 But as you can see script directory contains only one file
  rails
 

The rails command line stuff changed a lot in rails 3, to start the server you 
now do rails server, to start the console it's rails console etc.

 Here is its content:
 
 #!/usr/bin/env ruby.exe

 APP_PATH = File.expand_path('../../config/application',  __FILE__)
 require File.expand_path('../../config/boot',  __FILE__)
 require 'rails/commands'
 
 
 
 
 
 So the command
C:\Sites\helloworld\ruby script/server
 to start WebRick does not work  because  script/server file  does not
 exist.
 
 
 What do I do wrong? Please help

Re: [Rails] Rails 3 Routes

 Hi everyone,
 
 I have a nested resource that is generating the route: /events/id/
 registrations.json
 
 However, I would like to know if I can do something like this: /events/
 registrations.json
 
 With that said I have three questions:
 1) If I can do that, would the events id still be passed and give me
 access to the proper registrations related to the event?

Well the event id has to be somewhere, if not in the path then as a query param 
or in post data - you can't get rid of it completely if you need to know which 
event's registrations should be fetched

Fred
 2) How does this look in my routes file?
 3) Would there need to be a change in my controllers?
 
 You may find the code I am working with at: github.com/TheCodeBoutique/

Re: [Rails] Ajax request

 Hi
 
 I'm trying to create an Ajax request that displays a list of inventory
 items resulting from a search on a keyword.  How can I insert the list
 of inventory items using a partial or a string of html onto the page
 following the ajax request?  The following doesn't work because I
 can't use a content_tag helper method in a controller.

You can  have a view file for that action as you would for any other action

Fred
 
 I guess another question would be why doesn't the inventories div
 update and show the inventory items after the ajax request?
 
 I have this in my controller (this uses a string of html)
 
  def find_by_keyword
@inventories = Inventory.find(:all, :conditions = ['inventory_id
 LIKE ?', params[:inventory][:keyword]])
@inventories_list = @inventories.map { |inventory|
 content_tag(li, inventory['id'])}
render :inline = @inventories_list
  end
 
 And this in the view:
 
% form_remote_tag :url = { :controller =
 purchase_orders, :action = find_by_keyword }, :update=
 inventories do |f| -%
%= model_auto_completer('inventory[keyword]', '',
 'inventory[inventory_id]', '', {:method = :get})%
%= submit_tag Find! %

[Rails] help with validations

2011-05-11 Thread Quee WM

Hi,

I am trying to use the new rails 3 validations and running into some
issues.

for my password I have,

validates :password,:presence = {:on = :create},  :length = {
:minimum = 5, :maximum = 16 },  :confirmation = true

the presence and length are creating problem.

I only want to be able to check for the password at create time to
confirm if it is present.

at update time if someone enters the password it should still match the
size limit but it they do not enter the password then it should not be
looked at.

in my controller i have already added:

params[:user].delete(:password) if params[:user][:password].blank?
params[:user].delete(:password_confirmation) if
params[:user][:password].blank? and
params[:user][:password_confirmation].blank?

to take care of any issue coming from that side.

any help or suggestion will be greatly appriciated.

[Rails] Constructing an array of stuff (to send multiple apple push notifications)

2011-05-11 Thread bingo bob

I'm using this gem https://github.com/justintv/APNS to send push
notifications to an iPhone app and amazingly it works for single
notifications, such that I can do...

APNS.send_notification(Device.first.device_token,'test message')

Works great...

Now it should be a simple task (as per the docs to send multiple
notifications)

Gem says like this...

device_token = '123abc456def'
n1 = [device_token, :aps = { :alert = 'Hello...', :badge = 1, :sound
= 'default' }
n2 = [device_token, :aps = { :alert = '... iPhone!', :badge = 1,
:sound = 'default' }]
APNS.send_notifications([n1, n2])

#

for me it's slightly different, I wish to loop through each device in my
db and then send the same message to them all...it's something like this
but it's clearly not quite right... can't get the :aps = thing to work
out.

