• Beginning with Datampper, Association question

  - by Ian

  I'm just diving into Datamapper (and Sinatra) and have a question about associations. Below are some models I have. This is what I want to implemented. I'm having an issue with Workoutitems and Workout. Workout will be managed separately, but Workoutitems has a single workout associated with each row. Workout - just a list of types of workouts (run, lift, situps, etc) Selected workout - this is the name of a set of workouts, along with notes by the user and trainer. It has a collection of N workoutitems Workoutitems - this takes a workout and a number of repetitions to it that go in the workout set. class Workout include DataMapper::Resource property :id, Serial #PK id property :name, String, :length=50,:required=true # workout name property :description, String, :length=255 #workout description end class Selectedworkout include DataMapper::Resource property :id, Serial property :name, String, :length=50, :required=true property :workout_time, String, :length=20 property :user_notes, String, :length=255 property :coach_notes, String, :length=255 has n, :workoutitems end class Workoutitem include DataMapper::Resource property :id, Serial property :reps, String, :length=50, :required=true belongs_to :selectedworkout end

• Setup Padrino with DataMapper and MySQL database

  - by Ivo Sabev

  Hello I am trying to setup a Padrino project using DataMapper and MySQL on my Mac OSX Snow Leopard. I have the necessary gems: dm-core data_objects do_mysql mysql (linked to my original Mac OSX installation) But when I try to start the padrino with PADRINO START from the console, I get the following error: /Users/ivolution/.bundle/ruby/1.9.1/gems/dm-core-0.10.2/lib/dm-core/adapters/mysql_adapter.rb:3:in `require': no such file to load -- do_mysql (LoadError) But as I said I do have do_mysql gem installed so there shouldn't be such error, I did bundle install in my project folder before trying to start Padrino. Any ideas?

• Migrate existing ROR app to GAE

  - by zengr

  I have managed to run a basic rails app1 on App Engine using: http://gist.github.com/268192 So, on my basic app2, I install CE, which works fine on local machine. (communityengine.org) But, when I follow the same steps on my actual app2, where community_engine plugin is installed and all the gems are frozen, the app engine installer script asks for to over write various files like boot.rb, routes.rb, which I don't allow. So, as expected, when I publish the rails + ce app to GAE, it's not published and it also screws the local installation of CE on app2. So, the problem is obvious, CE uses ActiveRecord, and GAE uses DataMapper. So, my question can also be rephrased as: Can we migrate an existing ROR App using Active Record to GAE which uses DataMapper? PS: This is my first project on ROR and GAE.

• Big sinatra problems

  - by Joel M.

  Hi, So I'm having huge trouble with sinatra. Here's what I have: require 'dm-core' DataMapper.setup(:default, ENV['DATABASE_URL'] || 'sqlite3://my.db') class Something include DataMapper::Resource property :id, Serial property :thing, Text property :run_in, Integer property :added_at, DateTime property :to, String def schedule cronify(self.thing+" to "+self.to, "http://url"+self.id.to_s, self.run_in) end def notify text(self.thing, self.to) end end Something.auto_upgrade! The cronify method works. I tested it in irb. Also, the schedule instance method works, I tested it in the console. However, it doesn't work in the route, even though it works in the console. post '/add' do @something = Something.create(blah) #this works fine @something.schedule #this works fine in the console; not in the route. end I've tried everything, from @something.create(blah).schedule (which also works fine in the console, but not in the route), to defining the method cronify inside the sinatra helpers, and even calling cronify directly on the route. Nothing works on the route. What am I doing wrong?

• Test my forms for proper query escaping

  - by Josh K

  CodeIgniter claims do sanitize POST variables. I'm also using DataMapper which I believe also does it's own thing. I would like to double check to make sure it's doing what it's supposed to be doing. How can I do this?

• CodeIgniter model debugging errors

  - by Jono

  I am new to CodeIgniter, and I need a way to get more meaningful error messages. Specifically I am having trouble with some model relationships, but the error is vague. I am willing to try/install anything since I dont know how to fix this relationship. Is there a way to specify how verbose an error message is? Also, this could be related to DataMapper, but I cant tell. I dont care if they are logged or in the browser. In my browser error reads: An Error Was Encountered Unable to relate X with Y. Any more info would be great... which class, line number, a stacktrace. Increasing the log threshold did not help.

• Extend Google AppEngine User in JRuby?

