A HABTM B (to me) infers that the join table AB serves no purpose other than to link As and Bs. Without a specific A, the AB record has no meaning. So the HABTM specification lets Rails make the assumption that when A is deleted, the AB related to that A can be deleted as well. A has_many B A has_many C, through B implies (also to me) that joining through the intermediary table B is an artifact of the relationships between As, Bs, and Cs, and the entity modeled in B has value independent of its relationship between A and C. Like Project has_many :scenarios has_many :unittests, :through => :scenarios When a Project is deleted, I don't want all those Scenarios deleted... Unittest has_many :testings, :dependent => :destroy has_many :testresults, :through => :testings When a unittest is deleted, I delete all the testings (and testresults) since test results or testing instances aren't much use without the requirements (the unittest). -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

So you'll have to take control and write some code of your own. My own two cents... scaffolding is good for education, and a look at how Rails is designed to work, but it's just the basics. Never done Rails before? Scaffold up a model with some attributes, then go look at that generated code. Figure out how all the pieces and parts work together. Then start writing your own code. I use scaffolding for proof of concept all the time, but the scaffolded code doesn't survive very long at all. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Umm... no it won't, as evidenced by your own statement: > When i click on Goodbye link given in hello.html.erb file it says > "No route matches "/say/goodbye". Take a look at your log file and see what your Rails application is receiving when you click the "Goodbye" link in the browser. Review your routes.rb file. If you run a rake routes > routes.lst then look at the routes.lst file, you'll know exactly what routes you have available in your application. Next, re-read the Rails guide on routing.

But use the scaffolded elements as the prototype for your manual creations... If you have scaffolded something, then the "right way" (or at least the way that follows the Rails conventions most cleanly) is there in front of you. Suppose you want a book model. 1. You'll need a books_controller. By conventions: - the index method in the controller retrieves all the books into a variable named @books. - the show method retrieves a single existing book stored into a variable named @book according to an id received in the params - the new method created a new book, named @book via a simple @book = Book.new - the edit method also retrieves a single existing book stored into a variable named @book according to an id received in the params - the create method receives a book definition via params and creates a new @book instance from the values contained in the params, then attempts to persist that object in the DB. - the update method retrieves an existing book via a find using the id received in the params, then updates that books attributes with those also received in the params. - destroy finds a book according to the id received in the params, and, well, deletes it. Each of these controller methods, be default, will have its results rendered in a view named according to the method that the view supports. - index method renders its output via the index.html.erb - new and edit render via new.html.erb and edit.html.erb, each of which uses a partial named _form.html.erb (and yes, that underscore at the beginning of the filename is important). If you are creating your own, then don't forget to update the routes.rb when you add a new model and controller, or action to an existing model/controller. All of this is readily apparent from a study of a scaffolded solution, and a little reading. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you have an existing application, you can just add a scaffolded model, controller, and views via: rails g scaffold person first_name:string last_name:string (doesn't have to be person, could be anything, just give it a model name and some attributes with types).

Deserialize the string into the separate product objects (JSON.parse

Basically, children need to know their parents. Take a look in the log
at the queries generated, and you'll see items like:
Querying to show a recipe with id = 1:
SELECT 'directions'.* FROM 'directions' WHERE ('directions'.recipe_id =
1)
So:
Recipe (top of the food chain - haha)
# table has no _id fields
has_many :ingredients
has_many :directions
Ingredient
belongs_to :recipe # table must have recipe_id
has_one :measurement
Measurement
belongs_to :ingredient # table must have ingredient_id
Direction
belongs_to :recipe # table must have recipe_id
That should make your app happier.

Just correct either your controller, your model, your view code, or some combination thereof. Seriously, I don't think any specific help is available if you don't provide some information on how you tried to use it. If you have a control showing up empty, then it's missing its data. What's the source supposed to be? Does that plugin require code in the controller to provide the data? Or perhaps in the associated model?

Well, what you're trying to do in the top section would seem to indicate
that there isn't a size attribute available, or the method chaining is
getting scrambled. And the second filesystem example doesn't really say
anything about 'size' as you aren't interrogating the size attribute in
that code. All that aside...
Have you tried it in irb? And perhaps
Magick::Image.new( size => '100x100' )
(totally untested, and theoretical)

You aren't testing what you think you are...
.all returns an array even if it only finds a single instance, and at
last check, the Array class does not have a loaded? method.
Should your test be using some other method, perhaps empty?

What's your intended usage scenario? Depending on the resolution required from the CDF, could you just store built distributions in a table and query against it? With normalized inputs and the right indices, the query should be fast, and trading off record count versus accuracy, you could always do a linear interpolation between any two stored points. Need higher interpolated accuracy? Then increase the resolution of stored points to minimize the interpolated gap. Ugh...