I think I need something like this on my Device model, but it's not
right - please help correct it, would greatly appreciate.



  def self.push_message_to_all(message)
devices = self.all
notifications = []
devices.each do |device|
  notifications  [device.device_token,message]
end

APNS.send_notifications(notifications)

  end

[Rails] Re: Webrick script/server file does not exist

2011-05-11 Thread garibake

Hi,

In rails 3 the file in the script folder is called 'rails' and you
need to pass in server (or s) as a parameter i.e.

ruby script\rails server

Hopefully it should now work

[Rails] Update instance variable to actual active record

2011-05-11 Thread Sebastian

I have three models as you can see below.

class Watchedfamily  ActiveRecord::Base
  has_many :watchedmembers, :dependent = :destroy
  accepts_nested_attributes_for :watchedmembers
  has_many :old_watchedmembers, :dependent = :destroy
  accepts_nested_attributes_for :old_watchedmembers
end

class OldWatchedmember  ActiveRecord::Base
  belongs_to :watchedfamily
end

class Watchedmember  ActiveRecord::Base
  belongs_to :watchedfamily
end


Now I have a method in my controller that is (for a given
watchedfamily) copying all entries of watchedmembers to
old_watchedmembers and then deleting the watchedmember entries.
Finally I am updating the watchedfamily with new watchedmembers. I
just need it for comparing old members with actual members.

Everything is working great in my database. I only have one problem in
the controller below. I need the @family.watchedmembers for a next
step, but the problem is that the @family.watchedmembers variable has
the old and the new members in its memory. The database is updated and
correct! It is only the @family.watchedmembers variable that has both
members in it.

My solution is to just call again: '@watchedfamily =
Watchedfamily.find(id)' to get the recent data from the db.

Is that the only possibily or is that bad because of additional load
on the db?


id = params[:id]
@watchedfamily = Watchedfamily.find(id)

@watchedfamily.watchedmembers.each do |member|
  params = {:watchedfamily = {:old_watchedmembers_attributes =
MyExistingMemberEntries } }
  @watchedfamily.update_attributes(params[:watchedfamily]) #copy
watchedmember to old_watchedmember
  member.destroy #destroy watchedmember
end

params = {:watchedfamily = {:watchedmembers_attributes =
MyNewMemberEntries } }
@watchedfamily.update_attributes(params[:watchedfamily]) #create
recent watchedmembers

@watchedfamily = Watchedfamily.find(id) #call the variable again from
the db to get the actual data!

@watchedfamily.watchedmembers.each do |x|
 .#some code for the next step
end

I hope someone can give me a hint!
Cheers,
Sebastian

Walter


   respond_with(@data, :include = :status)

The json result is:

last_name: Man
status_id: 1

So whats the problem? The problem is that the :include=:status seems
to not bring over the relation. In my User model I have a
belongs_to :status. How do i get this to work on a single result set?

When I do this:

   @data = User.where(id = 1)
   respond_with(@data, :include = :status)

The relation shows in the json result set fine this way. But its
within an array of objects, which i do not want.

Any ideas?

Re: [Rails] requests hanging

2011-05-11 Thread Alex Katebi

I think I have found a good solution for my background tasks.

http://kr.github.com/beanstalkd/

http://railscasts.com/episodes/243-beanstalkd-and-stalker

It's exactly what I need, and it seems to be a simple and popular solution.

 Maybe you could post your code. One thing you might want to look at is if
 you can start it using another thread --

 I avoided using Threads since I wanted my operations to be atomic.

 especially if you have something which is apparently volatile. I call
 terminal commands all the time from my code, so itself should not be a
 problem. One way to do this could be delayed_job but you can probably do it
 much more simply using a new thread. See:
 http://www.ruby-doc.org/core/classes/Thread.html


 this looks pretty good as an intro to threading, if it turns out that this
 is the correct route to go:
 http://rubylearning.com/satishtalim/ruby_threads.html

 I guess though if your process is important you will have to add some
 handling in the case of failure if it were to happen.




 How long are we allowed to delay the sending of a respond? Is there a
 better way do this in Rails way? This problem is intermittent.

