[Rails] erb_variable and migrating old rails app 2.0.2 -- 2.1 --.

[Daniel Bush]

Hi,
I'm migrating an old rails app from 2.0* to 2.3 and eventually 3.  I
thought I'd start with 2.1.* so as to progressively fix any issues that
cropped up.

Unfortunately both 2.1.2 and 2.1.1 fail to run my unit tests and
complain with the following message:

{:erb_variable==The erb variable will no longer be configurable. Use
the concat helper method instead of appending to it directly.} is not a
symbol

The changelog for 2.1.1 has: Deprecate ActionView::Base.erb_variable.
Use the concat helper method instead of appending to it directly.
[Jeremy Kemper] 

2.1.0 works ok.

So it seems that there is something that is trying to use erb in a
deprecated way - and presumably it is not in the framework itself but in
my rails app and possibly any gems it is loading.  Trouble is I'm having
no luck wading through the stack trace (rake test:units --trace).
Everything in the trace is either the framework itself or 3 other gems:
rake, rubygems and deprecated.
There is only one reference to my rails app, specifically to the line in
my environment.rb file that runs
   Rails::Initializer.run do |config| ...

Anyone have some sage advice on upgrading rails and locating/pinpointing
strange issues like the one with erb?

Regards,
Daniel Bush

[Rails] SOLVED Re: erb_variable and migrating old rails app 2.0.2 -- 2.1 --.

[Daniel Bush]

The problem was the version of the deprecated gem I was using and not 
erb or any of my rails code.
Rails 2.1.1+ works find with deprecated-3.0.0.  I had an older version 
which was blowing up in 2.1.1+.

Because the Examples and Questions are has_many Sections, they are also

to a given tutorial instance.

Anyway, it seemed like the Section abstraction was a nice way to show off

[Rails] Re: help active record modeling.

[Daniel Bush]

2009/4/29 serenobs seren...@gmail.com


 Hi.

 I have difficulties to model active record.
 So please help my trouble.

 Let's suppose there are nations which have castles at least 1,
 and there are 3 types of castles.

 So I will make these tables.
 NationsTable,
 CastlesTable have common attributes of 3 types of castle.
CastlesATable, CastlesBTable, CastlesCTable each have its unique
 attributes.


Easier to call your tables: 'nations' for 'Nation' model and 'castles' for
'Castle' model ... etc



 In this case how can I represent this DB to AR?
 I think
 class Nation  ActiveRecord::Base
   has_many :castles
 end
 class Castle  ActiveRecord::Base
  belongs_to :Nations
 end


Using the naming convention I suggested above you'd say:
 belongs_to :nation

After all, a castle can only belong to one nation at a time right?


 but I'm not sure of what will be coded to these models.

 class CastleA  ActiveRecord::Base
 end
 class CastleB  ActiveRecord::Base
 end
 class CastleB  ActiveRecord::Base
 end

 please help me.


You could use single table inheritance (STI).
1)  all castles are stored in one table ('castles') which has all the
required attributes for all types of castles.
2) in app/models you'll have your Castle model and then you'll have a
CastleA,B and C models like above but you now inherit from Castle:
class CastleA  Castle
end
3) You include a 'type' field in 'castles' table which is a string and is
the same as the class name  of the castle. (ie for an A-type it would be
'CastleA')

This is a tidy way to handle your castles as everything is in one table.  It
does mean that not all attributes will be used by a given castle instance if
you have specialised attributes; these will probably be null so I don't
think the wastage will be much.



 and second question is
 when nation deleted, CastleA, CastleB have to be deleted but not for
 the castleC type.
 how can I do?


I'm never good at this stuff.  But you could do it with a callback in your
Nation model:

class Nation  ActiveRecord::Base
  has_many :castles
  before_destroy do |nation|
Castle.destroy_all nation_id=#{nation.id} and type!='#{CastleC}'
  end
end

There's probably a sexier way to do that.

