  • Managing Large Database Entity Models

    - by ChiliYago
    I would like hear how other's are effectively (or not) working with the Visual Studio Entity Designer when many database tables exists. It seems to me that navigating the Designer is tough enough to find what you are looking for with just a few tables but how about a database with say 100 to 200 tables? When a table change is made at the database level how is the model updated? Does it overwrite any manual changes you have made to the model? How would you quickly find an entity in the designer to make a change or inspect a change? Seems unrealistic to be scrolling around looking for specific entity. Thanks for your feedback!

  • ACL implementation

    - by Kirzilla
    First question Please, could you explain me how simpliest ACL could be implemented in MVC. Here is the first approach of using Acl in Controller... <?php class MyController extends Controller { public function myMethod() { //It is just abstract code $acl = new Acl(); $acl->setController('MyController'); $acl->setMethod('myMethod'); $acl->getRole(); if (!$acl->allowed()) die("You're not allowed to do it!"); ... } } ?> It is very bad approach, and it's minus is that we have to add Acl piece of code into each controller's method, but we don't need any additional dependencies! Next approach is to make all controller's methods private and add ACL code into controller's __call method. <?php class MyController extends Controller { private function myMethod() { ... } public function __call($name, $params) { //It is just abstract code $acl = new Acl(); $acl->setController(__CLASS__); $acl->setMethod($name); $acl->getRole(); if (!$acl->allowed()) die("You're not allowed to do it!"); ... } } ?> It is better than previous code, but main minuses are... All controller's methods should be private We have to add ACL code into each controller's __call method. The next approach is to put Acl code into parent Controller, but we still need to keep all child controller's methods private. What is the solution? And what is the best practice? Where should I call Acl functions to decide allow or disallow method to be executed. Second question Second question is about getting role using Acl. Let's imagine that we have guests, users and user's friends. User have restricted access to viewing his profile that only friends can view it. All guests can't view this user's profile. So, here is the logic.. we have to ensure that method being called is profile we have to detect owner of this profile we have to detect is viewer is owner of this profile or no we have to read restriction rules about this profile we have to decide execute or not execute profile method The main question is about detecting owner of profile. We can detect who is owner of profile only executing model's method $model-getOwner(), but Acl do not have access to model. How can we implement this? I hope that my thoughts are clear. Sorry for my English. Thank you.

  • Why is Scaffolding Not Working in Ruby on Rails?

    - by Timmy
    I created a controller and a model. The controller is called "Admin" and the model is called "Album". I edited database.yml with proper info and did the rake db:migrate command which didn't return any errors and did migrate the db inside schema.rb. Inside the controller I wrote: class AdminController < ApplicationController scaffold :album end Next I started my server and went to http://localhost:3000/admin but instead of seeing the typical CRUD page I get the following error: app/controllers/admin_controller.rb:3 Request Parameters: None Show session dump --- flash: !map:ActionController::Flash::FlashHash {} Response Headers: {"cookie"=>[], "Cache-Control"=>"no-cache"} Any idea why?

  • php database session handling problem in IE8!

    - by psyb0rg
    I've got an html page from where Im making this call periodically: function logon(id) { $.get("data.php", { action: 'online', userID: id}, function(data){ $("#msg").html(data); }); } What this does is it calls this SQL script in data.php: $sql = "update user_sessions set expires=(expires + 2) where userID = $userID"; mysql_query($sql, $conn) or die(mysql_error()); echo $sql; I can see by the echo that the sql syntax and values are correct, but THE CHANGES TO THE expires FIELD ARE NOT DONE, ONLY IN IE8!! It works fine in other ff, safari, chrome, ie6 and 7. There is nothing browser specific about making this sql call, but the user_sessions table is used to store PHP's sessions. Im only increasing the session expiry time when the call is made. What in IE8's session handling is preventing the session time from changing? Is there any caching or cookie problem that needs to be changed?