 To clarify, on your server terminal window, you see no output when you
 try to access a page? And of course the page does not load, I assume. It 
 is
 probably not this if you are seeing nothing at all on the terminal, but
 sometimes if I forget to remove a debugger line and still am running the
 server in --debugger mode then of course it hangs.

 Otherwise, other obvious quations: have you restarted the server? As
 well, restarted your computer?

 Hello,

 Having trouble with generating some json. I am trying to render an

 last_name: Man

 So whats the problem? The problem is that the :include=:status seems
 to not bring over the relation. In my User model I have a

 When I do this:

 The relation shows in the json result set fine this way. But its
 within an array of objects, which i do not want.

 Any ideas?

that could be affecting the behavior of the application?

[Rails] Re: Autocomplete plugin

2011-05-11 Thread pepe

If I understand well the question the answer should be yes. If what
you mean is if it is possible to use one field on a page to find data
in more than one column in the table it should be possible the only
thing you would need is to query the table by the columns you desire
to query on.

I don't think a regex can save you here. Ask yourself a higher-level
question. Why are you gathering the address information, and why isn't
it optional? If it's to send something of value to the person you're
requesting it from by postal mail, or if you're using it to help them
find something they need nearby their home, then rest assured they
will enter it with care.

If it's anything less, you invite this sort of abuse, and you should
either just stop asking the question, or realize that a significant
percentage of entries will be undeliverable (to use the Post
Office's bloodless euphemism).

By the way, I believe the USPS has an address checker API, IIRC, I've
used it from PHP before, and there may be a Gem wrapper for it as
well. Ditto FedEx if you're using them for delivery.

When you use autocompletion, you define a field to watch, and an  
endpoint to query against. Whatever query conditions you put in the  
method that answers that endpoint will be the results that appear in  
the autocompleter's list.


So if you had generated:

new Ajax.Autocompleter('person','/people/lookup',{});

Then in Person#lookup you would be looking for

	Person.all(:conditions = ['first_name LIKE ? OR last_name  
LIKE ?'],#{params[:value]}%,#{params[:value]}%])


Crude example, but you get the idea...

I guess it might help to understand what your code is trying to do.

But if this is the code you want to execute when the server starts:

#do some magic and start the cron

You could just put that in an initializer, and it will be executed when the 
server starts.

[Rails] Help save my marriage ... correct route, so enable MVC logic v's should be regular file, trying to send it

2011-05-11 Thread Jason

Hi All,

I've been up until the small hours for the past couple of night trying
to get my Rhodes navigation working!

In essence I have the following in the root index.erb

li
a href=%= url_for :controller = :Model,
:action = :do_Action %Model/a
/li

li
a href=%= url_for :controller = :Model2,
:action = :do_Action2 %Model2/a
/li

However, Model and Model2 behave differently, thus:

Extract from rholog.txt ...


HttpServer| Decide what to do with uri /app/Model/do_Action

HttpServer| Uri /app/Model/do_Action is correct route, so enable MVC
logic

...

HttpServer| Decide what to do with uri /app/OtherModel/do_OtherAction

HttpServer| Uri /app/OtherModel/do_OtherAction should be regular file,
trying to send it

... resulting in ...

HTTP/1.1 404 Not Found

...

So my question really boils down to what does the framework use to
decide whether to treat the request as either a correct route
therefore invoking the MVC logic or as a regular file, which will
never be found as do_OtherAction doesn't exist!


Many thanks in advance,
Cheers,
Jason

[Rails] method_missing in controller

2011-05-11 Thread andreacfm

Hi,

I am using a method_missing method into a controller.
I have a route that says:

match ':controller/:action'

What surprise me is that if a view that match the action name exists
method_missing is not invoked but rails happily render the view.
I was expecting that method_missing was going to be invoked if
declarated.

Is that a normal behaviour?

Thanks

[Rails] ROR 3 model associations

2011-05-11 Thread ggroupnick

Hi all,

I am new to ROR3 and would really appreciate some advice on how to
define the following model association:

Game model - has host_userid and visitor_userid as fields to define
the two players engaged in the game. this two
  fields are of type User and need to be mapped
via foreign key relationship.

