Question

我正在开展一个用户应该输入电话号码的小项目，所以我想使用“ClientSideValidations”gem来验证这些信息。

validates_format_of :telcasa, :celular, :tel_flia, :tel_trab, :tel_ref_2, :tel_ref_1, 
    length: { in: 10 },
    :with => /\A(\d{10}|\(?\d{3}\)?[-. ]\d{3}[-.]\d{4})\z/,
    :message => "Formato invalido"

但是，对于将要使用该项目的区域，我必须验证对应于区号的电话的三个第一个号码（“809”/“829”/“849”）。如何验证用户是否使用三个区号之一正确键入了电话号码？

Answer 1

将/\A(\d{10}|\(?\d{3}\)?[-. ]\d{3}[-.]\d{4})\z/更改为：

/\A(\(?(809|829|849)\)?[-. ]\d{3}[-.]\d{4})\z/

我冒昧地放弃了你匹配任何十位数字的部分 - 不确定它为什么存在或如何在你的环境中使用它。

您可以编写一些自定义验证

#include <stdio.h>

struct entry
{
    char    word[15];
    char    definition[50];
};
struct entry dictionary[100] = 
  { {"boy",         "a boy          "                   },
    {"aardvark",    "a burrowing African mammal"        },
    {"acumen",      "mentally sharp; keen"              },
    {"addle",       "to become confused"                },
    {"cat",         "a cat"                             },
    {"affix",       "to append; attach"                 },
    {"agar",        "a jelly made from seaweed"         },
    {"ahoy",        "a nautical call of greeting"       },
    {"aigrette",    "an ornamental cluster of feathers" },
    {"ajar",        "partially opened"                  } 
  };



int main(void)
{
    int i;
    void dictionarySort(struct entry dictionary[]);

    dictionarySort(dictionary);

    for(i = 0; i < 10; ++i)
    {
        printf("%s\n", dictionary[i].word);
    }

    return 0;
}

void dictionarySort(struct entry dictionary[])
{
    int i, k, j;
    struct entry temp[100];

    for(i = 0; i <=  9; ++i)
    {
        for( k = 0; dictionary[i].word[k] != '\0'; ++k)
        {
            if( (dictionary[i].word[k] > dictionary[i+1].word[k] ) )
            {
                temp[i] = dictionary[i];
                dictionary[i] = dictionary[i+1];
                dictionary[i+1] = temp[i];
            }

        }

    }
}

或者，如果您愿意，可以在函数validate do valid_phone_codes = [ "007", "042", ...] valid_phone_codes.each do |valid_code| # Also handle optional parenthesis return true if self.phone_number.starts_with?(valid_code, "(#{valid_code})") end errors.add(:phone_numbers, "Must start with a valid country code (one of #{valid_phone_codes.join(', ')}") false end中声明此代码，然后添加一行

def valid_country_codes
