similar to: If-Else Conditionals in Views

I have some embedded tables that form different sections of a view. I find that I use the same look for certain ones which means I have to duplicate the same exact table for each section that''s similar. Is there a way to do.. hmm.. well.. kind of like what a layout does using @content_for_layout, but for a partial. Does that make any sense whatsoever? :) OK so here''s some

Hi, Just got my first Mac. I''m trying to install rails on it, using the instructions in the rails wiki: http://wiki.rubyonrails.com/rails/pages/HowtoInstallOnOSXTigerUsingDarwinPorts I go to install mysql, and the version of mysql supported by DarwinPorts appears to be 4.1.18. But all the sites appear to only have 4.1.19 or 4.1.20. So it looks like DarwinPorts is over a month out

Hi all, There''s a dead thread about this back at http://forums.sun.com/thread.jspa?threadID=5075157, but it would be really nice to have support for if/else control flow in actions. Reasons: 1. The ternary operator ?: is already there (though it doesn''t let you do anything with side effects) 2. The user can already write arbitrary and expensive non-cacheable predicates if

Hi, Is there some way to produce an anchor that looks like the following using helpers, or should I just code it in the rhtml like this? <a href="#" onmousedown="javascript:foo(); return false"> Thanks, Brad -- Bradley Mazurek

I am confused about the @content_for_layout.''cause it will display all the views in the layout.Do I have any methods to let the layout be more OO? I mean that for example,the app currently have more than one views to be displayed,but only some of them to be displayed at the same time at different <div></div> units. I hope there exists a kind of way that: <%= if

What does the Magic Field Name position do? I was looking here: http://wiki.rubyonrails.com/rails/pages/MagicFieldNames And unfortunately that documentation is incomplete. Thanks. -- Posted via http://www.ruby-forum.com/.

I''m trying to marshal some information I have in Javascript, and send it over an AJAX request to the server, specifically to be stored in a model on the server side. I have some Javascript routines I wrote that gather information about the user selection. I see that the link_to_remote has a :before option in which I can write Javascript to collect what I need, but right now I''m

Hi, I haven''t done any associations before, so please forgive my incorrect use of terminology... If I set up a has_many :through association, can I manipulate the associated instances directly (like an Array), or do I need to manipulate the join model? For example, suppose I have two classes and the associated join model: class foo has_many :foo_bars has_many :bars, :through

How can I pass something to set_table_name so that I can switch tables on the fly for accessing archive data? If I could access sessions inside a model I would do something like: if @session[:current_period] set_table_name "statistics_" + @session[:archive_year] else set_table_name "statistics_" + Date.now.year end But since I cannot access the session from within a

I''m going to take another stab at this question (my first one received no replies): I have two models: Author has_many: books Book has_one: author I have two tables: authors id ... books id author_id ... I let the scaffolding fly and it created the CRUD goodness for each model, as expected. However, I want to have only one view/controller "set" for both models; when I

I''m researching generating PDF files via RoR. I see there are packages available to do this. One such package is the PDF-Writer. The examples I saw for this package save the PDF to a file. Is there a way I can output the PDF on-the-fly to the browser rather than having a temporary PDF file? I just can''t have these files laying around since they contain sensitive

Colin, If your propose is to create a ternary plot with points and vectors, I think easier do this with graphics based plots instead of trellis based plots. Although, with little work you can do with trellis too. I gave you a reproducible code to put an arrow in a ternary plot. I use the function locator() to extract coordinates. The code is the following

I'm in e-mail contact with a geochemist who maintains a well regarded geochemistry web site. He's drawing diagrams either with a Turbo Pascal program running in a DOS window or with Excel. I'm trying to persuade him that R would be a better choice. Something he's particularly keen on is ternary diagrams. I think he is talking about ternary phase diagrams, and if so, it looks as

Hi, I am trying to create a triangular plot to show the 'composition' of a set of items with three variables (historically the percent sand, silt and clay in soil). So far I have tried the 'soil texture triangle plot' in the package plotrix and the 'ternary or triangular plots' in the package cwhtool (cwhmisc). Both have strengths and weaknesses, but neither has a
