Form
The ROQ's generated B2B SaaS application provides basic forms for managing data within the application. It is easy to customize the form to meet your business needs.
How To Customize Form
Let's take an example of generated application called DigiShare, a digital book sharing web application.
The source code for the digital book sharing application, DigiShare, can be found here (opens in a new tab).
In the Book
section, we can create a new book with the Create Book
form. The form has the following fields:
- Title: The book title.
- Author: The book author's name.
- Select Organization: A dropdown to select the organization to which the book belongs.
- Select User: A dropdown to select user.

Create Field
The B2B SaaS generated application by ROQ is using Formik (opens in a new tab), an open source form library for React.
Supposed that we want to add another field for book description, let's called the field as description
:
- Description: it has
string
data type.
There are a few steps to add a field to the Create Book
form:
- Add the
description
property to theBookInterface
interface in theinterface/book
module. The updated code would look like this:
import { BookmarkInterface } from 'interfaces/bookmark';
import { HighlightInterface } from 'interfaces/highlight';
import { OrganizationInterface } from 'interfaces/organization';
import { UserInterface } from 'interfaces/user';
import { GetQueryInterface } from 'interfaces';
export interface BookInterface {
id?: string;
title: string;
author: string;
description?: string;
organization_id?: string;
user_id?: string;
created_at?: any;
updated_at?: any;
bookmark?: BookmarkInterface[];
highlight?: HighlightInterface[];
organization?: OrganizationInterface;
user?: UserInterface;
_count?: {
bookmark?: number;
highlight?: number;
};
}
export interface BookGetQueryInterface extends GetQueryInterface {
id?: string;
title?: string;
author?: string;
organization_id?: string;
user_id?: string;
}
- Update the
bookValidationSchema
in thevalidationSchema/books
module to include the validation rule for thedescription
field. The updated code would look like this:
import * as yup from 'yup';
export const bookValidationSchema = yup.object().shape({
title: yup.string().required(),
author: yup.string().required(),
organization_id: yup.string().nullable(),
user_id: yup.string().nullable(),
description: yup.string().required()
});
Here, the description
field is added with the yup.string().required()
validation rule, indicating that it is a required fields.
- Update the JSX code in the
BookCreatePage
component inpages\book\create
directory to include the newdescription
field. Add the following code inside the<form>
<FormControl id="description" mb="4" isInvalid={!!formik.errors?.description}>
<FormLabel>Description</FormLabel>
<Input type="text" name="description" value={formik.values?.description} onChange={formik.handleChange} />
{formik.errors.description && <FormErrorMessage>{formik.errors?.description}</FormErrorMessage>}
</FormControl>
This code creates a new FormControl
component for the description
field, similar to the existing form controls for title
and author
.
You cannot currently save book data with the new description
field. There are a few changes that need to be made to the database CRUD code in order to accommodate the new data. Please refer to this documentation for instructions on modifying the database schema.
Add description
Edit Field
Previously the description
field has added into the Create Book
form. To edit the saved data you need to add this field into our Editing Book
form too.
To do this you need to update the JSX code in the BookEditPage
component in pages\books\edit
directory. Add the following code inside the <form>
:
<FormControl id="description" mb="4" isInvalid={!!formik.errors?.description}>
<FormLabel>Description</FormLabel>
<Input type="text" name="description" value={formik.values?.description} onChange={formik.handleChange} />
{formik.errors.description && <FormErrorMessage>{formik.errors?.description}</FormErrorMessage>}
</FormControl>
This code addition is the same with FormControl
in Create Book
form.
Add description
Read Field
The book data is displaying in the Book list. To show book description
on the list, you need to change BookViewPage
component in pages\books\view
directory.
Update JSX in the BookViewPage
and add this code inside the <Stack>
component:
<Flex alignItems="center">
<Text fontSize="lg" fontWeight="bold" as="span">
Description
</Text>
<Text fontSize="md" as="span" ml={3}>
Add description field in the book data editor{data?.description}
</Text>
</Flex>
