Module "dracoengine" does not define a "draco" attribute/class

oh, right. Drat.
you can try from dracoengine import draco, or there's another solution but that one's much cleaner
native tide
works
native root
Yeah, in django all imports start at the "project level" -- or immediatley inside your outer autotek folder
native root
the reason import_string failed is it expects a __init__.py file I believe
native tide
should i maek a init.py
native root
I'd move the load_module to before all the views probably
native tide
ahh
native root
it indicates to python that the files in that directory should be considered available for import
native root
basically, from folder import file works but not import folder.file iirc
native tide
ah
what if draco engine is in /autotek/dracoengine/subdir/draco.py
would it be from dracoengine/subdir import draco
native root
from folder.folder import file

You can use appconfig.ready() to call something when django's about to be ready
See the green note as well, this should let you "start" a discord.py bot and run django at the same time, mostly

ive been trying to compress my requests body using zlib (post request)
What I did was:
garageString = zlib.compress(bytes(garageString, "utf8")) and I changed headers = {"Content-Type": "application/x-www-form-urlencoded"} into headers = {"content-encoding":"gzip"}.
For some reason my request still isnt working because it gives back the error "invalid request".
I strongly believe that this is because it recieves the request in the form of a b string with the b still in it 🤔
Any help would be appreciated, thanks!

@past cipher what's the db schema? that's a mysql error being bubbled up to sqlalchemy so it's likely a mismatch between the data model in python and the table schema in mysql
past cipher
InnoDB
I switched it to String for now, since it will work that way
I just weren't sure why float wasn't working
cold anchor
what does describe orders; return from the mysql shell in that db?
past cipher
native root
I suspect that Float(50) is the culprit
cold anchor
I'm not sure what the precision limit of the your mysql server is, but the docs here suggest it doesn't like values greater than 53 https://dev.mysql.com/doc/refman/5.7/en/floating-point-types.html
so your Float(100) might be what it's rejecting
try 53 instead

oh there's a float 100, missed that

Will test now
Yep that fixed it. I was getting confused. I had 100 on float as I was thinking of the max character count

What you're looking for @balmy olive is jinja templates
You write your template file like this:
cold anchor
might want to delete those pastes and make new ones that don't have the client_id in them
you should keep that private
native root
<html>
.....
{% for streamer in streamers %}
<div>{{ streamer.name }}</div>
{% endfor %}
Then you load it into your pythono and call template.render(streamers=streamers)
cold anchor
just follow this tutorial from their docs https://flask.palletsprojects.com/en/1.1.x/quickstart/#rendering-templates
native root
There's what I was looking for, thank you
balmy olive
Ah good point. Thanks, will try that
I'm a little confused. I have the jinja template setup but how do I actually pass the info from the different lists into it and get it to iterate through to generate the table?
cold anchor
return render_template('hello.html', mylist=mylist) will "render" the template and give it the variable "mylist", from here we can check the jinja documentation for looping
past cipher
{% for item in mylist %}
{{item}}
{% endfor %}

I might be going at this a bit backwards, sorry. I'm self taught. I need data from 3 different lists to create the table

balmy olive
If it helps I can try and explain what the goal of the code is and how it works in that script I sent
past cipher
This could be wrong since I have never used multiple for loops of list, but maybe:
{% for streamer in streamers %}
{% for name in names %}
{ % for link in links %}
{{streamer}}
{{name}}
{{link}}
{% endfor %}
{% endfor %}
{% endfor %}
do I stick that between the <td> tags in the jinja template?
If it's easier I could probably work with it just being the links there instead of everything
past cipher
<td>
{% for streamer in streamers %}
{% for name in names %}
{ % for link in links %}
<a href ={{link}}>{{name}} is live!</div>
{% endfor %}
{% endfor %}

I think anyway

a pseudo login? Or are you looking for like a production website?
balmy olive
ah it's not working because i've not added the code, but not sure where to stick it
for x in range(len(streamers)):
channel = client.streams.get_stream_by_user(streamers[x])
channel = str(channel)
if channel == 'None':
print('not live')
else:
webpage.write(" <tr>")
webpage.write(" <td>")
webpage.write(" <a href="+link[x]+">"+names[x]+ ' is live!'"</a>")
print(names[x])
webpage.write(" </td>")
webpage.write(" </tr>")
this is the code that I was using to ping the twitch.tv API to determine if a streamer from the list is live. it uses the channel = client.streams.get_stream_by_user(streamers[x]) to get that info then depending on what's returned it writes a line in the table or just prints something in the console
mint umbra
I apologize, I thought non-python was allowed in this channel and just saw some people talking. Won't ask any js stuff here again
balmy olive
It's obviously different now but I'm not sure what to stick in the part to ping the api to get the data for the table
acoustic oyster
If you use pure JS, you can just add, like, an input and check if that input is == user password.
Otherwise you need a DB and I would use something like php.
but yeah, you'll get more help on a non-python specific server

