When looking for the best way to make default values, I’ve found that you shouldn’t rely on the DB for these. So in order to integrate these on your Model, I usually follow the next best practive:<\/p>\n\n

\u00a0\u00a0\u00a0\u00a0after_initialize<\/span> :init<\/span><\/div>

After creating the custom input on Part 1<\/a>, we now needed to include a custom getter for each of these inputs. We could set up a method for each input inside our model but that wouldn’t be as cool, so we create a gem with the following behavior:\n<\/p>\n\n
\nObject.instance_eval do \n   def check_for_check( *attrs )\n       attrs.each do | attr |\n           self.class_eval %Q{\n                def #{attr}\n                    #{attr}_check ? read_attribute(:#{attr}) : 0\n                end\n           }\n       end\n   end\nend\n<\/pre>\n\n

After jumping the wagon with Twitter Bootstrap<\/a> for a new client app we are working on, I found myself in to some problem trying to implement this type of input:\n\nWe only have one input let’s say name<\/b> and we wan’t to validate it’s presence when the check is true. The check is a virtual attribute named name_check<\/b>. So using simple_form<\/a> gem for this form.\n\nWe need to create the custom input element first, we do this by creating an inputs<\/b> folder under the app<\/b> folder.

<\/div><\/pre>\n\nThe input will include an option for tooltip, it will automatically append ‘_check’ to the name of the input to create the check box element, the text field with all the regular HTML options and a help line under it.\n\nThis will be how we call it under our views:\n

[<\/span>404<\/span>,<\/span> {<\/span>“Content-Type”<\/span> =><\/span> “text\/html”<\/span>},<\/span> [<\/span>“Not Found”<\/span>]]<\/span><\/span><\/p>\n
in to<\/p>\n
[<\/span>404<\/span>,<\/span> {<\/span>“Content-Type”<\/span> =><\/span> “text\/html”<\/span>,<\/span> “X-Cascade”<\/span> =><\/span> “pass”<\/span>},<\/span> [<\/span>“Not Found”<\/span>]]<\/span><\/span><\/p>\n
This\u00a0”X-Cascade” => “pass” allows for the call to keep going through your routes and see if any other catches this call.<\/p>\n
