json post issue

Ok, so here's the problem. I have a Notes form. It posts the information properly but lets say I'd like to post another post right after I hit submit note. It won't post it and it will fill the url eg: " [http://app.com/ticket/1?body=](http://app.com/ticket/1?body=)blahblah&?method=add ". If I want to post again I have to refresh the page, What am I doing wrong?

Here's my JS.

$('#noteform').submit(function(e) {
e.preventDefault();
var csrf_token = "{{ csrf_token() }}";
var ticketid = "{{ ticket.id }}";
var twoSecMin = $.Deferred();

$.ajax({
url: '/repair/addNote',
dataType: 'json',
type: 'post',
contentType: 'application/json',
data: JSON.stringify( {
"method": 'add',
"body": $('#body').val(),
"ticketid": ticketid,
"private_note": $('#private_note').prop('checked')
}),
processData: true,
success: function( data, textStatus, jQxhr ){
$('#notes').load(' #notes');
$('#notecount').load(' #notecount');
$('input[type=text], textarea').val('');
$('input[type=checkbox]').prop("checked", false);
},
error: function( jqXhr, textStatus, errorThrown ){
console.log( errorThrown );
alert('Error Posting Note!');
}
});


$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!/^(GET|HEAD|OPTIONS|TRACE)$/i.test(settings.type) && !this.crossDomain) {
xhr.setRequestHeader("X-CSRFToken", csrf_token);
}
}
});

});

and this is my controller logic.

@ticket.route('/addNote', methods=["POST"])
def addNote():
json = request.get_json()
method = json['method']

if method == 'add':
body = json['body']
private = json['private_note']
tid = json['ticketid']

# Create note!
newnote = Notes(
created_by = 0,
is_private = private,
ticket_id = tid,
body = body,
)

db.session.add(newnote)
db.session.commit()

elif method == 'delete':
noteid = json['noteid']

# Delete note.
notetodelete = Notes.query.filter_by(id=noteid).first_or_404()

db.session.delete(notetodelete)
db.session.commit()

elif method == 'update':
return None

return jsonify(result='done')

Upload Progress Bar

Hi everyone,

I was wondering if you could recommend a progress bar that will work with file uploads in Django. I see that there are several available, and I've tried several without any success. I was wondering if you could recommend one that you've been able to get working.

Thanks!

[Flask-SQLAlchemy] Querying association table in flask-sqlalchemy?

Let's say I have two models **Posts** and **Tags** and an association table **post_tags** that connects these models in a many-to-many relationship (one post can have one or many tags and each tag can have one or more posts attached to it):

post_tags = db.Table(
'post_tags',
db.Column('post_id', db.Integer, db.ForeignKey('posts.id'), primary_key=True),
db.Column('tag_id', db.Integer, db.ForeignKey('tags.id'), primary_key=True),
)

class Post(db.Model):
__tablename__ = 'posts'
id = db.Column(db.Integer, primary_key=True)
text = db.Column(db.Text, nullable=False)
created_at = db.Column(db.Integer, nullable=False)

class Tag(db.Model):
__tablename__ = 'tags'
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String, unique=True, nullable=False)


I want to obtain the most frequently mentioned tags from the **post_tags** table. SQLite query for this roughly looks like:

SELECT tag_id, count(tag_id) FROM post_tags GROUP BY tag_id ORDER BY count(tag_id) DESC;

How can I accomplish this in SQLAlchemy? I am using Flask-SQLAlchemy extension and SQLite as a DB driver.

Edit: formatting and grammar

[AF] Pagination not working, has_next and has_prev always gives None

Hi, so as the title suggests I have a problem regarding pagination. Here is the code I have tried to use (taken from [Miguel Grinberg's tutorial](https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-ix-pagination)).

def index():
"""View function for the index site, basically the main site.
Sorts posts by hotness"""
page = request.args.get('page', 1, type=int)
posts = Post.query.order_by(Post.hotness.desc()).paginate(
page, app.config['POSTS_PER_PAGE'], False)
next_url = url_for('index', page=posts.next_num) \
if posts.has_next else None
prev_url = url_for('index', page=posts.prev_num) \
if posts.has_prev else None
return render_template('index.html', title='Dopenet: You can do anything', posts=posts.items, next_url=next_url, prev_url=prev_url)

The index.html file is this:

{% extends "base.html" %}

{% block content %}
{% for post in posts if posts %}
{% include '_post.html' %}
{% endfor %}

{% if prev_url %}
<a href="{{ prev_url }}">Newer posts</a>
{% endif %}
{% if next_url %}
<a href="{{ next_url }}">Older posts</a>
{% endif %}

{% endblock %}

So I am guessing that both has_next and has_prev are giving `None` as a response, so hence no url for both prev and next.

What am I doing wrong and how can I fix this?

The rest of the code can be found here, if more context is needed:
