[Rails] rspec test cannot be passed when render partial in layout
I have a problem stuck me couples of days, could anyone help me? Thanks very much. The problem is that rspec test cannot be passed when the layout contains :partial, once i removed the :partial, the rspec test passed successfully. I could not find out the reason. Below is my code: application.html.erb <%= render :partial => 'shared/header' %> <%= yield %> <%= render :partial => 'shared/footer' %> users_controller_spec.rb describe UsersController do describe "Requesting /forgot_password using GET" do it "should be successful" do get :forgot_password end end end --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: Opening file content into a textarea
in ruby there is the class File: http://www.ruby-doc.org/core/classes/File.html to get the contents of your file try something like: my_file = File.new(path_to_file, 'r') @my_file_content = my_file.read my_file.close now you can show your content inside the text area (you should know how to build a simple form for it). after editing it, back in your controller write the updated contents to the file: updated_content = params[:whatever] my_file = File.new(path_to_file, 'w') my_file.write(updated_content) my_file.close --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

try a current_user.reload or current_user.pending_friends_by_me.reload in your controller after the save. maybe this helps. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: Download Movie through link
if i understand correctly you can click that link, choose the option 'save as', download it to you hd and watch it. but you if you click the link and choose 'open', your video player opens but doesn't show any content. correct? if so i don't think it's a problem with your rails app, but with your operating system. because as i understand it, the file gets send correctly. maybe try another video-player. are you able to open other videos on the net (maybe upload one to a ftp and open it with your browser)? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] form_remote_tag comes back before saving really done?
Hi,
I am having troubles with a form_remote_tag.
I have this form:
<% form_remote_tag :url => { :action => 'create', :controller =>
'invitations' } do %>
<%= hidden_field_tag 'invite', user.id %>
<%= hidden_field_tag 'command', 'invite_user' %>
<%= submit_tag('Invite') %>
<% end %>
That ends up if the a controllers function (after entering from
create...):
def invite_user(friend_to_invite)
invited_user = User.find(friend_to_invite)
current_user.request_friendship_with(invited_user)
invitation = Invitation.new
invitation.user_id = current_user.id
invitation.status = 0
if invitation.save
@pending_friends_by_me = current_user.pending_friends_by_me
puts "@pending_friends_by_me"
puts @pending_friends_by_me
puts "/@pending_friends_by_me"
render :update do |page|
page[:sent_invitations].replace_html :partial =>
"sent_invitations"
end
return
end
end
_sent_invitations is the partial that shows the contents of
@pending_friends_by_me. So you press the button on the form and this
partial is updated with the current invitations sent.
THE PROBLEM
Whe the partial is updated from the function above it still doesn't
contain the updated @pending_friends_by_me, the last invitation is not
visible. It returns to the view but the contents are still the same. If
I just refresh the page then the partial gets all the invitations.
How to solve this?
-
I went to the model and used the after_save callback, when that is
called inspecting the invitations then all of them are already present.
But didn't have access to render functions there, and I don't think I
should actually call it from ther anyway.
Any hints?
Thanks.

You can do this by generating a temporary token (random value) that you include in a url you mail to the user and set it to expire within a few minutes of being generated.

Hi Fred, thanks so much for your response, that is exactly what I was
looking for. What do you mean by rjs can be a bit of a crutch? What
do you mean by rewriting the whole thing as a js function. You mean
just something like resetVisibility() and then just reset both the
end_drop and start_drop elements within the resetVisibility function?

