Flask can't find applications file [duplicate] - flask

Refering to a directory in a Flask app doesn't work unless the path is absolute

Closed 4 years ago.
I have a standalone app that takes in an excel file and outputs a word doc. This works fine as standalone.
I have now tried to integrate it into a Flask application, but flask can't find the subfolder "templates" of my application. Here is my file structure:
my_flask_site
├── flask_app.py
├── __init__.py
├── templates
| ├── index.html
| └── report.html
├── uploads
| └── myfile.xlsx
|
└── apps
└── convert_app
├── __init__.py
├── main.py
├── report
| ├── __init__.py
| ├── data_ingest.py
| └── report_output.py
└── templates
└── output_template.docx
now I can't get the report_output.py file to find the output_template.docx file now it is in the flask application.
def run_report(file):
data = data_ingest.Incident(file)
priority_count = dict(data.df_length())
size = sum(priority_count.values())
print(priority_count)
print(size)
report = report_output.Report()
report.header()
report.priority_header(0)
i = 0
if '1' in priority_count:
for _ in range(priority_count['1']):
field = data.fields(i)
report.priority_body(field)
i += 1
report.break_page()
report.priority_header(1)
else:
report.none()
report.priority_header(1)
if '2' in priority_count:
for _ in range(priority_count['2']):
field = data.fields(i)
report.priority_body(field)
i += 1
report.break_page()
report.priority_header(2)
else:
report.none()
report.break_page()
report.priority_header(2)
if '3' in priority_count:
for _ in range(priority_count['3']):
field = data.fields(i)
report.priority_body(field)
i += 1
report.break_page()
if '4' in priority_count:
for _ in range(priority_count['4']):
field = data.fields(i)
i += 1
output = OUTPUT_FILE+f"/Platform Control OTT Daily Report {data.field[0]}.docx"
report.save(output)
print(f"Report saved to:\n\n\t {output}")
def main(file):
run_report(file)
if __name__ == "__main__":
main()
and here is the report_output.py (without the word format part):
from docx import Document
class Report(object):
def __init__(self):
self.doc = Document('./templates/pcc_template.docx')
self.p_title = ['Major Incident',
'Stability Incidents (HPI)',
'Other Incidents']
self.date = datetime.now().strftime('%d %B %Y')
def save(self, output):
self.doc.save(output)
There is more in the format_report.py file, but it is related to the function of the app. Where I am stuck is how I get the app to again see it's own template folder and the template file inside it.

I have solved my problem, after finding this post here Refering to a directory in a Flask app doesn't work unless the path is absolute.
What I take from this is that the file path has to be absolute from the Flask applications root folder, in this case "my_flask_site" is the root folder and adding the full file path solved the problem.
