  • I am having trouble with my first project in ruby on rails

    - by Sebastian
    Here's my index action in the books controller: http://pastebin.com/XdtGRQKV Here's the view for the action i just mentioned: http://pastebin.com/nQFy400m Here's the result without being logged in: http://i.imgur.com/rQoiw.jpg Here's the result when i'm logged in with the user 'admin': http://i.imgur.com/E1CUr.jpg So the problem is that, in the view, before line 25 the 'user' variable seems to be empty ( or not loaded), and after line 25 the variable 'user' has the expected values. I have tried initializing a variable in the index method of the books controller but get exactly the same results. Thanks in advance! BTW had to make the links text because of stackoverflow limit.

  • Apache Rewrite Excluding Assets Directory

    - by Midiane
    Hi all I'm writing a mini-MVC application. App architecture: actions/ templates/ site/ app/ styles/ images/ scripts/ So far, I've got a controller working properly, taking in all requests. However, javascript files are not being rendered properly in the browser; I'm getting a 404 Not Found when I try to load the file in the browser. Here is my current Directory config in a vhost file: DirectoryIndex index.php RewriteEngine On RewriteBase /apps/ecatalogue RewriteRule ^scripts/(.*) - [NC,L] <--- Rule not working RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php [NC,L,QSA] I can confirm everything else works; I just need apache to ignore anything in scripts so the file can be loaded normally without being processed by the controller. Your help is appreciated.

  • Conditional value for ActiveRecord create method only

    - by Steve Wright
    I have a form where I have an administrator creating new users. The form uses the User model I created (login, password, first_name, etc...). For the last field on the form, I want to have a checkbox that doesn't need to be stored as part of the User record, but it is needed for the controller. This will control whether or not the newly created user will receive a welcome email or not. def create @user = User.new(params[:user]) if @user.save if @user.send_welcome_email UserMailer.welcome_email(@user).deliver end redirect_to(admin_users_url, :notice => "User #{@user.name} was successfully created.") else render :action => "new" end end In my view (haml) I am trying to access it like this: %p Send Welcome Email? = f.check_box :send_welcome_email I tried to make this an attr_accessible: :send_welcome_email but the controller does not recognize it. I get an undefined method 'send_welcome_email' for #&lt;User:0x00000100d080a8&gt; I would like it to look like this: What is the best way to get this working:

  • Joomla forwarding code to the View...is this the correct way to do it?

    - by jax
    Here are some sample methods from my Controller class. Now when the user clicks the New button $task=add is sent to the Controller and the add() method is called. As you can see it does not really do anything, it just creates a url and forwards it off to the correct view. Is this the correct way of doing things in the MVC pattern? /** * New button was pressed */ function add() { $link = JRoute::_('index.php?option=com_myapp&c=apps&view=editapp&cid[]=', false); $this->setRedirect($link); } /** * Edit button was pressed - just use the first selection for editing */ function edit() { $cid = JRequest::getVar( 'cid', array(0), '', 'array' ); $id = $cid[0]; $link = JRoute::_("index.php?option=com_myapp&c=apps&view=editapp&cid[]=$id", false); $this->setRedirect($link); }

  • Searching in Rails 3

    - by cbarton
    Here is the situation: I have the need to search for specifics or generals, much like expedia.com or your local library catalog search. In that there are fields that may or may not be filled out based on the individual need. It acts much like an "advanced search page". I have all of that code done for the models/controller and such and have it setup with a Searches controller along with matching model and views. The question that I have is there a way to cut down the amount of parameters posted to GET so that the url isn't search?search[:a]=""+search[:b]=""+search[:c]="x"... plus the unicode checkmark. I only want the filled out fields to be shown in the response link especially minus the checkmark. cbarton

  • Show a modal right after signup?

