  • Rails routes and model woes

    - by Chris Maness
    I'm a little new to rails sorry if this seems basic Alright so here's the deal I'm creating an application that will have many users and all the users have many songs. However when I try to create a song I get the following error:No action responded to 1. Actions: create and new and my browser is at the url: http://0.0.0.0:3000/users/1/songs which is not the correct route it should have redirected to songs/create Here is my controller code: class SongsController < ApplicationController def index @user = current_user @songs = @user.songs end def new @user = current_user @song = @user.songs.build end def create @user = current_user @song = @user.songs.build(params[:song]) if @song.save redirect_to user_song_url(@user, @song) else render :action => "new" end end end If anyone can help I would greatly appreciate it.

  • Creating relationship between two model instances

    - by Lowgain
    This is probably pretty simple, but here: Say I've got two models, Thing and Tag class Thing < ActiveRecord::Base has_and_belongs_to_many :tags end class Tag < ActiveRecord::Base has_and_belongs_to_many :things end And I have an instance of each. I want to link them. Can I do something like: @thing = Thing.find(1) @tag = Tag.find(1) @thing.tags.add(@tag) If not, what is the best way to do this? Thanks!

  • Jquery Find an XML element based on the value of one of it's children

    - by NateD
    I'm working on a simple XML phonebook app to learn JQuery, and I can't figure out how to do something like this: When the user enters the first name of a contact in a textbox I want to find the entire record of that person. The XML looks like this: <phonebook> <person> <number> 555-5555</number> <first_name>Evelyn</first_name> <last_name>Remington</last_name> <address>Edge of the Abyss</address> <image>path/to/image</image> </person> <person> <number>+34 1 6444 333 2223230</number> <first_name>Max</first_name> <last_name>Muscle</last_name> <address>Mining Belt</address> <image>path/to/image</image> </person> </phonebook> and the best I've been able to do with the jQuery is something like this: var myXML; function searchXML(){ $.ajax({ type:"GET", url: "phonebook.xml", dataType: "xml", success: function(xml){myXML = $("xml").find("#firstNameBox").val())} }); } What I want it to do is return the entire <person> element so I can iterate through and display all that person's information. Any help would be appreciated.

  • Unsure how to design JavaScript / jQuery functionality which uses XML to create HTML objects

    - by Jack Roscoe
    Hi, I'm using JavScript and jQuery to read an XML document and subsequently use the information from the XML to create HTML objects. The main 'C' nodes in the XML document all have a type attribute, and depending on the type I want to run a function which will create a new html object using the other attributes assigned to that particular 'C' node node. Currently, I have a for loop which extracts each 'C' node from the XML and also it's attributes (e.g. width, height, x, y). Also inside the for loop, I have an if statement which checks the 'type' attribute of the current 'C' node being processed, and depending on the type it will run a different function which will then create a new HTML object with the attributes which have been drawn from the XML. The problem is that there may be more than one 'C' node of the same type, so for example when I'm creating the function that will run when a 'C' node of 'type=1' is detected, I cannot use the 'var p = document.createElement('p')' because if a 'C' node of the same type comes up later in the loop it will clash and override that element with that variable that has just been created. I'm not really sure how to approach this? Here is my entire script. If you need me to elaborate on any parts please ask, I'm sure it's not written in the nicest possible way: var arrayIds = new Array(); $(document).ready(function(){ $.ajax({ type: "GET", url: "question.xml", dataType: "xml", success: function(xml) { $(xml).find("C").each(function(){ arrayIds.push($(this).attr('ID')); }); var svgTag = document.createElement('SVG'); // Create question type objects function ctyp3(x,y,width,height,baC) { alert('test'); var r = document.createElement('rect'); r.x = x; r.y = y; r.width = width; r.height = height; r.fillcolor = baC; svgTag.appendChild(r); } // Extract question data from XML var questions = []; for (j=0; j<arrayIds.length; j++) { $(xml).find("C[ID='" + arrayIds[j] + "']").each(function(){ // pass values questions[j] = { typ: $(this).attr('typ'), width: $(this).find("I").attr('wid'), height: $(this).find("I").attr('hei'), x: $(this).find("I").attr('x'), y: $(this).find("I").attr('x'), baC: $(this).find("I").attr('baC'), boC: $(this).find("I").attr('boC'), boW: $(this).find("I").attr('boW') } alert($(this).attr('typ')); if ($(this).attr('typ') == '3') { ctyp3(x,y,width,height,baC); // alert('pass'); } else { // Add here // alert('fail'); } }); } } }); });

