Pattern: Malformed v-model directive

Issue: -

Description

This rule reports v-model directives in the following cases:

• The directive has that argument. E.g. <input v-model:aaa="foo">
• The directive has the modifiers which are not supported. E.g. <input v-model.bbb="foo">
• The directive does not have that attribute value. E.g. <input v-model>
• The directive does not have the attribute value which is valid as LHS. E.g. <input v-model="foo() + bar()">
• The directive is on unsupported elements. E.g. <div v-model="foo"></div>
• The directive is on <input> elements which their types are file. E.g. <input type="file" v-model="foo">
• The directive's reference is iteration variables. E.g. <div v-for="x in list"><input type="file" v-model="x"></div>

<template>
  <!-- ✓ GOOD -->
  <input v-model="foo">
  <input v-model.lazy="foo">
  <textarea v-model="foo"/>
  <MyComponent v-model="foo"/>
  <div v-for="todo in todos">
    <input v-model="todo.name">
  </div>

  <!-- ✗ BAD -->
  <input v-model>
  <input v-model:aaa="foo">
  <input v-model.bbb="foo">
  <input v-model="foo + bar">
  <div v-model="foo"/>
  <div v-for="todo in todos">
    <input v-model="todo">
  </div>
</template>
