Interesting Things

• Another IE6 issue: CSS selectors. A div can have multiple classes, such as <div class="grey box"></div>, and there are multiple CSS selectors for this, only one of which works with IE6:

<code>
/* Works fine with IE6 */
.grey .box {
    border: 1px solid black;
}

/* DOES NOT WORK with IE6 */
.grey.box { /* Note the lack of space! */
    border: 1px solid black;
}
</code>

• In Rails, It is possible to declare a “white list” and a “black list” of attributes that can be mass-assigned in an ActiveRecord model: Note that these cannot both be used in the same class!
  • attr_accessible (white list) – only attributes in this list can be mass-assigned.
  • attr_protected (black list) – as long as an attribute is not in this list, it can be mass-assigned.
• Rspec redirect assertions now work! Use this in your controller specs:

<code>
response.should redirect_to(:controller => "my_controller", :action => :an_action)
</code>

• alias_method_chain is an extremely handy new method in Rails, which encapulates a common pattern. Much of Rails and appable_plugins is built on this.
• And most importantly: Taqueria Cancun now has carnitas!!!.

• Has anyone had problems with IE6 failing to send Ajax requests?