[Rails] Transaction block still sets id on model/new_record to false on rollback
I'm on Rails 2.2.2 on MySQL with InnoDB table types. I'm running into
a wierd bug where if I have two models in a transaction and the second
model raises an exception, the first model still has it's ID set and
it's new_record status set to false despite the row the ID is set to
never existing.
The following is a console session showing this:
>> client_user = new_client_user( :first_name => nil ) # Will cause validation
>> to fail
=> #
>> establishment = new_establishment( :brand => brand )
=> #
>> Establishment.transaction{ establishment.save!; client_user.save! } rescue
>> false
=> false
>> establishment.id
=> 10
>> establishment.new_record?
=> false
>> client_user.id
=> nil
>> establishment.reload
ActiveRecord::RecordNotFound: Couldn't find Establishment with ID=10
>> Establishment.count
=> 4
Here's an explanation of the session:
1) I initialise a new client user, with first_name set to nil so it
will fail a validation
2) I then initialise a new establishment model
3) I try and save both in a transaction block. The client_user.save!
call raises an exception causing the block to roll back.
4) Yet establishment has an ID set to 10 and is marked as not being a
new record.
5) As expected client_user has no ID
6) Calling reload on establishment throws an error because the row
does not exist
7) Counting up the actual rows we see it is below the ID assigned to
establishment (I did this a few times, the first time the assigned ID
was 5, then 6, then 7 etc)
Am I missing something or is this expected behaviour?

[Rails] Column not in table (legacy database)
I have been pushing my way through the issues regarding using legacy
database tables and I am making some progress but have run into a
couple of challenges.
The test application I am working with has an employee master file
that has a primary key called "emssan". I have an employee job record
that has a primary key of "shssn". There is one, and only one, job
record for each employee record. I needed to join to the employee
master file to get the name to display on the job record so I built
this relationship:
class Job < ActiveRecord::Base
set_primary_key "shssn"
def self.table_name() "psts301" end
belongs_to :employee, :foreign_key => "shssn"
end
class Employee < ActiveRecord::Base
has_one :job
set_primary_key "emssan"
def self.table_name() "peis301" end
def name
"#{emfnam} #{emlnam}"
end
end
When I display the index, I get a list of employees with names.
Great. When I take the option to show the record, I get a record
returned to view. However, if I take the option to create or edit, I
get an error
Request Failed (code 500, Internal Error)
The log shows the following:
Column EMPLOYEE_ID not in table PSTS301
The question is: Why is Rails looking for a key called EMPLOYEE_ID
when I set the primary key value to "emssan"? How do I fix this?
Thanks

[Rails] Trying to make this application RESTy
Ok, here's the basic workflow: 1) A user inputs an order for a customer. This consists of several line items of equipment rental. (So, for example, 3 trucks at 7 am, 7:30, and 8am for June 23). (Ok, this part is easy... a standard Order resource with the usual CRUD actions) 2) A user (may be the same as #1, or may not) must fulfill the order, so he must be able to pull up a list of unassigned work (for a particular day, for example), see this work is still unassigned and assign 3 trucks to this job. (This is where things get fuzzy. Is this specialized index action on Order? I don't think so because we're editing the orders, not just listing them. Is this a separate resource?) 3) A user (may be the same, may not) must later go back and fill out the hours the trucks actually worked, so they must first be able to pull up a list of all work which has been completed to date and see this work has been assigned but not yet recorded. (Same problem... is this another resource, or another view on the resource in number 2?) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Rails 2.2, abstract_class, and associations
In my project, I've created an abstract model that my real models inherit from. In my abstract model, I've overridden method_missing so that I can use attribute names without the field type prefix from the legacy database, without having to set up alias_attribute for every attribute in every table. class LegacyModel < ActiveRecord::Base self.abstract_class = true def method_missing(symbol, *args) ...do some stuff... end end This all worked fine in Rails 2.0.2. It still works in Rails 2.2.2, but now not across a belongs_to association. It does work across a has_many association. NoMethodError: NoMethodError from /Library/Ruby/Gems/1.8/gems/activerecord-2.2.2/lib/active_record/ associations/association_proxy.rb:209:in `method_missing' Anyone have any ideas on either a better way to handle the attribute names, or where to start looking to figure out how to make this work?

I've got a remote machine on my network which has Ubuntu as the OS. I run my testserver on it with all my current PHP sites. All I have to type on my main Vista Machine as the URL is "http://testserver"; and it takes me to the index page i've created with links to all my sites on that remote Ubuntu machine.

My second Question is, Where are the config files to tell RoR to use the MySQL database I currently have setup on the testserver that phpmyadmin is also using?