[Rails] Re: Polymorphic Associations... confusing. Do I need them?

[Daniel Bush]

2009/4/29 Chris Hanks rails-mailing-l...@andreas-s.net


 Sorry, no, I'm looking for questions and examples to each belong_to one
 tutorial, and a given tutorial has_many examples and has_many questions.
 What I'm really looking for is a way to refer to questions and examples
 together in certain situations.

 I'm wondering if I can do something like this (crazy fantasy code):

 class Tutorial  ActiveRecord::Base
   has_many :questions, :as = :sections
   has_many :examples, :as = :sections
 end

 That way, questions and examples could be represented as different
 sections of a tutorial. Then, when I want to display a table of contents
 for a tutorial, I could write:

 % for section in @sections do %
   %= section.title %
 % end %

 And get:
 (an example title)
 (a question title)
 (an example title)
 (an example title)
 (a question title)
 (a question title)
 (an example title)
 ...

 In the order they appear. I'd also need a position attribute on the
 sections for each tutorial, also, to make sure they appear in the right
 order.

 Does that make sense? I think single table inheritance might do this,
 but I'm planning on using examples and questions for a bunch of other
 things, so I don't think it would work that well. I'm thinking about
 defining a whole new section model, and using that, but I don't know
 yet.



You could define a Section model which belongs_to your Tutorial model and
has a position attribute so you can determine the order.

In your Tutorial model
has_many :sections ,  :order = 'sections.position ASC'

You then set up your Example and Question models so that they have a
polymorphic has_many association with the Section model.

In Section:
belongs_to :sectionable , :polymorphic = true

In Question or Example:
has_many :sections , :as = :sectionable

Now you can say:

@tutorial.sections.each do |section|
  section=section.sectionable
  case section
  when Example
puts section.some_example_method
  when Question
puts section.some_question_method
  else
puts 'what!'
  end
end


Has the nice benefit that you can recycle your examples and questions in
next year's tutorial if you're lazy  :)

[Rails] Re: Rails and Sphinx

[Daniel Bush]

2009/4/16 fausto fausto.ga...@email.it


 Hi, i'm currently using ferret+acts_as_ferret for doing some searches
 in the db (not so big for now, just 40k~ records, but they will be
 near 2M+ soon). For now ferret it's working quite well, but sometimes
 i've indexes corrupted (i use it's drb server in production) and i've
 to rebuild all the indexes, so i've bad indexes, angry users and time
 spent to make it right.
 I'm looking at sphinx and it seems the answers to this problems, as it
 seems that it doesn't have this such of problems. But i've seen that
 i've to remake indexes everytime (/hour or less).. does it take a lot
 to rebuild them?
 Is there anyone who use shpinx in production?
 Another big question about it is if it's possible to create custom
 indexes without having the records in the db,


You can send an xml docset document to sphinx to build the index; use the
xmlpipe2 source type in your conf and have a script that will generate the
xml to STDOUT.
The docset contains a set of documents with id's (which you might map to the
id in a table in your database if you were using it). Each document contains
a set of field tags with the information you want to index.
I don't know how that squares with large datasets - my app was very small.
I use the Riddle client that comes with Thinking Sphinx to talk to searchd.

Some of this stuff is documented on the sphinx website somewhere, though
piecing it altogether took some effort.

[Rails] Re: What does the ' %s ' mean ?

[Daniel Bush]

2009/4/9 Tom Ha rails-mailing-l...@andreas-s.net


 Hi there,

 can anyone explain to me how I have to understand the:

  %s

 in the following code line:

  yield :error, There was a problem resending your activation code,
 please try again or %s., resend_activation_path

 Whant does it stand for, what does it mean, what does it do?


I'm not familiar with that particular bit of code, but I think this relates
to the % method for String classes in ruby.  See
http://www.ruby-doc.org/core/classes/String.html#M000785 .

