@mortal mango I reproduced your issue...
if I use #!/usr/bin/env python3.8 at the top of the script it fails; if run python3.8 test.sh it fails. but if I run python test.sh it works for me. not sure why. This is all using pyenv installed pythons
mortal mango
oh so what do I do?

if I use #!python at the top then it works. 🤷♂️
mortal mango
wdym #!python
blissful slate
how are you running the script
mortal mango
VPS Ubuntu 18.04
mortal mango
I have a file called tests.py that was automatically installed
that one?
or do I create a new file and put #!python in it
@blissful slate
blissful slate
well what are you typing in to make the script go
mortal mango
python manage.py runserver
where do I import views in urls.py?
or where do I import it from
because I'm getting an error there
@blissful slate @devout coral do you guys know?
blissful slate
oh i thought you're running a script here. i dont know django very well
devout coral
Well the error you are getting now is what? Import problems in views?
mortal mango
I did from exo_api import views
and it says I have an error there
I have 2 folders named exo_api so i'm not sure if that's the problem or not
devout coral
Where is the file located that you are trying to import from?
Send me a screenshot of your directory tree please
mortal mango
I have the urls.py file inside the exo_api inside the exo_api
the one that's selected right now
should I rename it?
devout coral
No wait.
Could you send the entire tree. With the manage.py file and the root folder for the project
mortal mango
that's a screenshot I took yesterday so I don't have the folder with the models folder
devout coral
Ok, so where is the folder that has the models? Inside of the exo_api folder? Or in the root with manage.py
devout coral
Ok, now the second picture you sent. What folder is that?
mortal mango
and the urls.py file is in the exo_api folder
the second picture is inside the exo_api folder inside the exo_api folder
so the exo_api folder that's seen in the third picture
should I just rename the exo_api folder that's in the third picture
devout coral
No don’t do that. That will break it.
Give me like 5 minutes. I need to hop on a conference call
mortal mango
oh ok, take your time
devout coral
so your root folder is called exo_api correct?
devout coral
Yes
mortal mango
yeah it's called exo_api
devout coral
Then inside that folder you have another folder with the same name right?
mortal mango
yeah it holds urls.py, settings.py, etc
devout coral
These are the only files you need in there. It looks like some of the contents of the venv are in yours and your gitignore delete all of that other stuff
mortal mango
yeah those are the ones I have
I have a pycache folder inside that folder
should I keep that or delete it?
devout coral
Keep it. Granted if you delete it it will pop up. Those contain stuff that python packages use
devout coral
Cool

Yes. Get off the server. Start from the beginning on your computer and do not push the files until AFTER you have tested it.

devout coral
Alright. I suggest a tutorial or something first.
devout coral
Ok, because you are running into some really silly errors no offense.
devout coral
You are not
Just easier if you follow a tutorial to learn the basics then me explain all the errors
Do you like video tutorials?
If so follow that tutorial and you will learn a lot.
devout coral
@mortal mango Nice
mortal mango
I watched a couple minutes of the databases and migrations video and found out how to do it
devout coral
I thought you started from scratch...
mortal mango
and then I did makemigrations and it worked
devout coral
Yeah
mortal mango
yeah I started yesterday and then I stopped and continued today
mortal mango
yeah no more
it finally worked!!
so would I do a cname for a subdomain to point to the vps or would I do an a record in the dns
devout coral
I would suggest an A record
make sure you also set up your settings.py file to allow the host

Why is this not working in django (its a template html-file)
{% for comment in comments%}

<p id="comment_style">{{ commment.author }}</p>
It cant access comment.author the second time I want to use it
The first p-tag is working as intended and shows all the info

Guys. To run uWsgi with Flask, do I need to setup a virtual env ? I do have a Raspberry and my uWSGI seems to be unable to import libraries 🙂
manic grail
I have a noob question, what would I use JS for when creating a Flask app
quick cargo
frontend
manic grail
But css and html are there for it
dapper tusk
there are things you can only do with JS, such as infinite scroll
mortal mango
@devout coral hello again, I got the webserver and everything set up but it says forbidden You don't have permission to access this resource. when I try going to the page.
do you know why this happens?
devout coral
You need to give proper perms to whatever is running your server
mortal mango
yeah I did sudo chown -R :www-data exo_api to give apache access to all of my files
@devout coral

One more thing, is incorporating JS into html files made with templates (in Flask) the same as with Normal html?
devout coral
Not sure atm and I am leaving the office now. Sorry hope someone else can help.
mortal mango
oh ok
acoustic oyster
One more thing, is incorporating JS into html files made with templates (in Flask) the same as with Normal html?
yeah, it can work pretty much the same. I have used the<script>tag in django templates a few times and it did its job, this should be the same in flask.
mortal mango
I'm using django and I got an apache webserver and everything set up but it says forbidden You don't have permission to access this resource. when I try going to the page. Does anyone know why this happens?
mortal mango
yeah I have my domain and my vps ip address
acoustic oyster
hmmmm, this is usually an issue with allowed hosts. This may be an actual server permission error chmod
mortal mango
someone told me it's because apache can't access the files
so what should I do with chmod?
acoustic oyster
yeah, you need to give apache permission, one sec
mortal mango
I gave apache permission with chown
acoustic oyster
were you following a guide or tutorial?
mortal mango
did you follow the whole series?
acoustic oyster
you may want to try the permissions again then
sudo service apache2 reload
mortal mango
I didn't follow the whole series. I just watched that video to know how to deploy
acoustic oyster
I did follow the whole thing 😄
mortal mango
oh ok
sweet roost
anyone know if you can modify tags within a div using internal css?
I can modify the general section but cant seem to figure out how to modify each tag within specifically
mortal mango
@acoustic oyster in the tutorial it says to do something with the media files. I didn't do that because I don't have the media files. Is that fine?
I just reloaded it and it still says forbidden
acoustic oyster
is it forbidden on every page?
you may need to check your virtual host as well
mortal mango
yeah it's forbidden on every page
acoustic oyster
oh, double check you have the correct file paths in virtual host AND when you chmod, my project structure was a little different so I had some issues as well.
acoustic oyster
if these common solutions do not help, then you should check your apache error logs to see what exactly is happening.
well, follow the tutorial for chmod, but double check you are FORSURE doing the correct file paths.
And if you are doing the apache tutorial, you are probably using virtual hosts.
so, like cd /etc/apache2/sites-available and make sure your .conf is setup properly. Again QUADRUPLE check the file paths match your project

