Bil*_*lly 5 syntax haml coffeescript hamlc
我试图在我的一个模板中添加少量逻辑(请不要骂我在视图中放置逻辑的错误)并且很难获得正确的hamlc语法.
我正在迭代一个集合,并希望跳过另一个集合中存在的元素
直接的咖啡因看起来像:
for artwork in artworks
unless _.find(cart_items, (ci) ->
ci.id == artwork.product_code
alert 'artwork not in cart'

我尝试着:
- for artwork in artworks
- unless _.find(cart_items, (ci) -> | # < multiline, right?
ci.id == artwork.product_code
- alert 'artwork not in cart'

有任何想法吗?蒂莉,比利
我可以通过将闭包放在同一行来使其工作:
- for artwork in artworks
- unless _.find(cart_items, (ci) -> ci.id == artwork.id)
- alert 'not in the cart'