This is ruby's way of doing format control letters and modifiers.  If you've
programmed in C etc or something like awk, you often use these in print
statements (eg printf) to format strings and numbers etc.
Whenever I have to look these up I check out the gawk reference - here's one
online:
http://www.gnu.org/software/gawk/manual/gawk.html#Control-Letters

Simple example in ruby:

foo%s % bar
= foobar

foo%05d % 1
= foo1

2009/4/9 Phlip phlip2...@gmail.com


  div id=%= post.title % style=display: none;

  Just make sure that %= post.title % is unique for the page.

 An id must conform to roughly the same rules as a JavaScript identifier. No
 leading numbers, no spaces, no funny business. Of course no browser bothers
 to
 enforce that, but such rules exist to help us Rails programmers write
 rigorous
 code that goes far beyond browser forgiveness.

 div id=post_%= post.id % style=display: none;

 Just to complicate things, it was recommended in the past not to use
underscores for id and class names because of the css specs.
http://devedge-temp.mozilla.org/viewsource/2001/css-underscores/
I don't think it's a problem these days but I started to hyphenate in place
of underscoring because I noticed my syntax highlighter didn't like
underscores which led me to this whole weird issue.

[Rails] Re: Displaying 'ticked' check boxes

[Daniel Bush]

2009/4/7 Helen Smith rails-mailing-l...@andreas-s.net


 I need to display check boxes as 'ticked' in my edit function where
 there is a corresponding value for them in the database.

 In my new function a user can select between 1 and 4 tick boxes and I
 need these ticked check boxes displayed back to them when they go in to
 the edit function for that database item.

 Most appreciated if anyone out there can help please?

 from the check boxes - so I just need to display these as 'ticked' in my
 edit function.

Hi Helen,
Had a bit of trouble reading the last section.
To check a checkbox, you have to say:
  input type=checkbox ... checked=checked /
The value attribute can be whatever you set it, but maybe use the rails
default which is 0 and 1 for not-ticked and ticked respectively.  Bear in
mind that the html spec says that if you don't tick the box, it won't get
sent back to the server so other things being equal, your server won't get
to see 0.

You should read
http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html as a
starting point for what rails can do to help you build forms and in
particular check out the 'check_box' function which employs a little hack to
get round the html spec so that you do see '0'.

Ideally, you want something a little like this:
% form_for :transfer do |f| %
...
%= f.checkbox 'agreement_1' %
...
% end %
I'm assuming you have a @transfer model or object which is created in your
controller action with an 'agreement_1' method that returns a boolean or
something like that.

You can of course create the checkbox manually, but you'll need to write
code to test the boolean and insert the checked attribute/value pair into
your tag:
  %
  checked=i
  checked = %{checked=checked} if agreement_1
  %
  input ... %=checked% /

 How can I convert diff now into minutes?

What class is my_date ? (my_date.class)
Is it DateTime, or is TIme or ActiveSupport::TimeWithZone ?
In general, the difference seems to be in seconds when you subtract
two objects of the same class so you'd divide by 60 to get minutes.  I
think you can also subtract between Time and TimeWithZone but you may
run into trouble with other combinations.

This appears to be a 'show' action - not 'search'.
I'd say that your GET-request for /streams/search?search=... is being
mapped to your 'show' action - see last comment below.


 corresonding url have like:
 http://localhost:3000/streams/search?search=352x240

 so can any one help me out in this issue.

 1)in controller added search method like:

 added for search option
   def search
 search_criteria = Article.find_tagged_with(params[:search])
  if search_criteria.empty?
flash[:notice] = Please enter search criteria
@searchresults = 
  else
@searchresults = Streams.find
 (:all, :conditions=search_critera)

Even though the error was in 'show', there look to be some errors here
in 'search'.

