I'm a total noob to flask. I'm just getting started with flask and jinja template engine. Please, kindly answer me. This is my html head tag,
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
{% if {{content}} %}
<title>WAJ - {{content}}</title>
{% else %}
<title>WAJ</title>
{% endif %}
</head>
The content variable is a string passed from flask, But I'm getting this error
File "d:\python programs\Flask Project\templates\user.html", line 6, in template
{% if {{content}} %}
jinja2.exceptions.TemplateSyntaxError: expected token ':', got '}'
I tried re-reading the code and checked for what could have gone wrong. But didn't find a solution. please help. 🙏
Well the issue in your code is simple. You don't need double curly braces {{ }} inside the {% if %} block.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
{% if content %}
<title>WAJ - {{ content }}</title>
{% else %}
<title>WAJ</title>
{% endif %}
</head>
Just replace the {{content}} with content and you are good to go. I would like to give you a nice little suggestion since you are a newbie, that is... Whenever you get a syntax error or something like that, you should look up to the documentation. It is a good habit that every programmer should adopt. Links to the documentations:
