TemplateSyntaxError in Python Flask

[rgtr]

TL;DR

jinja2.exceptions.TemplateSyntaxError: invalid syntax for function call expression The line above is some of the code in profile.html This happens when I click on the profile link.

This is in python flask. I am getting an error
line 16, in template [CODE lang="html" title="html code"]<h2> <a href="{{ url_for('userinfo.profile', username=current_user.username, 'update_profile') }}"> update_profile_info </a> </h2> [/CODE]
jinja2.exceptions.TemplateSyntaxError: invalid syntax for function call expression The line above is some of the code in profile.html This happens when I click on the profile link. How do I fix this?

routes.py

profile route


[CODE title="python flask"]@userinfo.route('/profile/<string:username>', methods = ['GET'])
def profile(username):
user = User.query.filter_by(username=username).first_or_404()
# profilepicture = request.files['profilepicture']

posts = Posts.query.filter_by(id=current_user.id).first()
return render_template('profile.html', title='profile', username=user.username, post_id=posts.post_id)[/CODE]
update profile route

[CODE lang="python" title="flask python"]@login_required

@userinfo.route("/profile/<string:username>/update_profile", methods = ['POST','GET'] )

def update_profile(username):

form = UpdateAccountForm if form.validate_on_submit():

# do I need this line? Yes to make sure the username exists.

username = User.query.filter_by(username=username).first_or_404()

password = form.password.data

confirm_password = form.confirm_password

# should I get the hashed passwords before checking them?

if password != confirm_password:

# need better phrasing

flash("Your passwords fields don't match.")

else:



hashed_password = bcrypt.hashpw(password.encode('utf-8'), bcrypt.gensalt())

# user = User.query.filter_by(hashed_password='hashed_password').first()

user = User(hashed_password=hashed_password)

db.session.add(user)

db.session.commit()[/CODE]

We need to know the exact and entire error message and all the code that it references.

I will upload my github and the entire error message at a later time. Thanks

I found an error in the code. I had posts = User.query.filter_by... instead of posts = Posts.query.filter_by...

Here is the current error


Here is my github

https://github.com/NML240/flaskblog2/tree/masterIn app/userinfo/routes.py is the profile route.
The templates folder contain the html files.

You can't put a positional argument after a keyword argument in a Python function call. What are you trying to do with , 'update_profile'?

Usually this is true, however in this case the error was trivial and easy to spot.

I am trying to turn
@userinfo.route("/profile/<string:username>/update_profile", methods = ['POST','GET'] )
into a html link.

I assume @userinfo.route("/profile/<string:username>/update_profile", methods = ['POST','GET'] ) has to be @userinfo.route("/update_profile/<string:username>", methods = ['POST','GET'] ). I also noticed another error but I will fix that.

Not really.

# If you have a route:
@app.route('/profile/<string:username>/update_profile', methods=['POST', 'GET'])
def it_does_not_matter_what_you_call_it(username):
    # Do stuff with `username`.
# then you can create a url to that route with:
url_for('it_does_not_matter_what_you_call_it', username=current_user.username)

# If you have a route:
@app.route('/update_profile/<string:username>', methods=['POST', 'GET'])
def it_does_not_matter_what_you_call_it(username):
    # Do stuff with `username`.
# then you can create a url to that route with:
url_for('it_does_not_matter_what_you_call_it', username=current_user.username)