@balmy olive append it all to a list, and then render the list with the template

I'm actually here to ask a question too, lol.
I'm using Django and MySql. I am converting my JSON methods over to a MySql db.
I have a list of strings "inventory" and need to store this data in MySQL somehow. Any have any ideas as to what the best way to do this is?
My current plan is to save it as a string == "[item1, item2, item3]", but this seems sloppy
acoustic oyster
Can you elaborate? I am very new to this sort of stuff (as you may already know haha)
zealous siren
I don't know what invetory means
like inventory of what but if it's a user inventory, you have a table called inventory, it would have userid and inventoryid (or itemname)
acoustic oyster
it is a list of all the items a user has in my DD style game i.e inventory == ["sword", "potion"]
zealous siren
so inventory table with userid and itemname or itemid depending on how you structure it
items should be it's own table
acoustic oyster
basically all that needs to be stored is that string (the name of the item) for now.
it will belong to a class Character that will be many-to-one to a user
zealous siren
ok
acoustic oyster
what would be the best way to keep track of which items a Character has in its inventory?
acoustic oyster
ok. In this case each player will have several characters, each character having an inventory.
Would this be fine for performance then? if I have, say, 50 characters each with their own inventory?
acoustic oyster
ok, ty very much!
What do you mean by indexed? (I will be studying DBs today lol)
zealous siren
meaning the database server keeps internal check so it quickly answer select against that table without doing full table scan
acoustic oyster
ok, ty.
When this is done, I'll owe you a credit LOL
balmy olive
@past cipher I've added a loop that appends 0 to a list if a channel isn't live and 1 to the same list if the channel is live. Can I pass this to the jinja template then it will create a table row if the value is 1? And with flask, does it run the function to generate the page each time someone will load it?
past cipher
{% if variable == 1 %}
do something
{% endif %}
balmy olive
Hmm it's not creating the tables. Code looks like this
https://paste.pythondiscord.com/mivenajuzu.py - python
https://paste.pythondiscord.com/isebezoroc.py - template
It's not throwing an error. Just not creating the table
Or the rows for the table
dark hare
why are you doing
client = TwitchClient(client_id="CLIENTID") and passing CLIENTID as a string?
is that just your placeholder?
balmy olive
CLIENTID is the placeholder but I am passing it as a string
dark hare
have you read the docs?
balmy olive
for the twitchapi? No, but the issue is not with the api call I think. I've been passing the clientid as a string and it's been working properly
@past cipher That didn't work, still not generating the table
dark hare
why are you doing {% if live == 1 %}
live is a list of integers
not a single integer
you are appending strings
but then comparing a list of strings to a single integer
in the template
balmy olive
OY just said that, I changed it to {% if live == '1' %} and that still hasn't worked

you are making too big of a step
balmy olive
I've done that. I've got the whole thing working. I made this script yesterday and it generates a html file but because I want to host it as a web app I am now trying to migrate it to flask to make it all work
past cipher
Yeah my bad, its a list. So you should be checking if 0 or 1 is in the list.
{% if '1' in list %}

those for loops are not going to work how you expect
you should look up how for loops work