Impossible.
You're defining author_yr in a ruby model, but expecting the DATABASE to
know what that is. Doesn't work that way.
As Fred mentioned, you need to use a database function that looks at the
"author_year" field (the last 4 characters) to order upon.
Look in the manuals for whatever DB engine you're using for string
functions. That's what goes in the :order => []

map.resources :tires
generates the 'standard' CRUD routing. There are two additional options
I'll mention (probably should have done it earlier)...
:collection and :member
:collection lets you define additional routes that work on a collection
of that resource
map.resources :tires, :collection => {:thumbnailed => :get}
would give you
<%= link_to "Thumbnails!", thumbnailed_tires_path %>
targeted at
def thumbnailed
# your method code here
end
in the tires controller, which by default expects a
thumbnailed.html.erb view file
:member lets you define additional routes that work on a specific
instance of the collection
map.resources :tires, :member => {:print_label => :get}
would give you a
<%= link_to "Print a Label", print_label_tire_path(tire) %>
targeted at
def print_label
# your method code here
end
in the tires controller, which by default expects a
print_label.html.erb view file.
You can add as many collection and member routes as you like in
routes.rb
This is all probably better explained at
http://api.rubyonrails.org/v2.3.8/classes/ActionController/Resources.html
around the middle of the page.
Remember to restart your server after changing the routes.rb

Given your code, "c" is an array (of Cardcid's) - and the Array class
does not have an address attribute.

Given this line, you are processing each individual element in "c" in a
variable named "cartcid"
> loc = MultiGeocoder.geocode(c.address)
Now you are referencing the array "c" again!!! Just like you were doing
in your earlier post. That line needs to be:
loc = MultiGeocoder.geocode(cartcid.address)

[Rails] Re: Newbe question
I think one of your key design decisions up front is who defines the tags/keywords? If it is left up to the users to enter tags, then you might look into the has_many_polymorphs gem and the tagging facilities available there. This case makes it a tad more difficult to deal with searches, because your users can enter tags willy-nilly, and you have to come up with some method of classifying them, ideally dealing with synonyms and misspellings. User-defined tags opens you up to some, er, inappropriate tags as well if your application is ever found out by the spam-spiders that crawl the web (a blacklist of tags to ignore would be your friend in this case I think). If you are defining the keywords, it becomes much more manageable, and you can classify the tags you support according to types... salary ranges, experience levels, locations, whatever. I usually include something like a code table in my apps, where I can setup a codetype (string), codevalue (int), and codetext (string) where I could enter things like below that can be used in droplists for selection of attributes. type, value, text: "salary", 1, "30-40k" "salary", 2, "40-50k" blah blah blah "experience", 1, "1-3 years" "experience", 2, "4-6 years" etc, etc -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

# has many stage standings (rider finish order)
# has attached images for the route
# map and the elevation profile

has_many :stagestandings
has_attached_file :map, :styles => {:thumb => '100x100>'}
has_attached_file :profile, :styles => {:thumb => '100x100>'}
end
<%= form_for @stage, :html => {:multipart => true} do |f| %>
blah blah blah, fields to select raceyear, enter the stage name,
description, terrain and distance, relevant image upload fields

<%= f.label :map %>
<%= f.file_field :map %>
<%= f.label :profile %>

Something is truly bizarre with this example you are trying
to follow... and I can't say that I fathom the intent of
the example in the tutorial. So I went to look, and found a
PDF about Rails at video2brain, but unfortunately, Ich spreche
kein Deutsches.
Strange issues with this example:
You generally don't POST to the index method... that's
usually a GET.
This code will always be modifying the first form due to the
Form.find(:first) statement... perhaps there is only supposed to
be one.
The detail model in params doesn't contain a form_id. You could
remedy that by:
@form = Form.find(:first)
@form.update_attributes(params[:form])
if @form.detail
@detail = @form.detail
else
@detail = Detail.new
end
@detail.form_id = @form.id
@detail.update_attributes(params[:detail])
That should at least get you a value for form_id in
the detail model (you did add form_id as integer to your
details table, no?))
But this example is "wrong" in so many ways. Finish it if you must,
then promptly forget this video2brain... gibberish.
Step up to Rails3, and find a couple of Rails 3 tutorials. You'll be
much better served spending your time on those.