    - by user1494756
    When a user signup at my page I want them to be redirected to the root_path(this I have figured out how to do in the user controller). But then I want a modal to show in front of this page(and this should only happen the first time the user see this root/home page(like a flash message). Here is my create method in the user controller: def create @user = User.new(params[:user]) if @user.save sign_in @user redirect_to root_path else render 'new' end end The modal is placed in app/views/layouts/_modal.html.erb. Does anybody know how to make this happen? (Jepp, I am a newbie :)

  • asp.net mvc 2 multiple partial view

    - by 303
    Hey Guys, I have a contoller that renders 3 different views. But I also have a common part (div) for every view. I thought that I can create an UserControl with own controller and include that control on my views (New controller and view as controll). How should I use that UserControl? Should it be a partial view? Or different approach - can I have multiple partial views on one page? I've been searching the web for the last view days and haven't found working solution that suits me. Also I want to use Strongly Typed views/data. Cheers

  • Bandwidth Monitoring in asp.net

    - by asifch
    HI, We are developing a multi-tenant application in Asp.Net with separate DB for each tenant, in which one of the requirement is to monitor the bandwidth usage for each tenant, i have tried to search but not found much help on the topic,we want to monitor exactly how much bandwidth is being used for each tenant while each tenant can have its own top level domain or a sub domain or a combination of both. so what are the available options, the ones which i can think of can be 1. IIS Log Monitoring means a separate application which will calculate the bandwidth for each tenant. 2. Log Each Request and Response for a tenant from within the application and then calculate the total bandwidth usage based on that. 3. Use some third part components if available So what do you think will be the best approach, also if there is any other way to do this.

  • What are the differences between MVP, Presentation Model, MVVM and MVC?

    - by Nicholas
    I have a pretty good idea how each of these patterns work some of the minor differences between them, but are they really all that different from each other? It seems to me that the Presenter, Presentation Model, ViewModel and Controller are essentially the same concept. Why couldn't I classify all of these concepts as controllers? I feel like it might simplify the entire idea a great deal. Can anyone give a clear description of their differences? I want to clarify that I do understand how the patterns work, and have implemented most of them in one technology or another. What I am really looking for is someone's experience with one of these patterns, and why they would not consider their ViewModel a controller for instance.

  • Rendering Views as String with Spring MVC and Apache Tiles

    - by lynxforest
    I am trying to reuse some of my tiles in a controller which is returning a json response to the client. I would like to return a json response similar to the following format: { 'success': <true or false>, 'response': <the contents of an apache tile> } In my controller I would like to perform logic similar to this pseudocode: boolean valid = validator.validate(modelObj) String response = "" if(valid){ response = successView.render() // im looking for a way to actually accomplish // this, where the successView is the apache tiles view. // I would also need to pass a model map to the view somehow. }else{ response = errorView.render() } writeJsonResponse(httpResponse, /* a Map whose json representation looks like the one I described above. */)

  • Play 2.0 javaToDo tutorial doesn't compile

    - by chsn
    I'm trying to follow the Play2.0 JavaToDO tutorial and for some reason it just doesn't want to work. Have looked through stackoverflow and other online resources, but haven't find an answer to this and it's driving me crazy. Attached code of the Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { static Form<Task> taskForm = form(Task.class); public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result newTask() { return TODO; } public static Result deleteTask(Long id) { return TODO; } } Attached code of the Task java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task { public Long id; @Required public String label; // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create task public static void create(Task task) { task.create(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } // create new task public static Result newTask() { Form<Task> filledForm = taskForm.bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.create(filledForm.get()); return redirect(routes.Application.tasks()); } } } I get a compile error on Task.java on the line static Form<Task> taskForm = form(Task.class); As I'm working on eclipse (the project is eclipsified before import), it's telling me that taskForm cannot be resolved and it also underlines every play 2 command e.g. "render(), redirect(), bindFromRequest()" asking me to create a method for it. Any ideas how to solve the compilations error and also how to get Eclipse to recognize the play2 commands? EDIT: updated Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { // create new task public static Result newTask() { Form<Task> filledForm = form(Task.class).bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.newTask(filledForm.get()); return redirect(routes.Application.tasks()); } } public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result deleteTask(Long id) { return TODO; } } Updated task.java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task extends Model { public Long id; @Required public String label; // Define a taskForm static Form<Task> taskForm = form(Task.class); // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create new task public static Result newTask(Task newTask) { save(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } }

  • Problems using the Razor model when creating my knockout ViewModel

    I'm having problems with using the Model in a javascript call when setting up my knockout VM.. @model List<AdminGui.Models.Domain> <script src="http://ajax.aspnetcdn.com/ajax/knockout/knockout-2.2.1.js" type="text/javascript"></script> <script type="text/javascript"> function ViewModel() { var self = this; self.domains = ko.observableArray( ko.utils.arrayMap(@Model, function(item) { return new Domain(item.guid, item.description, item.namespaces); })); } I get a syntax error on @Model in the ko.utils.arrayMap call. I suspect it might be my Razor-fu that is lacking... :)

  • How do you render a rails partial that is outside of a namespace in a view that is inside of a namespace?

