I tried something like: element.highlight(flash[:notice]) without any

I have a method that returns either a comment stored in the flash (if it exists) or a new comment. It works when I put it in my application controller: def preform_comment if flash[:badcomment].nil? comment = Comment.new return comment else return flash[:badcomment] end end However it would be cleaner to put this in the Comment model, so I tried: def

I''ve discovered something very odd about the way Rails is handling Flash media. I am attempting to load a partial that contains the code for a flash adverstisment for the website. It was working ok when the code was in the page, but once I pulled it out to a partial (so I could use it on other pages) it stopped working. <%= render(:partial =>

I''m a belgian Rails user (Dutch is my native language). I wondered if it is possible to translate error messages (generated by validators). I know how to create my own error messages: def method content rescue logger.error(...) flash[:notice] = ''My own error message" redirect_to(...) But where can I find the validator''s .rb files, so I can change them?

Hiall, Unfortunately I just can''t find out how to setup a default selected value when using collection_select. My call is like so: <%= collection_select(:consultant, :lastname, @consultants, :id, :lastname, { :selected => @current_consultant.id } ) %> which is not working, I debugged so far that I know that @current_consultant.id contains the correct value. Any tips? cheers

Hi there, I''ve been trying to paginate over a list of members that all share a tag in common using the acts_as_taggable plugin. The regular way of paginating over a collection doesn''t seem to work with acts_as_taggable. Here''s what my method looks like that takes in a tag name, finds all the members that share the tag and then displays all the members. Nothing too fancy

I''m just learning Rails and have encountered a problem trying to set a field in a DB record based on the value of another form input field. Using the scaffold code, the create works as expected and the update (edit) also works. However, one of the DB fields (amount) is supposed to be computer from another (units): if the category field is "Mileage", amount= units *

Hi, I''m using scriptaculous to provide an auto complete textbox - and it works perfectly - but I was wondering if there was anyway to let users navigate the choices using the keyboard i.e the curor keys as opposed to having to use the mouse? Apart from that it''s perfect! :) Cheers, Pete -- Posted via http://www.ruby-forum.com/.

I would like to create a rock solid asterisk server that comes up no matter what. Ofcourse I can consider hardware raid1 but.... for the cost of a hardware raid controller I can also buy a 2GB compact flash card that doesn't produce any heat or noise and is friendly to the electricity bill and our environment :) 2GB is more than sufficient for a linux distro and an * installation but

hi, i have a situation where i have a list of options from which a user selects his options if its not in the list he/she selects Others/Not Present and a new textfield should pop up and the data entered there should be considered instead of dropdown. i have done this using javascript/dhtml but i was wondering how this can be done using pure rails i.e using some of the RoR apis?. i would

I''ve scoured the Wiki and gone through the documentation with a fine toothed comb, but I can''t seem to find this answer. I want to keep a history of the changes made to a record, but can''t seem to find out what fields have changed. I''m sitting in the update function, as you can see below...

Hi, I have the following problem that I can''t seem to figure out. I want to able to fetch some text from my database record in my controller, and then add two links within the text and then send that back to the view to get rendered so that the two links appear as links and when clicked on, they''d basically call the corresponding action for the link.

Rails has many built in validation methods to ensure that an ActiveRecord instance cannot be created or updated under certain situations (typically caused by invalid data). However, I can find no methods to govern whether an ActiveRecord instance can be destroyed. Essentially, I wish an error to be raised when a user tries to delete an ActiveRecord without first adhering to a certain set of

Hi, I am looking for ideas on how to remove the last item from a paginated page when a new item is inserted, thus leaving only 10 elements on the page. Currently I have a form that inserts with AJAX, but as expected, each post added to the page just increases the number of posts leaving 11 on a page that should only be displaying 10. I have unique ID''s for each post (e.g.

Is there some standard way to test migrations? It seems to me that an additional safeguard for migrations would be to test and see if applying the migrations to the test database allows one to reconstruct the structure of the development database. If you can''t, then there is an error in your migrations, most likely because someone hand-modified the database without generating a