User model -   a user object can belong to one or more games (as I
imagine .. I would fetch that by querying the
 Games table where the host_userid or
visitor_userid equal to the userid in question)


if anyone could post a code snippet to define such associations Id be
really grateful :)

I repeat my earlier point. If it's not valuable enough to the user,
they will spam you like this. If your geocoder reports an error, then
raise it to the user, tell him or her sorry, having trouble with that
location, could you check the address again?

You may be able to find a gem that wraps the USPS database, or FedEx's
(with an API key from FedEx, and weeks of back-and-forth with their
approval team). But it still gets back to the original value to the
user question. What exactly do you give them in return for their
successful entry of a real address? Do *they* think it's valuable?

First look in development.log to see if it is being passed with the
request ok.  Then use ruby-debug to break into your code in the
controller action (create or update presumably) and you can inspect
the data to work out where it is getting lost.  See the Rails Guide on
debugging to find how to do that.

Re: [Rails] Re: Regex Validation

2011-05-11 Thread Philip Hallstrom

 Walter
 Im using address to geocoding. Do you know if exists an address check
 plugin or gem to do this work?
 
 Thanks
 
 Pedro
 
 
 I repeat my earlier point. If it's not valuable enough to the user, they will 
 spam you like this. If your geocoder reports an error, then raise it to the 
 user, tell him or her sorry, having trouble with that location, could you 
 check the address again?
 
 You may be able to find a gem that wraps the USPS database, or FedEx's (with 
 an API key from FedEx, and weeks of back-and-forth with their approval team). 
 But it still gets back to the original value to the user question. What 
 exactly do you give them in return for their successful entry of a real 
 address? Do *they* think it's valuable?

+1 for everything Walter has said about requiring it...

Also... my memory is that yes the USPS has this ability, but it's not free (and 
quite expensive).  Google can do it as well.  Look into the geokit-rails stuff. 
 It won't help with sanitizing the input, but it will turn it into a lat/long 
pair if it can.

If location isn't super super important, just ask for their zip code.  That's 
certainly granular enough to do nearby type functionality.

Good luck!

 I don't think a regex can save you here. Ask yourself a higher-level
 question. Why are you gathering the address information, and why isn't
 it optional? If it's to send something of value to the person you're
 requesting it from by postal mail, or if you're using it to help them
 find something they need nearby their home, then rest assured they
 will enter it with care.
 
 If it's anything less, you invite this sort of abuse, and you should
 either just stop asking the question, or realize that a significant
 percentage of entries will be undeliverable (to use the Post
 Office's bloodless euphemism).
 
 By the way, I believe the USPS has an address checker API, IIRC, I've
 used it from PHP before, and there may be a Gem wrapper for it as
 well. Ditto FedEx if you're using them for delivery.

Re: [Rails] Rails 3 Routes

2011-05-11 Thread Chad Eubanks (gMail)

Fred,

I understand I can not get rid of it completely.  The reason I am asking this 
is this:  I have a client side app that sets a proxy to the URL path with an 
extension .json.  

The events id is not a constant integer and therefore I can not set the proxy 
URL to an explicit events id.  

I need to have a constant URL path of events/registrations.json.  From what you 
are saying.  It sounds like it can be done but can you elaborate for me please. 

 This might be a better example: users/id/posts.json.  When user one logs 
in the related posts are shown.  When user two logs in the related posts are 
shown.  However, the id can not be shown in the url.

Kind Regards,
Chad Eubanks

 Hi everyone,
 
 I have a nested resource that is generating the route: /events/id/

 However, I would like to know if I can do something like this: /events/
 registrations.json
 
 With that said I have three questions:
 1) If I can do that, would the events id still be passed and give me
 access to the proper registrations related to the event?
 
 Well the event id has to be somewhere, if not in the path then as a query 
 param or in post data - you can't get rid of it completely if you need to 
 know which event's registrations should be fetched
 
 Fred
 2) How does this look in my routes file?
 3) Would there need to be a change in my controllers?
 
 You may find the code I am working with at: github.com/TheCodeBoutique/

 I guess it might help to understand what your code is trying to do.

 But if this is the code you want to execute when the server starts:


 #do some magic and start the cron

 You could just put that in an initializer, and it will be executed when the

[Rails] Re: ROR 3 model associations

If you phrase it slightly differently, the code for associations almost 
writes itself:

Game has one host to class User
Game has one visitor to class User

User has many hosting games to class Game
User has many visiting games to class Game

By default when you create an association, rails will use the model name 
plus _id to determine the foreign key. This isn't what you want, since 
game has 2 foreign keys to user. Adding the class_name option makes it use 
the name of the association and the class name plus _id. In this case, 
host_user_id and visitor_user_id.

So you can define it like this:

class Game
  has_one :host, :class_name = User, :inverse_of = :hosting_games
  has_one :visitor, :class_name = User, :inverse_of = :visiting_games
end

class User
  has_many :hosting_games, :class_name = Game, :inverse_of = :host
  has_many :visiting_games, :class_name = Game, :inverse_of = :visitor
end

 Works great...

 Now it should be a simple task (as per the docs to send multiple

 n2 = [device_token, :aps = { :alert = '... iPhone!', :badge = 1,

Have you tried that?  It doesn't look like valid ruby to me (even with

 for me it's slightly different, I wish to loop through each device in my

 but it's clearly not quite right... can't get the :aps = thing to work
 out.

 I think I need something like this on my Device model, but it's not

  def self.push_message_to_all(message)
    devices = self.all
    notifications = []
    devices.each do |device|
      notifications  [device.device_token,message]

Once you have got the manual example above working the use ruby-debug
to break in here and have a look at notifications and see if it is of
the same form as if you break into the manual test and look at it
there.

+1 to everything Walter has said, as well.

I haven't thought about this a lot, but doesn't this apply to everything in
terms of user input? Doesn't this really enter the realm of a basic
guideline, principle, or law for UI? (I remember something like this being
applied to database design.)

 Don't make people enter data that they don't care about.

 Don't make people enter data that doesn't affect anything.

 Carefully evaluate whether people really need to enter data.

 If people feel free to enter garbage in a field, should that data
really be asked for?

Aren't there, potentially, corollaries to this? For instance, Always allow
the people entering data to easily correct or remove their data.

  plugin or gem to do this work?
 
  Thanks
 
  Pedro
 
 
  I repeat my earlier point. If it's not valuable enough to the user, they
 will spam you like this. If your geocoder reports an error, then raise it to
 the user, tell him or her sorry, having trouble with that location, could
 you check the address again?
 
  You may be able to find a gem that wraps the USPS database, or FedEx's
 (with an API key from FedEx, and weeks of back-and-forth with their approval
 team). But it still gets back to the original value to the user question.
 What exactly do you give them in return for their successful entry of a real
 address? Do *they* think it's valuable?

 +1 for everything Walter has said about requiring it...

 Also... my memory is that yes the USPS has this ability, but it's not free
 (and quite expensive).  Google can do it as well.  Look into the
 geokit-rails stuff.  It won't help with sanitizing the input, but it will
 turn it into a lat/long pair if it can.

 If location isn't super super important, just ask for their zip code.
  That's certainly granular enough to do nearby type functionality.

 Good luck!

[Rails] Re: Autocomplete plugin

2011-05-11 Thread Mlle

Thanks for your comments.  I understand what you're saying but I guess
my question had more to do with the population of the actual list, not
the database query.  If you use the autocomplete plugin, the list that
populates under the input box has to be a certain field of a certain
model.  For example, when you call this helper:

model_auto_completer_result(@inventories, :inventory_id )

the inventory_id is displayed for each inventory item matching the
query.  I'd like to search on two fields in the inventories table and
display whichever field matched in the autocomplete list.

 When you use autocompletion, you define a field to watch, and an  
 endpoint to query against. Whatever query conditions you put in the  
 method that answers that endpoint will be the results that appear in  
 the autocompleter's list.

 So if you had generated:

 new Ajax.Autocompleter('person','/people/lookup',{});

 Then in Person#lookup you would be looking for

         Person.all(:conditions = ['first_name LIKE ? OR last_name

 Crude example, but you get the idea...