I think Article.find_tagged_with will return an array of Article
models.  You haven't mentioned your Article model - you seem to have a
Stream model (which you should use in the singular not plural).  So
maybe you mean Stream.  You then use this for the :conditions clause
in Streams.find(...) which is probably not going to work
because :conditions corresponds to a WHERE-clause in sql.  Check the
docs for the 'find' method (api.rubyonrails.org).

  end
respond_to do |format|
format.html # show.html.erb
format.xml  { render :xml = @stream }
  end
   end
 

 2)and in view/streams/index.html.erb file

 % form_tag(search_streams_path(), :method = :get) do %
  %= label(:search, :tag, Search:) %br /
  input name=search id=tag type=text size=17 value='%=
 session[:search_keys] %' style=width:123px; /
  input type=image id=bt_zoek src=/images/search.jpg
 alt=search style=border:none;/
 % end %

 3)in routes.rb added line;

   map.resources :streams, :collection = {:search=:get}

Just a guess: but did you add ':collection' to
map.resources :streams after setting up this resource? If you did
and you didn't reload the routing table (restart you app), then the
search action won't take effect and your show action might be used
instead which might be why you get the error in 'show' with id being
mapped to 'search'.

 Posted viahttp://www.ruby-forum.com/.

You can name your files like:  shopping_cart_item.rb but define the
class inside as 'ShoppingCartItem'.  Similarly for shopping_cart.rb
and class ShoppingCart.
Glad it helped.

[Rails] Re: creating array of hashes

[Daniel Bush]

Hi - see below...

...
 I need to have the array of hashes as
 [{employee_record1},{employee_record2}.. n records]

 For this i tried as the...


 result = []

 for employee in Employees
 res = {}
 for field in fields

You used 'Fields' above instead of 'fields' here.

   res  { field = employee.send(field)}

res[field] = employee.send(field)

'res' is a hash.  You build it by setting key/value pairs not pushing
onto a sequential array.
That should probably do it.

Some other things that might be of interest:
   employee.attributes
will give you a hash of all the fields and their values for an
employee object but you might only be wanting a subset.  (You could
'delete' them.)
   Employee.column_names
will give you an array of all the column names.


end
 result  res
 end
 But it is not working...

 Finally i have to replace the 'result' with the PDF::SimpleTable.data
 through the statement

 = table.data.replace result

 which accepts only the hashes... whose columns are the keys and the column
 data as values


  Please Help me Thank You

   Hi!

   I'm struggling with this for a while and i'm new to rails so it's
   quite frustrating ;)

   I need to create new model object based on old one with only few
   changes.

   I have desings - has many - lines - has_many - fields

   I've got input from user in array like this:

   field =[
       line_id =[ fiel_id = field_value]
   ]

   so I iterate:

   input[:field].each do |line_id, line|
       line.each do |field_id, field_value|
       design.lines.find(line_id).fields.find(field_id).value =
   field_value
       design.lines.find(line_id).fields.find(field_id).something =
   field_value
   end
   end

  You're finding stuff and assigning new values to what was found but
  not saving these changes back to the db as far as I can tell here.
  Retrieve the field once
    field=design.lines.find(line_id).fields.find(field_id)
  update its values and then save it
    field.something = ...
    field.save (or field.save!)
  You're not creating anything new, just updating old.

  If you want a new field, you'll need to create it:
    design.lines.find(line_id).fields.push(Field.new({hash-of-
  attributes}))
  This will add a new field to design's line with line_id.

  You could probably do something like
    new_field=Field.new(field.attributes)
  to create a new field with the same attributes as the existing
  'field', alter
  its values as required and then push it onto the fields collection:
    design.lines.find(line_id).fields.push(Field.new(new_field))

  Be careful with names like 'field' - I don't know if they'll clash
  with rails names.
  Maybe also consider not chaining all those 'finds' together in one
  line.
  Find each thing and store it in a local variable or an instance
  variable so
  you won't have to get it again during the action.

 I followed your suggestion and write this code:

 1    new_design = Design.new design.attributes

There's actually a 'clone' method which is probably better than what I
suggested before.
  new_design = design.clone
But don't forget that you'll need to save it at some point.

