I get also error 503
.
Probably it is very old example - it uses http
but modern pages use https
- and amazone
could rebuild page and now it has better system to detect spamers/hackers/bots and block them.
If I use @url http://toscrape.com/
then I don't get error 503
but I still get other error FAILED
because it needs some code in parse()
@scrapes Title Author Year Price
means it has to return item with keys Title Author Year Price
QUESTION
I have this crowdfunding platform that was initially using SafeMath library. And since is deprecated I'm looking for a workaround to make it compile and I'm getting a compilation error with remix in line 131:
...ANSWER
Answered 2021-May-31 at 12:05The Using X for Y expression extends the Y
datatype with functions of the X
library.
In case of using SafeMath for uint256
, it allows to use the functions defined in SafeMath (such as add()
) on uint256
variables.
Specifically, function add()
in SafeMath checks whether the addition would overflow the 256bit unsigned integer. If it did overflow, it throws an exception. If it didn't overflow, it returns the result of the addition.
QUESTION
I had this piece of code compiling in Solidity 0.6.0 without errors(I'm using Remix). But suddenly SafeMath library got deprecated because it wasn't necessary to import it anymore and I don't know how to fix this line:
uint raiseUntil = now.add(durationInDays.mul(1 days));
where I calculate a future date using the ¨mul¨ function.
I let you all code below. It's the backend of a crowdfunding platform. The raisedUntil variable is the date where the deadline of the crowdfunding project ends.
...ANSWER
Answered 2021-May-30 at 19:23You might decide to switch to a newer version of Solidity (current is 0.8.4), where now
is deprecated so I already used block.timestamp
instead. It's the same thing - now
was just its alias.
The SafeMath library checks whether an arithmetic operation (such as multiplication or addition) on two unsigned integers would overflow/underflow. If it would, it throws an exception. If it wouldn't, it performs the arithmetic operation. Since Solidity 0.8 this is done automatically and SafeMath is not needed, so another reason to use the current version.
In Solidity 0.8 and newer, if this would overflow, it would throw an exception automatically
QUESTION
I've built a Django API that uses django-graphql-auth and django-graphql-jwt packages to implement authentication. I followed the package's documentation and got everything to work and everything is working from my Angular UI. The only issue is that even requests made from Postman without the Authorization header, are able to fetch the data from the graphql API.
This is my Django project's settings.py

QUESTION
Hi I have finished my Django pycharm project and I'm now trying to upload it to heroku/ host it on heroku. I have followed this link https://medium.com/@qazi/how-to-deploy-a-django-app-to-heroku-in-2018-the-easy-way-48a528d97f9c which has actually successfully worked for me in the past. When I get to the step were you put this command in however 'heroku run python manage.py migrate' I continue to get this error message 'Running python manage.py migrate on ⬢ radiant-retreat-19016... up, run.6371 (Free) python: can't open file 'manage.py': [Errno 2] No such file or directory' Im not that much of a beginner so I know that my manage.py file is in the right place especially cause I can run ' python manage.py runserver '. I will attach the code to my procFile below along with my manage.py code and settings. I have looked everywhere on the internet for the problem and some people have it but nothing has worked for them. I will attach any other code if you need it. I even transferred all code to a new project and the same problem occurred.
...ANSWER
Answered 2021-Feb-20 at 04:45I finally figured it out after 10 hours. Other sources online were right. If you refer to the link I posted above at the very bottom command. If you run the git push stuff first than that last command and after that you run the heroku migrate command it should work. WAIT! If it doesn't work then if you have touched your git repository stuff or changed the name or messed with your squilte3 file and you didn't know what you were doing then transfer all your code to another project so the git stuff and squilte3 stuff automatically is made and resets then follow the instruction in this comment again. If not I don't know what to tell you but it worked for me.

QUESTION
I´m trying to generate translation file using command django-admin makemessages -l pt-br in Windows 10 but unfortunately the files aren´t generated. Here the steps that I followed:
- Installed gettext library from mlocati.
- I also tried several options from django i18n: Make sure you have GNU gettext tools , this process is more manual.
As the result when i run django-admin makemessages -l pt-br looks like that Django is executing something but the directory is not generated in the end.
Here are some peace of code that I have
views.py
...ANSWER
Answered 2021-Apr-28 at 11:59After several tryings and options. I found the error in my case.
If you install any gettext wizard installation some dependences library could not be instaled. (It was my case). According with the post django i18n: Make sure you have GNU gettext tools in the contribution of Far the problem it was fixed.
According with django documentation, the command "xgettext --version" must be run to enable internationalization command. In my case w64gcc_s_sjlj-1.dll it was out.

So I have been trying to customize the user model of my django program, my model.py looks like this
...ANSWER
Answered 2021-Apr-23 at 06:32Why not fire up a shell and retrieve an instance of your user:
c = costumer.objects.get(email="somest...")
Then check all the attributes. I feel like other_fields.setdefault('is_active', False) is a problem here. The user needs to be active in order to get access.
