  • Automating rake doc:app

    - by jerhinesmith
    For you rails programmers, what's the easiest way to keep your RDoc files up-to-date? I know I can run rake doc:app manually, but I really don't feel like adding a manual step to the check-in process, and since we're already using cruisecontrolrb to handle deployment and testing automation, it seems like there should be an easy way to regenerate these files on check-in. Is anyone already automating rake doc:app? And, if so, what are your suggestions?

  • Many to Many Association Tables - Is it customary to put additional columns in these tables?

    - by Randy Minder
    We've encountered the following situation in our database. We have table 'A' and table 'B' which have a M2M relationship. The association table is named 'AB' and contains a FK column to table 'A' and a FK column to table 'B'. Now we've identified a need to store additional data about this association. For example, a date when the association occurred, and who made the association etc. We've decided to put these additional columns in the 'AB' association table. However, something tells me this is frowned upon by database purists. On the other hand, it makes no sense to us to create yet an additional table to store this associated data. What's the prevailing thought on this?

  • Why Does Piping Binary Text to the Screen often Horck a Terminal

    - by Alan Storm
    Imaginary Situation: You’ve used mysqldump to create a backup of a mysql database. This database has columns that are blobs. That means your “text” dump files contains both strings and binary data (binary data stored as strings?) If you cat this file to the screen $ cat dump.mysql you’ll often get unexpected results. The terminal will start beeping, and then the output finishes scrolling by you’ll often have garbage chacters entered on your terminal as through you’d typed them, and sometimes your prompts and anything you type will be garbage characters. Why does this happen? Put another way, I think I’m looking for an overview of what’s actually happening when you store binary strings into a file, and when you cat those files, and when the results of the cat are reported to the terminal, and any other steps I’m missing.

  • Call private method in Flex, Actionscript.

    - by core07
    I need it in FlexUnit to test private methods. Is there any possibility to do this via reflection by using describeType or maybe flexUnit has some build in facility? I dislike artificial limitation that i cannot test private functions, it greatly reduces flexibility. Yes it is good design for me to test private functions, so please do not advise me to refactor my code. I do not want to break the encapsulation for the sake of unit testing.

  • Dependency Injection mechanism

    - by abc
    The advantage of inversion of control is that it decouples objects from specific lookup mechanisms and implementations of the objects it depends on. As a result, more flexibility is obtained for production applications as well as for testing. what does it mean actually ?

  • How sophisticated should be DAL?

    - by Andrew Florko
    Basically, DAL (Data Access Layer) should provide simple CRUD (Create/Read/Update/Delete) methods but I always have a temptation to create more sophisticated methods in order to minimize database access roundtrips from Business Logic Layer. What do you think about following extensions to CRUD (most of them are OK I suppose): Read: GetById, GetByName, GetPaged, GetByFilter... e.t.c. methods Create: GetOrCreate methods (model entity is returned from DB or created if not found and returned), Create(lots-of-relations) instead of Create and multiple AssignTo methods calls Update: Merge methods (entities list are updated, created and deleted in one call) Delete: Delete(bool children) - optional children delete, Cleanup methods Where do you usually implement Entity Cache capabilities? DAL or BLL? (My choice is BLL, but I have seen DAL implementations also) Where is the boundary when you decide: this operation is too specific so I should implement it in Business Logic Layer as DAL multiple calls? I often found insufficient BLL operations that were implemented in dozen database roundtrips because developer was afraid to create a bit more sophisticated DAL. Thank you in advance!

  • trying to use ActiveRecord with Sinatra, Migration fails question

    - by David Lazar
    Hi, running Sinatra 1.0, I wanted to add a database table to my program. In my Rakefile I have a task task :environment do ActiveRecord::Base.establish_connection(YAML::load(File.open('config/database.yml'))["development"]) end I have a migration task in my namespace that calls the migration code: namespace :related_products do desc "run any migrations we may have in db/migrate" task :migrate => :environment do ActiveRecord::Migrator.migrate('db/migrate', ENV["VERSION"] ? ENV["VERSION"].to_i : nil ) end My console pukes out an error when the call to ActiveRecord::MIgrator.migrate() is made. rake aborted! undefined method `info' for nil:NilClass The migration code itself is pretty simple... and presents me with no clues as to what this missing info class is. class CreateStores < ActiveRecord::Migration def self.up create_table :stores do |t| t.string :name t.string :access_url t.timestamps end end def self.down drop_table :stores end end I am a little mystified here and am looking for some clues as to what might be wrong. Thanks!

  • where should I put the EF entity and data annotations in asp.net mvc + entity framework project

    - by giddy
    So I have a DataEntity class generated by EntityFramework4 for my sqlexpress08 database. This data context is exposed via a WCF Data Service/Odata to silverlight and win forms clients. Should the data entities + edmx file (generated by EF4) go in a separate class library? The problem here then is I would specify data annotations for a few entities and then some of them would require specific MVC attributes (like CompareAttribute) so the class library would also reference mvc dlls. There also happen to be entity users which will be encapsulated or wrapped into an IIdentity in the website. So its pretty tied to the mvc website. Or Should it maybe go in a Base folder in the mvc project itself? Mostly the website is data driven around the database, like approve users, change global settings etc. The real business happens in the silverlight and win forms apps. Im using mvc3 rc2 with Razor. Thanks