  • .NET 3.5 DataGridView Wont Save To Database

    - by Jimbo
    I have created a test Winforms application in Visual Studio 2008 (SP1) to see just how "RAD" C# and .NET 3.5 can be. So far I have mixed emotions. Added a service-based database to my application (MyDB.mdf) and added two tables - Contact (id [identity], name [varchar] and number [varchar] columns) and Group (id [identity] and name [varchar] columns) Added a DataSource, selected "Database" as the source, used the default connection string as the connection (which points to my database) and selected "All Tables" to be included in the data source and saved as MyDBDataSet Expanded the data source showing my two tables, selected the "Group" table and chose to display it as a DataGridView (from the dropdown option on the right of each entity) and dragged it onto Form1, thus creating a groupBindingNavigator, groupBindingSource, groupTableAdapter, tableAdapterManager, myDBDataset and groupDataGridView Press F5 to test the application, enter the name "Test" under the DataGridView's "name" column and click "Save" on the navigator which has autogenerated code to save the data that looks like this: private void groupBindingNavigatorSaveItem_Click(object sender, EventArgs e) { this.Validate(); this.groupBindingSource.EndEdit(); this.tableAdapterManager.UpdateAll(this.myDBDataSet); } Stop the application and have a look at the database data, you will see no data saved there in the "Group" table. I dont know why and cant find out how to fix it! Googled for about 30 minutes with no luck. The code is auto-generated with the controls, so you'd think that it would work too :)

  • ResultSet and aggregation

    - by kachanov
    Ok, I admit my situation is special There is a data system that supports SQL-92 and JDBC interface However the SQL requets are pretty expensive, and in my application I need to retreive the same data multiple times and aggregate it ("group by") on different fields to show different dimensions of the same data. For example on one screen I have three tables that show the same set or records but aggregated by City (1st grid), by Population (2nd grid), by number of babies (3rd grid) This amounts to 3 SQL queries (which is very slow), UNLESS anyone of you can suggest any idea any library from apache commons or from google code, so that I can select all records into ResultSet and get 3 arrays of data group by different fields from this single ResultSet. Am I'm missing some obvious and unexpected solution to this problem?

I don't know why this is not working with only Competitor model.

  • Selectind DOM elements based on attribute content

    - by sameold
    I have several types of <a> in my document. I'd like to select only the <a> whose title attribute begins with the text "more data ..." like <a title="more data *"> For example given the markup below, I'd like to select the first and second <a>, but skip the third because title doesn't begin with more data, and skip the 4th because <a> doesn't even have a title attribute. <a title="more data some text" href="http://mypage.com/page.html">More</a> <a title="more data other text" href="http://mypage.com/page.html">More</a> <a title="not needed" href="http://mypage.com/page.html">Not needed</a> <a href="http://mypage.com/page.html">Not needed</a> I'm using DOMXPath. How would my query look like? $xpath = new DOMXPath($doc); $q = $xpath->query('//a');

  • Populating an array into a TableView - Thanks in advance.

    - by tssav
    Hello Developers, View not being populated with the array. I would really appreciate if I could get some help. Thanks!! In a tableView I have the following: NSDictionary *cat = [category objectAtIndex:indexPath.row]; cell.textLabel.text = [cat valueForKey:@"reference"]; This populates the tableView with the content of the array from an XML file. There is another array “data” that prints out the content to the debug console and I want to populate another view with this content. But I am having lot of trouble populating the next view with the data array. NSLog(@"cellForRowAtIndexPath-- Reference:%@: Verse:%@", [cat valueForKey:@"reference"], [cat valueForKey:@"data"]); The didSelectRowAtIndexPath method looks like this: Verse *vvc = [[Verse alloc] initWithNibName:@"VerseView" bundle:nil]; vvc.verses = [[category objectAtIndex:indexPath.row] valueForKey:@"verse"]; [self.navigationController pushViewController:vvc animated:YES]; [vvc release]; [tableView deselectRowAtIndexPath:indexPath animated:YES]; In the cellForRowAtIndexPath of the next view I have the following: NSDictionary *cat = [verses objectAtIndex:indexPath.row]; cell.textLabel.text = [cat valueForKey:@"data"]; What I would like is to have the “data” in a textView. I don’t know what’s wrong. Any help would be appreciated!

  • Dynamically changing validations in Rails

    - by user94154
    I have a model with a validation. At runtime, I'd like to change a value of the validation. For example: in the model bid.rb: class Bid ActiveRecord::Base @foo = Foo.find(1) validates_inclusion_of :amt, :in => [email protected], :message => "must be between 1 and #{@foo.bar}" end and in the application_controller (pseudocode): if today == 'wednesday' Foo.update(1, :bar => 10) else Foo.update(1, :bar => 5) end However, this setup isn't working. The "foo" attribute never updates. It seems that the validation code is set only when the dev server starts and then doesn't change.