Using Django
User registers to site. However, if they go to create a post they are unable to it. It throws an Exception when the submit button advising that Author cannot be null ( it's linked by a foreign key).
Here is my models file:
User = get_user_model()
class Author(models.Model):
""" Inherits the auth user model """
user = models.OneToOneField(User, on_delete=models.CASCADE)
def __str__(self):
return self.user.username
class Category(models.Model):
""" Generic entries so posts can be filtered """
title = models.CharField(max_length=20)
def __str__(self):
return self.title
class PostView(models.Model):
"""Uses PostCreateView """
user = models.ForeignKey(User, on_delete=models.CASCADE)
post = models.ForeignKey('News_Post', on_delete=models.CASCADE)
def __str__(self):
return self.user.username
class News_Post(models.Model):
"""Inherits Category & Author Models """
title = models.CharField(max_length=100)
content = models.TextField()
date_posted = models.DateTimeField(default=timezone.now)
date_modified = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(Author, on_delete=models.CASCADE)
categories = models.ManyToManyField(Category)
featured = models.BooleanField()
post_img = models.ImageField(default='default.jpg')
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('post_detail', kwargs={
'pk': self.pk
})
def get_update_url(self):
return reverse('update_post', kwargs={
'pk': self.pk
})
def get_delete_url(self):
return reverse('delete_post', kwargs={
'pk': self.pk
})
def update_author(self):
np_auth = News_Post.author = Author.user
return np_auth
This is the Exception message:
IntegrityError at /create_post/
(1048, "Column 'author_id' cannot be null")
This is the stack trace also:
http://dpaste.com/2FC440W
The only hacky way around this would be creating an 'Author' via admin
acoustic oyster
The issue may be that you updated your model while it already existed in the database. So django is seeing that the Foreign key does not exist and cannot complete the table.
I literally just had a similar issue. I do not have any Users, but am trying to test my models, so I commented those lines out until I am ready to specify a User.
real hare
Did you resolve it?
acoustic oyster
Oh one sec, I just re-read your question
acoustic oyster
In this case, wouldnt your author BE the user?
this is how I have mine
Since your author essentially IS a user, I think this way makes more sense.
real hare
So drop the 'author' class then?
Or is there some way to instruct Django to populate this field?
acoustic oyster
I believe that is the best way.
The way I have it is: The User signed in at the time owns the post and is the author
The author class seems redundant to me, unless you plan on expanding on it.
real hare
I was thinking of maybe extending it to probably include like a 'profile' photo down the line
Or maybe I'll not bother
acoustic oyster
In that case, you would probably still want the User to be the foreign key, not an author
I have a separate profile for extra info, but the user "owns" the profile and also all the posts
real hare
Ah yes, I also do have a profile sort've model too
acoustic oyster
This is the result
real hare
so, I should just reuse the profile model?
acoustic oyster
The top left is just the username, but you can use djangos "jinja" to make it a full name or whatever.
real hare
or should I say, reference the profile model
User on my profile model is like:
user = models.OneToOneField(User, on_delete=models.CASCADE)
I think maybe just using the user from it then as the substance of post creation then 🙂
acoustic oyster
I use this for profiles, but this just allows the user to change their picture. The User
real hare
Oh that's cool I like that
I just referenced it in mine like {{user.get_full_name}}
Didn't use the str method
but that's a good way to also do it
acoustic oyster
You could probably force the Author to work in the foreign key, but I do not think it is worth it given what you are trying to accomplish
real hare
Yeah maybe not
acoustic oyster
also Corey Schafer on youtube is the hero of our generation.
real hare
I come from a Python 2 background, so this can be a bit perplexing at times too

@fickle fox yes user is undefind, it looks like you want to get a username from your form object, you should fo form.name or w/e you called your variable and pass that in instead of name=user. Furthermore even after you do that you would still have to finish your query. Fx user = Users.query.get(form.username) If the username from the form is your primary key for the users table. Or if it's not your PK you should do user = Users.query.filter_by(name=form.username).one_or_none() and then check if user is None

I like to learn mongoDB to make an API for my React project, should i start with Flask or Django ? Is another alternative for mongoDB ?
cold anchor
flask vs django is ultimately preference, django comes loaded with a bunch of things that you can add to flask manually or via community libraries
mongoDB's alternatives include any database (such as any flavor of SQL)
native tide
i have professional experience with .NET and pgSQL so i want to learn noSQL with python
so flask is smaller than Django and is better for start practicing ? If i gain experience with flask cna i learn DJango easily or the gap beetween the frameworks is too big ?

the fundamentals transfer pretty easily no matter what
and mongo is a great db to do nosql with, pymongo is the official library for that

hello guys anyone here used flask and jss to create an website application ?
i'm stuck at a problem
past cipher
__init__() takes from 1 to 2 positional arguments but 3 were given
check_token returns <Feedback 1> so its not False. However when using if (not form.validate_on_submit()) or (not check_token): this is where the error occurs
Actually its form.validate_on_submit() that is causing the issue
nvm I fixed it. My form had inputrequired() instead of input_required()