  • Can't destroy record in many-to-many relationship

    - by Dmart
    I'm new to Rails, so I'm sure I've made a simple mistake. I've set up a many-to-many relationship between two models: User and Group. They're connected through the junction model GroupMember. Here are my models (removed irrelevant stuff): class User < ActiveRecord::Base has_many :group_members has_many :groups, :through => :group_members end class GroupMember < ActiveRecord::Base belongs_to :group belongs_to :user end class Group < ActiveRecord::Base has_many :group_members has_many :users, :through => :group_members end The table for GroupMembers contains additional information about the relationship, so I didn't use has_and_belongs_to_many (as per the Rails "Active Record Associations" guide). The problem I'm having is that I can't destroy a GroupMember. Here's the output from rails console: irb(main):006:0> m = GroupMember.new => #<GroupMember group_id: nil, user_id: nil, active: nil, created_at: nil, updated_at: nil> irb(main):007:0> m.group_id =1 => 1 irb(main):008:0> m.user_id = 16 => 16 irb(main):009:0> m.save => true irb(main):010:0> m.destroy NoMethodError: undefined method `eq' for nil:NilClass from /usr/local/lib/ruby/gems/1.8/gems/activesupport-3.0.4/lib/active_support/whiny_nil.rb:48:in `method_missing' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/persistence.rb:79:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/locking/optimistic.rb:110:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/callbacks.rb:260:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activesupport-3.0.4/lib/active_support/callbacks.rb:413:in `_run_destroy_callbacks' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/callbacks.rb:260:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:235:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:292:in `with_transaction_returning_status' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/connection_adapters/abstract/database_statements.rb:139:in `transaction' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:207:in `transaction' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:290:in `with_transaction_returning_status' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:235:in `destroy' from (irb):10 This is driving me crazy, so any help would be greatly appreciated.

  • Change user control appearance based on state

I'm new to WPF and programming in general and I'm stuck on where to go from here. Any recommendations would be greatly appreciated!!

  • Set database based on how the application was started

    - by AaronThomson
    I have two Rails applications (lets call them APP-1 and APP-2), each of them has a dependancy on a third Rails application (APP-3). I would like to be able to run the tests for APP-1 and APP-2 in parallel on my CI server. The problem is, both need to start up APP-3 and write to a DB via the APP-3. This causes conflicts and failures if the tests are run in parallel. My idea for a solution is for APP-1 and APP-2 to each start their own instance of APP-3 and to have each instance point to a different DB. Is there a way to dynamically set the DB in the database.yml of APP-3 so that it connects to a different DB depending on which APP starts it up? FYI. APP-1 and APP-2 currently start APP-3 via rake tasks.

  • API-based solutions for sending payments to people without bank accounts

    - by Tauren
    I'm looking for inexpensive ways to send payments to hundreds or thousands of individual contractors, even if they do not have a bank account. Currently I only need to support payment in the USA, but may eventually be international. Here's the scenario: I offer a service that allows an organization or manager-type person to coordinate contractors for very short term jobs. These jobs are typically only an hour or two in length. A contractor may get only one job over an entire month, several jobs spread out over a month, multiple jobs on a single day, or any other combination. Thus, a single contractor could earn as little as one job's payment up to potentially payment for dozens. Payment for a month could be as little as $10 up to $1000's. Right now, the system provides payroll reports to the manager and it is the manager's responsibility to produce checks, stuff envelopes, and send mail via the US postal service. I'd like to remove this burden from the manager and have all the payments taken care of for them automatically by the system. I'm not sure where to start or what the best options would be. I'm starting to look into the following solutions, but don't know specifics yet and would like some advice before pursuing them. I'd also like to hear about other ideas or suggestions. PayPal (Send Money, Adaptive Payments, x.com, other???) Amazon (Flexible Payments System?) Fund some sort of pre-paid debit card? Web service with API that mails checks for you? Direct deposit via a bank API (for users with bank accounts)? The problem is that many of these contractors may not be able to obtain bank accounts or credit cards within the USA. I don't mind doing a hybrid of solutions, but are there any that would work well with this issue? I want the solution to be easy to use for the contractors, meaning that they can get the money easily (via check in the mail, debit card ATM withdrawal, etc.)

