flask/jinja2: form textinput set value

Question

How do I set the VALUE attribut of a text input field (HTML forms).

I tried it with:

Python:

@app.route("/function_a", methods=['GET', 'POST'])
def function_a():
    form = ReusableForm(request.form)
    query = "test value"
    if request.method == 'POST':
    name=request.form['name']
    return render_template('zeit.html', form=form, query_test=query)

HTML template:

{{ form.name(value="{{ query_test }}") }}

the website output is like:

<input id="name" name="name" required type="text" value="{{query_test}}">

expected website output:

<input id="name" name="name" required type="text" value="test value">

ReusableForm is a class so instead of setting the value in the template do it in python code. form.name="test value" — metmirr

In the template delete setting value, make sure you have only {{ form.name }} — metmirr

I got the solution:

in the HTML template I wrote only the variable without the brackets.

{{ form.name(value=query_test) }}

and the output is like I want it:

<input id="name" name="name" required type="text" value="test value">