hey guys sorry to bother with my stupid as questions i am very new to web dev, when i import usercreationform then i create an instance of it what am i creating exactly? is it a dictionary with missing values
btw is acquiring a post request
im so confused, i mean my code is working and everything but im trying to understand whats truly happening under the hood
cold anchor
what's the code for usercreationform ?
timid sphinx
So currently I have a grid set up like an excel document. I have a title row on top with the data below. To create the sheet used:
grid-template-columns: 1.5fr 1fr 2fr 2fr 1.7fr 3fr 3fr 3fr 3fr 4fr .6fr 2fr 1fr 1fr 4fr;
I used this line both in my title class and my data class so they are the same size, then I populated the info.
I added resizability of the title with resize: horizontal. The issue I have now is i need the data class dimensions to mimic the title's dimensions so it resizes along side it
I don't want them to have the option to resize the tables from data, only title. I just need the data columns to be the same size of the title as the title expands/shrinks
cold anchor
I think that'll have to be done with javascript
timid sphinx
how so?
cold anchor
this looks helpful https://stackoverflow.com/questions/25679784/how-to-detect-resize-of-any-element-in-html5

anyone here who could help with django admin override?
i have created a new custom view for updating some fields of a model, it's kind of a change_view but there will be 3 or 4 of this views, with different subsets of model fields
the thing is that in add_view as in change_view, the datetime widget is admin styled, but when i create a custom view inside admin, the datetime field is nonadmin, (the difference is really anoying, admin style datetime has 2 separate inputs for date and time, the nonadmin has only one char input field with no browser widget for date or time)
thanks in advance

but found the error at my code
i'm stuck with a 2x4 table
it's oversized
to to make it fit?
how*
tried width
cold anchor
the container is fixed width, if you remove the width or max-width from the styles it should just fill to container the elements
wild thunder
the font is a little to big, i will certainly make it smaller,
the container is a bs4 card
cold anchor
do you have any customer styles on the embarques card container?
wild thunder
no, not really, just in the table itself
i tried to hardcode it directly in the table
but i have an custom.css file to add stuff if needed
cold anchor
as a sidenote: I don't think cards are semantically made to contain things like tables, so I understand this issue happening
what are the classes on the card container?
wild thunder
wow, actually that's a huge guess, i'll remove the card
hahaha
i was putting everything inside cards
but i guess it'll be better off the card
1 sec
it's definetely better, but still oversized
cold anchor
yeah if you're just trying to make a table with a container, title and border with a slightly different background color just do that

Hey, I have a question about flask. Previously have I used local static images and looped over into a render template and that works fine. But Now do I like to do the same but with a list of urls to img (ex imgur hosted) but I cant find any way to do that. Is that my google skills that failing me or is that not a proper usecase?
quick cargo
@soft trellis How are you getting the urls, Is it via context or just in the code or what?
soft trellis
@quick cargo right now do i have them in a json file that I loading
quick cargo
hmmm okay well you probably wanna pass it via context, as a dict or somthing
and just have src="{{ images.image1 }}" which would represent images['image1']
soft trellis
I will give that a try, thx 🙂

I'm using "djangorestframework-simplejwt==4.4.0" for the authentication. It uses a scheme which gives user two jwt, the access token and the refresh token. The access token is valid for small amount of time and must be provided for each authenticated call. The refresh token must be used to receive a new access token when the current one has expired. The access token is valid for 10 minutes, the refresh token for 1 day.
- 1 day seems short, I don't want my user to have to login every single day. I'd think that something like 30 days seem much more suitable. Is it a good idea ? My previous job would use 1h access token and 30 days refresh token.
- When should I refresh the access token ? When I get a 401 response ? When I notice it's expired as I'm checking it regularly ? I'm going to develop a front with Angular and I don't think it enforces anything on that aspect.

How can I get flask form data with javascript and put it inside of an “SRC=” attribute for iframe?
so, i want it like this..... User clicks on submit > get the form data > create "iframe" element > put the form data inside of "src" attribute
warm igloo
sounds .. dangerous?
you're saying you want someone to fill out a field and then on the next page, what they put in becomes part of the src attribute of the iframe? Taking that kind of data from the user and then turning around and embedding it in your site allowing them to call an iframe ... scary. Make sure you sanitize all those inputs.
distant trout
oh now that i think of it.. it actually does sound scary
ill think of something else then 😅
warm igloo
#1 rule of web dev -- don't trust ANYTHING from the user.
distant trout
oh lol.. Yeah, I'll keep that in mind from now on! thanks 😄
warm igloo
that's of course me saying all this not knowing your use case, I can imagine some legit reasons too
Let's say your user fills out a "name" field and you want load an iframe on the next page with src=mycoolanimationpage.com/?name={{form.name}} or something .. contrived example, but say the iframe just takes the name and animates it. And its via iframe cause the animation thingy is on another site. I guess? LOL. Just making this up.
So you CAN do this, just you would obviously want to sanitize the name, make sure they aren't passing anything nefarious, etc.
But ultimately I'd go "Hmm, do I really want to do it this way?"
or the form element is the location of a restaurant and you're dynamically passing the location to a google maps iframe, that's legit, still handle with care, but legit
etc
distant trout
yeah, i am going to try and keep it simple and try to see if there are other ways I can do this. sanitizing everything the user puts in seems hard lol