You would actually be "sending" the data to the server, which would then save the data from the server-side. But, it would give you access to data stored in JavaScript variables allowing you to send it to the server for processing via XMLHTTPRequest (XHR). Also note that you don't actually have to use a JavaScript framework to use XMLHTTPRequest, but the frameworks sure make things much easier, and browser independent. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: ThroughAssociations
It is hard explain without example.
I need Full-Text Search
SELECT * FROM products WHERE MATCH(name) AGAINST('lamp') ORDER BY name
Returns:
"alarm lamp"
"lamp"
"trouble lamp"
"wall lamp"
But: SELECT * FROM products WHERE MATCH(name) AGAINST('lamp') ORDER BY
name!='lamp', name
Returns:
"lamp"
"alarm lamp"
"trouble lamp"
"wall lamp"
Note difference, first result is "lamp" exactly same as search word was,
and after that comes "alarm lamp" and so on..
So now we only add: catalogues.name, catalogue_items.position,
products.name, products.price to results...

[Rails] Legacy Schemas dynamic find
Hello, I'm trying to put a rails face on a legacy database. It is an old Sybase 11 database installation. I've gotten an ODBC connection working that uses unixODBC and FreeTDS to work. I'm also using the activerecord-odbc-adapter gem. I've had to use set_table_name and set_primary_key to make it work so far. However, none of the dynamic find_by methods work. I always get a method missing error. Also, find through association doesn't work as well with the same error. Normal finds on the models work, but I was hoping I can shorthand some of this. Am I SOL on this because it's a legacy DB or is there something I can do or check to make that work? If I can, that would save me some work writing find_by_sql calls.

It actually > refer to the class name or table name? ** really confuse >_<. Can > someone explain it? Is it a convention of rail? Thank you. My guess is that English is not your native language. This might be why you are confused by the Rails conventions, which follows English singular/plural conventions. Here's the scoop. I hope you can follow along: First let's look at a Rails model object. The model class is like a prototype (or template) representing a single row in a database table. This is why the model class name is singular. Example: class Physician < ActiveRecord::Base ... end The database table that stores each physician contains a collection of physicians, which is why the table name is plural. Rails associations can represent either one or many model objects. Associations described as either has_one or belongs_to represent one object and therefore use the singular form: Examples: class Appointment < ActiveRecord::Base has_one :physician # This is one Physician object (singular) end class Appointment < ActiveRecord::Base belongs_to :physician # This is one Physician object (singular) end Note: Notice that has_one is used for one side of a one-to-one association. There other side would use belongs_to. Example: class Unicycle << ActiveRecord::Base has_one :wheel end class Wheel << ActiveRecord::Base belongs_to :unicycle end Associations described as has_many refer to a collection (array) of objects and therefore use the plural form: Examples: class Physician < ActiveRecord::Base has_many :appointments # This is an array of Appointment objects (plural) end I hope this makes things a little more clear to you. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

First of all, amend your association in Catalogue as follows - this will
mean that the catalogue's items (and therefore products) will
automatically be ordered by position.
Catalogue
has_many :catalogue_items, :order => "position"
Then, in the controller:
#do an include to eager load the relevant associations.
@catalogues = Catalogue.find(:all, :conditions => ["name like ?",
"#{a_variable}%"], :include => {:catalogue_items => :products})
And then, for example, in the view:
<% @catalogues.each do |catalogue| %>
Catalogue:<%= catalogue.name %>
<% catalogue.catalogue_items.each do |item| %>
<%= item.position %>: <%= item.product.name
%>: <%= item.product.price %>
<% end %>
<% end %>
Obviously you can put your own html around this, this is just a simple
example.

[Rails] Can replace_html change the value of an input text?

I'm updating one area with one partial, using a page of .js.rjs,
and the code:
page.replace_html("div_list", :partial => "list", :object =>
@expedients)
Also, I would like to empty the field value that I use to send the Ajax
request, but I can't make it to work, maybe it's not possible with
page.replace ...
seudo code:
page.replace_html("expedient_reference", :partial => "blank",)
Basically I want to change the value of the id expedient_reference:
Referencia
is this possible ?