its from putyourapphere import views
vestal hound
my partner was trying to run my django project but cant run
from . import views, any idea why? I think the files are in their apprpriate folders
@plucky tapir what's the error
and where are you importing to
mortal mango
@acoustic oyster so where would I check the file paths? Would it be the aliases that I added?
plucky tapir
mortal mango
@acoustic oyster I don't have an html file. I'm using Django Rest Framework to build an API. Does it cause problems if I don't have an index.html file?
plucky tapir
@vestal hound
vestal hound
@plucky tapir that means that you're running code from within projects itself
plucky tapir
@vestal hound which is fine?
vestal hound
@vestal hound which is fine?
@plucky tapir not if you want to use it as a package.
for the purpose of relative imports
projects is only a package from the outside.
so if, from the root directory, you ran from projects import views, for example, that would work.
and if in projects you had a from . import views, that would work too
unless you were running it from that directory itself, in which case it wouldn't "know" that it was a package, therefore there'd be no parent (.) to import from
acoustic oyster
@acoustic oyster I don't have an html file. I'm using Django Rest Framework to build an API. Does it cause problems if I don't have an index.html file?
You need to double check how your project is structured and that you included the correct files in your virtual host setup in/etc/apache2/sites-available(is where I think it should be.
You would need to double check that your setup matches the tutorial setup
vestal hound
outside the projects folder?
@plucky tapir how are you running it?
from terminal?
what's your PYTHONPATH?
plucky tapir
through terminal and pycharm it runs fine for me. I'm not sure what setup or IDE they're using tbh. And I'll have to look that up real quick
@vestal hound and one small question for user to link to database info, its currenlty linked to user, should it be to the user ID?
vestal hound
through terminal and pycharm it runs fine for me. I'm not sure what setup or IDE they're using tbh. And I'll have to look that up real quick
@plucky tapir pretty sure it's a path issue.
if you run code from within a package relative imports won't work because there's no parent package to import from.
and that's basically the only case in which you get that error.
@vestal hound and one small question for user to link to database info, its currenlty linked to user, should it be to the user ID?
@plucky tapir could you elaborate? I'm not really sure what you mean
plucky tapir
appreciate it.
So I'll probably have to try to get their paths in order. I didn't upload my virtual environment since it was too large, is that have anything to do with setup
Sure, right now in Django a user logs in, they use create views and input data. the models.py takes in the user as an author automatically to know who created that in the database
so takes in user as a foreign key
should it take in the user id instead of the user? For good practice
vestal hound
should it take in the user id instead of the user? For good practice
@plucky tapir do you mean in terms of how the related field is defined in theModel?
appreciate it.

@plucky tapir perhaps. it should just work out of the box though, which makes me think they're not running it properly
like python manage.py runserver should not run into any problems
plucky tapir
@vestal hound yep I believe so, right now its author = models.ForeignKey(User, blank=True, null=True, on_delete=models.CASCADE, default=None)
vestal hound
yup
so ForeignKey abstracts away the idea of ID/primary key for you
but internally what happens is that it creates an author_id field and sets up the necessary FK constraints
so in fact, you'll notice that on the model you can access both author (User object) and author_id (int).
plucky tapir
Oh wow okay I'll have to try that out to see. Itd be django acceptable to leave it as User ?
vestal hound
Oh wow okay I'll have to try that out to see. Itd be django acceptable to leave it as User ?
@plucky tapir not just acceptable, but preferred
although I question why your FK is nullable
not wrong but I'm curious
plucky tapir
@vestal hound alright nice.
@vestal hound Tbh I had some issues at the time with the foreign key, I read through some forums and found someone added blank and null. So still learning but if it’s more conventional to switch it up I’m for it.

