问题描述
我正在为客户制作一个网站,但我偶然发现了一个问题,我需要一些建议。
I'm making a website for a client but I stumbled upon a problem and I need some advice on it.
对于每个项目,他们希望拥有设置可变数量的图像和(有时)一些相应文本的可能性。
For each project, they want to have the possibility to set a variable amount of images and (sometimes) some corresponding text.
我正在考虑将所有信息存储在一个字段中,而不是将field_1映射到field_99以防万一他们需要99个字段。
I was thinking about storing all of the information in one field, instead of making field_1 to field_99 just in case they need 99 fields.
// database column
'../fotos/foto1.png',
'hier komt tekst',
'../fotos/foto2.png',
'', (empty text)
'../fotos/foto3.png'
此解决方案有一些不利之处,必须有更好的方式实现这一点。
This solution has some disadvantadges, there must be better manners out there to achieve this.
这样做的首选方法是什么?
What's the preferred way to do this?
推荐答案
创建另一个表(例如FOTO_CODES),其中包含所有可能的foto值,并为其生成id
Create another table (e.g. FOTO_CODES) with all possibly values of foto and generate id for them.
创建另一个子表,它将具有来自FOTO_CODES表和FOTO数据(Image)的主表记录ID和ID。
Create another child table that will have the master table record id and ID from FOTO_CODES table and FOTO data (Image).
标准化。