Hiya, did anyone have a problem where logging into Admin page (django) loads it without the CSS?
oblique tide
May someone please give me some advice? I’ve been trying to program in python I like it but I heard PHP is easier.
So should I switch to PHP?
dark hare
why? are u trying to get hired?
oblique tide
It’s not a necessity. I only just started learning python more seriously and consistently lately tbh.
Plus Google says that python is easier for novices anyways.
dark hare
I'm confused, what is your goal
oblique tide
I’d like to get into AI and data science but the light at the end of the tunnel feels too far away. I’d like to maybe get into algo trading one day but that maybe a crapshoot. On the positive side I could in theory be self taught. Unfortunately those are all advanced subjects.
Plus Idk if I’d like AI and data science.
For all Ik I could dislike it.
Those two fields would be very difficult for someone with no advanced maths background to break into.
Let alone someone with no industry experience.
It just doesn’t sound like a realistic goal for me to have anymore.
Unless I become like Elon Musk and study my bum off.
native tide
Is anyone working with Vue on front end ?
oblique tide
However in theory anyone could get started with AI.
“Ik that it works but not entirely how” mindset
dark hare
@oblique tide do you have a degree or education in that area?
oblique tide
Nope.
And that’s my point.
Plus Idek if I’d like to actually do it.
Sure the satisfaction is in achieving that big goal.
But I mean.
Can I and should I?
dark hare
hmm..I think getting a first job doing data science or AI related is unrealistic unless you have a project that clearty demostrates you have built something showing off those skills
oblique tide
That’s my point
Let alone without an advanced maths background.
Linear algebra, statistics, and calculus
dark hare
whats wrong with going into web dev first using python? then maybe look to it in the future?
oblique tide
Nothing. I was just wondering if PHP is easier?
dark hare
but i dont understand your goal? is it just to get hired?
oblique tide
No. To learn the basics and make stuff.
dark hare
python is known as one of the easier languages to learn for your first language
oblique tide
Oh ok. Then I’m on the right path.
Someone on YouTube suggested PHP.
So I suppose I was wondering if he was suggesting that it’s easier.
dark hare
thats all you need
I have a pinned post in the careers channel if u need more help
Good luck
dark hare
Then look for what companies are looking for in your area, what languages and skills and career progession
dont learn x y or z language because some guy on youtube said
learn what is realistic to you!
oblique tide
Yeah. I just wanna start small.
dark hare
Then you wont go far wrong with python!
oblique tide
Plus. Once I can get some stability in my life in the future and experience, getting into more advanced fields would be more of an achievable goal if I’m still interested.
dark hare
Exactly!
oblique tide
But that goal won’t likely be achieved until 10 years sadly 😂
I’ll likely live a fairly monastic life until then.
If I get married and have kids
I likely won’t ever achieve other things
Unless I’m a time management pro
There’s just so much to life.
oblique tide
That’s nice!
oblique tide
20
dark hare
if i could be 20 again, holy s***
the things i would of done differently
If you want a career in programming then get stuck in, you have more than enough time to do what u want to do! You will be years ahead of me thats for sure
dark hare
I have learned that nothing worth learning happens quickly, which is why good developers get paid so much money
oblique tide
Yeah. I heard they are even constantly learning new things.
dark hare
I dont want to try and persuade you, all I can say is python has changed my life in the last 2 years, and im almost 30. If you learn python well enough you will never regret it
oblique tide
Thanks! I’ll definitely take your advice seriously since you’re almost 10 years older than me lol.
dark hare
Because I was a laborer and delivery driver for years and years and I suffered from serious mental health problems for years because of it
and someone close to me send me a job advert for something called python I had never heard of
I had zero IT experience
read my post 😉
oblique tide
Your story sounds pretty inspiring ngl
dark hare
My advice would be, if you want a 9-5 job and have a stable income then programming is great, if you want to earn bigger bucks and overtake people that are years ahead of you then you have to dedicate more time to it
its a very competitive market
oblique tide
Yeah. I definitely wanna go big. But honestly a stable income and living is also a really nice goal to achieve. Unfortunately in this society, at least in the US, the social safety net isn’t as good as it could be.
dark hare
I live in UK, i plan to move to USA in next few years
oblique tide
Unless you’re a monk, you may not be happy with an unstable low income.
Or you’re rich to begin with
😂
Why would you move to the USA?
oblique tide
True. Plus you probably pay very high taxes.
dark hare
I pay 40% right now

Idk if that’s a lot. Sounds like it.

