Sails.JS + MySQL: Unknown column 'NaN' in 'where clause'

问题

this is my first time using sails.js with mySQL database and I'm really confused about this error.

I have a controller & model called 'company'. It relates to table 'company' in mySQL database. The table itself has one-to-many associations with two tables called 'module' and 'user' (each user/module must connect with one company id). I've set the foreign key in the MySQL database.

The problem is.. each time I open any page/action from this controller, there is this error:

    error: Sending 500 ("Server Error") response:

Details:  Error: ER_BAD_FIELD_ERROR: Unknown column 'NaN' in 'where clause'

This is my company model:

    module.exports = {
  attributes: {
      name:{
        type:"string",
        required:true,
        unique:true,
        minLength: 2
      },
      type:{
        type:"string",
        enum: ['hq','sub'],
        defaultsTo: 'hq'
      },     
      desc:{
        type:"text",
        required:true
      },
      logo: {
        type: 'string'
      },
      address: {
        type: 'text'
      },
      city: {
        type: 'string'
      },
      region: {
        type: 'string'
      },
      country: {
        type: 'string'
      },
      zipcode: {
        type: 'string'
      },
      phone_number: {
        type: 'string'
      },
      website: {
        type: 'string'
      }
  },
};

I have tried using 'autoPK: false', 'schema: true', add 'columnName/fieldName', but none of them is working.

What is the error means? How do I fix it?

Thank you very much.

回答1:

Oppening localhost:1337/company/index is your problem not any mysql or other orm problem!

This is a route config probem. When you open this URL the default sails behavior is that you try to access a specific company record through the default REST api. Check the default rest routes behavior.

To be more explicit in your case sails interpret that you are querying a specific company with the id "index" which is not a number NaN thus you get this error.

RESTful routes, where the path is always /:modelIdentity or /:modelIdentity/:id.
