Potential solution

The plan to solve the bug involves addressing issues in multiple files that interact to display the expenses. The main areas of focus are:

1. Database Connection and Schema: Ensure the database connection is secure and reliable, and the schema is correctly defined.
2. Data Fetching and Error Handling: Improve data fetching logic and add error handling in the page.jsx file.
3. Component Rendering: Ensure the ExpenseListTable.jsx component correctly receives and renders the expenses list, with proper error handling and loading states.

What is causing this bug?

The bug is likely caused by a combination of issues:

1. Database Connection Issues: The hardcoded database URL and lack of error handling in dbConfig.jsx could lead to connection failures.
2. Data Fetching Failures: The getBudgetInfo and getExpensesList functions in page.jsx lack error handling, which means any failure in fetching data will result in empty state variables.
3. Component Rendering Issues: The ExpenseListTable.jsx component may not be receiving the expensesList prop correctly or handling it properly, leading to no expenses being displayed.

Code

1. Database Connection (utils/dbConfig.jsx)

Changes:

• Move the database connection string to environment variables.
• Add error handling for the database connection.

import { neon } from "@neondatabase/serverless";
import { drizzle } from "drizzle-orm/neon-http";
import * as schema from "./schema";

const sql = neon(process.env.DATABASE_URL);

try {
  export const db = drizzle(sql, { schema });
} catch (error) {
  console.error("Failed to connect to the database:", error);
}

2. Schema Definition (utils/schema.jsx)

Changes:

• Verify the data type of the createdAt field and ensure data integrity.

export const Expenses = pgTable("expenses", {
  id: serial("id").primaryKey(),
  name: varchar("name").notNull(),
  amount: numeric("amount").notNull().default(0),
  budgetId: integer("budgetId").references(() => Budgets.id),
  createdAt: timestamp("createdAt").notNull(), // Changed to timestamp
});

3. Data Fetching and Error Handling (app/(routes)/dashboard/expenses/[id]/page.jsx)

Changes:

• Add error handling and loading states.

useEffect(() => {
  if (user) {
    getBudgetInfo().catch(error => {
      console.error("Failed to fetch budget info:", error);
      // Optionally set an error state here
    });
  }
}, [user]);

const getBudgetInfo = 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))
      .where(eq(Budgets.id, params.id))
      .groupBy(Budgets.id);

    setbudgetInfo(result[0]);
    await getExpensesList();
  } catch (error) {
    console.error("Error fetching budget info:", error);
    // Optionally set an error state here
  }
};

const getExpensesList = async () => {
  try {
    const result = await db
      .select()
      .from(Expenses)
      .where(eq(Expenses.budgetId, params.id))
      .orderBy(desc(Expenses.id));
    setExpensesList(result);
    console.log(result);
  } catch (error) {
    console.error("Error fetching expenses list:", error);
    // Optionally set an error state here
  }
};

4. Component Rendering (app/(routes)/dashboard/expenses/_components/ExpenseListTable.jsx)

Changes:

• Add prop type validation, conditional rendering, error handling, and loading states.

import PropTypes from 'prop-types';
import { useState } from 'react';

ExpenseListTable.propTypes = {
  expensesList: PropTypes.array.isRequired,
  refreshData: PropTypes.func.isRequired,
};

function ExpenseListTable({ expensesList, refreshData }) {
  const [loading, setLoading] = useState(false);

  const deleteExpense = async (expense) => {
    setLoading(true);
    try {
      const result = await db
        .delete(Expenses)
        .where(eq(Expenses.id, expense.id))
        .returning();

      if (result) {
        toast("Expense Deleted!");
        refreshData();
      }
    } catch (error) {
      toast.error("Failed to delete expense.");
    } finally {
      setLoading(false);
    }
  };