Hi, I'm wondering if it is possible to use the app.route decorator as a normal function.
Specifically, I want to know if something like this is valid
def setup(app):
app.route("/favicon.ico", lambda f: send_from_directory(os.path.join(app.root_path, "static"), "favicon.ico"))
instead of this
def setup(app):
@app.route("/favicon.ico")
def favicon():
return send_from_directory(os.path.join(app.root_path, "static"), "favicon.ico"))
The only reason for this is to silence the error about favicon not being used in my editor 🙂

nvm, app.add_url_rule seems to work well

pointA = models.ForeignKey(Point, on_delete=models.CASCADE, related_name='pointA', db_column='pointA')
pointB = models.ForeignKey(Point, on_delete=models.CASCADE, related_name='pointB', db_column='pointB')
I mean, if you try to add a pointC key in it and make a migration, it will ask you for the default
honest dock
No, since the table is empty..
jagged lark
Alternatively you can get rid of the whole migration file, but you'll have to create a new database
It doesn't matter
jagged lark
The migration history is like a git history, you need to be able to go back and forth, no matter what the database contain
Well, delete the migrations folder, make a new one, and delete and recreate the database on your dev server

Nice!

@vestal hound when i add another movie the items stay tho?
abstract python
I'm following the Django Girls tutorial, and have come unstuck with the post_detail section.
In my urls.py I've got got this:
path('', views.post_list, name='post_list'),
path('post/<int:pk>/', views.post_detail, name='post_detail'),
]
Which is exactly what it says to do in the tutorial. However whenever I click on a link, it tries to go to:
````http://127.0.0.1:8000/{% url 'post_detail' pk=post.pk $}```
and thus gives me an error.
but I'm not sure what I did wrong.
fading vortex
that tutorial just follows the django docs
fading vortex
is that urls pattern in your main app
i try to make another movie but the relationships with the actors carry onto it
from the first movie
vestal hound
those are all the objects of that type that exist
fading vortex
LOOL im sorry
abstract python
@gloomy acorn views.py has (the relevant bit at least), this:
post = get_object_or_404(Post, pk=pk)
return render(request, 'blog/post_detail.html', {"post": post})```
Which I've checked against the tutorial and that's what they've got as far as I can tell.the link is:
<h2><a href="{% url 'post_detail' pk=post.pk $}">{{ post.title }}</a></h2>
vestal hound
I'm like 95% sure
something is wrong with your template
I don't actually use Django templates, but it's not your urls.py that has an issue
abstract python
that wouldn't surprise me tbh, HTML is the thing I've learned least-recently so is probably the most likely thing for me to botch 😄
vestal hound
because basically
what is happening is
the link that is generated by your template is wrong
think of it this way
URLs are addresses, and views are the buildings that appear at each address
i.e. URLs answer "where is this thing" and views answer "what does this thing do"
what's happening above is that you are getting the wrong link
not that you have the correct link but it's doing the wrong thing
and the reason for that is that your template should be generating the right link, but it's not
abstract python
yeah, not sure where all the %7B% stuff is coming from. IIRC %20 is a space character?
vestal hound
if you look at the URL in your a, it looks like this: {% url 'post_detail' pk=post.pk $}
yes
it's basically a way to encode URIs (URLs are a type of URI)
gloomy acorn
@abstract python i ll give u my example
<a style="text-align:center;" href="{% url 'articles:detail' a.id %}"><h2 style="margin-top:30px;background:#79AEC8;">{{a.art_title}}</h2></a>
urlpatterns = [ path('', views.index, name = 'index'), path('<int:article_id>/', views.detail, name = 'detail'), ]
def detail(request, article_id): try: a = Article.objects.get(id=article_id) except: raise Http404('Page Not Found') return render(request, 'articles/detail.html', {'article' : a})
vestal hound
okay I think
I see the problem
you have an $ where you should have a %
right before the closing }
abstract python
wellll that's incredibly embarassing 😄
vestal hound
that's my guess, based on what the logical syntax would be
abstract python
yeah, that works fine now. Sorry for wasting your time.
probably should've noticed that myself heh.

i dont understand rn im sorry doing my own work
vestal hound
@abstract python no problem
if you were comparing it to something from a tutorial
one thing that can help is to copy-paste from the tutorial and ctrl-F in your code
gloomy acorn
ok then
abstract python
@vestal hound Aye, I was stubbornly refusing to copy and paste and work it out on my own, when in reality doing that after 10 minutes or so just to find any differences would've saved a lot of time!
vestal hound
no, no
you should work it out on your own
typing the code out yourself is good for your learning