@plucky tapir IMO don't use nullable FKs unless you know what you're doing
there's a fair bit of theory behind this
which you can get into if you're interested (it'll help you design better schemata)
but in this specific context...would it make sense to have an instance of whatever model that is without a creator?
plucky tapir
@vestal hound I could learn if it’d help me out more down the line.
For now I believe so
the user is inputting info that is specific to them
cerulean otter
@app.before_request
def before_request():
database.connect()
@app.after_request
def after_request(response):
database.close()
return response
By default, all your application needs to do is ensure that connections are closed when you are finished with them, and they will be returned to the pool. For web applications, this typically means that at the beginning of a request, you will open a connection, and when you return a response, you will close the connection.
I got this from peewee's documentation. Isn't it a bad idea to recycle a single connection per request? What if you're doing a lot of async stuff? Wouldn't it be better to pull a new connection from the connection pool everytime you do a query. Immediately after you're done you would close the connection so it goes back into the pool
WIth the above solution, each request will have a single connection to play with. The bad side about this is if you have a number of async db calls, all but one is going to be blocked
Anyone ;(. Every thing I've researched suggests that this is a bad idea
Oh wait there is a db channel
pine yew
anyone have opinions on web frameworks? Looking for things to learn besides Flask
I've been hearing good things about FastAPI, but I had a terrible experience with Connexion so I'm a little hesitant about things that are new
acoustic oyster
I am heavily biased towards django always xD but django is 
gaunt marlin
Django is good if you want a quick admin system(customize admin is hell though, not recommend), FastAPI exactly what it's name is to make API super fast(i also love the force typing in api though, from someone who worked with typescript). If you want to do from scrap Flask not a bad choice
in the end use what you need, not which is better
sturdy pike
@gaunt marlin most of the jobs are with front end / react if you have the free time to pick up additional frameworks go with react imo
If you can get good with vanilla css and efficient in react you're solid
@pine yew
gaunt marlin
but those are frontend framework, you always need backend frameworks for server. 2 Different stuffs
sturdy pike
Sorry I didn't mean to cc you I thought you were the one asking. Also, yeah I understand, however I think he just asked about a framework not a backend or front one specifically. I'm sure he's interested in backend being as this is a python discord it's just that personally I feel anyone with free time to pick up a framework who wants work, should learn something like react. Plus he said he already knows Flask. I'm a Django guy myself but I just see where the trends are for work etc. Personally you can do a lot more with django and if you already know flask, django may be the best option since there will be less of a learning curve and django can do more for you out of the box. So perhaps my ultimate suggestion would be to become as profficient as you possibly can without stopping with django. In the mean time don't look at any other frameworks unless you're already in the field then I'll stop right there

