  • How to structure an enterprise MVC app, and where does Business Logic go?

    - by James
    I am an MVC newbie. As far as I can tell: Controller: deals with routing requests View: deals with presentation of data Model: looks a whole lot like a Data Access layer Where does the Business Logic go? Take a large enterprise application with: Several different sources of data (WCF, WebServices and ADO) tied together in a data access layer (useing multiple different DTOs). A lot business logic segmented over several dlls. What is an appropriate way for an MVC web application to sit on top of this (in terms of code and project structure)? The example I have seen where everything just goes in the Model folder don't seem like they are appropriate for very large applications. Thanks for any advice!

  • Limit a user to view only associated records in rails

    - by trobrock
    I have an application with three Models (Profile - SubModel - SubSubModel) chained together with has many relationships. I am trying to limit a user, after logging in, to only retrieving records that are associated with their Profile. I am very new to rails and this is what I had been trying in the Profile model has_many :submodels, :conditions => {:profile_id => self.id} but this is returning an empty data set when calling with Profile.find_by_id(1).submodels, how else could I achieve what I am trying to do. Or should I handle this in the controller or view instead, I thought it sounded well suited for the model to handle this.

  • How can I equalize the heights of text input fields?

    - by David
    What is the best way to equalize the height of my <select..> elements and my <input type="text"..> elements? It's proving difficult because of differences in box-sizing models. Google Chrome's user agent stylesheet has this: select { -webkit-box-sizing: border-box; } ..whereas other text input fields use the content box model. Why the difference? Should I perhaps make all of my text-based input fields use the border-box model? BTW, I'm using standards-compliant mode (by using <!DOCTYPE html>).

  • How to allow users to customize a DAL

    - by rsteckly
    Hi, I'm working in ASP.NET in an application where often users want to add fields or change field names. I'd like to be able to have an xml schema in place that is parsed and a dynamic object model created from it that can be accessed throughout the application. My initial reaction is that this is not realistic. I think there is flexibility about the dynamic nature of it. I think the people I'm trying to build this for wouldn't mind recompiling. Even if the app recompiled, I don't know how to abstract away enough in my code access the data to allow for users changing property names, etc. How can you write LINQ when the properties might change? In short, there's two questions here: 1) is there a way to dynamically generate an object model of the database and 2) is there a way to abstract away enough so that code accessing the database doesn't break when properties change?

  • Server 2003 SP2 BSOD caused by fltmgr.sys

    - by MasterMax1313
    I'm running into a problem where a Server 2003 SP2 box has started crashing roughly once an hour, BSODing out with the message that fltmgr.sys is probably the cause. I ran dumpchk.exe on the memory.dmp file, indicating the same thing. Any thoughts on typical root causes? The following is the error code I'm seeing: Error code 0000007e, parameter1 c0000005, parameter2 f723e087, parameter3 f78cea8c, parameter4 f78ce788. After running dumpchk on the memory.dmp file, I get the following note: Probably caused by : fltmgr.sys ( fltmgr!FltGetIrpName+63f ) The full log is here: Microsoft (R) Windows Debugger Version 6.12.0002.633 X86 Copyright (c) Microsoft Corporation.

    I would like to use jtraj to specify a trajectory in a Simulink model. Below are what I attempted to retrieve in the command prompt: Q0 = [1 1 0]; Q1 = [1+0.5*cos(2*20) 1+0.5*sin(2*20) 0]; t = 0:0.1:20; [Q, Qd, Qdd] = jtraj(Q0, Q1, t); However, I don't know how to include such trajectory data in the Simulink model easily. Any comments? Thanks in advance.

  • What can I do to avoid losing original resolution when uploading or exporting photos from Picasa?

    - by Janet Levin
    I'm not a programmer, and/but after multiple email discussions and google searches confirmed the problem I'm describing, and after making changes in picasa preferences with no change in resolution loss (from say, 800kb original image to 235kb after export or upload), I'm at a dead end and thinking the answer may lie among you folks, even though I barely understand the language here.

  • Network Diagramming software options?

    - by Zak
    I've used The Dude to map my network, but I can only export the network map as a graphics file. I've also used Dia and Vision to manually diagram portions of my network. Does anyone out there have a solution where I can do automatic network mapping using a tool like "The Dude", then pull that file over to a manually editable format for cleaning up and/or enhancing in Visio or Dia?

  • ComboBox item reader

    - by Homer
    I have an app that reads the contacts on my phone but I can't export them. I'd like to use another app to read the contents of the controls on the other app. Can someone recommend a good app for this or recommend another method? I know I saw something for this last year on lifehacker.com in a collection of diagnostic tools, but I can't find it now.

  • Create a many to many relationship in Entity Framework skipping extra data in the link table.