but when comparing to a source ctrl-f is helpful
abstract python
yeah, that's what I mean. Writing the code myself = good. Refusing to copy and paste even to ctrl+f to see what's different in my code = bad.

I want my app to work on 80 port but I don't wanna run the entire program as root. Is there a way I can make 80 port nonpriveleged or something
zealous siren
no
but you can change permissions to allow certain binary ability to do it
cap_net_bind_service is what you are looking for
most people wouldn't recommend it
haughty root
But if I set it for python interpreter all programs willbe able to use a priveleged port
zealous siren
if you want to run something like Flask/Uvicorn or like, run Nginx in front then proxy incoming on port 80 to whatever high port you select
haughty root
ok gotta learn about nginx
zealous siren
or docker
basic nginx as proxy is really easy
I think config file will be like 7 lines

Yeah, recreating your prod environment is generally a good idea

Docker look into docker

Is webscraping against Reddit's TOS?
past cipher
Hey. So I'm working with flask, and I have a question. I have a javascript file called main.js which I use for every single page. I load by using include. Now I have /edit-product and it gets passed a list from the backend called product. If I include a script tag at bottom of my page, I can use the product variable like: alert('{{product.name}}'). However if I do the same in my main.js file, it doesn't work.
How do I pass variables through to the main JS file ?
@rigid mist use the reddit API
crisp saddle
@past cipher I would generally discourage of making frontends in flask that needs this, however it can be done:
You almost had it yourself,
In your main.js just make a setup function that you call from your HTML after you include main.js that takes the thing you want as a parameter.

How is python used in web dev? It is in the web page or it running on the server and does things on it or with the page?
zealous siren
I do REST APIs as well
people do make full web sites with Python using Flask/Django but that's not "new" hotness
crisp saddle
@zealous siren what framework do you like for REST API's?
native tide
I think Flask is pretty good for this. I‘ve seen some people using it for REST APIs
crisp saddle
That's what I use too, and have been for the past 2 years, but I think I'll try Fast API next time :-)
zealous siren
FastAPI
past cipher
@crisp saddle would you mind sharing why you would discourage it?
I managed to fix it by doing inline script styles
I thought I could of used {% with %} but turned out I couldn't
I really do need to learn Javascript soon though. I'm having nothing but problems..
zealous siren
It's just so easy to get going with FastAPI

{% for item in codes %}
<script>
document.getElementById('digital_codes').append('{{item.code}}');

This seems to only append the first item, but I'm not sure why
and I know its going to produce multiple script tags, but I have no idea how I would do a for loop inside a script tag while looping through a list
pulsar ivy
Get all elemenents by id

Like that you are selecting only first "thing" with that id

Hmm

it should append each item.code to the text area
but its only appending the first code
it creates the script tags though, just doesn't append:

distant trout
so I have been working on making a flask blog that is decent for a beginner I'd say(4 weeks). Now I am thinking of learning Django. Is that a good idea or should I keep learning more about Flask?
quasi ridge
hard to answer.
If your goal is to just learn for the sake of learning, then yes: they're both popular frameworks, and it'd be interesting and useful to know how they're similar, and how they're different
but if you just want to serve up some simple web pages, and flask is working, then ... maybe not
distant trout
hmm. I feel like I want to learn more about Django and maybe how flask/django are similar. I think im going to give it a shot
quick cargo
They are overall quite diffrent
One is a very Heavy framework which controls how you lay stuff out heavily (django)
The other is a micro framework where you have much better low level control but the framework does less for you (flask)
distant trout
Yeah, I feel like I kind of plateaued with my flask project, dont know what more to add or what more I CAN add. So maybe its time to check out django
onyx gulch
I'm using flask. How can I have bearer tokens work for only certain endpoints? So say I want token 1 to access /test, and not be able to access /hello, and token 2 to only access /hello, and not /test
crisp saddle
Are you using Flask Restplus @onyx gulch ?
Well the answer is kinda the same, you just make a decorator that requires it for an endpoint, and leave it out if the endpoint doesn't need token auth 🤷♂️
native tide
Error:
TypeError at /register/RegistrationForm() missing 1 required positional argument: 'UserCreationForm'
Code: https://hastebin.com/debanusiyo.py
Full Traceback: https://hastebin.com/tedawinido.sql