Yummy :-). if you're using prototype you can replace
$('end_drop_foo').style.display = 'block';
$('end_drop_foo').style.visibility = 'hidden';
with
$('end_drop_foo').setStyle({display: 'block', visibility: 'hidden'})
If i were you I'd have in my application.js a function like
function resetVisibility(element){
element.setStyle({display: 'block', visibility: 'hidden'})
}
then then your rjs stuff looks like
resetVisibility('end_drop_#{params[:day]}_#{params[:appt_counter]}')
resetVisibility('start_drop_#{params[:day]}_#{params[:appt_counter]}')
or even right the whole thing as a js function (RJS can be a bit of a
crutch)

Rails provides an implementation which is just a plain old model class but you can replace that with one that just issues raw sql statements (mostly in the interest of speed). An example one is included with rails. Obviously if you didn't know any of that you probably haven;'t done that :-) In the absence of all that created_at and updated_at should update automatically as it is just a regular ActiveRecord class. Dumb question: did you restart your mongrel or whatever is handling your requests after you added that column ?

[Rails] remote_form_for file_field strangeness
Does anyone see any problem with this form?
- form_remote_for(Photo.new, :html => {:multipart => true, :target
=> :uploader}) do |f|
.form_element
= f.label :photo
= f.file_field :collateral
= hidden_field_tag :container_id, @shoot.id
= hidden_field_tag :container_type, @shoot.class.name
.form_element
= f.submit 'Add Photos'
The photo has a paperclip attachment called collateral, and a double
polymorphic relation with container (which can be a shoot, model or
photographer). At the bottom of the page is an iframe with the id and
name 'uploader'. However, when submitted via AJAX, it never
serializes the file_field: both the development log and firebug both
only show the hidden params being passed. It works fine as a
form_for, however.
I'm using 2.2.2 on OSX 10.5.6 and the responds_to_parent plugin to,
well, respond.
Thanks,
Todd

[Rails] Sending explicit js to browser from RJS
I am using jQuery with the rails defaults in my app and would like to
call jQuery commands from my RJS templates or from respond_to blocks.
I've seen this used in a railscast:
page << "jQuery('some_id').css('color','red');"
but I'd like it to execute with the others, namely:
page.visual_effect :highlight, 'some_id'
page << "jQuery('some_id').css('color','red');"
Am I going about this the wrong way, or should this be working?

[Rails] Expiring cache from a rake task
Hello,
I have a question on cache expiration only working from the web, and not
from the console or from a rake task.
I have 2 models, Post e Comments.
I have this page /archives where I list all old posts.
I created a controller 'archives', where I have a page cache (caches_page
:index).
I need to expire this page cache, every time a Post or Comment is
created/updated/destroyed.
Using sweepers, this works 100%. (
http://www.railsenvy.com/2007/2/28/rails-caching-tutorial#sweepers)
The problem is that, now, I implemented spam moderation by Akismet.
So when a new comment is created in the database, it gets a 'pending'
status. And there's a rake task that runs every x minutes, in order to check
all 'pending' comments against the Akismet database, and only then comments
earn an 'approved' or 'spam' status. And it's only then that I should expire
the /archives page.
So I need to expire a cached page, from something that happens outsite a
controller. And it seems the only situation a sweeper works is when the
event is triggered by the web.
If I open the console, add a new comment to a post, nothing happens (ok!).
And now I run the Akismet check, and assuming it gives the comment an
'approved' status, the cache is not expired, when it should be.
I tried to use Observers, from the Rails docs (
http://www.railsbrain.com/api/rails-2.2.2/doc/index.html?a=M001871&name=observe
).
In environment.rb I added the line: config.active_record.observers =
:archives_observer
I created the file app/models/archives_observer.rb with:
class ArchivesObserver < ActiveRecord::Observer
observe :post, :comment
def after_save(record)
expire_page(:controller => 'archives', :action => 'index')
end
end
But I get an error: NoMethodError: undefined method `expire_page' for
#
I tried this also:
class ArchivesObserver < ActionController::Caching::Sweeper
(...)
In this case, there's no error, and it does nothing at all. The
public/archives.html just stays there.
I'm trying my best to avoid hacking it, using a simple File.delete :)
Like the code below:
# File rails/actionpack/lib/action_controller/caching/pages.rb, line 65
65: def expire_page(path)
66: return unless perform_caching
67:
68: benchmark "Expired page: #{page_cache_file(path)}" do
69: File.delete(page_cache_path(path)) if
File.exist?(page_cache_path(path))
70: end
71: end
Is there a way to expire pages without having to hack it?
Thanks a lot,

[Rails] Re: Sessions do not update created_at column?
Created_at is supposed to be filled only at creation time, right? Shouldn't you use updated_at instead?

[Rails] Re: Initialize database connection when my rails project start
hi Fred, Thank you for your reply. I just load the script in config/initializers and make the conn_pool to @conn_pool. It work fine. But I want to learn more. Could you further elaborate on this, how can I do this in Server Class?? I have really no ideas..(I am a not really experienced in rails) > Failing that I;d have the conn_pool thingy be an instance variable of > the Server class with an accessor (so you could do Server.conn_pool > [...]).

[Rails] page.replace_html and
Hello,
I have a page with a form and a div area that I update after submitting
the form.
I want to replace the Div area with new information.
In the page, inside the div area, I have:
<%= render :partial => "list" %>
as I want to show the current records the first time the page opens.
The problem is after submitting, I the 'old values' of the Div remain in
the Div, and now I have the new values with the old values. If I
continue to add some new values, I get always on top the new ones and
after the 'old ones', I get TWO tables, the new one and the old one.
How I can remove the old table
If for example I add some text on the top of the _list (partial included
in the Div), this text gets removed but NOT the table.
Any ideas ?
I'm updating the div with a .js.rjs file:
page.replace_html("div_listd", :partial => "list")
If in the page I don't put the <%= render :partial => "list" %>, I
don't see the inital records (correct), and subsequent forms submitted
show the resulted records ok, so the .js can replace the content of the
Div area ...
very strange for me ...
thanks,
r.

[Rails] Re: Write checkbox values in database
Hi Aaron,
Thanks for your precious time.
I tried your suggestion too. I think i am doing some relationship
mistake between models. I am not sure whether i am doing it in the right
way. I will try to explain what i have done.
Kindly give me whether i am right or whether i am on the wrong way.
I have a models called Child.rb, Childcategory.rb and Filtercategory.rb
The relationships are as given below
class Child < ActiveRecord::Base
belongs_to :user
has_many :childcategories
has_many :timelimits
end
class Childcategory < ActiveRecord::Base
has_and_belongs_to_many :filtercategories
end
class Filtercategory < ActiveRecord::Base
end
NOw i have list of category names in Filtercategories table. I am
listing them using checkboxes in the child view and trying to write them
in Childcategories table if checked by the user.
i.e. app/views/children/show.html.erb
<% remote_form_for [...@child, Childcategory.new] do |f| %>
<%= f.label :body, " Allowed Categories " %>
<% for category in @cat %>
<%= check_box_tag 'child_category[category_ids][]', category.id %>
<%= category.categoryname %>
<% end %>
<%= f.submit "Update Settings" %>
<% end %>
The controller of Childcategories is as below.
class ChildcategoriesController < ApplicationController
def create
@child = Child.find(params[:child_id])
@catlist = @child.childcategories.create!(params[:childcategory])
respond_to do |format|
format.html { redirect_to @child }
format.js
end
end
end
Hence i have written the code in this manner. But the table is not
updated with categories checked by the user. Only childid is inserted
and new record is created without category name and id.
Kindly help me in this regard.It will be very supportive.
Thanks for any help,
Swarna

[Rails] Sessions do not update created_at column?
Hi All, I added a column to the sessions table called "created_at" in order to allow the created time to be recorded. However, different from other Models, the column does not update automatically. Therefore, what codes should I add to update the sessions."created_at" value? It is important for avoiding hacker keeping the sessions alive. Thanks much!

Why not just do "Keys".constantize (will will return the Keys class) ,
ie
foo.constantize.connection.execute 'bla bla bla" since it seems that
the objects in your hash are just the corresponding ActiveRecord
classes ?
Failing that I;d have the conn_pool thingy be an instance variable of
the Server class with an accessor (so you could do Server.conn_pool
[...]). This all looks a little strange though.
