Good thing about AngularJS which you need consider before doing Migration. It provides two way binding by only storing variable in scope. Other thing we need write code as compare to JQuery. Implementation in modular way(by creating angular.module) Shift most of the code from Javascript to HTML, that looks code more cleaner. Singleton patterners are … Read more
The reason is this breaking change: DeflateStream, GZipStream, and CryptoStream diverged from typical Stream.Read and Stream.ReadAsync behavior in two ways: They didn’t complete the read operation until either the buffer passed to the read operation was completely filled or the end of the stream was reached. And the new behaviour is: Starting in .NET 6, … Read more
I needed something similar, but didn’t want to pay for (or install) a tool to do it. I created a quick PowerShell script that goes through the project references and spits them out in a yuml.me friendly-format instead: Function Get-ProjectReferences ($rootFolder) { $projectFiles = Get-ChildItem $rootFolder -Filter *.csproj -Recurse $ns = @{ defaultNamespace = “http://schemas.microsoft.com/developer/msbuild/2003” … Read more
Here’s an example: class RenameOldTableToNewTable < ActiveRecord::Migration def self.up rename_table :old_table_name, :new_table_name end def self.down rename_table :new_table_name, :old_table_name end end I had to go and rename the model declaration file manually. Edit: In Rails 3.1 & 4, ActiveRecord::Migration::CommandRecorder knows how to reverse rename_table migrations, so you can do this: class RenameOldTableToNewTable < ActiveRecord::Migration def change … Read more
Use #change_column. change_column(:table_name, :column_name, :date) # a few more examples: change_column(:suppliers, :name, :string, limit: 80) change_column(:accounts, :description, :text) NOTE: the same result can be achieved even outside of db migrations, this might be handy for testing/debugging but this method needs to be used very cautiously: ActiveRecord::Base.connection.change_column(:table_name, :column_name, :date)
No, there is no ClearCase to Git bridge, convertor or adaptor that I know of (retaining the full history, with all its events). It is best to: restrict a git repo to an UCM component (while a Vob can contain multiple component and be way too big for a Git repo to handle) add in … Read more
I reinstalled with the commmand: Install-Package EntityFramework -IncludePrerelease and the problem went away.

Update: See @GwynBleidD’s comment below for the problems this solution can cause, and see @Rockallite’s answer below for an approach that’s more durable to future model changes. Assuming you have a fixture file in <yourapp>/fixtures/initial_data.json Create your empty migration: In Django 1.7: python manage.py makemigrations –empty <yourapp> In Django 1.8+, you can provide a name: … Read more
Migrations provide forward and backward step changes to the database. In a production environment, incremental changes must be made to the database during deploys: migrations provide this functionality with a rollback failsafe. If you run rake db:schema:load on a production server, you’ll end up deleting all your production data. This is a dangerous habit to … Read more