can somebody please help me?
crisp saddle
@native tide it's telling you, you are missing a required argument.
crisp saddle
I have no experience with that framework but the overall design pattern is the same I would assume.
onyx gulch
With rest plus can you specify which token is needed for the endpoint
crisp saddle
can you show me an endpoint that has auth?
onyx gulch
So I could have more than one token
alr
one moment
from flask import Flask, jsonify, request
from flask_httpauth import HTTPTokenAuth
app = Flask(__name__)
auth = HTTPTokenAuth(scheme = "Bearer")
tokens = ['abc']
@auth.verify_token
def verify_token(token):
if token in tokens:
return token
@app.route('/test', methods = ['GET'])
@auth.login_required
def test():
return jsonify(databasemanager.getAllProducts())
if __name__ == '__main__':
app.run(debug=True)
So the reason you wanna do this, is because you don't want to develop user roles?
crisp saddle
I see, well you could make a decorator that is decorated by @auth.login_required
and in that decorator decode the token and see if it's of the type that you need.
sec
actually what's wrong with your verify token @onyx gulch ?
onyx gulch
no i was just wondering if i could have different tokens access different enpoints
endpoints
crisp saddle
so verify_token is the decoded token? 'abc' ?
in that case you just create two type of tokens, user-role#somerandomstrings
and then check the role when you verify it?
onyx gulch
can i access which route is requested via verify token
lavish canopy
I haven't developed a site in flask yet, is it like WAY easier than Django?
Been working on this Django site for like 2 months (because I'm learning from scratch and want to make sure I understand everything) and I barely feel like I'm making headway
I broke the site once by referencing objects by IDs and then had to change them all to reference by PKs instead
I don't know why it worked... But it worked
Before I go further into things, do I HAVE to reference HTML files that are in apps instead of just a folder in the main directory?
I'm writing a blog and e-commerce app, but they all live in a single web app
Ideally I'd like for a user to simply make ONE account that can access the other apps in the project

Hey guys im trying to refresh a webpage from my flask app every five minutes but I cant figure out how. Basically it is webscraping and uploading it to the webpage for real time data. However I cant figure anything about refreshing. Anyone know how?

@signal pasture you can do it in pure html :-)
@signal pasture
<meta http-equiv="refresh" content="300; URL=http://www.yourdomain.com/yoursite.html">
if it's the same page you can omit URL

How do I import a html file in a html file, for example an navigation bar in my base file without it overwriting other things?
glass sandal
{% extends %}
limber laurel
If I do that with my nav bar to my base html file I only see the mav bar
glass sandal
{% extends filename %} to be specific
limber laurel
And nothing else
glass sandal
You have to put blocks
Like {% block navbar %}
{% block body %}
You define these in the navbar code
and write it in another page
Just learn a bit more Jinja2
limber laurel
Ok, ty
glass sandal
np
limber laurel
If I have fir example block content defined in a different file I ahould call it differently just like a variable right?

{% block blockname %}
And then like this :
{% extends "index.html" %}
{% block head %}
<title>Hello</title>
{% endblock head %}
Ty very much everything works now, had an error for a bit and I had forgotten to use "" when extending 😅

Guys why does Flask have less job opportunities than Django?
Just curious
Like flask could do anything that django does
It's more flexible
and ...
I'm fan of both btw
limber laurel
You need more different libraries than Django, for example an admin pannel, in flask you would need to make it bacically yourself, but Django already comes with things like that
For bigger applications it often makes more sense to use Django
That is from what I have heard, as many of the flask libraries are made by different people and there is no guarantee that they will keep developing them for example 3 years from now
But tht is from what I have heard, haven't had real world experience with this myself, but I often see when searching how to do something with flask that with Django there is already a tool for that

Which framework is this?

aiohttp
haughty root
I heard only about flask, django and aiohttp
quick cargo
Quart is legit just async flask
haughty root
And sanic?
quick cargo
Its a lower level Async framework thats much faster but you have to do alot of the stuff yourself
haughty root
O, I also heard about vibora, is it good?
quick cargo
But on the @aiohttp_jinja2.template("hello.jinja2") IIrc that decorator a should get awaited by the original call
I havent used it directly, I know some of their bench marks are a lil sketch
Looking at their github aswell development seems to of stalled
