wpcf7-email wpcf7-validates-as-required wpcf7-validates-as-email" size="40" /></span> </div> <div class="label">Type of Business</div> <div class="inputes"> <span class="wpcf7-form-control-wrap type-of-business"><textarea name="type-of-business" class="wpcf7-form-control wpcf7-textarea" cols="40" rows="10"></textarea></span> </div> </div> <a class="next" href="javascript:stepcarousel.stepBy('mygallery2', 1)"><img id="nextbut1" src="<?php bloginfo('template_directory'); ?>/images/next.png" alt="" /></a> any help on what am I doing wrong? Is there a better approach/solution? (I'm not a programmer as you may figure) Thank you in advance!

  • Limit checkboxes with jquery based on checked radio buttons

    - by Hiskie
    So, i have this problem with some checkboxes. First of all let me tell you about the "project" itself. It's a webform, the user must complete it and check some checkboxes and radio buttons depending on what he would like to purchase. First of them are 2 radio bullets, numbered 1 and 2, and represent the quantity of the product he wants to purchase. Next to those are about 5 checkboxes that represent the color of the product, it doesn't matter how many of them are, the thing is ... i want, when a user selects 1 at the radio buttons, only 1 checkbox to be active, if he selects 2 then only 2 checkboxes to be available to check. So.. could someone help me? I thought of jQuery but i don't know... There are two divs, the first div with the id of let's say #radioButtons has 2 radio buttons, and the second div has the rest of the checkboxes.

  • How to prepare a codebase for compiling on both Windows and Unix-based systems

    - by Max
    Hi! I am wondering about different solutions to easily compile my cross-platform application for both windows and unix. Right now I am using a makefile on Ubuntu, but before my codebase grows larger I'd like to perform the steps necessary to compile it on Windows, and then continue doing so regularly to see that it still works. I'd preferably not contaminate my SVN codebase repository with multiple "makefile" solutions, such as VC++ solutions and so on, I'd like a more automatic way. I tried using mingw with make for windows, but it seems my secondexpansion awesomeness doesn't work on the Windows version (or something like that). It wouldn't compile, and also complained about _winNT or something like that not being defined. How should I prepare my codebase for cross-platform easy compiling? Things like buildtools, perhaps autogenerate VS file from makefile, or something similar. Some preprocessor magic in a stdinc file perhaps? Thanks!

  • Change Rectangle Fill Based on ColumnWidth of a grid

    - by Coesy
    Essentially i want to do as the title says, if the columnwidth is .50 then the rectangle should be red, if it's .75 then it should be amber, and if it's 1 then it should be green. I thought I could achieve this with DataTriggers but for some reason I am getting "Object Reference Not Set To An Instance Of An Object" error, here is my code, am I missing something here? FYI the width property will be changed in the backend through a timer_tick event. <Grid x:Name="Grid1" Width="300" Height="30"> <Grid.ColumnDefinitions> <ColumnDefinition x:Name="MyColumn1" Width=".50*"></ColumnDefinition> <ColumnDefinition x:Name="MyColumn2" Width=".50*"></ColumnDefinition> </Grid.ColumnDefinitions> <Grid.Triggers> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value=".50*"> <Setter TargetName="rect" Property="Fill" Value="Red"></Setter> </DataTrigger> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value=".75*"> <Setter TargetName="rect" Property="Fill" Value="Yellow"></Setter> </DataTrigger> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value="1"> <Setter TargetName="rect" Property="Fill" Value="Green"></Setter> </DataTrigger> </Grid.Triggers> <Rectangle x:Name="rect" Grid.Column="0" HorizontalAlignment="Stretch"></Rectangle> <Rectangle Grid.Column="1" Fill="Blue"></Rectangle> </Grid>

  • php and mysql site design question

    - by Jacksta
    I am trying to build a website with mysql and php. This is the first site I have attempted so I want to write a little plan and get some feedback. The site allows users to add some text in a text field as a “comment”. Once the comment has been entered into the site it is added to the database where it can be voted for by other users. When a new comment has been added to the database it needs to create a new page, e.g. www.xxxxx.com/commentname or www.xxxxxx.com/?id=99981. There will be a list of "Comments" in the database along with the number of votes for each comment. The home page will have two functions. 1) Allow users to add a "comment" 2) Display two tables, each with 20 rows containing most "popular comments" and "recent comments" Each comment will generate its one page where the comment will be displayed. Here users can read the comment and Vote for the comment if they wish. Please help me out by explaining how to do the following. -Generate a new page whenever a comment is added to the database -Add a vote to the vote count in the comment database. -Display the top 20 most popular comments as per number of votes.