  • Partitioning data set in r based on multiple classes of observations

    - by Danny
    I'm trying to partition a data set that I have in R, 2/3 for training and 1/3 for testing. I have one classification variable, and seven numerical variables. Each observation is classified as either A, B, C, or D. For simplicity's sake, let's say that the classification variable, cl, is A for the first 100 observations, B for observations 101 to 200, C till 300, and D till 400. I'm trying to get a partition that has 2/3 of the observations for each of A, B, C, and D (as opposed to simply getting 2/3 of the observations for the entire data set since it will likely not have equal amounts of each classification). When I try to sample from a subset of the data, such as sample(subset(data, cl=='A')), the columns are reordered instead of the rows. To summarize, my goal is to have 67 random observations from each of A, B, C, and D as my training data, and store the remaining 33 observations for each of A, B, C, and D as testing data. I have found a very similar question to mine, but it did not factor in multiple variables. I feel silly asking this question because it seems so simple, but I'm stumped. Also, this is my first question on this site, so I apologize in advance for any faux pas on my part.

  • Java hashcode based on identity

    - by hjfreyer
    The default behavior of Object.hashCode() is to return essentially the "address" of the object so that a.hashCode() == b.hashCode() if and only if a == b. How can I get this behavior in a user-defined class if a superclass already defines hashCode()? For instance: class A { public int hashCode() { return 0; } } class B extends A { public int hashCode() { // Now I want to return a unique hashcode for each object. // In pythonic terms, it'd look something like: return Object.hashCode(this); } } Ideas?

  • Model-layer validation in Doctrine, Symfony

    - by Andree
    Hi there, I have a schema.yml containing something similiar to the following: Character: tableName: characters actAs: { Timestampable: ~ } columns: id: { type: integer(4), primary: true, autoincrement: true } name: { type: string(255), notnull: true, notblank: true, minlength: 3 } I define the minlength of the column name to be 3. I created a unit test to test the minlength validation, and I found out that the validation is not working. $character = new Character(); $character->set('name', 'Dw'); $t->ok(! $character->isValid()); # This test failed Can someone tell me what might be the problem here?

  • Nested attributes form for model which belongs_to few models

    I have few models - User, Teacher and TeacherLeader. class User < ActiveRecord::Base attr_accessible ..., :teacher_attributes has_one :teacher has_one :teacher_leader accepts_nested_attributes_for :teacher_leader end class Teacher < ActiveRecord::Base belongs_to :user has_one :teacher_leader end class TeacherLeader < ActiveRecord::Base belongs_to :user belongs_to :teacher end I would like to fill TeacherLeader via nested attributes.

  • Hibernate Communications Link Failure in Restlet-Hibernate Based Java application powered by MySQL

    - by Vatsala
    Let me describe my question - I have a Java application - Hibernate as the DB interfacing layer over MySQL. I get the communications link failure error in my application. The occurence of this error is a very specific case. I get this error , When I leave mysql server unattended for more than approximately 6 hours (i.e. when there are no queries issued to MySQL for more than approximately 6 hours). I am pasting a top 'exception' level description below, and adding a pastebin link for a detailed stacktrace description. javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: Cannot open connection - Caused by: org.hibernate.exception.JDBCConnectionException: Cannot open connection - Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure - The last packet successfully received from the server was 1,274,868,181,212 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. - Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure - The last packet successfully received from the server was 1,274,868,181,212 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. - Caused by: java.net.ConnectException: Connection refused: connect the link to the pastebin for further investigation - http://pastebin.com/4KujAmgD What I understand from these exception statements is that MySQL is refusing to take in any connections after a period of idle/nil activity. I have been reading up a bit about this via google search, and came to know that one of the possible ways to overcome this is to set values for c3p0 properties as c3p0 comes bundled with Hibernate. Specifically, I read from here http://www.mchange.com/projects/c3p0/index.html that setting two properties idleConnectionTestPeriod and preferredTestQuery will solve this for me. But these values dont seem to have had an effect. Is this the correct approach to fixing this? If not, what is the right way to get over this? The following are related Communications Link Failure questions at stackoverflow.com, but I've not found a satisfactory answer in their answers. http://stackoverflow.com/questions/2121829/java-db-communications-link-failure http://stackoverflow.com/questions/298988/how-to-handle-communication-link-failure Note 1 - i dont get this error when I am using my application continuosly. Note 2 - I use JPA with Hibernate and hence my hibernate.dialect,etc hibernate properties reside within the persistence.xml in the META-INF folder (does that prevent the c3p0 properties from working?)

  • Design considerations for a multi-language web application

I don't really know anything about multi-lingual systems, how would you have answered that question?

  • Wizard based feature install in sharepoint 2007?

