mysql - Foreign key is not assigned using sequelize in 1:1 association -

i have 3 models user, question , video

• a video belongs 1 user , 1 question
• user has many questions, while question has 1 video
• i have got association between user , video models done, video-question 1 not yet. foreign keys created on create method questionid not assigned.

hers snap shot of how models , create function looks like. video model

'use strict'; module.exports = (sequelize, datatypes) => {   var video = sequelize.define('video', {     transcription: {       type: datatypes.text     },   });    video.associate = (models) => {    video.belongsto (models.question,    {foreignkeycontraint : true , foreignkey: "questionid" });   }    video.associate = (models) => {     video.belongsto(models.user, {       ondelete: "cascade",       foreignkey: 'userid'     });   } return video;}; 

question model:

module.exports = (sequelize, datatypes) => {  var question = sequelize.define('question', {   text: {   type: datatypes.text,   allownull: false,   } }); question.associate = (models) => {  question.belongsto(models.script, {    ondelete: "cascade",    foreignkey: 'scriptid'  }); } question.associate = (models) => {  question.hasmany(models.questionvariation,  {   foreignkey: 'questionid',   as: 'questions',  }); 

}return question;};

for create function

create(req, res) {  return video   .create({     userid: req.body.user_id,     questionid: req.body.question_id,     transcription: req.body.transcription   })   .then(video =>      res.status(201).send(video))   .catch(error =>      res.status(400).send(error));  } 

the video created neglects existence of questionid.

okay have solved it, problem have add hasone association in question model