What is the best way to handle object level permissions in django? hit a bit of a road block on this one.
or, better suited, row level permissions
say I have a table full of quotations, with 1 column being customer
and each "user" is attached to a customer
user being foreign key to a customer in a customer table
how can I ensure each user can only see rows in the quotation table, for which the foreign key is the same customer as his user.customer is?
slow briar
Do you guys know some good servers for help with Pyramid Framework?
vestal hound
What is the best way to handle object level permissions in django? hit a bit of a road block on this one.
@idle flame vanilla Django?
slow briar
I never understood how Django works, so I'm going with Pyramid. Can anyone recommend me some Pyramid servers?
idle flame
@vestal hound yes, i intend putting DRF ontop of it
but pretty much vanilla
still in early development so I can certainly rework something else into it. I've googled the issue to little avail, it seems postgres has something I can integrate to assist but im running on mysql
django guardian but there seems to be some concern it's not applicable to my use case
vestal hound
@vestal hound yes, i intend putting DRF ontop of it
@idle flame okay it depends on whether that's going to be a general thing or specific to your view
if the latter, then your filter should be in the queryset
idle flame
drf mentions object level permissions but the implementation but that only applies to api calls right?
vestal hound
drf mentions object level permissions but the implementation but that only applies to api calls right?
@idle flame basically, yes.
but where else would you perform that check?
like I believe for that case you want Quotation.objects.filter(customer=request.user.customer)?
idle flame
bare with me, I'm self teaching here and seem to have hit the limits of my basic understanding. so I'm not running an API call when on the website - only when I'm using the api itself (i'm using it for sending sensor readings into the database)
I also dumbed the query down a little bit - so I have user.organisation (the organisation the user belongs too)
but then on the other side of the query I have organisation.location.area.zone.asset.quotation
and other tables than quotation,
idle flame
exactly 🙂
vestal hound
okay, but that's all irrelevant
the thrust of the issue is that you only need to impose control at one point: when your API returns data
correct?
idle flame
its actually the opposite 😦
vestal hound
why?
idle flame
the only thing using the API is embedded software i've designed
so a little data collector pushing sensor readings to a database
then we analyse the data, make reports in a "report" table
and there are reports many to one asset
of which asset many to one zone, then area, then location then organisation
does it make sense :S
and users will need permissions for different levels of that hieracy
vestal hound
I mean, all that makes sense
surreal harness
has anyone ever used django rest framework? i'm having trouble using nested serializers. i can't get the nested models to show on my api view
vestal hound
has anyone ever used django rest framework? i'm having trouble using nested serializers. i can't get the nested models to show on my api view
@surreal harness what's your specific problem
I mean, all that makes sense
@vestal hound but ultimately, either your API does the permission checking or your embedded software does, right?
surreal harness
i have two models, User and UserContactInformation
UserContactInformation has foreignkey(user)
and i want to nest the contactinformation in the user model in the serializer
so when i go to /api/users/1 it will show the user attributes and the nested contact information
idle flame
so what I'm ultimately trying to achieve is: users cannot see or interact with assets from other users.
For my use case you recommend applying it via the queryset?
vestal hound
so what I'm ultimately trying to achieve is: users cannot see or interact with assets from other users.
For my use case you recommend applying it via the queryset?
@idle flame yes. why would the embedded software know about such things?
which is why I'm saying you should control access at one point: your API
surreal harness
class UserContactInformationSerializer(serializers.ModelSerializer):
class Meta:
model = UserContactInformation
fields = ['id', 'user', 'contact_information']
class UserSerializer(serializers.ModelSerializer):
user_contact_information_set = UserContactInformationSerializer(many=True, read_only=True)
class Meta:
model = User
fields = ['id', 'first_name', 'last_name', 'user_contact_information_set']
apparently this is supposed to be enough to get it to show properly nested, but it just won't show the nested contact information
idle flame
the embedded software doesnt know or care, no permissions required. it only knows the asset_id
vestal hound
the embedded software doesnt know or care, no permissions required. it only knows the asset_id
@idle flame precisely, right? so it should let the API handle it.
idle flame
yes, the API will handle it.
vestal hound
class UserContactInformationSerializer(serializers.ModelSerializer): class Meta: model = UserContactInformation fields = ['id', 'user', 'contact_information'] class UserSerializer(serializers.ModelSerializer): user_contact_information_set = UserContactInformationSerializer(many=True, read_only=True) class Meta: model = User fields = ['id', 'first_name', 'last_name', 'user_contact_information_set']apparently this is supposed to be enough to get it to show properly nested, but it just won't show the nested contact information
@surreal harness what do you mean "won't show"?
what output do you get
idle flame
BUT the user goes to the website and views the reports
vestal hound
BUT the user goes to the website and views the reports
@idle flame okay, so the embedded software has to know which user is using it
idle flame
no -
surreal harness
I only get first_name, last_name, and id without even seeing a field for user_contacT_information.
},
{
"id": 4,
"last_name": null,
"first_name": "test user",
}
}
the software sends the data in, I parse it and save it in the table on the back end side
data comes in via API, back end processes it and stores it in a table
vestal hound
the software sends the data in, I parse it and save it in the table on the back end side
@idle flame if it doesn't then it can't perform permission checking
because ultimately the backend has to know which user is requesting data
idle flame
django has to permission check
vestal hound
to do that, right?
and for the backend to know, the previous layer has to know, too
idle flame
Sorry - i'm a beginner here - the embedded for all purposes is a superuser
it handshakes and sends the data in via api. django then reads and processes this data, then stores it in the relevent table
the user logs into the front end of website and views this table
i need to restrict the user to only objects in this table that belong too him
because there are hundreds of embedded components
on 20 customers
in 100 different locations
vestal hound
i need to restrict the user to only objects in this table that belong too him
@idle flame yup, I understand that
but the thing is
the user logs into the front end of website and views this table
@idle flame you can't have validation purely on the frontend.
the backend has to know which user is requesting data
otherwise the only choice is to send all the data.
idle flame
ohh yes -
it does!
the default django user model
I extended this
well i one to one'd a user profile
vestal hound
so each request has to know the source user
yeah, those are details
but the main thing is that if each request is tied to a user
then the problem is trivial
idle flame
so when user makes a request, I look at this query, crawl around the tables linked to his to see where is view permissions end
then crawl the table he is trying to view and pull only things he has permission for
native tide
Why don't image show up on my Django app
idle flame
okay. I know this is a really dumb question but where is that applied?
vestal hound
so when user makes a request, I look at this query, crawl around the tables linked to his to see where is view permissions end
@idle flame in what form are the user's credentials transmitted?
okay. I know this is a really dumb question but where is that applied?
@idle flame not a dumb question, but where is what applied?
idle flame
its currently NOT that's what I'm trying to build - sorry beginner here. i wanted it to work via @ login required
and extend this to the user
so he needs to send his user to django and then I need to apply it from this on every page
vestal hound
yup
precisely!
so like
with Django REST framework
each view takes a request, right
and if you set up your authentication backend properly
idle flame
yes
vestal hound
you can just access request.user
and that will be a User object representing the user asking for data.
then you can just query the Quotation table with the filter I mentioned above
Quotation.objects.filter(customer=request.user.customer)
idle flame
at the moment I have only the django base authentication back end and I dont know how to extend it and apply it
cosmic aspen
a good book to learn django please ??
idle flame
i'm alot further forward so far, sorry @vestal hound this is alot more helpful than it seems. So basically I need to google "extending django authentication back end" instead of "how to enforce object level permission django??"
vestal hound
i'm alot further forward so far, sorry @vestal hound this is alot more helpful than it seems. So basically I need to google "extending django authentication back end" instead of "how to enforce object level permission django??"
@idle flame DRF comes with several authentication backends
you can look into those and see if they fit your usecase
so that's one part of the problem
once you handle that, the rest should be easy
because it'll take care of populating the user attribute of the request object
that's one part.
but do you understand
what I mean by this?
idle flame
but that will only apply to API calls right? not
vestal hound
then you can just query the
Quotationtable with the filter I mentioned above
@vestal hound this
idle flame
wait
vestal hound
but that will only apply to API calls right? not
@idle flame yes, but the backend only interacts with the outside through API calls, right
surreal harness
a good book to learn django please ??
@cosmic aspen try looking at this book called two scoops of django
vestal hound
I could change my front end to route via the API though
@idle flame yes, but that's a separate layer
the main point is that the data ultimately comes from the backend
idle flame
but DRF sits ontop of the back end though? doesnt a standard web browser going to the website
avoid this
idle flame
so it goes website ->drf -> backend??
vestal hound
DRF is the backend
also, I think you might be a bit confused regarding object-level permissions
basically, normal permissions: "can this user access this view?"
object-level permissions: "this user can access this view, but can they also access this object?"
vestal hound
which is kind of neither here nor there, but just a point
idle flame
I'm worried that if I make the view it's going to show them everything
(which it is right now)
vestal hound
because object-level permissions are more something you do when you want to get a single object
idle flame
that is the bit I'm trying to fix
vestal hound
in this case it's a question more of filtering a number of results
idle flame
okay, I think I need to work DRF in and read it's docs
do you mind if I work on this for a while and message you later?

