How to post data to supabase through next.js - javascript

I currently have a simple next.js website where users can look at projects for an organization, and at the bottom of the page, the user can input a new project through the use of a form with multiple inputs. The database that i am currently using is Supabase.
My code currently takes in user input from each input box and stores them inside the newProject const, after which the data is then parsed into the createNewProject function and sent to Supabase.
const initialState = { solution_id: '', organization_id: '', budget_usd: '',other_info: '',country: '',project_duration_days: '',status: '',date_time_timezone: '' }
export default function Projects({ Projects }) {
useEffect(() => {
console.log(Projects)
}, [])
const [newProject, setProject] = useState(initialState)
console.log("User inputed data")
console.log(newProject)
const {solution_id, organization_id, budget_usd, other_info, country,project_duration_days,status,date_time_timezone} = newProject
const router = useRouter()
function onChange(e) {
setProject(() => ({ ...newProject, [e.target.name]: e.target.value }))
}
async function createNewProject() {
if (!solution_id || !organization_id || !country) return
const id = uuid()
newProject.id = id
const {data} = await supabase
.from('Projects')
.insert([
{ solution_id, organization_id, budget_usd,other_info,country,project_duration_days,status,date_time_timezone }
])
router.push(`/projects/${data.id}`)
}
return (
<div>
{Projects.map(project => {
return (
<div key={project.id}>
<h1><b>{project.Solutions.name} in {project.country}</b></h1>
<h2>Budget USD: {project.budget_usd}</h2>
<h2>Duration: {project.project_duration_days} days</h2>
<h2>Status: {project.status}</h2>
<h2>Organization: {project.Organizations.name}</h2>
<h2>Project Id: {project.id}</h2>
<button type="button" onClick={() => router.push(`/projects/${project.id}`)}>Donate now</button>
<br></br>
</div>
)
})}
<label htmlFor="solution_id ">solution_id</label>
<input onChange={onChange} value={newProject.solution_id} type="text" id="solution_id" name="solution_id" required />
<label htmlFor="organization_id ">organization_id</label>
<input onChange={onChange} value={newProject.organization_id} type="text" id="organization_id" name="organization_id" required />
<label htmlFor="budget_usd ">Last budget_usd</label>

<label htmlFor="project_duration_days ">Project Duration Days</label>
<input onChange={onChange} value={newProject.project_duration_days} type="text" id="project_duration_days" name="project_duration_days" required />
<label htmlFor="status ">status</label>
<input onChange={onChange} value={newProject.status} type="text" id="status" name="status" required />
<label htmlFor="date_time_timezone ">date_time_timezone</label>
<input onChange={onChange} value={newProject.date_time_timezone} type="text" id="date_time_timezone" name="date_time_timezone" required />
<button type="button" onClick={createNewProject} >Submit new project</button>
</div>
)
}
export async function getServerSideProps() {
const fetchOrgs = async () => {
let { data: Organizations, error } = await supabase
.from('Organizations')
.select('*')
return Organizations
}
const fetchSolutions = async () => {
let { data: Solutions, error } = await supabase
.from('Solutions')
.select('*')
return Solutions
}
const fetchProjects = async () => {
let { data: Projects, error } = await supabase
.from('Projects')
.select(`
id,
solution_id,
organization_id,
budget_usd,
country,
project_duration_days,
status,
Solutions(name),
Organizations(name)
`)
.order('id', { ascending: true })
console.log(Projects)
return Projects
}
const Organizations = await fetchOrgs();
const Solutions = await fetchSolutions();
const Projects = await fetchProjects();
return { props: { Solutions, Organizations, Projects } }
}
However, whenever I press the submit button, the console.log for the newProject, would show that there is not data being passed into the variables, only the empty placeholder data in the initialState const. As such, I am unsure about how to pass data from next.js input forms into a variable to be posted into supabase.

How to append multiple files to formData?

