I'm trying to create a small inventory web app, and I'm using Python's micro framework Flask to do it. I need to create a form, so I'm using the wtforms module to help me generate it.
I wrote a basic class for my form in my __init__.py file, which you can see below:
from flask import Flask
from wtforms import Form, TextField, BooleanField, RadioField, IntegerField, TextAreaField, validators
app = Flask(__name__)
class InventoryForm(Form):
item = TextField('Item', [validators.Length(min=2)])
item_type = RadioField('Machine', 'Peripheral')
number = IntegerField()
notes = TextAreaField()
import inventoryapp.views
And in my views.py file, I have:
from inventoryapp import app
from flask import render_template
from wtforms import Form
@app.route('/', methods=['GET', 'POST'])
def index():
form = InventoryForm(request.form)
if request.method == 'POST' and form.validate():
entry = Item(form.item.data, form.item_type.data, form.number.data, form.notes.data)
db_session.add(entry)
flash('Item added.')
return redirect(url_for('index'))
return render_template('index.html', form=form)
Finally, I'm not sure if It's relevant but my index.html template looks like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>IT Inventory</title>
<link rel="stylesheet" type="text/css" href="../static/style.css" />
</head>
<body id="content">
<h1>IT-Ops Inventory App</h1>
{% macro render_field(field) %}
<dt>{{ field.label }}
<dd>{{ field(**kwargs)|safe }}
{% if field.errors %}
<ul class=errors>
{% for error in field.errors %}
<li>{{ error }}</li>
{%endfor %}
</ul>
{% endif %}
</dd>
{% endmacro %}
{% from "_formhelpers.html" import render_field %}
<form method="post" action="/index">
<dl>
{{ render_field(form.item) }}
{{ render_field(form.item_type) }}
{{ render_field(form.number) }}
{{ render_field(form.notes) }}
</dl>
<p><input type=submit value=Submit>
</form>
</body>
</html>
Now, every time I try to run my package it gives me:
NameError
NameError: global name 'InventoryForm' is not defined
Maybe I'm not importing some module that I need correctly in my views.py?
HELP! I've been trying to figure this out for days.