}
}
can I see your models
surreal harness
yeah
vestal hound
User and UserContactInformation
surreal harness
well okay, I sort of reduced the complexity to make it easier to write out
the actual model is like
vestal hound
and also your view
surreal harness
class CandidateContact(models.Model):
class Meta():
db_table = 'candidate_contact'
candidate = models.ForeignKey(Candidate, on_delete=models.CASCADE)
contact = models.ForeignKey(
ContactType, null=True, on_delete=models.SET_NULL)
contact_detail = models.CharField(max_length=255)
class Candidate(models.Model):
# TODO: Confirm usage of email/phone with the mobile developers as identifier, as opposed to UUID
class Meta():
db_table = 'candidate'
id = models.AutoField(primary_key=True)
last_name = models.CharField(max_length=255, blank=True, null=True)
first_name = models.CharField(max_length=255)
gender = models.ForeignKey(
Gender, default=3, null=True, on_delete=models.SET_DEFAULT)
country = models.ForeignKey(
Country, verbose_name="nationality", null=True, on_delete=models.SET_NULL)
class CandidateContactSerializer(serializers.ModelSerializer):
class Meta:
model = CandidateContact
fields = [
'id',
'candidate',
'contact_detail',
'contact'
]
class CandidateSerializer(serializers.ModelSerializer):
# Retrieve connected fields
candidate_contacts = CandidateContactSerializer(
many=True,
read_only=True,
)
class Meta:
model = Candidate
fields = [
'id',
'last_name',
'first_name',
'gender',
'country',
'candidate_contacts',
]
@api_view(['GET', ])
def candidate_detail_view(request, id):
try:
candidate = Candidate.objects.get(id=id)
except Candidate.DoesNotExist:
return Response(status=status.HTTP_404_NOT_FOUND)
if request.method == "GET":
serializer = CandidateSerializer(candidate)
return Response(serializer.data)
# Try class based view
class CandidateListView(ListAPIView):
queryset = Candidate.objects.all()
serializer_class = CandidateSerializer
# authentication_classes = (TokenAuthentication)
# permission_classes = (IsAuthenticated)
pagination_class = PageNumberPagination
I suppose Candidate corresponds to User?
surreal harness
no, its a database filled with some master data
a bunch of people previously registered
to some other service
vestal hound
no, I mean, in your example above
surreal harness
oh yes
this is the view on /api/candidate/1
HTTP 200 OK
Allow: OPTIONS, GET
Content-Type: application/json
Vary: Accept
{
"id": 1,
"last_name": null,
"first_name": "Võ Minh Luân",
"gender": 3,
"country": 235,
"education_in_japan": false
}
as you can see, candidate contact isn't showing up at all. i'm wondering if its because i'm not defining the relationship correctly
vestal hound
that's your function-based view, right?
vestal hound
weird my internet isn't working at all
I want to Google something but I can't
sec
surreal harness
ok
unborn dust
has anyone used python-social-auth with django?
vestal hound
ok
@surreal harness okay this shouldn't be happening
vestal hound
try deleting all your .pyc files?
that's my best guess
there's only one CandidateSerializer, right
like you're not importing one that doesn't have that field
surreal harness
nope
as in yes, there's only one
i have a feeling that
something is messed up with the relation
vestal hound
it looks fine to me
surreal harness
so we know that CandidateContact uses Candidate as a foreign key
vestal hound
although
surreal harness
but is the serializer doing that
surreal harness
should it matter? the database exists
vestal hound
because Candidate doesn't exist when CandidateContact is defined
class CandidateContact(models.Model):
class Meta():
db_table = 'candidate_contact'
candidate = models.ForeignKey(Candidate, on_delete=models.CASCADE)
purely as a matter of Python
at this point, Candidate is not yet defined, right
like this shouldn't cause that problem, but just a point
surreal harness
right true, well in the models Candidate is defined first
vestal hound
anyway, that is more or less how you should define a nested field, so I don't think it's that
surreal harness
in the serializers CandidateContact needs to be defined first since Candidate depends on it, I think
surreal harness
yeah I followed this guide exactly, but didn't seem to work
came across something that said that query_sets retrieved by the serializers have a default naming convention of having the word set appended to them
however even when adding the word set, as in 'candidate_contact_set' and having the fields include 'candidate_contact_set' instead of just 'candidate_contact', same result
vestal hound
came across something that said that query_sets retrieved by the serializers have a default naming convention of having the word
setappended to them
@surreal harness this is true
but it shouldn't matter
surreal harness
interestingly enough applying depth=1 inside of the Meta class for the Candidate model automatically nests stuff like gender, etc.
vestal hound
I'm actually not sure how this works because I always set custom related_name
surreal harness
I see
vestal hound
let me try
surreal harness
class CandidateSerializer(serializers.ModelSerializer):
# Retrieve connected fields
candidate_contacts = CandidateContactSerializer(
many=True,
read_only=True,
)
class Meta:
model = Candidate
fields = [
'id',
'last_name',
'first_name',
'gender',
'country',
'candidate_contacts',
]
is what it is currently
vestal hound
okay can you try this
in CandidateContact.candidate, set related_name to "candidate_contacts"
so like models.ForeignKey(Candidate, related_name='candidate_contacts', on_delete=models.CASCADE)
this is my best guess
surreal harness
does that require a migration
ah it does. give me a second
does it being plural actually make a difference
vestal hound
my thought process is
if the attribute name is wrong, it can't find the attribute representing the related objects, therefore it assumes that it's null
does it work
surreal harness
about to test
i just have to deploy it and shit, it takes a second
yeah, that worked
vestal hound
okay
so I guess my mental model was accurate
your serializer field name needs to correspond to the related object manager
full steppe
can flask be used for front end web dev
surreal harness
If you don't specify a related_name, Django automatically creates one using the name of your model with the suffix _set, for instance User.map_set.all().
this is what i see, however i distinctly remember trying this
let me try again
full steppe
k
surreal harness
yeah, so when trying to add another relation it seems like this thing they say is actually not true
i have some other related fields and simply appending 'set' to the field name doesn't do anything
vestal hound
uh
I am actually not sure about this, because like I said, I always use custom related_name
which IMO is a good practice
surreal harness
okay, i just don't really know what it represents conceptually
vestal hound
okay
humble elbow
hello
vestal hound
so like
candidate = models.ForeignKey(Candidate, on_delete=models.CASCADE)
each ContactInfo has a Candidate
humble elbow
how can i log in to my robot
vestal hound
which you can access with, say, contact_info.candidate
but since it's a foreign key (one to many relationship)
surreal harness
yep
vestal hound
each Candidate has many ContactInfos
so candidate.candidate_contacts.all() is the QuerySet of ContactInfos corresponding to that Candidate
where candidate_contacts is the related_name you set
surreal harness
is candidate.candidate_contacts.all() even possible
surreal harness
right, but from the candidate model perspective no relationship is set
that only exists in the contactinfo model
vestal hound
it's more or less the same as ContactInfo.objects.filter(id=candidate_id)
no
it is
surreal harness
i see
surreal harness
ok, got it
the thing is
candidate.candidate_contacts.all()
that candidate_contacts part, that name corresponds to what exactly
vestal hound
the related_name
surreal harness
RIGHT
vestal hound
if you change related_name to monkeys it'll be candidate.monkeys.all()
surreal harness
ok now i really get it
oh ididn't see th elast sentence of what you wrote is why
and basically if I never set that name it should default to something
which i assumed was just the model name defined with underscores and appended with 'set'
but i guess that's not true
but now i know how to check
surreal harness
what happens i think is that
if you define a model like
camel case, it will not apply underscores
surreal harness
so it would just be candidatecontactinformation_set
vestal hound
for models
vestal hound
in this case it should be contactinfo_set

