使用 like 子句和 foreign-key/belongs-to 子句的 GORM 查询有问题

Question

Groovy 版本 2.4.8 Grails 版本 2.5.1

我正在尝试使用 like 子句从我的顾问 table 中提取行，而且如果方法中传递了公司名称，那么我只想从该公司中提取顾问。

我构建了两个查询，其中一个没有 Firm 组件，它工作正常，但是当我取消注释设置公司的行以测试第二个查询运行时，我得到以下异常

org.springframework.orm.hibernate4.HibernateQueryException: Not all named parameters have been set: [firm] [from Advisor a where lower(a.firstName) like:keystrokes OR lower(a.lastName) like:keystrokes AND a.firm.name = :firm];

代码：

def getAdvisorsForKeystrokes(String keystrokes, String firm, int maxResults) {
    List<Advisor> advisors;
    firm = "Test Firm Name"
    if(firm.allWhitespace) {
        advisors = Advisor.findAll('from Advisor a where lower(a.firstName) like:keystrokes OR lower(a.lastName) like:keystrokes', [keystrokes:keystrokes + '%'], [max:maxResults])
    } else {
        advisors = Advisor.findAll('from Advisor a where lower(a.firstName) like:keystrokes OR lower(a.lastName) like:keystrokes AND a.firm.name = :firm', [keystrokes:keystrokes + '%'], [firm:firm], [max:maxResults])
    }

    return advisors
}

类:

class Advisor {
    String firstName
    String lastName
    String fullName
    String city
    String state
    Firm firm
    static belongsTo = [Case, Firm]
    static hasMany = [cases:Case]
    static constraints = {
    }
}


class Firm {
    String name
    static constraints = {
    }
}

如果任何人对问题是什么有任何想法或一个很好的解决方案，谢谢！

编辑：

我知道它可以像下面这样重写并且可以工作，但我在一个查询中尝试了很多不同的方法，但我一直没能找到一种方法让它工作，这很麻烦。

def getAdvisorsForKeystrokes(String keystrokes, String firm, int maxResults) {
    List<Advisor> advisors;
    advisors = Advisor.findAll('from Advisor a where lower(a.firstName) like:keystrokes OR lower(a.lastName) like:keystrokes', [keystrokes:keystrokes + '%'], [max:maxResults])
    if(!firm.allWhitespace) {
        def firmModel = Firm.findByName(firm)
        advisors = advisors.findAll{ adv ->
            adv.firm == firmModel
        }
    }

    return advisors
}

你应该在同一个映射中设置两个参数，像这样：

advisors = Advisor.findAll('from Advisor a where lower(a.firstName) like:keystrokes OR lower(a.lastName) like:keystrokes AND a.firm.name = :firm', [keystrokes:keystrokes + '%', firm:firm], [max:maxResults])

使用 like 子句和 foreign-key/belongs-to 子句的 GORM 查询有问题