    - by Paul Smith
    I would like to model the following many to many relationship. Table A ID Field1 Field2 Table B ID Field1 Field2 LinkTable A_ID B_ID Field_I_want_to_ignore As I understand it, if LinkTable.Field_I_want_to_ignore was not present, the Entity Model Designer would automatically create a Many to Many relationship between entity A and entity B. However, because this field exists in the database the designer won't do it for me. I can delete the Field_I_want_to_ignore from the LinkTable Entity that the designer created for me, but how do I eliminate the LinkTable entity altogether and create the many to many relationship I want? I'm not averse to digging through the XML, just at the moment I can't see how to achieve what I want.

  • rails nested attributes

    - by user342798
    I am using rails 3.0.0.beta3 and I am trying to implement form with nested attributes using :accepts_nested_attributes_for. My form is nested to three levels: Survey Question Answer. Survey has_many Questions, and Question has many Answers. Inside the Survey model, there is :accepts_nested_attributes_for :questions and inside the question mode, there is :accepts_nested_attributes_for :answers Everything is working fine except when I add a new answer to an existing question, it doesn't get created. However, if I make changes to the corresponding question while creating the answer, I can successfully create the answer. This example is exactly similar to a railscast: http://railscasts.com/episodes/197-nested-model-form-part-2 but doesn't work in rails3 (at least in my case). Please let me know if there is any issue with nested attributes in Rails 3. Thanks in advance.

  • How come module-level validators are evaluated only after property-level validators?

    - by jonathanconway
    I'm using the module-level validator: 'PropertiesMustMatch' on my view-model, like so: [PropertiesMustMatch("Password", "PasswordConfirm")] public class HomeIndex { [Required] public string Name { get; set; } public string Password { get; set; } public string PasswordConfirm { get; set; } } I'm noticing that if I submit the form without Name filled in, the ValidationSummary() helper returns only the following error: The Name field is required. However, if I fill in Name, then ValidationSummary() will return a PropertiesMustMatch error: 'Password' and 'PasswordConfirm' do not match. So it looks like the property-level validators are being evaluated first, then the model-level validators. I would much prefer if they were all validated at once, and ValidationSummary would return: The Name field is required. 'Password' and 'PasswordConfirm' do not match. Any ideas what I can do to fix this? I'm studying the MVC 2 source-code to try to determine why this happens.

  • How do I display two different objects in a search?

    - by JZ
    github url I am using a simple search that displays search results: @adds = Add.search(params[:search]) In addition to the search results I'm trying to utilize a method, nearbys(), which displays objects that are close in proximity to the search result. The following method displays objects which are close to 2, but it does not display object 2. How do I display object 2 in conjunction with the nearby objects? @adds = Add.find(2).nearbys(10) While the above code functions, when I use search, @adds = Add.search(params[:search]).nearbys(10) a no method error is returned, undefined methodnearbys' for Array:0x30c3278` How can I search the model for an object AND use the nearbys() method AND display all results returned? Model: def self.search(search) if search find(:all, :conditions => ['address LIKE ?', "%#{search}%"]) # where('address LIKE ?', "%#{search}") else find(:all) end end

  • Rails - operation outside of a rollback

    - by Brian Armstrong
    I have a before_create filter that checks if people are posting too many comments. If they are I want to flag their account. class Comment < ActiveRecord::Base before_create :check_rate_limit def check_rate_limit comments_in_last_minute = self.user.comments.count(:conditions => ["comments.created_at > ?", 1.minute.ago]) if comments_in_last_minute > 2 user.update_attribute :status, "suspended" return false end true end end The before filter returns false to stop the comment from being created. The problem is that this triggers a ROLLBACK which also undoes the changes I made to the user model. What's the correct pattern to accomplish this? Specifically: running a check each time an object is created and being able to edit another model if the check fails.

  • How to use nginx to proxy to a host requiring authentication?

    - by bwizzy
    How can I setup an nginx proxy_pass directive that will also include HTTP Basic authentication information sent to the proxy host? This is an example of the URL I need to proxy to: http://username:[email protected]/export?uuid=1234567890 The end goal is to allow 1 server present files from another server (the one we're proxying to) without exposing the URI of the proxy server. I have this working 90% correct now from following the Nginx config found here: http://kovyrin.net/2010/07/24/nginx-fu-x-accel-redirect-remote/ I just need to add in the HTTP Basic authentication to send to the proxy server