@fickle fox PDF and image are file so you only need to handle store file to database here a good tutorial https://www.youtube.com/watch?v=TLgVEBuQURA&ab_channel=PrettyPrinted
fickle fox
oh thanks
i am following that guide
tho i found some errors in my code qwq
oh never mind i fixed it hahahah
surreal harness
how could i implement a count_only query parameter in the rest framework that would only count the total number of results without paginating them?
gaunt marlin
@surreal harness use .count() at the end of the query it will return the number instead
in your view query
surreal harness
hm...looks like that might be incompatible with the pagination class

it's displaying the th portion of the code, but not the content of the query
devout coral
@mortal mango Did you get that error figured out?
swift sky
when i inspect the html while it's running
devout coral
@swift sky have you done a print in staffdashboard() to ensure that data has something?
swift sky
there are no elements from my query present
so i think it's a jinja2 issue
@swift sky have you done a print in staffdashboard() to ensure that data has something?
@devout coral yes it pulls the correct information
mortal mango
@devout coral yeah I did but now I have Internal Server Error
devout coral
Ok. could you put the following code for me in that stafffunctionboard() function and show me the result. @swift sky
for item in data:
print(type(item))
@mortal mango Do you have debugging set to false?
devout coral
@swift sky ok now do this for me please:
for item in data:
print(item)
yeah but it's gonna be different data every time
also, I already have a dictionary being passed in my view function
devout coral
@mortal mango In development you should keep it on yes. But you should not be developing in a public server.
pine yew
@swift sky you're iterating a dict wrong
swift sky
@swift sky so do the following:
{% for key, values in data.items() %}
<tr>
<td> {{ value }} </td>
<td {{ key }} </td>
</tr>
{% endfor %}
<tbody>
{% for item in data.items() %}

<td>{{item[1]}}</td>

@devout coral I'm on my VPS
I'll transfer the files to my computer and test on my computer and then push it to my VPS
pine yew
@devout coral you can't unpack a k,v from a dict, you need .items()
devout coral
@pine yew I know, that is why I edited my thing. I missed the .items()
pine yew
didn't see your edit - was typing 😛
devout coral
@mortal mango I mean it does not seem like you care too much about security so just do it on the server.
devout coral
@pine yew Lol, yeah I also missed a few closing tags for the html
swift sky