  • SQLAlchemy - how to map against a read-only (or calculated) property

    - by Jeff Peck
    I'm trying to figure out how to map against a simple read-only property and have that property fire when I save to the database. A contrived example should make this more clear. First, a simple table: meta = MetaData() foo_table = Table('foo', meta, Column('id', String(3), primary_key=True), Column('description', String(64), nullable=False), Column('calculated_value', Integer, nullable=False), ) What I want to do is set up a class with a read-only property that will insert into the calculated_value column for me when I call session.commit()... import datetime def Foo(object): def __init__(self, id, description): self.id = id self.description = description @property def calculated_value(self): self._calculated_value = datetime.datetime.now().second + 10 return self._calculated_value According to the sqlalchemy docs, I think I am supposed to map this like so: mapper(Foo, foo_table, properties = { 'calculated_value' : synonym('_calculated_value', map_column=True) }) The problem with this is that _calculated_value is None until you access the calculated_value property. It appears that SQLAlchemy is not calling the property on insertion into the database, so I'm getting a None value instead. What is the correct way to map this so that the result of the "calculated_value" property is inserted into the foo table's "calculated_value" column?

  • .net converting bytearray to double[]

    - by AJ
    Hello, I am working with a database from a legacy app which stores 24 floating point values (doubles) as a byte array of length 192, so 8 bytes per value. This byte array is stored in a column of type image in a SQL Server 2005 database. In my .net app I need to read this byte array and convert it to a array of type Double[24]. I can access the field easy enough reader.GetBytes(...) but how to convert the returned ByteArray to Double[24] Any ideas? Thanks, AJ

  • Mixing Transaction Script pattern with DDD/CQRS

    - by Herman
    Hi all, Here is the situation, in order to support our legacy system, we need to insert to a table whenever a user logs in. This is basically an CRUD operation, so it doesn't really make sense to create repository/entity/command/event for this since this doesn't tie to any business rules at all. The only benefit to create a CQRS command is that this database write can happen asynchronously under that model. Which is a better route to take? Use CQRS, and then call a stored proc. when handling that command? Just call database directly in the controller (I am using asp.net mvc)

  • SQL Access INSERT INTO Autonumber Field

    - by KrazyKash
    I'm trying to make a visual basic application which is connected to a Microsoft Access Database using OLEDB. Inside my database I have a user table with the following layout ID - Autonumber Username - Text Password - Text Email - Text To insert data into the table I use the following query INSERT INTO Users (Username, Password, Email) VALUES ('004606', 'Password', '[email protected]') However I seem to get an error with this statement and according to VB it's a syntax error. But then I tried to use the following query INSERT INTO Users (Username) Values ('004606') This query seemed to work absolutely fine... So the problem is I can insert into just one field but not all 3 (excluding the ID field because it's an autonumber). Any help would be appreciated, Thanks

  • Most elegant way to morph this sequence

    - by Ed Woodcock
    Hi folks: I've got the Day of the week stored in a database table (that I do not control), and I need to use it in my code. Problem is, I want to use the System.DayOfWeek enum for representation for this, and the sequences are not the same. In the database, it's as follows: 1 2 3 4 5 6 7 S M T W T F S I need it as follows: 0 1 2 3 4 5 6 M T W T F S S What's the most elegant way to do this? for example, I could do: i = dayOfWeek; i = i - 2; if (i < 0) { i = 6; } but that's a bit inelegant. Any suggestions?

  • What is the best PHP framework for building a website around a heavily relational PostgreSQL databas

    - by Kenaniah
    First of all, the framework of choice needs to have excellent support for PostgreSQL. I don't care about MySQL because it doesn't have half of the features the application I will be porting requires. (And when I say excellent support, I mean that their approach to database drivers has not been solely trained in MySQL). The ideal framework: Should take full advantage of PHP 5.3 and PostgreSQL 8.4 features Should support new technologies such as OpenID and social networking Should support complex relationships between database relations Should have an intelligent validation system Should have a basic library of helpful views (such as pagination, navigation, etc) Should probably be MVC based Should have excellent documentation and an active development community Should namespace classes intelligently What I'm looking for might be more of a library of utilities, as I really don't want to be restricted by the framework in what I can and can not do. I have my own small library of core classes that take care of business logic, and I will most likely want to integrate those with the new framework as well. Thanks!

  • Entity Framework doesn't like 0..1 to * relationships.

    - by Orion Adrian
    I have a database framework where I have two tables. The first table has a single column that is an identity and primary key. The second table contains two columns. One is a nvarchar primary key and the other is a nullable foreign key to the first table. On the default import of the database I get the following error: Condition cannot be specified for Column member 'ForeignKeyId' because it is marked with a 'Computed' or 'Identity' StoreGeneratedPattern. where ForeignKeyId is the second foreign key reference in the second table. Is this just something the entity model doesn't do? Or am I missing something?

  • Can SQLAlchemy DateTime Objects Only Be Naive?

    - by Sean M
    I am working with SQLAlchemy, and I'm not yet sure which database I'll use under it, so I want to remain as DB-agnostic as possible. How can I store a timezone-aware datetime object in the DB without tying myself to a specific database? Right now, I'm making sure that times are UTC before I store them in the DB, and converting to localized at display-time, but that feels inelegant and brittle. Is there a DB-agnostic way to get a timezone-aware datetime out of SQLAlchemy instead of getting naive datatime objects out of the DB?

  • Two Survey Questions not populating in survey

    - by user3685991
    Two questions (questions #2 and #3) did not populate in my survey for respondents. All questions, including these two, was mandatory. The question is visible in the preview and when tested (testing was completed eight times). The browser is internet explorer. The survey link is: https://www.surveymonkey.com/s/3YWNTR5 This survey was used for a graduate school Capstone research project. If I could recover the answers to these questions, I would be grateful. Thank you, Jennifer Granger