Re: [Rails] Help save my marriage ... correct route, so enable MVC logic v's should be regular file, trying to send it

which tool you are using to develop Rhodes applications?

On Wed, May 11, 2011 at 6:53 PM, Jason jason.mcneil@googlemail.comwrote:

 Hi All,

 I've been up until the small hours for the past couple of night trying
 to get my Rhodes navigation working!

 In essence I have the following in the root index.erb

li
a href=%= url_for :controller = :Model,
:action = :do_Action %Model/a
/li

li
a href=%= url_for :controller = :Model2,
:action = :do_Action2 %Model2/a
/li

 However, Model and Model2 behave differently, thus:

 Extract from rholog.txt ...


 HttpServer| Decide what to do with uri /app/Model/do_Action

 HttpServer| Uri /app/Model/do_Action is correct route, so enable MVC
 logic

 ...

 HttpServer| Decide what to do with uri /app/OtherModel/do_OtherAction

 HttpServer| Uri /app/OtherModel/do_OtherAction should be regular file,
 trying to send it

 ... resulting in ...

 HTTP/1.1 404 Not Found

 ...

 So my question really boils down to what does the framework use to
 decide whether to treat the request as either a correct route
 therefore invoking the MVC logic or as a regular file, which will
 never be found as do_OtherAction doesn't exist!


 Many thanks in advance,
 Cheers,
 Jason

Re: [Rails] Re: Call a task when server starts

That actually makes sense. Rails waits for the initializer to finish running 
before running the rest of your application. So if you have an infinite loop 
in there, it'll never finish running.

Might be best to spawn another process using Thread or just run that code as 
part of a cron job or other manual process.

Would help to understand what your code is trying to do.

Back up to the line where you define @inventories. That's where you

Re: [Rails] unobtrusive javascript - attaching a .js.erb page

2011-05-11 Thread Chris Mear

On 9 May 2011 14:30, Sergio Ruiz li...@ruby-forum.com wrote:
 i saw on one of the railscasts that using unobtrusive javascript, you
 attach your javascript to your page like so:

 if your view is:

 index.html.erb

 you could add a page named:

 index.js.erb

 and that javascript would be included on the load for that page.

 for some reason, it is not working for me..

 is there something i need to do to trigger this behavior?

There is no such behaviour in Rails; I think you might have
misunderstood the screencast.

Assuming you are talking about this:

http://asciicasts.com/episodes/205-unobtrusive-javascript

then the 'index.js.erb' is rendered when your browser makes an AJAX
request to the 'index' action (in the same way that 'index.html.erb'
is rendered when your browser makes an ordinary request to the index
action).

These are two completely separate requests. index.js.erb is *not*
being inserted into a script tag in index.html.erb.

If you want that kind of thing to happen, you'll need to write a
custom view helper (and probably choose a more appropriate path for
your automatically-included JavaScript files, so that they don't
conflict with the standard behaviour described above).

[Rails] Extending/reopeining class and use of super

A question on a couple things relating to extending a class and the use of
super.

In my main application I have the following class which extends an engine
class:

class User  ActiveRecord::Base
  def self.find_for_database_authentication(login_value,
omniauth_provider=nil, omniauth_uid=nil)
super if login_value
where('omniauth_provider=? AND omniauth_uid=?', omniauth_provider,
omniauth_uid)
  end
end

And the engine has this class:

class User  ActiveRecord::Base
  def self.find_for_database_authentication(login_value)
where([username = :value OR email = :value, { :value = login_value
}]).first
  end
end

When I run a spec to try out the method, I get this error:
Failure/Error:
User.find_for_database_authentication(@user.username).class == User
 NoMethodError:
   super: no superclass method `find_for_database_authentication' for
#Class:0x1057bbfa0

I do understand why -- my application class is not a subclass of the engine
class, I am just extending the class. This leaves me with the question if
there is a way to have access to the original method (like using super in a
subclass situation) so I would not have to duplicate that code (I would have
subclassed my class to the engine class but is a bit nasty as they share the
same name, and that is structurally how the app is loaded)?