 2   design.background.colour_id = 123
 3    new_design.background = Background.new
 design.background.attributes
 4    lines = design.lines
 5    for line in  lines
 6        new_line = Line.new line.attributes
 7        fields = line.fields
 8        for field in fields
 9          field.value = input_data[:field][line.id][field.id]
 10          new_field = Field.new field.attributes
 11         new_line.fields.push(new_field)
 12        end
 13       new_design.lines.push(new_line)
 14    end

    and now I'v got error that i have nil object in line 5, 8, 9 so it'
 seems that rails think's design has no lines.


I'm guessing it's line 9 and it has something to do with input_data
[:field] or input_data[:field][line.id] that's returning nil.  5 and 8
are just part of the looping which means there are lines and each line
does have fields.

You could compress your code a little eg
  design.lines.each do |line|
new_line = line.clone
...
line.fields.each do |field|
...
end
  end
I didn't mean to break everything up into separate assignments;
whatever you think is best.

Calling attributes[email] would trigger the above conversion error
because arrays expect numeric indexes.

Also, I noticed you're saying :id = @contact . I would have though
@contact.id but might be missing something.

Sorry.  Wasn't familiar with it.  Hard to imagine rails putting in a

Can only surmise that

I don't think any order is guaranteed either unless you've
specified :order somewhere so it may change randomly depending on your
database.  Maybe you added a new proposal with no proposal versions in
addition to proposal with id=1.  Or a new document even.

Once you do get on the horse, you can then follow the changelogs

 one suggestion:  don't put business logic in your views.  replace

  Now this works perfectly when _adding_ FlightTimes as I'm using a

  edit the values. When I try to use this form for editing, all the
  values in the boxes are emptied and anything I put in them are added
  as new FlightTimes (obviously). There can only be one FlightTime per
  FlightType per Flight, so to speak.


As per jemminger, if you want your action and template to both create
new objects and edit existing ones you need to put this logic into the
action in the controller.

So you might have:
  if params[:id]
@foo=Foo.find(params[:id])
  else
@foo=Foo.new
  end

In your view, you can then get rails to put whatever values are
currently in @foo into your fields:
  form_for :foo , :url ... do |f|
f.text_field :field1
...
  end

or:
  fields_for :foo do |f|
f.text_field :field1
...
  end

and rails will automagic in @foo.field1 as the value in that text
field because you specified ':foo'.
(Sorry, can't get my head around your models)

I was thinking that if you have an array of objects eg foo has_many
bars and you want to edit all those bars, then in the view you could
loop thru the array with an index eg:

  @foo.bars.each_with_index do |bar,idx|
fields_for bars[#{idx}] , bar do |b|
  b.text_field :field1
  ...
end
...
  end

Which, on submission, will generate
  params['bars']['0']['field1'] = some-value
  etc
Not sure if that's good but I think it works.
You could skip the whole 'with_index' thing if it's just has_one.

You'll also need to embed id value for each record into a hidden field
in your form if you're editing an existing item so that you can find
it and update it instead of creating a new object when the form is
submitted.
There are security implications here - people can post a random id
instead - so you need to think that through carefully.

[Rails] Re: Newbie needing help on Legacy DB Rails Concepts

[Daniel Bush]

I can't grasp the situation but it just seems to me that if you're
migrating old data
into a new system going forward, you should probably massage it
and get it normalized and put it into the database in one hit.
The best swiss army knives I know
of are spreadsheets (and all their functions) and databases (sql and
large data sets) for sorting this sort of stuff out.
Rails isn't necessarily the best way to do it although it might help
in some situations.

Surely table 3 and table 1 should be combined, shouldn't they?
You don't want 2 tables of agencies. You just want one and you can
tell which are registered by the fact that they do or don't have a
number against them.  Merging table 3 into 1 might be the first
thing.  If registration is more complex than that, then you may have
to set up more tables and associations to model it appropriately.

