You could convert the string to a time object and pick out the

the time in the database at some point.

[Rails] Re: Implementing a News Feed / Activity Feed on Several Models - Recommendations?
Nice solution!
Another possibility would be to use the before_create and delete
methods.
Or just have the new controller pull the latest info from your other
models by looking at the updated_at field. This way you wouldn't have
to have an extra step when deleting items.

I did it by creating a new model called FeedItem and then creating an
observer to watch a certain subset of models and create feed items
when they were created, updated, and deleted. FeedItems have a
polymorphic association to the model being talked about and a user
association for who is doing the action, and then a string field
denoting the action taken on them (created or destroyed for
example).
Then on each model I created a #best_identifier method which allows
the model to specify how it should be identified to the user in the
feed and elsewhere in the app. So for the feed itself, I just render
the last 30 feed items with #{feed_item.user_id}
#{feed_item.action_name} #{feed_item.modified_model.best_identifier}
on #{feed_item.created_at.to_s(:short)}.
Hopefully this helps! I can pastie my exact code if you'd like. There
are some other small tidbits to add like checking for destroyed models

[Rails] Re: Paperclip - helppppp
If you're getting the original image then you have ImageMagic setup
correctly.
On Windows there is a bug in the current paperclip gem where the
ImageMagick arguments are surrounded by single quotes, which windows
doesn't like.
Take a look at the console output to see the errors, try the commands
that paperclip log outputs. If you have the single quote problem then
update the paperclip.rb file:
def quote_command_options(*options)
options.map do |option|
option.split(').map{|m| #{m} }.join(\\') #removed single
quotes around #{m}
end
Also note that in current version of ImageMagic the size in the styles
hash no longer takes a final character, only the dimensions. So if you
have :medium ='300x300', it now has to be just '300x300'
Hope this helps

Example: Models Person has_many :scores Contest has_many :scores Score belongs_to :person, :contest Routes resources :people do resources :scores end resources :competitions do resources :scores end I want to be able to list scores by person, or by competition. Either of the these two paths will request the :index action in the :scores controller: GET /people/person_id/scores GET /contests/contest_id/scores So what is the best way to structure scores/index to deliver the appropriate list? I could test for the presence of params[person_id] or params[contest_id], then execute and render accordingly within the :index action. But that seems somewhat inelegant. Does it? If you want to reuse the same controller action, it seems entirely reasonable to test the data you're getting passed. Is there a better way? Should I have two separate actions within the :score controller, and modify my route mapping somehow to request the appropriate action? You could do that, certainly.

[Rails] Re: Trying to pick a model setup without ridiculous routes
Finally - a subject near and dear to my heart - beer! One thing to remember about nested resources is its best to nest one level at a time. Otherwise you get very complicated url's. Depending on how you set the relations, you could have beer as a nested resource of brewery and then set a separate nested resource relationship between beer and style. map.resources :beers map.resources :breweries map.resources :styles map.resources :breweries, :has_many = [ :beers ] map.resources :beers, :has_many = [ :styles ] So when you are dealing with breweries, you are only dealing with beers. The same thing happens when you are working with beers, except now you have the styles sub-resource. Looking at this problem though it seems like a better solution would be a has_and_belongs_to_many relationship between beers,breweries, and styles. A brewery can make several different beers each of a different style after all. To do this you would create a join table that only includes key fields (beers_id, breweries_id, styles_id).

I use Delphi (Lazarus) at work and I constantly miss ruby features :) I can only echo Marnen's remarks about Rails, Delphi does some weird things and I've found that doing it the Rails way is usually simpler and much more efficient. As far as the bookings, you should do a bottom up review by starting off with what would be the perfect view for you. Something by venue that not only shows the two teams but their win/loss percentage and amount of late/early games which would aid in scheduling. Make something that makes sense to you. Clashes though - shouldn't that be the player's responsibility? Also, don't forget unit tests and a revision control system (like git) as both of these will help you in many ways.

In the case of the game draw, there may be previous games played and the draw is a redraw for part of the season due to the addition or removal/transfer of teams. I need to ensure that the teams (up to 16 teams) have not played each other for the longest time. Its a matter of testing each future week in the draw template to find the best week to start. In the case of court game time bookings, I need to ensure that neither team has been booked at the time and court combo being tested for the longest time. The teams will complain that another team has had x early games while they have had x late games. Further, the system must support clash teams where a team playing volleyball will not want to booked at the same time as a team playing basketball if some players play in both teams. Teams may also have times when they can't turn up to play. My customers are commercial social sports centers with potentially fluid competitions as teams may come and go during a season or there may be team regrades after several weeks if a team is either much better or worse than the other teams in its league.