    - by iand675
    I've got a 'static' controller and static views that are pages that don't utilize ruby in their views. For these pages, I have a sitemap partial that is generated programatically and used in the application layout file. Namespaced routes still use the application layout file but are taking the static routes and trying to namespace them too. Here's the relevant portion of the route file: namespace :admin do resources :verse_categories resources :verses resources :songs resources :flowers resources :visits, :except => [:new, :create] end match ':action' => 'static' root :to => 'static#home' Here's the error I'm getting: No route matches {:controller=>"admin/static", :action=>"about"} Note that about is one of the static pages that the sitemap partial uses. So, how can I resolve this routing issue so that it's not trying to find my static sites inside of the admin namespace? Any help would be appreciated!

  • Namespace with index action in Rails

    - by yuval
    I have an admin controller located inside /controllers/admin/admin_controller.rb I also have a pages controller located inside /controllers/admin/pages_controller.rb In my routes.rb file, I have the following: map.namespace :admin do |admin| admin.resources :pages end When the user goes to localhost:3000/admin, I'd like the user to see a page with a link to /admin/pages (Pages CRUD) and to / (To go back home). Since I am using a namespace, I cannot have an index action for /admin. How would I get this done and still have my controllers located inside my /controllers/admin folder (rather than using admin as a map.resources component and a has_many association to pages). Please note I am only interested in the show action of admin. Thank you!

  • Symfony2 same form, different entities NOT related

    - by user1381537
    I'm trying to write one form for submitting against MySQL DB, but I can't get it working, I've tried a lot of things (separate forms, create an ->add('foo', new foo()) to a field, and trying to parse plain SQL with a normal HTML form is my only solution, which is obviously not the best. This is my DB structure: As you can see I need to insert the comments textarea to ticketcomments among the user who wrote it, etc. On crmentity the description field. Then on ticketcf the fields that I need to submit from form, are this (because you wont know if I don't tell you because of the field names): tcf.cf594 AS Type, tcf.cf675 AS Suscription, tcf.cf770 AS ID_PRODUCT, tcf.cf746 AS NotificationDate, tcf.cf747 AS ResponseDate, tcf.cf748 AS ResolutionDate, And, of course, every table needs to have the same ticketid id for the submitted form, so we can retrieve it with one simple query. It will be easy to do with plain SQL instead of using DQL and Symfony2 forms, but is not a good way to do it. Also, here's my "Ticket list" query, if you need it to have it more clear... SELECT t.ticketNo AS Ticket, t.title AS Asunto, t.status AS Estado, t.updateLog AS LOG, t.hours AS Horas, t.solution AS Solucion, t.priority AS Prioridad, tcf.cf594 AS Tipo, tcf.cf675 AS Suscripcion, tcf.cf770 AS IDPROD, tcf.cf746 AS F_Noti, tcf.cf747 AS F_Resp, tcf.cf748 AS F_Reso, CONCAT (cd.firstname, cd.lastname) AS Contacto, crm.description AS Descripcion, crm.crmid AS id FROM WbsGoclientsBundle:VtigerTroubletickets t INNER JOIN WbsGoclientsBundle:VtigerTicketcf tcf WITH t.ticketid = tcf.ticketid INNER JOIN WbsGoclientsBundle:VtigerContactdetails cd WITH t.parentId = cd.contactid INNER JOIN WbsGoclientsBundle:VtigerCrmentity crm WITH t.ticketid = crm.crmid WHERE t.parentId IN ( SELECT cd1.contactid FROM WbsGoclientsBundle:VtigerContactdetails cd1 WHERE cd1.accountid = ( SELECT cd2.accountid FROM WbsGoclientsBundle:VtigerContactdetails cd2 WHERE cd2.contactid = :contactid)) AND t.status <> \'Closed\' And also "Ticket details" query (which is not in DQL format yet, only SQL) is so simple, it only retrieve the comments field and createdtime from ticketcomments appended to this query so we have all the fields... Thank you. This is a test form, using troubletickets and ticketcomments, it's returning errores because I can't set a comments field because troubletickets doesn't has it, but I need that field to be submitted to ticketcomments ...