    - by JL
    I have a feature that gets installed using a WSP package, when the feature is activated, I would like the following to happen: The feature will contain a list definition. When the feature gets activated by an end user (the user physically clicks the feature activation button in site features admin) - I would like a modal dialog to appear then ask the user to provide some additional details. 3.1 The additional details will be supplying a certain number of names. For example Mary, John, Peter. Form logistics I can handle. Once the form is complete that information needs to somehow get back to the feature reciever, so that I can then take the base list definition, and use it as a template to create list instances for all the names supplied - so if user had supplied Mary and Peter, then 2 list instances will be created when this feature is activated. Is any of this possible with MOSS 2007? Thank you

  • Problems using User model in django unit tests

  • Android lifecycle of thread-based game

    - by ehehhh
    I ran into a bit of trouble while trying to get my game to work correctly after being put to the background by the user or a phone call for example. My app has a SurfaceView class called GameView, which has the onDraw() method to do all the necessary drawing for my game and two threads - one for calling the onDraw() and one for doing the necessary calculations for the game's logic. I succesfully implemented onPause() and onResume(). (I paused both threads when back button was pressed and resumed them after user cancelled in the AlertDialog.) Now I would like to have the game paused the same way when onStop() gets called. I put both threads on pause and saved my characters location in the savedInstanceState, but when I start my app again, no method gets called (I checked with Logcat). I believe onRestart() should be called first, then onStart() and then onResume(), but none of that happens. What am I doing wrong? (Didn't include any code, because it seems to be a problem of me not understanding the lifecycle, not a problem in code. If it seems necessary, I'll post the parts you request.)

  • Terminal-based snake game: input thread manipulates output

    - by enlightened
    I'm writing a snake game for the terminal, i.e. output via print. The following works just fine: while status[snake_monad] do print to_string draw canvas, compose_all([ frame, specs, snake_to_hash(snake[snake_monad]) ]) turn! snake_monad, get_dir move! snake_monad, specs sleep 0.25 end But I don't want the turn!ing to block, of course. So I put it into a new Thread and let it loop: Thread.new do loop do turn! snake_monad, get_dir end end while status[snake_monad] do ... # no turn! here ... end Which also works logically (the snake is turning), but the output is somehow interspersed with newlines. As soon as I kill the input thread (^C) it looks normal again. So why and how does the thread have any effect on my output? And how do I work around this issue? (I don't know much about threads, even less about them in ruby. Input and output concurrently on the same terminal make the matter worse, I guess...) Also (not really important): Wanting my program as pure as possible, would it be somewhat easily possible to get the input non-blockingly while passing everything around? Thank you!

  • how to insert based on the date

    - by Gaolai Peng
    I have a table table1 (account, last_contact_date, insert_date), account and last_contact_date are primary keys. The insert_date is set with the time the recored being added by calling getdate(). I also have a temporary table #temp(account, last_contact_date) which I use to update the table1. Here are sample data: table1 account last_contact_date insert_date 1 2012-09-01 2012-09-28 2 2012-09-01 2012-09-28 3 2012-09-01 2012-09-28 #temp account last_contact_date 1 2012-09-27 2 2012-09-27 3 2012-08-01 The result table depends on the inserting date. If the date is 2012-09-28, the result will be table1 account last_contact_date insert_date 1 2012-09-27 2012-09-28 2 2012-09-27 2012-09-28 3 2012-09-01 2012-09-28 If the date is 2012-09-29, the result will be table1 account last_contact_date insert_date 1 2012-09-01 2012-09-28 2 2012-09-01 2012-09-28 3 2012-09-01 2012-09-28 1 2012-09-27 2012-09-29 2 2012-09-27 2012-09-29 Basically the rule is (1) if the inserting date is the same day, i will pick the lastest last_contact_date, otherwise, (2) if the last_contact_date is later than the current last_contact_date, I will insert a new one. How do I write a query for this insert?

  • Rails: Routing to a different controller based on request format

    - by Jimmy Cuadra
    I'm writing an app where I want all requests for HTML to be handled by the same controller action. I have some other routes that are JSON-specific. Here's what my routes look like: Blog::Application.routes.draw do constraints format: :json do resources :posts end match "(*path)" => "web#index" end The problem is that constraints is being interpreted as "this route only works with the specified format" rather than "skip this route and try the next one if the request is not in the specified format." In other words, navigating to /posts in the browser gives me a 406 Not Acceptable because the URL is constrained to the JSON format. Instead, I want it to fall through to web#index if the request is for HTML, and hit the resourceful route if the request is for JSON. How can this be achieved? (Using Rails 3.2.9.)