[Rails] Re: Rails equivalent of Delphi SetRange()
There are a few ways to do this.
One would be using a named_scope in Rails 2 or just plain scope in
Rails 3
class Bookings ActiveRecord::Base
named_scope :discount, :conditions = { :discount .5 }
I like to model class methods for pulling specific information from
the database
def self.inactive
find( :all, :conditions = [inactive = ?, 1], :order
= :last_calibrated_on )
end
And then in the controller:
@inactive = Item,inactive
In Rails 3 there is a new query interface (
http://m.onkey.org/2010/1/22/active-record-query-interface )
The neat thing here is that it seems to map well to what you're doing.
You start off creating a relation that you can then manipulate, but
the query doesn't fire until you want it too.
Getting those datasets or updating the limits could be done through
javascript on the view page, periodically_call_remote or an observer
on a field.

My app frequently issues the setrange command to a dataset in a loop in

Is there any way I can do this in Rails or do I need to repeatedly make

the query would only be run after calling the index action.
cars = Car.scoped
rich_ppls_cars = cars.order('cars.price DESC').limit(10)
It appears that the call to cars fires the query but the call to
rich_ppls_cars only works on the resultant dataset and does not fire a
new query. Would that be correct? For example, I could then say
poor_ppls_cars = cars.order('cars.price ASC').limit(10) and I would get
different data without a new query?
In Rails 3 the cars example above, you are creating a relation. The
query is fired when you call rich_people_cars.first or .all
Looking at some of the other posts here I agree there could be some
misunderstanding of what you're trying to do.
If it's 16 teams * 16 games that's only 256 results. You can query all
the records and then logically view the remainder in instance
variables.
Also, if you're looking at the bookings for holes then perhaps you set
the query to return records based on the date and venue. There are
only so many dates and venues available after all.
Interesting problem though and a good way to learn Rails.

Every book is likely to contain some errors, most will have forums where you can ask questions of the subject material as well. Netbeans has everything I need. The side panes which show the project structure and page elements which make not only navigating, but understanding, the project easier.

What do you have in your by_company method?
looks like you had in your find statement - params[:id] and it should
have been params[:company_id]
You might take a look at generating a class method in your model file:
def self.by_company( anId )
find(:all, :conditions = [company_id = ?, anId] )
end
The you can refer to this by Model_name.by_company( x )
Or a named scope - some things to look at.
Hope this helps

The web server simply looks at the information you submit ( a page for example) and routes it to the proper destination in rails. With me it's frequently error pages though. Rails comes with a web server named webrick which works nicely enough for learning about Rails. Mongrel is a separate, higher performance web server that you can install via gem.

[Rails] Re: Model Namespace?
You could add a status field to your higher level models - for example, add 'status' to User as an integer and then store your status:descriptions in a common status table. So you store an integer referring to the status in your User model and if you need to display the description, query the status table with the id. Or you could create the status tables and setup the relation between them - both sides - the User would have_one = :user_status and the belongs_to in the user_status model file. I don't know if I would put the status views below Users or Projects though. Depending on how many controllers you have - if it's a lot then try to put the status under the User or Project views. It's more than likely they should be beside the other controllers as you will probably be adding some functionality to the status controllers such as notifying someone if a project is in X status for some amount of time. Also I would think the status controllers would be easier to reuse if kept higher in the hierarchy. In any case, you can put links to change the status anywhere you like. Simply Rails 2 contains some very good examples of this using javascript. You might want to check it out.

[Rails] Re: Controllers, what? why?
I'm writing an application to track calibrated assets. If I were to have one controller it would have to be able to update(delete, create, read) the items,vendors, issues...etc. It would be huge and certainly unwieldy, not to mention very difficult to do in the Rails framework. The Items controller deals with the items table. All the views to the data happens through this controller which makes the code easy to read and understand.