@pine yew i did this one
pine yew
data = cursor.fetchmany(1) do you know what fetchmany returns?
mortal mango
@mortal mango I mean it does not seem like you care too much about security so just do it on the server.
@devout coral yeah I'm not sure how to configure security stuff so yeah
pine yew
it should be an iterator over db rows
swift sky
i actually chagned it to fetch all
devout coral
@mortal mango I mean, it does not matter at this point.
mortal mango
yeah ok
swift sky
but i havent decided, I'd probably need like the last 3 entries or something
pine yew
@swift sky what does your schema look like?
mortal mango
so do you know why it says internal server error?
swift sky
if by schema you mean the dict keys
devout coral
@mortal mango Just put debbuging to true in your settings.py and you will get a traceback
swift sky
content_id = db.Column(db.Integer, primary_key=True, autoincrement=True)
load_date = db.Column(db.DateTime)
content_type = db.Column(db.String(20))
content = db.Column(db.String(10000))``` @pine yewoh you're using an ORM? why are you accessing a DB query directly?
there's a lot of WTFs going on right now lol
swift sky
thanks
pine yew
are you using sqlalchemy then?
pine yew
yeah, what driver you use shouldn't matter
you can just access the model, that's the whole point of the ORM
swift sky
ahh ok
pine yew
is your class name Content?
swift sky
yes
pine yew
are you using Flask?
swift sky
yes
pine yew
Flask-sqlalchemy?
swift sky
yes
pine yew
OK! So here goes
content = Content.query.all()
pass that into your render and access the class names as expected
{% for item in content %}
item.content_id
etc
this is covered in their documentation:
https://flask-sqlalchemy.palletsprojects.com/en/2.x/queries/
swift sky
one second
{% for item in content %}
<tr>
<td>{{item.content_id}}</td>
</tr>
{% endfor %} ```?hmmm well
is there a way to do this without the orm
because i have some import errors to deal with
and thas a major headache
@pine yew
pine yew
@swift sky you could use the cursor like you were, but what's your headache with the orm?
swift sky
I have to refactor my code
pine yew
ah, I see
swift sky
i have issues with imports
I guess that's why I was doing it directly
{% for item in data.items() %}
jinja2.exceptions.UndefinedError: 'list object' has no attribute 'items'
no worries
swift sky
what do you mean?
you fetch it then close the connection
then you render the template with the data you fetched
pine yew
so I don't know how pymysql does it, but most DBAPI implementations will close your connection when it leaves scope automatically
the fetch calls are generators
they don't do anything until you consume them
swift sky
the reason i added the close connection call was because my db would overload otherwise
it would keep them open
pine yew
yeah, flask gives you the bare minimum then tells you to find some extensions
pine yew
that error being?
swift sky
{% for item in data.items() %}
jinja2.exceptions.UndefinedError: 'list object' has no attribute 'items'
well you're not dealing with a dict when you use a cursor
you're dealing with rows of a db
which is an iterator of tuples
swift sky
yeah from what I googled some stack overflow post defined the data in a dict and then explicitly called the key using dotstring
pine yew
always good to refer to the docs.
https://pymysql.readthedocs.io/en/latest/modules/cursors.html
if you want to access your rows as a dict, you need a DictCursor
swift sky
i do actually
def db_connection_content():
return pymysql.connect(host=os.environ.get('HOST'),
user=os.environ.get('PYMSQL_USER'),
password=os.environ.get('PASSWORD'),
db='content',
charset='utf8',
cursorclass=pymysql.cursors.DictCursor)```
winter spindle
hey
swift sky
i guess then it depends how im connecting to the db?
wether it's through the ORM or through pymsql
.>
winter spindle
is this possible to make with flexbox ?
pine yew
@winter spindle no, you need a grid. flexbox is 2D
winter spindle
ohh okay then thanks
pine yew
er, 1D?
if the box of four is one element
then you could use a flexbox
but that would be very straightforward in grid
swift sky
oh nvm
i googled some stuff
cursor = connection.cursor(pymysql.cursors.DictCursor)
lets see
pine yew
@swift sky
def staff_dashboard():
conn = db_connection_content()
cursor = conn.cursor()
cursor.execute('SELECT * FROM roll_call')
data = cursor.fetchall()
try:
fragment = render_template('''
{% for item in data %}
<tr>
<td>{{ item[1] }}</td>
</tr>
{% endfor %}
''', data=data)
return render_template([..])
finally:
cursor.close()
conn.close()
you can also use the name instead
item['content'] or whatever
pine yew
it's just another thing you inject into your template
pine yew
yeah
swift sky
how does it know to place in the []
pine yew
so instead of
<tbody>
{% for item in data.items() %}
<tr>
<td>{{item[1]}}</td>
</tr>
{% endfor %}
</tbody>
you have
<tbody>{{ fragment }}</tbody>
that's just a placeholder, you put your other arguments there as usual
I was being lazy
pine yew
yeah
swift sky
as well as any other args
try:
fragment = render_template('''
{% for item in data %}
<tr>
<td>{{ item['content'] }}</td>
</tr>
{% endfor %}
''', data = data)
return render_template(["staffdashboard.xhtml", dict_to_be_passed=parse_311_sitemap(load_articles())])
finally:
cursor.close()
connection.close()```but it's not accepting dict_to_be_passed= as a kwarg anymore
or positional, whichever it is
swift sky
oh ok
pine yew
return render_template("staffdashboard.xhtml", dict_to_be_passed=parse_311_sitemap(load_articles()), fragment=fragment)
you'll need to change your html
swift sky
testing
some errors
''', data = data)
line 89, in _get_source_fast
raise TemplateNotFound(template)
jinja2.exceptions.TemplateNotFound:
{% for item in data %}

</tr>
{% endfor %}
im gonna try with just the [1]
pine yew
you need to import it from flask
pine yew
did you pass it into the template?
swift sky
<table>

<th>Load Date</th>
<th>Content Type</th>
<th>Content</th>
<tr/>
</thead>
<tbody>
{% for item in data.items() %}

{% endfor %}

Get rid of the tbody content entirely
just replace it with {{ fragment }} like I suggested above
swift sky
<table>
<thead>
<tr>
<th>ID</th>
<th>Load Date</th>
<th>Content Type</th>
<th>Content</th>
<tr/>
</thead>
<td>{{ fragment }}</td>
</table>```well
i managed to navigate to the site
without the server errors
however
ID Load Date Content Type Content
<tr> <td></td> </tr>
that is what was rendered
im gonna get rid of <thead> <tr> <th>ID</th> <th>Load Date</th> <th>Content Type</th> <th>Content</th> <tr/> </thead>
uhh
it just shows up as ```Roll Call
<tr> <td></td> </tr>
so these are not being passed i think
<td>{{ fragment }}</td>
alrighty
getting closer
<tr> <td>testing some content</td> </tr>
thank you @pine yew

