If I do validates_uniqueness_of :name, :message => "It''s not uniqueeee!!!" then how do I have it display that message when the check fails? -Ben Lisbakken -- Posted via http://www.ruby-forum.com/.
Check the API for ActiveRecord::Errors and error_messages_for.

That''s how I''ll display the message... but I''m referring to the parameter :message in a validates_uniqueness_of line. How do I access that after the test fails? -- Posted via http://www.ruby-forum.com/.

<%= error_messages_for(''my_model'') %> in your view.
Some css style examples:
154 /* error
155 ---- */
156 .fieldWithErrors {
157 padding: 1px;
158 background-color: red;
159 display: table;
160 }
161 #errorExplanation {
162 border: 2px solid red;
163 padding: 7px;
164 padding-bottom: 12px;
165 margin-bottom: 10px;
166 background-color: #f0f0f0;
167 }
168 #errorExplanation h2 {
169 text-align: left;
170 font-weight: bold;
171 padding: 5px 5px 5px 15px;
172 margin: -7px;
173 background-color: #c00;
174 color: #fff;
175 }
176 #errorExplanation p {
177 color: #333;
178 margin-bottom: 0;
179 padding: 5px;
180 }
181 #errorExplanation ul li {
182 list-style: square;
183 }

Wanted the error message in my controller, not the view. here''s how I did it @messages = @user.errors.full_messages flash[:notice] = @messages[0] for i in (1..@messages.length-1) flash[:notice] += "<br>" + @messages[i] end -- Posted via http://www.ruby-forum.com/.

Or even just errors[:field] As for you example code is there a reason why you couldn''t just use something like flash[:notice] = @user.errors.full_messages.join("<br/>") The error_messages_for will provide you with a display in your view of all these messages, and there is a post from Jean-etienne Durand with an example style. If you don''t want to display some of the portions of what is returned from error_messages_for why not control it with CSS. eg errorExplaination h2 { display:none; } errorExplaination p { display:none; } Just my 2c -------------- next part -------------- An HTML attachment was scrubbed...