Table 2 is already linked to table 1 via legacy ID1 - assuming these
id's are ok.
So I'd get table2 into the database; pull out unique list of system
contacts and create
a separate table 'system_contacts'  (I'm assuming you've got some
other fields to put against them).  Table 2 then becomes a joining
table.  It already has the two fk's -  which you might relabel as
agency_id and system_contact_id.

Once this is done, you'll have 3 tables and 3 models and using them
would be a basic rails exercise.
I probably haven't grasped the full complexity of the relationships
here, so I'll stop there.

On Nov 13, 3:44 pm, Phil [EMAIL PROTECTED] wrote:
 Hi Daniel

 Thanks for replying so quickly. In a nutshell, yes. An Agency has many
 People. Essentially the purpose of the project is to perform an
 interim admin function to sync two systems. Hence there are two sets
 of Primary keys and two tables. The third table is the output, where
 it records the Agency business number to ensure that the Agency is
 registered. Obviously there will be multiple Agency profiles for the
 two systems with the primary keys for the agencies. Currently this is
 being done manually.

 What I want to find out now is how to generate the view to encompass
 the values from all three tables into one view, when I am using one of
 the two system generated lists as a list for users to determine if a
 client has been registered or not. E.g

 Agency ID 2 is clicked, which is linked to only one Agency Business
 Number. How do I represent the values for this Agency ID 2 from the
 other two tables? Obviously some Agency IDs will not have a
 corresponding Agency Business Number in table 3 as they have not been
 registered as yet, or in Table 2 for that matter. I am envisaging the
 use of partials.

 I worked out how to generate primary and foreign keys. Currently I
 have some code in my model that does this, but is not the best.

 Upload Model
  def self.save
     FasterCSV.foreach(D:/Rails/MySql/Migration/file.csv) do |row|
       unless Agency_ID1.exists?(row[0])
        agency = Agency.new(:OrganisationName=row[1],:TPID=row[3]) do
 |i|
           i.Agency_ID1 = (row[0])
         end
         agency.save
       end
       unless person.exists?(row[5])
       contact = person.new(:ContactFname=row[6],:ContactLname=row
 [7],:ContactPhone=row[8],
        :ContactFax=row[9],:ContactEmail=row[10]) do |si|
          i.ContactID = (row[5])
        end
        contact.save
       end
    end
 end

 It's meant to be interim code that helps me load primary key values.

 I also have a search function working with Acts_as_ferret.

 This is the model code for Agency 2 (list)

 acts_as_ferret :fields = [:OrganisationName]

 This is the controller

 class SearchesController  ApplicationController
  def index
    if params[:q]
      query = params[:q]
     [EMAIL PROTECTED] = Agency_ID2.find_with_ferret query, :page = params
 [:page], :per_page = 50
    end
    end
 end

 This is the view in views/searches

   table
     thead
       tr
         tdOrganisationName/td
         tdsmartbuy ID/td
         tdSupplier ABN/td
         tdSupplier TPID/td
       /tr
     /thead
     tbody
       % @sbtradesuppliers.each do |s| %
     tr
       td%= link_to s.OrganisationName, Agency2_path(s.id) %/td
       td%= s.Agency Business Number%/td
       td%= s.Agency ID 2%/td
     /tr
     % end %
     /tbody

 My last question is, is this restful?

 Any help would be much appreciated.

[Rails] Re: Testing modules

 I'm curious about standards on unit testing modules.

 I have a module file in my lib/ directory. Should I create a unit test

Don't know if there's a standard but I think it makes sense just to
test
it in test/unit.

 Is there any kind of naming convention used for unit test files for
 modules (some_name_test.rb or some_name_module_test.rb)?

Don't know.  If it's lib/some_name.rb then test/unit/
some_name_test.rb
seems ok with contents:
  require File.dirname(__FILE__) + '/../test_helper'
  class SomeNameTest  Test::Unit::TestCase
  ...
  end
Works for me at the moment.

