I''ve gone once through the Agile book and am now attempting my own rails app. I''ve created a table named ''volunteers'' with over 15 columns. The problem is the default list.rhtml that is created with the scaffold, shows all the columns. I only want to show 4 of them with the list view. Where would I start to only return a handfull of columns to the

In a standard scaffold generator, the list.rhtml looks something like this ... <% for column in Book.content_columns %> <th><%= column.human_name %></th> <% end %> How can I modify this code so for each table column add my own name not the "human_name" generated code? -- Posted via http://www.ruby-forum.com/.

My code executes fully: <% for column in ModelName.content_columns %> <th><%= column.human_name %></th> <% end %> but it does not pick up any columns in my model''s table that end in "_id". Is this by design? Is there a helper method that will reference the related tables? Or will I need to code the column titles and detail records by

I''m studying the Agile Development with Rails book. In the chapter that first sets up the depot application (page 68), there is this bit of code from a view: <% for product in @products %> <tr> <% for column in Product.content_columns %> <td><%=h product.send(column.name) %></td> <% end %> etc... I am trying to absorb both Ruby and

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

Hi, I''m a newcomer to Ruby and to Rails, and am having a problem with character encoding. Now, I know ruby doesn''t handle unicode...but, characters like ? (eacute) and ? (ccedil) are part of the iso-8859-1 charset, so it shouldn''t be a problem, right? But, for some reason, the string functions still seem to hang on those characters. As an example, in a brand new rails

I have two tables CREATE TABLE continents ( id int(11) NOT NULL auto_increment, name varchar(255) NOT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; CREATE TABLE countries ( id int(11) NOT NULL auto_increment, name varchar(255) NOT NULL, continent_id int(11) NOT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; I generate scaffolds for country and for

Hi, I''ve just been pleasantly surprised, again, by how much Rails does for me, but I am *really* surprised. Surprised as in "how the heck did that happen?" I''d really like to understand this and would appreciate any help. Big picture... the user is presented with a form that allows them to select one or more check boxes to record their allergies. The form uses the

After messing around with PHP for over a year, I took one look at Ruby on Rails and fell in love. But it''s one of those confused "Men are from Mars, Women are from Venus" type things... I''ve written a method which does find_by_sql to pick a random row from a database. When I call that method I get an "undefined method ''text'' for ..."

This is the default scaffolding for list.rhtml: [code] <h1>Listing <%= @scaffold_plural_name %></h1> <table> <tr> <% for column in @scaffold_class.content_columns %> <th><%= column.human_name %></th> <% end %> </tr> <% for entry in instance_variable_get("@#{@scaffold_plural_name}") %> <tr> <% for

One more question: Is there some way to set the human_name of a column? e.g.: human_name for column address1 shouldn''t be Address1 but "Address, line 1". If not, should I make a hash with my custom names?

Hi all, I''m trying to build a routine that generates table rows with the appropriate field types (text_area and text_field for now), and filters out the ''created_at'' and ''deleted_at''. <% for column in Project.content_columns %> <tr class="ListLine<%= cycle("0","1") %>"> <td><%=

Hi all, I''m searching for a method to dynamically build a form. ( false/true field in the DB should automatically be a droplist) If you use "_form.rhtml" it works easy, with only this code in your partial, but uses the extra file, and doesn''t feel profi and flexible. <%= start_form_tag :action => ''create_product'' %> <%= render

Hello, I am having some trouble figuring out how to use the rateable plugin. i followed as close as the directions located at http://www.naffis.com/blog/articles/2006/08/31/rails-ajax-star-rating-system but i fail at working it. i am getting this error You have a nil object when you didn''t expect it!

i''ve got a cool app going and it''s getting bigger and bigger, but now i''m trying to customize the show function. i''m using the scaffold code as a base but can''t seem to get anything to look right. i guess i''m confused about how exactly the scaffold code works for the "show" function. any help would be awesome! thanks. jon --

Hi Leif, Did You faced that with the exact same Chrome version? Since this version is the only one having this issue. I have had this kind of arrangement (intro + live stream) for decades. Technology changes but the idea is the same. I have tested a lot of hardware and combinations. I do have a fail over stream (with different specs) and that hasn’t been an issue at all. I do not know but I

Hi there, Any other versions of Google Chrome and all version of other browsers are working. I have done my best to set up the intro to match the live stream. http://185.139.168.34:8000/yleisohjelma - intro is 256 kbits/s 48 kHz ISO-MPEG2 L3 - live is 256 kbits/s 48 kHz ISO-MPEG2 L3 http://185.139.168.34:8000/vara - live is 128 kBits/s 48 kHz, possible ISO-MPEG2 L3 - there is no intro Of

Let's say I have a data.frame like A B C TS other columns 1 1 1 12345 1 1 1 56789 1 2 1 23456 1 2 2 23457 2 4 7 23458 2 4 7 34567 2 4 7 45678 and I want the last row for each unique combination of A/B/C, where by "last" I mean greatest TS. A B C TS other columns 1 1 1 56789 1 2 1 23456 1 2 2 23457 2 4 7 45678 I did this simply in SAS: proc sort data=DF; by A B C descending TS
