Error

[MuskanNazim]

See..I used your code for expense tracker from github...I have followed your YouTube video as well...but when I run the project everything is running...but not showing the values...means if I create the budget it's not showing..if I create a income source it's also not showing..don't know why..also on the dashboard page the tables containing values are empty..showing errors in app/dashboard/page.jsx and and in budgetlist.jsx,incomelist.jsx as well. Please help me

Potential solution

The primary issue reported is that the dashboard and lists for budgets and incomes are not displaying any values. This is likely due to the dependency on the user object and its properties, which are not being correctly populated or accessed. Additionally, there is a lack of error handling and loading states, which can lead to silent failures and poor user experience.

To solve this, we need to ensure that the user object is correctly populated before making any database queries. We should also add error handling to log any issues and provide feedback to the user. Finally, we should introduce loading states to differentiate between loading data and having no data.

What is causing this bug?

The bug is caused by the following issues:

1. User Dependency: The data fetching functions depend on the user object. If the user object is not correctly populated, the functions will not fetch data.
2. Email Address Access: The code uses user?.primaryEmailAddress?.emailAddress to filter data. If this property is not correctly populated, the queries will not return any results.
3. Error Handling: There is minimal error handling in the data fetching functions, which could lead to silent failures.
4. Loading State: The components do not explicitly handle loading states, leading to confusion between loading data and having no data.

## Analysis Report for `BudgetList.jsx` ### Overview The `BudgetList.jsx` component is responsible for fetching and displaying a list of budgets. It uses React hooks for state management and side effects, and it interacts with a database using the `drizzle-orm` library. The component also includes a `CreateBudget` component to add new budgets and refresh the list. ### Key Functionalities 1. **State Management**: - `budgetList`: Stores the list of budgets fetched from the database. 2. **User Context**: - `useUser`: Retrieves the current user information. 3. **Data Fetching**: - `getBudgetList`: An asynchronous function that fetches budget data from the database, including total spend and total items for each budget. 4. **Rendering**: - Conditionally renders either the list of budgets or placeholder elements if the list is empty. ### Potential Issues 1. **User Dependency**: - The `useEffect` hook depends on the `user` object. If `user` is not available or takes time to load, `getBudgetList` will not be called, resulting in an empty `budgetList`. 2. **Database Query**: - The query in `getBudgetList` uses `user?.primaryEmailAddress?.emailAddress` to filter budgets. If `user.primaryEmailAddress` or `user.primaryEmailAddress.emailAddress` is `undefined`, the query will fail or return no results. 3. **Error Handling**: - There is no error handling in the `getBudgetList` function. If the database query fails, the user will not be informed, and `budgetList` will remain empty. 4. **Loading State**: - The component does not explicitly handle loading states. While it shows placeholder elements when `budgetList` is empty, it does not differentiate between an empty state and a loading state. ### Recommendations 1. **Ensure User Data Availability**: - Add a check to ensure `user` and `user.primaryEmailAddress.emailAddress` are available before calling `getBudgetList`. 2. **Error Handling**: - Implement error handling in the `getBudgetList` function to catch and log errors, and possibly inform the user. 3. **Loading State**: - Introduce a loading state to differentiate between loading data and having no data. ### Suggested Code Changes ```javascript "use client" import React, { useEffect, useState } from 'react' import CreateBudget from './CreateBudget' import { db } from '@/utils/dbConfig' import { desc, eq, getTableColumns, sql } from 'drizzle-orm' import { Budgets, Expenses } from '@/utils/schema' import { useUser } from '@clerk/nextjs' import BudgetItem from './BudgetItem' function BudgetList() { const [budgetList, setBudgetList] = useState([]); const [loading, setLoading] = useState(true); const { user } = useUser(); useEffect(() => { if (user && user.primaryEmailAddress?.emailAddress) { getBudgetList(); } }, [user]); /** * used to get budget List */ const getBudgetList = async () => { try { const result = await db.select({ ...getTableColumns(Budgets), totalSpend: sql `sum(${Expenses.amount})`.mapWith(Number), totalItem: sql `count(${Expenses.id})`.mapWith(Number) }).from(Budgets) .leftJoin(Expenses, eq(Budgets.id, Expenses.budgetId)) .where(eq(Budgets.createdBy, user.primaryEmailAddress.emailAddress)) .groupBy(Budgets.id) .orderBy(desc(Budgets.id)); setBudgetList(result); } catch (error) { console.error("Failed to fetch budget list:", error); } finally { setLoading(false); } } return (

getBudgetList()} /> {loading ? ( [1, 2, 3, 4, 5].map((item, index) => (

)) ) : ( budgetList.length > 0 ? budgetList.map((budget, index) => ( )) : (

No budgets found.

