# Display data in html format
This example shows you how to implement a smart field that displays HTML.
\
\
Here a **Movie** `hasOne` **movieCharacteristic**. \
\
On the `movies` collection, we want to implement a smart field (called `characteristics`) that will display all the characteristics of a movie.
## Requirements
* An admin backend running on forest-express-sequelize
## How it works
### Directory: /models
This directory contains the `movies.js` and `movie-characteristics.js` files where the models **movies** and **movieCharacteristics** are defined.
{% tabs %}
{% tab title="movies.js" %}
```javascript
module.exports = (sequelize, DataTypes) => {
const { Sequelize } = sequelize;
const Movies = sequelize.define('movies', {
title: {
type: DataTypes.STRING,
},
releaseYear: {
type: DataTypes.INTEGER,
},
rating: {
type: DataTypes.INTEGER,
},
picture: {
type: DataTypes.STRING,
},
academyAward: {
type: DataTypes.BOOLEAN,
},
}, {
tableName: 'movies',
underscored: true,
timestamps: false,
schema: process.env.DATABASE_SCHEMA,
});
Movies.associate = (models) => {
Movies.hasOne(models.movieCharacteristics, {
foreignKey: {
name: 'movieIdKey',
field: 'movie_id',
},
as: 'movieCharacteristic',
});
};
return Movies;
};
```
{% endtab %}
{% tab title="movie-characteristics.js" %}
```javascript
module.exports = (sequelize, DataTypes) => {
const { Sequelize } = sequelize;
const MovieCharacteristics = sequelize.define('movieCharacteristics', {
language: {
type: DataTypes.BOOLEAN,
},
graphicViolence: {
type: DataTypes.BOOLEAN,
},
nudity: {
type: DataTypes.BOOLEAN,
},
drugs: {
type: DataTypes.BOOLEAN,
},
gore: {
type: DataTypes.BOOLEAN,
},
}, {
tableName: 'movie_characteristics',
underscored: true,
timestamps: false,
schema: process.env.DATABASE_SCHEMA,
});
MovieCharacteristics.associate = (models) => {
MovieCharacteristics.belongsTo(models.movies, {
foreignKey: {
name: 'movieIdKey',
field: 'movie_id',
},
as: 'movie',
});
};
return MovieCharacteristics;
};
```
{% endtab %}
{% endtabs %}
### Directory: /forest
This directory contains the `movies.js` file where the smart field `characteristics` is implemented. The smart field returns an html-formatted list of the movie characteristics as a string.
{% code title="/forest/programs.js" %}
```javascript
const { collection } = require('forest-express-sequelize');
const sequelize = require('sequelize');
const models = require('../models');
collection('movies', {
fields: [
{
field: 'characteristics',
type: 'String',
get: (movie) => {
// check if the movie has a related characteristics record to return smtg or not
if (movie.movieCharacteristic) {
// list all your fields from the movieCharacteristics collection you want to display
const characteristicsNameList = ['language', 'gore', 'drugs', 'graphicViolence', 'nudity'];
// create empty string which will be filled with a div per field listed above - this string will be the value returned
let characteristicsList = '';
// add style that will be used to display the movie_characteristics info
const characteristicsDivStyle = 'margin: 24px 0px; color: #415574';
const characteristicsNameStyle = 'padding: 6px 16px; margin: 12px; background-color:#b5c8d05e; border-radius: 6px';
const characteristicsValueStyleRed = 'padding: 6px 12px; background-color:#ff7f7f87; border-radius: 6px';
const characteristicsValueStyleGreen = 'padding: 6px 12px; background-color:#7FFF7F; border-radius: 6px';
// iterate over the list of movie characteristics fields
for (index = 0; index < characteristicsNameList.length; index++) {
const fieldName = characteristicsNameList[index];
// check if the value of the field is 0 or 1 to add the relevant style (default is 0)
let characteristicsValueStyle = characteristicsValueStyleRed;
if (movie.movieCharacteristic[fieldName] === true) {
characteristicsValueStyle = characteristicsValueStyleGreen;
}
// insert the div with the field info to the string that will be returned
characteristicsList += `
${fieldName}
${movie.movieCharacteristic[fieldName]}
`;
}
return characteristicsList;
}
},
}
});
```
{% endcode %}
{% hint style="warning" %}
You will need to select the [rich text editor widget](https://docs.forestadmin.com/documentation/reference-guide/fields/customize-your-fields/edit-widgets#rich-text-editor) for this field in your collection settings to display the string returned by the smart field in html format.
{% endhint %}
