I know I can easily extract data from html input tag using request.form['email'] after POST method.
Is there a way to populate this particular input tag with something like:
request.form['email'] = current_user.email
which obviously throws 'ImmutableMultiDict' objects are immutable? (Without using FlaskWTF).
Any help would be much appreciated!
You can overwrite request.form :
from werkzeug.datastructures import ImmutableMultiDict
from flask import Flask,request
app = Flask(__name__)
@app.route('/')
def hello_world():
# overwrite request.form to add 'email'
tempo_form_dict = request.form.to_dict()
tempo_form_dict['email'] = 'Hello@World'
request.form = ImmutableMultiDict(tempo_form_dict)
## Then you can use request.form as it was inputted...
return str(request.form)
if __name__ == '__main__':
app.run(debug=True,host=None,port=5000)

Actually, this could be easily done using value attribute, e.g.:
<input class="email" name="email" value="{{ current_user.email }}" required/>
