Hello, I wrote a function create_report that calls the function Sweave. create_report shall be used to create a pdf-report about an lm-Object which is passed as an argument to create_report.

People, In the cookbook eg, categories has_many recipes but in a book eg, book has_one description - doesn''t that mean that the id of the description should be the same as the id of the book (instead of having it''s own "description_id" in the book table?

Hola, parece que el problema está relacionado con la versión de Pandoc. La última da problemas, según parece: https://github.com/boxuancui/DataExplorer/issues/119 DataExplorer failed on the iris and mtcars data.frames on 3 of 4 computers today. It took hours, but the problem seems related to newer versions of Pandoc. Only Pandoc 2.6 works with DataExplorer. It will fail with newer versions 2.7

Most of my machines are pretty cookie-cutter, so I have one class and config file setup for different services. For example, pretty much have one hosts.allow that goes out everywhere. However, there are always exceptions. So I have 3 hosts that have similar configs but have more things open, so what''s the ''best practice'' way to centralize those? Do I really need to

Hi, We are building a rails application that''s sort of a CRM + room/course booking. Among other things, it provides a centralized database of all the people the company has been in contact with. We want to provide the possibility of sending customized email messages to groups of contacts, for example a newsletter to 500 people starting with "Hi [:name:]". The naive approach

I have been going around on the Internet about this all day and found absolutely nothing that seems to fit this problem. I have a mailer named "Notifier" -- in fact I have been using the EXACT code from the "Agile Development With Rails" chapter on "Sending E-Mail", pp. 411-416, except for my names (mailer named "Notifier", emailer method named

I want to build an application that has the concept of administrative domains. What I mean by this is that administrators have access to different data, based on what domains they are a member of. The domain strucutre is hierarchical. Here is an example: - MLB - AL - East - Yankees - Red Sox ... + Central + West - NL + East + Central + West Now

All, Is it possible for a view to call back to a controller method? If so, what is the syntax? === details I have a list view that I want to filter out inactive rows based on several table fields being zero, old, etc. It would seem I should create a "filtered" method in the controller (which I have done). Then invoke if from the view like: for row in @rows continue if row.filtered

I have a cronjob that runs "ruby script/runner ''Channel.preload''". Channel is a parent model, Item is the child model (i.e., Channel has_many :items and Item belongs_to :channel). The coupling is minimized, the coherence looks good, but I''m not sure the model is the right place to put this code. Is there a better place to put this code, e.g., a component (I

Hi, I am a newby in rails...and i have read that scruffy is a great tool to create/display images. Now i find the code below for example... graph = Scruffy::Graph.new graph.title = "Comparative Agent Performance" graph.value_formatter = Scruffy::Formatters::Percentage.new(:precision => 0) graph.add :stacked do |stacked| stacked.add :bar, ''Jack'', [30, 60, 49, 29,

I''m trying to track down why I''m getting close to desired output, but not quite. It looks like the webpage sorta-kinda is grabbing the right data. For instance, there are three Login objects which should be showing and it looks like the show is grabbing three objects, so that fits, to a degree. However, it''s just grabbing the hexadecimal object id, and not

Just wondering how to best integrate with pagination and still stick to MVC... Say I have a Post model that has a published attribute. I want to show all the recent published posts on a page. My first instinct is to create a method in the Post model called recent that does the find with proper conditions and order, but the problem I have is how do I use that with pagination (which definitely

Should I create a separate controller for each model or should I use 1 controller for all models? Having 1 "admin" controller for all backend stuff seems logic to me, but when I scaffold it rather makes 1 controller per model. I''m fairly new to the MVC pattern, so what''s the prefered way of doing it? I''m also wondering if the API is up to date? When

My directory browsing app shows lists of file. If the item is a folder, show a folder icon and link to the action that shows directory contents. If the item is a graphics file, show a thumbnail and link to a larger view. If the item is a non-graphics file, show an appropriate icon and stream the file if the link is clicked. The controller creates an array of arrays of items in the current folder,

All, I have ordered AWDWR and am anxiously awaiting its arrival. In the meantime I still am playing with ROR using radrails. I have a few questions ...

Hi all, A newbie with Ruby on Rails - and programming in general - I''m working on a few Flash and PHP projects as well. Partly to make my work more efficient, partly to gain a better understanding of system architecture / design patterns, I''ve been trying to use the MVC pattern in database-backed Flash / Actionscript development as well. I think / hope that I''m