  - by Ryan Montgomery

  I'm working with JRuby and DataMapper running on Google AppEngine. I want to add a property to the AppEngine::User like :active_calendar which is a reference to a Calendar kind. I was able to do something in Python this way using a back reference. Are these possible in JRuby? Is this possible? Do I need to subclass the User? Can I even do that? If so - how? Thanks!

• Heroku: Postgres type operator error after migrating DB from MySQL

  - by sevennineteen

  This is a follow-up to a question I'd asked earlier which phrased this as more of a programming problem than a database problem. http://stackoverflow.com/questions/2935985/postgres-error-with-sinatra-haml-datamapper-on-heroku I believe the problem has been isolated to the storage of the ID column in Heroku's Postgres database after running db:push. In short, my app runs properly on my original MySQL database, but throws Postgres errors on Heroku when executing any query on the ID column, which seems to have been stored in Postgres as TEXT even though it is stored as INT in MySQL. My question is why the ID column is being created as INT in Postgres on the data transfer to Heroku, and whether there's any way for me to prevent this. Here's the output from a heroku console session which demonstrates the issue: Ruby console for myapp.heroku.com >> Post.first.title => "Welcome to First!" >> Post.first.title.class => String >> Post.first.id => 1 >> Post.first.id.class => Fixnum >> Post[1] PostgresError: ERROR: operator does not exist: text = integer LINE 1: ...", "title", "created_at" FROM "posts" WHERE ("id" = 1) ORDER... ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. Query: SELECT "id", "name", "email", "url", "title", "created_at" FROM "posts" WHERE ("id" = 1) ORDER BY "id" LIMIT 1 Thanks!

• Taking the data mapper approach in Zend Framework

  - by Seeker

  Let's assume the following tables setup for a Zend Framework app. user (id) groups (id) groups_users (id, user_id, group_id, join_date) I took the Data Mapper approach to models which basically gives me: Model_User, Model_UsersMapper, Model_DbTable_Users Model_Group, Model_GroupsMapper, Model_DbTable_Groups Model_GroupUser, Model_GroupsUsersMapper, Model_DbTable_GroupsUsers (for holding the relationships which can be seen as aentities; notice the "join_date" property) I'm defining the _referenceMap in Model_DbTable_GroupsUsers: protected $_referenceMap = array ( 'User' => array ( 'columns' => array('user_id'), 'refTableClass' => 'Model_DbTable_Users', 'refColumns' => array('id') ), 'App' => array ( 'columns' => array('group_id'), 'refTableClass' => 'Model_DbTable_Groups', 'refColumns' => array('id') ) ); I'm having these design problems in mind: 1) The Model_Group only mirrors the fields in the groups table. How can I return a collection of groups a user is a member of and also the date the user joined that group for every group? If I just added the property to the domain object, then I'd have to let the group mapper know about it, wouldn't I? 2) Let's say I need to fetch the groups a user belongs to. Where should I put this logic? Model_UsersMapper or Model_GroupsUsersMapper? I also want to make use of the referencing map (dependent tables) mechanism and probably use findManyToManyRowset or findDependentRowset, something like: $result = $this->getDbTable()->find($userId); $row = $result->current(); $groups = $row->findManyToManyRowset( 'Model_DbTable_Groups', 'Model_DbTable_GroupsUsers' ); This would produce two queries when I could have just written it in a single query. I will place this in the Model_GroupsUsersMapper class. An enhancement would be to add a getGroups method to the Model_User domain object which lazily loads the groups when needed by calling the appropriate method in the data mapper, which begs for the second question. Should I allow the domain object know about the data mapper?

• Data Mappers, Models and Images

  - by James

  Hi, I've seen and read plenty of blog posts and forum topics talking about and giving examples of Data Mapper / Model implementations in PHP, but I've not seen any that also deal with saving files/images. I'm currently working on a Zend Framework based project and I'm doing some image manipulation in the model (which is being passed a file path), and then I'm leaving it to the mapper to save that file to the appropriate location - is this common practise? But then, how do you deal with creating say 3 different size images from the one passed in? At the moment I have a "setImage($path_to_tmp_name)" which checks the image type, resizes and then saves back to the original filename. A call to "getImagePath()" then returns the current file path which the data mapper can use and then change with a call to "setImagePath($path)" once it's saved it to the appropriate location, say "/content/my_images". Does this sound practical to you? Also, how would you deal with getting the URL to that image? Do you see that as being something that the model should be providing? It seems to me like that model should worry about where the images are being stored or ultimately how they're accessed through a browser and so I'm inclined to put that in the ini file and just pass the URL prefix to the view through the controller. Does that sound reasonable? I'm using GD for image manipulation - not that that's of any relevance. UPDATE: I've been wondering if the image resizing should be done in the model at all. The model could require that it's provided a "main" image and a "thumb" image, both of certain dimensions. I've thought about creating a "getImageSpecs()" function in the model that would return something that defines the required sizes, then a separate image manipulation class could carry out the resizing and (perhaps in the controller?) and just pass the final paths in to the model using something like "setImagePaths($images)". Any thoughts much appreciated :) James.