I can't see the reason for using yaml like this - but I guess you have
your reasons.

Since you're set on having your controller load up a yaml file every
time it's accessed then I'd probably stick it in db/ somewhere.As
Fred says, you could put it anywhere.

You could lazy load it to save hitting the file system every time:
  class YourModel  ActiveRecord::Base
def YourModel.default_values
  @@default_values ||= YAML.load_file(RAILS_ROOT+'/db/
get_value.yml')
end

 Hi,

 -CG

I think btree is a fairly common default.  For instance it's the
default in postgres, right?
So if you just used the rails 'add_index' you'd get a btree index.
It looks like add_index doesn't pass on extra options though (there
might be some
method that does this in rails I just don't know it). So if you needed
to
specify the index method, you might have to execute the sql manually
in your migration.
  YourARClass.connection.execute('CREATE INDEX ... USING btree...')
You'll have to consult your db docs to establish its capabilities and
sql to use.

I was going to take a different tack.  Assuming this isn't a test
fixture
but just a file that is being used from somewhere to set default
values
for new objects, then you could do:

  default_values=YAML.load_file('path/to/get_value.yml')

There are probably other ways to set defaults rather than loading up a
file like this though.

You could embed them in a class method in the model and just pull them
out when you
need them.  Or maybe apply them in a callback (http://
api.rubyonrails.org/classes/ActiveRecord/Callbacks.html) like
before_create. Or use :default in your migration when defining the
table - might not be appropriate doing this with id's though.

Callback example:
class Foo  ActiveRecord::Base
  before_create :apply_defaults

  private
  def apply_defaults
self.field1='val1' if self.field1.blank?
  end
end

id_rsa is your private key and should stay on your local machine; keep

encrypt it with a passphrase.
id_rsa.pub is the public key and you can push that up to your server

ssh_options needs to know the private key so that it can authenticate

If you want to use mysql, then set up your rails project like this:

If you leave out the database option, rails will assume you want

(I think mysql used to be the default some time ago).

You can alter the database and connection settings in config/

You could access the session in the controller at the time the user
submits.
Depends on what your authentication system does.
For instance it might be session[:user].  So you have to do something
like
  user=User.find(session[:user])
or
  User.exists?(session[:user])
to verify the user id is valid.
There may be helper methods which come with whatever plugin or system
you're using
so you should check them out.

If you don't have a system, there are quite a few.
acts_as_authenticated, restful_authentication to name 2.
You'll need to install one of them and read how to use it.

  Hi.

  The problem is that Mongrel/Rails appears to hang or completely block

  ad-hoc report generation tool from within the app).

  For example, user A does a big query that takes minutes to complete.
  User B tries to do anything, but Rails seems completely dead.

  Should Rails be blocking on that query, effectively a single-user

 Yup that's the way it is. load balancing across several mongrels helps  
 a bit, but not massively because most load balancers just spread the  
 load equally - they don't prioritize mongrels that aren't processing a  
 request.
 Rails 2.2 is thread safe, but MRI's less than stellar threading means  
 that won't make a lot of difference if you are using MRI. For jruby  
 things could get very interesting.


Wow,  Looks like I'm going to have to try out jruby/rails 2.2 what

 Thanks for bringing it to my attention. Your thought process helped me
 understand better what is going on.

Take a look at a more recent post from Mark R J:
http://www.ruby-forum.com/topic/168650
He shows how you can use validates_presence_of with assocations when 
building a new object.
ie
  u.books.build(:title = 'The Comedy of Errors', :author = u)
where u is an unsaved User object (used as an author).  I can't remember 
your example exactly, but that might work for you with your current 
validations.  The way the (online) docs are worded, though, suggests 
that the AR-people intended it to be used more for foreign key fields 
than the associations based on them.
The callback before_destroy I mentioned was just a thought about how you 
might stop an olive oil source from being 'destroyed' ('delete' won't 
invoke callbacks) if it happens to be the only source for an olive oil 
object.  Anyway, you have a bunch of validations and callbacks to use to 
achieve whatever you need to do.