) )}

) } export default BudgetList ``` ### Conclusion The primary issues in `BudgetList.jsx` are related to the dependency on user data, lack of error handling, and absence of a clear loading state. Implementing the suggested changes should help in resolving the issues mentioned in the user's ticket.

Changes on app/(routes)/dashboard/page.jsx

# Bug Analysis Report for `app/(routes)/dashboard/page.jsx` ## Overview The file `app/(routes)/dashboard/page.jsx` is responsible for rendering the dashboard page of the expense tracker application. It fetches and displays data related to budgets, incomes, and expenses. The user reported that the dashboard is not showing values for budgets and incomes, and the tables are empty. ## Key Areas to Investigate 1. **Data Fetching Logic**: Ensure that the data fetching functions (`getBudgetList`, `getIncomeList`, `getAllExpenses`) are correctly retrieving data from the database. 2. **State Management**: Verify that the fetched data is correctly set in the component's state (`budgetList`, `incomeList`, `expensesList`). 3. **Rendering Logic**: Check if the data is correctly passed to the child components (`CardInfo`, `BarChartDashboard`, `ExpenseListTable`, `BudgetItem`) and rendered properly. ## Findings ### Data Fetching Logic 1. **`getBudgetList` Function**: - Fetches budgets and joins with expenses to calculate `totalSpend` and `totalItem`. - Filters budgets by the user's email address. - Calls `getAllExpenses` and `getIncomeList` after fetching budgets. 2. **`getIncomeList` Function**: - Fetches incomes and calculates `totalAmount`. - Groups by income ID. 3. **`getAllExpenses` Function**: - Fetches expenses and joins with budgets. - Filters expenses by the user's email address. ### Potential Issues 1. **User Dependency**: The data fetching functions depend on the `user` object. If the `user` object is not correctly populated, the functions will not fetch data. 2. **Email Address Access**: The code uses `user?.primaryEmailAddress?.emailAddress` to filter data. If this property is not correctly populated, the queries will not return any results. 3. **Error Handling**: There is minimal error handling in the data fetching functions, which could lead to silent failures. ### State Management - The state variables (`budgetList`, `incomeList`, `expensesList`) are correctly initialized and updated with the fetched data. ### Rendering Logic - The fetched data is passed to child components (`CardInfo`, `BarChartDashboard`, `ExpenseListTable`, `BudgetItem`) for rendering. - The `BudgetItem` component is conditionally rendered based on the length of `budgetList`. ## Recommendations 1. **Ensure User Object is Populated**: - Verify that the `user` object is correctly populated before calling the data fetching functions. - Add a check to ensure `user?.primaryEmailAddress?.emailAddress` is available. 2. **Improve Error Handling**: - Add error handling in the data fetching functions to log errors and provide feedback to the user. 3. **Debugging and Logging**: - Add console logs or debugging statements to verify the data being fetched and set in the state. 4. **Conditional Rendering**: - Ensure that the components handle empty states gracefully and provide meaningful messages if no data is available. ## Example Code Improvements ```jsx useEffect(() => { if (user && user.primaryEmailAddress?.emailAddress) { getBudgetList(); } else { console.error("User email address is not available"); } }, [user]); const getBudgetList = async () => { try { const result = await db .select({ ...getTableColumns(Budgets), totalSpend: sql`sum(${Expenses.amount})`.mapWith(Number), totalItem: sql`count(${Expenses.id})`.mapWith(Number), }) .from(Budgets) .leftJoin(Expenses, eq(Budgets.id, Expenses.budgetId)) .where(eq(Budgets.createdBy, user?.primaryEmailAddress?.emailAddress)) .groupBy(Budgets.id) .orderBy(desc(Budgets.id)); setBudgetList(result); getAllExpenses(); getIncomeList(); } catch (error) { console.error("Error fetching budget list:", error); } }; const getIncomeList = async () => { try { const result = await db .select({ ...getTableColumns(Incomes), totalAmount: sql`SUM(CAST(${Incomes.amount} AS NUMERIC))`.mapWith(Number), }) .from(Incomes) .groupBy(Incomes.id); setIncomeList(result); } catch (error) { console.error("Error fetching income list:", error); } }; const getAllExpenses = async () => { try { const result = await db .select({ id: Expenses.id, name: Expenses.name, amount: Expenses.amount, createdAt: Expenses.createdAt, }) .from(Budgets) .rightJoin(Expenses, eq(Budgets.id, Expenses.budgetId)) .where(eq(Budgets.createdBy, user?.primaryEmailAddress?.emailAddress)) .orderBy(desc(Expenses.id)); setExpensesList(result); } catch (error) { console.error("Error fetching expenses list:", error); } }; ``` ## Conclusion The primary issue seems to be related to the dependency on the `user` object and its properties. Ensuring that the `user` object is correctly populated and improving error handling should help resolve the issue. Further debugging and logging will help identify any other potential problems.

