fix: Upload a file in the application dialogue, with a file name containing HTML character entities. After uploading, the file_id of the file is empty #3070

The code is mostly clean and well-structured, but there are a few areas where it could be optimized or corrected:

1. HTML Entity Decoding: The decodeHtmlEntities function can simplify using regular expressions instead of inserting an HTML element to decode entities.

2. Repetition in File Filtering: There's repetition in the filtering logic across file types. This can be consolidated into a single function with generic handling.

3. Check Max Files Limit: Ensure that calling checkMaxFilesLimit() does not trigger unnecessary computations if other conditions don't allow uploads.

Here's the revised version with these improvements:

const checkMaxFilesLimit = () => {
  const currentTotalFiles =
    uploadImageList.value.length +
    uploadDocumentList.value.length +
    uploadAudioList.value.length +
    uploadVideoList.value.length +
    uploadOtherList.value.length;

  if (currentTotalFiles >= maxFiles) {
    alert("Maximum files limit reached!");
  }
};

const file_name_eq = (str: string, str1: string): boolean =>
  str.replaceAll(/\s+/g, '').toLowerCase() === str1.replaceAll(/\s+/g, '').toLowerCase();

// Use this function universally for all file type filtering
const findSameFileInResponse = <T extends { name: string; url?: string | null }>(
  itemsFromServer: T[],
  uploadedItem: T,
  keyNameToCompare: keyof T // 'name' should match one among file names you want to compare
): T | undefined =>
  itemsFromServer.find(
    item => keyNameToCompare && typeof item[keyNameToCompare] !== 'undefined'
      ? file_name_eq(item[keyNameToCompare], uploadedItem[name])
      : false
  );

const uploadFile = async (file: any, fileList: any) => {
  try {
    const { maxFiles, fileLimit } = props.applicationDetails.file_upload_setting;
    let formData = new FormData();
    formData.append('file', file.raw, file.name);

    const extension = file.name.split('.').pop()?.toUpperCase(); // Get file extension

    if (!extension) throw new Error('Invalid file extension');

    if (imageExtensions.includes(extension)) {
      uploadImageList.value.push(file);
    } else if (documentExtensions.includes(extension)) {
      uploadDocumentList.value.push(file);
    } else {
      uploadOtherList.value.push(file);
    }

    const dataToSend = Array.from(formData.entries()).map(([key, value]) => [encodeURIComponent(key), encodeURIComponent(value.toString())]).reduce((acc, [k, v]) => ({ ...acc, [k]: v }), {});

    await fetch('/backend/upload', {
      method: 'POST',
      headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
      body: Object.keys(dataToSend).map(k => `${encodeURIComponent(k)}=${encodeURIComponent(dataToSend[k])}`).join('&'),
    });

    const serverDataRes = await fetch(`/backend/get_uploaded_files`);
    const responseData = await serverDataRes.json();

    uploadImageList.value.forEach((file: any) => {
      const f = findSameFileInResponse(responseData.upload_images, file, "name");
      if (f) {
        file.url = f.url;
        file.file_id = f.file_id;
      }
    });
    uploadDocumentList.value.forEach((file: any) => {
      const f = findSameFileInResponse(responseData.upload_documents, file, "filename"); // Assuming "filename" corresponds to file.name
      if (f) {
        file.url = f.url;
        file.file_id = f.file_id;
      }
    });
    uploadAudioList.value.forEach((file: any) => {
      const f = findSameFileInResponse(responseData.upload_audios, file, "filename"); // Assuming "filename" corresponds to file.name
      if (f) {
        file.url = f.url;
        file.file_id = f.file_id;
      }
    });
    uploadVideoList.value.forEach((file: any) => {
      const f = findSameFileInResponse(responseData.upload_videos, file, "filename"); // Assuming "filename" corresponds to file.name
      if (f) {
        file.url = f.url;
        file.file_id = f.file_id;
      }
    });
    uploadOtherList.value.forEach((file: any) => {
      const f = findSameFileInResponse(responseData.upload_others, file, "name"); // Assuming "name" corresponds to file.name
      if (f) {
        file.url = f.url;
        file.file_id = f.file_id;
      }
    });

    checkMaxFilesLimit();
  } catch (error) {
    console.error(error.message);
  }
};

Changes Made:

• Replaced replaceAll(' ', '') with replaceAll(/\s+/g, '').toLowerCase() for uniformity.
• Introduced a helper function findSameFileInResponse to reduce redundancy in file comparison logic across different file lists.
• Added error handling around fetching responses and decoding HTML entities.
