Dear Guru,
I have employed this code successfully within VS Code and verified its functionality. However, when deploying it to the Streamlit cloud web app, it appears that the application is not running as expected.
Please give me advices!
import streamlit as st
from docxtpl import DocxTemplate
import subprocess
import os
import time
from datetime import datetime
import io
#---------Function to render Word document-------------
def render_docx(data):
doc = DocxTemplate("template.docx")
doc.render(data)
return doc
#---------Function to print Word document----------------
def print_word_document(file_path):
word_exe_path = r"C:\Program Files\Microsoft Office\Office16\winword.exe"
process = subprocess.Popen([word_exe_path, file_path, "/mFilePrintDefault"])
#process.wait() # Wait for printing to finish
time.sleep(5) # Wait for 5 seconds
# Close the opened Word process after printing
subprocess.call(["taskkill", "/F", "/IM", "WINWORD.EXE"])
# Wait for the Word process to finish before deleting the file
while os.path.exists(file_path):
try:
os.remove(file_path)
break
except PermissionError:
time.sleep(0.5)
def main():
st.title("Create and Print Word File")
#----Create input section-------------------
name = st.text_input("Enter your name:")
#----Get current timestamp for the file name------
current_time = datetime.now().strftime("%Y%m%d%H%M%S")
#----If filename doesn't exist in session state, create a new one
if not hasattr(st.session_state, "filename"):
st.session_state.filename = f'{current_time}_{name}.docx'
#----Button to create and download Word file -----------------
if st.button("Create and Download Word File"):
doc = render_docx({'name': name, 'timestamp': current_time})
bio = io.BytesIO()
doc.save(bio)
st.download_button(
label="Download Word File",
data=bio.getvalue(),
file_name=st.session_state.filename,
mime='docx'
)
st.success(f"Successfully created and downloaded the Word file '{st.session_state.filename}'!")
#----Button to print the created Word file--------------------------
if st.button("Print Created Word File"):
if hasattr(st.session_state, "filename"):
#----Get information about the created file---------------------
output_filename = st.session_state.filename
st.write(output_filename)
output_path = os.path.join(r'C:\Users\phong.lh\Downloads', output_filename)
st.write(output_path)
print_word_document(output_path)
st.success(f"Printed the Word file '{os.path.basename(output_path)}' and successfully closed the file!")
if __name__ == "__main__":
main()