  return (
    <div className="mt-3">
      <h2 className="font-bold text-lg">Latest Expenses</h2>
      {loading ? (
        <p>Loading...</p>
      ) : (
        <div>
          {expensesList.length === 0 ? (
            <p>No expenses available.</p>
          ) : (
            <div>
              <div className="grid grid-cols-4 rounded-tl-xl rounded-tr-xl bg-slate-200 p-2 mt-3">
                <h2 className="font-bold">Name</h2>
                <h2 className="font-bold">Amount</h2>
                <h2 className="font-bold">Date</h2>
                <h2 className="font-bold">Action</h2>
              </div>
              {expensesList.map((expenses, index) => (
                <div key={index} className="grid grid-cols-4 bg-slate-50 rounded-bl-xl rounded-br-xl p-2">
                  <h2>{expenses.name}</h2>
                  <h2>{expenses.amount}</h2>
                  <h2>{expenses.createdAt}</h2>
                  <h2
                    onClick={() => deleteExpense(expenses)}
                    className="text-red-500 cursor-pointer"
                  >
                    Delete
                  </h2>
                </div>
              ))}
            </div>
          )}
        </div>
      )}
    </div>
  );
}

How to replicate the bug

1. Setup: Ensure the application is connected to the database using the hardcoded URL in dbConfig.jsx.
2. Navigate: Go to the expenses page for a specific budget.
3. Observe: Notice that no expenses are displayed, and there are no error messages or loading indicators.

By implementing the above changes, the application should handle database connections more securely, fetch data reliably with error handling, and render the expenses list correctly with proper user feedback.

Changes on utils/dbConfig.jsx

## Analysis Report ### File: `utils/dbConfig.jsx` #### Overview This file is responsible for setting up the database connection using the `neon` and `drizzle-orm` libraries. It imports the database schema from `schema.jsx` and establishes a connection to a PostgreSQL database hosted on Neon. #### Code Review ```javascript import { neon } from "@neondatabase/serverless"; import { drizzle } from "drizzle-orm/neon-http"; import * as schema from "./schema"; const sql = neon( "postgresql://finan-smart_owner:uk3aed9QZotj@ep-wispy-breeze-a5iadk8t.us-east-2.aws.neon.tech/finan-smart?sslmode=require" ); export const db = drizzle(sql, { schema }); ``` #### Potential Issues 1. **Hardcoded Database URL**: The database connection string is hardcoded, which is not a best practice. It should ideally be stored in environment variables for security reasons. 2. **No Error Handling**: There is no error handling mechanism in place to catch and log errors if the connection to the database fails. 3. **SSL Mode**: The connection string includes `sslmode=require`, which is good for security, but if there are SSL certificate issues, it could prevent the connection. #### Recommendations 1. **Environment Variables**: Move the database connection string to environment variables to enhance security and flexibility. ```javascript const sql = neon(process.env.DATABASE_URL); ``` Ensure that `DATABASE_URL` is set in the environment configuration. 2. **Error Handling**: Add error handling to catch and log any issues during the database connection setup. ```javascript try { const sql = neon(process.env.DATABASE_URL); export const db = drizzle(sql, { schema }); } catch (error) { console.error("Failed to connect to the database:", error); } ``` 3. **SSL Configuration**: Verify that the SSL configuration is correct and that the database server's SSL certificate is valid. #### Conclusion The database connection setup in `utils/dbConfig.jsx` appears to be straightforward but lacks error handling and uses hardcoded credentials. These issues could potentially lead to problems in establishing a connection to the database, which might be the cause of the expenses not showing up. Implementing the recommended changes should help in diagnosing and resolving any connection issues.

