similar to: Scaffolding, DRY and RHTML

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

Hi, Very new to RoR; have been a flash developer for four years or so. I have an urgent question -- in the list.rhtml file, I only want to display certain columns instead of dumping out all the columns in the database. Could someone shed some light this topic? Thanks!!!

Hello everyone! Ive been on rails for the last month or so and really enjoyed this framework. However its very hard to find documentation on how to do things right! For example every beginner after a while realizes that having similar CRUD actions in every controller and views for them is not DRY at all! Few days ago I found http://dereksivers.com/rails-shared-controller.html I quite like his

HI all, I"m using 1.1.6 script/generate scaffolding. Why does the view/foos/list.rhtml use "foo.send(column.name)" to display the contents of each column? I had to change this to "foo[column.name]" to get the display right in a couple of models. Specifically, one model has a column named ''display'', is that conflicting with something internally to AR ?

Hi all, I''ve got an odd issue. I''m new to Ruby/Rails and have a bit of a silly question. I''m following along with the nice little tutorial here, to get an idea of the system: http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html?page=3 However, I''m running into an issue where the author adds a new field in his database, refreshes the browser and shows

I created some scaffolding for an Address model and an Addresses controller. When running the functional tests for the addresses controller, I get this exception: "NameError: uninitialized constant Addres" The exception seems to start from this function: def list @address_pages, @addresses = paginate :address, :per_page => 10 end I''m guessing pluralization bug?

If I do: script/generate controller Photo I get a controller named photo_controller. OTOH, if I do: script/generate scaffold Photo I get a controller named photos_controller. (Note that the controller name is pluralized). I realize that I''m specifying the controller name explicitly in the first case, but it seems odd to me that the scaffold command generates a pluralized

Hi all, I''m building my first Rails app. Please forgive my ignorance as I get acquainted with the technology. What I''d like to do is have a form that the scaffolding created for me appear on my home page. It''s just one text field, a submit button, and some error messages. I first tried to copy the code from the new.rhtml view into the homepage (index.html), then

First, thanks to everyone who replied to my pluralization question from before! Today I was trying to do what I think is called a "chained accessor". I have an "events" table and each event has one user. Instead of seeing the id number for each event''s user, I''d rather display the names of users instead. I tried to do this: class Event <

Hello, i''m new in ruby rails framework. I have the following problem. I try to create a scaffold for a certain model of my db, but since ruby rails doesn''t assume the table name corectly (its incidents_reported ) i get errors .... Besides renaming the table :) is there a way to ''tell'' ruby rails the name of the table? I haven''t been able to find any

I am having trouble generating some of my scaffolding. I''m trying to use PostgreSQL as my back-end. Some of my scaffolding generates with no problem but for other parts I get this: Before updating scaffolding from new DB schema, try creating a table for your model The tables do exist. At least I can see them from psql. Here is the SQL I''m using to create my tables: CREATE

Hi all, Not sure if Im doing this the right way (most likely not as I cant make it work!) I have an application that needs to put some content from two different tables(db) on every page within the application. What I thought I could do is write a small application helper that talks to the model and asks for the data. But I cant for the life of me work out how to actually talk to a model from

Railers: Greetings from the low end of the learning curve. I have installed all the prerequisites on Win32, including a lite MySQL database with a table in it called Inventory. Then I run this command line... ruby script/generate ajax_scaffold Inventory ...and I get this error message: error Before updating scaffolding from new DB schema, try creating a table for your model

I am a newbie Ruby and RoR user. In my tests using the turorials that I found over the web, everthing is working fine and I am very impressed about RoR framework. As I am a Delphi developer, without any web development experience, There is some thing hard to understando and I didn''t find a tutorial about this. I wonder how to create a non-scaffold page ? I have customers,

I have a shopping cart function, and I''d like to set it up to update the cart with AJAX. My AJAX call will return a view that displays the cart items. My question is with regards to keeping things DRY. When the user goes to "view cart", that page needs to display the cart, then the cart display needs to update with AJAX calls when items are added from that page. It would

Like with simple table editing, there are also typical ways of how a user usually interacts with one-to-many or many-to-many relations. For example, one would show the fields of one row of table1 in the screen and below a line-by-line view of all associated entries in table2. Then, one could press an "Edit" button and add or delete rows from table2 to this entry of table1,

I''ve created several different Rails applications but I''m running into the same trouble with each one. Lets say I create an app called Test. I type ''rails test'' and it generates the directory for me. Now I edit my database.yml file. Then I create a database with Postgresql by typing createdb test. Now I go into Postgresql by typing ''psql

I am a newbie, but have worked through 4 or 5 tutorials. I am using InstantRails. The problem is that I cannot determine how the style is being included. I have modified the stylesheet from /public/stylesheets/, even removed it. All to no avail. The inline <style>...</style> code is still being included from somwhere. Where? What am I missing? thanks, steve -- Posted via

Hi all, I have defined the following method in both application.rb and application_helper.rb: def still_logged_in? !session[:user_id].nil? end This method is called in a before_filter in my application.rb, as well as in my layout/application.rhtml and view/user/login.rhtml (for showing a login / logout button, etc.) I had to put it both places, otherwise I would get an