Also, I am confused also as to why I see in places that to extend a class
they use MyClass.class_eval do . whereas it seems that if I just do
what I have above, I get the same ability. Am I missing something?

Anyhow, any comments appreciated!

Re: [Rails] Rails 3 Routes

Not if you're grabbing it from somewhere. The ID MUST be somewhere, or
the find will fail.

@user = current_user

if you're using any sort of common authentication framework. From
there, @user.posts is a drop-kick away.

 Hi,

 I am trying to use the new rails 3 validations and running into some

 the presence and length are creating problem.

 I only want to be able to check for the password at create time to

 at update time if someone enters the password it should still match the
 size limit but it they do not enter the password then it should not be
 looked at.


My sense is that what is tripping things up is that on update and nil
password, it is not checking precence but is still checking length and
confirmation. It may not be the best way but I tend to use an :if =
:method_name, and then in that method check for new_record, etc.



 in my controller i have already added:

 params[:user].delete(:password) if params[:user][:password].blank?
 params[:user].delete(:password_confirmation) if
 params[:user][:password].blank? and
 params[:user][:password_confirmation].blank?

 to take care of any issue coming from that side.

 any help or suggestion will be greatly appriciated.

I tried but the thing is that the way the engine loads, the engine class and
my class have the same name and reside in the local app. I guess I could
give my class a different name to subclass it if I dont want to dup the

 +1 to everything Walter has said, as well.

 I haven't thought about this a lot, but doesn't this apply to everything in
 terms of user input? Doesn't this really enter the realm of a basic
 guideline, principle, or law for UI? (I remember something like this being
 applied to database design.)

  Don't make people enter data that they don't care about.

  Don't make people enter data that doesn't affect anything.

  Carefully evaluate whether people really need to enter data.

  If people feel free to enter garbage in a field, should that data
 really be asked for?

 Aren't there, potentially, corollaries to this? For instance, Always allow
 the people entering data to easily correct or remove their data.


Also, coming from one who has written address validation for credit
reporting, you would not believe the complexity --- think of po boxes,
boxes, railroad stops, prefixes/suffixes (w,nw,s,...), apartments, suites,
rooms I dont remember exactly why I had to do it but it was one of those
things I thanked god that I was using tdd :)

  I repeat my earlier point. If it's not valuable enough to the user, they
 will spam you like this. If your geocoder reports an error, then raise it to
 the user, tell him or her sorry, having trouble with that location, could
 you check the address again?
 
  You may be able to find a gem that wraps the USPS database, or FedEx's
 (with an API key from FedEx, and weeks of back-and-forth with their approval
 team). But it still gets back to the original value to the user question.
 What exactly do you give them in return for their successful entry of a real
 address? Do *they* think it's valuable?

 +1 for everything Walter has said about requiring it...

 Also... my memory is that yes the USPS has this ability, but it's not free
 (and quite expensive).  Google can do it as well.  Look into the
 geokit-rails stuff.  It won't help with sanitizing the input, but it will
 turn it into a lat/long pair if it can.

 If location isn't super super important, just ask for their zip code.
  That's certainly granular enough to do nearby type functionality.

 Good luck!

[Rails] Duplicate method in application_controller and application_helper

2011-05-11 Thread Walter Lee Davis


I have a method:

  def current_practice
if session[:impersonating]
  Practice.find session[:impersonating]
else
  current_user.practice
end
  end

It is identical in both controller and helper. How could I DRY this up  
so I only need maintain it in one place?


I already have the line

helper:all

at the top of my ApplicationController, but when I commented out the  
current_practice in the controller, the one from the helper didn't  
step in. Maybe I'm misunderstanding what that line is meant to do.

[Rails] Running Ruby/Rails Specs with database inserts from non-default spec sub-directory

2011-05-11 Thread egervari

Hi everyone!

I have a question on how to setup my tests a bit differently than the
defaults.

By default, Rails with RSpec installed provides you with directories
such as spec/models, spec/controllers, etc.

When i use before(:each), I notice that Rails properly cleans out the
database in these specs automatically.