  • Rest API Web Service - iOS

    - by zeekerg
    Its my first time to use web service in iOS. REST was my first choice and I use code igniter to form it. I have my Controller: require APPPATH.'/libraries/REST_Controller.php'; class Sample extends REST_Controller { function example_get() { $this->load->helper('arh'); $this->load->model('users'); $users_array = array(); $users = $this->users->get_all_users(); foreach($users as $user){ $new_array = array( 'id'=>$user->id , 'name'=>$user->name, 'age'=>$user->age, ); array_push( $users_array, $new_array); } $data['users'] = $users_array; if($data) { $this->response($data, 200); } } function user_put() { $this->load->model('users'); $this->users->insertAUser(); $message = array('message' => 'ADDED!'); $this->response($message, 200); } } , using my web browser, accessing the URL http://localhost:8888/restApi/index.php/sample/example/format/json really works fine and gives this output: {"users":[{"id":"1","name":"Porcopio","age":"99"},{"id":"2","name":"Name1","age":"24"},{"id":"3","name":"Porcopio","age":"99"},{"id":"4","name":"Porcopio","age":"99"},{"id":"5","name":"Luna","age":"99"}]} , this gives me a great output using RKRequest by RestKit in my app. The problem goes with the put method. This URL : http://localhost:8888/restApi/index.php/sample/user always give me an error like this: This XML file does not appear to have any style information associated with it. The document tree is shown below. <xml> <status/> <error>Unknown method.</error> This is my Users model <?php class Users extends CI_Model { function __construct() { parent::__construct(); } function get_all_users() { $this->load->database(); $query = $this->db->get('users'); return $query->result(); } function insertAUser(){ $this->load->database(); $data = array('name'=> "Sample Name", 'age'=>"99"); $this->db->insert('users', $data); } } ?> What is the work around for my _put method why am I not inserting anything? Thanks all!

  • LINQ to SQL Could not find key member. Only fails on server.

    - by Adam Carr
    I have a scenario where I am inheriting from an abstract class in my partial linq to sql auto generated class implementation. My base abstract class has an abstract property called ID which I have flagged inside my LINQ to SQL model with the instance modifier override. This works fine locally without any issues. I have also done some development on another machine and it works fine there too (both in VS2008 and using Subversion). I am running CI with TeamCity and the build succeeds and deploys as desired. The problem is when the server tries to hit the database for the first time via the LINQ to SQL data context, it generates the following error. "Could not find key member 'Id' of key 'Id' on type 'CustomType'. The key may be wrong or the field or property on 'CustomType' has changed names." I have tried changing my configuration by not implementing the Id field in my base class but this still fails. Why does it work on both of my DEV machines but not on the server? I am using LINQ to SQL in another project that runs on this server just fine. FYI: LINQ to SQL, SQL 2008, .NET 3.5, SERVER 2008, IIS 7.0 UPDATE I have gone back and added the same table a second time in the same data model but without a base class and have then displayed the results from that table and got no errors. This tells me it has something to do with my base abstract class and the need to flag a property on one of my linq to sql model classes (that belongs to a key relationship) with the instance modifier of override. No answer to this yet but am getting closer. UPDATE I have fixed my issue by simply changing my approach to my problem but I am still interested in why this doesn't work. I created a new WinSrv2008 VPC and patched it, deployed a pre-built version of my site to it and still got the same error. I now assume the issue is like what the person said here, a dependency issue with VS2008. My question is what or what? Will install VS2008 on the VPC to see if it works after that.

  • JTable.setRowHeight prevents me from adding more rows

    - by Brent Parker
    I'm working on a pretty simple Java app in order to learn more about JTables, TableModels, and custom cell renderers. The table is a simple table with 8 columns only with text in them. When you click on an "add" button, a dialog pops up and lets you enter the data for the columns. Now to my problem. One of the columns (the last one) should allow for multiple lines of text. I'm already putting HTML into the field, but it is not wrapping. I did some research and looked into JTable#setRowHeight(). However, once I use setRowHeight, I can no longer add rows to the table. The data is put into the table model, but it does not show in the table. If I remove the setRowHeight line, then it adds data just fine. Is there another step to adding data to my data model that I'm missing? Thanks a lot!

  • Catch database exception in Kohana

    - by danilo
    I'm using Kohana 2. I would like to catch a database exception to prevent an error page when no connection to the server can be established. The error displayed is system/libraries/drivers/Database/Mysql.php [61]: mysql_connect() [function.mysql-connect]: Lost connection to MySQL server at 'reading initial communication packet', system error: 110 The database server is not reachable at all at this point. I'm doing this from a model. I tried both public function __construct() { // load database library into $this->db try { parent::__construct(); } catch (Exception $e) { die('Database error occured'); } } as well as try { $hoststatus = $this->db->query('SELECT x FROM y WHERE z;'); } catch (Exception $e) { die('Database error occured'); } ...but none of them seemed to work. It seems as if no exception gets passed on from the main model. Is there another way to catch the database error and use my own error handling?

  • Django and conditional aggregates

    - by piquadrat
    I have two models, authors and articles: class Author(models.Model): name = models.CharField('name', max_length=100) class Article(models.Model) title = models.CharField('title', max_length=100) pubdate = models.DateTimeField('publication date') authors = models.ManyToManyField(Author) Now I want to select all authors and annotate them with their respective article count. That's a piece of cake with Django's aggregates. Problem is, it should only count the articles that are already published. According to ticket 11305 in the Django ticket tracker, this is not yet possible. I tried to use the CountIf annotation mentioned in that ticket, but it doesn't quote the datetime string and doesn't make all the joins it would need. So, what's the best solution, other than writing custom SQL?