  • Java Stopping JApplet Components from Resizing based on Applet Size

    - by Doug
    Creating a JApplet I have 2 Text Fields, a button and a Text Area. private JPanel addressEntryPanel = new JPanel(new GridLayout(1,3)); private JPanel outputPanel = new JPanel(new GridLayout(1,1)); private JTextField serverTf = new JTextField(""); private JTextField pageTf = new JTextField(""); private JTextArea outputTa = new JTextArea(); private JButton connectBt = new JButton("Connect"); private JScrollPane outputSp = new JScrollPane(outputTa); public void init() { setSize(500,500); setLayout(new GridLayout(3,1)); add(addressEntryPanel); addressEntryPanel.add(serverTf); addressEntryPanel.add(pageTf); addressEntryPanel.add(connectBt); addressEntryPanel.setPreferredSize(new Dimension(50,50)); addressEntryPanel.setMaximumSize(addressEntryPanel.getPreferredSize()); addressEntryPanel.setMinimumSize(addressEntryPanel.getPreferredSize()); add(outputPanel); outputPanel.add(outputSp); outputTa.setLineWrap(true); connectBt.addActionListener(this); The problem is when debugging and putting it in a page the components / panels resize depending on the applet size. I don't want this. I want the textfields to be a certain size, and the text area to be a certain size. I've put stuff in there to set the size of them but they aren't working. How do I go about actually setting a strict size for either the components or the JPanel.

  • Preventing concurrent data modification in Web based app

    - by Manoj
    Hi, I am building a web app in Silverlight which allows users to view and edit a database. In order to prevent multiple users from editing the same data, I was thinking of implementing a lock and key mechanism, so that other users are made to wait when one particular user is editing the data. Is there any way in which we can have variable(flag specifying if a user is editing data) in the server which can be shared across multiple clients? Is there a better way to manage this type of conurrent data access issues?

  • Weird code appearing when I loop over model instances in Rails

    - by Tom Maxwell
    In my Rails app I'm trying to loop over the Submission instances inside my Folder instances with Rails templating code. It works. However, it's also returning each instance in code which doesn't seem to be JSON. It's what's returned when you look up an instance in the Rails console. Here's an example: #<Submission id: 112, title: nil, content: nil, created_at: "2013-10-10 23:29:39", updated_at: "2013-10-10 23:29:39", user_id: 1, folder_id: 1, parent_id: nil> Here's what the code looks like for the loop: <%= @folder.submissions.each do |x| %> <% if x.title != nil %> <div id="<%= x.id %>" class="submission-textual"> <h1><%= x.title %></h1> </div> <% else %> <% end %> <% end %> I checked my Folder and Submissions controllers but am not sure what this is. Why are these strings being rendered whenever I try and render an instance in my view? I'm still new to Ruby so that explains why I haven't seen this.

  • how to model a many to many relationship

    - by Maulin
    Here is the scenario, Articles have many Comments Users can write many Comments for many Articles The comments table contains both user_id article_id as foreign keys My models are set up like so class User < ActiveRecord::Base has_many :comments has_many :articles, :through => :comments class Article < ActiveRecord::Base has_many :comments has_many :users, :through => :comments class Comment < ActiveRecord::Base belongs_to :users belongs_to :articles My routes.rb has the following code map.resources :articles, :has_many => :comments map.resources :users, :has_many => :comments which produces the following routes new_article_comment edit_article_comment new_user_comment edit_user_comment etc... This is not what I want (atleast not what I think I want), since comments must always be related to users and article, how can I get a route like so new_user_article_comment edit_user_article_comment Then I could just do new_user_article_comment_path([@user, @article]) to create a new comment
