// get all documents out of the database as an array and set it to local state
const tempArray: object[] = [];

getAllDocumentsAsArray(dbName).then((results: any) => {
  results.map((result: any) => {
    const dataItem = {
      date: result.date,
      Anxiety: result.anxiety,
      Depression: result.depression
    };
    tempArray.push(dataItem);
  });
  this.setState({ data: tempArray });
});

// getting all documents as object and saving the response in local state
getAllDocumentsAsObject("user")
  .then(response => {
    this.setState({ userDataObject: response });
  })
  .catch(error => {
    console.log(error);
  });

// save or update a new document to the database
saveScore = () => {
  const date = new Date();
  const idString =
    date.getFullYear() + "/" + date.getMonth() + "/" + date.getDate();
  const dateString =
    date.getMonth() + 1 + "/" + date.getDate() + "/" + date.getFullYear();
  const currentDocument = { _id: idString, date: dateString };

  upsertDocument(
    dbName,
    currentDocument,
    "anxiety",
    this.state.anxietySlider
  ).then(() => {
    upsertDocument(
      dbName,
      currentDocument,
      "depression",
      this.state.depressionSlider
    ).then(this.loadGraphDataFromPouchDB);
  });