[Rails] Re: Why do rails calls a method when I'm calling a property?
Look at your link_to in the index.html, it should contain the id for the story you want to show. Also, check to make sure that you have the to_param method in your model, story.db and that it's correct. The author implements a complicated beautification of the urls which is a waste in the course of the examples. I have the same book, one of the best for learning rails imho. One other question for you - there are some extra methods that are a bit confusing, your bin method and the get_stories for example. I don't think the saving of a few lines of code is worth the possible confusion.

[Rails] form_remote_tag running only once
I'm trying to add a simple search to an index page of my project. It
takes a term, does a 'like' query and populates a common partial which
is displayed with javascript in the div 'search_remote'.
It runs fine, once. If you run multiple queries without hiding the
div, it works fine. If you close the div and attempt to search again
you get nothing. The console shows that the controller method is
firing but the div isn't getting updated.
In the view:
% form_remote_tag :update= search_remote,:url = { :action =
search_remote } do %
%= 'Search for Description:' %
%= text_field description, description %
%= submit_tag 'find' %
% end %
div id=search_remote
/div
In the controller:
def search_remote
if params[:description]
search_term = params[:description][:description]
search_term = '%' + search_term + '%'
@search_results = Item.find(:all, :conditions = [description
LIKE ?, search_term])
render :partial = search_remote, :locals = {:aGroup =
@search_results, :show_hide = 1, :aToken= 'search_remote'}
In the partial _search_remote:
%= link_to_remote 'hide',
:update = 'search_remote',
:url = {:action = search_remote, :token = 'search_remote' },
:complete = visual_effect( :blind_up, 'search_remote', :duration =
0.2 )

One other way to think about this - you shouldn't need to nest resources more then one level deep. You only deal with children in relation to parents and dogs in relation to children.

[Rails] Re: REPL in a browser.
If just want to process some basic commands in a web environment you could create a form which simply re-displays itself. Setup a class variable (or simply use the flash notification) to hold the result of whatever you want to do and instead of redirecting to show or index, redirect to new. Then display it in your view. You can assign a blank value for the first run. A simple model could hold the previous entries and you could iterate over this in the view if you wanted to show history. One word of caution though, make sure you have a good grasp on the security implications before you expose your computer in this fashion.

So even if someone could just point me in the right direction, I'd appreciate it. * FYI, I am trying to create an online version of my research project: an interpreter and interactive environment for a small functional language. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: Complicated polymorphic relation
First, try not to worry so much about how the tables are set up, you can create a view to the data to suit your needs. What you need to be concerned about is how to make the information easy to use and to not repeat yourself. As to modeling the data - It seems that the User table would be the central piece and he or she would have one mandate or perhaps more? Either has_one or has_many. It would also seem the user has a location as well as mandate. Another one to one relationship here and again, the user may have more then one location - has_one or has_many Model User id name etc. Has_one: mandate has_one: location Model Mandate id user_id etc. belongs_to :user Model Location id user_id etc. belongs_to :user Then you could have a look up table for the types of mandates and locations. Hope this helps On Jun 28, 12:48 pm, Adrien Coquio adrien.coq...@gmail.com wrote: this solution doesn't fit with my project i have to explain : the table MANDATES contain the list of possible mandates like : (0,mayor,city) (1,deputy mayor,city) (2,minister,state) (3,king,state) this list use by me to make a form where the user of my program can select the mandate related by user the table ELECTED contain the relation between user and mandate like : (0,John Smith,mayor,Chicago) (1,Brad X,mayor,New York) (2,Adrien Y,king,Brasil) (3,Anton Z,minister,Great Britain) NB: i replace user_id,mandate_id,place_id by user.name, mandate.name,place.name the solution which i see to do that are : 1)i have explain in the first post 2) duplicate the field place_type in the table ELECTED (maybe it is the easier solution?) 3) group tables MANDATES and ELECTED like that : MANDATES - id - name - place_id - place_type - user_id in that way i create all possible mandates with no user related to make the form and when i have a relation between user/mandate i create a copy of the mandate with the user_id what do you think about this solution? thanks adrien On Jun 28, 5:12 pm, Marnen Laibow-Koser rails-mailing-l...@andreas- s.net wrote: Adrien Nom wrote: I want to do that way because i must save the possible mandates in one table. That's not a good rationale. The place_id is part of the mandate just as much as the olace_type is, so it belongs in the mandates table. Then i use an other table to save the relation between mandates and users. How can i do that with an other way ? If I understand you correctly, this will be very easy with your current schema, once you make the change I am proposing. Basically, place_id is a property of the mandate, so it belongs in the mandates table. Since you have mandate_id in elected, you can get the place_id with something like @elected.mandate.place_id. thanks for your answer adrien Best, -- Marnen Laibow-Koserhttp://www.marnen.org mar...@marnen.org -- Posted viahttp://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

It seems like the two controllers could be combined.