I have a form, and I have an input in the form, I upload several images in this input, like so:
<input type="file" name="gallery" onChange={imageHandler} required multiple />
And when I output the images in the console, it correctly displays an array of files, but when I append the images, formData.append("gallery", images); it is not saved as an array. It's saved as a File!
const [selectedFile, setSelectedFile] = useState();
const [images, setImages] = useState([]);
const token = localStorage.getItem("TOKEN");
const imageHandler = (e) => {
setImages([...images, e.target.files[0]]);
};
useEffect(() => {
images.length && console.log(images);
}, [images]);
console.log(images);
const sendDisease = async (e) => {
e.preventDefault();
console.log(images);
const form = document.getElementById("signUpForm");
const formData = new FormData(form);
formData.append("gallery", images);
console.log(formData);
try {
const api = "https://localhost/api/v1/website/disease/add";
const { data } = await axios.post(api, formData, {
headers: {
headers: { "Content-Type": "multipart/form-data" },
Authorization: `Bearer ${token}`,
},
});
toast.success(data.message, { autoClose: 15000 });
} catch (e) {
console.log(e);
toast.error(e.response.data.error, { autoClose: 15000 });
console.log(e.response.data.error);
}
};
const handleFileSelect = (event) => {
setSelectedFile(event.target.files[0]);
};
return (

Calling new FormData(form) is enough. You don't need to call formData.append("gallery", images) as the constructor will pick on its own all the images for you. So you may not even need this images state.
The code below would log all your files if you wanna be sure about it. I also created a working Codesandbox for testing.
export default function App() {
const handleSubmit = (e) => {
e.preventDefault();
const form = document.getElementById("signUpForm");
const formData = new FormData(form);
console.log(formData.getAll("gallery"));
};
return (
<form id="signUpForm" onSubmit={handleSubmit}>
<input type="file" name="gallery" required multiple />
<button>Sumbit</button>
</form>
);
}
If it's not working, try changing formData.append("gallery", images) to the code below (it's apparently what's needed for PHP servers for example):
images.forEach((image) => {
formData.append('gallery[]', image);
});
Here in my case Am using ASP.NET Core and its working fine
images.forEach((image) => {
formData.append('images', image);
});

Firebase stops saving when i use refresh

I want to refresh my page after save of newRider to Firebase. But when I use window.location.reload(); or with (false) it does not save. Without it it works.
And is it ok to have code that long in one file?
import React from "react";

const data = await getDocs(this.ridersCollRef);
return data.docs.map((doc) => ({ ...doc.data(), id: doc.id }));

}
The createRider() methods returns a Promise. You should wait for it to resolve and then proceed. Try refactoring the code as shown below:
const createRider = (event) => {
event.preventDefault();
return ridersDB.createRider({
firstName: newRider.firstName,
// ....
}).then(() => {
// resolved, proceed now
window.location.reload(false)
}).catch((e) => console.log(e));

File input always shows No file chosen

I'm building a form using React & Nodejs & MongoDB, where you can fill the form and upload a file with some other text inputs.
However, after i submit, i receive only text inputs in my database. The chosen file (desired to upload) doesn't appear at all in the database. I am expecting to get all the data form (the uploaded file and text inputed) in my database.
I tested my backend and it works correctly (it uploads all the inputs).
Ps: In browser, when i select a file (.pdf) to upload, the file input always shows no file chosen !

How do I add user inputs on click?

Self taught coder. Hopefully I can explain this adequately. Users create recipe cooking guides by inputing values like dish name, food category, cover img, etc. The steps array only has 1 step at the moment. I want a button that users can click that would add another "step" and "gif" to the steps array. Can anyone suggest a method to have another set of "step" and "img" render on screen when the user clicks the Add Step button? I have a handleAddSteps function with nothing inside. Somebody recommended using DOM? Just want to know if this is a good way to go before investing time down the wrong rabbit hole. Thank you kindly for any advice.

Please let me know if I'm missing any key information. Any advice is appreciated. Thank you.
Since each Guide can have multiple steps, I would rather create a state that handles an array of multiple step objects, than just a counter.
With this, you can render as much steps as you have in the array.
Then, adding steps just will be a matter of adding objects (with an empty state) to that array.
I made this functional example, that should be clear enough to show what I mean:
import React, { useState } from 'react';
const EMPTY_STEP = { text: '', file: null };
export default function App() {
const [guideSteps, setGuideSteps] = useState([{ ...EMPTY_STEP }]);
const handleStepChange = (stepIndex, property, value) => {
setGuideSteps((prevState) => {
const newGuideSteps = [...prevState];
newGuideSteps[stepIndex] = { ...newGuideSteps[stepIndex], [property]: value };
return newGuideSteps;
});
};
const handleAddStep = () => {
setGuideSteps((prevState) => [...prevState, { ...EMPTY_STEP }]);
};
return (
<div className="Steps">
{guideSteps.map((step, index) => {
return (
<div key={`step-${index + 1}`}>
<h2>{`Step ${index + 1}`}</h2>
<input type="text" value={step.text} onChange={(e) => handleStepChange(index, 'text', e.target.files ? e.target.files[0] : null, index)} />
<input type="file" value={step.file} onChange={(e) => handleStepChange(index, 'file', e.target.value, index)} />
</div>
);
})}
<button onClick={handleAddStep}>Add Step</button>
</div>
);
}