However, I created a new sub-directory called spec/queries. My
intention was to put all of my query-related tests here so that the
database setup code didn't run with the model validation and business
logic tests (for speed and organization reasons). I will have a lot of
complex queries that will need to be tested against a mini-database...
so this seems like the right thing to do (or is there a better
solution?)

When I put these tests in spec/queries folder and run the tests
multiple times, Rails complains that data is not unique and so on...
so I am guessing that the data is not getting cleaned out now? Yes, I
am using factory girl with sequences, so this is probably a database
cleaning problem. I didn't have it before when these same tests were
in 'specs/models'.

1. Do I need to manually clean out the data since I moved the specs
into it's own spec/squeries subdirectory?

2. Is there any way to include spec/queries to the list of directories
that get auto-cleaned, much like spec/models does?

Thanks

There is a gem called database_cleaner which might help in your case to run
before your test/suite.

 There is a gem called database_cleaner which might help in your case to run
 before your test/suite.

Well, I'm looking into that now... and it mostly works (But not
quite... it seems like there are some records hanging around still).

Why do I not need the database cleaner for the model tests... but I do
for this new spec/queries directory? Can I simply tell rails to treat
this directory the same as it treats spec/models? The tests work in
that folder.

[Rails] [Model Scopes] How to count a nested

2011-05-11 Thread danimashu

Hello, I have a Post that has_many Comments. I have the next scopes:

scope :valid, where('created_at = ?', 2.months.ago)
scope :expired, where('created_at  ?', 2.months.ago)

Now, I would have a scope named :commented that return all the Post
that have more than 0 Comments but I don't know how do it clearly. A
solution is have a counter num_comments column in Post, but I don't
know if that is the best practice.

Thanks for your advices. Bye.

[Rails] Recurring Billing API Integration w/ SAAS provide, i.e. Cheddargetter

spreedly, recurly or braintree, can you kindly outline tips about what
to do in MVC or your sample code?  Your help is greatly appreciated.

user$ echo '[[ -s $HOME/.rvm/scripts/rvm ]]  .
$HOME/.rvm/scripts/rvm # Load RVM function'  ~/.bash_profile


Now you are suppose to run it from a shell. The old way was:

[[ -s $HOME/.rvm/scripts/rvm ]]  . $HOME/.rvm/scripts/rvm

which you add it to your .bashrc file.

I had the same stupid problem.

 Hello, after upgrading to ubuntu 11.04 im having this problem with

 Git is installed OK, when I follow the instructions on RVM website
 aparently its OK too, but when I close my terminal and open a new one
 and tipe ruby -v ou rvm -v for example I got a messenge rvm is not

[Rails] polymorphic and sti problems.

2011-05-11 Thread Perry Smith

I'm way back at Rails 2.3.5.  I can move up to 2.3.11 if anyone thinks
that will help.  My problem is this:

class Entity  ActiveRecord::Base
  belongs_to :item, :polymorphic = true
end

class Name  ActiveRecord::Base
  has_one :entity, :class_name = Entity, :as = :item
end

class Team  Name
end

The has_one does not work.  It searches for the base_class of item
Name instead of the class Team.  I see where these is a trick
where you can change item_type= in the documentation but that causes me
other problems.

I tried moving the has_one to Team but that didn't change anything.

Any suggestions?

 The rails command line stuff changed a lot in rails 3, to start the server
 you now do rails server, to start the console it's rails console etc.

[Rails] TypeError: can't convert nil into Integer

2011-05-11 Thread Tim Uckun

I am getting this error with a very simple model and schema. The
record saves even though an error has been generated. I have tried
this with both postgres and mysql.

Here is the model.

class Person  ActiveRecord::Base
end

Here is a transcript..

 p = Person.new

Here is the migration

 create_table :people do |t|

  t.date   :date_of_birth

  t.integer :age
  t.string :gender
  t.string :email
  t.integer :state , :default = 0
  t.integer :status , :default = 0
  t.timestamps
end

add_index :people, :email
add_index :people, :hash
add_index :people, :state

So there is nothing weird at all.

Very strange