Try small webserver like gunicorn or something, they are very easy to setup
peak meadow
Hmm, it's a simple API, the input matters, the output is just a string like "succes"
@abstract kite

@peak meadow ~~still i would recommend a webserver, try this, hardly 2 commands are required to set it up 😅
https://gunicorn.org/~~
mortal mango
@devout coral it still says internal server error
peak meadow
Sure. I will try gunicorn then, thank you @abstract kite
devout coral
@mortal mango So it is something with your server then. When does the error occur or how does it happen?
toxic flame
mortal mango
@devout coral same error as last time
pine yew
@abstract kite what are you even talking about
@peak meadow the werkzeug web server is fine for development purposes locally
abstract kite
@abstract kite what are you even talking about
@pine yew ?
Eh my bad, I read it as same network and not same computer. I think I should go get some sleep
mortal mango
@devout coral Do you know why this is happening? I've had this error since yesterday night. I'm pretty sure I have my .conf set up properly.
devout coral
You running on Ubuntu? With Apache 2?
mortal mango
yeah
devout coral
And what do they say?
Do you not have a requirements.txt file which you installed all your modules from?
mortal mango
no, I manually installed everything
devout coral
Well you missed a module. Called encodings
mortal mango
oh so pip install encodings
devout coral
Yes
mortal mango
it says 404 client error
devout coral
I suggest you go and find the package in pypi and just copy the download command
mortal mango
ok I'll do that
do you know the package name?
there's a bunch of packages with the word encodings in it
@devout coral
devout coral
I don't even know what your project is... Let alone a specific package you are using.
My guess is that it is a dependency for one of your other packages.
glacial quartz
hmm this
Quart
on Hypercorn
does it multythread, can i share a global class?
like can i have a global class mygame that evry connection can access?
mortal mango
My guess is that it is a dependency for one of your other packages.
@devout coral I haven't done anything. Pretty much all of my code is default.
glacial quartz
guess time to test
devout coral
@mortal mango What do you mean "all of my code is default"?
mortal mango
like the manage.py and the settings.py and the other files
mortal mango
oh ok
devout coral
As I suggested yesterday. You should first develop your application in a test environment and then later deploy it. Because developing in a "production" environment just adds more variables for when things go wrong.
mortal mango
but I would need apache on my computer then, right?
devout coral
No. Django has a built in test server.
mortal mango
oh ok, I'll test that then
devout coral
You don't need to set up apache or anything like that. you just do python manage.py runserver
And if you are using an IDE, like pycharm, the chances of it telling you exactly which package is missing is high.
mortal mango
oh ok. I use VScode.
but is there a way I can get my secret key
I put it in a config.json and I tried opening it but theres nothing inside it
it seems to not have saved
devout coral
Just generate a new one.
mortal mango
how do I do that?
devout coral
mortal mango
so it's something wrong with my apache config right?
devout coral
So no more errors? You were just missing your secret key?
devout coral
Wait, it is working in your development server and not on the server?
mortal mango
I don't have a virtual environment on my computer
mortal mango
I use the same version of python everywhere so I don't use them
I'll start using them
I've never thought I need them so I didn't
but I'll just pip freeze everything on my computer
devout coral
Ok, from this day forward please use Virtual Environments. Otherwise if you work with different versions of packages you will run into issues
@mortal mango Do not pip freeze everything
mortal mango
ok I will
devout coral
Unless this is the only project you ever worked on with third party libraries
devout coral
I still do not suggest it. Then you will get random packages in your project. Just make a new venv just for this project.
devout coral
Should be yes
devout coral
Did you just download the venv files from your server?
devout coral
So then you will have to create the environment. However, I think VS code has a thing to create it for you
Take a look at that
I do not use VS code so I cannot help too much with that.
Once you got it though let me know
mortal mango
ok
I don't think that makes an environment
I think it just tells you how to change interpreters and stuff
if I move the virtualenv.py file into my exo_api folder, and then I do python virtualenv.py will it activate the virtual environment inside that folder?
devout coral
That is not how you activate the environment no.
mortal mango
oh
devout coral
I think it is source path_to_activate_script
mortal mango
in the cmd window in my directory?
devout coral
I would suggest you put the venv folder in the root of your django project along with the mana.py file
Then cd into the root folder of your django folder and do the activation there
devout coral
Well I would suggest to make a new one. Then set up vs code for that to be the interpreter for that project.
mortal mango
so delete the one I have right now?
I would suggest you put the venv folder in the root of your django project along with the mana.py file
@devout coral do I make a new folder called venv or is the venv folder somewhere?
devout coral
The one in your computer yes.
The simplest way is just to make your venv with vs code...
Ok so just make a new vitual environment then follow this to set it up in vs code.
https://stackoverflow.com/questions/54106071/how-to-setup-virtual-environment-for-python-in-vs-code
@mortal mango
mortal mango
oh ok
I have my venv selected
so do I have to do all my cmd commands in vscode for the virtual environment to work?
@devout coral
mortal mango
yeah I have a terminal
so now do I just run it and install everything when it pops up an error
devout coral
just try to run the server now through that terminal
mortal mango
it worked
so now do I push it to my vps?
wait so how did it work?
I didn't install anything
oh wait nvm
devout coral
No, now do the pip freeze