  • Finding all areas that intersect with a point and vice-versa - PostGIS

    - by ForeignerBR
    I'm developing a project using PostGIS to hold spatial data where I have records that hold geometry point data and records that hold geometry area data. To solve my problem I'm looking for two queries that can take geographic shapes rather than geometric shapes as parameters. For query A I need it to return all points that intersect with a given area. For query B I need it to return all areas that intersect with a given point.

  • JSON datetime to SQL Server database via WCF

    - by moikey
    I have noticed a problem over the past couple of days where my dates submitted to an sql server database are wrong. I have a webpage, where users can book facilities. This webpage takes a name, a date, a start time and an end time(BookingID is required for transactions but generated by database), which I format as a JSON string as follows: {"BookingEnd":"\/Date(2012-26-03 09:00:00.000)\/","BookingID":1,"BookingName":"client test 1","BookingStart":"\/Date(2012-26-03 10:00:00.000)\/","RoomID":4} This is then passed to a WCF service, which handles the database insert as follows: [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, UriTemplate = "createbooking")] void CreateBooking(Booking booking); [DataContract] public class Booking { [DataMember] public int BookingID { get; set; } [DataMember] public string BookingName { get; set; } [DataMember] public DateTime BookingStart { get; set; } [DataMember] public DateTime BookingEnd { get; set; } [DataMember] public int RoomID { get; set; } } Booking.svc public void CreateBooking(Booking booking) { BookingEntity bookingEntity = new BookingEntity() { BookingName = booking.BookingName, BookingStart = booking.BookingStart, BookingEnd = booking.BookingEnd, RoomID = booking.RoomID }; BookingsModel model = new BookingsModel(); model.CreateBooking(bookingEntity); } Booking Model: public void CreateBooking(BookingEntity booking) { using (var conn = new SqlConnection("Data Source=cpm;Initial Catalog=BookingDB;Integrated Security=True")) using (var cmd = conn.CreateCommand()) { conn.Open(); cmd.CommandText = @"IF NOT EXISTS ( SELECT * FROM Bookings WHERE BookingStart = @BookingStart AND BookingEnd = @BookingEnd AND RoomID= @RoomID ) INSERT INTO Bookings ( BookingName, BookingStart, BookingEnd, RoomID ) VALUES ( @BookingName, @BookingStart, @BookingEnd, @RoomID )"; cmd.Parameters.AddWithValue("@BookingName", booking.BookingName); cmd.Parameters.AddWithValue("@BookingStart", booking.BookingStart); cmd.Parameters.AddWithValue("@BookingEnd", booking.BookingEnd); cmd.Parameters.AddWithValue("@RoomID", booking.RoomID); cmd.ExecuteNonQuery(); conn.Close(); } } This updates the database but the time ends up "1970-01-01 00:00:02.013" each time I submit the date in the above json format. However, when I do a query in SQL server management studio with the above date format ("YYYY-MM-DD HH:MM:SS.mmm"), it inserts the correct values. Also, if I submit a millisecond datetime to the wcf, the correct date is being inserted. The problem seems to be with the format I am submitting. I am a little lost with this problem. I don't really see why it is doing this. Any help would be greatly appreciated. Thanks.

  • Session variables not getting set but only in Internet Explorer and not on all machines

    - by gaoshan88
    Logging into a site I'm working on functions as expected on my local machine but fails on the remote server but ONLY in Internet Explorer. The kicker is that it works in IE locally, just not on the remote machine. What in the world could cause this? I have stepped through the code on the remote machine and can see the entered login values being checked in the database, they are found and then a login function is called. This sets two $_SESSION variables and redirects to the main admin page. However, in IE only (and not when run on local machine... this is key) the $_SESSION variables are not present by the time you get to the main admin page. var_dump($_SESSION) gives me what I expect on every browser when I am running this in my local environment and in every browser except IE 6, 7 and 8 when run on the remote server (where I get a null value as if nothing has been set for $_SESSION). This really has me stumped so any advice is appreciated. For an example... in IE, run locally, var_dump gives me: array 'Username' => string 'theusername' length=11 'UserID' => string 'somevalue' length=9 Run on the remote server (IE only... works fine in other browsers) var_dump gives me: array(0){} Code: $User = GetUser($Username, $Password); if ($User->UserID <> "") { // this works so we call Login()... Login($User); // this also works and gives expected results. on to redirect... header("Location: index.php"); // a var_dump at index.php shows that there is no session data at all in IE, remotely. } else { header("Location: login.php"); } function Login($data) { $_SESSION['Username'] = $data->Username; $_SESSION['UserID'] = $data->UserID; // a var dump here gives the expected data in every browser }

  • use JSON variable in jQuery dynamically

  • Best option for Google App Engine Datastore and external database?