After Delete Mutation not Refetching Query (Apollo Graphql & Nextjs)

I recently switched my reactjs code to nextjs code, and I've observed that while I'm in reactjs code, When I delete data or perform a delete action, it appears like the queries are re-fetched and I am given the most recent or updated data in the datatable, but when I attempt it on Nextjs, it does not work. Is there a way to fix this?
Keep note I am using client side for this action.
Code
Form.js
export default function MainCategoryForm() {
const [name, setName] = useState("");
const [file, setFile] = useState();
const [status, setStatus] = useState("");

As shown above this code I have this refetchQueries: [{ query: FETCH_MAINCATEGORIES_QUERY }], in which after the add mutation or mutation it will refetch the query needed for the recent data to show in my datatable, I tried also putting that in the DeleteButton Component but it doesn't work.
Table
export default function MainCategoryTable({
mainCategory: { id, name, slug, status, url, createdAt },
}) {
return (
<>
<tr>
<td>{id}</td>
<td>
<img src={url} width={300} />
</td>
<td>{name}</td>
<td>{slug}</td>
<td>{status}</td>
<td>{dayjs(createdAt).format("h:mm:ss a")}</td>
<td>
<DeleteButton name={name} mainCategoryId={id} />
<Button>
<Link href={`/mainCategories/${id}`}>
<Icon name="edit" style={{ margin: 0 }} />
</Link>
</Button>
</td>
</tr>
</>
);
}
DeleteButton Component
export default function DeleteButton({ mainCategoryId, callback }) {
const [confirmOpen, setConfirmOpen] = useState(false);
const mutation = DELETE_MAINCATEGORY_MUTATION;
const [deleteMainCategoryOrMutation] = useMutation(mutation, {
update(proxy) {
setConfirmOpen(false);
if (mainCategoryId) {
const data = proxy.readQuery({
query: FETCH_MAINCATEGORIES_QUERY,
});
data.getMainCategories = data.getMainCategories.filter(
(ap) => ap.id !== mainCategoryId
);
toast.error(`Main Category Deleted`, { autoClose: 2000 });
proxy.writeQuery({ query: FETCH_MAINCATEGORIES_QUERY, data });
}
if (callback) callback();
},
variables: {
mainCategoryId,
},
});
return (
<>
<MyPopup content={"Delete Main Category"}>
<Button
as="div"
color="red"
floated="right"
onClick={() => setConfirmOpen(true)}
>
<Icon name="trash" style={{ margin: 0 }} />
</Button>
</MyPopup>
<Confirm
open={confirmOpen}
onCancel={() => setConfirmOpen(false)}
onConfirm={deleteMainCategoryOrMutation}
/>
</>
);
}
If you need any more code, such as my backend or any files to figure out what's wrong, I'll always amend my article. If you need any clarification or don't understand what I mean, please leave a comment down below.
You didn't set the refetchQueries in the DELETE_MAINCATEGORY_MUTATION mutation, instead you used the update option and read the query from the cache but you mutated the data, which is not the right way to do it, instead you should return a new array as follows:
const [deleteMainCategoryOrMutation] = useMutation(mutation, {
update(proxy) {
setConfirmOpen(false);
if (mainCategoryId) {
const previousData = proxy.readQuery({ query: FETCH_MAINCATEGORIES_QUERY });
const getMainCategories = previousData.getMainCategories.filter(
(ap) => ap.id !== mainCategoryId
);
const data = {
getMainCategories,
};
toast.error(`Main Category Deleted`, { autoClose: 2000 });
proxy.writeQuery({ query: FETCH_MAINCATEGORIES_QUERY, data });
}
if (callback) callback();
},
variables: {
mainCategoryId,
},
});
