Usage

A usage example can be found at https://github.com/ricardo93borges/yamaform-example

Instantiate

var Yamaform = require('yamaform')
 
let databaseConfig = {
  host     : 'localhost',
  user     : 'username',
  password : 'password',
  database : 'database'
}
 
const yamaform = new Yamaform(databaseConfig, 'database.json')
 
//Generate tables using "database.json" file
yamaform.generateTables()

JSON file example:

{
    "person": {
        "name": "varchar(45)",
        "age": "integer",
        "hasMany": "dog",
        "hasOne":"address"
    },
    "dog": {
        "name": "varchar(45)",
        "age": "integer",
        "hasMany": "person"
    },
    "address": {
        "name": "varchar(45)"
    }
}

Relationships

You can specify many to one relationships with hasOne keyword and many to many relationships with keyword hasMany, on the example above, person has one address, so a foreign key called address_id will be created on person table.

Also a person has many dogs and a dog has many persons, so a associative table called person_dog will be created with the foreign keys person_id and dog_id.

If in json file the dog object didn't have a hasMany keyword, a foreign key called person_id would be created in dog table.

In many to many relationships both tables must have a name column.

Every table created will have a column called id that will be a primary key auto incremented

If a table has more then one many to one relationship use hasOne: [table1,table2]

Generate form

let props = {
  "method":'put',
  "id":1, //Used when method is put
  "action":'/',
  'formClass':'', //Optional

  'inputClass':'', //Optional
  'inputWrapperClass':'', //Optional 
  'buttonClass':'', //Optional
  'buttonText':'', //Optional
}
 
const getForm = async () => {

  console.log(form)
}

  'deleteUrl':'/your/url', // Optional, url to delete record, will become /your/url/(record id)
  'tableClass':'', // Optional
  'viewText':'', // Optional, text for link to view, default: view
  'deleteText':'' // Optional, text for link to delete, default: delete

   ],
   "otherTableName":[
      {"columnName":"value", "columnName":"value"},
      {"columnName":"value", "columnName":"value"}
   ]
}
 
const insert = async () => {
  let result = await yamaform.insert(data)
  console.log(result)
}
 
insert()

Update data in database

let data = {
   "tableName":[
      {"id":"value", "columnName":"value"},
      {"id":"value", "columnName":"value"}
   ],
   "otherTableName":[
      {"id":"value", "columnName":"value"},
      {"id":"value", "columnName":"value"}
   ]
}
 
const update = async () => {
  let result = await yamaform.update(data)
  console.log(result)
}
 
update()

update method expects a json object with table name and data (must contain the id of the record which will be update) to be inserted into database, returns an array of IDs of the affected rows