Changes on utils/schema.jsx

# Analysis Report for `utils/schema.jsx` ## Overview The file `utils/schema.jsx` defines the database schema using the `drizzle-orm` library. It includes three tables: `Budgets`, `Incomes`, and `Expenses`. The focus is on the `Expenses` table, as the issue reported is that nothing is showing on the expenses page. ## Schema Definition for `Expenses` The `Expenses` table is defined as follows: ```jsx export const Expenses = pgTable("expenses", { id: serial("id").primaryKey(), name: varchar("name").notNull(), amount: numeric("amount").notNull().default(0), budgetId: integer("budgetId").references(() => Budgets.id), createdAt: varchar("createdAt").notNull(), }); ``` ### Fields: - `id`: A serial primary key. - `name`: A non-nullable varchar field. - `amount`: A non-nullable numeric field with a default value of 0. - `budgetId`: An integer field that references the `id` field in the `Budgets` table. - `createdAt`: A non-nullable varchar field. ## Potential Issues 1. **Data Type Mismatch**: The `createdAt` field is defined as a `varchar`. If the application expects a date or timestamp, this could cause issues in data handling or display. 2. **Default Value for `amount`**: The `amount` field has a default value of 0. If the data being fetched does not explicitly set this field, it might lead to unexpected results. 3. **Foreign Key Constraint**: The `budgetId` field references the `id` field in the `Budgets` table. If there are any issues with the `Budgets` table or the foreign key relationship, it could affect the retrieval of expenses. ## Recommendations 1. **Verify Data Types**: Ensure that the `createdAt` field's data type aligns with how it is being used in the application. If it is meant to be a date or timestamp, consider changing its type accordingly. 2. **Check Data Integrity**: Ensure that all entries in the `Expenses` table have valid `budgetId` values that correspond to existing entries in the `Budgets` table. 3. **Review Default Values**: Confirm that the default value for the `amount` field does not cause any issues in the application logic. ## Conclusion The schema definition for the `Expenses` table appears to be generally correct, but there are a few areas that could potentially cause issues. Specifically, the data type of the `createdAt` field and the integrity of the foreign key relationship should be verified. Further investigation into how these fields are used in the application will help determine if they are the root cause of the issue.

Changes on app/(routes)/dashboard/expenses/[id]/page.jsx

## Analysis Report ### Overview The file `app/(routes)/dashboard/expenses/[id]/page.jsx` is responsible for rendering the expenses screen for a specific budget. It fetches budget information and expenses from the database and displays them using various components. ### Key Components and Functions 1. **State Variables**: - `budgetInfo`: Stores information about the budget. - `expensesList`: Stores the list of expenses related to the budget. 2. **useEffect Hook**: - Triggers `getBudgetInfo` function when the `user` object is available. 3. **getBudgetInfo Function**: - Fetches budget information and aggregates total spend and total items. - Calls `getExpensesList` to fetch the list of expenses. 4. **getExpensesList Function**: - Fetches the list of expenses for the given budget ID and orders them by descending ID. 5. **deleteBudget Function**: - Deletes all expenses related to the budget and then deletes the budget itself. ### Potential Issues 1. **Data Fetching**: - The `getBudgetInfo` function is responsible for fetching budget information and expenses. If this function fails or returns an empty result, the `budgetInfo` and `expensesList` will not be populated. - The `getExpensesList` function is called within `getBudgetInfo`. If `getBudgetInfo` fails, `getExpensesList` will not be executed. 2. **User Dependency**: - The `useEffect` hook depends on the `user` object. If the `user` object is not available or takes time to load, the data fetching functions will not be triggered. 3. **Error Handling**: - There is no error handling in the `getBudgetInfo` and `getExpensesList` functions. If the database queries fail, the user will not be informed, and the state variables will remain empty. 4. **Loading States**: - There are no loading states implemented. If the data fetching takes time, the user might see an empty screen without any indication of loading. ### Recommendations 1. **Add Error Handling**: - Implement error handling in the `getBudgetInfo` and `getExpensesList` functions to catch and handle any errors that occur during data fetching. 2. **Loading States**: - Add loading states to indicate to the user that data is being fetched. 3. **Check User Object**: - Ensure that the `user` object is available before attempting to fetch data. Consider adding a loading state or a retry mechanism if the `user` object is not immediately available. 4. **Debugging**: - Add console logs or other debugging mechanisms to verify that the database queries are being executed and returning the expected results. ### Example Code Adjustments ```jsx useEffect(() => { if (user) { getBudgetInfo().catch(error => { console.error("Failed to fetch budget info:", error); // Optionally set an error state here }); } }, [user]); const getBudgetInfo = 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)) .where(eq(Budgets.id, params.id)) .groupBy(Budgets.id); setbudgetInfo(result[0]); await getExpensesList(); } catch (error) { console.error("Error fetching budget info:", error); // Optionally set an error state here } }; const getExpensesList = async () => { try { const result = await db .select() .from(Expenses) .where(eq(Expenses.budgetId, params.id)) .orderBy(desc(Expenses.id)); setExpensesList(result); console.log(result); } catch (error) { console.error("Error fetching expenses list:", error); // Optionally set an error state here } }; ``` ### Conclusion The primary issue seems to be related to data fetching and the lack of error handling and loading states. Implementing the recommended changes should help in diagnosing and resolving the issue where expenses are not showing up.

