How to include more than one HTML-form in a FLASK view?
Question
I´m building a little web application using python 2.7 and flask (my first one).
I´m trying to include three HTML forms in one flask view to have all three of the forms on one webpage:
- One form to allow data upload (will be an XML-file)
- One Button to start a python process, that performs analysis on the XML-file
- One Button that allows download of the results of step 2
While I got it working, when using a separate view for each of the three steps, I somehow can´t get it done when trying to include all three steps in one view. Does anyone know what I am doing wrong?
Here´s my code so far. The HTML-code is included in the python script. Working with templates didn´t help me either. The HTML page is working, but the buttons don´t perform any action.
...
@app.route('/PAM', methods=['GET', 'POST'])
def start_PAM():
if request.method == 'POST':
if "Upload" in request.form.values():
file = request.files['file']
if file and allowed_file(file.filename):
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
print "File upload complete !!"
return redirect('/PAM')
elif "Start PAM" in request.form.values():
import os
os.system("D:\Python_Test\PAM\PAM_1st_Try.py")
print "PAM Process Finished!!"
return redirect('/PAM')
elif "Download" in request.form.values():
filename = "FILE.XML"
return redirect(url_for('download_file', filename=filename))
return '''
<!doctype html>
<title>Start PAM Process</title>
<h1>XML Upload</h1>
<form action="" method=post enctype=multipart/form-data>
<p><input type=file name=file>
<input type=submit value=Upload>
</form>
<p><h1>Start the PAM Process</h1>
<form name='Start PAM' method='POST'>
<p><input type="submit" value="PAM" class="submitButton"/>
</form>
<p><h1>Download Result</h1>
<form name='Download' method='POST'>
<p><input type="submit" value="Download" class="submitButton"/>
</form>
'''
@app.route("/downloads/<filename>")
def download_file(filename):
return send_from_directory(app.config['UPLOAD_FOLDER'], filename, as_attachment=True)
app.debug = True
if __name__ == '__main__':
app.run()

I think the step you're missing is to assign an action to the forms. At the moment the HTML doesn't know what to do with the form?
