希望可以支持一下JSONQuery("key").NotEquals(...)

[siriusa51]

我尝试着复制JSONQuery代码自己修改NotEquals，发现gorm框架里面有各种各样的类型限制，导致我没法直接设计自己的NotEquals 所以希望架构能支持JSONQuery.NotEquals, 或者说至少支持我自定义实现JSONQuery等部类型的相关Condition接口

func exprToCondition(exprs ...clause.Expression) []Condition {
    conds := make([]Condition, 0, len(exprs))
    for _, e := range exprs {
        switch e := e.(type) {
        case *datatypes.JSONQueryExpression, *datatypes.JSONOverlapsExpression:
            conds = append(conds, &condContainer{value: e})
        default:
            conds = append(conds, &condContainer{err: fmt.Errorf("unsupported Expression %T to converted to Condition", e)})
        }
    }
    return conds
}

func condToExpression(conds []Condition) ([]clause.Expression, error) {
    if len(conds) == 0 {
        return nil, nil
    }
    exprs := make([]clause.Expression, 0, len(conds))
    for _, cond := range conds {
        if cond == nil {
            continue
        }
        if err := cond.CondError(); err != nil {
            return nil, err
        }

        switch cond.(type) {
        case *condContainer, field.Expr, SubQuery:
        default:
            return nil, fmt.Errorf("unsupported condition: %+v", cond)
        }

        switch e := cond.BeCond().(type) {
        case []clause.Expression:
            exprs = append(exprs, e...)
        case clause.Expression:
            exprs = append(exprs, e)
        }
    }
    return exprs, nil
}