Changes on app/(routes)/dashboard/expenses/_components/ExpenseListTable.jsx

# Analysis Report for `ExpenseListTable.jsx` ## Overview The `ExpenseListTable.jsx` component is responsible for rendering a list of expenses and providing functionality to delete an expense. The component receives `expensesList` and `refreshData` as props. ## Key Areas to Investigate 1. **Props Validation**: Ensure `expensesList` is being passed correctly and contains the expected data. 2. **Rendering Logic**: Verify that the component correctly renders the list of expenses. 3. **Error Handling**: Check if there is adequate error handling for data fetching and deletion. 4. **Loading States**: Ensure there are loading states to handle asynchronous operations. ## Detailed Analysis ### 1. Props Validation - The component expects `expensesList` to be an array of expense objects. If `expensesList` is not being passed correctly or is empty, the component will not render any expenses. - **Potential Issue**: If `expensesList` is `undefined` or an empty array, no expenses will be displayed. ### 2. Rendering Logic - The component maps over `expensesList` to render each expense. - **Potential Issue**: If `expensesList` is empty or not properly formatted, the map function will not render any items. ### 3. Error Handling - The `deleteExpense` function handles the deletion of an expense and uses a toast notification to inform the user. - **Potential Issue**: There is no error handling for the deletion process. If the deletion fails, the user will not be informed. ### 4. Loading States - The component does not handle loading states for data fetching or deletion. - **Potential Issue**: Users may not be aware of ongoing operations, leading to a poor user experience. ## Recommendations ### 1. Add Prop Type Validation Ensure that `expensesList` is passed correctly and is an array: ```javascript import PropTypes from 'prop-types'; ExpenseListTable.propTypes = { expensesList: PropTypes.array.isRequired, refreshData: PropTypes.func.isRequired, }; ``` ### 2. Add Conditional Rendering Add a check to render a message if `expensesList` is empty: ```javascript return (

Latest Expenses

{expensesList.length === 0 ? (

No expenses available.

) : (

Name

Amount

Date

Action

{expensesList.map((expenses, index) => (

{expenses.name}

{expenses.amount}

{expenses.createdAt}

deleteExpense(expenses)} className="text-red-500 cursor-pointer" > Delete

))}

)}

); ``` ### 3. Add Error Handling for Deletion Include error handling in the `deleteExpense` function: ```javascript const deleteExpense = async (expense) => { try { const result = await db .delete(Expenses) .where(eq(Expenses.id, expense.id)) .returning(); if (result) { toast("Expense Deleted!"); refreshData(); } } catch (error) { toast.error("Failed to delete expense."); } }; ``` ### 4. Add Loading States Implement loading states to inform users of ongoing operations: ```javascript import { useState } from 'react'; function ExpenseListTable({ expensesList, refreshData }) { const [loading, setLoading] = useState(false); const deleteExpense = async (expense) => { setLoading(true); try { const result = await db .delete(Expenses) .where(eq(Expenses.id, expense.id)) .returning(); if (result) { toast("Expense Deleted!"); refreshData(); } } catch (error) { toast.error("Failed to delete expense."); } finally { setLoading(false); } }; return (

Latest Expenses

{loading ? (

Loading...

) : (

Name

Amount

Date

Action

{expensesList.map((expenses, index) => (

{expenses.name}

{expenses.amount}

{expenses.createdAt}

deleteExpense(expenses)} className="text-red-500 cursor-pointer" > Delete

))}

)}

); } ``` ## Conclusion The primary issue seems to be related to the `expensesList` prop not being passed correctly or being empty. Implementing the above recommendations should help in identifying and resolving the issue. Additionally, adding error handling and loading states will improve the user experience.
