Will the mega tutorial help me learn how to build more interactive apps than something like a blog?

I'm finished about a quarter of the mega tutorial and while it's very good, it also seems to be primarily focused on creating kind of a barebones blog style app without lots of user interactivity going on. My end goal is to make a speed reading app that can take text from an outside source (probably going to start with just taking wikipedia articles) and spacing the words into chunks of words you can read one at a time


ex: so instead of reading this word for word


[you would] [read it like] [this and] [read faster]

and maybe having every block highlighted with a different color.


 

Do you guys think the mega tutorial could help satisfy this?

Django Graphene tutorial question

I went through the graphene tutorial and using relays. But I have am a bit confused on one thing

If you go through the normal tutorial when you do single queries the query part is defined by


class Query(object):
category = graphene.Field(CategoryType,
id=graphene.Int(),
name=graphene.String())
If you do the one with relay the query part is defined as

class Query(object):
category = relay.Node.Field(CategoryNode)

If I want both features (single queries and filters from relays) does that mean I have to define a new variable for one to have both features? or do I just used relays and somehow the typings for the fields are inherited. I am just kind of confused by the ambiguous way the tutorials are written.

Masonite 2.0 Released - The Modern Python Web Framework!

I posted about the Masonite Python web framework a few months ago on this /r/python here and it received interesting feedback. During this time we received a few contributors who are just super awesome and contributed some awesome features.

We also were able to boost the speed of the framework to serve about twice as many requests in 30 seconds as Masonite 1.6 using some \`wrk\` benchmark testing.

Our contributors are extremely excited for this release and we can't wait to show it to the Python community. We think many of you will love the framework.

I currently have a python 3 program on my desktop. I run it with idle and everything is how I want it. What I want to do with Django is use this code to print its outputs on a webpage and have the user download it’s additional csv file output. I have managed to make a Django localhost and I am stuck at that point. I do not know how to use my python 3 code to run to webpage. The code is made up of api calls , I use postman to help me with sending the right parameters. I will add a example of code. All I want is for user to enter value such as “accountID” so that the api can complete the request and give them data for their own request. I would highly appreciate help on this

I have been trying for hours, from my understanding I have to make a view then send to HTML template

Good flask apps to study from?

I'm about a quarter of the way done with the mega tutorial and want to see if I know just enough to get my hands dirty. I want to build something more engaged than a blog site (in particular I'm trying to build a speed reading saccade app) and I'm looking for any potential fully developed flask apps on github and such that I could study from.

Database DML commands with Sqlite3 and Python 3

Question of how db.relationship() links databases together

Consider this bit of code from the mega tutorial:

class User(db.Model):
id = db.Column(db.Integer, primary_key = True)
username = db.Column(db.String(64), unique = True)
email = db.Column(db.String(120), unique=True)
password_hash = db.Column(db.String(128))
posts = db.relationship('Post', backref = 'author', lazy = 'dynamic')

def __repr__(self):
return '<User {}>'.format(self.username)

class Post(db.Model):
id = db.Column(db.Integer, primary_key = True)
body = db.Column(db.String(140))
timestap = db.Column(db.DateTime, index = True, default=datetime.utcnow)
user_id = db.Column(db.Integer, db.ForeignKey('user.id'))

def __repr__(self):
return '<Post {}>'.format(self.body)


 

The general goal here is for every post to be linked to an author, in a one to many relationship (as in a user object can have many posts).

But I'm not exactly sure what the implementation doing.

In

`posts = db.relationship('Post', backref = 'author', lazy = 'dynamic')`

is backref just an additional field that `posts` is feeding to a Post object, that happens to be the `ForeignKey` defined in the `user_id` field? I'm just confused how `posts` and `user_id` link together so that each user can have various blog posts linked to him.

thanks in advance!

How do I override the admin model delete action with confirmation beforehand?

I am trying to modify the bulk delete action that comes default with any registered model in the admin.

