I have an action/view that I need to return only data (other external processes query this action/view) but I need the standard_layout template to be attached to the other actions/views in the same controller. ie, the editing of the data in the model needs to include all the navigation, except one view which should just return a text/plain output. how do I say "include

Ok, this is a hard one and I just thought I''d see if people on the list had any suggestions on how they would approach this, I''ve not started to implement the rails to handle this yet as I''m still at the paper planning phase. I''m building an app that has to handle availability for travel packages. The complexity comes in that a person can choose a start

Hi, I''ve got the following models: Company Package with a habtm relationship. In my controller, I have a ''dispatch'' action which does the following @companies.each do |company| @packages.each do |package| company.packages.push_with_attributes(package, :sent_on => Time.now) end end my table ''companies_packages'' therefore lists which

I''m trying to do, what seems like, a very basic join. However, the association just doesn''t seem to work. I''m sure it''s something very simple but I don''t know what. class Role < ActiveRecord::Base belongs_to :packages belongs_to :users end class Package < ActiveRecord::Base has_many :roles has_many :users, :through => :roles end

This SystemStackError is driving me crazy. It only takes place when testing with WEBrick - I can''t reproduce it with any tests. It is caused by calling the "missing" id method (base.rb:2435) on my ActiveRecord class. WEBrick and my tests are running as the same user, with a `ulimit -s` of 10240. Plus the query works sometimes so I don''t think this matters.

I?m following along a few tutorials on the web and trying to implement my own example, but I must be missing something because I can?t get has_many or belongs_to to work like I expected. now I have watched all the videos and made a cookbook several times with different interfaces. what I''m looking for is *not* a code snippet to solve something (because I already have that),

I''ve demoed my rails app and now have to move it to a MSSQL DB. the big problem I''m running into is the table name conventions I have to use. I have to use names like tbl_Transfer & tbl_User. In my tests on the console, I am trying myvar = tbl_Transfer.find_by_sql("select top 1 * from tbl_Transfer") NameError: undefined local variable or method

I''ve rewritten my kickstart cgi in rails with DB acces to the host list and the testing is perfect. I can send the macaddress in the HTTPrequest Header, rails looks up the macaddr in the machine db and spits back out a kickstart file for the machine.. however in real world usage what I get is a request for http://server//kickstarts/kickme which rails fails with 192.168.20.176 - -

Hi guru''s out there, Im happilly coding my first rails app, and all goes well. I find myself manually coding in a particular field all the time (company_id), that relates the contact to a company. The total coding of this form seems somewhat much. Could somebody tell me what Rails power I''m possibly missing and stuborn as I am trying to do myself? I was wondering if the

I usually use the cross-correlation between the speaker signal and the mic signal. It works pretty well. The problem is the you need enough data in order to get a good S/N. I compute the cross-correlation between 1.5 second data of each signals. In this way the application detection of any anomalies is quite slow. I am looking for something faster, but I fear it will be something very application

1) Everytime a participant speaks there is a echo for a short duration (maybe a word or two) but as the participant continues to speak without a any break the echo is 95% cancelled (i.e there is a feeble echo still present if observed very carefully). 2) The moment the participant stops / pauses speaking and start talking again, scenario 1 is repeated as if the echo state has been re-initialized

Yes. I guessed that too, however I am not sure why it keeps repeating every time the user stops / pauses and starts speaking again in a single session. I am using a laptop with standalone speakers. For echo cancellation to work one has to make sure that the ref and echo buffers are synchronized. I guess this is the most common problem. -Elston -----Original Message----- From: Anton A.

Even reading the documentation I can not figure out what is the select_tag difference between this: <% = select_tag (bags [], "options_for_select (bags.collect @ {| bb | [bb.bag_type, bb.id]}, ruser.bags.collect @ {| ub | ub.id}), {: multiple => true,: id => "bags"})%> and this: <% = select_tag "bags [], " options_for_select (bags.collect @ {| bb
