问题
I've been starting working with GraphQL server
and Apollo client
. The code is written in Reactjs
. Now I want to get data from GraphQL server using any queries, and show data to the table in the UI. I use npm react-table
for table.
The table could look like this:
I can easily get and show data if the query response has no array. For example, I have the query input string below:
{
account {
firstName
lastName
id
}
}
And query result with no array
{
"data": {
"account": {
"firstName": "Marlen",
"lastName": "Marquardt",
"id": 2
}
}
}
In ReactTable component, I just fetch the data using data.account.firstName
<ReactTable
data={[
{
firstName: data.account.firstName,
lastName: data.account.lastName,
id: data.account.id,
}
]}
columns={columns}
/>
However, if query result has array I don't know how to fetch the data. Please take a look the picture query result with array
So how can I show all 5 toy's title
to table ?
This is my old code:
import React from 'react';
import s from './Test.css';
import { ApolloClient } from 'apollo-client';
import { HttpLink } from 'apollo-link-http';
import { InMemoryCache } from 'apollo-cache-inmemory';
import fetch from 'node-fetch';
import { graphql } from 'react-apollo';
import gql from 'graphql-tag';
import ReactTable from 'react-table'
import 'react-table/react-table.css';
const localURL = 'http://localhost:3000/graphql';
const client = new ApolloClient({
link: new HttpLink({ uri: localURL, fetch }),
cache: new InMemoryCache()
});
const columns = [
{
Header: "ID",
accessor: "id"
},
{
Header: "First Name",
accessor: "firstName"
},
{
Header: "Last Name",
accessor: "lastName"
}
]
class Table extends React.Component {
render() {
let { data } = this.props;
return (
<div>
<h2> ADMIN </h2>
<ReactTable
data={[
{
firstName: data.account.firstName,
lastName: data.account.lastName,
id: data.account.id,
}
]}
columns={columns}
defaultPageSize={10}
/>
</div>
);
}
}
const queryAccountList = gql`
query {
account{
firstName
lastName
id
}
}
}
`
const AccountListWithData = graphql(queryAccountList)(Table);
export default AccountListWithData;

As you can see, your ReactTable's data prop expects an array (or at least, in your example you're passing it an array of 1 object).
Note also that the data object returned by your GraphQL is of the form
{
account
{
firstName,
lastName,
id
}
}
So you could have defined your ReactTable data with data={[ data.account ]}
with the same result.
Now let's say you perform your Toys query, then the data returned will be of the form
{
allToy [
{
id,
title
},
{
id,
title
},
...
]
}
so if your definition of data remains the same (const { data } = this.props;
), then data.allToy
will be an array of { id, title }
objects.
So you can define your Toy ReactTable as:
<ReactTable
data={ data.allToy }
columns={columns}
defaultPageSize={10}
/>