My goal is to override it and add in some extra functionality. This has actually been successful, but I lose the confirmation page beforehand. What happens instead is that the delete action fully executes and returns me back to the model's list view immediately. I want to keep the confirmation page as an intermediary *before* my action goes ahead and performs its customized deletion behavior on my selected objects.

Unfortunately, I've gotten a bit stuck on how to do this. Does anyone know how it can be done?

So far, my code is as follows:

class ImageAdmin( admin.ModelAdmin ):
form = ImageForm
actions = [ 'delete_selected' ]

def delete_selected( self, request, queryset ):
for obj in queryset:
obj.delete( )


admin.site.register( Image, ImageAdmin )

What can I do to make this work with the confirmation page?

Help in Python Simulation

Hello, i crunched numbers in calculating the position of the 3 body problem. I have 3.5 GB worth of data (x, y). But the problem is that i dont know how to use that data and plot it in such a way that it keeps updating in a reasonable amount of time (simulation visualization).

I just want a simple way to plot the 3 points and keeping it updating the positions while the program reads the file. Any help will be valuable.

how could i make this, im a little lost

okay so ive been playing with django for some time and i have reached a point where im stuck i have this problem

lets say i have products and marketplaces
so i can create a product for example a cup, with their base values like name stock etc (i can already do that good)

then i can create marketplaces lets say i have one in the us and other in germany for example where i want to sell my cups and each marketplace has its own things also like name etc.

then my problem comes when i want to be able to put each product on X number of marketplaces independently with its own new values so for example my cup may have a german name on the german marketplace and the price in € for example.
thats where i have a problem right now i have 3 tables like
product
marketplace
product_marketplace

but i dont know how to make a form where you select a product and a marketplace and save them, thats my main problem
also i want the default values on that form to be the ones of the product for example the default name etc

i hope i was clear enought and thanks in advance!

How to manage/organize data across multiple apps.

Hey guys,

New to Django but not new to OOP/Python. Reading through Two Scoops and they're talking about isolating apps to do one thing clearly. As they setup apps, they have model.py files for each app.

What I'm trying to understand is -- for my application -- a lot of data would be used/analyzed in numerous different apps. From the DB/Models perspective, what is the best way to organize this?

Django Datefield, TimeField, and DecimalField not displaying


Hi Djangonauts,
I am new to Django. Please forgive any silly mistakes in code or logic


My forms are not displaying the fields like they should(See Image).

The `price` field only lets me put numbers but there is no restriction on how many numbers It even lets me add a 15 digit number

The `date` and `time_from`, `time_to` fields just show long text-input fields. What am I doing wrong?


class LessonsForm(forms.ModelForm):
class Meta:
model = Lessons
fields = ('price', 'quantity', 'date', 'time_from', 'time_to')

def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['quantity'].label = "How many members in one class"
self.fields['price'].label = "How much do members have to pay to take lessons from you"
self.fields['date'].label = "When do you plan to offer lessons"
self.fields['time_from'].label = "What time do the lessons start"
self.fields['time_to'].label = "What time does the lessons end"

widgets = {
'price': forms.DecimalField(decimal_places=2, max_digits=5),
'quantity': forms.IntegerField(min_value=1, max_value=25),
'date': forms.DateField(format("%b %d %Y")),
'time_from': forms.TimeField(format('%H:%M')),
'time_to': forms.TimeField(format('%H:%M'))
}

**Below are the models**

class Lessons(models.Model):
user = models.ForeignKey(User)
post = models.ForeignKey(Post)
price = models.DecimalField(max_digits=5, decimal_places=2)
quantity = models.PositiveIntegerField()
date = models.DateField()
time_from = models.TimeField()
time_to = models.TimeField()


def get_absolute_url(self):
return reverse('posts:single', kwargs={'username': self.user.username,
'slug': self.post.slug})

**Below is the image of how the form now looks**

Is there an easy way/best practice for encrypting a field in a table?

I have a column of Tax Identification Numbers, kind of like SSN, but for businesses. It seems like a good idea to encrypt these.

I'll need to pull them back out, so hashing won't work.
