我已使用以下代码段定义了一个脚本:
check_params param
def check_params(param)
# some code
end
当我跑步时,我得到了
主要的未定义方法`check_params':对象(NoMethodError)
答案 0 :(得分:14)
Ruby希望在调用方法之前声明方法,在调用方法之前尝试移动方法定义:
.clearfix:before, .clearfix:after {content: " "; display: table;}
.clearfix:after {clear: both;}
.clearfix { *zoom: 1;}
.large-icon-list {
margin-top: 5em; border-bottom: 1px solid #eee;
margin-left: 8.54701%; margin-right: 8.54701%;
}
.large-icon-list li {
min-height: 170px; width: 48.71795%;
float: left; margin-right: 2.5641%;
display: inline;
}
/* one class-rule for each image - here sheets */
.large-icon-list li.icon-list-sheets .icon-list-image {
background: url("../icon-sheets.png?14....9")
no-repeat top center;
}
.large-icon-list li .icon-list-image {
height: 100px; width: 23.07692%;
float: left; margin-right: 2.5641%;
display: inline;
}
.large-icon-list li .icon-list-content {
width: 74.35897%; float: right;
margin-right: 0; *margin-left: -30px;
display: inline;
}