Changes on app/(routes)/dashboard/incomes/_components/IncomeList.jsx

# Bug Analysis Report for `IncomeList.jsx` ## Overview The `IncomeList.jsx` component is responsible for fetching and displaying a list of incomes. The user has reported that the income data is not being displayed correctly, and the tables on the dashboard page are empty. ## Analysis ### Data Fetching Logic The data fetching logic is encapsulated in the `getIncomelist` function, which is called within a `useEffect` hook that depends on the `user` object. The function performs the following steps: 1. **Database Query**: It queries the database to fetch income data along with aggregated expense data. 2. **State Update**: It updates the `incomelist` state with the fetched data. ### Potential Issues 1. **User Dependency**: The `useEffect` hook depends on the `user` object. If the `user` object is not correctly populated, the `getIncomelist` function will not be called. 2. **Database Query**: The query uses `user?.primaryEmailAddress?.emailAddress` to filter results. If `user.primaryEmailAddress` or `user.primaryEmailAddress.emailAddress` is `undefined`, the query will not return any results. 3. **State Update**: If the query does not return any results, the `incomelist` state will remain empty, leading to no data being displayed. ### Rendering Logic The component renders a list of `IncomeItem` components if `incomelist` has data. If `incomelist` is empty, it renders placeholder divs with a loading animation. ## Recommendations 1. **Ensure User Data**: Verify that the `user` object is correctly populated and contains the necessary email address. 2. **Error Handling**: Add error handling to the `getIncomelist` function to log any issues with the database query. 3. **Loading State**: Consider adding a loading state to indicate that data is being fetched. ## Suggested Code Changes ### 1. Add Error Handling ```javascript const getIncomelist = async () => { try { const result = await db .select({ ...getTableColumns(Incomes), totalSpend: sql`sum(${Expenses.amount})`.mapWith(Number), totalItem: sql`count(${Expenses.id})`.mapWith(Number), }) .from(Incomes) .leftJoin(Expenses, eq(Incomes.id, Expenses.budgetId)) .where(eq(Incomes.createdBy, user?.primaryEmailAddress?.emailAddress)) .groupBy(Incomes.id) .orderBy(desc(Incomes.id)); setIncomelist(result); } catch (error) { console.error("Error fetching income list:", error); } }; ``` ### 2. Add Loading State ```javascript function IncomeList() { const [incomelist, setIncomelist] = useState([]); const [loading, setLoading] = useState(true); const { user } = useUser(); useEffect(() => { if (user) { getIncomelist(); } }, [user]); const getIncomelist = async () => { try { const result = await db .select({ ...getTableColumns(Incomes), totalSpend: sql`sum(${Expenses.amount})`.mapWith(Number), totalItem: sql`count(${Expenses.id})`.mapWith(Number), }) .from(Incomes) .leftJoin(Expenses, eq(Incomes.id, Expenses.budgetId)) .where(eq(Incomes.createdBy, user?.primaryEmailAddress?.emailAddress)) .groupBy(Incomes.id) .orderBy(desc(Incomes.id)); setIncomelist(result); } catch (error) { console.error("Error fetching income list:", error); } finally { setLoading(false); } }; return (

getIncomelist()} /> {loading ? ( [1, 2, 3, 4, 5].map((item, index) => (

)) ) : incomelist.length > 0 ? ( incomelist.map((budget, index) => ( )) ) : (

No incomes found.

)}

); } ``` ## Conclusion The primary issue seems to be related to the dependency on the `user` object and the database query filtering. By adding error handling and a loading state, we can better diagnose and address the issue. Ensure that the `user` object is correctly populated before making the database query.