  • single sign on in asp.net

    - by gopal
    Hi , We have developed implemented single sign on methodology to authenticate user. When a page is requested, if it is not authenticated then a login page will be redirected. Once they logged in the requested page will be shown. this is working when we don't assign a domain to the virtual directory. But when we assign the domain to virtual directory after the authentication the application is not redirecting to the requested page. We are using FormsAuthentication.GetRedirectUrl method to redirect the requested page. Why this is happening? How can we resolve this issue?

  • Teacher confused about MVC?

    - by Gideon
    I have an assignment to create a game in java using MVC as a pattern. The thing is that stuff I read about MVC aren't really what the teacher is telling me. What I read is that the Model are the information objects, they are manipulated by the controllers. So in a game the controller mutates the placement of the objects and check if there is any collision etc. What my teacher told me is that I should put everything that is universal to the platform in the models and the controllers should only tell the model which input is given. That means the game loop will be in a model class, but also collision checks etc. So what I get from his story is that the View is the screen, the Controller is the unput handeler, and the Model is the rest. Can someone point me in the right direction?

  • Devise role based routing

    - by teknull
    I have an app with multiple users. Each user as a theoretical role (user, client, etc). I've designed a view/controller for each user type. I want to be able to login each type of user do a different root url and lock them to it. Originally I was going to add a column to Users in Devise called role and so I can differentiate the users. The problem I'm having is how to say in routes.rb if current_user.role == "client" root :to = 'controller#index' Once they are logged in to the page I also want to keep them from being able to visit any of my other paths ie: domain.com/calls domain.com/units I've been looking into cancan to run alongside Devise but I'm not sure if this is the answer.

  • why is link generated in YUI javascript failing to render in rails?

    - by pmneve
    Using YAHOO.widget.treeview to generate a table with three levels of data: module, submodule, and detail. If there is an image associated with a detail row the javascript generates a link: "<td><a href=\"/screenshot/show/" + rowData.id + "\">Screenshot</a></td>" that is appended to the html for the row. The url is generated correctly and the link appears. When clicked nothing happens except the word 'Done' appears in the browser status bar. Am calling the very same url from another page that does not use javascript and the screenshot page appears as expected. Here is the controller. class ScreenshotController < ApplicationController def show if @detail.screen_path.length 1 @imagePath = "#{RAILS_ROOT}" + "/private/#{Company.find(@detail.company_id).subdir}/" + "#{Project.find(@detail.project_id).subdir}/screenshot/" + "#{@detail.screen_path}" send_file ( @imagePath, :type = 'image/jpeg', :disposition = 'inline') end end end A sample url: http://localhost:3004/screenshot/show/20854 This code from show.html.erb belonging to the detail model works: <%= link_to 'View', :controller = 'screenshot', :id = @detail.id, :action = 'show' % Any ideas???

  • Imitating Multiple Inheritance in PHP

    - by fabieno
    I am working on my own MVC framework and found myself stuck. I need the following construction: Controller -- Backend_Controller -- Backend_Crud_Controller -- Frontend_Controller -- Frontend_Crud_Controller Both 'Backend_Crud_Controller' and 'Frontend_Crud_Controller' have the same functionality and thus they should extend another class named 'Base_Crud_Controller', the only difference comes from the 'Backend/Frontend' Controllers which implement different mechanisms. Basically they should inherit both classes but my problem is that 'Backend/Frontend' controller doesn't necessarily extend 'Base_Crud_Controller'. I know multiple inheritance doesn't exist in PHP but I am looking for a solution, I choose to refrain Mixins (like in Symfony) as I don't consider that an elegant solution. Interfaces do not suit me as all of these end up as concrete classes that should implement methods.

  • Subprocess with variables & Command from different class

    - by Pastelinux
    source: http://pastebin.com/utL7Ebeq My thinking is that if i run from controller class "main" it will allow me to take the "data" from Class "model", def "filename". It doesn't seem to work. As you can see below what i mean class Controller: def __init__(self): self.model = Model() self.view = View() def main(self): data = self.model.filename() self.view.tcpdump(data) class View: def tcpdump(self, command): subprocess.call(command.split(), shell=False) When i run my code i get this error: subprocess.call(command.split(), shell=False) AttributeError: 'NoneType' object has no attribute 'split' My guess means that its not picking up command (look at source for reference) or that its not getting command with variables. But i know the error when variables are not being picked up so i don't think it is that. My question is, from what i have thus far, how do i from "class view" grab "command" for my subprocesses to run. Thanks~ John Riselvato