[Rails] Re: How do i model this in Rails? (put down java equivalent design)
Does seem to be a bit of repetition in your description but it seems straightforward. You have a Module which has an Entity_type column Each Module has many Chapters where Chapters has a column named module_id. Each Chapter has many Activities with similar foreign key constraints or You have one Activities table, in which case you don't specify a relationship. Once you set up the has_many and belongs_to pairs, Rails provides the methods to interact with the data. Checkout some ActiveRecord tutorials like this screencast - http://www.railsenvy.com/2007/8/8/activerecord-tutorial On Jun 6, 10:29 pm, Ritvvij ritvi...@gmail.com wrote: Hello guys, Need help!! Finding it hard to model the 'model' :P within the given rails associations. In java terms, my requirements are... There are 3 entities - module, chapter and activity. Chapter entity is a specilization of Module entity (inheritence) Activity entity is a specialization of Module entity (inheritence) And the tables would have looked like: 1. Module table = Module_Id, Entity_type, 2. Chapter = Chapter_id, . 3. Activity = Activity_id, .. Hence, if I create a chapter then the tables would be populated as: Module table = Module_Id, Entity_type, = values ( 100, chapter , ) Chapter table = chapter_id, . = values ( 100, ) Basically, the ids of chapter and module would be same and module table would store the type. Now, if I create a activity then the tables would be populated as: Module table = Module_Id, Entity_type, = values ( 101, activity , ) Activity table = activity_id, . = values ( 100, ) Basically, the ids of activity and module would be same and module table would store the type. Can you please guide me how I can model it similarly in rails 2.3.2?

[Rails] Re: can't get a simple partial to work !...@#!$!!
Perhaps you should look at the whole of DHH wrote. It is perhaps something like: render :partial = 'test' or has a :test = @var clause to give the test variable. The code you posted doesn't contain any variable named test, otherwise you wouldn't get the error in the first place. If you want the code to work, replace 'test' in the index view with '@array' On May 10, 1:35 am, 7stud -- rails-mailing-l...@andreas-s.net wrote: AGoofin wrote: When you render a partial you automagically get an object with the same name available in the partial For example, render :partial = 'foo' passes the instance variable named @foo to the partial where I can then say: for f in @foo. How do you know that @foo isn't already available to all the views and that writing render(:partial = foo) doesn't have any effect whatsoever on whether @foo is available in the partial? In your first post you iterate over 'test' but that variable isn't created anywhere. Sure it is. Try it. I'm just a beginner but my Dave Heinemeier Hansson book says the variable test gets created by the render() statement, and my tests confirm that's the way it works. More generally, when I write % render(:partial = random_name, :object = @var) % and @var was assigned a value in the controller, then I find that the value of @var gets assigned to the variable random name, and random_name can be accessed in the partial _random_name.html.erb. In addition, my tests show that @var can be accessed in _random_name.html.erb as well. I'm not sure why you would want to stuff the value of @var into another variable when you can just access @var directly. Switching the names seems confusing to me. -- Posted viahttp://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: can't get a simple partial to work !...@#!$!!
When you render a partial you automagically get an object with the same name available in the partial For example, render :partial = 'foo' passes the instance variable named @foo to the partial where I can then say: for f in @foo. In your first post you iterate over 'test' but that variable isn't created anywhere. Using: for a in @array might work providing that the partial is part of that controller though. Or rename @array to @test. I don't know how many times I have stopped and looked for the painfully obvious - like with RESTful resources - the key is to make that part of the trouble shooting.

[Rails] Re: referential integrity
Your Team has many members and should be noted: class Team ActiveRecord::Base has_many :members end This is assuming that you have a column in your member table named team_id. I think this is what you were asking about with the foreign keys. As a somewhat noob to Rails myself I found a few good books for beginners to be the most help. The two I like the best are: Simply Rails 2 and Agile Web Development with Rails.