    - by Alex
    I need to get an App Engine app talking to and sharing data with an external database, The best option i can come up with is outputting the external database data to an xml file and then processing this in my app engine app and storing it inside the datastore, although the data being shared is sensitive data such as login details so outputting this to an xml file is not exactly a great idea, is it possible for the app engine app to directly query the database? or is there a secure option for using xml files? oh and im using python/django and the external database will be hosted on another domain

  • Is iOS6 simulator buggy when deleting applications?

    - by davsan
    Frequently, when I try to delete an app on the iOS 6 simulator that comes with Xcode 4.5, the simulator freezes. What I do is just long press on the app. Delete dialog doesn't come up and the icons keep on wiggling. Quitting and re-opening the simulator does not help to delete the app. I've tried to delete the app's folder from /Library/Application Support/iPhone Simulator/5.1/Applications folder. Sometimes this helps but sometimes even this doesn't delete the icon from the simulator. This behavior is independent of the iOS version or the device model. It's the same whichever model/iOS I choose. The only thing that helps is using the Reset Contents and Settings option of the simulator. Do you experience the same frustration? If so, have you figured out a workaround besides resetting the simulator completely?

  • devise register confirmation

    - by mattherick
    hello! i have a user and an admin role in my project. i created my authentification with devise, really nice and goot tool for handling the authentification. in my admin role i don´t have any confirmation or something like that. it is really simple and doesn´t make problems. but in my user model i have following things: model: devise :database_authenticatable, :confirmable, :recoverable, :rememberable, :trackable, :validatable, :timeoutable, :registerable # Setup accessible (or protected) attributes for your model attr_accessible :email, :username, :prename, :surname, :phone, :street, :number, :location, :password, :password_confirmation and few validations, but they aren´t relevant this time. my migration looks like following one: class DeviseCreateUsers < ActiveRecord::Migration def self.up create_table(:users) do |t| t.database_authenticatable :null = false t.confirmable t.recoverable t.rememberable t.trackable t.timeoutable t.validateable t.string :username t.string :prename t.string :surname t.string :phone t.string :street t.integer :number t.string :location t.timestamps end add_index :users, :email, :unique => true add_index :users, :confirmation_token, :unique => true add_index :users, :reset_password_token, :unique => true add_index :users, :username, :unique => true add_index :users, :prename, :unique => false add_index :users, :surname, :unique => false add_index :users, :phone, :unique => false add_index :users, :street, :unique => false add_index :users, :number, :unique => false add_index :users, :location, :unique => false end def self.down drop_table :users end end into my route.rb I added following statements: map.devise_for :admins map.devise_for :users, :path_names = { :sign_up = "register", :sign_in = "login" } map.root :controller = "main" and now my problem.. if I register a new user, I fill in all my data in the register form and submit it. After that I get redirected to the controller main with the flash-notice "You have signed up successfully." And I am logged in. But I don´t want to be logged in, because I don´t have confirmed my new user account yet. If I open the console I see the last things in the logs and there I see the confirmation-mail and the text and all stuff, but I am already logged in... I can´t explain why, ... does somebody of you have an idea? If I copy out the confirmation-token from the logs and confirm my account, I can log in, but if I don´t confirm, I also can log in..

  • Servlet doPost() Method setup?

    - by Mark R
    I am interested in creating a web app that uses JSP, Servlets and XML. At the moment I have the following: JSP - Form input. Servlet - Retrieving Form data and sending that data to a java object. Java object (1) - Converts data into XML file....instantiates java object (2). Java object (2) - Sends that file to a database. On the returning side the database will send back another XML file that I will then process using XSLT to display back to the user. Can I place that XSLT code in the orignial Servlets doPost() method? So my doPost()` method would: Retrieve user inputted data from the form on my JSP page. Instantiate a java object to convert that data to XML, in-turn that object will instantiates another object to send the XML file to a database. Converts the resulting XML file sent from the database and displays it for the user. Can one servlet doPost() method handle all of this? If not, how would I set up my application and classes to handle this work flow? Thank you in advance