• Using an ORM with a database that has no defined relationships?

  - by Ahmad

  Consider a database(MSSQL 2005) that consists of 100+ tables which have primary keys defined to a certain degree. There are 'relationships' between tables, however these are not enforced with foreign key constraints. Consider the following simplified example of typical types of tables I am dealing with. The are clear relations between the User and City and Province tables. However, they key issues is the inconsistent data types in the tables and naming conventions. User: UserRowId [int] PK Name [varchar(50)] CityId [smallint] ProvinceRowId [bigint] City: CityRowId [bigint] PK CityDescription [varchar(100)] Province: ProvinceId [int] PK ProvinceDesc [varchar(50)] I am considering a rewrite of the application (in ASP.net MVC) that uses this data source as is similar in design to MVC storefront. However I am going through a proof of concept phase and this is one of the stumbling blocks I have come across. What are my options in terms of ORM choice that can be easily used and why? Should I even be considering an ORM? (The reason I ask this is that most explanations and tutorials all work with relatively cleanly designed existing databases, or newly created ones when compared to mine. I am thus having a very hard time trying to find a way forward with this problem) There is a huge amount of existing SQL queries, would a datamappper(eg IBatis.net) be more suitable since we could easily modify them to work and reuse the investment already made? I have found this question on SO which indicates to me that an ORM can be used - however I get the impression that this a question of mapping? Note: at the moment, the object model is not clearly defined as it was non-existent. The existing system pretty much did almost everything in SQL or consisted of overly complicated, and numerous queries to complete fucntionality. I am pretty much a noob and have zero experience around ORMs and MVC - so this an awesome learning curve I am on.

• PHP ORM library based on the Data Mapper pattern

  - by Matthieu

  For a PHP application with a complex domain model, I don't want to use the Active Record pattern, I need instead the Data Mapper pattern (as presented in Zend Framework). Do you know any library that could help me for the ORM part, or else a link to a documentation on "how to do it right" ? Thanks

• PHP ORM's, multiple tables and efficiency

  - by sunwukung

  Let's say I have a data mapper function that aggregates multiple tables and generates an object instance from that data. The mapper has a typical save() method which delegates to update/insert. When the mapper executes save - ideally it isolates object fields that have been modified, thus preventing the code from blanket bombing the database. How would you go about this?

• Sinatra Variable Scope

  Take the following code: ### Dependencies require 'rubygems' require 'sinatra' require 'datamapper' ### Configuration config = YAML::load(File.read('config.yml')) name = config['config']['name'] description = config['config']['description'] username = config['config']['username'] password = config['config']['password'] theme = config['config']['theme'] set :public, 'views/themes/#{theme}/static' ### Models DataMapper.setup(:default, "sqlite3://#{Dir.pwd}/marvin.db") class Post include DataMapper::Resource property :id, Serial property :name, String property :body, Text property :created_at, DateTime property :slug, String end class Page include DataMapper::Resource property :id, Serial property :name, String property :body, Text property :slug, String end DataMapper.auto_migrate! ### Controllers get '/' do @posts = Post.get(:order => [ :id_desc ]) haml :"themes/#{theme}/index" end get '/:year/:month/:day/:slug' do year = params[:year] month = params[:month] day = params[:day] slug = params[:slug] haml :"themes/#{theme}/post.haml" end get '/:slug' do haml :"themes/#{theme}/page.haml" end get '/admin' do haml :"admin/index.haml" end I want to make name, and all those variables available to the entire script, as well as the views. I tried making them global variables, but no dice.