Processing FactionsController#create (for 127.0.0.1 at 2010-09-23

[POST]
Parameters: {"commit"=>"Create",

"faction"=>{"name"=>"asdasd", "name_plural"=>"asdasd",

FactionContent Create (7.4ms) INSERT INTO `faction_contents`
(`created_at`, `updated_at`, `english`) VALUES('2010-09-23 19:46:39',
'2010-09-23 19:46:39', NULL)
no values for 'english' in any of the inserts
I think you're over-complicating things...
In factions_controller.rb:
def create
# just grab the hash for the model being saved
hash = params[:faction]
# do the string to content record id magic
hashnew = save_ids(hash)
# save a new Faction record
Faction.create(hashnew)
# find the one just saved
@faction = Faction.find(:last, :order => 'id')
end
And wherever you have this stored:
def save_ids(arguments)
# saving the content is table agnostic, don't need that parameter
# new empty hash to return
ret = Hash.new
# for the incoming arguments hash
arguments.each_pair { |key,value|
# store each value in Contents
Content.create(:english => value)
# find the record just written
content = Content.find(:last, :order => 'id')
# replace the string just stored with a stringified id from Contents
ret[key] = content.id.to_s
}
# return our new hash
return ret
end
worked for me...

I wonder if Authlogic overrode any of the default settings for BCrypt?
What do you get using irb for @version, @cost, @salt, @hash after:
@version, @cost, @salt, @hash = BCrypt::Password.new(u.crypted_password)
on your test user? Source docs indicate Password.new returns a

162: if valid_hash?(raw_hash)
163: self.replace(raw_hash)

Your posts 'smelled' a great deal like a total newbie post, and as such elicited a response directed at a total newbie. It may not have occurred to you that your spelling of user_loggin didn't strike Marnen (or I) as a "Say, he's a right smart bloke, and I bet he's not spelling the word correctly on purpose." type of posting... Right or wrong, there are tons and tons of ESL posts on this board that probably colored the response to your post. My initial thought was "Oh crap, another person trying to code php in Rails..." Your subsequent comment that "and it messes with URL routing or some thing ..." in your second post also sent up red flags for me that 'Why this bloke seems to have no clue what he's talking about." >From your fourth post: "Why would I use restful if I have no clue how to use restful?" Umm... perhaps because long-time readers and posters on the forum assume that you come to this forum to learn from people who have already traveled the road you seem to be on... perhaps because restful routes is a big thing in Rails, which happens to prefer convention over configuration, and you seem to be thinking configuration, so perhaps a redirect was in order... A great place for information is api.rubyonrails.org; another great place is your own machine in the console window, and your development log. Look in the dev log to see what the parameters are that your app is receiving. Read the api (particularly the routing part) to better understand that piece. When you used scaffold, did you just scaffold the full deal (something like: script/generate scaffold person last_name:string first_name:string ). That'll generate the controller, model, views, routing - rake that migration then play with that basic app - read through the generated code to learn how it all fits - it is amazingly educational about the Rails conventions. Generally, if it is hard to do, you're doing it wrong. Simple as that. I don't always agree with Marnen's opinions, and he does tend to state things a bit strongly for my taste, but I do always read his posts. Why? Because he knows more than I, and a hell of a lot more than you. But as your later posts have indicated, you are not interested in learning from anyone more knowledgeable than you in Ruby and Rails, you just want an answer to your 'user_loggin' question so you can write the code your way, however against the conventions of Ruby and/or Rails it might be. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You should start with a basic tutorial somewhere and follow it, trying to understand how it all fits. My favorite way to get people started is to tell them to scaffold a basic application, then see what the generator created, and understand how it works. Later, worry about an admin, or namespacing. script/generate scaffold person last_name:string first_name:string (that creates an initial db migration, controller, and views for a person) rake db:migrate (create the table) script/server Now browse to your app, and add a person or two, noting which link you clicked to do what.

No, that's not correct. Unless you updated your routes.rb file and restarted your server, you don't have a 'show_admin' routing.

The selected value is in params already, just not where you're looking.
Take a look in your log at the post request that rails receives when you
submit the form... this information is all readily available there.
You should see something like:
Parameters: {"utf8"=>"blah1", "authenticity_token"=>"blah2",
"model_to_populate"=>{"column_to_populate"=>"blah3",...},
"commit"=>"blah4", "id"=>"blah5"}
In your controller code,
params[:id] is the id of the 'model_to_populate' (blah5)
params[:model_to_populate][:column_to_populate] is the value stored by
the collection_select statement in the view (blah3)
Parsing through and understanding your log files is something everyone
should be comfortable with. It's usually the first stop in performing
triage on unexpected behaviors.

Related to model-based cache expiration, in one large-ish Rails project, the sidebar for a 'show' of an entity contains a view of all the related entities in the application. We were getting hammered on both db access and rendering time, so I implemented fragment caching in a multi-tiered approach, and left it to the models to expire caches of their data -- a fine line to walk, but that worked the best for us.