I can't (personally).  I would probably create an instance method in the 
model inside which I would save the model (self.save) and do other 
things like update the related model.  If you do it this way you could 
also wrap it in a transaction block to make the whole thing atomic - at 
least  you have that option anyway.

You'd pass the session value in as an argument to this method from the 
controller; your model shouldn't need to know about where the 
current_user_id came from (ie someone's http session).  This makes 
things more testable / less coupled.

That's just my thoughts.

Hashes don't guarantee any particular order.  Not sure if rails is 
sorting the hash by key as you suggest.  Maybe try array of arrays. 
Ordinarily I'd expect the order to be maintained since its an array, but 
I'm not sure:

  form.select :data , [['yes','1'],['no','0']] ,

 Hello folks,

I haven't needed to do such a thing so I'm of limited help.  I suppose 
if you're doing downloads using rails then you've probably looked at the 
streaming api:
  ActionController::Streaming
The send_data/send_file methods allow you to set the content-type and 
other headers etc etc.

So in your functional tests for your download controller, you could 
probably do something like

  def test_1a
...
get :download , params
assert_equal 'text/html',@response.headers[:type]
...

(Obviously replace 'text/html').
You can also access other headers eg content-length and the body 
(@response.body).
I don't know if it's good form to be using @response.
Integration test api is a little different so might be worth checking 
too.

cool wrote:
 I have Person model in that i have used STI like

class student person
 class parent  person

 when i am adding a student i have fields for parent also like
   i want to add a student with firstname and last name and at the same
 time i mean in the same form i wnat to add to which parent he belongs
 to in the same form i have fields like parent name, email, address

This was quite hard to read. Use full stops or bullet points or 
something.
 
 can u give idea abt this

So, you have something like
  class Person  ActiveRecord::Base ...
in app/models/person.rb
And:
  class Parent  Person ...
  class Student  Person ...
maybe in app/models/parent.rb and student.rb respectively.
And your 'people' table has a column called 'type' which is a string 
field.

In your edit form you could do something like:
 % form_for :student , :url = {:action = 'update'} do |s| %
  %= s.text_field :first_name %
  %= s.text_field :last_name %
  ... parent stuff - see below ...
  ... submit button etc ...
 % end %

Within this form you would have something like:
  %= select :selected_parent , :id ,
Parent.find(:all).collect{|p|[p.last_name,p.id]} %
which will generate a dropdown with existing parents last_names and 
their id's.

Or if you are entering parents details in alongside the student, 
something like:
  %= text_field :parent, :first_name %
  %= text_field :parent, :last_name %

Read api.rubyonrails.com and go to ActionView::Helpers::FormHelper and 
FormOptions for how to use the form fields and what they generate in 
terms of the params your controller will be receiving.

In your controller, the 'update' action would do something like:

  def update
...
@student=Student.new(params[:student])
@student.parent_id = params[:selected_parent][:id]
@student.save!

('parent_id' is a field for storing the id of the parent in your 
'people' table.)
You could save the parent using associations instead but I won't go into 
it.

If you were collecting parent details using the text fields above, you 
might have:

@parent=Parent.new(params[:parent])
@parent.save!

Hi Paulo,
I can't help directly with the output you provided but I would change 
the version of ruby for starters.  1.8.6 is the stable branch to be 
using (unless there's been some change announced with this version of 
rails).  I think 1.8.7 is more experimental and may never become the new 
1.8.6.  Also, the patch level 22 for 1.8.7 is out of date and might be a 
security issue - certainly 1.8.6 p230 which was released at the same 
time was not working well with rails even though it was meant to fix a 
security issue of the previous release.
It may be that your distro patched this version or the one prior to it 
that had the security issue, but I'd still move on if I could.

Worst case, just compile it.  It's not hard.  But you do lose the 
benefits of the distro as a result.