• Benchmarking ORM associations

  - by barerd

  I am trying to benchmark two cases of self referential many to many as described in datamapper associations. Both cases consist of an Item clss, which may require many other items. In both cases, I required the ruby benchmark library and source file, created two items and benchmarked require/unrequie functions as below: Benchmark.bmbm do |x| x.report("require:") { item_1.require_item item_2, 10 } x.report("unrequire:") { item_1.unrequire_item item_2 } end To be clear, both functions are datamapper add/modify functions like: componentMaps.create :component_id => item.id, :quantity => quantity componentMaps.all(:component_id => item.id).destroy! and links_to_components.create :component_id => item.id, :quantity => quantity links_to_components.all(:component_id => item.id).destroy! The results are variable and in the range of 0.018001 to 0.022001 for require function in both cases, and 0.006 to 0.01 for unrequire function in both cases. This made me suspicious about the correctness of my test method. Edit I went ahead and compared a "get by primary key case" to a "finding first matching record case" by: (1..10000).each do |i| Item.create :name => "item_#{i}" end Benchmark.bmbm do |x| x.report("Get") { item = Item.get 9712 } x.report("First") { item = Item.first :name => "item_9712" } end where the results were very different like 0 sec compared to 0.0312, as expected. This suggests that the benchmarking works. I wonder whether I benchmarked the two types of associations correctly, and whether a difference between 0.018 and 0.022 sec significant?

• What is the best way to keep database data encrypted with user passwords?

  - by Dan Sosedoff

  Let's say an application has really specific data which belongs to a user, and nobody is supposed to see it except the owner. I use MySQL database with DataMapper ORM mapper. The application is written in Ruby on Sinatra. Application behavior: User signs up for an account. Creates username and password. Logs into his dashboard. Some fields in specific tables must be protected. Basically, I'm looking for auto-encryption for a model properties. Something like this: class Transaction include DataMapper::Resource property :id, Serial property :value, String, :length => 1024, :encrypted => true ... etc ... belongs_to :user end I assume that encryption/decryption on the fly will cause performance problems, but that's ok. At least if that works - I'm fine. Any ideas how to do this?

• Microsoft Word Document Controls not accepting carriage returns

  - by Scott

  So, I have a Microsoft Word 2007 Document with several Plain Text Format (I have tried Rich Text Format as well) controls which accept input via XML. For carriage returns, I had the string being passed through XML containing "\r\n" when I wanted a carriage return, but the word document ignored that and just kept wrapping things on the same line. I also tried replacing the \r\n with System.Environment.NewLine in my C# mapper, but that just put in \r\n anyway, which still didn't work. Note also that on the control itself I have set it to "Allow Carriage Returns (Multiple Paragrpahs)" in the control properties. This is the XML for the listMapper <Field id="32" name="32" fieldType="SimpleText"> <DataSelector path="/Data/DB/DebtProduct"> <InputField fieldType="" path="/Data/DB/Client/strClientFirm" link="" type=""/> <InputField fieldType="" path="strClientRefDebt" link="" type=""/> </DataSelector> <DataMapper formatString="{0} Account Number: {1}" name="SimpleListMapper" type=""> <MapperData> </MapperData> </DataMapper> </Field> Note that this is the listMapper C# where I actually map the list (notice where I try and append the system.environment.newline) namespace DocEngine.Core.DataMappers { public class CSimpleListMapper:CBaseDataMapper { public override void Fill(DocEngine.Core.Interfaces.Document.IControl control, CDataSelector dataSelector) { if (control != null && dataSelector != null) { ISimpleTextControl textControl = (ISimpleTextControl)control; IContent content = textControl.CreateContent(); CInputFieldCollection fileds = dataSelector.Read(Context); StringBuilder builder = new StringBuilder(); if (fileds != null) { foreach (List<string> lst in fileds) { if (CanMap(lst) == false) continue; if (builder.Length > 0 && lst[0].Length > 0) builder.Append(Environment.NewLine); if (string.IsNullOrEmpty(FormatString)) builder.Append(lst[0]); else builder.Append(string.Format(FormatString, lst.ToArray())); } content.Value = builder.ToString(); textControl.Content = content; applyRules(control, null); } } } } } Does anybody have any clue at all how I can get MS Word 2007 (docx) to quit ignoring my newline characters??

• Website Listing Commonly Used Ruby Gems, Including Alternatives

  - by ottobar

  I know that I've seen this site before, but cannot remember it for the life of me. Basically, it is a listing of commonly used gems, like XML parsing or ORM libraries.

I've googled and have not been able to find it.
