== How to handle arrays on HAML == |
|||
When printing an array with the `collect` method, if is evaluating in the header where "-" can be matched or a property in the form "name:" the result will print a `0000` at the end, because obviously the string in question es evaluated and added to the end. In order to avoid this string, add the method `reject` to the end, so if it found one of the above matched characters/strings, it won't be displayed and then `0000` won't be displayed. |
